Groundbreaking Results Shift Treatment Paradigm in High-Risk Smoldering Multiple Myeloma 04/02/2026

Groundbreaking Results Shift Treatment Paradigm in High-Risk Smoldering Multiple Myeloma Dr. Monty Pal speaks with internationally acclaimed hematologists Dr. Vincent Rajkumar and Dr. Saad Usmani about the AQUILA trial in high-risk smoldering multiple myeloma, as well as advances in CAR-T and other evolving treatment strategies in the myeloma space. TRANSCRIPT Dr. Monty Pal: Hello everyone and welcome to the ASCO Daily News Podcast. I'm your host, Monty Pal. I'm a medical oncologist, underline medical oncologist, a professor, and vice chair of academic affairs at the City of Hope Comprehensive Cancer Center in Los Angeles. You're going to understand why I underlined "medical oncologist" there. I'm actually on the line today with two amazing hematologists. Today, we're going to actually explore treatments for high-risk smoldering multiple myeloma following the FDA's approval last year of daratumumab for the first-ever treatment of this indication. Now, this is based on the trial, and this represents a huge shift in our traditional watch-and-wait approach to active disease interception. We're going to consider whether this landmark trial published in The New England Journal translates to day-to-day practice. I think it does, and we'll certainly make an argument for that. And I'm so fortunate today to have two internationally acclaimed experts here in the conversation: Dr. Vincent Rajkumar, senior author on the manuscript, and Dr. Saad Usmani, also an expert in his own right in myeloma. Dr. Rajkumar is the lead investigator of the AQUILA study. He's a professor of medicine and consultant in the divisions of hematology and hematopathology at the Mayo Clinic in Rochester, Minnesota. He actually chairs the Myeloma, Amyloidosis, Dysproteinemia Program. He is also editor-in-chief of the Blood Cancer Journal. Dr. Usmani, he and I actually go way, way back. We actually did the AACR Molecular Biology in Clinical Oncology course, I want to say in 2006, so this is our 20-year anniversary, Saad. He's the chief of the myeloma service at the MSK Cancer Center and a professor of medicine at the Weill Cornell Medical College in New York. Saad, Vincent, welcome. Dr. Saad Usmani: Thank you so much for having me, Monty. Dr. Vincent Rajkumar: Yeah, thanks, Monty. A pleasure to be here. Dr. Monty Pal: Thanks. And just a quick note for our listeners, all of our disclosures are available in the transcript of this episode. First off, Saad, did I get that right? Was it 2006 when we did that course together? Dr. Saad Usmani: Yeah, 20 years. We are coming up to our 20-year anniversary. It's remarkable to have seen our careers move the way they have, Monty. Dr. Monty Pal: Oh my gosh. And for all the fellows who are on the line, that AACR Molecular Biology and Clinical Oncology course, it's sometimes overlooked. Wonderful primer on translational science. Okay, now we're going to get to the heart of the matter here, the AQUILA trial. So this was a study, Vincent, that you led. I wonder if you'd walk us through the primary endpoints in the study. What are we looking at in the AQUILA trial specifically? Dr. Vincent Rajkumar: Thanks so much. Again, as you mentioned, smoldering multiple myeloma has just been a condition that we watch and wait. And the first thing that I want to clarify here is that the AQUILA trial is looking at only a subset of smoldering multiple myeloma. That is the high-risk smoldering multiple myeloma. It was defined the way high-risk smoldering myeloma was defined at the time the trial was designed. It randomized 390 patients. One arm got daratumumab single agent in an attempt to delay progression to active myeloma and possibly prolong survival. And the other arm was the traditional observation. The primary endpoint, therefore, was time to active multiple myeloma. Other endpoints included time to when patients needed to start therapy for active multiple myeloma, which can vary based on physician judgment, and overall survival. Of course, response rate, complete response rate, and others were also endpoints. Dr. Monty Pal: That's interesting. And you know, I wanted you to riff a little bit on this definition of high-risk smoldering myeloma. Can you tell our audience how that's sort of evolved over the years? Dr. Vincent Rajkumar: Yes. I mean, if you step back, monoclonal gammopathy of undetermined significance has only a 1% per year risk of progression. Smoldering multiple myeloma, all comers have a 10% per year risk of progression. And over the years, trials have been done in the whole population, and then more recently, we felt we should really focus on the people with high-risk smoldering, defined as a 50-50 risk of progression in 2 years. That's like a 25% per year risk of progression in the first 2 years, which is a very high risk for the patient and something that would justify prophylactic intervention. And that definition initially was based on just high levels of monoclonal protein like more than 3 grams, the IgA subtype of myeloma, the suppression of uninvolved immunoglobulins. Others have used bone marrow flow cytometry markers, cytogenetics. Those combinations of factors were available at the time the AQUILA trial was designed, and a select combination was used. Later on, we found that we could match almost all of that in a very simple risk stratification using just the percentage of bone marrow plasma cells, the level of the M-spike, and the free light chain ratio, all three of which are available to all patients with smoldering at the time of diagnosis. So you don't need any special testing. So more than 20% plasma cells, more than 20 for the light chain ratio, and more than 2 grams for the M-spike. If someone has any two of the three, that is high-risk smoldering multiple myeloma according to the IMWG, but that definition, of course, came in 2020 after the AQUILA trial completed accrual. Dr. Monty Pal: That's interesting because this sort of flips the traditional paradigm where biomarkers get more and more complex as time goes on. Am I right in saying this sort of simplifies things a little bit? It uses standard laboratory or clinical parameters to gauge this category? Dr. Vincent Rajkumar: Absolutely. People were using suppression of uninvolved immunoglobulins, and those levels are not standardized, often vary by race. Also, the other aspect was the abnormal plasma cells on flow cytometry. Again, labs define it differently. So this makes it much more simple. But the IMWG also did a separate exploratory cohort within that paper where we added cytogenetics and we added scoring systems to improve on this further. So it simplified it for regular clinical practice and for like trials. But if you have a patient in front of you, the IMWG paper also has more complex scoring systems where you can take more than 20; 21 is more than 20, so is 51. And so, you can use the actual numbers that a patient has, additional variables like cytogenetics, and get a more refined estimate of what is the true risk of progression. Dr. Monty Pal: That's really helpful. Now, you told us about the primary endpoints, you've helped us define high-risk smoldering myeloma. Can you give us a sense of the top-line results from AQUILA? Dr. Vincent Rajkumar: Yes, I think the most important one was the primary endpoint, time to multiple myeloma, was at 5 years, the progression-free survival was 63% in the daratumumab arm compared to 41% in the observation arm. So, you know, approximately 60% of patients in the observation arm had already progressed by 5 years. And that number was about 40% for the daratumumab arm. We also looked at time to starting myeloma therapy, which is clinically actually quite meaningful because, you know, myeloma therapy means patients get a quadruplet for induction, they get stem cell transplant, they get endless maintenance, they get ongoing therapy virtually for the entire duration. So, preventing the need for myeloma therapy is in and of itself, I think, a major endpoint. And that at 3 years, 40% of people in the observation arm required full myeloma therapy compared to only 20% in the daratumumab arm. So there's a significant reduction in the risk of developing active myeloma as well as the need for myeloma therapy by using a time-limited 3 years of daratumumab single agent. Dr. Monty Pal: Perfect summary of the results. And maybe, Saad, I'm going to bring you into the conversation now. How does this sort of influence your day-to-day practice for smoldering myeloma? Is this something that you've incorporated for that high-risk subset? Dr. Saad Usmani: Thank you, Monty, and I agree. I think that's a really nice summary from Vincent. This study is very important for several reasons. It's actually the third clinical trial that has demonstrated that patients who are in the high-risk smoldering myeloma category benefit from an early intervention that delays the progression to active myeloma or to end-organ damage. And so having a nuanced discussion with our patients in the clinic becomes very important. Having this discussion around as an option becomes very important. And like Vincent said, when we look at that high-risk smoldering myeloma patient population, someone who has 22, 23% plasma cells versus, you know, 45, 50, you know, it's going to be a different discussion each time. But I think it's a very important first step. And I think this sets up the stage for us to design clinical trials where we can ask other questions on what would be better than daratumumab alone in terms of delaying progression in these patients. The other thing that I do want to highlight, and Vincent touched upon this a little bit, that the treatment in this clinical trial was for a fixed duration of treatment. So it was not forever treatment. This is maybe something that Vincent, you can even comment on a little bit more because the question we get after having this discussion is, “Okay, what do we do with patients who are going to be progressing to active myeloma?” Whether we can utilize anti-CD38 therapies for those. So Vincent, I would love your take on this too. Dr. Vincent Rajkumar: Yeah, I think, you know, the main philosophical change for me was previously, the thing was ‘don't treat’, and now for high-risk smoldering multiple myeloma, the question is, is daratumumab the best treatment or can we do something better? And those trials are thankfully ongoing. One of them has already completed accrual, isatuximab-len-dex versus len-dex. And another one is ongoing in ECOG, almost close to finishing accrual. And in the future, we'll be trying to see if we can use early intervention to even cure and prevent progression altogether. So we are in this phase where we have one approved regimen, one approved drug, and we are not sure whether we can improve on that. The question is, “is a myeloma-like therapy better than monotherapy” would be the next question, and then what would we do further beyond that? In this context, whenever we have patients like this, one of the questions that comes up, as Saad mentioned, is how does this affect newly diagnosed myeloma therapy if somebody has been treated for smoldering and things like that? How will they be considered for clinical trials? Would they be considered as relapse myeloma or still newly diagnosed myeloma? And those are important discussions for clinical trialists to keep in mind, but I think for clinical practice, your duty is to the patient in front of you. If they have high-risk smoldering myeloma and there's data that there's treatments that can delay progression significantly, delay the need for myeloma therapy significantly, that's the highest priority. We'll cross that bridge. There are so few patients going on clinical trials right now that if such a patient were to later on progress and wants to enter in a newly diagnosed myeloma trial later, years later, we can figure that out later. I feel like the most important discussion is what to do for that patient today. I still prefer a clinical trial if one was available. If one was not available, I'd prefer early intervention, but have an informed discussion with the patient because some of them may wish to delay therapy still. Some of them may have very borderline numbers that you want to watch them closely. Some of them may be having other comorbidities that prevent need for therapy. Some of them maybe have had the smoldering for a long time and you already know it's stable. So a lot of factors go in, and I think it's not a one-size-fits-all. Dr. Monty Pal: This is a terrific discussion, and you know, it sort of segues into maybe a question around biology. And this is something I was going to get to a little bit later, but Saad, I'm glad you brought it up. I'll liken it to the only thing I know, which is kidney cancer. So, you know, in kidney cancer, we use checkpoint inhibitors as adjuvant therapy. And there's this question of whether or not it breeds some resistance in the localized setting to ultimately what the patient might potentially be exposed to in the metastatic setting. Tell me your thoughts on this, Vincent, then maybe Saad separately. If you treat a patient with daratumumab in this high-risk smoldering setting, could it theoretically sort of limit options in the refractory setting now that we have regimens like DRBD that are kind of being utilized, or daratumumab with teclistamab? Vincent, I'll throw that to you first. Dr. Vincent Rajkumar: This is a great question, and it's usually asked when we've done the lenalidomide trials actually. We try to put the question back. If that was your concern, how would you actually solve it? Is it really biology that's going to answer that? Or is it a randomized trial? So the experiment has been done three times now where early intervention has been given. And if there was some detriment because of that, that would be reflected in the overall survival. In all three trials, there's no such detriment seen. In the first lenalidomide-dex trial, there was an improvement in overall survival. In the AQUILA trial again, the confidence interval doesn't cross one, and patients had better long-term survival on AQUILA, but certainly not less. We've also examined PFS2 data, and that doesn't seem to be affected. So yes, there is a theoretical concern, and that concern cannot be allayed for new treatments which we have not even tried, like tec-dara, and whether that effect would be there or not. But so far, I don't see it. And I think the onus is on proof of that in order to prevent people from getting early therapy. Dr. Monty Pal: Yeah. Saad, your thoughts on that? And before you jump in, I'll mention, we're kind of taking the same approach in kidney cancer, we're trying to really do studies to see whether or not, you know, immunotherapy rechallenge in these contexts, you know, really lends any substantial benefit. So far, the results have been interesting. I don't think we have enough numbers as yet to capture the impact of adjuvant therapy as it translates to metastatic, but I see so many similarities between the scenarios that you're facing in myeloma and what we're facing in RCC. Saad, your thoughts? Dr. Saad Usmani: Thanks, Monty. I'll go back to something that Vincent alluded to a few minutes ago about the way that we risk-stratify patients within smoldering myeloma. Right now, we are relying more on a disease burden-based stratification looking at the percentage of plasma cells in the bone marrow, the monoclonal protein, as well as the involved light chain versus the uninvolved light chain ratio. However, there are efforts underway to actually incorporate genomics into that schema and try to refine that definition of high-risk smoldering. And there have been two papers that came out in the latter half of last year. In fact. Dr. Rajkumar and I are co-senior authors on one effort where we can identify genomic myeloma in patients in precursor conditions. One of the key things that came out of that effort was that within the high-risk smoldering myeloma category, about 90% of the patients are genomically myeloma. So this whole debate of whether we need to intervene for those patients, I think, you know, we have sufficient biologic evidence that yes, we need to intervene for those patients. I think that the next real step, like Vincent stated, is how do we intervene in those patients? And those clinical trials kind of are ongoing. We will probably need to have more validation of those genomic models being incorporated, but that's what I see in the future. I wouldn't be concerned for the patients being seen today with that query about the disease biology evolving because if I'm seeing a patient today in March of the first quarter of 2026 and offering them monotherapy daratumumab in their high-risk smoldering situation for the next 3 years and then they progress to myeloma after another couple of years, we are talking about what would be the treatment options for them in 2031, 2032. So I think the field is moving so fast, we have a lot of novel therapies coming into that frontline setting rapidly, so our options at that time would be very different. So, you know, I just wanted to kind of set up the stage for saying, you know, our tools are getting better in delineating which patients will need that intervention. And then eventually, I think, you know, we'll have much better options for newly diagnosed myeloma patients at the time when they need it in the future. Dr. Monty Pal: Just absolutely brilliant, absolutely brilliant. I love that summary. I think that you're absolutely right in saying that, you know, you’ve got to think about what you're going to do for that patient sort of in the moment, what's going to optimize their outcome and agree that the landscape is evolving very rapidly. I'd be remiss, Saad, if I didn't ask you about something that I've been following in terms of your career trajectory. You've developed quite a reputation for your leadership in trials looking at CAR T-cell therapies for myeloma. Can you give us a sense of where that stands in broad terms? Dr. Saad Usmani: Certainly, Monty. I think the CAR Ts have slowly made their way from late relapse to early relapse. And now we have clinical trials that have completed accrual in the frontline setting comparing them to standard-of-care treatment for both older myeloma patients or transplant-ineligible patients, as well as younger transplant-eligible patients where we're actually trying to replace transplants with BCMA-directed CAR T-cell therapies. The nuance there would be we want to equal or better the survival outcomes that we've accomplished without compromising on the safety side of things for patients. Those therapies are moving into earlier lines. And more excitingly, you know, that's just the first wave of CARs. The next wave of CAR technology is coming, and it's going to be in vivo CARs where we may not need lymphodepleting chemotherapy, we may not even need as stringent regulatory nuances that we do for cellular therapies today. So, you know, I think the field is moving rapidly, and it's going to be a very interesting landscape to see over the next 5 to 6 years. Dr. Monty Pal: Yeah, you know, it's so interesting. I know in the solid tumor space, we're trying to replicate the success that you've had with CAR T and bispecifics, and I do see some light at the end of the tunnel. I'm seeing some really promising agents being developed, but clearly, we have so much to learn from our colleagues in hematology. Well, I have to tell you, this has just been a phenomenal conversation. Vincent, congratulations on your leadership of the AQUILA trial. Clearly, a big paradigm shift in the field. Saad, thank you for offering your expert insights and really giving us also a glimpse at the future of myeloma. Really appreciate having you both on the podcast today. Dr. Vincent Rajkumar: Thank you, Monty. Dr. Saad Usmani: Thank you so much. Dr. Monty Pal: And thank you... /episode/index/show/ascodaily/id/40686520

Navigating Therapeutic Advances in EGFR-Mutated NSCLC 03/19/2026

Navigating Therapeutic Advances in EGFR-Mutated NSCLC Dr. Monty Pal and Dr. Vamsi Velcheti discuss the evolving treatment landscape in EGFR-mutated non-small cell lung cancer, including landmark trials like FLAURA2, novel drug therapies, and the growing importance of ctDNA and MRD testing. TRANSCRIPT Dr. Monty Pal: Hello, and welcome to the ASCO Daily News Podcast. I'm your host, Dr. Monty Pal. I'm a medical oncologist and professor and vice chair of academic affairs at the City of Hope Comprehensive Cancer Center in Los Angeles. Today, I'm truly delighted to introduce Dr. Vamsi Velcheti, who's a professor of medicine and the chief of hematology-oncology at the Mayo Clinic in Jacksonville, Florida. We'll be discussing the expanding treatment landscape in EGFR-positive lung cancer and how to navigate the challenges of balancing treatment efficacy, toxicity, and patient quality of life in the EGFR-positive space. Just FYI, our full disclosures are available in the transcript of this episode. Vamsi, it's so great to have you on the podcast. Thank you so much for being here. Dr. Vamsi Velcheti: Thank you, Monty. It's a pleasure to be here with you. It’s a really exciting topic and there are a lot of updates in the EGFR space. Dr. Monty Pal: So, I'm going to need your help with this because I'll be honest with you, I see very little lung cancer, if any, in my practice. I'm pretty much exclusively kidney cancer these days. I'm coming on 20 years at City of Hope now, and I still remember when trials like were presented with, you know, platinum doublets. And, of course, the field has changed a lot since then. But tell us a little bit about the first-line landscape, and I think just for the sake of time, we're going to stick with EGFR-positive disease here. What does it look like these days? Dr. Vamsi Velcheti: Monty, the foundation of care remains the third-generation EGFR inhibitors. These are selective EGFR inhibitors, like osimertinib. We've had an evolution of the development of these TKIs. Like, you know, we had the first-generation, second-generation, not-so-selective EGFR inhibitors. Now we have mutant-selective EGFR inhibitors in the clinic, and they're doing a really good job. And these are quite effective in patients who have classical activating mutations. But the reality is that these have not been transformative. These agents have fundamentally changed the response patterns, excellent CNS penetration, and very good tolerability profile. However, we don't see a lot of durability in terms of the response. So, what's different today is now there have been several trials in combination with these third-generation EGFR inhibitors that have really laid the foundation of how we kind of think about EGFR-positive disease. At the high level, there are a lot of challenges to selecting the patients for these combination-based modalities. I'm assuming we'll be talking more about these different trials and different approaches. Some of these combination-based strategies have really moved the needle in terms of improving overall survival and really improving long-term outcomes and durability in our patients. Dr. Monty Pal: And we are going to get into the weeds on this in just a moment. But I did kick off this podcast talking about chemotherapy, ECOG 1599. It does seem as though chemotherapy is still a component of management in advanced non-small cell lung cancer. So, can you tell us about, perhaps first, you mentioned osimertinib, you know, some of these next-generation EGFR inhibitors. Tell us about the role of chemo plus osimertinib. Dr. Vamsi Velcheti: That's exactly where I was going with the combination-based strategies. You know, we first started off with our earlier trials in the EGFR space evaluating the question of, are targeted therapies, are these highly effective, third-generation, EGFR-selective inhibitors, superior to platinum-doublet chemotherapy? And we've had multiple trials demonstrating that, like the trial and in the past with second-generation EGFR inhibitors like erlotinib and gefitinib and afatinib. So, we know that these TKIs actually perform better than platinum-doublet chemotherapy. Now, we have a large, global, phase 3 trial data from the trial, which looks at the question, "Hey, you know, osimertinib is better than chemotherapy, platinum-doublet chemotherapy. Can we do even better by combining osimertinib with platinum-doublet chemotherapy?" So, FLAURA2 answered that question. This is a large, phase 3 trial, and it's a positive trial with improved durability of disease control and improving overall survival with combination with chemotherapy. So, it's a very important and landmark trial, and essentially combining osimertinib with a platinum-based chemotherapy improved responses, deepened responses, and improved overall survival and really changing the disease trajectory. And this strategy is definitely compelling, especially in patients who have certain clinical high-risk features like, you know, patients who have high disease burden or patients who are sometimes having rapid disease progression early on osimertinib, especially with patients who have a lot of visceral disease burden. So, intensifying treatments up front could alter the natural trajectory of the disease. Dr. Monty Pal: So, you sort of alluded to this in that last part there, but is that kind of how you in clinical practice select? Is it based on, you know, visceral involvement? Is it based on rapidity of disease where you think about adding chemotherapy to osimertinib? Maybe you can give us the corollary. Which patients do you just use osimertinib alone in, for instance? Dr. Vamsi Velcheti: Definitely, there are some patients who have low disease burden and they have the classical mutations, like an exon 19 deletion. And these patients, especially if they don't have a lot of disease burden, they don't have CNS involvement, there may be a subset of patients who could just do fine on osimertinib of course, with close monitoring of the disease. I guess we'll get into that later, how do we do that with either ctDNA or like closer imaging or both. So, there may be some opportunity to kind of escalate patients' treatments based on certain clinical characteristics or radiographic characteristics or certain biological characteristics informed by ctDNA or other approaches. Dr. Monty Pal: No, that's interesting. And you're right, we will chat about ctDNA in just a bit. But before we get there, I think one of the big agents that has really sort of come to the fore in advanced non-small cell lung cancer is amivantamab. I've heard a lot about this in the context of even kidney cancer because in certain subsets, I'm interested in MET-directed therapies and so forth, right? So maybe tell us a little bit about the mechanism of amivantamab first, and then maybe tell us about this pivotal trial where it's combined with lazertinib. Dr. Vamsi Velcheti: So, the MARIPOSA trial compared lazertinib alone with amivantamab plus lazertinib. And this trial demonstrated overall survival advantage, and there were key differences in terms of tolerability and the safety of amivantamab, which is an EGFR and MET bispecific, and there were certain kind of unique toxicity profiles that make it a little different than the intensification approach with chemotherapy through the FLAURA2 trial. So, there's a trade-off in terms of the toxicity profile. It's a different agent and a different management protocol in terms of dermatological toxicity management that clinicians need to be comfortable with. And also, there are certain unique issues in terms of amivantamab; there's a higher rate of infusion-related reactions, there's an increased risk for edema and VTEs because of amivantamab. Certainly a different toxicity profile, different management paradigm there in terms of longitudinal care of these patients requiring dermatological care and like, you know, close monitoring and prophylaxis VTEs. But having said that, definitely it's a different strategy, and it kind of changes the biology and the natural history of the cancers, and we do see some durability of responses that we see with the MARIPOSA. So, it's certainly a great alternative, at least for some patients. Dr. Monty Pal: That was a great overview of MARIPOSA. Now comes the really difficult question, which is, how do you choose between the two? You have these two great options, right, for EGFR-positive patients. You've already highlighted some of the distinctions in terms of toxicity. I think the audience is well aware of the side effects of chemo-doublet, perhaps even the EGFR-based therapies. Amivantamab is quite new. Give us a sense of how you in clinical practice decide between the two potential options here. Dr. Vamsi Velcheti: Yeah, I think that's the big challenge. I think these are two independent strategies that have evolved through the phase 3, and both of them have demonstrated overall survival benefit. So, the way I think about this is in three dimensions, right? Like, the disease biology, the patient priorities, and feasibility of care delivery. So, when I talk about the disease biology, you know, the mechanism is very different, and MET is a very dominant driver of disease in EGFR-altered patients and it's a significant mechanism of resistance, acquired resistance to TKIs. So, certainly I think there's a patient population that could benefit from a MET-directed therapy up front. However, we don't have great data to kind of really demonstrate how using amivantamab in the front line is going to change that. And are there like perhaps like some patients who we could identify who would benefit from such a strategy? Very recently, there have been some approvals in the second-line setting in lung cancer, not in the EGFR space, but like in generally in lung cancer, with the MET ADCs, and those drugs are approved with a companion diagnostic, which requires MET IHC testing. So, what has happened, at least in large academic practices and also I think in the community now, they have been checking for MET IHC expression more routinely in lung cancer. What we have been doing in our institution is we have been doing MET IHC as a reflex for all patients with EGFR, not just EGFR, but all non-small cell lung cancer patients. What that has done is now, like, we have been increasingly testing patients with EGFR for MET. And there's clearly a subset of patients who have de novo MET expression and a high MET expression. And those patients, I've been kind of like preferentially treating them with the MARIPOSA regimen. But again, I have to caution the audience that we still don't have data that MET IHC is going to help us make those decisions, whether it's better than like a FLAURA2 regimen. But however, in the second-line setting in the trial, we know that MET is a very powerful predictor of response to amivantamab. We really need more data there, but that's what I have been doing in my practice. But also, there's a lot of patient preference here. Like, there are some patients who don't want chemotherapy, and they want a non-chemotherapy approach. So, certainly there are some patients who prefer to have amivantamab. And now with the amivantamab, the subcutaneous version, the infusion reactions and the logistics of actual administration of amivantamab are more favorable with the subcutaneous approval. So, those are some of the elements that we need to take into account. Dr. Monty Pal: Well, I want to hone in on that because this subcutaneous administration route has been a big debate that I've seen on social media. Tell us, how much easier does it actually make the amivantamab experience? Does it cut down on the rash? Is it just infusion reactions? What's been your clinical experience? Vamsi Velcheti, MD: So, the subcutaneous administration of amivantamab has definitely improved the infusion reaction issue. Very rarely patients have infusion reaction now with the subcutaneous injections. And also, the infusion time is much, much shorter. Like we don't need a lot of infusion time, which is sometimes a challenge in busy infusion clinics. We need to take that into account. As far as the impact of the subcutaneous formulation on dermatological toxicity, we haven't really seen significant difference in terms of the intensity or rates of dermatological toxicity with subcutaneous. The benefits are really with the infusion reaction, the ease of administration. And interestingly, in the trial, it also seems to be, even though this was not the primary endpoint of the study, there seems to be some suggestion that the subcutaneous amivantamab seems to have improved OS compared to the IV amivantamab. We don't really understand why, but that's a finding from the trial that's very intriguing. Dr. Monty Pal: That is really fascinating. I'm kind of curious to see how that's going to pan out. I'm going to shift gears a little bit here. And, you know, as we sort of close, I wanted to talk a little bit about biomarkers. I mean, this is obviously not a lung cancer-specific issue. It's something we think about across the board. But what I will say is that there are certain commonalities, and in bladder cancer, we think a lot now about ctDNA. But you've been way ahead of the game in lung cancer. Tell us how you guys use ctDNA, maybe both from the standpoint of monitoring for mutational status, but if you can, maybe offer some insights into some of these new MRD tests that are available too. Dr. Vamsi Velcheti: Yeah, it's rapidly evolving. Certainly, I think in the lung cancer space, you know, this has really kicked off in the lung cancer space with incorporating ctDNA into the workflow. Of course, you know, like baseline evaluation, we still kind of heavily rely on tissue genomic sequencing. But as you know, with targeted therapy, a lot of these patients have disease that evolves over time, and changes in terms of mutational pattern driving acquired resistance is a major issue across different molecular subtypes. And especially so in EGFR, when there are certain actionable opportunities associated with that transformation. So, we need to kind of have like a longitudinal snapshot of how we monitor these patients. So, the ctDNA has come to be like a tool that has now come to the forefront of clinical workflow, and almost all my patients who are having disease progression have ctDNA for kind of evaluating for resistance and informing treatment decisions, especially in EGFR. But having said that, there are a lot of challenges in terms of using ctDNA as a tool for monitoring. There are a lot of different types of assays and different platforms, and being able to use this as a quantitative tool that would be used along with the CT scans that we routinely use in clinical practice has been a challenge. And I think I would love to hear your perspectives as well, Monty, about how you're thinking about that in bladder and other disease contexts. But having said that, I think there's a lot of opportunity to incorporate ctDNA and MRD assays into clinical decision-making. Right now, in terms of clinical trials and clinical development, there have been some very interesting trials that are currently ongoing, especially in the EGFR space. We know that patients who clear ctDNA, based on some retrospective data and also like some retrospective-prospective data from trials that have already read out, that patients who clear ctDNA early with target therapy tend to do much better. They have a longer durability of response. There may be a subset of patients who have, even though they're having radiographic response, they have persistent ctDNA after a certain time point of initiation of targeted therapy. Those patients may require escalation of therapy. We don't yet know. I can't recommend that as a standard right now because we don't have clinical evidence to support that. But however, some of the clinical trials, like the trial that's being done right now, that's actually completed enrollment, we'll hopefully see the results very soon. So, there is an emerging thought that instead of intensifying treatment for all patients with EGFR, there may be a population that may be just fine with frontline osimertinib monotherapy and introducing the intensification strategy at the time of emergence of MRD or progression on ctDNA before radiographic progression. So, there are a lot of adaptive molecular response criteria that we are kind of exploring in clinical trials that could inform how the future is going to look like for EGFR and other perhaps targeted therapies as well. So, it's fascinating, and I think there's a lot of opportunity there. Dr. Monty Pal: You know, you asked for my perspective. I actually think that what you highlighted there is the most interesting opportunity for ctDNA: the ability to de-escalate therapy. In terms of drug development, we've done so much to bring new therapies to patients, and now it's a bit of an embarrassment of riches, but the downside is that I feel like we tend to overtreat a lot of patients in the clinic. So, I definitely view MRD, you know, some of these other ctDNA techniques with methylation and so forth that may not be sort of tumor-dependent or bespoke could be incredibly, incredibly helpful. You touched on sort of the future, right, in this last section here with biomarkers. But give us a sense now in terms of novel drug therapies in the EGFR space. What are you most excited about moving forward in 2026 and beyond? Dr. Vamsi Velcheti: Yeah, I think there's a lot going on in this space, and not just this space, but across lung cancer and others as well. Like looking at the next generation of targets for ADCs. And I think a lot of these have to do with…so far in the drug development space, as you know, the improvements in clinical outcomes has been very incremental. So, we really need to make that big leap. And I think the big leap is not going to come from, in my opinion, from the next ADC, but it's going to come from how we tailor treatments and how we monitor disease better and how do we kind of incorporate the next treatment earlier and not wait for the radiographic progression. So, there's a lot of opportunity there to integrate biomarkers and dynamic biomarkers into clinical trial design and incorporating the recent advances in terms of drug design. You know, we have a lot of assets in the EGFR space, the next-generation EGFR inhibitors that are kind of designed with resistance in mind and rational combination, knowing when to introduce those combinations is also equally important. So, there's a lot going on, really exciting times to be in drug development. The one thing that I really hope will come to the forefront in drug development, not just for lung cancer, but all disease groups, is to kind of really be thoughtful about how we incorporate these really cool molecular monitoring tools and creating a composite score with imaging to be able to like really design the next generation of clinical trials. Dr. Monty Pal: You're so spot-on with that. I definitely think that we're getting to this point where, you know, we could think about the next BiTE, the next CAR-T, the next ADC. But, you know, maybe it's time for us to start really honing in on appropriate applications of these drugs, honing in on the right dose and what have you, because I definitely see some issues there. Vamsi, this has just been terrific. I really want to thank you so much for sharing your fantastic insights with us today on the ASCO Daily News Podcast, and I really appreciate all your efforts to move the field of lung cancer forward. Dr. Vamsi Velcheti: Thanks, Monty. I really enjoyed the conversation. Dr. Monty Pal: Yeah, this was terrific. And thanks to our listeners as well.

Highlights From the 2026 ASCO GU Cancers Symposium 03/05/2026

Highlights From the 2026 ASCO GU Cancers Symposium Dr. Monty Pal and Dr. Andrea Apolo discuss practice-changing studies and other novel approaches in bladder, kidney, and prostate cancers that were presented at the 2026 ASCO Genitourinary Cancers Symposium. TRANSCRIPT Dr. Monty Pal: Hello and welcome to the ASCO Daily News Podcast. I'm your host, Dr. Monty Pal. I'm a medical oncologist, professor and vice chair of academic affairs at the City of Hope Comprehensive Cancer Center in Los Angeles. And today is super exciting, we're highlighting key abstracts that were presented at the 2026 ASCO GU Cancers Symposium, and I'm just delighted to be joined by the chair of this year's meeting, who is also a dear friend, Dr. Andrea Apolo. Dr. Apolo serves within the Center for Cancer Research at the NCI as head of the Bladder Cancer Section, and she is also acting deputy chief of the Genitourinary Malignancies Branch. Welcome, Andrea, it is so great to have you on the podcast. Dr. Andrea Apolo: Oh, thank you so much for having me. What a great ASCO that we had, it is really exciting, lots of really great data. So I look forward to chatting about it. Dr. Monty Pal: Excellent. And you know, our full disclosures are available in the transcript of this episode in case our listeners want to have a peek. The theme of this year's GU meeting was “Patient-Centered Care: From Discovery to Delivery.” I love that theme. And really, this is one of the most competitive meetings out there, more than 850 abstracts being presented on high-impact science. Andrea, I just wanted to get right into it and dive into what I think we both felt were some of the most exciting abstracts of the meeting. And the first of those is one that I know is near and dear to your heart, being a bladder cancer expert yourself, and that is the study presented by Matt Galsky. Can you give us a flavor for what that study entailed and some of the key results? Dr. Andrea Apolo: Yeah, I think this was kind of the missing study that we have been waiting for since we saw the data in metastatic disease in the frontline setting. We wanted to know how well this combination would work in muscle-invasive bladder cancer patients. And we saw half of that puzzle, you can say half of the piece of the puzzle, when we saw the data at ESMO, the data in patients that were cisplatin-ineligible. And then now we are getting the full story with patients that are platinum-eligible, cisplatin-eligible, with the data. So that study randomized patients to receive chemotherapy, so different than the EV-303 where the patients were randomized just to receive the radical cystectomy. These patients were randomized to receive neoadjuvant EV plus pembro and then adjuvant EV plus pembro versus neoadjuvant gemcitabine and cisplatin with no adjuvant component to the control arm. So I think this is a really, really important study. Dr. Monty Pal: And share with us some of the results because this in my mind is definitely practice-changing. This is one of those studies that I think you walked into the office on Monday and you are like, “Okay, this is what I am doing now,” right? Dr. Andrea Apolo: Yeah. So the study was positive. The primary endpoint was event-free survival, and it met the primary endpoint. The secondary endpoint of overall survival was also met. So really, really great results. Consistent with what we saw with EV-303, the median event-free survival was not reached for the EV plus pembro arm, and it was 48 months for the patients receiving gem-cis. And then looking at the 24-month estimated event-free survival, it was 79% for the EV plus pembro and 66% for the chemo, the gem-cis arm. And that was a hazard ratio of 0.5. So that is really exciting. That is the event-free survival. And then the overall survival, the medians were not reached for either arm, but when you look at the 24-month estimated overall survival, it was 87% for the EV plus pembro versus 81% for the gem-cis, and that was a hazard ratio of 0.65. So very positive study. And then another question that we had was the pathologic CR rate. Very consistent with what we saw with the EV-303, the pathologic response rate was about 56% for the patients that received EV plus pembro and about 32%, 33% for the patients that received gem-cis. So very consistent with the findings that we have been kind of seeing in phase 2 studies, and this is a pT0N0, so that is important. Dr. Monty Pal: So Andrea, you know, I think that the big question in folks' minds is at this point, we see the data from , cis-gem-durva, we have now seen this data. Put it into context for us. Is there a patient in this day and age who maybe shouldn't get IO altogether, who should maybe get the NIAGARA regimen as opposed to EV-pembro in this context? What are your thoughts there? Dr. Andrea Apolo: Now, that is a great question. I would say with this data, it is very enticing to give EV pembro to our patients in the perioperative setting, and for that to be the new standard of care for all patients, regardless of cisplatin eligibility. So similar to what we saw with EV-302 really changing the standard of care in the frontline setting, I think these two studies, the EV-303 and the EV-304, change the standard of care for patients with muscle-invasive bladder cancer in the perioperative setting, and this should be the new standard of care if the patients don't have a restriction to receiving an immunotherapy. Dr. Monty Pal: I totally agree with that assessment. It is great to hear it from the expert's mouth as well. Thanks a lot for that, Andrea. The next abstract I wanted to tackle is one that is, I would say, near and dear to my heart because I know these folks really well. It is led by the SWOG group, and this is . The number there for the audience gives you a sense of how long the study has been running for. The 16 prefix means it is something that we kicked off back in 2016. So this study is really 10 years in the making, right? So Rob Svatek presented this data. It is interesting, right, because it addresses this issue of the BCG (Bacille Calmette-Guérin) shortage, right, where we have needed to sort of rely potentially on other alternative sources or regimens and so forth. Tell us about this trial, Andrea. Dr. Andrea Apolo: This is one of my favorite studies. We talked about putting it in the main oral abstracts, but we put it in one of the educational sessions that talked about non-muscle-invasive bladder cancer because we thought that would be the best audience for it. But it doesn't take away from how important this abstract is, and the tremendous effort that went into the study. Almost a thousand patients enrolled. I think 984 were eligible to enroll in this study. So it is a very high enrolling, randomized, cooperative group study in high-grade non-muscle-invasive bladder cancer. And really the study was designed to address two questions. One is the BCG shortage and can we use a different strain, Tokyo versus TICE? And whether there is a priming effect if you gave intradermal BCG to patients with non-muscle-invasive bladder cancer, can that enhance the effect if you gave it a little bit earlier? I think the study is really important, and it met its primary endpoint, which was it is not inferior to TICE. The findings were really terrific in terms of the outcomes. Numerically. When you look at the endpoint, it looked like the Tokyo strain was as good, if not maybe a little bit better, but not statistically significant than the TICE. And then they broke it down by carcinoma in situ, they broke it down by papillary tumors, and the Tokyo strain was non-inferior in both of those instances. But interestingly, the intradermal BCG did not change outcomes. There was really no priming effect, which was really backed up by pre-clinical data that there would be, but there wasn't a priming effect when the intradermal BCG was given in the Tokyo strain. So that was a really, really interesting finding. But a great study, really important outcomes in the field for non-muscle-invasive bladder cancer. Dr. Monty Pal: Totally. And it just seems like we can't get away from BCG, right? You know, as hard as we try, I mean, I appreciate the studies that sort of build on it that are emerging right now, but it seems like BCG at least for the foreseeable future is kind of here to stay, right? Dr. Andrea Apolo: It works. It is one of the most effective treatments we have for non-muscle-invasive bladder cancer. So, you know, I think it is here to stay and, you know, we need to find alternatives in terms of strains so we don't deal with this shortage that we have been dealing with for so many years now. Dr. Monty Pal: Yeah, indeed. Moving on to some of the other highlighted studies from the meeting, you had mentioned the EV-303 data, so we probably don't need to rehash that study design in much detail. But there was also a rapid oral abstract presented by Dr. Ullén that I think is of interest here, right, that really hones in on pathologic outcomes and DFS from that trial. Do you mind just outlining that for our listenership? Dr. Andrea Apolo: This is the , also known as the EV-303 study. This is a follow-up to the EV-303 data looking at the pathologic response rates, looking at the downstaging effect, looking at the surgical margins after treatment with the neoadjuvant EV plus pembro in the 303. Now, remember in the 303, patients got three cycles of neoadjuvant EV plus pembro and then six cycles in the adjuvant setting. A little bit different than the 304, where they got four cycles, which is really kind of the standard in the neoadjuvant setting, and then five cycles in the adjuvant setting. So still a total of nine cycles. But in the 303, the treatment arm had no systemic therapy, so it was just radical cystectomy. And they looked at the negative margins that you get with the EV plus pembro treatment, which was 92.6% versus 79% with patients receiving just the surgery alone. And then the pathologic CR rate, there was more follow-up on that, it was 57% for the patients receiving EV plus pembro, and as we would expect, about 9% for the patients that just went on to surgery alone because you can achieve a pathologic response rate with TURBT alone. Then they looked at the pathologic downstaging, so anything less than a pT2, and that was 66% in the patients that received the EV plus pembro. So very interesting findings, and it is also really just nice to have now the EV-304 data, like I was saying, there were two pieces of it, the cisplatin-eligible and the cisplatin-ineligible, and just to have those contemporary controls are really important. How did the cisplatin-ineligible do versus the cisplatin-eligible patient in terms of the event-free survival and in terms of the overall survival? So I feel like now we have all of this data that we can kind of put together in the perioperative setting and we can really inform our patients a little bit more about their outcomes depending on whether they are cisplatin-eligible or not, which you know cisplatin-ineligible patients often just, they are sicker, they may have obstruction, their tumors may be larger, they just tend to be a more delicate population than the cisplatin-eligible patients. So not surprisingly, you know, we see that in the EV-303 the disease-free survival for the patients is pretty poor. So the disease-free survival that was reported for this follow-up of the specific abstract was 23.6 months for the patients that just got surgery, and it was not reached for the patients that had the EV plus pembro, and that was a hazard ratio of 0.37. Dr. Monty Pal: Excellent, excellent distillation. So Andrea, in the interest of time, I mean, we could probably talk about bladder cancer forever, but I am going to move us on to the subject of kidney cancer. We have two late-breaking abstracts, , which looked at lenvatinib and belzutifan versus cabozantinib in the advanced setting, and then we have an adjuvant study, , that looked at pembrolizumab with or without belzutifan in the adjuvant setting. Both studies positive. One for progression-free survival, the other for disease-free survival. Both I think making a big dent in how we treat kidney cancer. Can you tell us a little bit about that? Dr. Andrea Apolo: Yeah, we have been waiting for these trials for a long time. So one of the things that we have been talking about at GU ASCO is to have plenary sessions. And if we would have had a plenary session, these two abstracts would have been part of it because they are important data, really big studies where we are trying to improve the outcomes of our patients with kidney cancer. So the first one, the LITESPARK-011, like you said, this is for advanced renal cell carcinoma, clear cell renal cell carcinoma, where we really don't have a standard of care after IO therapy, right? So we give IO-IO, we give VEGF-IO, but we don't really have a good standard of care. We usually give monotherapy TKIs. So the combination of belzutifan and lenvatinib versus what a standard of care is, cabozantinib, is really an important question to ask. And you know, this is a pretty large study, about 750 patients were randomized. And belzutifan plus lenvatinib demonstrated an improvement in progression-free survival and overall survival versus cabozantinib, but not overall survival, at least not yet, is what the authors are saying. So for the progression-free survival, the hazard ratio was 0.7 and it was 14.8 months for the combination, belzutifan plus lenvatinib arm versus cabozantinib, which was 10.7 months. So I think that is significant. And for the overall survival, it did favor the combination again with a hazard ratio of 0.85. The median was 35 months versus 28 months for the monotherapy cabozantinib, but it did not reach statistical significance. And the authors said that this will be further tested at a final analysis, these were the interim results. And for the overall survival, the overall survival was 53% for the combination versus 40%. This is significant. And the CR rates were lowish for both of them, it was like 5% for the combo and 1% for cabo monotherapy. So I think that the findings are important because we don't have a standard of care. And although there is no survival benefit, there was a trend. So I think this could be considered in patients that are fit, a treatment option for these patients in the later line settings. Dr. Monty Pal: Great points. I mean lots of great discussion around toxicity as well as efficacy. I mean certainly this is a regimen that may not be suitable for every patient in my portfolio, but certainly one to consider. Now Andrea, let's shift focus to LITESPARK-022, the adjuvant trial that I mentioned previously. So this is again looking at pembrolizumab with or without belzutifan, met the primary endpoint of disease-free survival. What are your impressions there of the data? Dr. Andrea Apolo: Yeah, the data looks great. And this was a really large study, 1,800 patients were randomized, and the study met the primary endpoint of disease-free survival, benefiting the combination of pembro plus belzutifan. And that is really terrific. The medians were not reached for either arm. And in terms of the overall survival results, also the medians were not reached, but the hazard ratio was 0.78 and did not reach a statistical significance. So there was again a statistically significant improvement in disease-free survival for the combination of pembrolizumab plus belzutifan, but not an overall survival benefit. So I guess, Monty, you know, we can kind of talk about what that means. There was a lot of discussion about belzutifan and some of the side effects, specifically anemia and managing anemia in this setting and requirements for transfusions. Generally, the authors said it was well tolerated, but we know that combination studies do have more toxicity. So it may be a select group of patients again, similar to the advanced setting, where we opt for a combination, possibly until we see more follow-up data in terms of the overall survival. Dr. Monty Pal: I have to agree with you. You know, in my group, we have been talking about a lot of pembrolizumab-based studies that are running right now, some through the NCI, some, you know, our own sort of homegrown investigator-sponsored trials, and you know, I think for the foreseeable future we are comfortable just maintaining pembrolizumab. Things might change if, for instance, we ultimately see a survival advantage emerge, but I just have my own personal doubts around that, that will be interesting. Okay, so now we are going to move to the last disease category that we are going to cover, which is prostate cancer. So there, we have the long-awaited results from the study. These are the final OS results from this trial looking at enzalutamide with or without radium-223 in metastatic castration-resistant prostate cancer. So Andrea, would love to get your perspectives on this. Dr. Andrea Apolo: Yeah, so this study had been presented before and we had seen positive results for the combination of enzalutamide and radium with some interim overall survival results also showing a benefit. But like you said, these are the final results with a median follow-up of 58 months. So it was really nice to see the final results. And with the combination of enzalutamide and six cycles of radium, it did show an improvement in overall survival with a hazard ratio of 0.76. The median overall survival increased from 32.6 months to 38.2 months with the combination. So that is really great. There was some crossing over of the overall survival curves around 18 months was still seen. And again, there was also an improvement in the rPFS with a hazard ratio of 0.71, and the median rPFS improved from 16.4 to 19 months with the combination. So, you know, we have been awaiting the final results, but we kind of knew a lot about the benefits of the combination. And it is something that is kind of slowly trickling into the community in terms of adapting it and using it. There is more buzz now about it and I think these overall survival results will hopefully shift the community into incorporating the combination in these patients. Dr. Monty Pal: Brilliant. So well said. I mean, Andrea, congratulations on a terrific meeting. You have really done it again. Incredible, incredible output from this year's ASCO GU. I just want to thank you for joining us on the program today. Dr. Andrea Apolo: Oh, thank you so much for having me, Monty. It was really a joy to work with the ASCO team and with all the investigators and the Education Committee and the Scientific Committee. Everyone was really outstanding. So to me it was an honor to be part of this meeting, and I am so happy that it was so successful and really presented some amazing data that I think will be practice-changing to our patients.

