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 ECOG 1599 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 FLAURA 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 FLAURA2 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 MARIPOSA 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 CHRYSALIS 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 PALOMA 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 ELIOS 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.

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 KEYNOTE-B15 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 EV-302 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 EV-303 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 EV-304 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 NIAGARA, 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 SWOG S1602. 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 KEYNOTE-905, 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, LITESPARK-011, which looked at lenvatinib and belzutifan versus cabozantinib in the advanced setting, and then we have an adjuvant study, LITESPARK-022, 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 PEACE-3 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.

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 phase 3 data 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 trial 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 cause a lot of pain, functional deficits, really impacts quality of life as well. So developing novel therapies, many of which are currently in clinical trials and many of which are currently continuing to be developed, remains so critical. How do we develop better systemic therapies, better targeted therapies, better biomarkers for recurrent metastatic head neck cancer to improve their survival and quality of life and functional outcomes. Those are the two big areas that require the most work at this time within the head and neck cancer field. Dr. Monty Pal: That's brilliant. I mean, I have to tell you I could probably talk to you all day about this, such a fascinating topic. It's a very exciting time in the field. Thank you, Dr. Rosenberg, for all your incredible contributions and thanks for sharing with us your insights on the ASCO Daily News Podcast. Dr. Ari Rosenberg: Yeah, and thanks for the introduction.

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 PLANeT 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 D-ToRCH 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 KEYNOTE-522 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 publication 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 study 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.

Dr. Monty Pal and Dr. Mary Feng discuss the latest advances in metastatic colorectal, gastric, and gastroesophageal cancers that were presented at the 2026 ASCO Gastrointestinal Cancers Symposium.

