RCUS - NYSE

Good afternoon, thank you for attending today's Arcus Biosciences Third Quarter 2024 Earnings Call. My name is Tamiya and I will be your moderator for today's call. All lines will be muted during the presentation portion of the call, with an opportunity for questions and answers at the end. [Operator Instructions] I would now like to pass the conference over to your host, Pia Eaves, Vice President of Investor Relations. You may proceed.

Hello, everyone, and thank you for joining us on today's conference call to discuss Arcus' third quarter 2024 financial results and pipeline updates, including our upcoming presentation of [Indiscernible]. I'd like to remind you that on this call management will make forward looking statements, including statements about our cash runway and our expected clinical development milestones and timelines. All statements, other than historical facts, reflect the current beliefs and expectations of management and involve risks and uncertainties that may cause our actual results to differ from those expressed. Those risks and uncertainties are described in our most recent quarterly report on Form 10-Q that has been filed with the SEC. Today, you'll hear from our CEO, Terry Rosen; CMO, Dimitry Nuyten, COO, Jennifer Jarrett; and CFO, Bob Goeltz. We'll also be joined by our President Juan Jaen for questions after the prepared remarks. With that, I'll turn the call over to Terry.

Thank you very much Pia and thank you all for joining us today. As we head in into 2025, our highest priority is to launch our late stage development program for our HIF-2 alpha inhibitor Casdatifan. As you know, just two weeks ago we presented initial data from our ARC-20 study evaluating cas in late-line clear-cell RCC in an oral plenary session at the ENA meeting. These data clearly validate our conviction that cas will be a best-in-class HIF-2 alpha inhibitor demonstrating improvement in every key efficacy measure that we analyze versus belzutifan. As you know, belzutifan is the only HIF-2 alpha inhibitor on the market today. So let's go to slide five and I'll recap the highlights from our data set. First off, the rate of primary progression in the 100 milligram daily expansion cohort was only 19% and it was similarly low in the 50 milligram daily expansion cohort. In fact, the rate of primary progression for the combined 60 patients in the 50mg and 100mg expansion cohorts was approximately half of what was observed in LITESPARK-005. Keep in mind that the primary progression rate and disease control rate DCR are the only data points that are fully mature and will not change, so this is really a huge difference for the molecule. Second, we reported a 34% ORR and 25% confirmed ORR for the 100 milligram cohort with two to three unconfirmed responses pending confirmation and also multiple stable disease patients still on therapy. As of the data cutoff, every responder across both cohorts remained on treatment with the exception of that one patient whose response did not confirm. The belzutifan data actually provide good precedent for the kinetics of response with HIF-2-alpha inhibition, so this is important. Approximately 60% of responses occurred within six months of treatment and an additional 20% occurring occurred in each of the ensuing six month periods, so that goes out to 18 months. These data illustrate why our ORR could in reality more likely should further improve across both cohorts. Keep in mind those follow up times are 8 months and 11 months respectively for 50 and 100 milligrams. The ARC-20 data also demonstrated that the activity of cats is extremely durable. As of the data cutoff a median PFS had not been reached even with that 11 months median follow up. Recall that belzutifan was approved based upon its PFS of 5.6 months and our median PFS which we expect to report in early 2025 should easily exceed that benchmark. Given that PFS is the registrational endpoint, this will be another important source differentiation. Our Spider Plots show multiple patients either past or approaching the 52-week duration of treatment and you also see deepening responses with time. I want to emphasize that these data were generated in a heavily pre-treated patient population relative to that of LITESPARK-005. Specifically, approximately 25% of the patients enrolled in ARC-20 wouldn't eligible for LITESPARK-005. For the 50 milligram cohort, despite only 8 months median follow up at the data cutoff, we reported a 14% primary progression rate, a 25% ORR and just over 21% confirmed ORR with the one unconfirmed responder pending confirmation and a very impressive almost remarkable DCR of 86%. One of the confirmed responders was a complete response. Beyond the responders, and again another important point, nearly 40% of patients still continued on therapy with stable disease, including a few whom are extremely close already to the 30% response threshold and you can see that in the spider plots. While this data set is still evolving and will continue to improve, we now have two different cohorts that are demonstrating clear efficacy differentiation relative to that of belzutifan and there's a lot more data to come. On slide 6 we show the data that we expect to share from ARC-20 throughout 2025. We plan to present additional data from the 100 milligram and 50 milligram cohorts of ARC-20, including more mature ORR and median PFS that will be early next year. Later in the year, we plan to present initial data from the 150 milligram and the 100 milligram once daily tablet expansion cohorts, so that's another 60 patients worth of data. We also plan to present initial safety data from our cas plus cabo combination cohort. To date, the safety data from this cohort, which we already shared with the FDA as part of our pre-phase 3 meeting, are consistent with the profiles of the individual drugs and the dose intensity of 100mg of cas and 60mg of cabo has been maintained. Given the importance of the ARC-20 data, and that's important to us, it's important to you, it's important to investigators, the ongoing evolution of the datasets and the multiple cohorts that we've enrolled, we're considering additional opportunities to provide updates from this study in the more near term. We remain full steam ahead towards the initiation of our first Phase 3 study PEAK-1. The investigator enthusiasm for the study is incredibly high, which we believe will support rapid enrollment. Now let me switch gears to Domvanalimab, our Fc-silent anti-TIGIT antibody. Just yesterday the SITC abstract was released with data from part one of our ARC-10 study which evaluated domvanalimab that's our anti PD1 antibody versus zim versus chemotherapy and first line PD-L-1 high non-small cell lung cancer. As a reminder, we terminated the study for strategic reasons to focus on STAR-121, our chemo combination study. But the early termination gave us both an opportunity to generate and now present a data set from a study that was conducted under phase 3 conditions. On slide 27 we summarized the abstract. We showed that dom + zim exceeded zim monotherapy on ORR PFS and OS. For both PFS and OS, we achieved the hazard ratio below 0.65, which is far better than the threshold considered clinically meaningful in the setting, with median PFS of 11.5 months and median OS not reached for dom zim, these results are meaningfully above contemporary benchmark studies for anti PD-1 monotherapy. Dimitri is going to discuss these data in detail, but I want to make two important points. First off, these data reaffirm the growing recognition that Fc-silent anti-TIGIT antibodies have a differentiated safety profile relative to that of Fc enabled antibodies. There are only two Fc-silent anti-TIGIT antibodies in late stage clinical development today, Dom and Astra