Personalizing Treatment in Head and Neck Cancers 02/19/2026

Personalizing Treatment in Head and Neck Cancers Dr. Monty Pal and Dr. Ari Rosenberg discuss the evolution of treatment strategies in head and neck cancers, including the challenges of treating both HPV-positive and HPV-negative disease and the emergence of blood-based biomarkers to advance personalized therapy across different subtypes. TRANSCRIPT Dr. Monty Pal: Hello and welcome to the ASCO Daily News Podcast. I'm your host, Dr. Monty Pal. I'm a medical oncologist, professor, and vice chair of academic affairs at the City of Hope Comprehensive Cancer Center in Los Angeles. Today, we're going to explore the evolving landscape of treatment strategies in head and neck cancer management, including locoregionally advanced head and neck squamous cell carcinoma, which happens to be on the rise in United States, in part due to spike in HPV-mediated oropharyngeal cancers. We're also going to discuss the emerging strategies of using blood-based biomarkers to really advance personalized therapy. Joining me for this discussion is Dr. Ari Rosenberg. He's a medical oncologist focused on head and neck cancer, and he's an associate professor – congratulations on the recent promotion – at the University of Chicago. The University of Chicago has really produced luminaries in this field, Dr. Rosenberg included. I've had the pleasure of getting to know Dr. Ezra Cohen over the years, who really had his grounding there, and of course Everett Vokes, former ASCO President. I'm really looking forward to this conversation, Ari. Thanks so much for joining us. Dr. Ari Rosenberg: Thanks, Monty. Thanks for the invitation. Dr. Monty Pal: You got it. And just a quick note for our listeners, our full disclosures are going to be in the transcript at the end of this episode. So let's start with the basics, if you don't mind. So, head and neck cancers are very diverse and they're challenging, right? In the sense that they're near vital organs, the treatments, you know, as we all saw during fellowship, if not now in clinical practice. They can really have such a major impact on vital organ function, speech, swallowing, et cetera. Can you just comment on head and neck cancers that are on the rise in the U.S.? I alluded to this briefly. Particularly, we've heard this in the context of colorectal cancer and so forth. Are you actually seeing younger adults being affected by this? Dr. Ari Rosenberg: Yeah, thanks for that. The vast majority of head and neck cancers are head and neck squamous cell carcinomas, as I'm sure many of the listeners recall as well from fellowship or their current training. And as you alluded to, the organ function, long-term and functional quality of life outcomes are quite important, particularly in the context that these develop in high value real estate, parts of our head and neck area that we use for speaking, swallowing, all sorts of other essential functions as well. As you also alluded to, we think of this in two different particular subtypes of head and neck cancer. The historical head and neck cancer from 50, 60 years ago was almost exclusively related to carcinogen exposure, tobacco, alcohol use, and that subtype of carcinogen-induced head and neck cancer has been slowly declining. However, over the last now several decades, we've been seeing an increase in primary oropharyngeal squamous cell carcinoma, mostly tonsil, base of tongue. These are attributable to HPV, human papillomavirus exposure. And that's now the majority of the head and neck cancers that we tend to see in our clinic. As you also alluded to, these have very different prognoses as well. HPV-related head and neck cancer has a much more favorable prognosis where much of the interest has been in can we de-intensify to optimize long-term function? But then the non-HPV-related head and neck cancer, or what we call HPV-negative head and neck cancer, continue to be very, very challenging. We only managed to cure about half of these folks, with many of these patients developing the current disease. These patients, in addition to being difficult to treat, also have major impacts both in terms of the treatments they undergo as well as their disease that can impact their function and quality of life. And you hinted at this a little bit, but we have been seeing an increase in younger patients with HPV-negative head and neck cancer as well, which is quite concerning. Younger patients, oftentimes never smokers, never drinkers, who are developing non-HPV-negative head and neck cancer. And that's been a little bit of a more recent trend that we've been seeing as well. So, definitely a lot of work to be done to optimize and improve outcomes across all of these different head and neck cancer subtypes. Dr. Monty Pal: I mean, I'm just curious, you know, in the context of colorectal cancer, one of the things that we talk about is the potential role of the microbiome driving some of these young-onset cancers with, you know, perhaps there being an impact on, for instance, inflammation and the gut and what have you. Tell me about head and neck cancer. Is this anything known as to why younger patients might be getting diagnosed with non-HPV type cancers? It's odd to me. Dr. Ari Rosenberg: Yeah, it's a great question. A lot of people are working on it. I think we folks have hypotheses, but it hasn't totally panned out exactly what's going on there. It does have a little bit more of a tendency towards women, whereas historically head and neck cancer is much more common in men than it is in women. But lots of people working on that, whether it's related to chronic inflammation, whether it's related to the microbiome. Whether it's related to dental exposure, dental work. So, a lot of folks trying to parse that out because I agree with you, it needs to be identified alongside improving treatment paradigms for these patients, the young ones and the older patients as well. Dr. Monty Pal: Interesting, interesting. You know, one of the phenomena that was sort of coming around when I was in training 25 years ago was this role of sort of induction therapy for head and neck cancers. And of course, it's really come full circle now to include checkpoint inhibitors and so forth. Tell me a little bit about this and how you apply it, maybe in an HPV-mediated context, maybe in a non-HPV context. Dr. Ari Rosenberg: Yeah, absolutely. Induction chemotherapy, as you alluded to, or neoadjuvant chemotherapy, depending on what the locoregional treatment approach is. Similar to other cancer types where systemic control early on has many potential advantages in this setting. Now, in head and neck cancer, even though induction chemotherapy is quite active in head and neck cancer, both HPV-positive and HPV-negative with pretty good response rates. A survival advantage for all comers with local regionally advanced disease remains unproven. There's been two randomized trials, both underpowered, but essentially did not show a survival advantage, showing that induction chemotherapy for all patients with locoregionally advanced and neck cancer can't be justified for a survival advantage. That being said though, there remains a number of potential advantages of giving induction or neoadjuvant chemotherapy, of course, improving systemic control and debulking the disease early on has potential advantages, and predicting the responsiveness to subsequent radiation treatment. We know for some time in head and neck cancer that the percentage of shrinkage or the response to induction chemotherapy actually predicts outcome related to radiation as a dynamic biomarker where response can be used to select patients, for example, for de-escalated radiation has been an area of active investigation, active research. And it also remains a key opportunity to evaluate predictive biomarkers and understanding pre and post treatment to better understand the biology. I'll just add to your question that recently over this past year, we also saw for neoadjuvant immunotherapy for a subset of head and neck cancer that is surgically resectable. And so that's reintroducing the potential benefit in the immunotherapy era of incorporating immunotherapy in the neoadjuvant or the induction setting as part of the evolving treatment paradigm for these diseases. Dr. Monty Pal: That's really interesting. And you kind of alluded to already several topics that I plan to hit on, you know, for instance, the role of immune checkpoint inhibitors, induction, chemotherapy, and so forth. And you started to touch on biomarkers. And of course, I think that's something near and dear to many of us in academic oncology. One thing that we've started talking a lot about in the context of colorectal cancer is circulating tumor DNA. How do you think this might fit in the context of head and neck cancer? Can you give us a flavor for that? Dr. Ari Rosenberg: Yeah, absolutely. In head and neck cancer, the current landscape is most developed for circulating tumor DNA for HPV-related head and neck cancer. The advantage of HPV-related head neck cancer is that you have a distinctive HPV DNA that does tend to spill out into the peripheral blood and can be detected using various different blood-based assays. And because of that advantage as a tissue agnostic approach, it turns out that a number of HPV DNA plasma assays are actually quite sensitive and quite specific. And a number of them have indeed been commercialized. Of course, not only for detecting a baseline, but also grading responsiveness during treatment and probably most importantly in the post-treatment surveillance setting, the detection of HPV DNA in the plasma remains a very important and substantial predictor of developing recurrent disease. There's been a number of trials that have been emerging looking at ctDNA and HPV-related head and neck cancer, using it, for example, as a strategy to deescalate patients. That was something we saw this past ASCO from the Dana-Farber group, and also using it to early detect recurrence and potentially intervene earlier for patients with minimal residual disease positivity. So, that remains evolving and as many folks are, I think, already using it in the clinic. But ctDNA also has a lot of potential for HPV-negative head and neck cancer. This is actually a bit more challenging to develop because you don't have that HPV DNA that you can track predictably because the tumor is an HPV- negative disease are much more heterogeneous, but there are a number of data that are coming out both for personalized assays such as Signatera or some of the other assays that require tumor. Unlike colon cancer, which you referenced, where most patients get surgery upfront, in head and neck cancer, many of the patients receive non-surgical pre-chemoradiation. So sometimes the amount of tumor available to generate a personalized assay is more limited and can be one of the challenges that we see in head neck cancer. But certainly that also seems to be emerging. And there's also further assays that are being developed for HPV-negative head neck cancers, such as methylomic signatures and others that may be tissue informed or tissue agnostic. And these are also emerging, particularly in the post-treatment surveillance setting as strong predictors of recurrent disease. So while we're certainly behind some of these other more common tumor types, colon cancer, lung cancer, we're right there with them and more and more trials are going report out, including a number of trials in our upcoming [University of Chicago] Head and Neck Cancer Symposium where I'll be presenting some data and others in the field will be presenting some data looking at ctDNA both for HPV-positive and for HPV- negative to try to improve outcomes for these patients. Dr. Monty Pal: That's so interesting. I've got to tell you that in kidney cancer, what I deal with day to day is a very low shedding disease, right? So techniques as opposed to ctDNA looking for tumor-informed information, that might be less preferred to something like methylomics where you might not necessarily be so contingent on what's happening in the primary tumor. I'm really interested in you mentioning that. Just a point of clarification, this is something I'm trying to wrap my head around. You'd mentioned circulating tumor HPV DNA, right? I assume this is markedly different from just looking for HPV titers in the patient, right? So is this actually incorporated elements of HPV within, you know, essentially host genome, if you will? Dr. Ari Rosenberg: Yeah, correct. This is circulating tumor HPV DNA. And we think of it biologically as a plasma-based tumor DNA biomarker that's specific for HPV-related head and neck cancers. Dr. Monty Pal: Got it, got it. It makes me wonder whether or not this might be applicable to diseases like cervical cancer and so forth where there's also extensively, you know, biology driven by HPV. Is that fair? Dr. Ari Rosenberg: Yes, definitely. And in the head and neck cancer field, much of this ctDNA actually was derived from a different viral mediated head neck cancer, is less common in the U.S., but nasopharyngeal cancer, which is oftentimes associated with EBV. That has been a biomarker for quite some time in nasopharyngeal cancer. Of course, in places where EBV-associated nasopharyngeal cancer, is endemic, such as East Asia, this has been around for quite some time, but we've been using that in the U.S., and there's been trials that have used EBV DNA plasma to predict recurrence and stratify for adjuvant treatment, for example. And so now with HPV, it's much more applicable to our US population because the vast majority of our head and neck cancer patients that we see in the US that are viral mediated in the US tend to be HPV-related. So having assays that we can use to improve outcomes for that biological subset remains of particular interest for us. Dr. Monty Pal: Yeah, that's fascinating. By the way, for the fellows listening, there's tons of boards pearls here that Dr. Rosenberg shared, EBV-associated cancers, the role of HPV and treatment association. So if you're recertifying anytime soon, I definitely think there's notes to take from this conversation indeed. I wanted to shift gears a little bit. And obviously, you're a prolific researcher. I don't think anyone goes through their fellowship in medical oncology without recounting these experiences of our head and neck patients really suffering from treatment-related toxicities. It's a real challenge. And I'm just wondering, I know a big body of work that you're focused on is really using multimodality treatment paradigms to perhaps reduce the cumulative treatment burden of patients with head and neck cancers. Can you talk about that a little bit? Dr. Ari Rosenberg: Yeah, definitely. Thanks for the question. And before I start going into some of the strategies, I'll just say that head and neck cancer, this is particularly for the fellows that are listening as well, just in reference to your prior comment, that this is really a multidisciplinary disease. At our center, all head and neck cancer patients are seen upfront at that first visit by all three specialties, med onc, rad onc, and surgery, because the choice and sequencing of modalities to optimize not only survival, but also functional quality of life outcome is so critical. And I think that's probably the biggest takeaway for anyone who treats a lot of head and neck cancer or will be treating a lot of head and neck cancer in the clinic. But in terms of more specific attempts at trying to optimize some of those parameters that you described, we really think about these separately in terms of HPV-positive and HPV-negative head and neck cancer. For HPV-positive head and neck cancer, the cure rates are quite high with chemo radiation, although not for everyone. There's still about 15, 10 to 15 % of folks that will develop a recurrence. But for the vast majority of patients, standard chemoradiation is quite a cure to therapy, but the toxicity associated with that can be quite substantial. And so there's been a number of attempts to try to deescalate treatment. It turns out that deescalating everyone with locoregionally advanced HPV-positive head and neck cancer is not a good strategy because it's not able to select out the patients that really do need full dose treatment. And we have seen some negative trials that show inferior outcomes when everyone is deescalated. But what does remain promising is again, trying to select out who the best candidates are for deescalated treatment. The folks at MSK have hypoxia imaging that they're using in trials that looks quite promising to select for the more favorable deescalatable biology. At our center, we've been interested in using induction chemotherapy to stratify response and select patients for deescalated treatment with excellent survival outcomes and reduce toxicity with deescalated treatment. And more recently, ctDNA that us and other groups, such as the Dana-Farber group, is using. And that also looks quite promising. Again, how do you select the patient who will do well with less radiation versus the ones that really need the full doses and volumes of radiation? And then for HPV-negative head and neck cancer, this is a much trickier disease because already the survival outcomes are not like we want it to be. Trying to figure out how to improve survival outcomes remains an important thing. Using immunotherapy seems to be one of the key cornerstones to that. But these are patients that also suffer from a lot of toxicity related to their treatment. We completed a not too long ago that we published this past year where we, in HPV-negative head and neck cancer patients, de-intensified the radiation for responders to neoadjuvant chemoimmunotherapy. And those patients did similar, if not even a little bit better, than the non-responders who got full dose treatment. So something that does warrant further investigation as well. How do we not only improve survival for those patients, but also reduce some of the long-term toxicities? Dr. Monty Pal: This is brilliant. I'm taking so many notes as you were mentioning these items. There are so many areas where I think the research crosses over. I already mentioned, know, ctDNA, for instance, and metabolomics and the places where that might apply to kidney cancer. The hypoxia imaging really caught my ear too. Obviously, kidney cancer is disease highly predicated on hypoxia. So thank you for all of this. We've got about a minute or so. So, I'm going to ask you for a really tall task here. Can you tell us what you foresee being some of the biggest challenges that sort of lie ahead and head and neck cancer. You've already kind of alluded to it with ongoing research, but if you had to pick maybe 2, 3 problems, the very most that we really need to get to and head and neck cancer, what would that be? Dr. Ari Rosenberg: Yeah, that's a great question. Obviously, lots of things to be done, but if I'm going to limit it to just a couple, I would say number one is really trying to improve the survival for HPV negative local regionally advanced head and neck cancer. We talked early on about how we are seeing, you know, of course we see many of these people that were smokers and drinkers, but also seeing these in younger patients, in patients without a history of tobacco use. Some of these are very biologically aggressive and we need better treatments beyond surgery, beyond chemo radiation, beyond immunotherapy to improve outcomes for these patients and cure more of them. So, I would say that's one big area. And the other is, which we didn't speak about so much in this talk, but remains one of the biggest challenges that we see in the clinic is the recurrent metastatic head and neck cancer patients. This is an incredibly challenging disease to treat, not only with poor survival, but also with substantial impacts on quality of life and function. mean, these are bad recurrences that... /episode/index/show/ascodaily/id/40154430

Can Low-Dose Immunotherapy Expand Global Access to Cancer Care? 02/05/2026

Can Low-Dose Immunotherapy Expand Global Access to Cancer Care? Dr. Monty Pal and Dr. Atul Batra discuss the PLANeT study from India, which evaluated low-dose pembrolizumab in addition to neoadjuvant chemotherapy for triple-negative breast cancer, and its place among a growing body of international research on improving efficacy while reducing costs and toxicity with lower doses of immunotherapy. TRANSCRIPT Dr. Monty Pal: Hello and welcome to the ASCO Daily News Podcast. I'm your host, Dr. Monty Pal. I'm a medical oncologist, professor, and vice chair of academic affairs at the City of Hope Comprehensive Cancer Center, Los Angeles. My guest today, I think, is going to be a really riveting one. It's Dr. Atul Batra, who is an additional professor of medical oncology at the All India Institute of Medical Sciences, or AIIMS, in New Delhi. And he's also the senior author of the study. It's a very compelling study that evaluated low-dose pembrolizumab in addition to neoadjuvant chemotherapy for triple-negative breast cancer. And it's really a big part of a growing body of research that's showing balanced efficacy when we use lower doses of immunotherapy instead of standard doses to reduce cost, as well as potentially toxicity. I think this has huge implications for our global audience, and I'm so thrilled to have you on the podcast today, Dr. Atul Batra, welcome. Dr. Atul Batra: Thank you, Dr. Pal. Dr. Monty Pal: And we'll just take it with first names from here since we're both friends. I have to give the audience some context. Atul, I had the great honor of visiting AIIMS New Delhi. For those that don't know, this is really, you know, the Harvard Medical School of India. It's the most competitive institution for medical training. And on the back end of that, there's also incredible resources when it comes to clinical trials and infrastructure. I just wanted to have you give the audience sort of a scope of the types of trials that you've been able to do at AIIMS New Delhi. Dr. Atul Batra: Thank you, Monty. So, I work at the All India Institute of Medical Sciences, and we had the honor and pleasure of having Monty here this month. And people are still in awe of his lectures that he delivered there. Coming back to our institute, so it's kind of a medical college. It's one of the oldest ones, it was built in 1956. We are lucky enough that we get the best of the residents and fellows because they have to go through an exam, a competitive exam, and mostly it's them who come to us and we're able to do some good work out here. Regarding the trials that we have conducted, we do conduct some investigator-initiated studies, and we try to answer the questions where we can help our own patients. Like, for example, this PLANeT study. Every other patient in the clinic was almost not able to afford Keytruda at the full dose, pembrolizumab, and we had a lot of evidence creeping in that a lower dose might be helpful. And that's how we planned this study. Before that, there are certain cancers that are peculiar to India, like gallbladder cancer, head and neck cancers. These are much more common in India as compared to the U.S., and there are some good studies that have been conducted from our own institute by our senior colleagues which have been presented at ASCO and published in the JCO. We also did the capecitabine hand-foot syndrome study that was known as the study: 1% diclofenac gel that became the standard of care to prevent hand-foot syndrome. So, that's kind of a brief overview of investigator-initiated studies. India is slowly and steadily becoming a partner of the global registration trials. And it's more recently, the last five years or so, we have seen that the number of phase 2 and phase 3 trials are increasing and we are able to offer now these trials as well to our patients. Dr. Monty Pal: That was a terrific overview. I just want to highlight for the audience, as we go through some of your discussions today around specific trials, the speed at which this can be done. Just for context, for me to accrue a clinical trial of 30 patients – I think many people have probably come across some of the work that I've done in the microbiome space – at a single institution, 30 patients, right, takes me about a year and a half, two years. We're going to go through some trials today where Dr. Batra and his team have actually, in fact, accrued close to 200 patients over a span of just a year, which is just remarkable by, I would say, any American standard. So, I see a real need for partnership and Atul, I'll kind of get back to that at the end. But without further ado, the focus of this podcast today, I think, is really this terrific presentation you gave in an oral session at ESMO and subsequently published in Annals of Oncology related to the PLANeT study. Would you give the listeners some context around what the study entailed and population and so forth? Dr. Atul Batra: So, we know the became the standard of care for triple-negative breast cancer, where Keytruda, when added at 200 mg, the standard dose every three weeks with neoadjuvant, increases the pCR from around 51% to 64% by a magnitude of around 13%. However, in India and other low-middle income countries, less than 5% of the patients actually have access to this dose of pembrolizumab. So, our standard of care was actually just chemotherapy till now. And this kind of led us to design this trial. There are data that come from previous trials conducted in India, from the Tata Memorial, done in head and neck space, some other studies done in Hodgkin's lymphoma, that a much lower dose, probably around one-tenth of the dose, works well in these cancers. So, that's where we designed the PLANeT study, where we gave the standard neoadjuvant chemotherapy in the control arm, and in the experimental arm we added 50 mg of pembrolizumab. This was given every six weeks for three doses. So, that's a total of 150 mg over the neoadjuvant period as compared to 1,600 mg that was given in the KEYNOTE-522 study. So, this was almost one-tenth of the study. Dr. Monty Pal: So, a tenth of the dose, which is just remarkable. I mean, that's just such an interesting concept. Dr. Atul Batra: And the results, when we – the primary outcome, this was a phase 2 study. We just wanted to see, is there a signal of activity? And to even our surprise, when we looked at the pathological complete response rates, in the control arm this was 40.5%, and in the experimental arm this was 53.8%. So, a difference came to around 13.3%; it was numerically, I mean, so much similar to what KEYNOTE-522 had with just these many doses. So, this was around 160 patients randomized over one year. We could randomize them in one year because of the load that we see. And the primary endpoint was met, and we could see that the path complete response did show a remarkable increase. We are still following these patients to see whether there is a difference in event-free survival at a longer follow-up. Until now, it's a small follow-up, so the number of events absolute, are different: four events in the experimental arm and 11 events in the control arm. So, we are seeing some signal even in this much short follow-up period as well. But we need to see more of what happens in the longer term. Dr. Monty Pal: That's so impressive. I wonder, with this lower dose, do you attenuate toxicity at all as far as you can gather? Dr. Atul Batra: So, although we shouldn't be doing kind of cross-trial comparisons, but if you look at thyroid dysfunction, we saw that around 10% of our patients had this thyroid dysfunction. This was compared to 15% in the KEYNOTE-522, that was a larger sample size though. But we're seeing that all the toxicities are somewhat less as compared to those in the standard dose. So, the exposure is less, but I mean, I can't really commit definitely on this. For this we would need much more data to say this with more confidence. Dr. Monty Pal: Yeah. I'm going to ask you a really tough question to follow up, and this is probably something that's on everyone's mind after reading a study like this. Is this something that is disease-specific that needs to be replicated across other histologies? The reason I ask this is, you know, you think about paradigms like, for instance, in the States we're toying between intravenous versus subcutaneous delivery of checkpoint inhibitors, and we have studies focused in specific histologies that might justify use across all histologies. With this particular phenomenon, do you think we need to do dedicated studies in renal cell or in colon cancer and other places where, you know, in selected settings we might use checkpoint inhibitors and then decide whether or not there's this dose equivalence, if you will? Dr. Atul Batra: That's a real tough one, though. But I'm happy to share that there are several ongoing studies within India currently. At our institute, my colleagues are leading studies in lung cancer space, cervical cancer. There was already a from Tata Memorial Hospital in head and neck cancers and we see that the signal has been consistent throughout. Regarding renal cancer, there was one study that was presented for sure at ASCO from CMC Vellore, that's again a center in South India. That was in RCC at a much lower dose. And for patients who cannot take the full dose, we actually are offering lower dose nivolumab in such patients and we are seeing responses. I mean, we haven't done those randomized trials again because the numbers are much lower in kidney cancers, we know. We could do this trial in triple-negative ones because we had support and we had numbers to conduct this trial. But I'm sure this should be a class effect. I mean, when we can get tumor-agnostic approvals, then some real-world data has come up in almost all tumors, we have seen that consistent effect across tumors. And as we speak of today, I'm also delighted to share that in India, yesterday, we had the first biosimilar of nivolumab and that's now available at a much, much lower price than the original patent product. There was a long ongoing lawsuit that was there, that's over now, and from yesterday onwards, I'm so happy to share here that we would have the first biosimilar of nivolumab that's available. That's going to bring the cost to almost like one-tenth already. Dr. Monty Pal: Wow. That's huge. I'm going to be very selfish here for a second and focus on a that is in the renal cell space that your group has done. You know, when it came out, I was really sort of intrigued by this study as well and it reflects sort of a different capability, I think, of AIIMS New Delhi, and that's in the, what I'm going to call, biomarker space. This, for the audience, was a prospective effort to characterize germline variants in patients with advanced kidney cancer. And it's something that we talk about a lot in the kidney cancer literature, whether or not we're missing a lot of these so-called hereditary patterns of RCC. Can you tell us a little bit about that study too? Dr. Atul Batra: Yeah, so that was led by one of our fellows, Chitrakshi Nagpal, and she's just completed her fellowship. And two years back we published that. So, that was done in almost 160 consecutive patients that we recruited over the span of just one year and we saw, apart from the common known mutations in RCC, that was around 5% or so, but a lot of other mutations were also seen that we don't generally see in kidney cancers and we see in other cancers like BRCA1, BRCA2 and others. We are still, I mean, doing those analyses to see whether we get more things out of there in the somatic: is there a loss of heterozygosity or was it just present and in there? Dr. Monty Pal: I thought it was a terrific study and again, I was just so blown away at the pace. I mean, as I look at 140 patients accrued over a span of one year, this is something that would take us perhaps three times as long at City of Hope, and that's with a very sort of, what I consider to be large and dedicated kidney cancer program. So, it really underscores, I think, the need for collaboration. And ever since I came back from my visit to you at AIIMS Delhi, I think I've just been sort of transformed in the sense of trying to think of better ways for us to collaborate. One tangible thing that I'm going to get cracking on is seeing whether or not perhaps we can form some partnerships through SWOG or what we call the NCTN, the National Clinical Trials Network here within the U.S. Talk to me about collaboration. I mean, you've been really terrific at this. How do you sort of envision collaboration enhancing the global landscape of oncology? Dr. Atul Batra: That's really amazing, Monty. That's what we need. We have the infrastructure, we have the manpower, we have patients. I mean, these are all high-volume centers. Unfortunately, we are a little less in numbers, so we are more clinically occupied as well. So, sometimes it's kind of tougher, but again, when it comes to helping out the patients, global collaboration, we need to kind of take you guys along with us and have our patients finish trials earlier. This is a win-win situation for patients, one, because they also get exposure or an option to participate in the clinical trials, and second, we can answer all these scientific questions that we have at a much faster pace. All those things can be done within a much shorter span of time for sure. We are so happy to hear that, and with open hands we are ready to collaborate for all these efforts. Dr. Monty Pal: That's awesome. You know, I came back thinking, gosh, this would be so ideal for some of these rare subtypes of kidney cancer. Prospective clinical trials that I'm running in that space where really we're threatened with closure all the time. And if we just sort of extended a hand to, you know, our partners in India and other countries, you know, I'm sure we could get this research done in a meaningful way and that's got to be a win for patients. Atul, I had such a terrific time chatting with you today. I'm looking forward to seeing lots more productivity from your group there. By the way, for our viewership here, take a look and see what AIIMS New Delhi is doing under the leadership of Dr. Batra and others. It is just a real powerhouse and I think that after doing so, you'll be enticed to collaborate as well. I'm hoping this is the first of many times that we have you on the podcast. Thank you so much for joining. Dr. Atul Batra: Thank you so much for having me here, Monty. It was a pleasure as always speaking to you. And thank you again. Dr. Monty Pal: You got it. Well, and thanks to our listeners. I encourage you to check out Dr. Batra's paper. We'll actually have a link to the study in the transcript of this episode.

Expanding Treatment Options for Breast Cancer: ADCs and Oral SERDs 01/08/2026

Expanding Treatment Options for Breast Cancer: ADCs and Oral SERDs Dr. Monty Pal and Dr. Hope Rugo discuss advances in antibody-drug conjugates for various breast cancer types as well as treatment strategies in the new era of oral SERDs for HR-positive breast cancer. TRANSCRIPT Dr. Monty Pal: Hello, and welcome to the ASCO Daily News Podcast. I’m your host, Dr. Monty Pal. I’m a medical oncologist and vice chair of academic affairs here at the City of Hope Comprehensive Cancer Center, Los Angeles. Today, I’m thrilled to be joined by Dr. Hope Rugo, an internationally renowned breast medical oncologist and my colleague here at City of Hope, where she leads the Women’s Cancers Program and serves as division chief of breast medical oncology. Dr. Rugo is going to share with us exciting advances in antibody-drug conjugates (ADCs) that are expanding treatment options in various breast cancer types. She’ll also address some of the complex questions arising in the new era of oral SERDs (selective estrogen receptor degraders) that are revolutionizing treatment in the hormone receptor-positive breast cancer space. Our full disclosures are available in the transcript of this episode. Dr. Rugo, welcome, and thanks so much for being on the podcast today. Dr. Hope Rugo: Thank you. Pleasure to be here. Dr. Monty Pal: So, I’m going to switch to first names if you don’t mind. The first topic is actually a really exciting one, Hope, and this is antibody-drug conjugates. I don’t know if I’ve ever shared this with you, but I actually started my training at UCLA, I was a med student and resident there, and it was in Dennis Slamon’s lab. I worked very closely with Mark Pegram and a handful of others. This is right around the time I think a lot of HER2-directed therapies were really evolving initially in the clinics. Now we’ve got antibody-drug conjugates. Our audience is well-familiar with the mechanism there but tell us about how ADCs have really started to reshape therapy for HER2-positive breast cancer. Dr. Hope Rugo: Yeah, I mean, this is a really great place to start. I mean, we have had such major advances in breast cancer just this year, I think really changing the paradigm of treating patients. But HER2-positive disease, we’ve been used to having sequenced success of new agents. And I think the two biggest areas where we’ve made advances in HER2-positive disease, which were remarkably advanced this year in 2025, have been in antibody-drug conjugates with trastuzumab deruxtecan and with new oral tyrosine kinase inhibitors (TKIs) that have less of a target on EGFR and more on HER2, so they have an overall more tolerable toxicity profile and therefore a potentially better efficacy in the clinic. At least that’s what we’re seeing with these new strategies that we couldn’t really pursue in the past because of toxicities of the oral TKIs. So, although our topic is ADCs, I’m going to include the TKI because it’s so important in our thinking about treating HER2-positive disease. In the metastatic setting, we’ve seen these remarkable improvements in progression-free and overall survival in the second-line setting with T-DXd, or trastuzumab deruxtecan, compared to T-DM1. And then sequencing ADCs with giving T-DXd after T-DM1 was better than an oral tyrosine kinase or a trastuzumab combination with standard chemotherapy. That was and . So, then we’ve had other trials since then, and T-DXd has moved into the early-stage setting, which I’ll talk about in just a moment. But the next big trial for T-DXd in HER2-positive disease was moving it to the first-line setting to supplant what has become an established treatment for now quite a long time: the so-called regimen, which used the combined antibodies trastuzumab, pertuzumab with a taxane as first-line therapy. And then we’ve proceeded on with maintenance with ongoing HP for patients with responding or stable disease. And we’d seen long-term data showing, you know, at 8 years there was a group of patients whose cancers had never progressed and continued improved overall survival. So, T-DXd was studied in , either alone or in combination with pertuzumab compared to THP. The patient population had received a little bit more prior treatment, but interestingly, not a lot compared to CLEOPATRA. And they designed the trial to be T-DXd continued until progression with or without pertuzumab versus THP, which would go for six cycles and then stop around six cycles, and then stop and continue HP. Patients who had hormone receptor-positive disease could use hormone therapy, and this is one of the issues with this dataset because, surprisingly in this dataset and one other I’ll mention, very few patients took hormone therapy. And even in the maintenance trial, the , less than 50% took hormone therapy as maintenance. This is kind of shocking to me and highlights an area of really important education, that outcome is improved when you add endocrine therapy for hormone receptor-positive HER2-positive metastatic disease in the maintenance phase, and it’s a really important part of treatment. But suffice it to say, you know, you’re kind of studying continued chemo versus stopping chemo in maintenance. And T-DXd, as we all expected, in combination with pertuzumab was superior to THP in terms of progression-free survival, really remarkably improved. And you could stop the chemo with toxicity, but most people continued it with T-DXd. Again, not a lot of people got hormone therapy, which is an issue, and you stop the chemo in the control arm. So, this has brought up a lot of interest in trying to use T-DXd as an induction and then go to maintenance, much as we do with the CLEOPATRA regimen with hormone therapy. But it brings up another issue. So first, T-DXd is superior; it’s a great treatment. Not everybody needs to have it because we don’t know whether it’s better to give T-DXd first or second with progression - that we need a little bit longer follow-up. But just earlier this week, interestingly, the third week of December, the U.S. FDA approved T-DXd in the DESTINY-Breast09 approach with pertuzumab. So as I mentioned earlier, there was a T-DXd-alone arm; that arm has not yet reported. So very interesting, we don’t know if you need pertuzumab or not. So what about the maintenance? That’s the other area where we’ve made a huge advance here. So, we all want to stop chemo and we want to stop T-DXd. You don’t want somebody being nauseated for two years while they’re on treatment, and also there’s a small number of patients with mostly de novo metastatic HER2-positive disease who are cured of their disease. We’d like to expand that, and I think these new drugs give us the opportunity to improve the number of patients who might be cured from metastatic disease. So the first maintenance study we saw was adding palbociclib, the CDK4/6 inhibitor, to endocrine therapy and HP, essentially. There, we had a remarkable improvement in progression-free survival difference of 15.2 months: 29 to 44 months, really huge. At San Antonio this year, we saw data with this oral tyrosine kinase inhibitor tucatinib, already showed it was great in a triplet, but as maintenance in combination with HP, it showed also a remarkable improvement in progression-free survival. But the numbers were all shifted down. So in , the control arm was in the 24-month range; here it was the tucatinib-HP arm that was in the 25 months and 16 months for control. So there was a differential benefit in ER-negative and ER-positive disease. So I think we’re all thinking that our ideal approach moving forward would be to give T-DXd to most patients, we see how they do, and treat to best response. And then, stop the T-DXd, start HP, trastuzumab, pertuzumab for ER-negative, with tucatinib for ER-positive with palbociclib. We also have early data that suggests that both approaches may reduce the development of brain metastases, an issue in HER2-positive disease, and delay time to progression of brain metastases as seen in HER2CLIMB-05 in very early data - small numbers, but still quite intriguing that you might delay progression of brain metastases with tucatinib that clearly has efficacy in the brain. So, I think that this is a hugely exciting advance for our patients, and these approaches are quickly moving into the early stage setting. T-DXd compared to standard chemo, essentially followed by THP, so a sequenced approach resulted in more pathologic complete responses than a standard THP-AC-type neoadjuvant therapy. T-DXd alone for eight cycles wasn’t better, and that’s interesting. We still need the sequenced non-cross-resistant chemo. But I think even more importantly, the data from looking at T-DXd versus T-DM1 in patients with residual disease after neoadjuvant HER2-targeted therapy showed a remarkable improvement in invasive disease-free survival with T-DXd versus T-DM1, and quite early. It was a high-risk population, higher risk than the T-DM1 trial with , but earlier readout with a remarkable improvement in outcome. We expect to be FDA approved sometime in the first half of 2026. So then we’ll get patients who’ve already had T-DXd who get metastatic disease. But my hope is that with T-DXd, maybe with tucatinib in the right group of patients or even sequenced in very high-risk disease, that we could cure many more patients with early-stage HER2-positive breast cancer and cure a subset, a greater subset of patients with de novo metastatic disease. Dr. Monty Pal: That’s brilliant. And you tackled so many questions that I was going to follow up with there: brain metastases, etc. That was sort of looming in my mind. I mean, general thoughts on an ADC versus a TKI in the context of brain mets? Dr. Hope Rugo: Yeah, it’s an interesting question because T-DXd has shown quite good efficacy in this setting. And tucatinib, of course, had a trial where they took patients with new brain mets, so a larger population than we’ve seen yet for the T-DXd trials, and saw that not only did they delay progression of brain metastases and result in shrinkage of existing untreated brain mets, but that patients who develop a new brain met, they could stay on the same assigned treatment. They got stereotactic radiation, and then the patients who were on tucatinib with trastuzumab and capecitabine had a further delay in progression of brain mets compared to those on the placebo arm, even after treatment of a new one that developed on treatment. So, I think it’s hard. I think most of us for a lot of brain mets might start with the tucatinib approach, but T-DXd is also a very important treatment. You know, you’re kind of trading off a diarrhea, some liver enzyme elevations with tucatinib versus nausea, which you really have to work on managing because it can be long-delayed nausea, and this risk of ILD, interstitial lung disease, that’s about 12%, with most but not all trials showing a mortality rate from interstitial lung disease of just under 1 percent. In the early-stage setting, it was really interesting to see that with T-DXd getting four cycles in the neoadjuvant setting, a lot less ILD noted than the patients who got up to 14 cycles, as I think they got a median of 10 cycles in the post-surgical setting, there was a little bit more ILD. But I think we’re going to be better and better at finding this earlier and preventing mortality by just stopping drug and treating earlier with steroids. Dr. Monty Pal: And this ILD issue, it always seems to resurface. There are drugs that I use in my kidney cancer clinic, everolimus, common to perhaps the breast cancer clinic as well, pembrolizumab, where I think the pattern of pneumonitis is quite different, right? What is your strategy for recognizing pneumonitis early in this context? Dr. Hope Rugo: Well, it is, and you know, having done the very early studies in everolimus where we gave it in the neoadjuvant setting and we’re like, "Hmm, the patient came in with a cough. What’s going on?" You know, we didn’t know. And you have mouth sores, you know, we were learning about the drug as we were giving it. What we don’t do with everolimus and CDK4/6 inhibitors, for example, is grade 1 changes like radiation pneumonitis, we don’t stop, we don’t treat it. We only treat for symptoms. But because of the mortality associated with T-DXd, albeit small, we stop drug for grade 1 imaging-only asymptomatic pneumonitis, and some of us treat with a half dose of steroids just to try and hasten recovery. We’ve actually now published or presented a couple of datasets from trials, a pooled analysis and a real-world analysis, that have looked at patients who were retreated after grade 1 pneumonitis or ILD and tolerated drug very well and none of them died of interstitial lung disease, which was really great to see because you can retreat safely and some of these patients stayed on for almost a year benefiting from treatment. So, there’s a differential toxicity profile with these drugs and there are risk factors which clearly have identified those at higher risk: prior ILD, for example. A French group said smoking; other people haven’t found that, maybe because they smoked more in France, I don’t know. And being of Japanese descent is quite interesting. The studies just captured that you were treated in Japan, but I think it’s probably being of Japanese descent with many drugs that increases your risk of ILD. And, you know, older patients, people who have hypoxia, those are the patients. So, how do we do this? With everolimus, we don’t have specific monitoring. But for T-DXd we do; we do every nine weeks to start with and then every 12 weeks CT scans because most of the events occur relatively early. Somebody who’s older and at higher risk now get the first CT at six weeks. Dr. Monty Pal: This is super helpful. And I have to tell you, a lot of these drugs are permeating the bladder cancer space which, you know, is ultimately going to be a component of my practice, so thank you for all this. We could probably stay on this topic of HER2-positive disease forever. I’m super interested in that space still. But let me shift gears a little bit and talk about triple-negative breast cancer and this evolving space of HR-positive, HER2-low breast cancer. I mean, tell us about ADCs in that very sort of other broad area. Dr. Hope Rugo: So triple-negative disease is the absolute hardest subset of disease that we have to treat because if you don’t have a great response in the early stage setting, the median survival is very short, you know, under two years for the majority of TNBCs, with the exception of the small percentage of low proliferative disease subsets. The co-question is what do we do for these patients and how do we improve outcome? And sacituzumab govitecan has been one strategy in the later line setting that was shown to improve progression-free and overall survival, the . We had recently three trials presented with the two ADCs, sacituzumab govitecan and the other Trop-2 ADC that’s approved for HR-positive disease, datopotamab deruxtecan. And they were studied in the first-line setting. Two trials with SG, sacituzumab govitecan, those trials, one was PD-L1 positive, . That showed that SG with a checkpoint inhibitor was superior, so pembrolizumab was superior to the standard type of treatment with either a taxane or gemcitabine and carboplatin with pembrolizumab for patients who have a combined positive score for PD-L1, 10 or greater. So, these are patients who are eligible for a checkpoint inhibitor, and SG resulted in an improved progression-free survival. The interesting thing about that dataset is that few patients had received adjuvant or neoadjuvant checkpoint inhibitor, which is fascinating because we give it to everybody now. But access is an issue and timing of the study enrollment was an issue. The other thing which I think we’ve all really applauded Gilead for is that there was automatic crossover. So, you could get from the company, to try and overcome some of the enormous disparities worldwide in access to these life-saving drugs, you could get SG through the company for free once you had blinded independent central review confirmation of disease progression. Now, a lot of the people who got the SG got it through their insurance, they didn’t bill the company, but 80 percent of patients in the control arm received SG in the second-line setting. So that impacts your ability to look at overall survival, but it’s an incredibly important component of these trials. So then at ESMO, we saw the data from SG and Dato-DXd in the first-line metastatic setting for patients who either had PD-L1-negative disease or weren’t eligible for an immunotherapy. For the Dato study, , that was 10 percent of the patients who had PD-L1-positive disease but didn’t get a checkpoint inhibitor, and for the trial population it was only 1 percent. Importantly, the trials allowed patients who relapsed within a year of receiving their treatment with curative intent, and the Dato study, TB-02, allowed patients who relapsed while on treatment or within the first six months, and that was 15 percent of the 20 percent of early relapsers. The ASCENT trial, ASCENT-03, had 20 percent who relapsed between 6 and 12 months. The drugs were better than standard of care chemotherapy, the ADCs in both trials, which is very nice. Different toxicity profiles, different dosing intervals, but better than standard of care chemotherapy in the disease that’s hardest for us to treat. And importantly, when you looked at the subset of early relapsers, those patients also did better with the ADC versus chemotherapy, which is incredibly important. And we were really interested in that 15 percent of patients who had early relapse. I actually think that six months thing was totally contrived, invented, you know, categorization and doesn’t make any sense, and we should drop it. But the early relapsers were 15 percent of TB-02 and Dato was superior to standard of care chemo. We like survival, but the ASCENT trial again allowed the crossover to an approved ADC that improved survival and 80 percent of patients crossed over. In the Dato trial, they did not allow crossover, they didn’t provide Dato, which isn’t approved for TNBC but is for HR-positive disease, and they didn’t allow, of course, pay for SG. So very few patients actually crossed over in their post-treatment data and in that study, they were able to show a survival benefit. So actually, I think in the U.S. where we can use approved drugs already before there’s a fixed FDA approval, that people are already switching to use SG or Dato in the first-line setting for metastatic TNBC that’s both PD-L1 positive for SG and PD-L1 negative for both drugs. And I think understanding the toxicity profiles of the two drugs is really important as well as the dosing interval to try and figure out which drug to use. Dr. Monty Pal: Brilliant. Brilliant. Well, I’m going to shift gears a little bit. ADCs are a topic, again, just like HER2-positive disease we could stay on forever. Dr. Hope Rugo: Huge. Yes. Dr. Monty Pal: But we’re going to shift gears to another massive topic, which is oral SERDs. In broad strokes, right, this utilization of CDK4/6 inhibitors in the context of HR-positive breast cancer is obviously, you know, a paradigm that’s been well established at this point. Where do we sequence in oral SERDs? Where do they fit into this paradigm? Dr. Hope Rugo: Ha! This is a rapidly changing area; we keep changing what we’re saying every other minute. And I think that there are three areas of great interest. So one is patients who develop ESR1 mutations that allow constitutive signaling through the estrogen receptor, even when there’s not estrogen around, and that is a really important mutation that is subclonal; it develops under... /episode/index/show/ascodaily/id/39632905

