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

Dr. 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.