Thanks, Terry. Starting with PEAK-1, our first phase 3 trial for cas and clear cell RCC. We expect to begin this study in the first half of next year. The design is shown on slide 23 of our deck. The study will enroll approximately 700 patients and will compare CAF plus cabozantinib to cabo monotherapy and IGO [ph] experienced clear cell RCC. Cabo is the standard of care in this setting, so clinicians are extremely comfortable administering cabo and adjusting its dosing to optimize both cabo's efficacy and safety. We believe that the vast majority of the second line patient population, approximately 80% will be eligible for PEAK-1 given this study only excludes patients who received prior treatment with cabo in the first line setting. You can see on slide 24 that this study targets an approximately 11,000 patient population in the U.S. assuming a treatment time in excess of 15 months. This is a $2 billion plus market opportunity in the G7 countries alone. We were also excited to move into the IO naive setting with our collaboration with Astra

Thanks, Jen. Our abstract for ARC-10 was released yesterday morning and data will be presented in a late breaker poster session this Friday at SITC. ARC-10 was originally a global phase 3 study evaluating dom and zim versus sim versus chemotherapy in patients with PD-L1 high non-small cell lung cancer. This is important since the trial conducts with the same rigorous as would be expected from a registrational phase 3. Though ARC-10 was discontinued for strategic reasons, we continue to follow patients and now with over two years of median follow up, we are presenting our first overall survival data for dom and zim in any setting. As you will see, the results are supportive of dom's ability to meaningfully extend survival in patients. Starting with the design on slide 30, the trial was randomized 2 to 2 to 1, so there were 38 patients in the dom and zim arm, 40 patients in the sim monotherapy arm and 17 patients in the chemotherapy arm. Baseline characteristics were generally well balanced across the arms, with some prognostic imbalances favoring the chemotherapy arm. The data cutoff for this analysis was May 17, 2024 and the median follow up was 24.5 months. On slide 31 we show the Kaplan‑Meier curve for overall survival. These results are quite impressive. In fact, even with two years of median follow up, a median OS has not been reached for dom and zim. The Hazard ratio for overall survival was 0.64, a result that is very clinically meaningful. Additionally, the sim control arm performed right in line with the benchmark studies of pembrolizumab in the setting with a median overall survival of 24.4 months. When compared to chemotherapy, sim demonstrated a hazard ratio of 0.63 for overall survival. Again, this is right in line with KEYNOTE 42 and other benchmark studies. The poster presentation will also highlight additional data including progression free survival and overall response rates, which also showed a clear benefit for dormant sim over sim and put sim performance in line with the benchmark studies for pembrolizumab. The safety profile was also consistent with prior observations for dom and