What Challenges Will Oncologists Face in 2026? 12/04/2025

What Challenges Will Oncologists Face in 2026? Dr. Monty Pal and Dr. Jason Westin discuss the federal funding climate for cancer research and the persistent problem of drug shortages, two of the major concerns facing the oncology community in 2026. TRANSCRIPT Dr. Monty Pal: Hello and welcome to the ASCO Daily News Podcast. I am your host, Dr. Monty Pal. I am a medical oncologist and vice chair of academic affairs at the City of Hope Comprehensive Cancer Center in Los Angeles. There are always multiple challenges facing oncologists, and today, we discuss two of them that really stand out for 2026: threats to federal funding for cancer research and the persistent problem of drug shortages. I am thrilled to welcome Dr. Jason Westin, who believes that one way to meet these challenges is to get oncologists more involved in advocacy, and he will share some strategies to help us meet this moment in oncology. Dr. Westin is a professor in the Department of Lymphoma and Myeloma at the University of Texas MD Anderson Cancer Center, but he actually wears a lot of hats within ASCO. He is a member of the Board of Directors and has also previously served as chair of ASCO's Government Relations Committee. And he is also one of the inaugural members of ASCO's Political Action Committee, or PAC. He has testified before Congress about drug shortages and many other issues. Dr. Westin, I am really excited to have you on the podcast today and dive into some of these elements that will really impact our community in 2026. Thanks so much for joining us today. Dr. Jason Westin: Thank you for having me. Dr. Monty Pal: You've had such a range of experience. I already alluded to you testifying before Congress. You've actually run for office before. You wear so many different hats. I'm used to checking my PubMed every other day and seeing a new paper out from you and your group, and you publish in the New England Journal [of Medicine] on practice-setting standards and the diseases that you treat. But you've also done all this work in the domain of advocacy. I can't imagine that balancing that is easy. What has sort of motivated you on the advocacy front? Dr. Jason Westin: Advocacy to me is another way to apply our skills and help more people than just those that you're sitting across from at the time. Clinical research, of course, is a tool to try and take what we know and apply it more broadly to people that you'll never meet. And advocacy, I think, can do the same thing, where you can have a conversation with a lawmaker, you can advocate for a position, and that hopefully will help thousands or maybe even more people down the road who you'd never get to directly interact with. And so, I think it's a force multiplier in the same way that research can be. And so, I think advocacy is a wonderful part of how doctors care for our patients. And it's something that is often difficult to know where to start, but once people get into advocacy, they can see that the power, the rewarding nature of it is attractive, and most people, once they get going, continue with that through the rest of their career. Dr. Monty Pal: So, I'll ask you to expand on that a little bit. We have a lot of our younger ASCO members listening to this podcast, folks that are just starting out their careers in clinical practice or academia. Where does that journey begin? How do you get to the point that you're testifying in front of Congress and taking on these bigger sort of stances for the oncology community? Dr. Jason Westin: Yeah, with anything in medicine and in our careers, you have to start somewhere. And often you start with baby steps before you get in front of a panel of senators or other high-profile engagement opportunities. But often the first setting for junior colleagues to be engaged is doing things – we call them "Hill Days" – but basically being involved in kind of low-stakes meetings where you're with a group of peers, some of whom have done this multiple times before, and can get engaged talking to members of representatives' offices, and doing so in a way where it's a natural conversation that you're telling a story about a patient in your clinic, or that you're telling a personal experience from a policy that impacted your ability to deliver optimal care. It sounds stressful, but once you're doing it, it's not stressful. It's actually kind of fun. And it's a way that you can get comfort and skill with a group of peers who are there and able to help you. And ASCO has a number of ways to do that, both at the federal level, there's the Hill Day where we each April have several hundred ASCO members travel to Capitol Hill. There's also state engagement that can be done, so-called visiting at home, when representatives from the U.S. Congress or from state legislators are back in district. You can meet with your own representatives on behalf of yourself, on behalf of your organization, and advocate for policies in a way that can be beneficial to your patients. But those initial meetings that are in the office often they're low stakes because you could be meeting not with the representative but with their staff. And that staff sometimes is as young or even younger than our junior colleagues. These sometimes can be people in their 20s, but they're often extremely knowledgeable, extremely approachable, and are used to dealing with people who are new to advocacy. But they actually help make decisions within the office. So it's not a waste of time. It's actually a super useful way to engage. So, it's that first step of anything in life. The activation energy is always high to do something new. But I'd encourage people who are listening to this podcast already having some level of interest about it to explore ways that they could engage more. Dr. Monty Pal: You know, I have to tell you, I'm going to riff on what you just said for a second. ASCO couldn't make it any easier, I think, for folks to participate and get involved. So, if you're listening to this and scratching your head and thinking, "Well, where do I begin? How do I actually sign on for that meeting with a local representative?" Go to the website. And I'll actually talk to our producer, Geraldine, to make sure we've got a link to that somewhere associated with this podcast after it's published, Jason, but I actually keep that on my browser and it's super easy. I check in there every now and then and see if there's any new policy or legislation that ASCO, you know, is sort of taking a stance on, and it gives me some fodder for conversation with my local representatives too. I mean, it's just an awesome, awesome vehicle. I'm going to segue right from there right to the issues. So, you and I are both at academic centers. You know, I think this is something that really pervades academia and enters into implications for general clinical practice. There's been this, you know, massive sort of proposal for decreased funding to the NCI and to the NIH and so forth. Tell us what ASCO is doing in that regard, and tell us perhaps how our community can help. Dr. Jason Westin: We live in interesting times, and I think that may be an understatement x 100. But obviously investments in research are things that when you're at an academic center, you see and feel that as part of your daily life. Members of Congress need to be reminded of that because there's a lot of other competing interests out there besides investing in the future through research. And being an elected representative is a hard job. That is something where you have to make difficult choices to support this, and that may mean not supporting that. And there's lots of good things where our tax dollars could be spent. And so, I'm sympathetic to the idea that there's not unlimited resources. However, ASCO has done an excellent job, and ASCO members have led the charge on this, of stating what research does, what is the benefit of research, and therefore why should this matter to elected representatives, to their staff, and to those people that they're elected to serve. And ASCO has led with a targeted campaign to basically have that message be conveyed at every opportunity to elected representatives. And each year on Hill Day, one of the asks that we have is to continue to support research: the NCI, NIH, ARPA-H, these are things that are always in the asks to make sure that there's appropriate funding. But effectively playing offense by saying, “It's not just a number on a sheet of paper, this is what it means to patients. This is what it means to potentially your loved ones in the future if you are in the opposite situation where you're not on the legislative side, but you're in the office receiving a diagnosis or receiving a difficult piece of news.” We only have the tools we have now because of research, and each breakthrough has been years in the making and countless hours spent funded through the engine of innovation: clinical research and translational research. And so ASCO continues to beat that drum. You mentioned earlier the . Just to bring that back again is a very useful, very easy tool to communicate to your elected representatives. When you sign up on the ASCO ACT website, you get emails periodically, not too much, but periodically get emails of, “This is a way you can engage with your lawmakers to speak up for this.” And as you said, Monty, they make it as easy as possible. You click the button, you type in your address so that it figures out who your elected representatives are, and then it will send a letter on your behalf after like five clicks to say, "I want you to support research. I want you to vote for this particular thing which is of interest to ASCO and by definition to members of ASCO." And so the ACT Network is a way that people listening can engage without having to spend hours and significant time, but just a few clicks can send that letter to a representative in Congress. And the question could be: does that matter? Does contacting your senator or your elected representative do anything? If all they're hearing is somebody else making a different argument and they're hearing over and over again from people that want investments in AI or investments in something else besides cancer research, whatever it is, they may think that there's a ground shift that people want dollars to be spent over here as opposed to at the NIH or NCI or in federally funded research. It is important to continue to express the need for federal funding for our research. And so, it really is important for folks to engage. Dr. Monty Pal: 100%. One of the things that I think is not often obvious to a lot of our listeners is where the support for clinical trials comes from. You know, you've obviously run the whole gamut of studies as have I. You know, we have our pharmaceutical company-sponsored studies, which are in a particular bucket. But I would say that there's a very important and critical subset of studies that are actually government funded, right? NCI-funded clinical trials. If you don't mind, just explain to our audience the critical nature of the work that's being done in those types of studies and if you can, maybe compare and contrast the studies that are done in that bucket versus perhaps the pharmaceutical bucket. Dr. Jason Westin: Both are critical, and we're privileged that we have pharma studies that are sponsored and federally funded clinical research. And I think that part of a healthy ecosystem for us to develop new breakthroughs has a need for both. The pharma sponsored studies are done through the lens of trying to get an approval for an agent that's of interest so that the pharma company can then turn around and use that outside of a clinical trial after an FDA approval. And so those studies are often done through the lens of getting over the finish line by showing some superiority over an existing treatment or in a new patient population. But they're done through that lens of kind of the broadest population and sometimes relatively narrow endpoints, but to get the approval so that then the drug can be widely utilized. Clinical trials done through cooperative groups are sometimes done to try and optimize that or to try and look at comparative things that may not be as attractive to pharma studies, not necessarily going for that initial approval, but the fine tuning or the looking at health outcomes or looking at ensuring that we do studies in representative populations that may not be as well identified on the pharma sponsored trials, but basically filling out the gaps in the knowledge that we didn't gain from the initial phase 3 trial that led to the approval. And so both are critical. But if we only do pharma sponsored trials, if we don't fund federally supported research and that dries up, the fear I have, and many others have, is that we're going to be lacking a lot of knowledge about the best ways to use these great new therapies, these new immune therapies, or in my team, we do a lot of clinical trials on CAR T-cell therapies. If we don't have federally funded research to do the important clinical studies, we'll be in the dark about the best ways to use these drugs, and that's going to be a terrible shame. And so we really do need to continue to support federal research. Dr. Monty Pal: Yeah, there are no softball questions on this podcast, but I think everybody would be hard pressed to think that you and I would come on here and say, "Well, no, we don't need as much money for clinical trials and NCI funding" and so forth. But I think a really challenging issue to tackle, and this is something we thought to ask you ahead of the podcast, is what to do about the general climate of, you know, whether it's academic research or clinical practice here that seems to be getting some of our colleagues thinking about moving elsewhere. I've actually talked to a couple of folks who are picking up and moving to Europe for a variety of considerations, other continents, frankly. The U.S. has always been a leader when it comes to oncology research and, one might argue, research in general. Some have the mindset these days that we're losing that footing a little bit. What's your perspective? Are you concerned about some of the trends that you're seeing? What does your crystal ball tell you? Dr. Jason Westin: I am highly concerned about this. I think as you said, the U.S. has been a leader for a long time, but it wasn't always. This is not something that's preordained that the world-leading clinical research and translational research will always be done in the United States. That is something that has been developed as an ecosystem, as an engine for innovation and for job development, new technology development, since World War II. That's something that through intentional investments in research was developed that the best and brightest around the world, if they could choose to go anywhere, you wanted them to come to work at universities and academic places within the United States. And I think, as you said, that's at risk if you begin to dry up the investment in research or if you begin to have less focus on being engaged in research in a way that is forward thinking, not just kind of maintaining what we do now or only looking at having private, for profit sponsored research. But if you don't have the investment in the basic science research and the translational research and the forward-thinking part of it, the fear is that we lose the advantage and that other countries will say, "Thank you very much," and be happy to invest in ways to their advantage. And I think as you mentioned, there are people that are beginning to look elsewhere. I don't think that it's likely that a significant population of researchers in the U.S. who are established and have careers and families – I don't think that we're going to see a mass exodus of folks. I think the real risk to me is that the younger, up-and-coming people in undergraduate or in graduate school or in medical school and are the future superstars, that they could either choose to go into a different field, so they decide not to go into what could be the latest breakthroughs for cancer patients but could be doing something in AI or something in a different field that could be attractive to them because of less uncertainty about funding streams, or they could take that job offer if it's in a different country. And I think that's the concern is it may not be a 2026 problem, but it could be a 2036 or a 2046 problem that we reap what we sow if we don't invest in the future. Dr. Monty Pal: Indeed, indeed. You know, I've had the pleasure of reviewing abstracts for some of our big international meetings, as I'm sure you've done in the past too. I see this trend where, as before, we would see the preponderance of large phase 3 clinical trials and practice setting studies being done here in the U.S., I'm seeing this emergence of China, of other countries outside of the U.S. really taking lead on these things. And it certainly concerns me. If I had to sort of gauge this particular issue, it's at the top of my list in terms of what I'm concerned about. But I also wanted to ask you, Jason, in terms of the issues that are looming over oncology from an advocacy perspective, what else really sort of keeps you up at night? Dr. Jason Westin: I'm quite concerned about the drug shortages. I think that's something that is a surprisingly evergreen problem. This is something that is on its face illogical that we're talking about the greatest engine for research in the world being the United States and the investment that we've made in drug development and the breakthroughs that have happened for patients all around the world, many of them happen in the United States, and yet we don't necessarily have access to drugs from the 1970s or 1980s that are cheap, generic, sterile, injectable drugs. This is the cisplatins and the vincristines and the fludarabine type medications which are not the sexy ones that you see the ads in the magazine or on TV at night. These are the backbone drugs for many of our curative intent regimens for pediatrics and for heme malignancies and many solid tumors. And the fact that that's continuing to be an issue is, in my opinion, a failure to address the root causes, and those are going to require legislative solutions. The root causes here are basically a race to the bottom where the economics to invest in quality manufacturing really haven't been prioritized. And so it's a race to the cheapest price, which often means you undercut your competitor, and when you don't have the money to invest in good manufacturing processes, the factory breaks down, there's no alternative, you go into shortage. And this has been going on for a couple of decades, and I don't think there's an end in sight until we get a serious solution proposed by our elected officials. That is something that bothers me in the ways where we know what we should be doing for our patients, but if we don't have the drugs, we're left to be creative in ways we shouldn't have to do to figure out a plan B when we've got curative intent therapies. And I think that's a real shame. There's obviously a lot of other things that are concerning related to oncology, but something that I have personally had experience with when I wanted to give a patient a CAR T-cell, and we don't have a supply of fludarabine, which is a trivial drug from decades ago in terms of the technology investments in genetically modified T-cells, to not then have access to a drug that should be pennies on the dollar and available at any time you want it is almost like the Air Force investing in building the latest stealth bomber, but then forgetting to get the jet fuel in a way that they can't use it because they don't have the tools that they need. And so I think that's something that we do need to have comprehensive solutions from our elected officials. Dr. Monty Pal: Brilliantly stated. I... /episode/index/show/ascodaily/id/39155110

What Frontline Treatment Should Be Used in Advanced Ovarian Cancer? 11/20/2025

What Frontline Treatment Should Be Used in Advanced Ovarian Cancer? Dr. Linda Duska and Dr. Kathleen Moore discuss key studies in the evolving controversy over radical upfront surgery versus neoadjuvant chemotherapy in advanced ovarian cancer. TRANSCRIPT Dr. Linda Duska: Hello, and welcome to the ASCO Daily News Podcast. I am your guest host, Dr. Linda Duska. I am a professor of obstetrics and gynecology at the University of Virginia School of Medicine. On today's episode, we will explore the management of advanced ovarian cancer, specifically with respect to a question that has really stirred some controversy over time, going all the way back more than 20 years: Should we be doing radical upfront surgery in advanced ovarian cancer, or should we be doing neoadjuvant chemotherapy? So, there was a lot of hype about the study, also called ENGOT ov33/AGO-OVAR OP7, a Phase 3 randomized study that compares upfront surgery with neoadjuvant chemotherapy followed by interval surgery. So, I want to talk about that study today. And joining me for the discussion is Dr. Kathleen Moore, a professor also of obstetrics and gynecology at the University of Oklahoma and the deputy director of the Stephenson Cancer Center, also at the University of Oklahoma Health Sciences. Dr. Moore, it is so great to be speaking with you today. Thanks for doing this. Dr. Kathleen Moore: Yeah, it's fun to be here. This is going to be fun. Dr. Linda Duska: FYI for our listeners, both of our full disclosures are available in the transcript of this episode. So let's just jump right in. We already alluded to the fact that the study addresses a question we have been grappling with in our field. Here's the thing, we have four prior randomized trials on this exact same topic. So, share with me why we needed another one and what maybe was different about this one? Dr. Kathleen Moore: That is, I think, the key question. So we have to level-set kind of our history. Let's start with, why is this even a question? Like, why are we even talking about this today? When we are taking care of a patient with newly diagnosed ovarian cancer, the aim of surgery in advanced ovarian cancer ideally is to prolong a patient's likelihood of disease-free survival, or if you want to use the term "remission," you can use the term "remission." And I think we can all agree that our objective is to improve overall survival in a way that also does not compromise her quality of life through surgical complications, which can have a big effect. The standard for many decades, certainly my entire career, which is now over 20 years, has been to pursue what we call primary cytoreductive surgery, meaning you get a diagnosis and we go right to the operating room with a goal of achieving what we call "no gross residual." That is very different – in the olden days, you would say "optimal" and get down to some predefined small amount of tumor. Now, the goal is you remove everything you can see. The alternative strategy to that is neoadjuvant chemotherapy followed by interval cytoreductive surgery, and that has been the, quote-unquote, "safer" route because you chemically cytoreduce the cancer, and so, the resulting surgery, I will tell you, is not necessarily easy at all. It can still be very radical surgeries, but they tend to be less radical, less need for bowel resections, splenectomy, radical procedures, and in a short-term look, would be considered safer from a postoperative consideration. Dr. Linda Duska: Well, and also maybe more likely to be successful, right? Because there's less disease, maybe, theoretically. Dr. Kathleen Moore: More likely to be successful in getting to no gross residual. Dr. Linda Duska: Right. Yeah, exactly. Dr. Kathleen Moore: I agree with that. And so, so if the end game, regardless of timing, is you get to no gross residual and you help a patient and there's no difference in overall survival, then it's a no-brainer. We would not be having this conversation. But there remains a question around, while it may be more likely to get to no gross residual, it may be, and I think we can all agree, a less radical, safer surgery, do you lose survival in the long term by this approach? This has become an increasing concern because of the increase in rates of use of neoadjuvant, not only in this country, but abroad. And so, you mentioned the four prior studies. We will not be able to go through them completely. Dr. Linda Duska: Let's talk about the two modern ones, the two from 2020 because neither one of them showed a difference in overall survival, which I think we can agree is, at the end of the day, yes, PFS would be great, but OS is what we're looking for. Dr. Kathleen Moore: OS is definitely what we're looking for. I do think a marked improvement in PFS, like a real prolongation in disease-free survival, for me would be also enough. A modest improvement does not really cut it, but if you are really, really prolonging PFS, you should see that- Dr. Linda Duska: -manifest in OS. Dr. Kathleen Moore: Yeah, yeah. Okay. So let's talk about the two modern ones. The older ones are and , which I think we've talked about. The two more modern ones are and . So, SCORPION was interesting. SCORPION was a very small study, though. So one could say it's underpowered. 170 patients. And they looked at only patients that were incredibly high risk. So, they had to have a Fagotti score, I believe, of over 9, but they were not looking at just low volume disease. Like, those patients were not enrolled in SCORPION. It was patients where you really were questioning, “Should I go to the OR or should I do neoadjuvant? Like, what's the better thing?” It is easy when it's low volume. You're like, "We're going." These were the patients who were like, "Hm, you know, what should I do?" High volume. Patients were young, about 55. The criticism of the older studies, there are many criticisms, but one of them is that, the criticism that is lobbied is that they did not really try. Whatever surgery you got, they did not really try with median operative times of 180 minutes for primary cytoreduction, 120 for neoadjuvant. Like, you and I both know, if you're in a big primary debulking, you're there all day. It's 6 hours. Dr. Linda Duska: Right, and there was no quality control for those studies, either. Dr. Kathleen Moore: No quality control. So, SCORPION, they went 451-minute median for surgery. Like, they really went for it versus four hours and then 253 for the interval, 4 hours. They really went for it on both arms. Complete gross resection was achieved in 50% of the primary cytoreduced. So even though they went for it with these very long surgeries, they only got to the goal half the time. It was almost 80% in the interval group. So they were more successful there. And there was absolutely no difference in PFS or OS. They were right about 15 months PFS, right about 40 months OS. JCOG0602, of course, done in Japan, a big study, 300 patients, a little bit older population. Surprisingly more stage IV disease in this study than were in SCORPION. SCORPION did not have a lot of stage IV, despite being very bulky tumors. So a third of patients were stage IV. They also had relatively shorter operative times, I would say, 240 minutes for primary, 302 for interval. So still kind of short. Complete gross resection was not achieved very often. 30% of primary cytoreduction. That is not acceptable. Dr. Linda Duska: Well, so let's talk about TRUST. What was different about TRUST? Why was this an important study for us to see? Dr. Kathleen Moore: So the criticism of all of these, and I am not trying to throw shade at anyone, but the criticism of all of these is if you are putting surgery to the test, you are putting the surgeon to the test. And you are assuming that all surgeons are trained equally and are willing to do what it takes to get someone to no gross residual. Dr. Linda Duska: And are in a center that can support the post-op care for those patients. Dr. Kathleen Moore: Which can be ICU care, prolonged time. Absolutely. So when you just open these broadly, you're assuming everyone has the surgical skills and is comfortable doing that and has backup. Everybody has an ICU. Everyone has a blood bank, and you are willing to do that. And that assumption could be wrong. And so what TRUST said is, "Okay, we are only going to open this at centers that have shown they can achieve a certain level of primary cytoreduction to no gross residual disease." And so there was quality criteria. It was based on – it was mostly a European study – so ESGO criteria were used to only allow certified centers to participate. They had to have a surgical volume of over 36 cytoreductive surgeries per year. So you could not be a low volume surgeon. Your complete resection rates that were reported had to be greater than 50% in the upfront setting. I told you on the JCOG, it was 30%. Dr. Linda Duska: Right. So these were the best of the best. This was the best possible surgical situation you could put these patients in, right? Dr. Kathleen Moore: Absolutely. And you support all the things so you could mitigate postoperative complications as well. Dr. Linda Duska: So we are asking the question now again in the ideal situation, right? Dr. Kathleen Moore: Right. Dr. Linda Duska: Which, we can talk about, may or may not be generalizable to real life, but that's a separate issue because we certainly don't have those conditions everywhere where people get cared for with ovarian cancer. But how would you interpret the results of this study? Did it show us anything different? Dr. Kathleen Moore: I am going to say how we should interpret it and then what I am thinking about. It is a negative study. It was designed to show improvement in overall survival in these ideal settings in patients with FIGO stage IIIB and C, they excluded A, these low volume tumors that should absolutely be getting surgery. So FIGO stage IIIB and C and IVA and B that were fit enough to undergo radical surgery randomized to primary cytoreduction or neoadjuvant with interval, and were all given the correct chemo. Dr. Linda Duska: And they were allowed bevacizumab and PARP, also. They could have bevacizumab and PARP. Dr. Kathleen Moore: They were allowed bevacizumab and PARP. Not many of them got PARP, but it was distributed equally, so that would not be a confounder. And so that was important. Overall survival is the endpoint. It was a big study. You know, it was almost 600 patients. So appropriately powered. So let's look at what they reported. When they looked at the patients who were enrolled, this is a large study, almost 600 patients, 345 in the primary cytoreductive arm and 343 in the neoadjuvant arm. Complete resection in these patients was 70% in the primary cytoreductive arm and 85% in the neoadjuvant arm. So in both arms, it was very high. So your selection of site and surgeon worked. You got people to their optimal outcome. So that is very different than any other study that has been reported to date. But what we saw when we looked at overall survival was no statistical difference. The median was, and I know we do not like to talk about medians, but the median in the primary cytoreductive arm was 54 months versus 48 months in the neoadjuvant arm with a hazard ratio of 0.89 and, of course, the confidence interval crossed one. So this is not statistically significant. And that was the primary endpoint. Dr. Linda Duska: I know you are getting to this. They did look at PFS, and that was statistically significant, but to your point about what are we looking for for a reasonable PFS difference? It was about two months difference. When I think about this study, and I know you are coming to this, what I thought was most interesting about this trial, besides the fact that the OS, the primary endpoint was negative, was the subgroup analyses that they did. And, of course, these are hypothesis-generating only. But if you look at, for example, specifically only the stage III group, that group did seem to potentially, again, hypothesis generating, but they did seem to benefit from upfront surgery. And then one other thing that I want to touch on before we run out of time is, do we think it matters if the patient is BRCA germline positive? Do we think it matters if there is something in particular about that patient from a biomarker standpoint that is different? I am hopeful that more data will be coming out of this study that will help inform this. Of course, unpowered, hypothesis-generating only, but it's just really interesting. What do you think of their subset analysis? Dr. Kathleen Moore: Yeah, I think the subsets are what we are going to be talking about, but we have to emphasize that this was a negative trial as designed. Dr. Linda Duska: Absolutely. Yes. Dr. Kathleen Moore: So we cannot be apologists and be like, "But this or that." It was a negative trial as designed. Now, I am a human and a clinician, and I want what is best for my patients. So I am going to, like, go down the path of subset analyses. So if you look at the stage III tumors that got complete cytoreduction, which was 70% of the cases, your PFS was almost 28 months versus 21.8 months. Dr. Linda Duska: Yes, it becomes more significant. Dr. Kathleen Moore: Yeah, that hazard ratio is 0.69. Again, it is a subset. So even though the P value here is statistically significant, it actually should not have a P value because it is an exploratory analysis. So we have to be very careful. But the hazard ratio is 0.69. So the hypothesis is in this setting, if you're stage III and you go for it and you get someone to no gross residual versus an interval cytoreduction, you could potentially have a 31% reduction in the rate of progression for that patient who got primary cytoreduction. And you see a similar trend in the stage III patients, if you look at overall survival, although the post-progression survival is so long, it's a little bit narrow of a margin. But I do think there are some nuggets here that, one of our colleagues who is really one of the experts in surgical studies, Dr. Mario Leitao, posted this on X, and I think it really resonated after this because we were all saying, "But what about the subsets?" He is like, "It's a negative study." But at the end of the day, you are going to sit with your patient. The patient should be seen by a GYN oncologist or surgical oncologist with specialty in cytoreduction and a medical oncologist, you know, if that person does not give chemo, and the decision should be made about what to do for that individual patient in that setting. Dr. Linda Duska: Agreed. And along those lines, if you look carefully at their data, the patients who had an upfront cytoreduction had almost twice the risk of having a stoma than the patients who had an interval cytoreduction. And they also had a higher risk of needing to have a bowel resection. The numbers were small, but still, when you look at the surgical complications, as you've already said, they're higher in the upfront group than they are in the interval group. That needs to be taken into account as well when counseling a patient, right? When you have a patient in front of you who says to you, "Dr. Moore, you can take out whatever you want, but whatever you do, don't make me a bag." As long as the patient understands what that means and what they're asking us to do, I think that we need to think about that. Dr. Kathleen Moore: I think that is a great point. And I have definitely seen in our practice, patients who say, "I absolutely would not want an ostomy. It's a nonstarter for me.” And we do make different decisions. And you have to just say, "That's the decision we've made," and you kind of move on, and you can't look back and say, "Well, I wish I would have, could have, should have done something else." That is what the patient wants. Ultimately, that patient, her family, autonomous beings, they need to be fully counseled, and you need to counsel that patient as to the site that you are in, her volume of disease, and what you think you can achieve. In my opinion, a patient with stage III cancer who you have the site and the capabilities to get to no gross residual should go to the OR first. That is what I believe. I do not anymore think that for stage IV. I think that this is pretty convincing to me that that is probably a harmful thing. However, I want you to react to this. I think I am going to be a little unpopular in saying this, but for me, one of the biggest take-homes from TRUST was that whether or not, and we can talk about the subsets and the stage III looked better, and I think it did, but both groups did really well. Like, really well. And these were patients with large volume disease. This was not cherry-picked small volume stage IIIs that you could have done an optimal just by doing a hysterectomy. You know, these were patients that needed radical surgery. And both did well. And so what it speaks to me is that anytime you are going to operate on someone with ovary, whether it be frontline, whether it be a primary or interval, you need a high-volume surgeon. That is what I think this means to me. Like, I would want high volume surgeon at a center that could do these surgeries, getting that patient, my family member, me, to no gross residual. That is important. And you and I are both in training centers. I think we ought to take a really strong look at, are we preparing people to do the surgeries that are necessary to get someone to no gross residual 70% and 85% of the time? Dr. Linda Duska: We are going to run out of time, but I want to address that and ask you a provocative question. So, I completely agree with what you said, that surgery is important. But I also think one of the reasons these patients in this study did so well is because all of the incredible new therapies that we have for patients. Because OS is not just about surgery. It is about surgery, but it is also about all of the amazing new therapies we have that you and others have helped us to get through clinical research. And so, how much of that do you think, like, for example, if you look at the PFS and OS rates from CHORUS and EORTC, I get it that they're, that they're not the same. It's different patients, different populations, can't do cross-trial comparisons. But the OS, as you said, in this study was 54 months and 48 months, which is, compared to 2010, we're doing much, much better. It is not just the surgery, it is also all the amazing treatment options we have for these patients, including PARP, including MIRV, including lots of other new therapies. How do you fit that into thinking about all of this? Dr. Kathleen Moore: I do think we are seeing, and we know this just from epidemiologic data that the prevalence of ovarian cancer in many of the countries where the study was done is increasing, despite a decrease in incidence. And why is that? Because people are living longer. Dr. Linda Duska: People are living longer, yeah. Dr. Kathleen Moore: Which is phenomenal. That is what we want. And we do have, I think, better supportive care now. PARP inhibitors in the frontline, which not many of these patients had. Now some of them, this is mainly in Europe, will have gotten them in the first maintenance setting, and I do think that impacts outcome. We do not have that data yet, you know, to kind of see what, I would be really interested to see. We do not do this well because in ovarian cancer, post-progression survival can be so long, we do not do well of tracking what people get when they come off a clinical trial to see how that could impact – you know, how many of them got another surgery? How many of them got a PARP? I think this group probably missed the ADC wave for the most part, because this, mirvetuximab is just very recently available in Europe. Dr. Linda Duska: Unless they were on trial. Dr. Kathleen... /episode/index/show/ascodaily/id/38898180

Managing Immune-Related Toxicities in Oncology 11/06/2025

Managing Immune-Related Toxicities in Oncology Dr. Monty Pal and Dr. Pauline Funchain discuss the latest efforts to diagnose, prevent, and treat the series of immune-related adverse events that have emerged in the era of immunotherapy. TRANSCRIPT Dr. Monty Pal: Hello, and welcome to the ASCO Daily News Podcast. I am Monty Pal, a medical oncologist, professor and vice chair of medical oncology at the City of Hope Comprehensive Cancer Center in Los Angeles, California. Now, it is probably no surprise to this audience that immunotherapy has transformed the treatment landscape for multiple cancer types. It remains a pillar of modern oncology. Having said that, I think we have all been baffled by certain toxicities that we run into in the clinic. Today, I am delighted to be joined by Dr Pauline Funchain to discuss some of the checkpoint inhibitor toxicities that people struggle with most. And we will also touch on some side effects of immunotherapy beyond checkpoint inhibitors: CAR-T cells, bispecifics, so on and so forth. Dr Funchain is a dear friend, and she is an associate professor and associate director of cancer research training and education at the Stanford Cancer Institute. She is co-director of the Immunotherapy Toxicity Program and the Skin Cancer Genomics Program at Stanford, where she also serves as associate program director of hematology and oncology fellowship. Dr. Funchain is also the co-founder of ASPIRE, and we are going to talk about that a little bit today, the Alliance for the Support and Prevention of Immune-Related Events. FYI for listeners, if you are interested in our disclosures, they are available at the transcript of this episode. Pauline, thanks so much for joining us today. Dr. Pauline Funchain: Monty, thank you for this invitation. It is always great to talk. Dr. Monty Pal: So, for the audience, Pauline and I know each other from my days as a fellow at City of Hope. She was a resident at Harbor UCLA and a stellar resident at that. It has just been amazing to sort of see your career grow and blossom and to witness all the cool things that you are doing. ASPIRE, in particular, sort of caught my eye. So again, for listeners, this is the Alliance for the Support and Prevention of Immune-Related Events. Can you tell us a little bit briefly about the genesis of that, how that came about? Dr. Pauline Funchain: So, there was a bunch of us who were really struggling, I mean, all of us have struggled with these immune-related adverse events, these irAEs. You know, they are new disease states, and even though they look like autoimmune diseases, they tend to need a whole lot more steroid than autoimmune diseases do and they do not totally present in the same way. And in fact, you know, Triple-M, or Triple-M overlap syndrome, is a completely new irAE, a new immune state that we have never had before the advent of checkpoint inhibitor. And so a Triple-M, for those of you who are not as familiar, that is the constellation of myocarditis, myositis, and myasthenia gravis, something that never occurs as a natural autoimmune disease. So we were starting to realize that there were some major differences with these irAEs and autoimmune diseases. We could not treat them the right way. We really needed to learn more about them. And a bunch of us who had interest in this said, "Look, we really need to be all in one space to talk about what we are doing," because all of our treatments were our own little homegrown brews, and we needed to really get together and understand how to treat these things, how to diagnose them, and then learn more about them. So, Dr. Alexa Meara from Ohio State, Dr. Kerry Reynolds from Mass Gen, we put together this research consortium, brought together all of our irAE friends, got our best subspecialists together in a research consortium, which is now only about a year and a half old. And we made this research consortium, the Alliance for Support of Prevention of Immune-Related Events, and we reached out to ASCO, and ASCO was so kind to grant us a [Alliance for Support and Prevention of Immune-Related adverse Events (ASPIRE)] . So we met for the first time as a Community of Practice at the ASCO Annual Meeting just this past June and really got an ASCO community together to really think about how to again, diagnose, prevent, treat irAEs. Dr Monty Pal: This is interesting to me. The ASCO Community of Practice phenomenon is something that I was not super familiar with. Can you explain to our listenership what is the ASCO Community of Practice model? If you have particular interests, how do you sort of get one started? Dr Pauline Funchain: Yeah, so ASCO has an entire page on their . There are multiple Community of Practice groups or COPs. There are ones for Supportive Oncology and Survivorship. There is Women in Oncology. There is a group for International Medical Graduates. And there is about, I think 10 or 12 now that have a physical presence at ASCO but also a virtual presence on the ASCO Community of Practice site. So, if you were interested in any one of these, and you can see them on the ASCO Communities of Practice sites, you would ask to become a member. Once granted membership, then there is a whole webpage of postings and conversations that people can have. You can get email digests of conversations that happen on the website, and then you can anchor it with in-person participation at the Annual Meeting. Dr Monty Pal: That is awesome, and I can think of so many different foci within oncology that really sort of deserve a Community of Practice. This definitely being one of them. You know, it strikes me as being so interesting. I mean, the checkpoint inhibitors have been around for a while now. I think when you and I were in training, gosh, back then, these were just a little bit of a pipe dream, right? But having said that, I would probably say that more than half of my kidney cancer practice is either on checkpoint inhibitors, and the vast majority have been on one at some point in their past, right? With that in mind, you know, we have all treated a lot of patients with these drugs. Why is it that we still struggle to manage the toxicities? And just to take that one step further, what are some of the toxicities that, perhaps through ASPIRE or through your experience, people struggle with the most? Dr Pauline Funchain: So, I think we are still struggling with these because again, they are new disease states, right? This is what we all experienced with COVID, a brand-new virus and a brand-new syndrome. We now have 20-plus of these as irAEs. And what we have realized about them is the immune activation that happens with these is so much more than what we have seen with autoimmune diseases. So for instance, if you have a Crohn's or ulcerative colitis, you will top out at 40 to 60 milligrams of prednisone if a Crohn's flare or ulcerative colitis flare happens. But for our severe IR colitises, you know, it is at least 1 mg per kg, often goes up to 2 mg per kg. We, in some cases, have done 1 gram pulses if we are worried that somebody is going to perforate. So that was sort of like the first 5 years of treating irAE, and then now in the sort of second 5 years of treating irAE, we have realized that that is a lot of immunosuppression, and we might be able to get away with less with the newer biologics that are on board. So, we are struggling to try to get the data for some of these irAEs that we knew, we have known for a while, but to try to get newer treatments that may immunosuppress less so that you may still be able to retain that tumor response. And in fact, some of the preclinical studies suggest that some of these biologics may actually synergize with the immunotherapy and actually make the immunotherapy more effective from a tumor perspective and calm down the irAE as sort of the bystander effect. So we are still trying to optimize those. Getting up trials in the space has been very difficult. That is one of the reasons for the genesis of ASPIRE because we realized we needed to band together to have a bigger voice in that realm. Then there are other things that are brand new. So we talked about Triple-M. So Triple-M, again, with Triple-M or any myocarditis or myasthenia, I mean, there is about a 50% chance of death from irAE based on the literature. I think we are getting better at recognizing this, and so at Stanford we have some data to say that if you serially follow troponin, that maybe your outcomes are better. You can potentially lower the percentage of cases that are fatal because you can catch them early. I mean, this is all preliminary data, but again, these are all things that are evolving, and we do not all have the right answer. I mean, even the serial troponin thing, I think, is pretty controversial. And in fact, at one of our quarterly Zoom meetings that we are doing in ASPIRE in December is going to sort of flush out that controversy about serial troponin measuring and what is the best thing to use? Would you use something like abatacept or would you use ruxolitinib? Which one is better? I think there is a lot of controversy still about these things. Dr Monty Pal: You have really piqued my curiosity here because you think about the cons of treating irAEs, right? And I worry exactly about what you had mentioned, right, which is, "Gosh, what is going on with this tumor in terms of immunosuppression?" But you think about some of the newer agents, you mentioned ruxolitinib, I have heard of dasatinib, for instance, in this setting. Frankly speaking, a lot of these, as you point out, are really thought of as being also anticancer drugs. So you have really got me thinking about the potential synergy between perhaps suppressing an irAE and augmenting antitumor activity, which I think is very interesting. Am I on the right track with that? Dr Pauline Funchain: I think so, but you will find that a lot of people will not even go there because they are worried about how much immunosuppression you are going to cause. I am at heart a geneticist, but I think an immunologist will happily tell you that the immune system is very complex. There are multiple pathways, and these drugs do not all target the same immune pathways. So if we understand a little bit more about the pathways we are targeting and pick apart the pathways that are really, really tumor relevant and the other pathways that are not tumor relevant, you may be able to piece together a better marriage of tumor response and irAE control. Dr Monty Pal: Kind of on this topic, and again, leaning on your background in genetics, where are we in terms of predicting these irAEs? I mean, you would think the holy grail would be picking out a snip or something of this for it, right, that could potentially identify that patient who is going to get Triple-M or, you know, at the very least a significant high-grade irAE event. Are we anywhere closer to that in 2025? Dr Pauline Funchain: There have been data published. There have been some big GWAS studies. All of the effect sizes are pretty small. So there are some prediction algorithms, but none of them are clinically useful. And I think when you look at the odds ratios, they will increase risk by maybe 20%. I think one of the things that we found in a very small series and supported anecdotally is something as easy as family history of autoimmune disease is probably more predictive at this point than any of those types of markers. I think we will get there, but we are not anywhere near where we would like to be. Things like TMB also, actually, there is some good data about higher TMB, higher risk of irAE too. Dr Monty Pal: Interesting. I see all this data coming through, IL-8 polymorphisms, etc. And I just wondered if any of that was ready for prime time. But I mean, this is a good message for the practicing clinician. Sounds like we are not quite there yet. And I could probably keep you on for another entire podcast to talk about this topic, but let us see if we can at least skim the surface. I never thought I would see the day when BiTEs and CAR-Ts were entering into my kidney cancer practice, but in fact, it is really become central to a lot of our clinical trials in RCC these days. I would be lying if I did not say that I was not struggling with the toxicities and so forth associated with these drugs. Can you give us a quick primer, maybe just good resources that people can go to for managing toxicity with BiTEs and with CAR and with some of these novel therapeutic modalities that we are using in the oncology clinics? Dr Pauline Funchain: I know there is a recently published toxicity manual for BiTEs in hematologic malignancies, I think it was in Blood. CAR-T is covered in many irAE guidelines. So ASCO guidelines actually has a , and I would be remiss not to point out that actually ASCO has a, I am a little biased, but a wonderful that is actually being updated as we speak. We are hoping for publication next year. I find the format of that, there are many guidelines out there, actually. There is , , has a guideline for irAE, but I find the formatting of the ASCO guideline to be much easier to flip through during clinic, just because of the visual format of the tables. But that is going to be updated next year. And with CAR-T, there is now multiple publications also in terms of guidelines. But what I will say about bispecifics and CAR-T, so they have very similar toxicities in terms of the cytokine release and also with the ICANS, so the neurotoxicity. But what we have been finding that is really interesting with BiTEs and CAR-T, and actually even with TIL, cytokine release is very similar to some of the IL-2 toxicities but not identical that we see with TIL treatment. But now we are starting to see overlap. So patients who have been treated with immunotherapy and then go on to get a bispecific or then go on to get TIL, so I have seen some colitises that have occurred after the fact. Some of the newer CAR-Ts without checkpoint have been causing some really interesting, probably not in a good way, but interesting biologically, colitises that are really refractory. So we are starting to see some overlap, and again, I think this field is just evolving constantly. Dr Monty Pal: Yeah, no, I almost think I need to go back to that fellowship that you and I did together 20 years ago and, you know, and see if I could repeat some coursework on CAR-T management. You know, Pauline, I could probably keep you on the horn for hours, but this has just been terrific. Thank you so much for sharing all of your insights with us today on the ASCO Daily News Podcast. Dr Pauline Funchain: Thank you for the invitation. It was wonderful to talk about this, and it was wonderful to catch up a little bit, Monty. Dr Monty Pal: Same here, same here.

Key Takeaways From the 2025 ASCO Quality Care Symposium 10/16/2025

Key Takeaways From the 2025 ASCO Quality Care Symposium Dr. Monty Pal and Dr. Fumiko Chino discuss several of the top abstracts presented at the 2025 ASCO Quality Care Symposium, including research on federally funded clinical trials and financial reimbursement for trial participation. TRANSCRIPT Dr. Monty Pal: Hello, and welcome to the ASCO Daily News Podcast. I am your host, Dr. Monty Pal. I am a medical oncologist, professor, and vice chair of academic affairs at the City of Hope Comprehensive Cancer Center in Los Angeles. Today, we are highlighting key abstracts that were presented at the 2025 ASCO Quality Care Symposium. I am delighted to be joined today by the chair of this year's meeting, Dr. Fumiko Chino. Dr. Chino is an associate professor in radiation oncology at MD Anderson Cancer Center with a research focus on access, affordability, and equity. She is also a consultant editor of JCO Oncology Practice and the host of the . I have got to listen to that. Dr. Chino, welcome, and thanks so much for being on the podcast today. Dr. Fumiko Chino: I am overjoyed to be here, and absolutely, you should take a listen. Dr. Monty Pal: Definitely. And FYI for listeners, our full disclosures are all available in the transcript of this episode, so do have a look if you are inclined. Now, we have really seen some fantastic advances in health services and quality and supportive care, digital health, and beyond. There are some great abstracts that were presented at this year's meeting. I have actually picked a couple that I am particularly interested in and that I believe you share my interest in as well. So, the first is an abstract actually from my friends at SWOG (). So, this was a terrific abstract from Joe Unger and Michael LeBlanc and Dawn Hershman. And this, I think, really hits on a very, very key issue right now, which is the benefit of federally funded trials. Do you mind just kind of spelling out some of the observations from what I think is a really brilliant piece of work? Dr. Fumiko Chino: Absolutely, and I think Dr. Unger's work is really important for our current funding environment. I think that this research is really essential to do to show the role of federal sponsorship in the design and conduct of clinical trials. Because what they did was really look at a landscape analysis over the last 20 years looking at funding and were able to show quite clearly that federal funding really matters for advancing the science in cancer care. So what they showed was that the federal funding was more commonly essential for early-stage clinical trials, so those phase 1, phase 2 trials that really help advance the science. And that federal funding was really essential for multimodality drug combinations, combinations with drug and surgery, combinations with drug and radiation. Those trials were much more likely to be federal funded. And then the last thing is that they showed that the patients that are, I think, the largest at risk for gaps in care who really need the advancements in science that keep U.S. health care amazing and wonderful and world-leading, so the kids, the pediatric patients, the patients with rare cancers, and the patients actually that could benefit from de-escalation or right-sizing of treatment, they were also all more likely to have federal funding. So I think this research that was presented really shows that if, unfortunately, current status of restricted federal funding continues, that we are going to lose out in terms of the next generation of cancer cures, cancer de-escalations, and the type of combination treatments that make advancements in science. Dr. Monty Pal: Indeed. You know, I always point to Joe Unger's paper, and I think it is in JAMA Oncology, right, that showed life-years gained from NCI trials. It is such an important piece of work. I think this is a really nice complement to that, isn’t it, to show the specific areas that otherwise would be, am I right in saying, kind of largely untouched? Dr. Fumiko Chino: I think you are right in that what we know from what industry will sponsor versus what the federal government will sponsor, that the federal government really helps make up the gap to really make those advancements that save lives, that lead to more birthdays, that advance our knowledge and our capacity for providing more cures and more successful futures for our patients. I always like pointing to the de-escalation research, which is, and this is not to dig pharma, but no pharmaceutical company is going to run a trial that says you can give less of their drug, right? It just does not make sense for the business end of the science. And so, thinking about how to right-size treatments, how to do more with less, that really is the purview of the federal government. Dr. Monty Pal: Absolutely. Absolutely. I am going to shift gears here and bring up another abstract that I found to be quite intriguing, and this relates to reimbursement of expenses, et cetera, for clinical trials. This is an abstract from Courtney Williams and team. It brings to mind the importance, I think, of recognizing the hardships that patients take on by clinical trials, but I also would love for you to comment on that sort of fine line between reimbursement for expenses and then, you know, sort of undue enticement. It is a challenging balance there. But give me your reflections on this abstract. Dr. Fumiko Chino: Absolutely. You are speaking about Dr. Williams' from the Alabama group, and Alabama actually has this incredible group of health services researchers which is, are doing really important work in this space. What this trial shows is that, you know, it is a small pilot study, it is 30-something patients that received some support primarily for their travel and additional expenses related to their clinical trial participation for breast cancer. It showed that the money helps, and I think what we all know is that it is expensive to participate in clinical trials. It requires additional visits. It often requires some significant travel burden for our patients, and I do not feel that money reimbursement for clinical trial expenses is an inducement. Nobody participates in a clinical trial to get the money for their gas, right? We know that our patients are making some pretty significant sacrifices in order to participate in clinical trials, and what this type of program does is just actually reimburse them for their outlaying of funds. And I loved this trial because the patients were actually given $1,000 a month for the first 4 months of their trial participation, and what the study showed is that the patients were using it for things like travel-related food, for things like transportation, caregiver expenses, or even some of their out-of-pocket medical expenses like cost sharing or prescriptions. And that they said that overall, the reimbursement really made a difference in terms of their capacity for staying on the clinical trial. Because we know our clinical trials really are not able to enroll the full diversity of patients that often have a disease, and that the patients that are at biggest risk for a health care disparity or a gap in care are also the least likely to enroll in a clinical trial. Programs like this are an essential part of showing how financial toxicity can be overcome with pretty straightforward assistance to patients to help reimburse them for the things that they are already taking out of their pocket, for parking costs, for that $10 soup that they buy at the cancer center, for those additional expenses that we are, unfortunately, putting on them. Dr. Monty Pal: Very well said. And you know, I have started to dabble in clinical trials looking at CAR T-cell therapies for kidney cancer, and I have to tell you, it is just insane the amount of cost that a patient would have to take on to comply with the stipulations for some of these novel therapies. We require that they stay within 30 minutes of the facility for 28 days, and unless we are compensating for some of that, I mean, how can one afford a hotel stay that is that long? I mean, it is just, it is unprecedented, and it would certainly provide a huge barrier to many patients who would otherwise enroll. Really well said. I also wanted to bring up another financially driven topic, and treating renal cell, again, I would say the vast majority, 90% plus of my patients in clinic are on oral drug therapies. And I cannot tell you how often a patient will show up in my practice and say, "Doc, I have got 15 days out of this 30-day prescription left. What do I do with it?" You know, or some come with pill bottles from a deceased loved one. And it is so frustrating to say, "Take it to the pharmacy and they will just get rid of it for you." But sounds like there is an abstract from Dr. Mackler, , that seems to address this topic quite well. Am I right? Dr. Fumiko Chino: Absolutely. This presentation, I was the most excited about seeing because this group, which helps run a cancer drug repository, theirs is called YesRx, presented their data from the last approximately two years of running this repository, and they were able to show incredible benefit for their patients in Michigan. And it is a really straightforward program. It is run by pharmacists. It has support from the legislation in Michigan. And what they were able to show is that they repurposed medications that would otherwise have been discarded. They delivered them directly to the oncologist, which then actually dispersed them to the patients. They helped 1,000 patients in less than two years. They saved them millions of dollars, over $15 million presented in the abstract. And it is just a win-win-win because I know that patients actually, and sometimes patient caregivers, they feel very sad to have spent a lot of money out of pocket for their medication, and then if they have a dose reduction or, obviously, you know, if the surviving spouse then has to get rid of their medication, just dispose of them, it is very disheartening. And this is a way of kind of reclaiming power for patients. So they were able to accept donations from all over the state of Michigan and then also help over 1,000 patients. And so, it is a phenomenal program. Dr. Monty Pal: Just wild when I came across the dollar amounts, right, that they were saving. It just, it seems like a place that, you know, we just have to look, as cancer centers, right, and really take this on. Just brilliant. On that same theme of cost savings and so forth, you know, I think there has been a lot of focus on what recent policies have done in the context of us having access to therapies and so forth. And one of the topics that has come up is the Inflation Reduction Act and how changes pertaining to the IRA have really played a role in one's ability to take on some of these expensive prescriptions. And I believe John Lin and colleagues tackled that issue in . Could you comment on that, Fumiko? Dr. Fumiko Chino: Absolutely. Dr. Lin is one of my colleagues here at MD Anderson, so I know him very well, and he has been doing really phenomenal work over the last several years with looking at drug affordability and access. And what his analysis shows is that for patients, after the Inflation Reduction Act's cap on out-of-pocket expenses, is that it really did show that out-of-pocket expenses decreased. So what the Inflation Reduction Act did is that it eliminated the 5% co-insurance and placed this $2,000 cap on out-of-pocket expenses. And what that led to for these patients that were not able to have the low-income subsidy is that there were lower costs, and that there was a lower rate of drug abandonment, meaning that the prescription was not refilled. There was also a lower rate of unfilled prescriptions as well. And I think that it shows that health policy really can improve access to care. I think the flip side of the fact that the IRA, this policy, really did seem to help people is that what his research showed is that actually, even with the benefits of this cap, is that actually it is still really high in terms of the rate of people who are not able to fill their prescriptions or that completely abandon them over time. And that unfortunately, even with this change, that over half of people without the low-income subsidy were potentially not getting the full benefit of their medications because they were not able to afford them. And so I think it really kind of highlights that we still need to do more work about making drugs affordable. Dr. Monty Pal: Indeed, indeed. And I mean, in a setting like this, I mean, I think it is important to recognize that $2,000 is a lot, it is a big chunk of change, right, for a lot of families in the U.S. What do you think of the prospect of, like, decreasing that cap? Is that something that from a policy standpoint you would be supportive of? Dr. Fumiko Chino: Well, so something that is a real option for patients on Medicare is there is something called the Medicare Prescription Payment Plan, and what it allows you to do is actually prorate the $2,000 over the whole year. And so instead of having to pay $2,000 as soon as you fill your prescription, because you are going to have, if you have an expensive medication, it is essentially you have to pay the $2,000 in January, right? It allows you to prorate it, so essentially $170 a month, and that comes to you as like a regular bill. And I think that as rolled out as part of the IRA is a really lovely way of thinking about how do we make these payments more stable over time, so it is not a huge hit sort of at the beginning of the year. And I think that alone actually can make a difference in terms of trying to help make sure that people can actually get their medications. Dr. Monty Pal: That is an excellent tip. Excellent tip. We are going to shift gears entirely. We have been talking a lot about the dollars and cents of things and talk about an abstract from Sophia Smith and colleagues. So this is at your meeting. And this hinged on a program of sorts to deal with post-traumatic stress disorder. We do not often think about PTSD in the vernacular for oncology patients, but indeed, I mean, it is something that they must face, especially in the context of long-term survivorship. Can you talk a little bit about Dr. Smith's abstract? Dr. Fumiko Chino: Absolutely. I love this work from Dr. Smith, who is at Duke. She worked with Dr. Applebaum, who was my old colleague at Memorial Sloan Kettering. And this group of researchers really is trying to figure out how to best support people into survivorship so that they can actually thrive. And their patient population for this work was actually people who received stem cell transplant, and they focused on people who had PTSD symptoms. And what they were able to show through this SMART design, which is essentially this serial, multiple randomized trial, so everyone got randomized upfront to either usual care or this app, so this digital app that actually helped coach people through cancer distress. And then for the people who were non-responders, they were then additionally randomized to either the app plus coaching or a therapist versus the cognitive behavioral therapy or CBT. And what they were able to show is that, number one, anyone who had the app seemed like they did better than those who did not start the path with the app. But then the additional help of either the therapist or the coach or the CBT made additional benefit over time. And so, I think this shows a really nice stepped care, which is you can potentially have some right-sizing of treatments cost saving, if we sort of give everyone the app, which is, I think, overall pretty low cost. And that for the people who do not get the full benefit from the app, then you can think about these maybe more tailored approaches, the therapist, the coach, the CBT, but that some people actually just respond to the app. And I think it allows us to, again, right-size the care for our patients. And I think it is really innovative to think about how technology can help improve access to care in the setting of something like PTSD. Dr. Monty Pal: Brilliant summary. Brilliant summary. Gosh, it looks like such an exciting meeting this year. Congratulations on a terrific program for the ASCO Quality Care Symposium. I know you played a huge role in developing it, and thanks for sharing your insights on the ASCO Daily News Podcast. Dr. Fumiko Chino: No, I really appreciate you having me. ASCO Quality is my favorite meeting of the year. You know, it is really a phenomenal meeting, and I am so excited for next year in Boston in 2026. Dr. Monty Pal: Awesome.