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 DESTINY-Breast03 and DESTINY-Breast02. 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 CLEOPATRA 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 DESTINY-Breast09, 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 HER2CLIMB-05, 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 PATINA, 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 DESTINY-Breast05 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 KATHERINE, 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 Trop-2 ADC. 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, ASCENT-04. That showed that SG with a checkpoint inhibitor was superior, so pembrolizumab was superior to the standard KEYNOTE-355 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, TROPION-Breast02, that was 10 percent of the patients who had PD-L1-positive disease but didn't get a checkpoint inhibitor, and for the ASCENT-03 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 the pressure of treatment in about 40 percent of patients. And it doesn't happen when you first walk in the door. And what we've seen is that oral SERDs as single agents are better than standard single-agent endocrine therapy in that setting. The problem that we've had with that approach is that we're now really interested in giving targeted agents with our endocrine therapies, not just in the first-line setting where CDK4/6 inhibitors are our standard of care with survival benefit for ribociclib and, you know, survival benefit in subsets with other CDK4/6 inhibitors, and abemaciclib with a numeric improvement. So we give it first line. The question is, what do you do in the second-line setting? Because of the recent data, we now believe that oral SERDs should be really given with a targeted agent. And some datasets which were recently presented, which I think have helped us with that, have been EMBER-3 and then the most recently evERA BC, or evERA Breast Cancer, that looked at the oral SERD giredestrant with everolimus compared to standard of care endocrine therapy with everolimus, where 100 percent of patients received prior CDK4/6 inhibitor and showed a marked improvement in progression-free survival, including in the subsets of patients with a short response, 6-12 months of prior response to CDK4/6 inhibitor and in those who had a PIK3CA pathway mutation. The thing is that the benefit looks like it's much bigger in the ESR1 mutant population, although response was better, PFS wasn't better in the wild type. So, we're still trying to figure that out. We also saw EMBER-3 with imlunestrant and abemaciclib as a second line. Not everybody had had a prior CDK4/6 inhibitor; they compared it to imlunestrant alone, but still the data was quite striking and seemed to cross the need for ESR1 mutations. And then lastly, we saw data from the single arms of the ELEVATE trial looking at elacestrant with everolimus and abemaciclib and showed these really marked progression-free survival data, even though single-arm, that crossed the mutation status. At least for the everolimus combination, abemaciclib analysis is still to come in the mutated subgroups. But really remarkable PFS, much longer.  Single-agent fulvestrant after CDK4/6 inhibitor AI has a PFS in like the three-month range and in some studies, maybe close to five months. These are all at 10-plus months and really looking very good. And so those questions are, is it ESR1 mutation alone? Is it all comers? We'd like all comers, right? We believe in the combination approach and we're learning more about combinations with drugs like capivasertib and other drugs as we move forward. Everybody now wants to combine their targeted agent with an oral SERD because they're clearly here to stay with quite remarkable data. The other issue, so the second issue in the metastatic setting is, does it make a difference if we change to an oral SERD before radiographic imaging evidence of progression? And that was the question asked in the SERENA-6 trial where patients had serial monitoring for the presence of ESR1 mutations in ctDNA. And those who had them without progression on imaging could be randomized to switch to camizestrant with the same CDK4/6 inhibitor or stay on their same AI CDK4/6 inhibitor. And they showed a difference in progression-free survival that markedly favored camizestrant. But interestingly, the people who were on the standard control arm had an ESR1 mutation, we think AIs don't work, they stayed on for nine more months. The patients who were on the camizestrant stayed on for more than 16 months. And they presented some additional subset data which showed the same thing: follow-up PFS data, PFS2, all beneficial in SERENA-6 at the San Antonio [Breast Cancer Symposium]. So, we're still a little bit unclear about that. They did quality of life, and pain was markedly improved. They had a marked delayed time to progression of pain in the camizestrant arm. So this is all a work in progress, trying to understand who should we switch without progression to an oral SERD based on this development of this mutation that correlates with resistance. And, you know, it's interesting because the median time to having a mutation was 18 months and the median time to switch was almost 24 months. And then there were like more than 3,000 patients who hadn't gotten a mutation, hadn't switched, and were still okay. So screening everybody is the big question, and when you would start and who you would change on and how this affects outcome. Patients didn't have access to camizestrant in the control arm, something we can't fix but we have experimental drugs. We're actually planning a trial, I hope in collaboration with the French group Unicancer, and looking at this exact question. You know, if you switch and you change the CDK4/6 inhibitor and then you also allow crossover, what will we see? Dr. Monty Pal: We're coming right to the tail end of our time here, and I could probably go on for another couple of hours with you here. But if you could just give us maybe one or two big highlights from San Antonio, any thoughts to leave our audience with here based on this recent meeting? Dr. Hope Rugo: Yeah, I mean, I talked about a lot of those new data already from San Antonio, and the one that I'd really like to mention which I think was, you know, there were a lot of great presentations including personalized screening presented from the WISDOM trial by my colleague Laura Esserman, fascinating and really a big advance. But lidERA was the big highlight, I think, outside of the HER2CLIMB-05 which I talked about earlier in HER2-positive disease. And this study looked at giredestrant, the oral SERD versus standard of care endocrine therapy as treatment for medium and high-risk early-stage breast cancer. And what they showed, which I think was really remarkable with just about a three-year median follow-up, was an improvement in invasive disease-free survival with a hazard ratio of 0.7. I mean, really quite remarkable and so early. It looked as though this was all driven by the high-risk group, which makes sense, not the medium risk, it's too early. And also that there was a bigger benefit in patients who were on tamoxifen compared to giredestrant versus AI, but for both groups, the confidence intervals didn't cross 1. There's even a trend towards overall survival, even though it's way too early. I think that, you know, really well-tolerated oral drug that could improve outcome in early-stage disease, this is the first advance we've seen in over two decades in the treatment of early-stage hormone receptor-positive disease with just endocrine therapy. I think we think that we don't want to give up CDK4/6 inhibitors because we saw a survival benefit with abemaciclib and a trend with giving ribociclib in the NATALEE trial. So we're thinking that maybe one approach would be to give CDK4/6 inhibitors and then switch to an oral SERD or to have enough data to be able to give oral SERDs with these CDK4/6 inhibitors for early-stage disease. And that's all in the works, you know, lots of studies going on. We're going to see a lot of data with both switching 8,000 patients with an imlunestrant switching trial, an elacestrant trial going on, and safety data with giredestrant with abemaciclib and soon to come ribociclib. So, this is going to change everything for the treatment of early-stage breast cancer, and I hope cure more patients of the most common subset of the most common cancer diagnosed in women worldwide. Dr. Monty Pal: Super exciting. It's just remarkable to hear how this has evolved since 25 years ago, which is really the last time I sort of dabbled in breast cancer.  Thank you so much, Hope, for joining us today.