Identifying Young BRCA Carriers With Breast Cancer: Early Detection Can Lead to Better Prognosis 10/02/2025

Identifying Young BRCA Carriers With Breast Cancer: Early Detection Can Lead to Better Prognosis Dr. Monty Pal and Dr. Matteo Lambertini discuss a compelling global study on the clinical behavior of breast cancer in young BRCA1 and BRCA2 carriers, the association of pre-diagnostic awareness of BRCA status with prognosis, and the importance of identifying healthy people who are at risk of carrying the BRCA1/2 pathogenic variants. TRANSCRIPT Dr. Monty Pal: Well, hello everyone, and welcome to the ASCO Daily News Podcast. I'm your host, Dr. Monty Pal. I'm a medical oncologist, professor, and vice chair of medical oncology at the City of Hope Comprehensive Cancer Center in Los Angeles. Now, when we think about genetic testing, whether for patients diagnosed with breast cancer or for other family members of them, it seems to be widely underutilized. Today, we're going to be discussing a recently published in the Journal of Clinical Oncology that reported on the clinical behavior of breast cancer and specifically young BRCA1 and BRCA2 carriers, and the association of pre-diagnostic awareness of BRCA status with prognosis. I thought this was just a fascinating piece, and I honestly couldn't wait to have this conversation. It's a really compelling paper that highlights the importance of identifying healthy people who are at risk of carrying the BRCA1/2 pathogenic variants, and really the need for genetic counseling and testing to inform people about early detection that could lead to a better prognosis. I'm really delighted to welcome the study's lead author, Dr. Matteo Lambertini. He really needs no introduction. He's very well known in the breast cancer world for his amazing contributions to fertility in the context of breast cancer, to pregnancy in the context of breast cancer, and genetic testing. He's an associate professor at the University of Genova, and a breast cancer medical oncologist at the San Martino Polyclinic Hospital in Genova, Italy. Dr. Lambertini, thank you so much for joining us today. Dr. Matteo Lambertini: Thank you very much, Dr. Pal. It's a great pleasure. Dr. Monty Pal: Oh, thanks. And just FYI, if you're listening in and you want to hear our disclosures, they're all listed at the transcript of this podcast. So, I poured through this paper [] yesterday, Dr. Lambertini, and first of all, congratulations on this study. This was a huge international multicenter effort, 4,752 patients. How did you pool all these patients with young breast cancer? Dr. Matteo Lambertini: Thanks a lot for the question. Yes, this was an effort made by several centers all over the world. The main idea behind the creation of this network that we have named as BRCA BCY Collaboration, was to get as many data as possible in a sort of niche patient population in the breast cancer field, meaning women diagnosed with breast cancer at the age of 40 years or younger, and all of them being BRCA carriers. We know that around, in the Western world, around 5% of breast cancer cases are being diagnosed under the age of 40 years, and among them around 10-15% are BRCA carriers. So, I would say it's a relatively rare patient population where we did not have a lot of evidence to support our choices in terms of counseling on treatment, prevention, and oncofertility as well. That was the idea behind the creation of this network that includes many centers. Dr. Monty Pal: Yeah. You know, what's so interesting about this is that you sort of draw this line between patients who have BRCA testing at the time of diagnosis and then BRCA testing earlier in their course and then leading to a diagnosis perhaps. And I think that's where really sort of the dichotomy in outcome sits. Can you maybe elaborate on this and tell us about timing of genetic testing in this study and what that meant ultimately in terms of prognosis? Dr. Matteo Lambertini: In this specific analysis from this large network, including almost 5,000 women with breast cancer diagnosed at the age of 40 years or younger and being a BRCA carrier, we looked specifically into the timing of genetic testing because this is a retrospective study and the criteria for inclusion are those that I have just mentioned, so diagnosis at a young age plus carrying germline BRCA pathogenic or likely pathogenic variant. In this analysis, we have looked into the time the patient has got the genetic testing and particular we focused on two populations: those that were diagnosed, knowing already to be a BRCA carrier, and those that got tested after being diagnosed with breast cancer. And the main findings from this analysis have been that knowing to be a BRCA carrier was associated with a lower stage at the time of diagnosis, meaning more T1 tumors, so a tumor less than 2 cm, more node-negative disease, and this translated into less aggressive treatment, so less often axillary dissection, less often use of chemotherapy and anthracycline-based chemotherapy. And even more importantly, we have seen a better overall survival for those patients that were diagnosed already knowing to be BRCA carriers as compared to those tested after breast cancer diagnosis. These results after adjusting for all the confounding, stage, treatment and so on, there was not significant anymore, meaning that it's not the timing of test per se that is probably leading to a better survival, but it is the fact that knowing to be a BRCA carrier would likely translate into having access to all the preventive measures that we have in this setting and this will translate into an overall survival benefit, so in terms of saving more lives in young BRCA carriers. Dr. Monty Pal: I think it's such an important point, and it's one that I think might sound implicit, right, but it needs to be proven, I think, through a study like this. You know, the fact that finding this early, identifying the mutation, doing enhanced screening, and so forth, is really going to lead to superior clinical outcomes. One of the things that I think many people puzzle over, including myself, is what to do? I personally occasionally will see BRCA altered patients in the context of prostate cancer. But that's a very different population of individuals, right? Typically older men. In young females with BRCA mutation, I guess there's a specific set of considerations around reproductive health. You'd already highlighted preventive strategies, but what sorts of things should we be talking about in the clinics once a patient's diagnosed and once perhaps their breast cancer diagnosis is established? Dr. Matteo Lambertini: Yes, exactly. Knowing to be a BRCA carrier has a lot of implications from prevention to treatment to survivorship issues including reproductive counseling. And this is important not only for the patient that has been diagnosed with breast cancer but also for all the family members that will get tested and maybe identify with this sort of genetic alteration before diagnosis of cancer. Why this is important is because we have access to very effective preventive measures, a few examples: MRI screening, which starts at a very young age and normally young women don't have an effective screening strategy outside the BRCA field. Also, primary preventive measures, for example, risk-reducing surgery. These women are known to have a high risk of breast cancer and high risk of ovarian cancer. So the guidelines are suggesting to undergo risk-reducing salpingo-oophorectomy at a young age, so 35 to 40 years in BRCA1 carrier, 40 to 45 years in BRCA2 carrier. And also risk-reducing mastectomy should be discussed because it is a very effective way to prevent the occurrence of breast cancer. And in some situations, including the setting that we are talking about, so young women with breast cancer, BRCA carrier, also risk-reducing mastectomy has shown to improve overall survival. On the other side, once diagnosed with breast cancer, nowadays knowing to be or not a BRCA carrier can make a difference in terms of treatment. We have PARP inhibitors in the early setting, in the adjuvant setting as well as in the metastatic setting. And in terms of survivorship implication, one of the critical aspects for young women is the oncofertility care which is even more complicated when we talk about BRCA carriers that are women candidates for gynecological surgery at a very young age. So this sort of counseling is even more complicated. Dr. Monty Pal: One of the other things, and this is subtle in your paper and I hope you don't mind me bringing it up, is the difference between BRCA1 and BRCA2. It really got me thinking about that because there are differences in phenotype and manifestation. Do you mind just expanding on that a little bit for the audience because I think that's a really important reminder that you brought up in the discussion? Dr. Matteo Lambertini: The difference between BRCA1 and BRCA2 carriers has been known that there are different phenotypes of breast cancer that are more often diagnosed in these two different populations. Normally BRCA1 carriers have a higher likelihood to develop a triple negative breast cancer as compared to BRCA2 carriers, more likely to develop a hormone receptor-positive HER2-negative disease. In this study, again, a specific population of young women with breast cancer, we have seen the same findings, mostly triple negative disease in BRCA1 carrier, mostly luminal-like disease in BRCA2 carrier. But what's novel or interesting from this study is to look also at the age at the time of diagnosis of this disease. And particularly in BRCA1 carriers, we should be sort of more careful about diagnosis of breast cancer and also other primary tumors including ovarian cancer because the risk of developing these malignancies is higher even at a younger age as compared to BRCA2 carriers. And this has implications also in the primary and secondary prevention that we were talking about earlier. Dr. Monty Pal: Oh, interesting. I guess the fundamental question then from your paper becomes, how do we get at the right patients for screening for BRCA1 and BRCA2? And I realize our audience here is largely oncologists who are going to be listening to this podcast, oncology providers, MDs, nurses, etc. But maybe speak for a moment to the general practitioner. Are there things that, for instance, a general practitioner should be looking for to say, “Wait a minute, this patient's high risk, we should consider BRCA1, BRCA2 testing or germline screening”? Dr. Matteo Lambertini: Yes, it's a very important question for the breast cancer community. After the updated ASCO guideline, the counseling is way easier because right now the age cutoff goes up to 65 years, meaning that all the patients diagnosed with breast cancer below the age of 65 years should be tested these days. And then above the age of 65, there are different criteria like triple-negative disease or family history. From a general practitioner standpoint, it's of course a bit more difficult, but knowing particularly the family history of the person that they have in front will be crucial to know if there are cases of breast cancer diagnosed at a young age, maybe triple-negative cases, knowing cases of ovarian cancer in first-degree relatives or pancreatic cancer in first-degree relatives, and of course cases of prostate cancer as well. So, I would say probably mostly the family side will be important from a general practitioner perspective. From an oncology one, the other point that I think is important to stress also based on the data that we have shown in this publication is that having a case of breast cancer known to carry a BRCA pathogenic or likely pathogenic variant. It means that all the people around this case should get tested and if found to be BRCA carrier and healthy carrier, these people should also undergo the primary and secondary prevention strategies because this is very critical also to improve their outcomes and try to avoid the developing of breast or ovarian cancer, but also in the case of diagnosis of this disease, a diagnosis at an earlier stage, as we have seen in this paper. Dr. Monty Pal: Brilliant. I'm going to diverge from our list of questions here and close by asking a question that I have at the top of my mind. You're very young. I know our podcast listeners can't see you, but you're very, very young. Dr. Matteo Lambertini: Thank you. Thank you for that. Not so young but yeah. Dr. Monty Pal: You have nearly 300 papers. Your H-index is 67. You've already made these seminal contributions, as I outlined it from the outset, regarding fertility, regarding use of GnRH analogs, regarding pregnancy and breast cancer. What are you studying now? What are you really excited about right now that you're doing that you think might potentially be practice changing? Give us a little teaser. Dr. Matteo Lambertini: Yeah. Thanks a lot, Dr. Pal. Receiving this compliment from you is fantastic. So, thanks a lot for that. From my side, in terms of my research, I've been interested in the field of breast cancer in young women since the start of my training. I've had very good mentors from Italy, from Europe, from the U.S. I'm still interested in this field, so I think we still have a lot to learn to try to improve the care of young women with breast cancer. For example, the oncofertility care, which is something I worked a lot over the past years. Now with all the new treatment options, there's a sort of new chapter of oncofertility counseling. So, what's the impact of immunotherapy? What's the impact of the new targeted agents? More on the genetic aspects, now we know that there's not only BRCA1 or BRCA2. There are a lot of other different genes that may increase the risk of breast cancer and other malignancies. And also for these genes, we really don't have a lot of evidence to counsel women on prognosis, treatment, prevention strategy. So we need to learn way more for this special patient population that are quite rare, and so we really need a multicenter academic effort to try to give some evidence in this field. Dr. Monty Pal: Yeah. It's tough because these are rare circumstances, but, you know, I think that you've done really well to sort of define some collective experiences that I think really define therapy. I mean, I just remember when I was in training 25 years ago, just reading through textbooks where all the experience around breast cancer and pregnancy was really just very sort of anecdotal almost, you know? And so it's great to see that the state of the science has moved forward. Well, gosh, I really enjoyed our conversation today. I think your study really reminds us how powerful genetic information is in terms of improving outcomes. And, you know, hopefully this will lead some individuals to perhaps test more broadly in appropriate settings. So, thank you so much, Matteo, for joining us today with your fantastic insights on the ASCO Daily News Podcast. Dr. Matteo Lambertini: Thank you very much, Dr. Pal. It’s a real pleasure. Dr. Monty Pal: And thanks to our listeners too. You'll find a link to Dr. Lambertini's study in the transcript of this episode.

Cancer and Aging: Researching the Path to Longer, More Vibrant Lives 09/18/2025

Cancer and Aging: Researching the Path to Longer, More Vibrant Lives Dr. Monty Pal and Dr. Mina Sedrak discuss the science behind cancer treatment-induced accelerated aging and the development of drug therapies and technologies aimed at helping older patients and cancer survivors. TRANSCRIPT Transcript: Cancer and Aging: Researching the Path to Longer, More Vibrant Lives Dr. Monty Pal: Hello, and welcome to the ASCO Daily News Podcast. I am Dr. Monty Pal. I am a medical oncologist and professor and vice chair of medical oncology here at the City of Hope Comprehensive Cancer Center. I am also host of this podcast. Today, we are going to be talking to somebody that I consider to be my little brother, if you will, in oncology, Mina Sedrak. Mina is an expert in the area of cancer and aging, which really includes the development of drug therapies and technologies that help enable older adults and survivors to live longer, healthier, and more vibrant lives. I am really excited to chat with him. He is an expert not just in cancer and aging but also breast cancer. He was my former colleague here at City of Hope before he moved over to the UCLA Jonsson Comprehensive Cancer Center, where he is an associate professor and director there of the Cancer and Aging Program. Dr. Sedrak’s research involves mechanisms behind cancer treatment-induced accelerated aging and really aims to take this science into more of a therapeutic direction, which I am super, super excited about. Mina, thanks so much for joining us today, and just FYI for our listeners, we have all of our disclosures in the transcript of this episode. Dr. Mina Sedrak: Thank you, Monty. Thank you, Dr. Pal, for having me. I am really excited to be here. Dr. Monty Pal: I feel like we have to go on a first-name basis here with how well we know each other. So Mina, you and I together have witnessed this evolution in cancer and aging. I mean, both of us worked together here with just a legendary figure in the field of geriatric oncology, I will call it, Dr. Arti Hurria, mentor to me, mentor to you, mentor to so many. Can you give us a sense of where cancer and aging has gone since the time that you and I started here together at City of Hope? Dr. Mina Sedrak: Dr. Hurria and her collaborators, Dr. [Willliam] Dale and Dr. [Supriya] Mohile, they were like huge pioneers in the field. They were one of the very first people to highlight the importance of looking at older adults beyond just their chronological age and their comorbidities and moving us beyond just seeing patients and making decisions using what we call the eyeball test. "Oh, this person looks fit or not fit, frail or robust," to really using objective measures to assess our patient's health status and incorporate that assessment into our evaluation of the treatment, prognostication, and discussions with our patients throughout the cancer continuum. And so that is what geriatric oncology has and continues to be, and it is a huge, important part. And their work has laid the foundation to show that when we look at our patients beyond just their chronological age and we look at their functional age, and we do these objective assessments, we can gain much more deeper information to tailor the treatment for our patient that is sitting in front of us, rather than do a prescriptive treatment or over- or undertreatment in that population. So that is sort of where the field is growing, and a lot of the work now is, how do we implement that? How do we put that into clinical practice? Dr. Monty Pal: Well, let me kind of spearhead that discussion, right? I have these moments when I go to the ASCO Annual Meeting – I remember this happened to me a while ago when Dr. Jennifer Temel presented that terrific work around early palliative care interventions, right? Or it even happened to me this year, right, when Dr. Christopher Booth presented the trial around exercise and colon cancer. You know, these amazing, I am going to say simple, they are not simple, but they are simple interventions relative to, you know, some of the complex drugs and mechanisms that we are using nowadays that really help outcomes for our cancer patients. The big question becomes, how do you implement, right? But my understanding is that there are easy ways for us to take tools in cancer and aging and sort of plug them into our daily practice. Am I right about that? Dr. Mina Sedrak: Yes, and that is something that they are – the , which was founded by Dr. Hurria and now is co-led by Dr. Dale, Dr. Mohile, and Dr. [Heidi] Klepin, they have been incredible at really trying to develop practical tools, like the , which is now endorsed by the ASCO and other NCCN guidelines. And so, there are tools that are becoming more and more practical to help incorporate that into clinic. Now, what might be practical in a resource-intensive setting may not be practical in some of the limited resources, whether it is rural and/or other countries where the resources may be more limited. So that is why Cristiane Bergerot, Enrique Soto, and others have been really working hard. There was actually a really beautiful paper that was just published in the Journal of Global Oncology, where they have shown that there are guidelines [] about how to implement these tests, these tools, these assessments in clinical practice, even in different resource settings. So I think we are going to get to the future where this is much more – it is definitely important, but it is much more easily ‘incorporatable’ into our practice. Dr. Monty Pal: Yeah, you know how close I am to Cris, and I was so proud when I saw that paper come out. That was really exciting. You know, I skimmed it. I have to tell you, I did not get into the weeds, but it was apparent to me that, you know, some of these geriatric oncology tools are things that, you know, I could probably plug and play into my practice where I am double- and triple-booked over, you know, most slots, right? I mean, I could still probably afford a little bit of time or maybe have, like, a nurse or an extender kind of help participate in the evaluation process. I thought that was, yeah, really, really interesting. Dr. Mina Sedrak: I will just say that at UCLA, we are working with Dr. Arash Naeim, who is a geriatric oncologist, and he has developed an AI platform where the assessments can be done by an AI computer. So it is like talking to your ChatGPT. They can talk to you, and for a few minutes, they will ask you the questions. So you do not even have to fill it out on a piece of paper. You could give the patient a little iPad, put them in a private room while they are waiting for their doctor, and get the results, and it is right there for you. And so, we have been trying to think about how can technology help with the completion of the assessment, at least doing that? And I think it is actually, it has been very cool. We did a pilot study. He is writing that up, and we are going to continue to do some of this exciting work. How do we think about AI in the context of this? And, you know, older adults, they are not like what they used to be. A lot of older adults are very familiar with and comfortable with phones and computers and iPads, much more so today than they were even at the time when Dr. Hurria was alive. Dr. Monty Pal: That is so interesting. You mentioned this, the AI approach is something I have been thinking about in this context because what if, for instance, you know, we have got video monitors all over our hospital, right? What if you are actually just taking a look at that patient as they make their way towards your clinic? Capture that video, use an AI algorithm to say, "Hey, you know, the timed get-up-and-go test in this patient is not particularly good based on what I am seeing here," right? There are so many ways that you could, you know, stir the pot and come up with creative ways to get these tests done. Dr. Mina Sedrak: That's right. And Arash is looking at also sensors. So he has some studies where he is putting sensors inside people's homes, where they would put them, like, on top of an Alexa app or the equivalent. A lot of people have these apps, and basically, they can sense how you are moving around and what you are doing, just movement-wise. And then they can collect that information to gain information about your life beyond just what we are seeing in the 20-minute visit in the clinic. Even when I do a walk test where I get gait speed or physical performance, short physical performance battery, the chair sit-up, those are oftentimes a single, cross-sectional, static measure. But what about the dynamic ability of capturing what has been happening for the last 7 days? What has been happening for the last 25 days between the visits, between the cycles of chemotherapy? And could that inform how I make decisions when I see patients and who do I need to target and identify? And so, we are very excited because really at UCLA, Arash is leading the technology efforts and thinking about implementation of these important measures and these important tools but leveraging new technology. And we do not want to be behind; we want to be ahead of the game. Dr. Monty Pal: I love that idea because there is a Hawthorne effect, isn't there, where you observe a process, and it naturally gets better. I mean, when you ask that patient to get up in the clinic and move, they are probably functioning to the best of their abilities, but we could probably learn a lot from just watching how fast that patient picks up a remote control at home. Some simple movement like that that is volitional would probably help out a ton. And I got to tell you, it is so funny when you mention Arash Naeim’s name. I distinctly remember him serving as an attending on the wards when he was brand new at UCLA on faculty when I was a resident there. And his dad is a legendary hematopathologist, right? Dr. Mina Sedrak: I did not know that. Dr. Monty Pal: Yeah, yeah. Faramarz Naeim wrote the book on a lot of heme-path malignancies. Incredible guy. Very, very storied hematopathologist at UCLA. I could probably go on this topic forever, but in the interest of time, I am going to shift to something that again, I could probably talk about forever, which is this area of senescence that you are involved in. You know, you had mentioned this to me, I am going to say during your outro from City of Hope and towards your transition to UCLA, it is such an exciting area. I mean, understanding the actual biologic process of aging and using those underpinnings to really sort of tailor therapy. So tell us where the state of the science is there with this body of work that you are doing. Dr. Mina Sedrak: As I said before, we have tools now to assess patients and to then do something about the deficits. So if a patient is falling, what we do is we refer them to physical therapy where they can do fall precautions and strength training to give them the information. But all of these supportive care interventions are very important. They are great. But they oftentimes are not targeting the root cause of why they are happening. And so that is really where I have been very interested in, how can we understand why is it that something like chemotherapy or immunotherapy is causing a decline in cognitive function or a decline in physical function? And so that has really led us to think about geriatric oncology rather than a discipline of older adults, but to think about aging as a physiologic process. We are all aging. As every day goes by, we are aging. And what that means is that our bodies are accumulating damage, the cells are being exposed to various stressors, and the repair mechanisms are declining. And as we get older, it is really more damage and less repair mechanism at the cellular molecular level. And it turns out that these processes of how our cells repair and respond to damage are fundamental processes of biological aging. And there has been a large amount of preclinical and now really exciting clinical work to show that there are hallmarks that could be used to assess the rate of which we age by looking at these processes. And that includes things like epigenetics, telomeres, inflammation, and something called ‘cellular senescence.’ And we have been interested in my lab in senescence because it is a unique process that has an important role in aging, but it also has a really important role in cancer. Senescence is a cell state. Cells, when they are stressed, they respond to entering this state of senescence. The stress could come from anything. It could come from an oncogene activation. It could come from a reactive oxygen species. It could come from a direct damage to the cell. But it is a cell state, just like apoptosis, necrosis. Senescence is a state in which the cell, in response to that stressor, undergoes an arrest from the G to the S phase. And that arrest is oftentimes associated with a resistance to apoptosis. So then the cell does not die, but it is alive, and it remains metabolically active. And in fact, downstream pathways of these cell cycle inhibition of this G-to-S phase lead to the increase of these transcription factors in the chromatin and lead to the development of these pro-inflammatory factors. So these cells, which can occur in various tissues in the body, can continue to live despite having developed these changes, and then they secrete these proinflammatory molecules like cytokines, chemokines, metalloproteinases, all of these, which are called the senescence-associated secretory phenotype, or SASP. And as we age, we accumulate more and more of these cells, and our bodies are no longer able – our immune system, like macrophages and T cells – are no longer able to remove them effectively. And as we accumulate them in various organs, these organs release a lot of inflammatory cytokines, and the chronic inflammation in that tissue leads to the tissue being damaged, and it does not work as well, and then it starts to decline in function. And that is believed to be how senescence plays a role in aging. It is the accumulation of senescent cells that occurs with increased damage and then the repair mechanism of clearing these cells effectively, which then leads to build up of inflammation and chronic inflammation leads up to damage in multiple tissues. Dr. Monty Pal: This concept to me is fascinating. And I guess the big question is – senescence is bad, right – is it not reasonable to think that this body of research, I mean, if you are able to sort of have a meaningful impact on senescence, it could have implications well beyond oncology. Is that fair? You really could extend lifespan all around. Is that reasonable to think, all-cause mortality? Dr. Mina Sedrak: One hundred percent. And that is what they have been shown in animal models. And the reason senescence is exciting is because it turns out that you can target these cells and you can induce apoptosis of these cells, but it requires active targeting of various pathways, but it can occur. And when it does, and it is done either genetically or pharmacologically in mice, we see that the mice can reverse damage. So if you take an old mouse and you genetically engineer it to remove senescent cells, that mouse will go from being frail to fit. And if you take a young mouse and you induce senescent cells at a high rate and you accumulate them in that mouse, that mouse, even though it is young, will become frail. So that has really led to this exciting opportunity of, can we translate this finding that we are seeing in animals and in in vivo cells, cell cultures, into humans? And could that have a benefit beyond just one disease? Could it have a benefit in multiple diseases? And not just really longevity, which I think it would be great, but what people are really looking for is, how do we live healthy as we get older? How do we move the curve so that people are not developing chronic diseases in their 60s, but they are developing them in their 80s towards shortening the period of their life with disability rather than what we have currently, which is people are living to 70s, the average life expectancy is in the mid-70s, but they are spending 10 or 11 years in disability of that life. And so, how could we reduce that time frame? Dr. Monty Pal: This is brilliant, Mina. And for our audience, this compelling dialogue that we have had here thankfully is translating to funding for Mina's work. He just scored in the second percentile for his NIH R01 based on this topic. We are so, so proud of you. I mean, it is just remarkable work. It is not easy in the current climate to get funding, and a second percentile score is just absolutely wonderful. You know, Mina, I could probably go on with you for a couple more hours here talking about your work in cancer and aging. I think I am going to have to have you back on the podcast here. But a million thanks for sharing your thoughts here today on the ASCO Daily News Podcast. And thanks to our listeners too.

Promising New Therapies in Non-Muscle Invasive Bladder Cancer 09/04/2025

Promising New Therapies in Non-Muscle Invasive Bladder Cancer Dr. Sumanta (Monty) Pal and Dr. Petros Grivas discuss innovative new intravesical therapies and other recent advances in the treatment of non-muscle invasive bladder cancer. TRANSCRIPT Dr. Sumanta (Monty) Pal: Hello and welcome. I'm Dr. Monty Pal here at the ASCO Daily News Podcast. I'm a medical oncologist and professor and vice chair of academic affairs at the City of Hope Comprehensive Cancer Center in Los Angeles. And I'm really delighted to be your new host here. Today's episode is going to really sort of focus on an area near and dear to my heart, something I actually see in the clinics, and that's bladder cancer. We're specifically going to be discussing non-muscle invasive bladder cancer, which actually comprises about 75% of new cases. Now, in recent years, there's been a huge shift towards personalized bladder-preserving strategies, including innovative therapies and new agents that really are reducing reliance on more primitive techniques like radical cystectomy and radiation therapy. And I'm really excited about this new trend. And really at the forefront of this is one of my dear friends and colleagues, Dr. Petros Grivas. He's a professor in the Department of Medicine and Division of Hematology Oncology at the University of Washington. It's going to take a while to get through all these titles. He's taken on a bunch of new roles. He is medical director of the International Program, medical director of the Local and Regional Outreach Program, and also professor in the Clinical Research Division at the Fred Hutch Cancer Center. Petros, welcome to the program. Dr. Petros Grivas: Thank you so much, Monty. It's exciting for me to be here. Dr. Sumanta (Monty) Pal: Just FYI for our audience, our disclosures are available in the transcript of this episode. We're going to get right into it, Petros. Non-muscle invasive bladder cancer, this is a really, really challenging space. We see a lot of recurrence and progression of the disease over time, about 50% to 70% of patients do have some recurrence after initial treatment, and about 30% are ultimately going to progress on to muscle-invasive or metastatic disease. Now, I will say that when you and I were in training, non-muscle invasive bladder cancer was something that was almost relegated to the domain of the urologist, right? They would use treatments such as BCG (Bacillus Calmette-Guérin) in a serial fashion. It was rare, I think, for you and I to really enter into this clinical space, but that's all changing, isn't it? I mean, can you maybe tell us about some of the new therapies, two or three that you're really excited about in this space? Dr. Petros Grivas: Monty, you're correct. Traditionally and conventionally, our dear friends and colleagues in urology have been managing patients with non-muscle invasive bladder cancer. The previous term was superficial bladder cancer. Now, it has changed, to your point, to non-muscle invasive bladder cancer. And this has to do with the staging of this entity. These tumors in superficial layers of bladder cancer, not invading the muscularis propria, the muscle layer, which makes the bladder contract for urine to be expelled. As you said, these patients have been treated traditionally with intravesical BCG, one of the oldest forms of immunotherapy that was developed back in the 1970s, and this is a big milestone of immunotherapy development. However, over the years, in the last 50 years, there were not many options for patients in whom the cancers had progression or recurrence, came back after this intravesical BCG. Many of those patients were undergoing, and many of them still may be undergoing, what we call radical cystectomy, meaning removal of the bladder and the lymph nodes around the bladder. The development of newer agents over the last several years has given the patients the option of having other intravesical therapies, intravesical meaning the delivery of drugs, medications inside the bladder, aiming to preserve the bladder, keep the bladder in place. And there are many examples of those agents. Just to give you some examples, intravesical chemotherapy, chemotherapy drugs that you and me may be giving intravenously, some of them can be given inside the bladder, intravesical installation. One example of that is a combination of gemcitabine and docetaxel. These drugs are given in sequence one after the other inside the bladder, and they have seen significant efficacy, good results, again, helping patients keeping the bladder when they can for patients with what we call BCG unresponsive non-muscle invasive bladder cancer. And again, there's criteria that the International Bladder Cancer Group and the FDA developed, how to define when BCG fails, when we have BCG unresponsive non-muscle invasive bladder cancer. Dr. Sumanta (Monty) Pal: And we're actually going to get into some of the FDA requirements and development pathways and so forth. What I'm really interested in hearing, and I'm sure our audience is too, are maybe some of the new intravesical treatments that are coming around. I do think it's exciting that the gemcitabine and docetaxel go into the bladder indeed, but what are some of the top new therapies? Pick two or three that you're excited about that people should be looking out for in this intravesical space. Dr. Petros Grivas: For sure, for sure. In terms of the new up-and-coming therapies, there are a couple that come to mind. One of them is called TAR-200, T-A-R 200. This agent is actually a very interesting system. It's an intravesical delivery of a chemotherapy called gemcitabine, the one that I just mentioned a few minutes ago, that is actually being delivered through what we call a pretzel, which is like a rounded [pretzel-shaped] structure working like an osmotic pump, and that is being delivered inside the bladder intravesically by urologists. And this drug is releasing, through the osmotic release mechanism, this chemotherapeutic drug, gemcitabine, inside the bladder. And this can be replaced once every 3 weeks in the beginning. And the data so far from early-phase trials are really, really promising, showing that this agent may be potentially regulatory approved down the road. So TAR-200 is something to keep in mind. And similarly, in the same context, there is a different drug that also uses the same mechanism, and this osmotic release, this pretzel, it’s just encoded with a different agent. The different agent is an FGFR inhibitor, a target therapy called erdafitinib, a drug that you and me may give in patients with metastatic urothelial carcinoma if they have an FGFR3 mutation or fusion. And that drug is called TAR-210. Dr. Sumanta (Monty) Pal: And can I ask you, in that setting, do you have to have an FGFR3 mutation to receive it? Or what is the context there? Dr. Petros Grivas: So for TAR-210, TAR-2-1-0, usually there is a checking to see if there is an FGFR3 mutation or fusion. And the big question, Monty, is do we have adequate tissue, right? From a limited tissue on what we call the TURBT, right, that urologists do. And now there is a lot of development in technology, for example, urine circulating tumor DNA to try to detect these mutations in the urine to see whether the patient may be eligible for this TAR-210. Both of those agents are not FDA approved, but there are significant promising clinical trials. Dr. Sumanta (Monty) Pal: So now let's go to a rapid-fire round. Give us two more agents that you're excited about in this intravesical space. What do you think? Dr. Petros Grivas: There is another one called cretostimogene. It's a long name. Dr. Sumanta (Monty) Pal: They really make these names very easy for us, don't they? Dr. Petros Grivas: They are not Greek names, Monty, I can tell you, you know. Even my Greek language is having trouble pronouncing them. The cretostimogene, it's actually almost what we call a growth factor, a GM-CSF. The actual name of this agent is CG0070. This is a replicating mechanism where GM-CSF is replicating in cells. And this agent has shown significant results again, like the TAR-200, in BCG unresponsive non-muscle invasive bladder cancer. I would say very quickly, two agents that actually were recently approved and they're already available in clinical practice, is nadofaragene firadenovec, another long name. That's a non-replicating vector that has the gene of interferon alfa-2b that stimulates the immune system in the bladder. It's given once every 3 months. And the last one that was, as I mentioned, already FDA approved, it's an interleukin-15 superagonist. It's another long name, which is hard to pronounce, but I will give it a try. It's a drug that was recently actually approved also in the UK. The previous name was N-803. It's given together with BCG as a combination for BCG unresponsive non-muscle invasive bladder cancer. Dr. Sumanta (Monty) Pal: This is a huge dilemma, I think, right? Because if you're a practicing, I'm going to say urologist for the moment, I guess the challenge is how do you decide between an IL-15 superagonist? How do you decide between a pretzel-eluting agent? How do you decide between that and maybe something that's ostensibly, I'm going to guess, cheaper, like gemcitabine and docetaxel? What's sort of the current thinking amongst urologists? Dr. Petros Grivas: Multiple factors play into our account when the decision is being made. I discuss with urologists all the time. It's not an easy decision because we do not have head-to-head comparisons between those agents. As you mentioned, intravesical chemotherapy with gemcitabine and docetaxel has been used over the years and this is the lowest cost, I would say, the cheapest option with good efficacy results. Obviously, the nadofaragene firadenovec every 3 months and the interleukin-15 superagonist, N-803, plus BCG have also been approved. The question is availability of those agents, are they available? Are they reimbursed? Cost of those agents can come into play. Frequency of administration, you know, once every 3 months versus more frequent. And of course, the individual efficacy and toxicity data, preference of the patients; sometimes the provider, the urologist, may have something that they may be more familiar with. But we lack this head-to-head comparison. Of course, I want to make sure I mention that radical cystectomy may still be the option for appropriate patients. So that complicates also the decision making and has to be individualized, customized, and personalized, taking into account all those factors. And there is not one size fitting all. Dr. Sumanta (Monty) Pal: So I think we discussed five intravesical therapies. As you point out, and you know, I'm going to get some calls about this: I think I referred to radical cystectomy as being a more primitive procedure. Not true at all. I think it's something that still is, you know, a mainstay of management in this disease space. But I guess it gets even more complicated, am I right, Petros? Because now we have systemic therapies that we can actually apply in this non-muscle invasive setting for at this point, refractory disease. Can you maybe just give us a quick two-minute primer on that? Dr. Petros Grivas: Absolutely, and systemic therapies now come into play, as you said. And a classical example of that, Monty, came from the trial that we published about 6 years ago. This is intravenous pembrolizumab, given intravascularly, intravenously, as opposed to the previously discussed intravesical administration of agents. Pembrolizumab was tested in that KEYNOTE-057 trial and showed efficacy about, I would say, one out of five patients, about 20%, had a complete response of the tumor in the bladder in a year after starting the treatment. Again, it's hard to compare across different agents, but obviously when we give something intravenously, there is a risk of toxicity, side effects systemically, what we call immune-related adverse events. And this can also play in the decision making, right? When you have intravesical agents versus intravascular agents, there is different toxicity profiles in terms of systemic toxicity. But intravenous pembrolizumab has been an option, FDA approved, since, if I remember, it was early 2020 when this became FDA approved. There are other agents being tested in this disease, but like atezolizumab through the that Dr. Black and Dr. Singh led, but atezolizumab is not FDA approved for this indication. Again, this is for BCG unresponsive, high-risk, non-muscle invasive bladder cancer. Dr. Sumanta (Monty) Pal: So maybe teach us how it works, for instance, at an expert center like the Fred Hutch. When you see a patient with non-muscle invasive bladder cancer, there's obviously the option of surgery, there's the intravesical therapies, which I imagine the urology team is still really at the helm of. But then, I guess there has to be consideration of all options. So you've got to bring up systemic therapy with agents like pembrolizumab. In that context, are you involved that early on in the conversation? Dr. Petros Grivas: That's a great discussion, Monty. . We have the concept of multidisciplinary bladder cancer clinic here at Fred Hutch and University of Washington. This happens every Tuesday morning, and we're very excited because it's a one-stop shop for the patients. We have the urologist, a medical oncologist, radiation oncologist, and experts from radiology and pathology, and we all review cases specifically with muscle-invasive bladder cancer. But every now and then, we see patients with BCG unresponsive non-muscle invasive bladder cancer. And this is where we discuss and we talk to the patient about pros and cons of all those options. And that's a classic example where medical oncologists may start to see those patients and offer their input and expertise. In addition to that, sometimes we have clinical trials, we may see these patients because there are systemic agents that may be administered in this setting. We have the program that includes also a systemically administered checkpoint inhibitor. So that's another example where we see patients either in the context of multi-clinic or in individual solo clinics to counsel the patients about the pros and cons of the systemically administered agents in the context of clinical trials. Usually checkpoint inhibitors are the class of agents that are being tested in this particular scenario. Dr. Sumanta (Monty) Pal: I can see a scenario where it's really going to require this sort of deep dive, much in the way that we do for prostate cancer, for instance, where the medical oncologist is involved very early on and planning out any sort of systemic therapy component of treatment or at the very least, at least spelling out those options. I think it's going to be really interesting to see what this space looks like 5 or 10 years down the road. In closing, I wanted to go through something that I think is so different in this space, at least for the time being, and that is the paradigm for FDA approval. When you and I have our fellows in the clinics, we always say, “Look, you know, the paradigm in this disease and that disease and the other disease needs to be phase 3 randomized trials, right? Big thousand patient experiences where you're testing clinical endpoints.” That's tough in non-muscle invasive bladder cancer, right? Because thankfully, outcomes can actually be quite good, you know, in this setting, right? It's tough to actually estimate overall survival in some of these early-stage populations. Tell me what the current regulatory bar is, and this is a tough thing to do in 2 minutes or less but tell me where you see it headed. Dr. Petros Grivas: You alluded to that before, Monty, when I was giving the background and we talked about the regulatory approval. And I have to very quickly go back in time about 10 years ago because it's important for context that can help us in other disease types too. We had workshops with the FDA and the NCI with the help of the International Bladder Cancer Group and other colleagues. And we try to define a framework, what endpoints are meaningful for those patients in this disease. It was a multidisciplinary, multiple stakeholders meeting, where we tried to define what is important for patients. What are the available agents? What are the trial designs we can accept? And what are the meaningful endpoints that the regulatory agencies can accept for regulatory approval? And that was critical in that mission because it allowed us to design clinical trials, for example, single-arm trials in a disease where there was no standard of care. There was intravesical valrubicin and chemotherapy anthracycline that was approved for many years, but was not practically used in clinical practice, despite being approved, the valrubicin. And because of that, the FDA allowed these single-arm trials to happen. And obviously the endpoint was also discussed in that meeting. For example, for carcinoma in situ, complete response, clinical complete response, because the bladder remains intact in many patients, clinical complete response was a meaningful primary endpoint, also duration of response is also very important. So what is the durable clinical complete response in 1 year or 18 months is relevant. And when you have papillary tumors like Ta or T1 with CIS, for papillary tumors, event-free survival becomes one of the key endpoints and you look at it over time, for example, at 12 or 18 months, what is the event-free survival? So clinical complete response, duration of response, event-free survival, depending on the CIS presence or papillary tumors, I think these are endpoints that have allowed us to design those trials, get those agents approved. Now, Dr. Sumanta (Monty) Pal: Well, it's awesome to have you here on the program so we can get some early looks into some of these conversations. I mean, clearly, you're at the table at a lot of these discussions, Petros. So I want to thank you for sharing your insights with us today. This was just tremendous. Dr. Petros Grivas: Thank you, Monty. You know, patients in the center, I just came back from the Bladder Cancer Advocacy Network meeting in Washington, D.C., and we discussed all those questions, the topics you very eloquently mentioned and asked me today, and patients gave us great feedback and patients guide us in that effort. Thank you so, so much for having me and congratulations for the amazing podcast you're doing. Dr. Sumanta (Monty) Pal: Oh, cheers, Petros, thanks so much.

The Gut Microbiome and Immunotherapy: Researching the Connection 08/21/2025

The Gut Microbiome and Immunotherapy: Researching the Connection Dr. Sumanta (Monty) Pal and Dr. Arielle Elkrief discuss the clinical relevance of the gut microbiome in cancer immunotherapy and the importance of antibiotic stewardship, as well as interventions currently being explored to treat gut dysbiosis and optimize immunotherapy response. TRANSCRIPT Dr. Sumanta (Monty) Pal: Hi everyone, I'm Dr. Monty Pal, welcoming you to the ASCO Daily News Podcast. I'm a medical oncologist. I'm a professor and vice chair of academic affairs at the City of Hope Comprehensive Cancer Center in Los Angeles. Today we're here to discuss one of my favorite topics, which is the gut microbiome. It's almost hard to avoid the gut microbiome nowadays if you look at medical literature within oncology. It's an emerging phenomenon, but there are a couple of individuals that I would really define as pioneers in the field. And one of them is actually with me today, Dr. Arielle Elkrief, to discuss the clinical relevance of the gut microbiome, particularly amongst patients receiving immunotherapy, although I imagine our conversation today will take many twists and turns. Arielle is an assistant professor and clinician scientist in the Department of Oncology at the University of Montreal, and she is co-director of the CHUM Microbiome Center there. FYI for the listeners, we have our full disclosures in the transcript of this episode. Arielle, thank you so much for joining us today. Dr. Arielle Elkrief: Thanks so much, Monty. This is going to be amazing. Dr. Sumanta (Monty) Pal: Well, I have to tell you what sort of inspired me to bring you on as a guest. It was one of many things, but it was this really terrific that you wrote. Now, I have to tell you, I've read all the articles sort of cover to cover in the book, and they're always a wonderful primer, so if our audience is studying for board research or something of that sort, it's a terrific resource to go through. I have to tell you, this piece on the gut microbiome that you wrote is nothing short of a masterpiece. If you read this cover to cover, it's actually going to give you, I think, a sense of the current state and future state of the field. I wanted to start by just sort of beginning with sort of the origin story for a lot of this, which is this association between the gut microbiome and immunotherapy response. This takes us back several years to this pivotal series of papers in Science. Maybe you could walk our audience through that. Dr. Arielle Elkrief: Absolutely. Well, thank you so much for your kind words about the ASCO [Educational] Book. It was a team effort with a lot of key opinion leaders in the field, so I'm really glad to learn that you've liked it. Moving backwards in terms of how we came to understand that the gut microbiome is essential to priming a response to cancer immunotherapy actually goes back to 2015 and seminal papers that looked at what happens when we take mice that are germ-free mice that have never been exposed to a microbiome. These are mice that are born by cesarean section and essentially live in a bubble. And when we give those mice tumors and treat them, in the first papers with anti-CTLA-4 treatment, we realized that these antibodies don't work at all. And that was the first observation that the presence of a gut microbiome was essential to mounting an anti-cancer immune response. When we supplemented those same mice with beneficial bacteria or feces from responder patients, we were able to restore the response to immunotherapy. And so those were really the first preclinical observations that made us understand the critical role of the microbiome in immunotherapy response. Moving a little bit in the future, we examined the fecal microbiome composition using shotgun metagenomic sequencing in different cohorts of patients with solid tumors, namely lung cancers, kidney cancers, and also skin tumors like melanoma, and found that patients who responded to immunotherapy had a distinct microbiome that was characterized by beneficial bacteria compared to patients who experienced resistance to immunotherapy that had a dysbiotic or diseased microbiome. Dr. Sumanta (Monty) Pal: So, you know, it's interesting, these techniques that we're using to sequence the gut, they're a little bit different. So I wonder if you can give the audience a quick primer on these techniques that you're so well versed in, shotgun metagenomic sequencing, 16S rRNA sequencing. If you had to describe this in 30 seconds, which is a tall task, how would you do that? Dr. Arielle Elkrief: That's a tall task. Much of what we know about the microbiome initially came from a technique called 16S rRNA sequencing. This is a technique that amplifies the 16S region and basically tells you at the genus level what's going on at the level of bacterial composition. This technique is fast, relatively cheap, and can be performed on a laptop computer, which is excellent. The problem is that it's prone to a lot of technical variations. Different primers might give you different results, and you're really limited at the genus resolution. You can't get a good resolution in terms of species, and we're learning that different species from the same genus might have different physiological properties, and the same thing goes at the strain level. So when we really zone in and look at inter-species changes, we're seeing that these actually have specific functions in the host. So that brings us to metagenomic sequencing, which is a whole genome sequencing, next-generation sequencing based method that looks at the whole composition and gives you information not only on bacteria, but you might also get fungal and viral properties. You can zoom in on the strain level. You can also get functional output, so we can examine what the metabolic properties of specific species or strains might look like. The negative aspects of shotgun metagenomic sequencing is that it takes a lot of computational power in order to analyze the results and it might take a little bit longer. And certainly, within the clinical setting, not something that's feasible yet. And that brings us to more novel point-of-care biomarker tools that we've collaborated in developing along with Dr. Laurence Zitvogel and Dr. Lisa Derosa at Gustave Roussy, that learning from the shotgun metagenomics results designed a probe using quantitative PCR which looks for this specific bacteria we know to be important and developed a ratio of harmful bacteria to beneficial bacteria. This is called the , and it actually is able to predict quite nicely the response to immunotherapy using a stool sample and a really good turnaround time of almost 72 hours. Dr. Sumanta (Monty) Pal: That was a perfect overview and a lot of information in a short amount of time. It also makes you take out your high school biology textbooks, doesn't it, to understand that the bacterial ribosome, right, is a different size and shape, and that's what we're sequencing here. But these techniques I think are incredibly important, and I'm glad you actually discussed this, this RT-PCR based strategy of calculating the TOPOSCORE. It lends itself to this phenomenon of dysbiosis, and I think for our audience, that's going to be an important term to understand as time goes on. There's the normal healthy gut and then there's this phenomenon of dysbiosis, which is, I guess, simply put, an unhealthy gut. But tell us about, you know, how often you see dysbiosis in a cancer patient, maybe versus a normal healthy adult. Dr. Arielle Elkrief: So, I think we can split up your question into two parts. One is we know from cohort studies and population level-based studies that the microbiome of patients with cancer is distinct from healthy patients or healthy people. And we know that because of the global composition. We also think that there are diversity metrics that lend themselves to being described as dysbiotic. But we do know that the microbiome of people with cancer is distinct from healthy volunteers. That's the first point. In terms of how frequently dysbiosis occurs in patients with cancer, it's not very well defined. We know that even among healthy people, there is a certain level of dysbiosis. Laurence in her talk mentioned that to be about 10% to 20%. And the other fascinating component is that when we're thinking about dysbiosis and the cancer associated microbiome, in terms of the species that are enriched, it's quite striking that a lot of these dysbiotic or negative bacteria are also found to be enriched in patients with metabolic disease, like cardiovascular disease, for example. And so it's unclear if dysbiosis is the cause or consequence, but there definitely seems to be a general pattern of disease when looking at the microbiome compared to healthy people. Dr. Sumanta (Monty) Pal: That's interesting. So, I'll tell you, my second favorite portion of your article, and I'll tell you my favorite portion as well in the context of this podcast, but my second favorite part was the section around antibiotic stewardship. You know, the utilization of antibiotics in a very pragmatic fashion amongst our patients. Can you describe why that's so critical in the context of the microbiome? Dr. Arielle Elkrief: Antibiotics can disrupt the gut microbiome composition. We know this from mouse studies, but also cohort studies of patients that are exposed to antibiotics. And most importantly, we know that patients who are exposed to antibiotics, either before or during the immunotherapy period, have significantly worse progression-free survival and overall survival to immunotherapy. And this is true for immunotherapy in the monotherapy setting, but also when combined with chemotherapy. What's striking is that when we look at patients who are just treated with chemotherapy, we don't see the negative outcome of antibiotics on outcome and progression-free survival and overall survival, suggesting that the negative impact of antibiotics on outcomes is really specific to immunotherapy backbones. The other important point is that this negative signal is maintained even after adjusting for standard prognostic variables in the specific malignancies that we're looking at. And then most importantly, at the mechanistic level, we were able to actually pinpoint the mechanism behind this antibiotic related dysbiosis. And we see this with a bloom of negative bacteria which induces a loss of MAd-CAM, which is an endothelial gut checkpoint immune marker, and that causes an efflux of immunosuppressive T cells, which are usually in the gut, to go straight into the tumor where they make the tumor unamenable to an immunotherapy response. And so now we finally have the mechanism as to why antibiotics are harmful and why we need to practice antibiotic stewardship. Dr. Sumanta (Monty) Pal: And just to be clear for the audience, I mean, if a patient needs antibiotics, they need antibiotics. But perhaps it just suggests that, and we have, I suppose, this predilection as oncologists, just for the minor cold or cough or what have you, we maybe should be a little bit more cognizant of whether or not antibiotics are truly necessary. Is that fair? Dr. Arielle Elkrief: Absolutely. So what we're advocating for is antibiotic stewardship, and this is the clear recommendation that we can make. So that means confirming a bacterial infection. If it's there and antibiotics are indicated, to choose the most narrow spectrum for the shortest course and constantly re-evaluate the indication of antibiotics. And of course, we need to work with our colleagues in infectious diseases who've done incredible work in antibiotic stewardship. And all along this process we also need to be mindful of other medications and polypharmacy, such as proton pump inhibitors or narcotics, for example, we think that these other medications which are frequently prescribed in our cancer population can also potentially have negative impacts on the microbiome and immunotherapy response. Dr. Sumanta (Monty) Pal: I think that's a terrific summary and big guidance for the audience. I promised you I'd tell you my favorite part of your article, and this is this huge table. I think the table is two and a half pages long, if I remember correctly, but it's an awesome table, and I highly recommend our audience to check this out. It lists literally every therapeutic trial for the microbiome under the sun. And so it begins with the approach of fecal microbiota transplant, which I'm going to ask you to tell us about in a second, but it also hinges on a lot of really cool sort of novel therapies, live bacterial products, mixes of different microbial products. Maybe take us through this whole approach of FMT (fecal microbiota transplantation). I actually wasn’t aware of the dozens of trials that you listed there in this space. It seems like it’s a very active area of research. Dr. Arielle Elkrief: Definitely. So, as you alluded to, FMT or fecal microbiota transplantation is the most well studied and direct way to modify the patient's microbiome. This technique aims to replace the patient's dysbiotic microbiome with that of a healthy microbiome, either from a healthy donor volunteer that's been heavily screened, or from a patient who experienced response to immunotherapy. And, as three landmark studies so far that have been published demonstrated the potential of FMT to reduce primary resistance or secondary resistance to immunotherapy, and this has been in melanoma. We also recently reported on the results of our , which looked at patients with lung cancer and melanoma. Once again, FMT, when combined with immunotherapy was safe and led to a higher proportion of responses than we would normally expect. We're now also looking at randomized trials that have come out. So the first being the in kidney cancer, which compared FMT plus pembrolizumab and axitinib to placebo in patients with RCC, and again, FMT was safe and feasible and also led to an increased progression-free survival at one year, meeting the study's primary endpoint. And so, so far, there's a wealth of data really showing the promise of FMT when combined with immunotherapy, and we're now in the process of conducting larger randomized trials, including in melanoma with the CCTG (Canada Cancer Trials Group) in our ME17 or , where we're going to be enrolling 128 patients with metastatic melanoma to receive FMT and standard of care immunotherapy compared to standard of care immunotherapy alone. Dr. Sumanta (Monty) Pal: You're very humble, so I’ve got to highlight for our audience. This was a mega grant that Arielle received to fund really the largest prospective exploration of FMT that will exist to date. So I'm really excited about that. I wish this was something we could participate in stateside. Before we jump into the other approach, which is live bacterial products and mixes thereof, where do you see FMT going? I think that one of the perceived challenges with FMT is that it's hard to implement, right? You need to have a really robust framework when it comes to gastroenterology, the preparation's challenging. Is there a way to envision FMT use being more generalized? Dr. Arielle Elkrief: Those are great questions. So we're lucky in Canada to work with pioneers in FMT, Michael Silverman, Saman Maleki, and John Lenehan in London, Ontario, who had this really robust FMT healthy donor screening program, which literally screens for every pathogen under the sun, and we haven't had any problems with feasibility or implementing FMT in Canada. But I think that once we're going to hopefully start doing larger scale, randomized phase three studies, that we might run into problems with scalability. And I think also with regards to reproducibility, and that's the feedback that we're getting from some regulatory authorities, especially at the level of the FDA, where there are some concerns around inter- and intra-donor variability because, of course, we can't guarantee that every fecal sample is going to be the same. So that has really pushed the field to think about other strategies, such as live biotherapeutic products which take modified FMT or bacteria from stools from either healthy donors or from responder patients and basically turn them into drugs that are regulated as drugs and can then be studied in the context of investigational new drugs or products. Dr. Sumanta (Monty) Pal: I like this and, you know, I do think that there's a future for it. We just have to kind of put our heads together and figure out how to get over all of these logistical hurdles, but, you know, I agree, I think your group and others have demonstrated, especially with this trial that you're fanning out all throughout Canada, that it can potentially be done. This is a topic that could probably go on for another couple of hours, right, especially based on the size of the table that you put together in this brilliant article, but tell us about live bacterial products or LBPs, as we call them these days. What's the current status, what's the future there? And maybe I'll give you less than two minutes here, although again, I realize it's a two-hour topic. Dr. Arielle Elkrief: You're probably better suited to speak about that because you've been one of the pioneers in terms of this. So we can think about LBPs in terms of single strain organisms, like CBM588 for an example, which your group did some amazing work in showing that, in a randomized setting, that this led to better responses than we would expect compared to just work with controls. We also know that LBPs can have multiple strains, up to 30. We're collaborating with a company called Cannabis Bioscience that is actually working on much larger communities of consortia. And so we're really excited about the direction that that's taking in terms of taking these LBPs and developing them from the drug perspective. In addition to LBPs, we know that there are other ways that we can change the microbiome, notably prebiotics, which are compounds which can have a beneficial impact on the microbiome. And one of these is camu camu, which I know your group is leading a looking at camu camu and kidney cancer, and we're excited to see how that compares to FMT or LBPs, because that might be a potentially scalable alternative. Dr. Sumanta (Monty) Pal: That's awesome. What a terrific overview, and that was less than two minutes. I don't know how you did it. That's terrific. Arielle, this has been such an insightful conversation. I just want to thank you for, again, a terrific in the ASCO Educational Book. I highly recommend all of our listeners to go there and check it out, and also for sharing all these terrific insights on the podcast today. Dr. Arielle Elkrief: Thank you so much, Monty.

Why Are Early-Onset GI Cancers on the Rise? 08/07/2025

Why Are Early-Onset GI Cancers on the Rise? Dr. Sumanta (Monty) Pal and Dr. Kimmie Ng discuss the disturbing rise of early-onset gastrointestinal cancers, the unique challenges faced by younger patients, and key research that is shedding light on potential drivers of early diagnoses in colorectal cancer. TRANSCRIPT Dr. Sumanta (Monty) Pal: Hello, everyone. I'm Dr. Monty Pal, and I'm a medical oncologist and professor and vice chair of medical oncology at the City of Hope Comprehensive Cancer Center in Los Angeles. I'm really delighted to welcome you all to the ASCO Daily News Podcast as the show's new host. I'll be bringing you discussions with leaders in the oncology space on a variety of topics. I've been working hard with the ASCO team on picking the ideal topics to bring to you, and I'm really delighted to introduce my first guest, a dear friend, Dr. Kimmie Ng, to discuss this huge problem that we're seeing nowadays of early-onset GI cancers. Dr. Ng is the associate chief of the Division of Gastrointestinal Oncology at the Dana-Farber Cancer Institute, and she's an associate professor of medicine at Harvard Medical School in Boston. She serves as co-director of the Colon and Rectal Cancer Program. She's also the founding director of the Young-Onset Colorectal Cancer Center at Dana-Farber. I'm sure we'll talk a little bit about that today. Just to note, our full disclosures are available in the transcript of this episode. Dr Ng, it's so great to have you on the podcast. Thanks so much for joining us. Dr. Kimmie Ng: Thank you so much for having me. It's great to be here. Dr. Sumanta (Monty) Pal: I'm going to refer to you as Kimmie, if you don't mind, for the rest of the podcast here. Please, we'll go by first names, if you don't mind. Your research has really done so much to help improve our understanding of early-onset GI cancers. You've done a lot of work to increase awareness in this space. I don't think there's a couple of months that passes by when I don't see you on television on Good Morning America or other shows really broadcasting this really critical message. I think there's a certain sensitivity that we all have to this issue, right? I mean, because receiving a cancer diagnosis at any age is very challenging, but I'm sure that young patients who face a colorectal cancer diagnosis have some very unique challenges. Could you give us a sense of some of those? Dr. Kimmie Ng: I think the other reason why so many people are interested in this and feel touched by this is that it's not just gastrointestinal cancers that are increasing in young people, but actually a multitude of different cancers have been rising in young individuals. And while it is difficult at any age to receive a cancer diagnosis, we do all know that young people getting a diagnosis like this do face unique challenges. Studies have shown that over 80% have children under the age of 18 when they are diagnosed with colorectal cancer, for example, under the age of 50. And many experience career and education disruptions. They are in what we call the ‘sandwich generation,’ where they're not only taking care of young families or starting to think about starting a young family, but they're also taking care of elderly parents. So it's just a very busy stage of life, and to then be facing a usually terminal cancer diagnosis, it is extremely challenging. The other factors that we've seen that seem to be unique or more prevalent in young patients is that there are higher levels of psychosocial distress, depression, and anxiety, and a majority of patients do need medical attention and treatment for those things, whether it's medication treatment or whether it's counseling or support from psychosocial oncologists. And so the other big issue is fertility. We know that so many of the treatments that these young patients receive do permanently and negatively impact fertility. And for a person who is young, who may still be trying to expand their family or again start a family, it is very important that these young patients do receive counseling about fertility preservation prior to starting treatment. Dr. Sumanta (Monty) Pal: You know, it's so interesting you bring this up, and I think about a patient who's in their 40s diagnosed with this disease. They're in the same demographic as I am, as you are. You know, I'm 44 years old, and you know, I'm thinking about my 11- and 12-year-old and my aging parents, right? I mean, the dilemmas that you highlighted are precisely what I'm facing in life, and it's so true, right? If I had to take my day-to-day and superimpose on that a colorectal cancer diagnosis, it would just be problematic in so many spheres, so many spheres. Dr. Kimmie Ng: Absolutely. And because we did think going into this, starting our Young-Onset Colorectal Cancer Center, that these patients will need unique supports, we did conduct a qualitative and held some focus groups of young-onset colorectal cancer patients as well as their caregivers. And we really identified four primary themes that I think reflect a lot of the experience of patients with cancer, no matter what type of cancer when they're diagnosed young. And the first is the need, feeling overwhelmed by the healthcare system, and the need for patient navigation. As we know, a lot of these patients are previously healthy before they're facing this very serious diagnosis. The second is the need for peer-to-peer support, where they really value connecting with other young patients going through a similar experience. The third, we talked about already, the need for kind of formal psychosocial support in the form of psychosocial oncologists or psychiatrists or social workers. And the last is an interest in research. They are really very invested in getting germline genetic testing as well as somatic genomic profiling to help guide their therapy. Dr. Sumanta (Monty) Pal: That's really encouraging to hear that they themselves are interested in participating in research. I mean, obviously, that's a great way to move the field forward. I view your area of work here as being such a vexing problem because no matter what way you slice it, young-onset colorectal cancer still remains a relatively small proportion of all diagnoses. So how do you go about studying this phenomenon? I mean, it must be challenging to really sort of investigate underlying causes when ostensibly this is still a small piece of the pie. Dr. Kimmie Ng: That is such a great question and is one of the challenges me and my research team think about every single day. As you mentioned, one of the major barriers is that although these cancers are rising in young people, the absolute number of patients being diagnosed is still relatively small, and if it's going to take large scale epidemiologic studies to really understand, for example, what the dietary and lifestyle risk factors are, you need a considerable number of patients in order to have enough power to reach definitive conclusions. And so this is where it is so important to collaborate. Any single institution is not going to see enough young-onset patients with colorectal cancer to be able to do this work on their own. And so I have really been intent on establishing an international prospective cohort study of patients with young-onset colorectal cancer so that we can increase the numbers of patients we partner with to try to answer these questions, but also so that we can study this on a global scale, because unfortunately this is not something that's just plaguing the United States. It is actually happening in multiple countries around the world. So that is one barrier. The second, I would say, is that we think it's early life exposures to whatever environmental factor it is that's causing the rise that is likely contributing the most. And so if you imagine how difficult it would be to start studying individuals from when they're children through adolescence, through adulthood, and then all the way until a cancer diagnosis is obtained, a study like that would take too long, would cost too much, and really wouldn't be feasible. So we need to think of alternative ways to really try and answer this question of what is driving this rise in young-onset colorectal cancer. Dr. Sumanta (Monty) Pal: Honestly, Kimmie, this seems like almost an unfair question in the context of what you just mentioned, the challenges in terms of ascertaining causality, right? I'll tell you, I cheated a little bit ahead of this podcast. Kimmie and I had dinner together in Los Angeles a couple months ago. She came out to deliver a Presidential Lectureship at City of Hope. We were delighted to have her. And we did have a couple of thoughts exchanged over potential drivers of these early diagnoses, leaning on perhaps one of the things that you and I are both interested in, the microbiome. But amongst all these things, vitamin D, microbiome, etc., and I won't hold you to this, do you have at least a general sense of what might be contributing to this early-onset phenomenon? Dr. Kimmie Ng: Yeah, as we talked about during my visit there to City of Hope, we do hypothesize that it is a complex interaction between our exposome, which is everything we are exposed to in our environment, which does include diet and lifestyle factors, interacting with host immunity and antitumor immunity, and as well as the microbiome and shaping the composition and diversity of the gut microbiome that are likely interacting to increase susceptibility to colorectal cancer at a younger age. And I will say one of the biggest discoveries, if you will, about what might be driving young-onset colorectal cancer was published a few months ago in Nature. And that identified a specific mutational signature caused by the genotoxin colibactin, which is often produced by an organism called pks+ E. coli, as being much more prevalent in younger patients with colorectal cancer than older patients. And so while it doesn't explain necessarily all of young-onset colorectal cancer and why it's rising, it does give us a clue that the microbiome is likely very important in perhaps why this is rising in young people. Dr. Sumanta (Monty) Pal: After you mentioned it, I went back and dove deep into that paper. I was fascinated, fascinated by the content there. And this is just a massive exploration across thousands of patients worldwide. So, I mean, if there is a way to get at least some hint of what's driving this phenomenon, I suppose that's it. So thank you for pointing me in the direction of that manuscript. Now that we've addressed the issue of diagnosis, if we could just, you know, verge on the topic of treatment, right? And this is something that I struggle with. When I have my young patients with kidney cancer, I don't know necessarily that my treatment paradigm changes a whole heck of a lot. I guess what I will say is I might be a little bit more aggressive about concepts like definitive management with surgery. I suppose perhaps their treatment tolerance is a little bit higher. But tell us about the setting of young-onset colorectal cancer. Is the philosophy any different in terms of the actual sort of management of these patients? Dr. Kimmie Ng: That's a great question, and actually I was honored to participate in the first international consensus guidelines group to try to come up with uniform recommendations for how to treat young patients with colorectal cancer. And you know, the overall consensus is just as you said, the medical care of these young patients right now is really not that much different than that of an older patient with colorectal cancer. There are a couple of distinctions. One is that all young patients should get germline genetic testing, given that there is a higher prevalence of pathogenic germline variants when you are diagnosed at a young age. And the second is what we've already talked about, which is that all young patients should be referred for counseling about fertility preservation prior to starting treatment. But otherwise, the chemotherapy regimens recommended, you know, surgery, radiation, all of that seems very similar to older patients. I will say that because most of our young patients with colorectal cancer are diagnosed with left-sided cancers, including rectal cancers, where some of the treatment may be morbid and result in lifelong complications, we do consider de-escalation of therapy and try to consider the long-term implications when it's safe to do so and won't compromise outcomes. The other concerning thing is that younger patients don't necessarily have a better prognosis than older patients. And multiple studies have shown this, that even though we both often treat younger patients more aggressively – they more often receive multi-agent chemotherapy, and more often undergo surgery and radiation – their survival is not necessarily correspondingly better than an older patient with colorectal cancer. So that suggests to us that maybe these cancers are indeed biologically different and perhaps more aggressive or perhaps less responsive to treatment. And so that is some of the focus of our research too, to understand what is actually different about these cancers and how they respond to treatment. Dr. Sumanta (Monty) Pal: It's such a paradox, isn't it, right? Because you just brought this to my mind. I guess on the one hand, our younger patients may be able to tolerate perhaps a greater amount of chemotherapy, targeted therapy, etc. But you're absolutely right. I mean, they do sort of have these lingering issues with side effects that may persist for much longer than the 80- or 90-year-old that we're treating in the clinic. I mean, these tend to be sort of lifelong consequences and sequelae that they're dealing with. So that really does evolve to be a challenge. You've kind of changed my mindset there a little bit. Dr. Kimmie Ng: Yeah, I do think survivorship issues and long-term complications of therapy do need to be considered, especially for a young person who we hope will live a very, very long time. And so part of the work that our Young-Onset Colorectal Cancer Center is doing, we are participating in a pilot navigation study where we navigate patients to survivorship earlier than we typically would, perhaps, for an older patient. And that's so we can get a head start on addressing some of those potential complications of therapy and hopefully mitigate them so that they don't become an issue long term. Dr. Sumanta (Monty) Pal: Do you think there's a role for de-escalation studies formally in these young populations of patients? Dr. Kimmie Ng: I think de-escalation studies are important overall, and specifically for locally advanced rectal cancer, which again is one of the most common types of colorectal cancer diagnosed in our young patients, there are certain populations that may be able to forgo the radiation treatment to the pelvis, for example, and there's more and more patients who now may become candidates for non-operative management where they may not necessarily need to have their rectal cancer surgically removed. And elimination potentially of both of those modalities of treatment can really avoid some of the most serious and morbid complications that often occur with these treatments. Dr. Sumanta (Monty) Pal: Really interesting. Now, this is not and will never be a political podcast, but you know, obviously we're dealing with the consequences of changes on funding and so forth that have evolved over time. And I think it's worth sort of speculating how the landscape of research may change on account of that. Could you comment perhaps a little bit on how some of the funding cuts that we've seen recently at the NIH might affect the body of work that you're so integrally involved in? Dr. Kimmie Ng: I am honestly very worried about the current funding environment. Colorectal cancer is the third most commonly diagnosed cancer among men and women in the United States and globally, and when you combine men and women together, the second leading cause of cancer death. But proportionally, we receive much less funding for colorectal cancer compared to other cancer types. And my thoughts have always been that perhaps this is because there is this stigma around colorectal cancer and maybe some of the symptoms associated with colorectal cancer. And so on top of that, to have additional challenges in obtaining funding, I worry what it will do to the pace of progress for especially young patients with this disease. Also, because of some new stipulations that perhaps international collaborations are being discouraged, I also worry about that aspect of it because young-onset colorectal cancer and gastrointestinal cancers in general is a global phenomenon happening in multiple countries around the world. And if we are to understand what the environmental factors are affecting the different rates of rise in these different countries, we do so much need that international collaboration. So yes, I am worried, and I do hope that conversations like this will spark an awareness of the need for more funding and continued funding into this disease. Dr. Sumanta (Monty) Pal: I will say that, and the audience can't see this because this is an audio program, but I'm wearing my Southwest Oncology shirt here, a SWOG, and it's one of the National Cancer Institute-funded cooperative groups. And you know, I was recently dismayed to find that, you know, funding got cut for international collaborations and enrollment in South America and Latin America. And this was traditionally actually a mainstay of our enrollment for many trials, including trials in rare cancers that present themselves in younger patients in the GU space. So, I completely agree with you. We've got to do something to address this funding issue to make sure that this body of work, both yours and mine, continues, without a doubt. Kimmie, this has been a delightful conversation. I really want to thank you for, you know, leading the charge in the young-onset colorectal cancer space, and you've done so much tremendous work here.

What Is Precision Palliative Care? Rethinking a Care Delivery Problem 07/31/2025

What Is Precision Palliative Care? Rethinking a Care Delivery Problem Dr. Joseph McCollom and Dr. Ramy Sedhom discuss precision palliative care, a new strategy that aims to align palliative care delivery with patient and caregiver needs instead of diagnosis alone. TRANSCRIPT ADN Podcast Episode 8-22 Transcript: What Is Precision Palliative Care? Rethinking a Care Delivery Problem Dr. Joseph McCollom: Hello and welcome to the ASCO Daily News Podcast. I'm your guest host, Dr. Joseph McCollom. I'm a GI medical oncologist and palliative oncologist at the Parkview Packnett Family Cancer Institute here in Fort Wayne, Indiana. So, the early benefits of palliative care for patients with cancer have been well documented, but there are challenges in terms of bandwidth to how do we provide this care, given the workforce shortages in the oncology field. So today, we'll be exploring a new opportunity known as precision palliative care, a strategy that aims to align care delivery with patient and caregiver needs and not just diagnosis alone. Joining me for this discussion is Dr. Ramy Sedhom. He is the medical director of oncology and palliative care at Penn Medicine Princeton Health and a clinical assistant professor of medicine at the University of Pennsylvania Perelman School of Medicine. Our full disclosures are available in the transcript of this episode. Dr. Sedhom, it's great to have you on the podcast today. Thank you so much for being here. Dr. Ramy Sedhom: Thank you, Joe. It's a pleasure to be here and lucky me to be in conversation with a colleague and friend. Yes, many of us have heard about the benefits of early palliative care. Trials have shown better quality of life, reduced symptoms, and potentially even improved survival. But as we know, the reality is translating that evidence into practice, which is really, really challenging. So Joe, both you and I know that not every patient can see palliative care, or I'd even argue should see palliative care, but that also means there are still many people with real needs who still fall through the cracks. That's why I'm really excited about today's topic, which we'll be discussing, which is precision palliative care. It's a growing shift in mindset from what's this patient's diagnosis or what's this patient's prognosis, to what matters most for this person in front of me right now and what are their individual care needs. I think, Joe, it's very exciting because the field is moving from a blanket approach to one tailored to meet people where they actually are. Dr. Joseph McCollom: Absolutely, Ramy. And I think from the early days when palliative care was kind of being introduced and trying to distinguish itself, I think one of the first models that came to clinicians' eyes was Jennifer Temel's in The New England Journal of Medicine in 2010. And her colleagues had really looked at early palliative care integration for patients with advanced non–small cell lung cancer. And in that era – this is a pre-immunotherapy era, very early targeted therapy era – the overall prognosis for those patients are similar to the population I serve as a GI medical oncologist, pancreatic cancer today. Typically, median overall survival of a year or less. And so, a lot of her colleagues really wanted her to track overall survival alongside quality of life and depression scores as a result of that. And it really was a landmark publication because not only did it show an improvement of quality of life, but it actually showed an improvement of overall survival. And that was really, I think, revolutionary at the time. You know, a lot of folks had talked about if this was a drug, the FDA would approve it. We all in GI oncology laugh about erlotinib, which got an FDA approval for a 2-week overall survival advantage. And so, it really kind of set the stage for a lot of us in early career who had a passion in the integration of palliative care and oncology. And I think a lot of the subsequent ASCO, NCCN, COC, Commission on Cancer, guidelines followed through with that. But I think what we realized is now we're kind of sitting center stage, there's still a lot of resource issues that if we sent a referral to palliative care for every single patient diagnosed with even an advanced cancer, we would have a significant workforce shortage issue. And so, Ramy, I was wondering if you could talk a little bit about how do we help center in on who are the right patients that are going to have the greatest benefit from a palliative care specialist intervention? Dr. Ramy Sedhom: Thanks, Joe. Great question. So you mentioned Dr. Temel's landmark 2010 published in the New England Journal of Medicine. And it is still a game changer in our field. The results of her work showed not only improved quality of life and mood, but I think very surprisingly at the time, a survival benefit for patients with lung cancer who had received early palliative care. That work, of course, has helped shape national guidelines, as you've shared, and it also helped define early, as within 8 weeks of diagnosis. But unfortunately, there remains a disconnect. So in clinical practice, using diagnosis or stage as the only referral trigger doesn't really match the needs that we see show up. And I think unfortunately, the other part is that approach creates a supply demand mismatch. We end up either referring more patients than palliative care teams can handle, or at the opposite extreme, we end up referring no one at all. So, I actually just wanted to quickly give, for example, two real world contrasts. So one center that I actually have friends who work in, tried as a very good quality improvement incentive, auto-refer all patients with stage IV pancreas cancer to palliative care teams. And while very well intentioned, they saw very quickly that in a two-month period, they had 30 new referrals. And on the palliative care side, there were only 15 available new patient slots. On the other hand, something that I often see in practice, is a situation where, for example, consider the case of a 90-year-old with a low-grade B-cell lymphoma. On paper, low-risk disease, but unfortunately, when you look under the microscope, this gentleman is isolated, has symptoms from his bulky adenopathy, and feels very overwhelmed by many competing illnesses. This is someone who, of course, may benefit from palliative care, but probably doesn't check the box. And I think this is where the model of precision palliative care steps in. It's not really about when was someone diagnosed or what is the prognosis or time-based criteria of their cancer, but it's really fundamentally asking the question of who needs help, what kind of help do they need, and how urgently do we need to provide this help? And I think precision palliative care really mirrors the logic and the philosophy of precision oncology. So just like we've made strides trying to match therapies to tumor biology, we also need to have the same attention and the same precision to match support to symptoms, to context of a patient situation and their caregiver, and also to their personal goals. So I think instead of a blanket referral, we really need to tailor care, the right support at the right moment for the right person to the right care teams. And I think to be more precise, there's really four core elements to allow us to do this well. So first, we really need to implement systematic screening. Let's use what we already have. Many of our centers have patient reported outcomes. The Commission on Cancer motivates us to use distress screening tools. And the EHR is there, but we do very little to flag and to surface unmet care needs. We have seen amazing work from people like Dr. Ethan Bash, who is the pioneer on patient-reported outcomes, and Dr. Ravi Parikh, who used to be my colleague at Penn, now at Emory, who show that you could use structured data and machine learning to identify some of these patient needs in real time. The second piece is after a systematic screening, we really need to build very clear referral pathways. One very good example is what the supportive care team at MD Anderson has done, of course, led by Dr. Eduardo Brera and Dr. David Huey, where they have, for example, designed condition-specific triggers. Urgent referrals, for example, to palliative care for severe symptoms, where they talk about it like a rapid response team. They will see them within 72 hours of the flag. But at the same time, if the unmet need is a caregiver distress, perhaps the social work referral is the first part of the palliative care intervention that needs to be placed. And I think this helps create both clarity and consistency but also it pays attention to that provider and availability demand mismatch. Third, I really think we need to triage smartly. As mentioned in the prior example, not every patient needs every team member of the palliative care team. Some benefit most from the behavioral health intervention. Others might benefit from chaplaincy or the clinician for symptom management. And I think aligning intensity with complexity helps us use our teams wisely. Unfortunately, the greatest barrier in all of our health care systems is time and time availability. And I think this is one strategic approach that I have not yet seen used very wisely. And fourth, I really think we need to embrace interdisciplinary care and change our healthcare systems to focus more on value. So this isn't about more consults or RVUs. I think it's really about leveraging our team strengths. Palliative care teams or supportive care teams usually are multidisciplinary in their core. They often have psychologists, social workers, sometimes they have nurse navigators. And I think all of these are really part of that engine of whole person care. But unfortunately, we still are not set up in care delivery systems that unfortunately to this day still model fee for service where the clinician or the physician visit is the only quote unquote real value add. Hopefully as our healthcare systems focus more on delivery and on value, this might help really embrace the structure to bring through the precision palliative care approach. Dr. Joseph McCollom: No, I love those points. You know, we talk frequently in the interdisciplinary team about how a social worker can spend 5 minutes doing something that I could not as a physician spend an hour doing. But does every patient need every member every time? And how do we work as a unified body to deliver that dose of palliative care, specialized palliative care to those right patients and match them? And I think that perfect analogy is in oncology as a medical oncologist, frequently I'm running complex next-generation sequencing paneling on patients' tumors, trying to find out is there a genetic weakness? Is there a susceptibility to a targeted therapy or an immunotherapy so that I can match and do that precision oncology, right patient to the right drug? Similarly, we need to continue to analyze and find these innovative ways like you've talked about, PROs, EHR flags, machine learning tools, to find those right patients and match them to the right palliative care interdisciplinary team members for them. I know we both get to work in oncology spaces and palliative and supportive spaces in our clinical practice. Share a little bit, if you could, Ramy, about what that looks like for your practice. How do you find those right patients? And how do you then intervene with that right palliative oncology dose? Dr. Ramy Sedhom: So Joe, when I first started in this space as a junior faculty, one thing became immediately clear. I think if we rely solely on physicians to identify the patients for palliative care, we're unfortunately going to be very limited by what we individually, personally observe. And I think that's what reflects the reality that many patients have real needs that go unseen. So over the past few years, I've really worked with a lot of my colleagues to really work the health system to change that. The greatest partnership I've personally had has been working with our informatics team to build a real time EHR integrated dashboard that I think helps us give us a broader view of patient needs. What we really think of as the population health perspective. Our dashboard at Penn, for example, pulls in structured data like geriatric assessment results, PHQ-4 screens, patient reported outcomes, whether or not they've been hospitalized, whether or not these hospitalizations are frequent and recurrent. And I think it's allowed us to really move from a reactive approach to one that's more proactive. So let me give you a practical example. So we have embedded in our cancer care team, psycho-oncologists. They share the same clinic space, they're right down the hall. And we actually use this shared dashboard to review weekly trends in distress scores and patient reported outcomes. And oftentimes, if they see a spike in anxiety or worsening symptoms like depression, they'll reach out to me and say, “Hey, I noticed Mrs. Smith reported feeling very anxious today. Do you think it'd be helpful if I joined you for her visit?” And I think that's how we could really use data and teamwork to offer and maximize the right support at the right time. Like many of our other healthcare systems, we also have real-time alerts for hospitalizations. And I think like Dr. Temel’s most recent , which we'll discuss at some point, I'm sure, it's another key trigger for vulnerability. I think whenever someone's admitted or discharged, we try to coordinate with our palliative care colleagues to assess do they need follow-up and in what timeline. And we know that these are common triggers, progression of disease, hospitalizations, drops in quality-of-life. And it's actually surprisingly simple to implement once you set up the right care structures. And I think these systems don't just help patients, which is what I quickly learned. They also help us as clinicians too. Before we expanded our team, I often felt this weight, especially as someone dual trained in oncology and palliative medicine, as trying to be everything to everyone. I remember one patient in particular, a young woman with metastatic breast cancer who was scheduled for a routine pre-chemo visit with me. Unfortunately, on that day, she had a very dramatic change in function. We whisked her down to x-ray and it revealed a pretty large pathologic fracture in her femur. And suddenly what was scheduled as a 30-minute visit became a very complex conversation around prognosis, urgent need for surgery and many, many life changes. And when I looked at my Epic list, I had a full waiting room. And thankfully, because we have embedded palliative care in our team, I was able to bring in Dr. Collins, the physician who I work with closely, immediately. She spent the full hour with the patient while I was able to continue seeing other patients that morning. And I think that's what team-based care makes possible. It's not just more hands on deck but really optimizing the support the patient needs on each individual day. And I think last, we're also learning a lot from behavioral science. So many institutions like Penn, Stanford, Massachusetts General, they've experimented with a lot of really interesting prompts in the EHR. One of them, for example, is the concept of nodes or the concept of prompt questions. Like, do you think this patient would benefit from a supportive care referral? And I think these low-level nudges, in a sense, can actually really dramatically increase the uptake of palliative care because it makes what's relevant immediately salient and visible to the practicing physician. So I think the key, if I had to maybe finish off with a simple message: It's not flashy tech, it's not massive change against staffing, but it's having a local champion and it's working smarter. It's asking the questions of how can we do this better and setting up the systems to make them more sustainable. Dr. Joseph McCollom: I appreciate you talking about this because I think a lot of folks want to put the wheels on in some way and they don't know where to get started. And so I think some of the models that you've been able to create, being able to track patients, screen your population, find the right individuals, and then work within that team to be able to extend, I think when you have an embedded palliative care specialist in your clinic, they expand your practice as a medical oncologist. And so you can make that warm handoff. And that patient and that caregiver, when they view the experience, they don't view you as a medical oncologist, someone else as a palliative care specialist, they view that team approach. And they said, "The team, my cancer team took care of me." And I think we can really harness a lot of the innovative technological advancements in our EHR to be able to prompt us in this work. I know that Dr. Temel had kind of set the stage for early palliative care intervention, and you did mention her stepped palliative care trial. Where do you see some of the future opportunities as we continue to push the needle forward as oncologists and palliative care specialists? What do you see as being the next step? Dr. Ramy Sedhom: So for those who are not familiar with the , again, work by Dr. Temel, I think it's really important to explain not just the study itself, but I think more importantly, what it's representing for the future of our field. First, I really want to acknowledge Dr. Temel, who is a trailblazer in palliative oncology. Her work has not only shaped how we think about timing and delivery, but really about the value of supportive care. And more importantly, I think for all the young trainees listening, she had shown that rigorous randomized trials in palliative care are possible and meaningful. And I think for me, one quick learning point is that you could be an oncologist and lead this impactful research. And she's inspired many and many of us. Now let's quickly transition to her study. So in this trial, the stepped palliative care trial, patients with advanced lung cancer were randomized into two groups. One group followed the model from her landmark 2010 New England Journal of Medicine paper, which was structured monthly palliative care visits, again, within eight weeks of diagnosis. The second group, which is in this study, the intervention or the stepped palliative care group, received a single early palliative care visit. Think of this as a meet and greet. And then care was actually stepped up. If one of three clinical triggers happened. One, a decline in patient reported quality of life as measured by PROs. Two, disease progression, or three, hospitalization. And the findings which were presented at ASCO 2024 were striking. Clinical outcomes, very similar between the two groups. And this included quality-of-life, end-of-life communication, and resource use. But I think the take-home point is that the number of palliative care visits in the stepped group was significantly lower. So in other words, same impact and fewer visits. This was a very elegant example of how we can model precision palliative care, right sizing patient care based on patient need. So where do we go from here? I think if we want this model to take root nationally, we really need to pull on three key levers: healthcare systems, healthcare payment, and healthcare culture. So from a system alignment, unfortunately, as mentioned too often, the solution to gaps in palliative care is we need more clinicians. And while yes, that's partly true, it's actually not the full picture. I think what we first need to do and what's more likely to be achieved is to develop systems that focus on building the infrastructure that maximizes the reach of our existing care teams. So this means investing in nurse navigation, real-time dashboards with patient-reported outcomes and EHR flags, and again, matching triage protocols where intensity matches... /episode/index/show/ascodaily/id/37607040

From Clinic to Clinical Trials: Responsible AI Integration in Oncology 07/10/2025

From Clinic to Clinical Trials: Responsible AI Integration in Oncology Dr. Paul Hanona and Dr. Arturo Loaiza-Bonilla discuss how to safely and smartly integrate AI into the clinical workflow and tap its potential to improve patient-centered care, drug development, and access to clinical trials. TRANSCRIPT Dr. Paul Hanona: Hello, I'm Dr. Paul Hanona, your guest host of the ASCO Daily News Podcast today. I am a medical oncologist as well as a content creator , and I’m delighted to be joined today by Dr. Arturo Loaiza-Bonilla, the chief of hematology and oncology at St. Luke’s University Health Network. Dr. Bonilla is also the co-founder and chief medical officer at Massive Bio, an AI-driven platform that matches patients with clinical trials and novel therapies. Dr. Loaiza-Bonilla will share his unique perspective on the potential of artificial intelligence to advance precision oncology, especially through clinical trials and research, and other key advancements in AI that are transforming the oncology field. Our full disclosures are available in the transcript of the episode. Dr. Bonilla, it's great to be speaking with you today. Thanks for being here. Dr. Arturo Loaiza-Bonilla: Oh, thank you so much, Dr. Hanona. Paul, it’s always great to have a conversation. Looking forward to a great one today. Dr. Paul Hanona: Absolutely. Let’s just jump right into it. Let’s talk about the way that we see AI being embedded in our clinical workflow as oncologists. What are some practical ways to use AI? Dr. Arturo Loaiza-Bonilla: To me, responsible AI integration in oncology is one of those that's focused on one principle to me, which is clinical purpose is first, instead of the algorithm or whatever technology we’re going to be using. If we look at the best models in the world, they’re really irrelevant unless we really solve a real day-to-day challenge, either when we’re talking to patients in the clinic or in the infusion chair or making decision support. Currently, what I’m doing the most is focusing on solutions that are saving us time to be more productive and spend more time with our patients. So, for example, we’re using ambient AI for appropriate documentation in real time with our patients. We’re leveraging certain tools to assess for potential admission or readmission of patients who have certain conditions as well. And it’s all about combining the listening of physicians like ourselves who are end users, those who create those algorithms, data scientists, and patient advocates, and even regulators, before they even write any single line of code. I felt that on my own, you know, entrepreneurial aspects, but I think it's an ethos that we should all follow. And I think that AI shouldn't be just bolted on later. We always have to look at workflows and try to look, for example, at clinical trial matching, which is something I'm very passionate about. We need to make sure that first, it's easier to access for patients, that oncologists like myself can go into the interface and be able to pull the data in real time when you really need it, and you don't get all this fatigue alerts. To me, that's the responsible way of doing so. Those are like the opportunities, right? So, the challenge is how we can make this happen in a meaningful way – we're just not reacting to like a black box suggestion or something that we have no idea why it came up to be. So, in terms of success – and I can tell you probably two stories of things that we know we're seeing successful – we all work closely with radiation oncologists, right? So, there are now these tools, for example, of automated contouring in radiation oncology, and some of these solutions were brought up in different meetings, including the last ASCO meeting. But overall, we know that transformer-based segmentation tools; transformer is just the specific architecture of the machine learning algorithm that has been able to dramatically reduce the time for colleagues to spend allotting targets for radiation oncology. So, comparing the target versus the normal tissue, which sometimes it takes many hours, now we can optimize things over 60%, sometimes even in minutes. So, this is not just responsible, but it's also an efficiency win, it's a precision win, and we're using it to adapt even mid-course in response to tumor shrinkage. Another success that I think is relevant is, for example, on the clinical trial matching side. We've been working on that and, you know, I don't want to preach to the choir here, but having the ability for us to structure data in real time using these tools, being able to extract information on biomarkers, and then show that multi-agentic AI is superior to what we call zero-shot or just throwing it into ChatGPT or any other algorithm, but using the same tools but just fine-tuned to the point that we can be very efficient and actually reliable to the level of almost like a research coordinator, is not just theory. Now, it can change lives because we can get patients enrolled in clinical trials and be activated in different places wherever the patient may be. I know it's like a long answer on that, but, you know, as we talk about responsible AI, that's important. And in terms of what keeps me up at night on this: data drift and biases, right? So, imaging protocols, all these things change, the lab switch between different vendors, or a patient has issues with new emerging data points. And health systems serve vastly different populations. So, if our models are trained in one context and deployed in another, then the output can be really inaccurate. So, the idea is to become a collaborative approach where we can use federated learning and patient-centricity so we can be much more efficient in developing those models that account for all the populations, and any retraining that is used based on data can be diverse enough that it represents all of us and we can be treated in a very good, appropriate way. So, if a clinician doesn't understand why a recommendation is made, as you probably know, you probably don't trust it, and we shouldn't expect them to. So, I think this is the next wave of the future. We need to make sure that we account for all those things. Dr. Paul Hanona: Absolutely. And even the part about the clinical trials, I want to dive a little bit more into in a few questions. I just kind of wanted to make a quick comment. Like you said, some of the prevalent things that I see are the ambient scribes. It seems like that's really taken off in the last year, and it seems like it's improving at a pretty dramatic speed as well. I wonder how quickly that'll get adopted by the majority of physicians or practitioners in general throughout the country. And you also mentioned things with AI tools regarding helping regulators move things quicker, even the radiation oncologist, helping them in their workflow with contouring and what else they might have to do. And again, the clinical trials thing will be quite interesting to get into. The first question I had subsequent to that is just more so when you have large datasets. And this pertains to two things: the that you published recently regarding different ways to use AI in the space of oncology referred to drug development, the way that we look at how we design drugs, specifically anticancer drugs, is pretty cumbersome. The steps that you have to take to design something, to make sure that one chemical will fit into the right chemical or the structure of the molecule, that takes a lot of time to tinker with. What are your thoughts on AI tools to help accelerate drug development? Dr. Arturo Loaiza-Bonilla: Yes, that's the Holy Grail and something that I feel we should dedicate as much time and effort as possible because it relies on multimodality. It cannot be solved by just looking at patient histories. It cannot be solved by just looking at the tissue alone. It's combining all these different datasets and being able to understand the microenvironment, the patient condition and prior treatments, and how dynamic changes that we do through interventions and also exposome – the things that happen outside of the patient's own control – can be leveraged to determine like what's the best next step in terms of drugs. So, the ones that we heard the news the most is, for example, the Nobel Prize-winning [for Chemistry awarded to Demis Hassabis and John Jumper for] AlphaFold, an AI system that predicts protein structures right? So, we solved this very interesting concept of protein folding where, in the past, it would take the history of the known universe, basically – what's called the Levinthal's paradox – to be able to just predict on amino acid structure alone or the sequence alone, the way that three-dimensionally the proteins will fold. So, with that problem being solved and the Nobel Prize being won, the next step is, “Okay, now we know how this protein is there and just by sequence, how can we really understand any new drug that can be used as a candidate and leverage all the data that has been done for many years of testing against a specific protein or a specific gene or knockouts and what not?” So, this is the future of oncology and where we're probably seeing a lot of investments on that. The key challenge here is mostly working on the side of not just looking at pathology, but leveraging this digital pathology with whole slide imaging and identifying the microenvironment of that specific tissue. There's a number of efforts currently being done. One isn't just H&E, like hematoxylin and eosin, slides alone, but with whole imaging, now we can use expression profiles, spatial transcriptomics, and gene whole exome sequencing in the same space and use this transformer technology in a multimodality approach that we know already the slide or the pathology, but can we use that to understand, like, if I knock out this gene, how is the microenvironment going to change to see if an immunotherapy may work better, right? If we can make a microenvironment more reactive towards a cytotoxic T cell profile, for example. So, that is the way where we're really seeing the field moving forward, using multimodality for drug discovery. So, the FDA now seems to be very eager to support those initiatives, so that's of course welcome. And now the key thing is the investment to do this in a meaningful way so we can see those candidates that we're seeing from different companies now being leveraged for rare disease, for things that are going to be almost impossible to collect enough data, and make it efficient by using these algorithms that sometimes, just with multiple masking – basically, what they do is they mask all the features and force the algorithm to find solutions based on the specific inputs or prompts we're doing. So, I'm very excited about that, and I think we're going to be seeing that in the future. Dr. Paul Hanona: So, essentially, in a nutshell, we're saying we have the cancer, which is maybe a dandelion in a field of grass, and we want to see the grass that's surrounding the dandelion, which is the pathology slides. The problem is, to the human eye, it's almost impossible to look at every single piece of grass that's surrounding the dandelion. And so, with tools like AI, we can greatly accelerate our study of the microenvironment or the grass that's surrounding the dandelion and better tailor therapy, come up with therapy. Otherwise, like you said, to truly generate a drug, this would take years and years. We just don't have the throughput to get to answers like that unless we have something like AI to help us. Dr. Arturo Loaiza-Bonilla: Correct. Dr. Paul Hanona: And then, clinical trials. Now, this is an interesting conversation because if you ever look up our national guidelines as oncologists, there's always a mention of, if treatment fails, consider clinical trials. Or in the really aggressive cancers, sometimes you might just start out with clinical trials. You don't even give the standard first-line therapy because of how ineffective it is. There are a few issues with clinical trials that people might not be aware of, but the fact that the majority of patients who should be on clinical trials are never given the chance to be on clinical trials, whether that's because of proximity, right, they might live somewhere that's far from the institution, or for whatever reason, they don't qualify for the clinical trial, they don't meet the strict inclusion criteria. But a reason you mentioned early on is that it's simply impossible for someone to be aware of every single clinical trial that's out there. And then even if you are aware of those clinical trials, to actually find the sites and put in the time could take hours. And so, how is AI going to revolutionize that? Because in my mind, it's not that we're inventing a new tool. Clinical trials have always been available. We just can't access them. So, if we have a tool that helps with access, wouldn't that be huge? Dr. Arturo Loaiza-Bonilla: Correct. And that has been one of my passions. And for those who know me and follow me and we've spoke about it in different settings, that's something that I think we can solve. This other paradox, which is the clinical trial enrollment paradox, right? We have tens of thousands of clinical trials available with millions of patients eager to learn about trials, but we don't enroll enough and many trials close to accrual because of lack of enrollment. It is completely paradoxical and it's because of that misalignment because patients don't know where to go for trials and sites don't know what patients they can help because they haven't reached their doors yet. So, the solution has to be patient-centric, right? We have to put the patient at the center of the equation. And that was precisely what we had been discussing during the ASCO meeting. There was an ASCO where we talked about digital prescreening hubs, where we, in a patient-centric manner, the same way we look for Uber, Instacart, any solution that you may think of that you want something that can be leveraged in real time, we can use these real-world data streams from the patient directly, from hospitals, from pathology labs, from genomics companies, to continuously screen patients who can match to the inclusion/exclusion criteria of unique trials. So, when the patient walks into the clinic, the system already knows if there's a trial and alerts the site proactively. The patient can actually also do decentralization. So, there's a number of decentralized clinical trial solutions that are using what I call the “click and mortar” approach, which is basically the patient is checking digitally and then goes to the site to activate. We can also have the click and mortar in the bidirectional way where the patient is engaged in person and then you give the solution like the ones that are being offered on things that we're doing at Massive Bio and beyond, which is having the patient to access all that information and then they make decisions and enroll when the time is right. As I mentioned earlier, there is this concept drift where clinical trials open and close, the patient line of therapy changes, new approvals come in and out, and sites may not be available at a given time but may be later. So, having that real-time alerts using tools that are able already to extract data from summarization that we already have in different settings and doing this natural language ingestion, we can not only solve this issue with manual chart review, which is extremely cumbersome and takes forever and takes to a lot of one-time assessments with very high screen failures, to a real-time dynamic approach where the patient, as they get closer to that eligibility criteria, they get engaged. And those tools can be built to activate trials, audit trials, and make them better and accessible to patients. And something that we know is, for example, 91%-plus of Americans live close to either a pharmacy or an imaging center. So, imagine that we can potentially activate certain of those trials in those locations. So, there's a number of pharmacies, special pharmacies, Walgreens, and sometimes CVS trying to do some of those efforts. So, I think the sky's the limit in terms of us working together. And we've been talking with corporate groups, they're all interested in those efforts as well, to getting patients digitally enabled and then activate the same way we activate the NCTN network of the corporate groups, that are almost just-in-time. You can activate a trial the patient is eligible for and we get all these breakthroughs from the NIH and NCI, just activate it in my site within a week or so, as long as we have the understanding of the protocol. So, using clinical trial matching in a digitally enabled way and then activate in that same fashion, but not only for NCTN studies, but all the studies that we have available will be the key of the future through those prescreening hubs. So, I think now we're at this very important time where collaboration is the important part and having this silo-breaking approach with interoperability where we can leverage data from any data source and from any electronic medical records and whatnot is going to be essential for us to move forward because now we have the tools to do so with our phones, with our interests, and with the multiple clinical trials that are coming into the pipelines. Dr. Paul Hanona: I just want to point out that the way you described the process involves several variables that practitioners often don't think about. We don't realize the 15 steps that are happening in the background. But just as a clarifier, how much time is it taking now to get one patient enrolled on a clinical trial? Is it on the order of maybe 5 to 10 hours for one patient by the time the manual chart review happens, by the time the matching happens, the calls go out, the sign-up, all this? And how much time do you think a tool that could match those trials quicker and get you enrolled quicker could save? Would it be maybe an hour instead of 15 hours? What's your thought process on that? Dr. Arturo Loaiza-Bonilla: Yeah, exactly. So one is the matching, the other one is the enrollment, which, as you mentioned, is very important. So, it can take, from, as you said, probably between 4 days to sometimes 30 days. Sometimes that's how long it takes for all the things to be parsed out in terms of logistics and things that could be done now agentically. So, we can use agents to solve those different steps that may take multiple individuals. We can just do it as a supply chain approach where all those different steps can be done by a single agent in a simultaneous fashion and then we can get things much faster. With an AI-based solution using these frontier models and multi-agentic AI – and we presented some of this data in ASCO as well – you can do 5,000 patients in an hour, right? So, just enrolling is going to be between an hour and maximum enrollment, it could be 7 days for those 5,000 patients if it was done at scale in a multi-level approach where we have all the trials available. Dr. Paul Hanona: No, definitely a very exciting aspect of our future as oncologists. It's one thing to have really neat, novel mechanisms of treatment, but what good is it if we can't actually get it to people who need it? I'm very much looking for the future of that. One of the last questions I want to ask you is another prevalent way that people use AI is just simply looking up questions, right? So, traditionally, the workflow for oncologists is maybe going on national guidelines and looking up the stage of the cancer and seeing what treatments are available and then referencing the papers and looking at who was included, who wasn't included, the side effects to be aware of, and sort of coming up with a decision as to how to treat a cancer patient. But now, just in the last few years, we've... /episode/index/show/ascodaily/id/37259290