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 ASCO ACT Network 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 ACT Network. 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 like that analogy a lot. Let's get into the weeds for a second. What would that proposal to Congress look like? What are we trying to put in front of them to help alleviate the drug shortages? Dr. Jason Westin: We could spend a couple hours, and I know podcasts usually are not set up to do that. And so I won't go through every part. I will direct you that there have been a couple of recent publications from ASCO specifically detailing solutions, and there was a recent white paper from the Senate Finance Committee that went through some legislative solutions being explored. So Dr. Gralow, ASCO CMO, and I recently had a publication in JCO OP detailing some solutions, more in that white paper from the Senate Finance. And then there's a working group actually going through ASCO's Health Policy Committee putting together a more detailed proposal that will be published probably around the end of 2026. Very briefly, what needs to happen is for government contracts for purchasing these drugs, there needs to be an outlay for quality, meaning that if you have a manufacturing facility that is able to deliver product on time, reliably, you get a bonus in terms of your contract. And that changes the model to prioritize the quality component of manufacturing. Without that, there's no reason to invest in maintaining your machine or upgrading the technology you have in your manufacturing plant. And so you have bottlenecks emerge because these drugs are cheap, and there's not a profit margin. So you get one factory that makes this key drug, and if that factory hasn't had an upgrade in their machines in 20 years, and that machine conks out and it takes 6 months to repair or replacement, that is an opportunity for that drug to go into shortage and causes a mad dash for big hospitals to purchase the drug that's available, leaving disparities to get amplified. It's a nightmare when those things happen, and they happen all the time. There are usually dozens, if not hundreds, of drugs in shortage at any given time. And this has been going on for decades. This is something that we do need large, system-wide fixes and that investment in quality, I think, will be a key part. Dr. Monty Pal: Yeah, brilliantly said. And I'll make sure that we actually include those articles on the tagline for this podcast as well. I'll talk to our producer about that as well.  I'm really glad you mentioned the time in your last comment there because I felt like we just started, but in fact, I think we're right at our close here, Jason, unfortunately. So, I could have gone on for a couple more hours with you. I really want to thank you for these absolutely terrific insights and thank you for all your advocacy on behalf of ASCO and oncologists at large. Dr. Jason Westin: Thank you so much for having me. I have enjoyed it. Dr. Monty Pal: Thanks a lot. And many thanks to our listeners too. You can find more information about ASCO's advocacy agenda and activities at asco.org.