Immunotherapy at ASCO25: Drug Development, Melanoma Treatment, and More 06/27/2025

Immunotherapy at ASCO25: Drug Development, Melanoma Treatment, and More Dr. Diwakar Davar and Dr. Jason Luke discuss novel agents in melanoma and other promising new data in the field of immunotherapy that were presented at the 2025 ASCO Annual Meeting. TRANSCRIPT Dr. Diwakar Davar: Hello. My name is Diwakar Davar, and I am welcoming you to the ASCO Daily News Podcast. I'm an associate professor of medicine and the clinical director of the Melanoma and Skin Cancer Program at the University of Pittsburgh’s Hillman Cancer Center. Today, I'm joined by my colleague and good friend, Dr. Jason Luke. Dr. Luke is a professor of medicine. He is also the associate director of clinical research and the director of the Phase 1 IDDC Program at the University of Pittsburgh's Hillman Cancer Center. He and I are going to be discussing some key advancements in melanoma and skin cancers that were presented at the 2025 ASCO Annual Meeting. Our full disclosures are available in the transcript of this episode. Jason, it is great to have you back on the podcast. Dr. Jason Luke: Thanks again so much for the opportunity, and I'm really looking forward to it. Dr. Diwakar Davar: Perfect. So we will go ahead and start talking a little bit about a couple of key abstracts in both the drug development immunotherapy space and the melanoma space. The first couple of abstracts, the first two, will cover melanoma. So, the first is , which was essentially the primary results of . RELATIVITY-098 was a phase 3 trial that compared nivolumab plus relatlimab in a fixed-dose combination against nivolumab alone for the adjuvant treatment of resected high-risk disease. Jason, do you want to maybe give us a brief context of what this is? Dr. Jason Luke: Yeah, it's great, thanks. So as almost all listeners, of course, will be aware, the use of anti–PD-1 immunotherapies really revolutionized melanoma oncology over the last 10 to 15 years. And it has become a standard of care in the adjuvant setting as well. But to review, in patients with stage III melanoma, treatment can be targeted towards BRAF with BRAF and MEK combination therapy, where that's relevant, or anti–PD-1 with nivolumab or pembrolizumab are a standard of care. And more recently, we've had the development of neoadjuvant approaches for palpable stage III disease. And in that space, if patients present, based on two different studies, either pembrolizumab or nivolumab plus ipilimumab can be given prior to surgery for somewhere in the 6- to 9-week range. And so all of these therapies have improved time-to-event endpoints, such as relapse-free or event-free survival. It's worth noting, however, that despite those advances, we've had a couple different trials now that have actually failed in this adjuvant setting, most high profile being the study, which looked at nivolumab plus ipilimumab and unfortunately was a negative study. So, with RELATIVITY-047, which was the trial of nivolumab plus relatlimab that showed an improvement in progression-free survival for metastatic disease, there's a lot of interest, and we've been awaiting these data for a long time for RELATIVITY-098, which, of course, is this adjuvant trial of LAG-3 blockade with relatlimab plus nivolumab. Dr. Diwakar Davar: Great. So with that, let's briefly discuss the trial design and the results. So this was a randomized, phase 3, blinded study, so double-blinded, so neither the investigators knew what the patients were getting, nor did the patients know what they were getting. The treatment investigational arm was nivolumab plus relatlimab in the fixed-dose combination. So that's the nivolumab standard fixed dose with relatlimab that was FDA approved in . And the control arm was nivolumab by itself. The duration of treatment was 1 year. The patient population consisted of resected high-risk stage III or IV patients. The primary endpoint was investigator-assessed RFS. Stage and geography were the standard stratifying factors, and they were included, and most of the criteria were balanced across both arms. What we know at this point is that the 2-year RFS rate was 64% and 62% in the nivolumab and nivolumab-combination arms, respectively. The 2-year DMFS rate was similarly equivalent: 76% with nivolumab monotherapy, 73% with the combination. And similar to what you had talked about with CheckMate 915, unfortunately, the addition of LAG-3 did not appear to improve the RFS or DMFS compared to control in this patient population. So, tell us a little bit about your take on this and what do you think might be the reasons why this trial was negative? Dr. Jason Luke: It's really unfortunate that we have this negative phase 3 trial. There had been a lot of hope that the combination of nivolumab with relatlimab would be a better tolerated combination that increased the efficacy. So in the metastatic setting, we do have 047, the study that demonstrated nivolumab plus relatlimab, but now we have this negative trial in the adjuvant setting. And so as to why exactly, I think is a complicated scenario. You know, when we look at the hazard ratios for relapse-free survival, the primary endpoint, as well as the secondary endpoints for distant metastasis-free survival, we see that the hazard ratio is approximately 1. So there's basically no difference. And that really suggests that relatlimab in this setting had no impact whatsoever on therapeutic outcomes in terms of efficacy. Now, it's worth noting that there was a biomarker subanalysis that was presented in conjunction with these data that looked at some immunophenotyping, both from circulating T cells, CD8 T cells, as well as from the tumor microenvironment from patients who were treated, both in the previous metastatic trial, the RELATIVITY-047 study, and now in this adjuvant study in the RELATIVITY-098 study. And to briefly summarize those, what was identified was that T cells in advanced melanoma seemed to have higher expression levels of LAG-3 relative to T cells that are circulating in patients that are in the adjuvant setting. In addition to that, there was a suggestion that the magnitude of increase is greater in the advanced setting versus adjuvant. And the overall summary of this is that the suggested rationale for why this was a negative trial may have been that the target of LAG-3 is not expressed as highly in the adjuvant setting as it is in the metastatic setting. And so while the data that were presented, I think, support this kind of an idea, I am a little bit cautious that this is actually the reason for why the trial was negative, however. I would say we're not really sure yet as to why the trial was negative, but the fact that the hazard ratios for the major endpoints were essentially 1 suggests that there was no impact whatsoever from relatlimab. And this really makes one wonder whether or not building on anti–PD-1 in the adjuvant setting is feasible because anti–PD-1 works so well. You would think that even if the levels of LAG-3 expression were slightly different, you would have seen a trend in one direction or another by adding a second drug, relatlimab, in this scenario. So overall, I think it's an unfortunate circumstance that the trial is negative. Clearly there's going to be no role for relatlimab in the adjuvant setting. I think this really makes one wonder about the utility of LAG-3 blockade and how powerful it really can be. I think it's probably worth pointing out there's another adjuvant trial ongoing now of a different PD-1 and LAG-3 combination, and that's cemiplimab plus fianlimab, a LAG-3 antibody that's being dosed from another trial sponsor at a much higher dose, and perhaps that may make some level of difference. But certainly, these are unfortunate results that will not advance the field beyond where we were at already. Dr. Diwakar Davar: And to your point about third-generation checkpoint factors that were negative, I guess it's probably worth noting that a trial that you were involved with, , that evaluated the PD-1 TIGIT co-formulation of vibostolimab, MK-4280A, was also, unfortunately, similarly negative. So, to your point, it's not clear that all these third-generation receptors are necessarily going to have the same impact in the adjuvant setting, even if they, you know, for example, like TIGIT, and they sometimes may not even have an effect at all in the advanced cancer setting. So, we'll see what the phase 3 trial, that's the Regeneron cemiplimab/fianlimab versus pembrolizumab control with cemiplimab with fianlimab at two different doses, we'll see how that reads out. But certainly, as you've said, LAG-3 does not, unfortunately, appear to have an impact in the adjuvant setting. So let's move on to . This is the primary analysis of EORTC-2139-MG or the trial. This was a randomized trial of encorafenib and binimetinib, which we will abbreviate as enco-bini going forward, compared to placebo in high-risk stage II setting in melanoma in patients with BRAF V600E or K mutant disease. So Jason, you know, you happen to know one or two things about the resected stage II setting, so maybe contextualize the stage II setting for us based on the trials that you've led, , as well as , set us up to talk about Columbus-AD. Dr. Jason Luke: Thanks for that introduction, and certainly stage II disease has been something I've worked a lot on. The rationale for that has been that building off of the activity of anti–PD-1 in metastatic melanoma and then seeing the activity in stage III, like we just talked about, it was a curious circumstance that dating back about 7 to 8 years ago, there was no availability to use anti–PD-1 for high-risk stage II patients, even though the risk of recurrence and death from melanoma in the context of stage IIB and IIC melanoma is in fact similar or actually higher than in stage IIIA or IIIB, where anti–PD-1 was approved. And in that context, a couple of different trials that you alluded to, the Keynote-716 study that I led, as well as the CheckMate 76K trial, evaluated pembrolizumab and nivolumab, respectively, showing an improvement in relapse-free and distant metastasis-free survival, and both of those agents have subsequently been approved for use in the adjuvant setting by the US FDA as well as the European Medicines Agency. So bringing then to this abstract, throughout melanoma oncology, we've seen that the impact of anti–PD-1 immunotherapy versus BRAF and MEK-targeted therapy have had very similar outcomes on a sort of comparison basis, both in frontline metastatic and then in adjuvant setting. So it was a totally reasonable question to ask: Could we use adjuvant BRAF and MEK inhibitor therapy? And I think all of us expected the answer would be yes. As we get into the discussion of the trial, I think the unfortunate circumstance was that the timing of this clinical trial being delayed somewhat, unfortunately, made it very difficult to accrue the trial, and so we're going to have to try to read through the tea leaves sort of, based on only a partially complete data set. Dr. Diwakar Davar: So, in terms of the results, they wanted to enroll 815 patients, they only enrolled 110. The RFS and DMFS were marginally improved in the treatment arm but certainly not significantly, which is not surprising because the trial had only accrued 16% to 18% of its complete accrual. As such, we really can't abstract from the stage III data to stage II patients. And certainly in this setting, one would argue that the primary treatment options certainly remain either anti–PD-1 monotherapy, either with pembrolizumab or nivolumab, based on 716 or 76K, or potentially active surveillance for the patients who are not inclined to get treated. Can you tell us a little bit about how you foresee drug development going forward in this space because, you know, for example, with HARMONY, certainly IIC disease is a part of HARMONY. We will know at least a little bit about that in this space. So what do you think about the stage IIB/C patient population? Is this a patient population in which future combinations are going to be helpful, and how would you think about where we can go forward from here? Dr. Jason Luke: It is an unfortunate circumstance that this trial could not be accrued at the pace that was necessary. I think all of us believe that the results would have been positive if they'd been able to accrue the trial. In the preliminary data set that they did disclose of that 110 patients, you know, it's clear there is a difference at a, you know, a landmark at a year. They showed a 16% difference, and that would be in line with what has been seen in stage III. And so, you know, I think it's really kind of too bad. There's really going to be no regulatory approach for this consideration. So using BRAF and MEK inhibition in stage II is not going to be part of standard practice moving into the future. To your point, though, about where will the field go? I think what we're already realizing is that in the adjuvant setting, we're really overtreating the total population. And so beyond merely staging by AJCC criteria, we need to move to biomarker selection to help inform which patients truly need the treatment. And in that regard, I don't think we've crystallized together as a field as yet, but the kinds of things that people are thinking about are the integration of molecular biomarkers like ctDNA. When it's positive, it can be very helpful, but in melanoma, we found that, unfortunately, the rates are quite low, you know, in the 10% to 15% range in the adjuvant setting. So then another consideration would be factors in the primary tumor, such as gene expression profiling or other considerations. And so I think the future of adjuvant clinical trials will be an integration of both the standard AJCC staging system as well as some kind of overlaid molecular biomarker that helps to enrich for a higher-risk population of patients because on a high level, when you abstract out, it's just clearly the case that we're rather substantially overtreating the totality of the population, especially given that in all of our adjuvant studies to date for anti–PD-1, we have not yet shown that there's an overall survival advantage. And so some are even arguing perhaps we should even reserve treatment until patients progress. I think that's a complicated subject, and standard of care at this point is to offer adjuvant therapy, but certainly a lot more to do because many patients, you know, unfortunately, still do progress and move on to metastatic disease. Dr. Diwakar Davar: Let's transition to Abstract . So we're moving on from the melanoma to the novel immunotherapy abstracts. And this is a very, very, very fascinating drug. It's . So Abstract 2508 is a phase 1 clinical update of IMA203. IMA203 is an autologous TCR-T construct targeting PRAME in patients with heavily pretreated PD-1-refractory metastatic melanoma. So Jason, in the PD-1 and CTLA-4-refractory settings, treatment options are either autologous TIL, response rate, you know, ballpark 29% to 31%, oncolytic viral therapy, RP1 with nivolumab, ORR about 30-ish percent. So new options are needed. Can you tell us a little bit about IMA203? Perhaps tell us for the audience, what is the difference between a TCR-T and traditional autologous TIL? And a little bit about this drug, IMA203, and how it distinguishes itself from the competing TIL products in the landscape. Dr. Jason Luke: I'm extremely enthusiastic about IMA203. I think that it really has transformative potential based on these results and hopefully from the phase 3 trial that's open to accrual now. So, what is IMA203? We said it's a TCR-T cell product. So what that means is that T cells are removed from a patient, and then they can be transduced through various technologies, but inserted into those T cells, we can then add a T-cell receptor that's very specific to a single antigen, and in this case, it's PRAME. So that then is contrasted quite a bit from the TIL process, which includes a surgical resection of a tumor where T cells are removed, but they're not specific necessarily to the cancer, and they're grown up in the lab and then given to the patient. They're both adoptive cell transfer products, but they're very different. One is genetically modified, and the other one is not. And so the process for generating a TCR-T cell is that patients are required to have a new biomarker that some may not be familiar with, which is HLA profiling. So the T-cell receptor requires matching to the concomitant HLA for which the peptide is bound in. And so the classic one that is used in most oncology practices is A*02:01 because approximately 48% of Caucasians have A*02:01, and the frequency of HLA in other ethnicities starts to become highly variable. But in patients who are identified to have A*02:01 genotype, we can then remove blood via leukapheresis or an apheresis product, and then insert via lentiviral transduction this T-cell receptor targeting PRAME. Patients are then brought back to the hospital where they can receive lymphodepleting chemotherapy and then receive the reinfusion of the TCR-T cells. Again, in contrast with the TIL process, however, these T cells are extremely potent, and we do not need to give high-dose interleukin-2, which is administered in the context of TIL. Given that process, we have this clinical trial in front of us now, and at ASCO, the update was from the phase 1 study, which was looking at IMA203 in an efficacy population of melanoma patients who were refractory at checkpoint blockade and actually multiple lines of therapy. So here, there were 33 patients and a response rate of approximately 50% was observed in this population of patients, notably with a duration of response approximately a year in that treatment group. And I realize that these were heavily pretreated patients who had a range of very high-risk features. And approximately half the population had uveal melanoma, which people may be aware is a generally speaking more difficult-to-treat subtype of melanoma that metastasizes to the liver, which again has been a site of resistance to cancer immunotherapy. So these results are extremely promising. To summarize them from what I said, it's easier to make TCR-T cells because we can remove blood from the patient to transduce the T cells, and we don't have to put them through surgery. We can then infuse them, and based on these results, it looks like the response rate to IMA203 is a little bit more than double what we expect from lifileucel. And then, whereas with lifileucel or TILs, we have to give high-dose IL-2, here we do not have to give high-dose IL-2. And so that's pretty promising. And a clinical trial is ongoing now called the phase 3 clinical trial, which is hoping to validate these results in a randomized global study. Dr. Diwakar Davar: Now, one thing that I wanted to go over with you, because you know this trial particularly well, is what you think of the likelihood of success, and then we'll talk a little bit about the trial design. But in your mind, do you think that this is a trial that has got a reasonable likelihood of success, maybe even a high likelihood of success? And maybe let's contextualize that to say an alternative trial, such as, for example, the TebeAM trial, which is essentially a T-cell bispecific targeting GP100. It's being compared against SOC, investigator's choice control, also in a similarly heavily pretreated patient population. Dr. Jason Luke: So both trials, I think, have a strong chance of success. They are very different kinds of agents. And so the CD3 bispecific that you referred to, tebentafusp, likely has an effect of delaying progression, which in patients with advanced disease could have a value that might manifest as overall survival. With TCR-T cells, by contrast, we see a very high response rate with some of the patients going into very durable long-term benefit. And so I do think that the SUPREME clinical trial has a... /episode/index/show/ascodaily/id/37149945

Innovations in GU Cancer Treatment at ASCO25 06/26/2025

Innovations in GU Cancer Treatment at ASCO25 Dr. Neeraj Agarwal and Dr. Jeanny Aragon-Ching discuss important advances in the treatment of prostate, bladder, and kidney cancers that were presented at the 2025 ASCO Annual Meeting. TRANSCRIPT Dr. Neeraj Agarwal: Hello, and welcome to the ASCO Daily News Podcast. I am Dr. Neeraj Agarwal, your guest host of the ASCO Daily News Podcast today. I am the director of the Genitourinary Oncology Program and a professor of medicine at the University of Utah Huntsman Cancer Institute and editor-in-chief of the ASCO Daily News. I am delighted to be joined by Dr. Jeanny Aragon-Ching, a GU medical oncologist and the clinical program director of the GU Center at the Inova Schar Cancer Institute in Virginia. Today, we will be discussing some key abstracts in GU oncology that were presented at the 2025 ASCO Annual Meeting. Our full disclosures are available in the transcript of this episode. Jeanny, it is great to have you on the podcast. Dr. Jeanny Aragon-Ching: Oh, thank you so much, Neeraj. Dr. Neeraj Agarwal: Jeanny, let's begin with some prostate cancer abstracts. Let's begin with Abstract titled, “Phase 1 study results of JNJ-78278343 (pasritamig) in metastatic castration-resistant prostate cancer.” Can you walk us through the design and the key findings of this first-in-human trial? Dr. Jeanny Aragon-Ching: Yeah, absolutely, Neeraj. So this study, presented by Dr. Capucine Baldini, introduces pasritamig, a first-in-class T-cell redirecting bispecific antibody that simultaneously binds KLK2 on prostate cancer cells and CD3 receptor complexes on T cells. KLK2 is also known as human kallikrein 2, which is selectively expressed in prostate tissue. And for reference, KLK3 is what we now know as the PSA, prostate-specific antigen, therefore making it an attractive and specific target for therapeutic engagement. Now, while this was an early, first-in-human, phase 1 study, it enrolled 174 heavily pretreated metastatic CRPC patients. So many were previously treated with ARPIs, taxanes, and radioligand therapy. So given the phase 1 nature of this study, the primary objective was to determine the safety and the RP2D, which is the recommended phase 2 dose. Secondary objectives included preliminary assessment of antitumor activity. So, pasritamig was generally well tolerated. There were no treatment-related deaths. Serious adverse events were rare. And in the RP2D safety cohort, where patients received the step-up dosing up to 300 mg of IV every 6 weeks, the most common treatment-related adverse events were low-grade infusion reactions. There was fatigue and grade 1 cytokine release syndrome, what we call CRS. And no cases of neurotoxicity, or what we call ICANS, the immune effector cell-associated neurotoxicity syndrome, reported. Importantly, the CRS occurred in just about 8.9% of patients. All were grade 1. No patients required tocilizumab or discontinued treatment due to adverse events. So, this suggests a favorable safety profile, allowing hopefully for outpatient administration without hospitalization, which will be very important when we're thinking about bispecifics moving forward. In terms of efficacy, pasritamig showed promising activity. About 42.4% of evaluable patients achieved a PSA50 response. Radiographic PFS was about 6.8 months. And among patients with measurable disease, the objective response rate was about 16.1% in those with lymph node or bone metastases, and about 3.7% in those with visceral disease, with a median duration of response of about 11.3 months. So, altogether, this data suggests that pasritamig may offer a well-tolerated and active new potential option for patients with metastatic CRPC. Again, as a reminder, with the caveat that this is still an early phase 1 study. Dr. Neeraj Agarwal: Thank you, Jeanny. These are promising results for a bispecific T-cell engager, pasritamig, in prostate cancer. I agree, the safety and durability observed here stand out, and this opens the door for further development, possibly even in earlier disease settings. So, shifting now from immunotherapy to the evolving role of genomics in prostate cancer. So let's discuss Abstract , a real-world, retrospective analysis exploring the prognostic impact of homologous recombination repair gene mutations, especially BRCA1 and BRCA2 mutations, in metastatic hormone-sensitive prostate cancer. Can you tell us more about this abstract, Jeanny? Dr. Jeanny Aragon-Ching: Sure, Neeraj. So this study was presented by Dr. David Olmos, represents one of the largest real-world analyses we have evaluating the impact of homologous recombination repair, or what we would call HRR, alterations in metastatic hormone-sensitive prostate cancer. So, this cohort included 556 men who underwent paired germline and somatic testing. Now, about 30% of patients had HRR alterations, with about 12% harboring BRCA1 or BRCA2 mutations and 16% having alterations in other HRR genes. Importantly, patients were stratified via CHAARTED disease volume, and outcomes were examined across treatment approaches, including ADT alone, doublet therapy, and triplet therapy. The prevalence of BRCA and HRR alterations were about similar between the metastatic hormone-sensitive prostate cancer and the metastatic castrate-resistant prostate cancer, with no differences observed, actually, between the patients with high volume versus low volume disease. So, the key finding was that BRCA and HRR alterations were associated with poor clinical outcomes in metastatic hormone-sensitive prostate cancer. And notably, the impact of these alterations may actually be even greater in metastatic hormone-sensitive prostate cancer than previously reported in metastatic CRPC. So, the data showed that when BRCA mutations are present, the impact of the volume of disease is actually limited. So, poor outcomes were observed across the board for both high-volume and low-volume groups. So, the analysis showed that patients with HRR alterations had significantly worse outcomes compared to patients without HRR alterations. Median radiographic progression-free survival was about 20.5 months for the HRR-altered patients versus 30.6 months for the non-HRR patients, with a hazard ratio of 1.6. Median overall survival was 39 months for HRR-altered patients compared to 55.7 months for the non-HRR patients, with a hazard ratio of 1.5. Similar significant differences were observed when BRCA-mutant patients were compared with patients harboring non-BRCA HRR mutations. Overall, poor outcomes were independent of treatment of ARPI or taxanes. Dr. Neeraj Agarwal: Thank you, Jeanny. So, these data reinforce homologous recombination repair mutations as both a predictive and prognostic biomarker, not only in the mCRPC, but also in the metastatic hormone-sensitive setting as well. It also makes a strong case for incorporating genomic testing early in the disease course and not waiting until our patients have castration-resistant disease. Dr. Jeanny Aragon-Ching: Absolutely, Neeraj. And I think this really brings home the point and the lead up to the trial, which is , a phase 3 trial that builds on this very concept of testing with a PARP inhibitor, niraparib, in the hormone-sensitive space. Can you tell us a little bit more about this abstract, Neeraj? Dr. Neeraj Agarwal: Sure. So, the AMPLITUDE trial, a phase 3 trial presented by Dr. Gerhardt Attard, enrolled 696 patients with metastatic hormone-sensitive prostate cancer and HRR gene alterations. 56% of these patients had BRCA1 and BRCA2 mutations. Patients were randomized to receive abiraterone with or without niraparib, a PARP inhibitor. The majority of patients, 78% of these patients, had high-volume metastatic hormone-sensitive prostate cancer, and 87% of these patients had de novo metastatic HSPC. And 16% of these patients received prior docetaxel, which was allowed in the clinical trial. So, with a median follow-up of nearly 31 months, radiographic progression-free survival was significantly prolonged with the niraparib plus abiraterone combination, and median was not reached in this arm, compared to abiraterone alone, which was 29.5 months, with a hazard ratio of 0.63, translating to a 37% reduction in risk of progression or death. This benefit was even more pronounced in the BRCA1 and BRCA2 subgroup, with a 48% reduction in risk of progression, with a hazard ratio of 0.52. Time to symptomatic progression also improved significantly across all patients, including patients with BRCA1, BRCA2, and HRR mutations. Although overall survival data remain immature, early trends favored the niraparib plus abiraterone combination. The safety profile was consistent with prior PARP inhibitor studies, with grade 3 or higher anemia and hypertension were more common but manageable. Treatment discontinuation due to adverse events remained low at 11%, suggesting that timely dose modifications when our patients experience grade 3 side effects may allow our patients to continue treatment without discontinuation. These findings support niraparib plus abiraterone as a potential new standard of care in our patients with metastatic hormone-sensitive prostate cancer with HRR alterations, and especially in those who had BRCA1 and BRCA2 mutations. Dr. Jeanny Aragon-Ching: Thank you, Neeraj. This trial is especially exciting because it brings PARP inhibitors earlier into the treatment paradigm. Dr. Neeraj Agarwal: Exactly. And it is exciting to see the effect of PARP inhibitors in the earlier setting. So Jeanny, now let's switch gears a bit to bladder cancer, which also saw several impactful studies. Could you tell us about Abstract , an exploratory analysis from the trial, which led to approval of enfortumab vedotin plus pembrolizumab for our patients with newly diagnosed metastatic bladder cancer? So here, the authors looked at the outcomes in patients who achieved a confirmed complete response with EV plus pembrolizumab. Dr. Jeanny Aragon-Ching: Sure, Neeraj. So, EV-302 demonstrated significant improvements in progression-free and overall survival for patients previously treated locally advanced or metastatic urothelial cancer, I'll just call it metastatic UC, as a frontline strategy, establishing EV, which is enfortumab vedotin, plus pembro, with pembrolizumab as standard of care in this setting. So, this year at ASCO, Dr Shilpa Gupta presented this exploratory responder analysis from the phase 3 EV-302 trial. Among 886 randomized patients, about 30.4% of patients, this is about 133, in the EV+P arm, and 14.5% of the patients in the chemotherapy arm, achieved a confirmed complete response. They call it the CCR rates. So for patients who achieved this, median PFS was not reached with EV+P compared to 26.9 months with chemotherapy, with a hazard ratio of 0.36, translating to a 64% reduction in the risk of progression. Overall survival was also improved. So the median OS was not reached in either arm, but the hazard ratio favored the EV+P at 0.37, translating to a 63% reduction in the risk of death. The median duration of complete response was not reached with EV+P compared to 15.2 months with chemotherapy. And among those patients who had confirmed CRs at 24 months, 78% of patients with the EV+P arm remained progression-free, and around 95% of the patients were alive, compared to 54% of patients who were progression-free and 86% alive of the patients in the chemotherapy arm. Safety among responders were also consistent with prior reports. Grade 3 or higher treatment-related adverse events occurred in 62% of EV+P responders and 72% of chemotherapy responders. Most adverse events were managed with dose modifications, and importantly, no treatment-related deaths were reported among those who were able to achieve complete response. So these findings further reinforce EV and pembro as the preferred first-line therapy for metastatic urothelial carcinoma, offering a higher likelihood of deep, durable responses with a fairly manageable safety profile. Dr. Neeraj Agarwal: Thank you for the great summary, Jeanny. These findings underscore the depth and durability of responses achievable with this combination and also suggest that achieving a response may be a surrogate for long-term benefit in patients with metastatic urothelial carcinoma. So now, let's move to Abstract , an exploratory ctDNA analysis from the trial, which evaluated perioperative durvalumab, an immune checkpoint inhibitor, in muscle-invasive bladder cancer. So what can you tell us about this abstract? Dr. Jeanny Aragon-Ching: Absolutely, Neeraj. So, in NIAGARA, presented by Dr. Tom Powles, the addition of perioperative durvalumab to neoadjuvant chemotherapy, gem/cis, significantly improved event-free survival, overall survival, and pathologic complete response in patients with cisplatin-eligible muscle-invasive bladder cancer. Recall that this led to the U.S. FDA approval of this treatment regimen on March 28, 2025. So, a planned exploratory analysis evaluated the ctDNA dynamics and their association with clinical outcomes, which was the one presented recently at ASCO. So, the study found that the incidence of finding ctDNA positivity in these patients was about 57%. Following neoadjuvant treatment, this dropped to about 22%, with ctDNA clearance being more common in the durvalumab arm, about 41%, compared to the chemotherapy control arm of 31%. Notably, 97% of patients who remained ctDNA positive prior to surgery failed to achieve a pathologic CR. So, this indicates a strong association between ctDNA persistence and lack of tumor eradication. So, postoperatively, only about 9% of patients were ctDNA positive. So, importantly, durvalumab conferred an event-free survival benefit regardless of ctDNA status at both baseline and post-surgery. Among patients who were ctDNA positive at baseline, durvalumab led to a hazard ratio of 0.73 for EFS. So, this translates to a 27% reduction in the risk of disease recurrence, progression, or death compared to the control arm. In the post-surgical ctDNA-positive group, the disease-free survival was also improved with a hazard ratio of 0.49, translating to a 51% reduction in the risk of recurrence. So, these findings underscore the prognostic value of ctDNA and suggest that durvalumab provides clinical benefit irrespective of molecular residual disease status. So, the data also supports that ctDNA is a promising biomarker for future personalized strategies in the perioperative treatment of muscle-invasive bladder cancer. Dr. Neeraj Agarwal: Thank you, Jeanny. It is great to see that durvalumab is improving outcomes in these patients regardless of ctDNA status. However, based on these data, presence of ctDNA in our patients warrants a closer follow-up with imaging studies, because these patients with positive ctDNA seem to have a higher risk of recurrence. Dr. Jeanny Aragon-Ching: I agree, Neeraj. Let's round out the bladder cancer discussion with Abstract , which reported the interim results of , which is a phase 2 study evaluating neoadjuvant sacituzumab govitecan plus pembrolizumab in cisplatin-ineligible muscle-invasive bladder cancer. Can you tell us more about this abstract, Neeraj? Dr. Neeraj Agarwal: Sure, Jeanny. So, Dr Andrea Necchi presented interim results from the SURE-02 trial. This is a phase 2 study evaluating neoadjuvant sacituzumab govitecan plus pembrolizumab, followed by a response-adapted bladder-sparing treatment and adjuvant pembrolizumab in patients with muscle-invasive bladder cancer. So, in this interim analysis, 40 patients were treated and 31 patients were evaluable for efficacy. So, the clinical complete response rate was 38.7%. All patients achieving clinical complete response underwent bladder-sparing approach with a repeat TURBT instead of radical cystectomy. Additionally, 51.6% of patients achieved excellent pathologic response with a T stage of 1 or less after neoadjuvant therapy. The treatment was well tolerated, with only 12.9% of patients experiencing grade 3 or higher adverse events without needing dose reduction of sacituzumab. Molecular profiling, interestingly, showed that clinical complete response correlated with luminal and genomically unstable subtypes, while high stromal gene expression was associated with lack of response. These results suggest that sacituzumab plus pembrolizumab combination has promising activity in this setting, and tolerability, and along with other factors may potentially allow a bladder preservation approach in a substantial number of patients down the line. Dr. Jeanny Aragon-Ching: Yeah, agree with you, Neeraj. And the findings are very provocative and support completing the full trial enrollment and further exploration of this strategy in muscle-invasive bladder cancer in order to improve and provide further bladder-sparing strategies. Dr. Neeraj Agarwal: Agree. So, let's now turn to the kidney cancer, starting with Abstract , the final overall analysis from trial, which evaluated nivolumab plus ipilimumab, so dual checkpoint inhibition strategy, versus sunitinib in our patients with metastatic clear cell renal cell carcinoma. Dr. Jeanny Aragon-Ching: Yeah, absolutely, Neeraj. So, the final 9-year analysis of the phase 3 CheckMate-214 trial confirms the long-term superiority of nivolumab and ipilimumab over sunitinib for first-line treatment of advanced metastatic renal cell carcinoma. So, this has a median follow-up of 9 years. Overall survival remains significantly improved with the combination. So, in the ITT patient population, the intention-to-treat, the hazard ratio for overall survival was 0.71. So, this translates to a 29% reduction in the risk of death. 31% of patients were alive at this 108-month follow-up compared to 20% only in those who got sunitinib. So, similar benefits were observed in the intermediate- and poor-risk groups with a hazard ratio of 0.69, and 30% versus 19% survival at 108 months. Importantly, a delayed benefit was also seen in those favorable-risk patients. So, the hazard ratio for overall survival improved from 1.45 in the initial report and now at 0.8 at 9 years follow-up, with 35% of patients alive at 108 months compared to 22% in those who got sunitinib. Progression-free survival also favored the nivo-ipi arm across all risk groups. At 96 months, the probability of remaining progression-free was about 23% compared to 9% in the sunitinib arm in the ITT patient population, 25% versus 9% in the intermediate- and poor-risk patients, and 13% compared to 11% in the favorable-risk patients. Importantly, at 96 months, 48% of patients in the nivo-ipi responders remained in response compared to just 19% in those who got sunitinib. And in the favorable-risk group, 36% of patients who responded remained in response, although data were not available for sunitinib in this subgroup. So, this data reinforces the use of nivolumab and ipilimumab as a durable and effective first-line effective strategy for standard of care across all risk groups for advanced renal cell carcinoma. Dr. Neeraj Agarwal: Thank you, Jeanny. And of course, since ipi-nivo data were presented, several other novel ICI-TKI combinations have emerged. And I'm really hoping to see very similar data with TKI-ICI combinations down the line. It is really important to note that we are not seeing any new safety signals with the ICI combinations or ICI-based therapies, which is very reassuring given the extended exposure. Dr. Jeanny Aragon-Ching: Absolutely agree with you there, Neeraj. Now, going on and moving on to Abstract , which is the trial, and they reported on the 5-year outcomes of adjuvant pembrolizumab in clear cell RCC in patients who are at high risk for recurrence. Can you tell us a little bit more about this abstract, Neeraj? Dr. Neeraj Agarwal: Sure. So, the KEYNOTE-564 trial established pembrolizumab... /episode/index/show/ascodaily/id/37136235

What Lung Cancer Abstracts Stood Out at ASCO25? 06/25/2025

What Lung Cancer Abstracts Stood Out at ASCO25? Dr. Vamsi Velcheti and Dr. Nate Pennell discuss novel treatment approaches in small cell and non-small cell lung cancer that were featured at the 2025 ASCO Annual Meeting. TRANSCRIPT Dr. Vamsi Velcheti: Hello, I'm Dr. Vamsi Velcheti, your guest host of the ASCO Daily News Podcast. I'm a professor of medicine and chief of hematology and oncology at the Mayo Clinic in Jacksonville, Florida. The 2025 ASCO Annual Meeting featured some exciting advancements in small cell lung cancer, targeted therapies for non-small cell lung cancer, and other novel [treatment] approaches. Today, I'm delighted to be joined by Dr. Nate Pennell to discuss some of the key abstracts that are advancing the lung cancer field. Dr. Pennell is the co-director of the Cleveland Clinic Lung Cancer Program and also the vice chair of clinical research at the Taussig Cancer Institute. Our full disclosures are available in the transcript of this episode. Nate, it's great to have you back on the podcast. Thanks so much for being here. Dr. Nate Pennell: Thanks, Vamsi. Always a pleasure. Dr. Vamsi Velcheti: Let's get started, and I think the first abstract that really caught my attention was Abstract , “The Randomized Trial of Relevance of Time of Day of Immunotherapy for Progression-Free and Overall Survival in Patients With Non-Small Cell Lung Cancer.” What are your thoughts about this, Nate? Dr. Nate Pennell: I agree. I thought this was one of the most discussed abstracts, certainly in the lung cancer session, but I think even outside of lung cancer, it got some discussion. So, just to put this in perspective, there have been a number of publications that have all been remarkably consistent, and not just in lung cancer but across multiple cancer types, that immunotherapy, immune checkpoint inhibitors, are commonly used. And all of them have suggested, when looking at retrospective cohorts, that patients who receive immune checkpoint inhibitors earlier in the day – so in the morning or before the early afternoon – for whatever reason, appear to have better outcomes than those who get it later in the day, and this has been repeated. And I think many people just sort of assumed that this was some sort of strange association and that there was something fundamentally different from a prognostic standpoint in people who came in in the morning to get their treatment versus those who came later in the afternoon, and that was probably the explanation. The authors of this randomized trial actually decided to test this concept. And so, about 210 patients with previously untreated advanced non-small cell lung cancer were randomly assigned to get chemo and immune checkpoint inhibitor – either pembrolizumab or sintilimab – and half of them were randomly assigned to get the treatment before 3 PM in the afternoon, and half of them were assigned to get it after 3 PM in the afternoon. And it almost completely recapitulated what was seen in the retrospective cohorts. So, the median progression-free survival in those who got earlier treatment was 13.2 months versus only 6.5 months in those who got it later in the day. So, really enormous difference with a hazard ratio of 0.43, which was statistically significant. And perhaps even more striking, the median overall survival was not reached in the early group versus 17.8 months in the late group with a hazard ratio of 0.43, also highly statistically significant. Even the response rate was 20% higher in the early patients; 75% response rate compared to 56% in the late-time-of-day patients. So very consistent across all measures of efficacy with pretty good matched characteristics across the different groups. And so, I have to tell you, I don't know what to make of this. I certainly was a skeptic about the retrospective series, but now we have a prospective randomized trial that shows essentially the same thing. So, maybe there is a difference between getting treated in the morning, although I have yet to hear someone give a very good mechanistic explanation as to why this would be. What were your thoughts on this? Dr. Vamsi Velcheti: It's indeed fascinating, Nate, and I actually think this was a very interesting abstract. Really, I was caught off guard looking at the data. I mean, if it were a drug, we would be so excited, right? I mean, with those kind of survival benefits. I don't know. I think circadian rhythm probably has something to do with it, like different cytokine profiles at the time of administration. I mean, who knows? But I think it's a randomized trial, and I think I would expect to see a mad rush for treatment appointments early in the morning given this, and at least I want my patients to come in first thing in the morning. It'll be interesting to see. Dr. Nate Pennell: It’s important to point out that in this study, everyone got chemo and immunotherapy. And, at least in our cancer center, most patients who are getting platinum-doublet chemotherapy and immunotherapy actually do get treated earlier in the day already, just because of the length of the infusion appointment that's needed. So it really is oftentimes people getting single-agent immunotherapy who are often getting the later, shorter visits. But if you have a choice, I think it would be very reasonable to have people treated earlier in the day. And I do think most of the impressions that I got from people about this is that they would like to see it reproduced but certainly well worth further investigation. And I personally would like to see more investigation into what the rationale would be for this because I still can't quite figure out, yes, if you got it at, say, you know, 5 PM, that's later in the day and I can understand that maybe your immune system is somewhat less receptive at that point than it would be in the morning. But because these checkpoint inhibitors have such long half-lives, it's still in your system the next morning when your immune system is supposedly more receptive. So I don't quite understand why that would be the case. Well, let's move on to the next study. I would like to hear your thoughts on Abstract , “Plasma-Guided, Adaptive First-Line Chemoimmunotherapy for Non-Small Cell Lung Cancer.” Dr. Vamsi Velcheti: Yeah, this was another abstract that seems to be really interesting in my opinion. I think there's kind of a lot of emphasis lately on ctDNA and MRD-based assays to monitor disease. In the lung cancer space, we haven't had a lot of clinical trials looking at this prospectively, and this was one of those pilot studies where they looked at circulating free DNA (cfDNA)-based response-adaptive strategy for frontline patients who are PD-L1 positive. So, patients started with pembrolizumab monotherapy, and based on plasma molecular response after 2 cycles, those patients without response received early treatment intensification with a platinum doublet. So the approach essentially was to reduce the chemotherapy exposure in patients who respond to immunotherapy. And only about 17.5% of the patients on the trial received chemotherapy based on lack of molecular response. So, in this trial, what they found was patients with the cfDNA response had a markedly improved PFS of 16.4 months versus 4.8 months. So essentially, like, this is a really nice study to set a foundation on which we have to do larger studies to incorporate molecular markers trying to look at cfDNA response to inform treatment strategy, either escalation or de-escalation strategies. So, I thought it was a very interesting study. Dr. Nate Pennell: Yeah. I mean, we always have this question for patients, “Should they get immunotherapy alone or combined with chemo?” and I think this certainly is intriguing, suggesting that there may be ways you can monitor people and perhaps rescue those that aren't going to respond to single agent. I'd like to see a randomized trial against, you know, this strategy, perhaps against everyone getting, say, chemoimmunotherapy or make sure that you're not potentially harming people by doing this strategy. But I agree, it's time to move beyond just observing that cell-free DNA is prognostic and important and start using it to actually guide treatment. Dr. Vamsi Velcheti: Yeah, and I would just caution though, like, you know, I think we need more data, but, however, it's certainly a very interesting piece of data to kind of help inform future trials. So, there was another abstract that caught my attention, and I think this would be a very interesting abstract in the EGFR space. Abstract , "Patritumab Deruxtecan (HER3-DXd) in Resistant EGFR-Mutant Advanced Non-Small Cell Lung Cancer Patients After Third-Generation EGFR TKI," it’s the study. What do you think about the results of this study? Dr. Nate Pennell: Yeah, this was, I would say, very widely anticipated and ultimately a little disappointing, despite being a positive trial. So, these are patients with EGFR-mutant non-small cell lung cancer who have progressed after a third-generation EGFR TKI like osimertinib. This is really an area of major unmet need. We do have drugs like amivantamab in this space, but still definitely an area where essentially patients move from having a highly effective oral therapy to being in the realm of chemotherapy as their best option. So, this HER3 antibody-drug conjugate, patritumab deruxtecan, had some good single-arm data for this. And we're sort of hoping this would become an available option for patients. This was designed against platinum-doublet chemotherapy in this setting and with a primary endpoint of progression-free survival. And it actually was positive for improved progression-free survival compared to chemo with a hazard ratio of 0.77. But when you look at the medians, you can see that the median PFS was only 5.8 versus 5.4 months. It was really a modest difference between the two arms. And on the interim analysis, it appeared that there will not be a difference in overall survival between the two arms. In fact, the hazard ratio at the interim analysis was 0.98 for the two arms. So based on this, unfortunately, the company that developed the HER3-DXd has withdrawn their application to the FDA for approval of the drug, anticipating that they probably wouldn't get past approval without that overall survival endpoint. So, unfortunately, probably not, at least for the near future, going to be a new option for these patients. Dr. Vamsi Velcheti: Yeah, I think this is a space that's clearly an unmet need, and this was a big disappointment, I should say. I think all of us were going into the meeting anticipating some change in the standard of care here. Dr. Nate Pennell: Yeah, I agree. It was something that I was telling patients, honestly, that I was expecting this to be coming, and so now, definitely a bit of a disappointment. But it happens and, hopefully, it will still find perhaps a role or other drugs with a similar target. Certainly an active area. Well, let's leave the EGFR-mutant space and move into small cell. There were a couple of very impactful studies. And one of them was Abstract , “Lurbinectedin Plus Atezolizumab as First-Line Maintenance Treatment in Patients With Extensive-Stage Small Cell Lung Cancer, Primary Results from the Phase III IMforte Trial.” So, what was your impression of this? Dr. Vamsi Velcheti: Yeah, I think this is definitely an interesting study, and small cell, I remember those days when we had barely any studies of small cell at ASCO, and now we have a lot of exciting developments in the small cell space. It's really good to see. The IMforte trial is essentially like a maintenance lurbinectedin trial with atezolizumab maintenance. And the study was a positive trial. The primary endpoint was a PFS, and the study showed improvement in both PFS and OS with the addition of lurbinectedin to atezolizumab maintenance. And definitely, it's a positive trial, met its primary endpoint, but I always am a little skeptical of adding maintenance cytotoxic therapies here in this setting. In my practice, and I'd like to hear your opinion, Nate, most patients with small cell after 4 cycles of a platinum doublet, they're kind of really beaten up. Adding more cytotoxic therapy in the maintenance space is going to be tough, I think, for a lot of patients. But also, most importantly, I think this rapidly evolving landscape for patients with small cell lung cancer with multiple new, exciting agents, actually like some FDA-approved like tarlatamab, also like a lot of these emerging therapeutics like I-DXd and other ADCs in this space. You kind of wonder, is it really optimal strategy to bring on like another cytotoxic agent right after induction chemotherapy, or do you kind of delay that? Or maybe have like a different strategy in terms of maintenance. I know that the tarlatamab maintenance trial is probably going to read out at some point too. I think it's a little challenging. The hazard ratio is also 0.73. As I said, it's a positive trial, but it's just incremental benefit of adding lurbi. And also on the trial, we need to also pay attention to the post-progression second-line treatments, number of patients who received tarlatamab or any other investigational agents. So I think it's a lot of questions still. I'm not quite sure I'd be able to embrace this completely. I think a vast majority of my patients might not be eligible anyway for cytotoxic chemotherapy maintenance right away, but yeah, it's tough. Dr. Nate Pennell: Yeah. I would call this a single and not a home run. It definitely is real. It was a real overall survival benefit. Certainly not surprising that a maintenance therapy would improve progression-free survival. We've known that for a long time in small cell, but first to really show an overall survival benefit. But I completely agree with you. I mean, many people are not going to want to continue further cytotoxics after 4 cycles of platinum-doublet chemo. So I would say, for those that are young and healthy and fly through chemo without a lot of toxicity, I think certainly something worth mentioning. The problem with small cell, of course, is that so many people get sick so quickly while on that observation period after first-line chemo that they don't make it to second-line treatment. And so, giving everyone maintenance therapy essentially ensures everyone gets that second-line treatment. But they also lose that potentially precious few months where they feel good and normal and are able to be off of treatment. So, I would say this is something where we're really going to have to kind of sit and have that shared decision-making visit with patients and decide what's meaningful to them. Dr. Vamsi Velcheti: Yeah, I agree. The next abstract that was a Late-Breaking Abstract, , “Overall Survival of Neoadjuvant Nivolumab Plus Chemotherapy in Patients With Resectable Non-Small Cell Lung Cancer in CheckMate-816.” This was a highly anticipated read-out of the OS data from 816. What did you make of this abstract? Dr. Nate Pennell: Yeah, I thought this was great. Of course, CheckMate-816 changed practice a number of years ago when it first reported out. So, this was the first of the neoadjuvant or perioperative chemoimmunotherapy studies in resectable non-small cell lung cancer. So, just to review, this was a phase 3 study for patients with what we would now consider stage II or stage IIIA resectable non-small cell lung cancer. And they received three cycles of either chemotherapy or chemotherapy plus nivolumab, and that was it. That was the whole treatment. No adjuvant treatment was given afterwards. They went to resection. And patients who received the chemoimmunotherapy had a much higher pathologic complete response rate and a much better event-free survival. And based on this, this regimen was approved and, I think, at least in the United States, widely adopted. Now, since the first presentation of CheckMate 816, there have been a number of perioperative studies that have included an adjuvant component of immunotherapy – , the study – and these also have shown improved outcomes. The KEYNOTE study with pembrolizumab also with an overall survival benefit. And I think people forgot a little bit about CheckMate-816. So, this was the 5-year overall survival final analysis. And it did show a statistically and, I think, clinically meaningful difference in overall survival with the 3 cycles of neoadjuvant chemo-nivo compared to chemo with a hazard ratio of 0.72. The 5-year overall survival of 65% in the chemo-IO group versus 55% with the chemo alone. So a meaningful improvement. And interestingly, that hazard ratio of 0.72 is very similar to what was seen in the peri-operative pembro study that included the adjuvant component. So, very much still relevant for people who think that perhaps the value of those neoadjuvant treatments might be really where most of the impact comes from this type of approach. They also gave us an update on those with pathologic complete response, showing really astronomically good outcomes. If you have a pathologic complete response, which was more than a quarter of patients, the long-term survival was just phenomenal. I mean, 95% alive at 5 years if they were in that group and suggesting that in those patients at least, the adjuvant treatment may not be all that important. So, I think this was an exciting update and still leaves very much the open question about the importance of continuing immunotherapy after surgery after the neoadjuvant component. Dr. Vamsi Velcheti: Yeah, I completely agree, Nate. I think the million-dollar question is: “Is there like a population of patients who don't have complete response but like maybe close to complete response?” So, would you like still consider stopping adjuvant IO? I probably would not be comfortable, but I think sometimes, you know, we all have patients who are like very apprehensive of continuing treatments. So, I think that we really need more studies, especially for those patients who don't achieve a complete CR. I think trying to find strategies for like de-escalation based on MRD or other risk factors. But we need more trials in that space to inform not just de-escalation, but there are some patients who don't respond at all to a neoadjuvant IO. So, there may be an opportunity for escalating adjuvant therapies. So, it is an interesting space to watch out for. Dr. Nate Pennell: No, absolutely. Moving to KRAS-mutant space, so our very common situation in patients with non-small cell lung cancer, we had the results of Abstract , “First-Line Adagrasib With Pembrolizumab in Patients With Advanced or Metastatic KRASG12C-Mutated Non-Small Cell Lung Cancer” from the phase 2 portion of the study. Why was this an interesting and important study? Dr. Vamsi Velcheti: First of all, there were attempts to kind of combine KRASG12C inhibitors in the past with immune checkpoint inhibitors, notably sotorasib with pembrolizumab. Unfortunately, those trials have led to like a lot of toxicity, with increased especially liver toxicity, which was a major issue. This is a phase 2 study of adagrasib in combination with pembrolizumab, and this is a study in the frontline setting in patients with the G12C-mutant metastatic non-small cell lung cancer. And across all the PD-L1 groups, the ORR was 44%, and the median PFS was 11 months, comparable to the previous data that we have seen with adagrasib in this setting. So it's not like a major improvement in clinical efficacy. However, I think the toxicity profile that we were seeing was slightly better than the previous trials in combination with sotorasib, but you still have a fair amount of transaminitis even in the study. At this point, this is not ready for clinical primetime. I don't think we should be using sotorasib or adagrasib in the frontline or even in the second line in combination with checkpoint inhibitors.

GI Cancer Research at ASCO25: Plenary Highlights and More 06/24/2025

GI Cancer Research at ASCO25: Plenary Highlights and More Dr. Shaalan Beg and Dr. Kristen Ciombor discuss practice-changing studies in GI cancers and other novel treatment approaches that were presented at the 2025 ASCO Annual Meeting. Transcript Dr. Shaalan Beg: Hello, I'm Dr. Shaalan Beg, welcoming you to the ASCO Daily News Podcast. I'm a medical oncologist and an adjunct associate professor at UT Southwestern Medical Center in Dallas, Texas. There were some remarkable advances in gastrointestinal cancers that were presented at the 2025 ASCO Annual Meeting, and I'm delighted to be joined by Dr. Kristen Ciombor to discuss some exciting GI data. Dr. Ciombor is the Ingram Associate Professor of Cancer Research and a co-leader of Translational Research and the Interventional Oncology Research Program at the Vanderbilt Ingram Cancer Center. Our full disclosures are available in the transcript of this episode. Dr. Ciombor, it's great to have you on the podcast today. Dr. Kristen Ciombor: Thanks, Dr Beg. It's great to be here. Dr. Shaalan Beg: Alright, let's kick it off. Big year for GI cancers. We'll start off with . This was the study sponsored by NCI and the National Clinical Trials Network (NCTN) and the Alliance group. This is a randomized study of standard chemotherapy alone or combined with atezolizumab as adjuvant therapy for stage III mismatch repair deficient colorectal cancer. Dr. Kristen Ciombor: I think this study was really definitely practice-changing, as you can tell because it was a Plenary. But I do have some concerns in terms of how we're actually going to implement this and whether this is the final answer in this disease subtype. So, as you said, the patients were enrolled with stage III resected mismatch repair deficient colon cancer, and then they were randomized to either modified FOLFOX6 with or without atezolizumab. And that's where it starts to become interesting because not many of us give FOLFOX for 6 months like was done in this study. Obviously, the study was done over many years, so that was part of that answer, but also the patients received atezolizumab for a total of 12 months. So the question, I think, that comes from this abstract is, is this practical and is this the final answer? I do think that this is practice-changing, and I will be talking to my patients with resected mismatch repair deficient colon cancer about FOLFOX plus atezolizumab. I think the big question is, do these patients need chemotherapy? And can we do a neoadjuvant approach instead? And that's where we don't have all the answers yet. Dr. Shaalan Beg: Yeah, but it has been great to see immunotherapy make its way into the adjuvant space after having made such a big impact in the metastatic space, but still some unanswered questions in terms of the need for chemotherapy and then the duration of therapy, which I guess we'll have to stay tuned in for the next couple of years to to get a lot of those questions answered. Dr. Kristen Ciombor: Yeah, but a big congratulations to the study team, to the NCTN, the NCI. I mean, this is really a great example of federally funded research that needs to continue. So, great job by the study team. The DFS 10% difference is really very large and certainly a practice-changing study. Dr. Shaalan Beg: Yeah, and and sticking with colon cancer, and and this another federally funded study, but this time funded by a Canadian cancer clinical trials group was . This is the study. It's a randomized phase 3 trial of the impact of a structured exercise program on disease-free survival for stage III or high-risk stage II colon cancer. This study got a lot of buzz, a lot of mainstream press coverage, and a lot of discussions on what that means for us for the patients who we're going to be seeing next week in our clinic. What was your takeaway? Dr. Kristen Ciombor: Yeah, this is a really interesting study, and I was so glad to see it presented because this partially answers one of the questions that patients always have for us in clinic, right? You know, once they've completed their standard chemotherapy and surgery, what else can they do to help prevent recurrence? And so we've always known and sort of extrapolated that healthy lifestyle habits are good, but now we have data, particularly in these patients. Most of them were stage III colon cancer patients, those had high-risk stage II cancer. And basically, the goal was to increase their physical activity by at least 10 MET hours per week. So, my big question, of course, as I came into this presentation was, “Okay, what does that mean exactly? How does that translate to real life?” And really what the author presented and explained was that basically most patients could hit their target by adding a 45- to 60-minute brisk walk 3 to 4 times a week. So I think this is very approachable. Now, in the confines of the study, this was a structured exercise program, so it wasn't just patients doing this on their own. But I do think kind of extrapolating from that, that this is very achievable for most patients. And not only did this prevent recurrence of their prior cancer, but actually the rate of new primary cancer diagnoses, was less, which is really interesting, especially in the breast and prostate cancer. So this was a really interesting, and I think practice-changing study as well, especially given that this is something that most patients can do. Dr. Shaalan Beg: Yeah, and there was a lot of discussion in the hallways after the presentation in terms of how this really changes our existing practice because most folks already recommend exercise as a way for improving outcomes in cancer patients. So we've already been doing that. Now we have some data on how much it can impact the benefit. But there was some discussion about what the actual degree of impact was. There was a drop-off rate in terms of how long folks were able to stick with this exercise regimen. But you've seen this in clinic when someone have their surgery, they have their chemotherapy, they've been so intimately involved with the oncology world, with the oncology practice, and they somehow feel that they're being let loose into this mean, angry world without any guidance and they're looking for something to do. “What more can I do in terms of my lifestyle?” And then here we have very solid data, as solid as can be for an intervention like exercise, showing that there is an impact and you can give a prescription for exercise when someone wraps up their chemotherapy for colon cancer, thanks to the study. Dr. Kristen Ciombor: Yeah. It was a great study. Dr. Shaalan Beg: Moving to gastroesophageal cancer, another late-breaking abstract. This is . The trial was a phase 3 trial of durvalumab plus FLOT for resectable GE junction and gastric cancer. And again, another area where immunotherapy has made an impact, and here we're seeing it move closer for earlier-stage disease. What was your take-home for the MATTERHORN trial? Dr. Kristen Ciombor: Yeah, so this looked at neoadjuvant perioperative durvalumab plus our current standard chemotherapy of FLOT versus placebo plus FLOT. And this was a large study, almost 1,000 patients were randomized. And the primary endpoint was event-free survival, and it was definitely met in favor of the D + FLOT arm, as Dr. Klempner discussed after Dr Janjigian's presentation. I do think there are still some unanswered questions here. Overall survival is not yet mature, so we do have to wait and see how that shakes out. But it's very interesting and kind of is reflective of what, as you said, we're looking at earlier and earlier lines of therapy, particularly with immunotherapy, in these GI cancer spaces. So it makes a lot of sense to test this and and to look at this. So the toxicity was pretty similar to what we would expect. Primary endpoint was met, but again, we'll have to wait and see what the survival data looks like. Dr. Shaalan Beg: Yeah, and in oncology, we know, especially for treatment that does add additional cost, it does add additional potential toxicity that we want to see that overall survival nudged. I did see some polls on social media asking folks whether their practices changed from this, and I think the results were favoring adding durvalumab for this group of patients but understanding that there are caveats to the addition of treatments and the eventual FDA approval in that indication as well. Dr. Kristen Ciombor: Exactly. I completely agree with that. Dr. Shaalan Beg: All right. How about we stick with gastroesophageal cancer? was trastuzumab deruxtecan versus ramucirumab plus paclitaxel for second-line treatment in HER2-positive unresectable or metastatic gastric cancer or GE junction cancer. This was the study. And again, antibody-drug conjugates making a big impact across different diseases. And here we have more data in the HER2-positive gastric cancer space. Your thoughts on this study? Dr. Kristen Ciombor: Yeah, so this is a really important space in gastroesophageal cancer because the HER2 positivity rate is fairly high as compared to some of our other tumor types. So, I do think one of the important things was that patients did have biopsy confirmation of HER2 status, which was very important, and then they were randomized to either T-DXd versus the kind of second-line standard of ramucirumab-paclitaxel. So this was a great practical study and really answers a question that we had for a while in terms of does anti-HER2 therapy in the second-line really impact and improve survival. So we did see a statistically significant improvement favoring T-DXd. I do think it's always important to look at toxicity, though, too. And there was about almost 14% rate of interstitial lung disease, which of course is the most feared toxicity from some of these antibody-drug conjugates, especially T-DXd. So I do think it's important to keep that in mind, but this is definitely a great addition to the armamentarium for these HER2-positive patients. Dr. Shaalan Beg: And pancreas cancer was on the stage after a very long time with a positive clinical trial. This is . These were preliminary results from a phase 2 study of elraglusib in combination with gemcitabine/nab-paclitaxel versus gemcitabine/nab-paclitaxel alone for previously untreated metastatic pancreas cancer. This is a frontline clinical trial of gemcitabine/nab-paclitaxel plus/minus the study drug. There were other cohorts in this study as well, but they reported the results of their part 3B arm. And great to see some activity in the pancreas space. And your thoughts? Dr. Kristen Ciombor: Yeah, we definitely need better treatments in pancreas cancer. This was a very welcome presentation to see. The elraglusib is an inhibitor of GSK-3beta, and it's thought that that mediates drug resistance and EMT. And so this is, I think, a perfect setting to test this drug. So patients basically were randomized. Patients with metastatic pancreas cancer were randomized 2: 1 to gemcitabine/nab-paclitaxel plus or minus this elraglusib. So, what we saw was that overall survival was better with the addition of this new drug. And overall, not only the 1-year overall survival, but also median overall survival. The thing that was interesting, though, was that we saw that the overall survival rates were 9.3 months with the combination versus 7.2 months with just gemcitabine/nab-paclitaxel. And that's a little bit lower than we've seen in other studies. So, not sure what was going on there. Was it the patients that were a bit sicker? Was it a patient selection, you know, thing? I'm not really sure how to explain that so much. Also, the toxicity profile was much higher in terms of visual impairment, with over 60% of patients being treated with the combination versus 9% with gemcitabine/nab-paclitaxel. So these were mild, grade 1 and 2, but still something to be cautious about. Dr. Shaalan Beg: And especially with this being a phase 2 trial, making sure that in a larger study we're able to better evaluate the toxicity and see if the control arm in the larger confirmatory study performs differently will be really important before this compound makes it to the clinic in our space. But very exciting to see these kinds of results for pancreas adenocarcinoma. Dr. Kristen Ciombor: Yeah. Dr. Shaalan Beg: We've talked, it seems, a couple of times on this podcast about the clinical trial. We did hear PFS and updated OS data, updated overall survival data on first-line encorafenib plus cetuximab plus modified FOLFOX6 for BRAF-mutated colorectal cancer. This was . And eagerly anticipated results – we have all previously heard the progression-free survival results – but here we heard updated overall survival results, and very well-received study it seemed from the audience that time. So what are your takeaways on the updated results for ? Dr. Kristen Ciombor: In my opinion, this was one of the most practice-confirming studies. As you mentioned, we've already seen some of the preliminary data of BREAKWATER at prior meetings. But really what was particularly impactful for me was the median overall survival with the BREAKWATER regimen. So, again, patients received FOLFOX, encorafenib cetuximab in the first line if they had BRAF-mutated V600E-mutated colorectal cancer. And the median PFS was 12.8 months, which was actually really remarkable in this traditionally very aggressive, poor prognosis subtype of tumors. So, by seeing a median overall survival of 30.3 months was just incredible, in my opinion. Just a few years ago, that was considered the median overall survival for all comers for metastatic colorectal cancer. And we know the median overall survival was more in the less than 12 months range for BRAF. So this was incredibly impactful, and I think should be absolutely practice-changing for anyone who is eligible for this regimen. I think again, where the practice meets the study is what's kind of important to think about too, how long did patients get FOLFOX, and certainly it adds toxicity to add a BRAF-targeted regimen on top of FOLFOX already. So, one of the other interesting things about the study, though, was that even though it didn't complete treatment, they actually did look at encorafenib/cetuximab alone and in the first line without chemotherapy. And those preliminary results actually looked okay, especially for patients who might not be able to tolerate chemotherapy, which we certainly see in practice. So, overall, definitely more data. And I agree that it's certainly practice-changing. Dr. Shaalan Beg: And it completely, as you mentioned, changes the outlook for a person who's diagnosed with BRAF-mutated metastatic colon cancer today versus even 7 or 8 years ago. Dr. Kristen Ciombor: And we're seeing this over and over in other subtypes too, but how you choose to treat the patient up front really matters. So really giving the right regimen up front is the key here. Dr. Shaalan Beg: And along the same lines, wanted to answer the question on whether people with MSI-high metastatic colorectal cancer need double checkpoint inhibitor therapy or is single therapy enough. So this [] study compared nivo plus ipi with nivo alone, nivo monotherapy for MSI-high metastatic colorectal cancer. And we've known that both of these are fairly active regimens, but we also know the chance of immune-related adverse events is significantly higher with combination therapy. So this was a much-needed study for this group of patients. And what were your takeaways here? Dr. Kristen Ciombor: This, of course, has been really nivo-ipi in the first-line MSI-high metastatic colorectal cancer is now a standard of care. And not everybody is eligible for it, and there could be reasons, toxicity reasons, and other things too. But as we've been seeing for the last couple of years, immunotherapy clearly beats chemo in this space. And now looking at doublet versus single immunotherapy treatment in the first line, I think really nivo-ipi does beat out monotherapy. I will say, however, there is a caveat in that we still haven't seen the nivo-ipi versus nivo in the first line. So what has been presented thus far has been across all lines of therapy, and that does muddy the waters a little bit. So definitely looking forward and and we've asked this many times and based on the statistical plan and and what not, you know, we just haven't seen that data yet. But I do think it's becoming increasingly important to consider doublet immunotherapy for these patients as long as there are no contraindications. With the again, with the caveat that we have to have these toxicity discussions in the clinic with patients because many patients can tolerate it, you know, this regimen fairly well, but there can be very severe toxicities. So, I think an informed discussion should really be had with each patient before moving forward. Dr. Shaalan Beg: Yeah, informed decision, making them aware of the potential of real significant toxicities, immune-related toxicities with double therapy. But I am curious in your practice, how often do you see people choosing doublet therapy as frontline? Dr. Kristen Ciombor: So patients are really savvy, and a lot of times they've heard this data before or have come across it in patient advocacy groups and other things, and it's really nice to be able to have that conversation of the risk versus benefit. So I will say not all of my patients choose doublet, and many of them are still cured with immunotherapy monotherapy. So the big question there is, will we ever understand who actually needs the doublet versus who can still be cured or have very good long-term outcomes with just the single agent? And that has not been answered yet. Dr. Shaalan Beg: What a great point. So the last abstract I was hoping we could talk about is or the INTERAACT2 subgroup analysis and impact of delayed retifanlimab treatment for patients with squamous cell carcinoma of the anal canal. What were your thoughts here? Dr. Kristen Ciombor: This was a study, actually we saw at ESMO, we saw the primary data at ESMO last year, and this was an update with some exploratory analyses. But this was really an important study because once again, we're looking at immunotherapy in later lines of therapy. That's how we started looking at and investigating immunotherapy, and now we're moving it up and up in the treatment course. So this was a study of carboplatin/paclitaxel plus or minus retifanlimab. Actually it was retifanlimab versus placebo. And it was a positive study, as we heard last year. This actually led to FDA approval of this regimen last month, just before ASCO, and it has now been incorporated in the NCCN guidelines as the preferred first-line option. So what I thought was important from the additional data presented at ASCO was looking at the different subgroups, it did not appear that patients with liver mets or not had different outcomes. So that was really good to see because sometimes in colon cancer we see that immunotherapy doesn't work as well when patients have liver mets. And interestingly, because we use immunotherapy in anal cancer without any biomarkers, unlike with colon cancer or some of the other tumor types, also the authors looked at PD-L1 status, and it did look like maybe patients did a little bit better if they had higher PD-L1 expression, but patients still could benefit even if they were PD-L1 negative. So that was important, I think, and we will continue to see further data come out from this study. I want to mention also that just completed accrual, so that was carbo-taxol plus or minus nivolumab. And so we should be seeing that data sometime soon, which will hopefully also confirm the ongoing role for immunotherapy in the first-line setting for anal cancer. Dr. Shaalan Beg: That was a fantastic review. Thank you, Dr Ciombor. Thanks for sharing your valuable insights with us today on the ASCO Daily News Podcast.

Breast Cancer Research Poised to Change Practice From ASCO25 06/23/2025

Breast Cancer Research Poised to Change Practice From ASCO25 Dr. Allison Zibelli and Dr. Rebecca Shatsky discuss advances in breast cancer research that were presented at the 2025 ASCO Annual Meeting, including a potential new standard of care for HER2+ breast cancer, the future of ER+ breast cancer management, and innovations in triple negative breast cancer therapy. Transcript Dr. Allison Zibelli: Hello and welcome to the ASCO Daily News Podcast. I'm Dr. Allison Zibelli, your guest host of the podcast today. I'm an associate professor of medicine and a breast medical oncologist at the Sidney Kimmel Comprehensive Cancer Center at Jefferson Health. There was a substantial amount of exciting breast cancer data presented at the 2025 ASCO Annual Meeting, and I'm delighted to be joined by Dr. Rebecca Shatsky today to discuss some of these key advancements. Dr. Shatsky is an associate professor of medicine at UC San Diego and the head of breast medical oncology at the UC San Diego Health Moores Cancer Center, where she also serves as the director of the Breast Cancer Clinical Trials Program and the Inflammatory and Triple-Negative Breast Cancer Program. Our full disclosures are available in the transcript of this episode. Dr. Shatsky, it's great to have you on the podcast today. Dr. Rebecca Shatsky: Thanks, Dr. Zibelli. It's wonderful to be here. Dr. Allison Zibelli: So, we’re starting with , which was trastuzumab deruxtecan and pertuzumab versus our more standard regimen of taxane, trastuzumab pertuzumab for first-line treatment of metastatic HER2-positive breast cancer. Could you tell us a little bit about the study? Dr. Rebecca Shatsky: Yeah, absolutely. So, this was a long-awaited study. When T-DXd, or trastuzumab deruxtecan, really hit the market, a lot of these DESTINY-Breast trials were started around the same time. Now, this was a global, randomized, phase 3 study presented by Dr. Sara Tolaney from the Dana-Farber Cancer Institute of Harvard in Boston. It was assessing essentially T-DXd in the first-line setting for metastatic HER2-positive breast cancer in addition to pertuzumab. And that was randomized against our standard-of-care regimen, which was established over a decade ago by the trial, and we've all been using that internationally for at least the past 10 years. So, this was a large , and it was one-to-one-to-one of patients getting T-DXd plus pertuzumab, T-DXd alone, or THP, which mostly is used as docetaxel and trastuzumab and pertuzumab every three weeks for six cycles. And this was in over 1,000 patients; it was 1,159 patients with metastatic HER2-positive breast cancer. This was a very interesting trial. It was looking at the use of trastuzumab deruxtecan, but patients were started on this treatment for their first-line metastatic HER2-positive breast cancer with no end date to their T-DXd. So, it was, you know, you were started on T-DXd every 3 weeks until progression. Now, CLEOPATRA is a little bit different than that, though, as we know. So, CLEOPATRA has a taxane plus trastuzumab and pertuzumab. But generally, patients drop the taxane after about six to seven cycles because, as we know, you can't be really on a taxane indefinitely. You get pretty substantial neuropathy as well as cytopenias, other things that end up happening. And so, in general, that regimen has sort of a limited time course for its chemotherapy portion, and the patients maintained after the taxane is dropped on their trastuzumab and their pertuzumab, plus or minus endocrine therapy if the investigator so desires. And the primary endpoint of the trial was progression-free survival by blinded, independent central review (BICR) in the intent-to-treat population. And then it had its other endpoints as overall survival, investigator-assessed progression-free survival, objective response rates, and duration of response, and of course, safety. As far as the results of this trial, so, I think that most of us key opinion leaders in breast oncology were expecting that this was going to be a positive trial. And it surely was. I mean, this is a really, really active drug, especially in HER2-positive disease, of course. So, the data really established that, that this is a very effective treatment in HER2-positive metastatic breast cancer. And this trial really, again, showed that. So, there were 383 patients that ended up on the trastuzumab plus deruxtecan plus pertuzumab arm, and 387 got THP, the CLEOPATRA regimen. What was really interesting also to note of this before I go on to the results was that 52% of patients on this trial had de novo metastatic disease. And that's pretty unusual for any kind of metastatic breast cancer trial. It kind of shows you, though, just how aggressive this disease is, that a lot of patients, they present with de novo metastatic disease. It's also reflecting the global nature of this trial where maybe the screening efforts are a little bit less than maybe in the United States, and more patients are presenting as later stage because to have a metastatic breast cancer trial in the United States with 52% de novo metastatic disease doesn't usually happen. But regardless, the disease characteristics were pretty well matched between the two groups. 54% of the patients were triple positive, or you could say hormone-positive because whether they were PR positive or ER positive and PR negative doesn't really matter in this disease. And so, the interim data cutoff was February of this year, of 2025. So, the follow-up so far has been about 29 months, so the data is still really immature, only 38% mature for progression-free survival interim analysis. But what we saw is that T-DXd plus pertuzumab, it really improved progression-free survival. It had a hazard ratio that was pretty phenomenal at 0.56 with a confidence interval that was pretty narrow of 0.44 to 0.71. So, very highly statistically significant data here. The progression-free survival was consistent across all subgroups. Overall survival, very much immature at this time, but of course, the trend is towards an overall survival benefit for the T-DXd group. The median durable response with T-DXd plus pertuzumab exceeded 3 years. Now, importantly, though, I want to stress this, is grade 3 or above treatment-emergent adverse events occurred in both subgroups pretty equally. But there were 2 deaths in the T-DXd group due to interstitial lung disease. And there was a 12.1% adjudicated drug-induced interstitial lung disease/pneumonitis event rate in the T-DXd group and only 1%, and it was grade 1-2, in the THP group. So, that's really the caveat of this therapy, is we know that a percentage of patients are going to get interstitial lung disease, and that some may have very serious adverse events from it. So, that's always something I keep in the back of my mind when I treat patients with T-DXd. And so, overall, the conclusions of the trial were pretty much a slam dunk. T-DXd plus pertuzumab, it had a highly statistically significant and clinically meaningful improvement in progression-free survival versus the CLEOPATRA regimen. And that was across all subgroups for first-line metastatic HER2-positive breast cancer here. And so, yeah, the data was pretty impressive. Just to go into the overall response rate, because that's always super important as well, you had 85.1% of patients having a confirmed overall RECIST response rate in the T-DXd plus pertuzumab group and a 78.6 in the CLEOPATRA group. The complete CR rate, complete response was 15.1% in the T-DXd group and 8.5 in the CLEOPATRA regimen. And it was really an effective regimen in this group, of course. Dr. Allison Zibelli: So, the investigators say at the end of their abstract that this is the new standard of care. Would you agree with that statement? Dr. Rebecca Shatsky: Yeah, that was a bold statement to make because I would say in the United States, not necessarily at the moment because the quality of life here, you have to think really hard about. Because one thing that's really important about the DESTINY-Breast09 data is that this was very much an international trial, and in many of the countries where patients enrolled on this, they were not able to access T-DXd off trial. And so, for them, this means T-DXd now or potentially never. And so, that is a really big difference whereas internationally, that may mean standard of care. However, in the US, patients have no issues accessing T-DXd in the second- or third-line settings. And right now, it's the standard of care in the second line in the United States, with all patients basically getting this second-line therapy except for some unique patients where they may be doing a PATINA trial regimen, which we saw at San Antonio Breast Cancer in 2024 of the triple-positive patients getting hormonal therapy plus palbociclib, which had a really great durable response. That was super impressive as well. Or there is the patient that the investigator can pick KADCYLA because the patient really wants to preserve their hair or maybe it's more indolent disease. But the quality of life on T-DXd indefinitely in the first-line setting is a big deal because, again, that CLEOPATRA regimen allows patients to drop their chemotherapy component about five to six months in. And with this, you're on a drug that feels very chemo-heavy indefinitely. And so, I think there's a lot more to investigate as far as what we're going to do with this data in the United States because it's a lot to commit a patient in the first-line metastatic setting. These de novo metastatic patients, some of them may be cured, honestly, on the HER2-targeting regimen. That's something we see these days. Dr. Allison Zibelli: So, very interesting trial. I'm sure we'll be talking about this for a long time. So, let's move on to , which was, I thought, a very interesting trial. This trial took patients with ER positive, advanced breast cancer after six months on an AI (aromatase inhibitor) and a CDK4/6 inhibitor. They did ctDNA every two to three months, and when they saw an ESR1 mutation emerge, they changed half of the patients to camizestrant plus CDK4/6 and kept the other half on the AI plus CDK4/6. Can you talk about that trial a little bit, please? Dr. Rebecca Shatsky: Yeah, so this was a big trial at ASCO25. This was presented as a Plenary Session. So, this was camizestrant plus a CDK4/6 inhibitor, and it could have been any of the three, so palbo, ribo, or abemaciclib in the first-line metastatic hormone-positive population, and patients were on an AI with that. They were, interestingly, tested by ctDNA at baseline to see if they had an ESR1 mutation. So, that was an interesting feature of this trial. But patients had to have already been on their CDK4/6 inhibitor plus AI for at least 6 months to enroll. And then, as you mentioned, they got ctDNA testing every 2 to 3 months. This was also a phase 3, double-blind, international trial. And I do want to highlight again, international here, because that's important when we're considering some of this data in the U.S. because it influences some of the results. So, this was presented by Dr. Nick Turner of the Royal Marsden in the UK. So, just a little bit of background for our listeners on ESR1 mutations and why they're important. This is the most common, basically, acquired resistance mutation to patients being treated with aromatase inhibitors. We know that treatment with aromatase inhibitors can induce this. It makes a conformational change in the estrogen receptor that makes the estrogen receptor constitutively active, which allows the cell to signal despite the influence of the aromatase inhibitor to decrease the estrogen production so that the ligand binding doesn't matter as much as far as the cell signaling and transcription is concerned. And camizestrant, you know, as an oral SERD, just to explain that a little bit too; these are estrogen receptor degraders. The first-in-class of a selective estrogen receptor degrader to make it to market was fulvestrant. And that's really been our standard-of-care estrogen degrader for the past 25 years, almost 25 years. And so, a lot of us are just looking for some of these oral SERDs to replace that. But regardless, they do tend to work in the ESR1-mutated population. And we know that patients on aromatase inhibitors, the estimates of patients developing an ESR1 mutation, depending on which study you look at, somewhere between 30% to 50% overall, patients will develop this mutation with hormone-positive metastatic breast cancer. There is a small percentage of patients that have these at baseline without even treatment of an aromatase inhibitor. The estimates of that are somewhere between 0.5 and up to 5%, depending on the trial you look at and the population. But regardless, there is a chance someone on their CDK4/6 inhibitor plus AI at 6 months’ time course could have had an ESR1 mutation at that time. But anyway, so they got this ctDNA every 2 to 3 months, and once they were found to develop an ESR1 mutation, the patients were then switched to the oral SERD. AstraZeneca's version of the oral SERD is camizestrant, 75 mg daily. And then their type of CDK4/6 inhibitor was maintained, so they didn't switch the brand of their CDK4/6 inhibitor, importantly. And that was looked at then for progression-free survival, but these were patients with measurable disease by RECIST version 1.1. And the data cut off here was November of 2024. This was a big trial, you know, and I think that that's influential here because this was 3,256 patients, and that's a lot of patients. So, they were all eligible. And then 315 patients ended up being randomized to switch to camizestrant upon presence of that ESR1 mutation. So, that was 157 patients. And then the other half, so they were randomized 1:1, they continued on their AI without switching to an oral SERD. That was 158 patients. They were matched pretty well. And so, their baseline characteristics, you know, the two subgroups was good. But this was highly statistically significant data. I'm not going to diminish that in any way. Your hazard ratio was 0.44. Highly statistically significant confidence intervals. And you had a median progression-free survival in those that switched to camizestrant of 16 months, and then the non-switchers was 9.2 months. So, the progression-free survival benefit there was also consistent across the subgroups. And so, you had at 12 months, the PFS rate was 60.7% for the non-treatment group and 33.4% in the treatment group. What's interesting, though, is we don't have overall survival data. This is really immature, only 12% mature as far as overall survival. And again, because this was an international trial and patients in other countries right now do not have the access to oral SERDs that the United States does, the crossover rate, they were not allowed to crossover, and so, a very few patients, when we look at progression-free survival 2 and ultimately overall survival, were able to access an oral SERD in the off-trial here and in the non-treatment group. And so, that's really important as far as we look at these results. Adverse events were pretty minimal. These are very safe drugs, camizestrant and all the other oral SERDs. They have some mild toxicities. Camizestrant is known for something weird, which is called photopsia, which is some flashing lights in the periphery of the eye, but it doesn't seem to have any serious clinical significance that we know of. It has a little bit of bradycardia, but it's otherwise really well tolerated. You know, I hate to say that because that's very subjective, right? I'm not the one taking the drug. But it doesn't have any serious adverse events that would cause discontinuation. And that's really what we saw in the trial. The discontinuation rates were really low. But overall, I mean, this was a positive trial. SERENA-6 showed that switching to camizestrant at the first sign of an ESR1 mutation on CDK4/6 inhibitor plus AI improved progression-free survival. That's all we can really say from it right now. Dr. Allison Zibelli: So, let's move on to , which was a bit more straightforward. Sacituzumab govitecan plus pembrolizumab versus chemotherapy plus pembrolizumab in PD-L1-positive, triple-negative breast cancer. Could you talk about that study? Dr. Rebecca Shatsky: Yeah, so this was also presented by the lovely Sara Tolaney from Dana-Farber. And this study made me really excited. And maybe that's because I'm a triple-negative breast cancer person. I mean, not to say that I don't treat hundreds of patients with hormone- positive, but our unmet needs in triple negative are huge because this is a disease where you have got to throw your best available therapy at it as soon as you can to improve survival because survival is so poor in this disease. The average survival with metastatic triple-negative breast cancer in the United States is still 13-18 months, and that's terrible. And so, for full disclosure, I did have this trial open at my site. I was one of the site PIs. I'm not the global PI of the study, obviously. So, what this study was was for patients who had had at least a progression-free survival of 6 months after their curative intent therapy or de novo metastatic disease. They were PD-L1 positive as assessed by the Dako 22C3 assay of greater than or equal to a CPS score of 10. So, that's what the trial was based on as well. So, standard definition of PD-L1 positive in breast cancer here. And basically, these patients were randomized 1:1 to either their sacituzumab govitecan plus pembrolizumab, day 1 they got both therapies, and then day 8 just the saci, as is standard for sacituzumab. And then the other group got the regimen. So, that is pembrolizumab with – your options are carbogem there, paclitaxel or nab-paclitaxel. And it's up to investigator's decision which upon those they decided. They followed these patients for disease progression or unacceptable toxicity. It was really an impressive trial in my opinion because we know already that this didn't just improve progression-free survival, because survival is so poor in this disease, of course, we know that it improved overall survival. It's trending towards that very much, and I think that's going to be shown immediately. And then the objective response rates were better, which is key in this disease because in the first-line setting, you've got a lot of people who, especially your relapsed TNBC that don't respond to anything. And you lose a ton of patients even in the first-line setting in this disease. And so, this was 222 patients to chemotherapy and pembro and 221 to sacituzumab plus pembro. Median follow-up has only been 14 months, so it's still super early here. Hazard ratio so far of progression-free survival is 0.65, highly statistically significant, narrow confidence intervals. And so, the median duration of response here for the saci group was 16.5 months versus 9.2 months. So, you're getting a 7-month progression-free survival benefit here, which in triple negative is pretty fantastic. I mean, this reminds me of when we saw the ASCENT data originally come out for sacituzumab, and we were all just so happy that we had this tool now that doubled progression-free and overall survival and made such a difference in this really horrible disease where patients do poorly. So, OS is technically immature here, but it's really trending very heavily towards improvement in overall survival. Importantly, the treatment-related adverse events in this, I mean, we know sacituzumab causes neutropenia, people who are experienced with this drug know how to manage it at this point. There wasn't any really unexpected treatment-related adverse events. You get some people with sacituzumab who have diarrhea. It's usually pretty manageable with some Imodium. So, it was cytopenias predominantly in this disease in this population that were highlighted as far as adverse events. But I'm going to be honest,... /episode/index/show/ascodaily/id/37046035