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 TRUST 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 TRUST 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 EORTC and CHORUS, which I think we've talked about. The two more modern ones are SCORPION and JCOG0602. 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 Moore: Unless they were on trial. But I mean, I think we will have to see. 600 patients, I would bet a lot of them missed the ADC wave. So, I do not know that we can say we know what drove these phenomenal – these are some of the best curves we've seen outside of BRCA. And then coming back to your point about the BRCA population here, that is a really critical question that I do not know that we're ever going to answer. There have been hypotheses around a tumor that is driven by BRCA, if you surgically cytoreduced it, and then chemically cytoreduced it with chemo, and so you're starting PARP with nothing visible and likely still homogeneous clones. Is that the group we cured? And then if you give chemo first before surgery, it allows more rapid development of heterogeneity and more clonal evolution that those are patients who are less likely to be cured, even if they do get cytoreduced to nothing at interval with use of PARP inhibitor in the front line. That is a question that many have brought up as something we would like to understand better. Like, if you are BRCA, should you always just go for it or not? I do not know that we're ever going to really get to that. We are trying to look at some of the other studies and just see if you got neoadjuvant and you had BRCA, was anyone cured? I think that is a question on SOLO1 I would like to know the answer to, and I don't yet, that may help us get to that. But that's sort of something we do think about. You should have a fair number of them in TRUST. It wasn't a stratification factor, as I remember. Dr. Linda Duska: No, it wasn't. They stratified by center, age, and ECOG status Dr. Kathleen Moore: So you would hope with randomization that you would have an equal number in each arm. And they may be able to pull that out and do a very exploratory look. But I would be interested to see just completely hypothesis-generating what this looks like for the patients with BRCA, and I hope that they will present that. I know they're busy at work. They have translational work. They have a lot pending with TRUST. It's an incredibly rich resource that I think is going to teach us a lot, and I am excited to see what they do next. Dr. Linda Duska: So, outside of TRUST, we are out of time. I just want to give you a moment if there were any other messages that you want to share with our listeners before we wrap up. Dr. Kathleen Moore: It's an exciting time to be in GYN oncology. For so long, it was just chemo, and then the PARP inhibitors nudged us along quite a bit. We did move more patients, I believe, to the cure fraction. When we ultimately see OS, I think we'll be able to say that definitively, and that is exciting. But, you know, that is the minority of our patients. And while HRD positive benefits tremendously from PARP, I am not as sure we've moved as many to the cure fraction. Time will tell. But 50% of our patients have these tumors that are less HRD. They have a worse prognosis. I think we can say that and recur more quickly. And so the advent of these antibody-drug conjugates, and we could name 20 of them in development in GYN right now, targeting tumor-associated antigens because we're not really driven by mutations other than BRCA. We do not have a lot of things to come after. We're not lung cancer. We are not breast cancer. But we do have a lot of proteins on the surface of our cancers, and we are finally able to leverage that with some very active regimens. And we're in the early phases, I would say, of really understanding how best to use those, how best to position them, and which one to select for whom in a setting where there is going to be obvious overlap of the targets. So we're going to be really working this problem. It is a good problem. A lot of drugs that work pretty well. How do you individualize for a patient, the patient in front of you with three different markers? How do you optimize it? Where do you put them to really prolong survival? And then we finally have cell surface. We saw at ASCO, CDK2 come into play here for the first time, we've got a cell cycle inhibitor. We've been working on WEE1 and ATR for a long time. CDK2s may hit. Response rates were respectable in a resistant population that was cyclin E overexpressing. We've been working on that biomarker for a long time with a toxicity profile that was surprisingly clean, which I like to see for our patients. So that is a different platform. I think we have got bispecifics on the rise. So there is a pipeline of things behind the ADCs, which is important because we need more than one thing, that makes me feel like in the future, I am probably not going to be using doxil ever for platinum-resistant disease. So, I am going to be excited to retire some of those things. We will say, "Remember when we used to use doxil for platinum-resistant disease?" Dr. Linda Duska: I will be retired by then, but thanks for that thought. Dr. Kathleen Moore: I will remind you. Dr. Linda Duska: You are right. It is such an incredibly exciting time to be taking care of ovarian cancer patients with all the opportunities.  And I want to thank you for sharing your valuable insights with us on this podcast today and for your great work to advance care for patients with GYN cancers.

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)] Community of Practice. 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 Community of Practice. 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 CAR-T [cell therapy guideline], and I would be remiss not to point out that actually ASCO has a, I am a little biased, but a wonderful guideline on irAE 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 ASCO, SITC, ESMO 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.

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 Put into Practice podcast. 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 (Abstract 94). 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' Abstract 93 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, Abstract 102, 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 Abstract 97. 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 Abstract 550 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. And thanks to our listeners too. You are going to find links to all the abstracts that we discussed today in the transcript of this episode.