Precision Oncology Advances in Hematologic Cancers at ASCO25 06/20/2025

Precision Oncology Advances in Hematologic Cancers at ASCO25 Dr. John Sweetenham and Dr. Marc Braunstein highlight top research on hematologic malignancies from the 2025 ASCO Annual Meeting, including abstracts on newly diagnosed chronic phase CML, relapsed B-cell lymphoma, and multiple myeloma. Transcript Dr. John Sweetenham: Hello, and welcome to the ASCO Daily News Podcast. I'm your host, Dr. John Sweetenham. On today's episode, we'll be discussing promising advances in newly diagnosed chronic phase CML, relapsed B-cell lymphoma, multiple myeloma, and other hematologic malignancies that were presented at the 2025 ASCO Annual Meeting. Joining me for this discussion is Dr. Marc Braunstein, a hematologist and oncologist at the NYU Perlmutter Cancer Center. Our full disclosures are available in the transcript of this episode. Marc, there were some great studies in the heme space at this year's Annual Meeting, and it's great to have you back on the podcast to highlight some of these advances. Dr. Marc Braunstein: Yes, I agree, John, and thank you so much for inviting me again. It's great to be here. Dr. John Sweetenham: Let's start out with . This was a study that reported on the primary endpoint results of the phase 3B trial, which assessed asciminib versus nilotinib in newly diagnosed chronic phase CML. And the primary endpoint of this, as you know, was time to treatment discontinuation because of adverse events. Can you give us your insights into this study? Dr. Marc Braunstein: Absolutely. So, like you mentioned, you know, asciminib is an allosteric inhibitor of the BCR-ABL kinase that has activity in CML, and that includes patients with the T315I mutation that confers resistance to first- and second-generation TKIs. So, the study, which was published last year in the New England Journal of Medicine, showed superior efficacy of asciminib compared to investigator-selected first- or second-generation TKIs, actually leading to the FDA approval of asciminib in first-line CML. So, the authors of that study presented data at this year's ASCO meeting from the phase 3 ASC4START comparing safety and time to discontinuation due to adverse events of asciminib versus nilotinib, a second-generation TKI. So, 568 patients with newly diagnosed CML were randomized one-to-one to once-daily asciminib or twice-daily nilotinib. So, at a median follow-up of 9.7 months, about 11% in the asciminib group and 17% in the nilotinib group discontinued treatment, with significantly fewer discontinuations with asciminib due to adverse events. There was also a secondary endpoint of major molecular response, which was also better with asciminib. For example, the MR 4.5, which is a deep response, was 2.5% versus 0.4% favoring asciminib by week 12. So, I think in conclusion, these results build on the ASC4FIRST study, making the case for the superior safety and efficacy of asciminib versus other first- or second-generation TKIs in newly diagnosed CML. Dr. John Sweetenham: Thanks, Marc. Do you think this is going to change practice? Dr. Marc Braunstein: I think so. I think there are still some questions to be answered, such as what resistance mutations occur after first-line treatment with asciminib. But I think the sum of these studies really make the case for using asciminib upfront in CML. Dr. John Sweetenham: Okay, great. Thank you. And let's move on to our second abstract. This was and was reported from Mass General Hospital. And this was a study in patients with relapsed and refractory diffuse large B-cell lymphoma and reported the 2-year results of the so-called study. This is a comparison of glofitamab, a T-cell engaging bispecific antibody, with gemcitabine and oxaliplatin in this group of patients. Can you tell us a little bit about your impressions of this study? Dr. Marc Braunstein: Absolutely. So just for background, the treatment landscape for relapsed/refractory large B-cell lymphoma is expanding, now with two bispecific antibodies targeting CD20 that are approved after two or more lines of therapy. Among these, glofitamab was approved in 2023 based on phase 2 data showing an objective response rate of 52%, with 39% complete responses in relapsed/refractory large B-cell lymphoma patients after a median of three prior lines of therapy. Distinguishing glofitamab from epcoritamab, the other approved bispecific, glofitamab was given for 12 cycles and then stopped. Additionally, when combined with gemcitabine and oxaliplatin in the phase 3 STARGLO study, there was significantly improved overall survival compared to rituximab plus gemcitabine and oxaliplatin in transplant-ineligible relapsed/refractory large B-cell lymphoma patients at a median follow-up of 11 months. The authors of that study published last year in Lancet now present at ASCO this year the 2-year follow-up of the study. Two hundred and seventy-four patients with a median of one prior line of therapy were randomized two-to-one to glofitamab plus GemOx versus rituximab plus GemOx, with the primary endpoint of overall survival. Here, the median overall survival was not reached versus 13.5 months, with a median PFS also significantly improved at about 14 months versus 4 months in the control. CRS of note in the glofitamab arm was mostly grade 1 or 2, with only about 2.3% grade 3 events. And three of the four patients had grade 1 or 2 neurotoxicity. So, John, putting this into context, I think it's encouraging that we now have randomized data showing the superiority of a bispecific plus chemotherapy over rituximab plus chemotherapy in transplant-ineligible patients. And while only 8% of the patients in the STARGLO study had prior anti-CD19 CAR T-cell therapy, I think this regimen could be considered in those patients who are ineligible for transplant or CAR T-cell therapy. Dr. John Sweetenham: Yeah, I agree. I think a couple of other compelling numbers to me were the fact that around 55% of these patients were alive at 2 years in the group who'd received glofitamab, and that almost 90% of those having that arm of the study who had a CR at the end of treatment were alive at 12 months. So, clearly, it's an active agent and also a kind of great off-the-shelf fixed-duration alternative in these relapsed and refractory patients. Dr. Marc Braunstein: I agree, and I would also note that the phase 3 SKYGLO study is looking at glofitamab plus Pola-R-CHP versus Pola-R-CHP alone. So, we may even be using these eventually in the first-line setting. Dr. John Sweetenham: Absolutely. Let's stay on the theme of diffuse large B-cell lymphoma and look at one other abstract in that space, which was . This was a study from the HOVON group in the Netherlands, which looked at the prospective validation of end-of-treatment circulating tumor DNA in the context of a national randomized trial. What are your thoughts on this? Dr. Marc Braunstein: So, non-invasive liquid biopsies to detect and monitor cancers via circulating tumor-derived DNA or ctDNA, you know, is really emerging as a valuable tool in both solid and liquid tumors to understand disease biology, and also for drug development. So, to date, the most established application of ctDNA in lymphoma, I would say, is really for monitoring of minimal residual disease. So, in this correlative by Steven Wang and colleagues in the HOVON group, they evaluated the prognostic significance of MRD status as assessed by ctDNA following first-line treatment with curative intent with either R-CHOP or dose-adjusted R-EPOCH. At the end of treatment, encouragingly, 76% of patients were MRD-negative, and 24% were MRD-positive. Now, of note, MRD-positive status at the end of treatment predicted inferior progression-free survival at 2 years, with only 28% of patients who are MRD-positive being progression-free versus 88% who are MRD-negative. And in fact, all the patients who failed to achieve a complete response after first-line treatment and were MRD-positive ultimately relapsed. So, circulating tumor cells are rarely found in large B-cell lymphomas, and so this study really builds on accumulating data that ctDNA has clinical value to detect residual disease with a non-invasive approach. So, there are many implications of how we could potentially use this to detect early signs of relapse, to potentially escalate treatment for consolidation if patients remain MRD-positive. So, I think this will eventually become utilized in clinical practice. Dr. John Sweetenham: Yeah, I agree. I think it's interesting that it provided an independent assessment of response, which was independent, in fact, of the results of PET-CT scanning and so on, which I think was very interesting to me. And the authors of the abstract actually commented in their presentation that they think this should be integrated as part of the standard response assessment now for patients with large B-cell lymphoma. Would you agree with that? Dr. Marc Braunstein: I would. For one thing, it allows repeated sampling. It's a non-invasive approach; it doesn't necessarily require a bone marrow biopsy, and it may have more sensitivity than conventional response measures. So, I think having a standardized system to assess ctDNA will be helpful, and definitely, I think this will be a valuable biomarker of disease response. Dr. John Sweetenham: Okay, great. Thanks. We're going to change gear again now, and we're going to highlight two abstracts in the multiple myeloma space. The first one of these is . And this abstract reported on the long-term results of the study for patients with relapsed and refractory multiple myeloma. What are your comments on this presentation? Dr. Marc Braunstein: So, this study actually got a lot of press, and I've already had multiple patients asking me about CAR T-cells as a result. Just as some background, CAR T-cells targeting BCMA, which is pretty much universally expressed on malignant plasma cells in myeloma, have really shown remarkable responses, especially in heavily pretreated patients, showing superior progression-free survival in both later and earlier phases of the disease, including in randomized studies in patients with second-line or beyond. So, the was really the original Phase 1/2 study of ciltacabtagene autoleucel, one of the two approved anti-BCMA CAR T-cell products, which was investigated in patients with a median of six to seven prior lines of therapy. So, these were patients who were pretty heavily pretreated. So, in the study presented by Voorhees at this year's ASCO meeting, this was the long-term follow-up at a median of 5 years from the one-time CAR infusion in these patients with a median of five prior lines of therapy. And remarkably, of the 97 patients, 33% remained progression-free at 5 years plus, without needing any further myeloma treatment during that time. And among those 33% of patients, 23% had high-risk cytogenetics, which we know are notoriously difficult to achieve responses in. What was interesting that they presented as correlative studies was there were some biomarkers that were distinguishing the patients who had the long PFS, including enrichment of more naive T-cells in the product, lower neutrophil-to-T-cell ratio, higher hemoglobin and platelets at baseline, and higher CAR T-cell levels relative to soluble BCMA levels. And the fact that they reported a median overall survival of 61 months in these really heavily pretreated patients, I think these data are impressive. I think we're going to continue to be using CAR T even earlier in the disease status than fifth or sixth line, as it was studied in CARTITUDE-1. There are even ongoing studies looking at first-line treatment with CAR T-cells. Dr. John Sweetenham: So, do you think that those 33% of patients who are disease-free at 5 years, do you think any of those are cured? Dr. Marc Braunstein: That was one of the headlines in the press. I think if we're going to discuss things like "operational cures," where we're transforming myeloma into really a chronic disease, where patients can live practically a normal life expectancy, I think the measure of 5 years, especially in this population that was explored in CARTITUDE-1, I think we can call that close to a cure. Dr. John Sweetenham: Okay. Well, thank you. Exciting data, for sure. We're going to conclude today with another abstract in the multiple myeloma space. And this was , which looked at an MRD, minimal residual disease-driven strategy following induction and transplant-eligible newly diagnosed multiple myeloma patients and reported on the primary endpoints of the phase 3 trial. Can you walk us through this one, Marc? Dr. Marc Braunstein: Absolutely. It is a bit more complicated than the prior one we discussed because this is a randomized study with four arms. So, I'll start by saying that anti-CD38-based quadruplet regimens continue to show superior outcomes in both transplant-eligible and -ineligible newly diagnosed multiple myeloma patients. The MIDAS study mentioned is an open-label phase 3 trial with four arms in transplant-eligible newly diagnosed myeloma patients. And initially, these patients were all treated with quadruplet therapy with the anti-CD38 antibody isatuximab combined with carfilzomib, lenalidomide, and dexamethasone in 718 newly diagnosed myeloma patients. So, they received the quadruplet regimen for six cycles and then were randomized based on their MRD status at 10 to the negative fifth following six cycles of induction. And that first randomization, if they were MRD-negative, was to either consolidation with six more cycles of the quadruplet regimen or transplant, autologous transplant, plus two cycles additionally of the quadruplet regimen. And both arms were followed by lenalidomide maintenance. The primary endpoint was MRD negativity at 10 to the negative sixth prior to entering the lenalidomide maintenance component. And in addition, the patients who were MRD-positive after induction were randomized to transplant plus two cycles of consolidation or a tandem autologous transplant. So, the median follow-up of the study was about 16 months, and the pre-maintenance rate of MRD negativity was high, between 84 to 86% between the two arms who were MRD-negative, which was not significantly different. And as far as the 233 patients who were MRD-positive, the pre-maintenance MRD negativity was also not significantly different at 40% for those who received autologous transplant, and 32% who received a tandem transplant. So, there's a lot of debate in the myeloma field about the evolving role of autologous transplant and whether transplant still plays a significant role in patients who are either MRD-negative after induction or who have deep remissions and are of standard risk. So, I think these data suggest that patients who are MRD-negative after induction with a quadruplet regimen studied here, which was Isa-KRd, plus consolidation, may possibly be able to forego consolidation with autologous transplant. And likewise, for those patients who are MRD-positive after induction, tandem transplant didn't seem to provide much of a benefit compared to single transplant, which is consistent with prior studies such as the study. Dr. John Sweetenham: So, where do you think this leaves us, Marc? Are we going to need more studies before we have any definitive guidance on whether an autologous transplant is still appropriate for those patients who are MRD-negative? Dr. Marc Braunstein: Well, as clinicians, we want to do what's best for our patient. And in myeloma, the best we can do is to get as deep remissions as possible, meaning MRD negativity. And so, I think it's clear from the study and others that quadruplet regimens provide the deepest remissions when given upfront. We can debate the role of autologous transplant. I think certainly the role of tandem autologous transplant is fading. But as far as a single autologous transplant as consolidation, I think it's reasonable as a goal to try to achieve MRD negativity after the transplant, especially for patients who remain MRD-positive after induction. Dr. John Sweetenham: Okay, great. Marc, thanks as always for sharing your insights on the heme malignancies studies from the ASCO meeting this year and for joining us on the ASCO Daily News Podcast.

ASCO25 Recap: CHALLENGE, DESTINY-Breast09, and More 06/19/2025

ASCO25 Recap: CHALLENGE, DESTINY-Breast09, and More Dr. John Sweetenham and Dr. Erika Hamilton highlight key abstracts that were presented at ASCO25, including advances in breast and pancreatic cancers as well as remarkable data from the use of structured exercise programs in cancer care. Transcript Dr. Sweetenham: Hello, and welcome to the ASCO Daily News Podcast. I’m your host, Dr. John Sweetenham. Today, we’ll be discussing some of the key advances and novel approaches in cancer care that were presented at the 2025 ASCO Annual Meeting. I’m delighted to be joined again by the chair of the Meeting’s Scientific Program, Dr. Erika Hamilton. She is a medical oncologist and director of breast cancer and gynecologic cancer research at the Sarah Cannon Research Institute in Nashville, Tennessee. Our full disclosures are available in the transcript of this episode. Dr. Hamilton, congratulations on a fantastic meeting. From the practice-changing science to the world-renowned speakers at this year’s Meeting, ASCO25 really reflected the amazing progress we’re seeing in oncology today and the enormous opportunities that lie ahead of us. And thanks for coming back on to the podcast today to discuss some of these advances. Dr. Hamilton: Thanks, Dr. Sweetenham. I'm happy to join you today. It really was an impactful ASCO Annual Meeting. I probably am biased, but some great research was presented this year, and I heard lots of great conversations happening while we were there. Dr. Sweetenham: Yeah, absolutely. There was a lot of buzz, as well as a lot of media buzz around the meeting this year, and I think that’s probably a good place to start. So I’d like to dive into abstract number . This was the trial, which created a lot of buzz at the meeting and subsequently in the media. This is the study that was led by the NCI Canada Clinical Trials Group, which was the first randomized phase 3 trial in patients with stage III and high-risk stage II colon cancer, which demonstrated that a post-treatment structured exercise program is both feasible and effective in improving disease-free survival in this patient group. The study was performed over a long period of time and in many respects is quite remarkable. So, I wonder if you could give us your thoughts about this study and whether you think that this means that our futures are going to be full of structured exercise programs for those patients who may benefit. Dr. Hamilton: It’s a fantastic question. I think that this abstract did create a lot of buzz. We were very excited when we read it. It was highlighted in one of the Clinical Science Symposium sessions. But briefly, this was a phase 3 randomized trial. It was conducted at 55 centers, so really a broad experience, and patients that had resected colon cancer who completed adjuvant therapy were allowed to participate. There were essentially 2 groups: a structured exercise program, called ‘the exercise group,’ or health education materials alone, so that was called just ‘the health education group.’ And this was a 3-year intervention, so very high quality. The primary end point, as you mentioned, was disease-free survival. This actually accrued from 2009 to 2024, so quite a lift, and almost 900 patients underwent randomization to the exercise group or the health education group. And at almost 8 years of follow-up, we saw that the disease-free survival was significantly longer in the exercise group than the health education group. This was essentially 80.3% of patients were disease-free in exercise and 73.9% in the health education group. So a difference of over 6 percentage points, which, you know, at least in the breast cancer world, we make decisions about whether to do chemotherapy or not based on these kind of data. We also looked at overall survival in the exercise group and health education group, and the 8-year overall survival was 90.3% in the exercise group and 83.2% in the health education group. So this was a difference of 7.1%. Still statistically significant. I think this was really a fantastic effort over more than a decade at over 50 institutions with almost 900 patients, really done in a very systematic, high-intervention way that showed a fantastic result. Absolutely generalizable for patients with colon cancer. We have hints in other cancers that this is beneficial, and frankly, for our patients for other comorbidities, such as cardiovascular, etc., I really think that this is an abstract that deserved the press that it received. Dr. Sweetenham: Yeah, absolutely, and it is going to be very interesting, I think, over the next 2 or 3 years to see how much impact this particular study might have on programs across the country and across the world actually, in terms of what they do in this kind of adjuvant setting for structured exercise. Dr. Hamilton: Absolutely. So let’s move on to . This was an NCI-led effort comparing genomic testing using ctDNA and tissue from patients with less common cancers who were enrolled in but not eligible for a treatment arm of the trial. Tell us about your takeaways from this study. Dr. Sweetenham: Yeah, so I thought this was a really interesting study based, as you said, on NCI-MATCH. And many of the listeners will probably remember that the original NCI-MATCH study screened almost 6,000 patients to assess eligibility for those who had an actionable mutation. And it turned out that about 60% of the patients who went on to the study had less common tumors, which were defined as anything other than colon, rectum, breast, non–small cell lung cancer, or prostate cancer. And most of those patients lacked an eligible mutation of interest and so didn’t get onto a trial therapy. But with a great deal of foresight, the study group had actually collected plasma samples from these patients so that they would have the opportunity to look at circulating tumor DNA profiles with the potential being that this might be another way for testing for clinically relevant mutations in some of these less common cancer types. So initially, they tested more than 2,000 patients, and to make a somewhat complicated story short, there was a subset of five histologies with a larger representation in terms of sample size. And these were cholangiocarcinoma, small cell lung cancer, esophageal cancer, pancreatic, and salivary gland cancer. And in those particular tumors, when they compared the ctDNA sequencing with the original tumor, there was a concordance there of around 84%, 85%. And in the presentation, the investigators go on to list the specific mutated genes that were identified in each of those tumors. But I think that the other compelling part of this study from my perspective was not just that concordance, which suggests that there’s an opportunity there for the use of ctDNA instead of tumor biopsies in some of these situations, but what was also interesting was the fact that there were several clinically relevant mutations which were detected only in the circulating tumor DNA. And a couple of examples of those included IDH1 for cholangiocarcinoma, BRAF and p53 in several histologies, and microsatellite instability was most prevalent in small cell lung cancer in the ctDNA. So I think that what this demonstrates is that liquid biopsy is certainly a viable screening option for patients who are being assessed for matching for targeted therapies in clinical trials. The fact that some of these mutations were only seen in the ctDNA and not in the primary tumor specimen certainly suggests that there’s some tumor heterogeneity. But I think that for me, the most compelling part of this study was the fact that many of these mutations were only picked up in the plasma. And so, as the authors concluded, they believe that a comprehensive gene profiling with circulating tumor DNA probably should be included as a primary screening modality in future trials of targeted therapy of this type. Dr. Hamilton: Yeah, I think that that’s really interesting and mirrors a lot of data that we’ve been seeing. At least in breast cancer, you know, we still do a biopsy up front to make sure that our markers, we’re still treating the right disease that we think we are. But it really speaks to the utility of using ctDNA for serial monitoring and the emergence of mutations. Dr. Sweetenham: Absolutely. And you mentioned breast cancer, and so I’d like to dwell on that for a moment here because obviously, there was a huge amount of exciting breast cancer data presented at the meeting this year. And in particular, I’d like to ask you about , the clinical trial, which I think has the potential to establish a new first-line standard of care for metastatic HER2+ breast cancer. And that’s an area where we haven’t seen a whole lot of innovation for around a decade now. So can you give us some of the highlights of this trial and what your thinking is, having seen the results? Dr. Hamilton: Yeah, absolutely. So this was a trial in the first-line metastatic HER2 setting. So this was looking at trastuzumab deruxtecan. We certainly have had no shortage of reports around this drug, initially approved for later lines. brought it into our second-line setting for HER2+ disease and we’re now looking at DESTINY-Breast09 in first-line. So this actually was a 3-arm trial where patients were randomized 1:1:1 against standard taxane/trastuzumab/pertuzumab in one arm; trastuzumab deruxtecan with pertuzumab in another arm; and then a third arm, trastuzumab deruxtecan alone. And what we did not see reported was that trastuzumab deruxtecan-alone arm. But we did have reports from the trastuzumab deruxtecan plus pertuzumab versus the chemo/trastuzumab/pertuzumab. And what we saw was a statistically significant improvement in median progression-free survival, 26.9 months up to 40.7, so an improvement of 13.8 months, over a year in PFS. Not to mention that we’re now in the 40-month range for PFS in first-line disease. Really, across all subgroups, we really weren’t able to pick out a subset of patients that did not benefit. We did see about a 12% ILD rate with trastuzumab deruxtecan. That really is on par with what we’ve seen in other studies, around 10%-15%. I think that this is going to become a new standard of care in the first-line. I think it did leave some unanswered questions. We saw some data from the trial this past San Antonio Breast, looking at the addition of endocrine therapy with or without a CDK4/6 inhibitor, palbociclib, for those patients that also have ER+ disease, after taxane has dropped out in the first-line setting. So how we’re going to kind of merge all this together is, I suspect that there are going to be patients that we or they just don’t have the appetite to continue 3 to 4 years of trastuzumab deruxtecan. And so we’re probably going to be looking at a maintenance-type strategy for them, maybe integrating the PATINA data there. But how we really put this into practice in the first-line setting and if or when we think about de-escalating down from trastuzumab deruxtecan to antibody therapy are some lingering questions. Dr. Sweetenham: Okay, so certainly is going to influence practice, but watch this space for a little bit longer, it sounds as though that’s what you’re saying. Dr. Hamilton: Absolutely. So let’s move on to GI cancer. reported preliminary results from the randomized phase 2 study of elraglusib in combination with gemcitabine/nab-paclitaxel versus the chemo gemcitabine/nab-paclitaxel alone in patients with previously untreated metastatic pancreatic cancer. Can you tell us more about this study? Dr. Sweetenham: Yeah, absolutely. As you mentioned, elraglusib is actually a first-in-class inhibitor of GSK3-beta, which has multiple potential actions in pancreatic cancer. But the drug itself may be involved in mediating drug resistance as well as in some tumor immune response modulation. Some of that’s not clearly understood, I believe, right now. But certainly, preclinical data suggests that the drug may be effective in preclinical models and may also be effective in combination with chemotherapy and potentially with immune-modulating agents as well. So this particular , as you said, was an open-label, randomized phase 2 study in which patients with pancreatic cancer were randomized 2:1 in favor of the elraglusib plus GMP—gemcitabine and nab-paclitaxel—versus the chemotherapy alone. And upon completion of the study, which is not right now, median overall survival was the primary end point, but there are a number of other end points which I’ll talk about in just a moment. But the sample size was planned to be around 207 patients. The primary analysis included 155 patients in the combination arm versus 78 patients in the gemcitabine/nab-paclitaxel arm. Overall, the 1-year overall survival rate was 44.1% for the patients in the elraglusib-containing arm versus 23.0% in the patients receiving gemcitabine/nab-paclitaxel only. When they look at the median overall survival, it was 9.3 months for the experimental arm versus 7.2 months for chemotherapy alone. So put another way, there’s around a 37% reduction in the risk of death with the use of this combination arm. The treatment was overall well-tolerated. There were some issues with grade 1 to 2 transient visual impairment in a large proportion of the patients. The most common treatment-related adverse effects with the elraglusib/GMP combination was transient visual impairment, which affected around 60% of the patients. Most of the more serious treatment-related adverse events included neutropenia, anemia, and fatigue in 50%, 25%, and 16% of the patients, respectively. So the early results from this study show a significant benefit for 1-year overall survival and for median overall survival with, as I mentioned above, a significant reduction in the risk of death. The authors went on to mention that the median overall survival for the control arm in this study is somewhat lower than in other comparable trials, but they think that this may be related to a more advanced disease burden in this particular study. Of interest to me was that right now: there is no apparent difference in progression-free survival between the 2 arms of this study. The authors described this as potentially indicating that this may be related in some way to immune modulation and immune effects on the tumor, which, if I’m completely honest, I don’t totally understand. And so, the improvement in overall survival, as far as I can see at the moment, is not matched by an improvement in progression-free survival. So I think we probably need to wait for more time to elapse to see what happens with the study. And so, I think it certainly is an interesting study, and the results are intriguing, but I think it’s probably a little early for it to actually shift the treatment paradigm in this disease. Dr. Hamilton: Fantastic. I think we’ve been waiting for advances in pancreatic cancer for a long time, but this, not unlike others, we learn more and then learn more we don’t realize, so. Dr. Sweetenham: Right. Let’s shift gears at this point and talk about a couple of other abstracts in kind of a very different space. Let’s start out with symptom management for older adults with cancer. We know that undertreated symptoms are common among the older patient population, and reported on a randomized trial that demonstrated the effects of remote monitoring for older patients with cancer in terms of kind of symptoms and so on. Can you tell us a little bit about this study and whether you think this approach will potentially improve care for older patients? Dr. Hamilton: Yeah, I really liked this . It was conducted through the Veterans Affairs, and it was based in California, which I’m telling you that because it’s going to have a little bit of an implication later on. But essentially, adults that were 75 years or older who were Medicare Advantage beneficiaries were eligible to participate. Forty-three clinics in Southern California and Arizona, and patients were randomized either into a control group of usual clinic care alone, or an intervention group, which was usual care plus a lay health worker-led proactive telephone-based weekly symptom assessment, and this was for 12 months using the validated Edmonton Symptom Assessment System. So, there was a planned enrollment of at least 200 patients in each group. They successfully met that. And this lay health worker reviewed assessments with a physician assistant, who conducted follow-up for symptoms that changed by 2 points from a prior assessment or were rated 4 or greater. So almost a triage system to figure out who needed to be reached out to and to kind of work on symptoms. What I thought was fantastic about this was it was very representative of where it enrolled. There were actually about 50% of patients enrolled here that were Hispanic or Latinos. So some of our underserved populations and really across a wide variety of tumor types. They found that the intervention group had 53% lower odds of emergency room use, 68% lower odds of hospital use than the control group. And when they translated this to actual total cost of care, this was a savings of about $12,000 U.S. per participant and 75% lower odds of a death in an acute care facility. So I thought this was really interesting for a variety of reasons. One, certainly health care utilization and cost, but even more so, I think any of our patients would want to prevent hospitalizations and ER visits. Normally, that’s not a fantastic experience having to feel poorly enough that you’re in the emergency room or the hospital. And really showing in kind of concrete metrics that we were able to decrease this with this intervention. In terms of sustainability and scalability, I think the question is really the workforce to do this. Obviously, you know, this is going to take dedicated employees to have the ability to reach out to these patients, etc., but I think in value-based care, there’s definitely a possibility of having reimbursement and having the funds to institute a program like this. So, definitely thought-provoking, and I hope it leads to more interventions. Dr. Sweetenham: Yeah, we’ve seen, over several years now, many of these studies which have looked at remote symptom monitoring and so on in this patient population, and many of them do show benefits for that in kinds of end points, not the least in this study being hospitalization and emergency room avoidance. But I think the scalability and personnel issue is a huge one, and I do wonder at some level whether we may see some AI-based platforms coming along that could actually help with this and provide interactions with these patients outside of actual real people, or at least in combination with real people. Dr. Hamilton: Yeah, that’s a fantastic point. So let’s talk a little bit about clinical trials. So eligibility assessment for oncology clinical trials, or prescreening, really relies on manual review of unstructured clinical notes. It’s time-consuming, it’s prone to errors, and reported on the final analysis of a randomized trial that looked at the effect of human-AI teams prescreening for clinical trial eligibility versus human-only or AI-only prescreening. So give us more good news about AI. What did the study find? Dr. Sweetenham: Yeah, this is a really, a really interesting . And of course, any of us who have ever been involved in clinical trials will know that accrual is always a problem. And I think most centers have attempted, and some quite successfully managed to develop prescreening programs so that patients are screened by a health care provider or health care worker prior to being seen in the clinic, and the clinical investigator will then already know whether they’re going... /episode/index/show/ascodaily/id/37029785

Day 5: Top Takeaways From ASCO25 06/03/2025

Day 5: Top Takeaways From ASCO25 Dr. John Sweetenham shares highlights from Day 5 of the 2025 ASCO Annual Meeting, including data from large trials in advanced malignant melanoma and mCSPC plus a new approach to first-line treatment for patients with multiple myeloma who are not transplant eligible. Transcript Hello, I’m Dr. John Sweetenham, the host of the ASCO Daily News Podcast, with my takeaways on selected abstracts from Day 5 of the 2025 ASCO Annual Meeting. My disclosures are available in the transcript of this episode. The selected abstracts from this final day of ASCO25 include important new data from large, randomized trials in patients with advanced malignant melanoma and patients with metastatic castration-sensitive prostate cancer, as well as a new approach to the first-line treatment of patients with multiple myeloma who are not transplant eligible. Starting with , this study was conducted in patients with completely resected stage III or IV malignant melanoma and compared the combination of relatlimab plus nivolumab versus nivolumab alone in this population. The study, named the trial, was presented by Dr. Georgina Long from the University of Sydney, Australia. In her introduction to the study, Dr. Long explained that the current standard of care for adjuvant therapy of resected stage III/IV melanoma is with PD-1 monotherapy with nivolumab, but that about 50% of patients will suffer from a subsequent relapse. In the first-line setting in patients with advanced or unresectable melanoma, the combination of nivolumab with the LAG-3 inhibitor, relatlimab, has been previously shown to improve progression-free survival in the trial. The current study evaluated this same combination in the adjuvant setting. More than 1,000 patients from 24 countries were randomized to receive either nivolumab alone (546 patients) or the combination of nivolumab with relatlimab (547 patients). Both treatments were given for a maximum of 1 year or until progression of disease, unacceptable toxicity, withdrawal, or death. Various biomarker studies were also undertaken including LAG-3 and PD-1 expression on CD8-positive T cells. The primary endpoint of the study was relapse-free survival, and Dr. Long reported that this was the same in both arms of the study. For example, at 24 months, the relapse-free survival was 64% in the monotherapy arm compared with 62% in the combination arm. The hazard ratio was 1.01 and the P value was 0.928. Metastasis-free survival was also identical in both arms. No benefit was observed for the combination in any of the prespecified subgroups. No new toxicity signals emerged compared with the RELATIVITY-047 trial. Interestingly, the baseline surface expression of LAG-3 and co-expression of LAG-3 and PD-1 on CD8 T cells in the 098 adjuvant trial were lower than in the 047 advanced disease trial, perhaps explaining why the combination did not confer benefit over nivo alone in the adjuvant setting. This is an important result, demonstrating that results from one clinical setting cannot always be extrapolated to another. Although the combination has gained some use in the adjuvant setting, this study clearly demonstrates that more drug in this situation is no better and that monotherapy remains the current standard of care. Results from the trial for patients with metastatic castration-sensitive prostate cancer with alterations in homologous recombination repair (HRR) genes, in , were presented today by Dr. Gerhardt Attard from University College London, UK. This international, multicenter study evaluated the combination of the selective PARP inhibitor, niraparib, in combination with abiraterone acetate and prednisone. The same combination has been previously shown to improve outcomes in castration-resistant metastatic prostate cancer harboring BRCA mutations in the study. The current trial included patients with castration-sensitive disease with HRR mutations including BRCA1/2. Six hundred and ninety-six patients were randomized between niraparib, abiraterone, and prednisone plus androgen deprivation therapy, or the same combination with placebo instead of niraparib. Permitted prior therapies included no more than 6 months of prior androgen deprivation therapy and the use of docetaxel, or prior palliative radiation therapy. The primary endpoint of the study was radiographic relapse-free survival. Dr. Attard reported that the risk for radiographic progression-free survival in the whole population was significantly reduced by 37% with niraparib and abiraterone acetate plus prednisone compared with the placebo arm. The radiographic progression-free survival risk reduction with niraparib in the prespecified BRCA1/2 subgroup was 48% and reached statistical significance compared with the placebo arm. The secondary endpoint of time to symptomatic progression was also improved with niraparib in the HRR population and the BRCA1/2 subgroup. There was a trend for overall survival favoring the niraparib combination. However, the overall survival data were immature at this first interim analysis and did not yet reach statistical significance. No new safety concerns emerged with the toxicity data consistent with the MAGNITUDE study. Less than 5% more of the patients on the experimental arm discontinued treatment in comparison to the control arm. The authors conclude that the AMPLITUDE study results support the use of niraparib, abiraterone, and prednisone as a new treatment option for patients with metastatic castration- sensitive prostate cancer and BRCA and homologous recombination repair gene alterations. The results certainly support this conclusion and are potentially practice-changing. Turning to hematologic malignancies, my final selection from today’s presentations is Abstract , presented by Dr. Hang Quach from St Vincent’s Hospital, Melbourne, Australia, and describes a novel combination of elranatamab, daratumumab, and lenalidomide in patients with newly diagnosed multiple myeloma who are not transplant-eligible – the so-called . Elranatamab is a novel bispecific T-cell engaging antibody directed against BCMA and CD3, which has previously been approved for certain patients with relapsed and refractory multiple myeloma. In the present study, this was combined with lenalidomide and daratumumab in newly diagnosed patients. The report today describes the dose-finding phase of this study, which was part 1, specifically addressing so-called dose level ‘G’, comprising elranatamab 76mg subcutaneously every 4 weeks plus daratumumab 1800mg subcutaneously and lenalidomide 25mg given orally. Thirty-seven patients were entered at this dose level, of whom 32 were on treatment at the time of analysis. Early response data show an overall response rate of 97.3%. With median follow up of 7.9 months, the current CR rate is 27% with a VGPR rate of almost 68%. The most frequent toxicities were hematologic, with neutropenia observed in 75%. Some cytokine release syndrome was observed in about 60% of patients, but none was greater than grade 2. The authors conclude that this combination is active in untreated multiple myeloma, with manageable toxicity and evidence of responses which appear to deepen over time. The dose-finding component of this trial is continuing and will subsequently progress into a phase 3 trial based on the data from the current study. This will compare daratumumab plus lenalidomide with the same combination plus elranatamab in previously untreated patients. That concludes our special coverage from the 2025 ASCO Annual Meeting.

Day 4: Top Takeaways from ASCO25 06/02/2025

Day 4: Top Takeaways from ASCO25 Dr. John Sweetenham shares highlights from Day 4 of the 2025 ASCO Annual Meeting, including new research on maintenance therapy in small cell lung cancer and a virtual reality psychosocial intervention for patients undergoing hematopoietic stem cell transplantation. Transcript Hello, I’m Dr. John Sweetenham, the host of the ASCO Daily News Podcast, with my takeaways on selected abstracts from Day 4 of the 2025 ASCO Annual Meeting. My disclosures are available in the transcript of this episode. Today’s selection features reports of 3 randomized trials in very different clinical settings: maintenance therapy in extensive small cell lung cancer (SCLC), upfront surgery in advanced ovarian cancer, and a supportive care intervention for patients undergoing hematopoietic stem cell transplantation. The first of these studies, , was presented by Dr. Luis Paz-Ares from the University Hospital [October 12] in Madrid, Spain, and reports the primary results of the trial. This was a phase 3 trial evaluating the combination of lurbinectedin and atezolizumab as first-line maintenance therapy in patients with extensive small cell lung cancer. Despite some improvements in the first-line treatment of extensive small cell lung cancer with the use of checkpoint inhibitors in combination with platinum-based chemotherapy, most of the patients experience early disease progression and long-term survival remains very limited. This provides a rationale for considering a maintenance intervention. Lurbinectedin is an alkylating agent and transcription inhibitor [that is] already approved in the United States for patients with relapsed/refractory metastatic SCLC following platinum-based chemotherapy. It has been shown to synergize with immune checkpoint inhibitors in pre-clinical studies and has also been evaluated in early-phase clinical trials. The trial is a global, randomized trial in which patients are initially treated with atezolizumab, and those patients who do not progress on induction therapy are then randomized to maintenance therapy with atezolizumab alone or atezolizumab with lurbinectedin. The primary endpoints of the study were progression-free and overall survival. Four hundred and eighty-three patients were randomized and at a median follow-up of 15 months, the median progression-free survival for patients who received the combination was 5.4 months and the median overall survival was 13.2 months. This compares with 2.1 and 10.6 months, respectively, in patients who received atezolizumab only. The lurbinectedin and atezolizumab combination was generally well-tolerated, with no new or unexpected safety signals. The benefit was consistent in magnitude across all the relevant patient subgroups. This is the first phase 3 study to show a progression-free and overall survivial improvement with first-line maintenance in extensive stage SCLC and the result is likely to be practice-changing, establishing a new standard of care in this tough-to-treat disease. Next up is , presented by Dr. Sven Mahner from LMU University in Munich, Germany. This describes the results of the study, a randomized trial of upfront surgical therapy in advanced ovarian cancer. As background, total macroscopic tumor resection with maximal effort cytoreductive surgery is the cornerstone of treatment in patients with advanced ovarian cancer. The optimal timing of such surgery remains controversial, whether it’s more beneficial as a primary cytoreductive surgery before chemotherapy or in the form of interval cytoreductive surgery after 3 cycles of neoadjuvant chemotherapy. Previous studies have addressed this issue, but results have been confounded by issues of patient and center selection. The study is a randomized, international, multicenter phase 3 trial that compares the outcomes of the timing of surgery in surgically fit patients with seemingly resectable FIGO stage IIIB/IVB ovarian, tubal, and peritoneal carcinoma. To ensure consistent and adequate surgical quality, participating centers in the trial were required to obtain accreditation and undergo an onsite quality assurance review. This included assessment of infrastructure, surgical proficiency, complete resection rates, and surgical volume. Seven hundred and ninety-seven patients with advanced ovarian cancer were randomized to undergo surgery prior to therapy with 6 cycles of carboplatin and paclitaxel along with bevacizumab and a PARP inhibitor, or to have the surgery between the third and fourth cycle of the same systemic therapy. Of the initial 797 patients, 688 comprised the intent-to-treat population, of whom 345 received primary cytoreductive surgery and 343 received neoadjuvant chemotherapy followed by interval cytoreductive surgery. The results show that patients undergoing primary surgery had significantly improved progression-free survival compared with those who had interval cytoreductive surgery (median progression-free survival was 22.1 months versus 19.7 months). No difference in overall survival was observed between the 2 arms of the study. This is the first study to show a benefit for primary cytoreductive surgery, although the progression-free survival improvement was not reflected in an overall survival difference. A subgroup analysis for patients who underwent complete cytoreduction suggests a progression-free survival and survival benefit, although it isn’t clear to me that the study was powered for this endpoint. Nevertheless, these are very difficult studies to perform, and the investigators should be congratulated for this robustly conducted clinical trial. Today’s final abstract is , presented by Dr. Hermioni Amonoo from Harvard Medical School. The trial evaluated BMT-VR, a virtual reality psychosocial intervention for patients undergoing bone marrow transplantation. This randomized trial included adult patients undergoing autologous and allogeneic transplantation. The BMT-VR platform included, among others, modules addressing psychoeducation, coping, acceptance, and gratitude. BMT-VR patients were provided with VR headsets and completed all modules during their hospitalization. Patient-reported outcomes were then assessed at 2, 4, 12, and 24 weeks post-BMT. Use of the VR tool was tracked during hospitalization. Control patients received usual care during their hospital stay and were then assessed at the same intervals post-BMT. Eighty evaluable patients were randomized, 39 to BMT-VR and 41 to usual care. Completion rates for the BMT-VR modules were high [at] around 70-75%. Patients who received the BMT-VR intervention experienced significantly improved anxiety, quality of life, and coping at 4 weeks post-BMT. In the longer term, sustained benefits were seen at 24 weeks for some endpoints including quality of life, with some benefits, including for depression and PTSD symptoms, improving longitudinally over the study period. These data are preliminary and will need to be confirmed in larger multicenter studies, but this trial demonstrates the feasibility of using virtual interventions in our patients and also provides intriguing preliminary data that they may be effective.

Day 3: Top Takeaways From ASCO25 06/01/2025

Day 3: Top Takeaways From ASCO25 Dr. John Sweetenham shares highlights from Day 3 of the 2025 ASCO Annual Meeting, including new research for the treatment of advanced renal cell carcinoma and 2 studies on novel approaches in non-small cell lung cancer. Transcript Dr. John Sweetenham: Hello, I’m Dr. John Sweetenham, the host of the ASCO Daily News Podcast, with my takeaways on selected abstracts from Day 3 of the 2025 ASCO Annual Meeting. Today’s selection features studies addressing the treatment of advanced renal cell carcinoma and 2 studies exploring novel approaches in non-small cell lung cancer. My disclosures are available in the transcript of this episode. The first abstract is number . This study, led by Dr. Toni Choueiri of the Dana-Farber Cancer Institute, describes the final analysis of the CheckMate 214 trial, which compared the combination of nivolumab and ipilimumab with sunitinib for the first-line treatment of advanced renal cell carcinoma. The ipi-nivo combination is approved for the frontline treatment of intermediate and poor-risk advanced renal cell carcinoma based on the primary analysis of the CheckMate 214 trial, which demonstrated a higher response rate and longer overall survival compared with sunitinib. Today’s presentation provided the final safety and efficacy results for the trial with long-term follow-up of more than 9 years. The intent-to-treat (ITT) population in this trial comprised 550 patients randomized to nivo and ipi versus 546 who received sunitinib. The final analysis showed sustained long-term benefit for the combination therapy. Patients given nivolumab plus ipi had a 29% reduction in the risk for death compared with sunitinib. For patients with intermediate or poor-risk disease, there was a 31% reduction in the risk of death. The probability of remaining in response through 8 years was more than doubled with nivolumab plus ipilimumab versus sunitinib in the ITT population at 48% versus 19%, and in the intermediate and poor-risk population at 50% versus 23%. The other important observation is that patients with favorable-risk disease appeared to have a 20% reduction in the risk for death at 9 years and more durable responses. This suggests a possible delayed benefit for ipi and nivo in this group since these differences were not seen in the earlier analysis. No new safety signals emerged with longer follow-up, and the results confirm the use of ipi and nivo as a standard front-line combination therapy in this disease. Since this combination has been in widespread use for some years, the results are not surprising although the subgroup analysis suggesting benefit in favorable-risk patients is likely to inform practice in the future. Today’s second abstract is number is , which was presented by Dr. Tony Mok from the Chinese University of Hong Kong, describing results from the phase 3 trial. This trial compared the antibody-drug conjugate patritumab deruxtecan with platinum-based chemotherapy in patients with EGFR-mutated advanced non-small cell lung cancer following a third-generation tyrosine kinase inhibitor (TKI). Patritumab deruxtecan, also known as HER3-DXd, comprises a fully human anti-HER3 IgG3 monoclonal antibody conjugated to a topoisomerase 1 inhibitor payload, and showed activity in a previous phase 2 trial in patients relapsing after EGFR TKI and chemotherapy. In this phase 3 study, this agent was compared with platinum-based chemotherapy in eligible patients with an EGFR-activating mutation who had previously received 1 or 2 EGFR TKIs, at least one of which was a third-generation drug, with relapse or progression after this therapy. Five hundred and eighty-six patients were enrolled, with progression-free survival as the primary endpoint. The primary analysis showed a 9-month progression-free survival of 29% for the experimental arm compared with 19% for platinum-based chemotherapy, for a hazard ratio of 0.77 and a P value of 0.011. With higher progression-free survival rates at 6 months and 12 months, HER3-DXd also had a better objective response rate (35.2% versus 25.3%) compared with platinum-based chemotherapy (PBC), and HER3-DXd also extended intracranial progression-free survival compared with PBC in patients with brain metastases, with a hazard ratio of 0.75. Grade 3 or more treatment-related adverse events occurred in 73% of patients treated with HER3-DXd and 57% of patients who received PBC. HER3-DXd had a higher rate of grade or more 3 thrombocytopenia, and drug-related interstitial lung disease occurred in 5% of patients in the HER3-DXd arm. The follow-up will need more time to mature since no overall survival data are currently available, but definitely an agent to watch with interest. Moving on to today’s final abstract, , was presented by Dr. Pasi Jänne from the Dana-Farber Cancer Institute, describing results from the phase 2 portion of the KRYSTAL-7 study. This study is exploring the use of a potent KRAS inhibitor, adagrasib, in combination with pembrolizumab in patients with advanced or metastatic KRASG12C- mutated non-small cell lung cancer. Adagrasib has already received accelerated approval in the U.S. for previously treated locally advanced or metastatic NSCLC with a KRASG12C mutation. A previous report from the study demonstrated encouraging activity in combination with pembrolizumab in the frontline setting for this patient group who also had more than 50% expression of PD-L1. The presentation today described efficacy and safety data for this drug combination across all PD-L1 expression levels. One hundred and forty-nine patients with a median age of 67 years were treated with the combination, 104 of whom had PD-L1 expression level results available, representing the so-called biomarker population in this trial. The overall response rate for the entire study population was 44%. In the biomarker population, the overall response rate ranged from 36% in those with less than 1% PD-L1 expression to 61% for those with more than 50% expression. For all patients, the median response duration was just over 26 months, and the median progression-free and overall survival rates were 11 and 18.3 months respectively. For the biomarker population, the median progression-free and overall survival were highest in those patients with more than 50% PD-L1. No new safety issues emerged from this analysis; the most frequent toxicities were nausea, diarrhea, and increases in transaminases. Immune-related toxicities included pneumonitis, hypothyroidism, and hepatitis. These are important results and the results of the phase 3 portion of KRYSTAL-7, which compares first-line therapy with adagrasib plus pembro versus pembro alone in the KRASG12C mutated/PD-L1 more than 50% group, will be informative. For those patients with lower levels of PD-L1 expression, the authors suggest that the treatment escalation may be beneficial, possibly including the addition of chemotherapy. That concludes today’s report. Thanks for listening and I hope you will join me again tomorrow to hear more top takeaways from ASCO25.

Day 2: Top Takeaways From ASCO25 05/31/2025

Day 2: Top Takeaways From ASCO25 Dr. John Sweetenham shares highlights from Day 2 of the 2025 ASCO Annual Meeting, including new data on the treatment of ER+/HER2-negative breast cancer and potentially practice-changing results for patients with cutaneous squamous cell carcinoma at high risk of recurrence.  Transcript Dr. John Sweetenham: Hello, I’m Dr. John Sweetenham, your host of the ASCO Daily News Podcast, welcoming you to our special coverage of the 2025 ASCO Annual Meeting. Today, I’ll be bringing you my takeaways on selected abstracts from Day 2 of the Meeting. My disclosures are available in the transcript of this episode. Today’s selection features important, new data on the treatment of ER-positive, HER2-negative breast cancer, the use of tumor treating fields in combination with chemotherapy for locally advanced pancreatic cancer, and potentially practice-changing results for patients with cutaneous squamous cell carcinoma at high-risk of recurrence. Our first selected abstract is . This important phase 3 study was presented by Dr. Erika Hamilton from the Sarah Cannon Research Institute in Nashville and evaluated the use of a novel agent, vepdegestrant, in patients with ER-positive/HER2-negative breast cancer, which had progressed after first-line endocrine therapy. Vepdegestrant is a selective oral PROTAC estrogen receptor degrader, which targets wild-type and mutant estrogen receptor through a novel mechanism of action which directly harnesses the ubiquitin-proteasome system to degrade ER. It has potential advantages over fulvestrant, a selective ER degrader which has to be administered intramuscularly and has limited benefit in patients who progress after endocrine therapy plus a CDK4/6 inhibitor. Building on the encouraging results from the initial phase 1/2 study of vepdegestrant, Dr. Hamilton reported results from the global phase 3 trial, comparing this agent with fulvestrant. The patients in the study had already received treatment with hormone therapy and a CDK inhibitor and were randomly assigned to receive treatment with either vepdegestrant (313 patients) or fulvestrant (311 patients). The vepdegestrant was taken orally each day, while the fulvestrant was given intramuscularly on days 1 and 15 of the first cycle of treatment and day 1 of each subsequent treatment cycle. Patients were stratified by the presence of wild-type ER or ESR1 mutation. A total of 43.3% of patients had ESR1 mutations; 136 of those were in the vepdegestrant group and 134 in the fulvestrant group. For patients with ESR1 mutations, vepdegestrant significantly increased progression-free survival compared with fulvestrant. For patients who received vepdegestrant, the median PFS was 5 months versus 2.1 months for those who received fulvestrant. The clinical benefit rate was 42.1% in the vepdegestrant group vs. 20.2% in the fulvestrant group. The overall response rate was 18.6% in the vepdegestrant group compared with only 4% in the fulvestrant group. The PFS and response benefits of vepdegestrant were largely restricted to the population with ESR1 mutations. Overall survival data are currently immature. The safety profile was favorable, with fewer than 5% of patients having dose reductions or discontinuation due to toxicity. The most frequent toxicities were fatigue, nausea, and elevated transaminases. The authors concluded that oral vepdegestrant demonstrates statistically significant and clinically meaningful improvement in progression-free survival compared with fulvestrant in this group of patients with ESR1-mutated ER+/HER2- advanced breast cancer who have progressed after endocrine therapy and a CDK inhibitor. Patients with recurrent disease in this context are now routinely tested for ESR1 mutations, and this agent is for sure a potential treatment option for them. The next study on today’s episode, , reports on the use of tumor treatment fields for patients with locally advanced pancreatic cancer. Tumor treatment fields are electric fields which disrupt cell division and may also induce an enhanced immune response, using a non-invasive portable device attached to the skin, and are already approved for the treatment of some cancers, including GBM and non-small cell lung cancer. A previous phase 2 trial, , confirmed the feasibility and safety of using this approach in combination with gemcitabine plus or minus nabpaclitaxel in pancreatic cancer. In today’s presentation, Dr. Vincent Picozzi from the Virginia Mason Medical Center in Seattle presented the results of the trial, a phase 3 study comparing gemcitabine and nabpaclitaxel with the same chemotherapy plus tumor treatment fields in patients with locally advanced pancreatic adenocarcinoma. Five hundred and seventy-one eligible patients were enrolled in the study with a total of 405 (198 in the treatment field group and 207 in the standard arm) comprising the modified intent- to-treat population. The duration of chemotherapy treatment was comparable in both study arms, and patients receiving treatment fields had a median exposure of almost 27 weeks. Statistically significant improvements were observed for several study endpoints, including overall survival (a median of 16.2 versus 14.2 months), distant PFS (at 13.9 versus 11.5 months) and pain-free survival (at 15.2 versus 9.1 months), all in favor of the treatment fields arm. Although quality of life data were not reported in detail, the authors noted a significant improvement in global health status in the treatment fields arm. Safety data showed a higher level of skin adverse events in the treatment fields arm but were otherwise as expected for the GnP combination. These are quite remarkable results which add to the growing evidence base for tumor treatment fields and are particularly compelling in this patient group given the substantial improvement in pain-free survival. It will be especially interesting to see the mature analysis of the quality-of-life endpoints in a subsequent report. The final selection today is , which describes the C-POST trial, a phase 3 trial of adjuvant cemiplimab versus placebo in patients with high-risk cutaneous squamous cell carcinoma of the skin. This study was presented by Dr. Danny Rischin from the Peter MacCallum Cancer Centre in Melbourne, Australia. Although surgical resection with or without adjuvant radiation is curative in 90% of patients with cutaneous squamous cell carcinoma, high-risk features, including nodal disease, skin and subcutaneous metastases, perineural invasion and bone involvement, predict for an inferior prognosis. Cemiplimab, a PD-1 targeting antibody is standard therapy for patients with locally advanced or metastatic disease who are not candidates for curative surgical resection or radiation therapy, with an overall response rate of almost 50%. The study evaluated the use of cemiplimab as adjuvant therapy following surgery and radiation in high-risk patients, compared with placebo. Treatment was administered at 3-week intervals for 12 weeks, and then 6-week intervals for a further 36 weeks, with a primary endpoint of disease-free survival. Four hundred and fifteen patients were randomized in the study, 209 to cemiplimab and 206 to placebo. With median follow-up at 24 months, Dr. Rischin reported a highly significant improvement in disease-free survival for the cemiplimab arm, 49.4 months for placebo versus not reached for cemiplimab, with improvements also observed in the rates of locoregional recurrence and distant recurrence at 80% and 60% reductions, respectively. No new safety signals were observed. This study is potentially practice-changing and provides strong evidence that cemiplimab should be considered the new standard of care in this clinical context.