Thanks Dimitri. Our cash as of the end of the third quarter was $1.1 billion as compared to $1 billion as of the end of the second quarter. Our cash position was bolstered by a $100 million collaboration continuation payment from Gilead. Turning to our P&L, we recognized GAAP revenue for the third quarter of $48 million, which compares to $39 million for the second quarter of this year. Our revenue is primarily driven by collaborations with Gilead and Taiho and in the third quarter included $15 million resulting from the Taiho opt-in for Quemli in July. We continue to expect to recognize GAAP revenue of approximately $30 million for the fourth quarter of 2024. Our R&D expenses for the third quarter stated net of reimbursements from Gilead and were $123 million as compared to $115 million in the second quarter of this year. We continue to expect modest increases in R&D expenses for the fourth quarter 2024. G&A expenses were $30 million for the third quarter and were flat compared to the second quarter of this year. We expect G&A expenses to remain stable for the fourth quarter. Finally, we expect our cash and investments balance at the end of 2024 to be between $950 million and $985 million as compared to our prior guidance of $885 million to $925 million. We expect these resources to fund operations into mid-2027. Our guidance excludes additional potential opt in payments and milestones from our partners. For more details regarding our financial results, please refer to our earnings press release from earlier today in our 10-Q. I'll now turn it back to Terry for concluding remarks.

So thank you all again for joining us this afternoon. As I mentioned earlier on the call, we have a lot coming and that starts with our Citi presentation for dom zim on Friday, followed by additional presentations from ARC-20 and the initiation of our first phase 3 study for cas over the coming months. As we head into 2025, we'll be approaching our first phase 3 data set for STAR-221 and first line gastric cancer. We appreciate your interest and support of Arcus and I'll now open the call for questions.

Thank you. [Operator Instructions] The first comes from Yigal Nochomovitz with Citi. You may proceed.

Hi Terry and team. Thanks for taking the question. I'm getting a lot of interest in cas and people are asking about the potential for Gilead's opt in. Can you provide any more color there as far as whether they're specified windows? Obviously you mentioned that you need a qualifying data package. Does that mean, could be the monotherapy or Gilead interested in seeing some of the combo data with Volru or the initial combo data with cas plus cabo coming up soon. That's the first question. Thanks.

Yes, so we have aligned with Gilead on what data is needed for the qualifying data package. We're very close to and meeting that data requirement. So we will be delivering a package to them relatively soon. And as we've been saying, we expect a decision to be made either late this year or early next year.

Okay, thank you. And then I'm just curious, was there any preclinical work done with Volru and cas to sort of just do a quick validation of the -- the combo safety in NHPS or something before going into this collaboration with A

No, there was no preclinical work done. It was very typical sort of situation where you have two molecules, well defined profiles that we simply taking in to do those studies initially in human.

Okay. And then last one is, I'm curious about Etrumadenant. Obviously you had the data I believe at ASCO for the ARC-9. What are you thinking there in terms of the later development? There is the other cohort, which is the second line. Cohort. Cohort-A. Is that what you're waiting for before you decide with a registrational study, given the obviously very, very strong OS that you saw in the third line?

No, to be honest, it's just a matter of us moving. So we're extremely excited about the data set and we're just working through with Gilead. You can see obviously we're starting a number of later stage trials and we still have the full portfolio going. So we're working through what our next steps will be and we'll share them once they're defined together with Gilead.

Okay, thank you, Terry.

Thanks, Yigal. Appreciate it.

Thank you. The next question comes from Lee Watsik [ph] with Cantor Fitzgerald. You may proceed.

Hey guys, thank you very much for taking my questions. I guess, Juan, in the IO naive renal cell cancer setting. I understand A

Yes, so I'll comment there. We've agreed with Astra

Okay, understood. And I know you mentioned on the call, it sounds like you're looking to optimize the step plan for the phase 3 non-small cell lung for dom. Can you expand a little bit on that? What does that entail?

Yes, so my comment was more general than that. We make that point for all of our studies that were continuously looking at the stat plans for all of our programs. Obviously in the anti-TIGIT field, there's been changes made by others. There's been some comments or statements put forward from the ODAC with the FDA. So at this point we're not making any changes, but we just wanted to acknowledge that we're always considering that possibility.

Okay, got it. And maybe just the last question. I wonder if you can talk a little bit about the clinical benefits that you are seeing for stable disease patients from the cas study. And it seems like you got a decent number of them still on study. So I guess how clinically relevant is disease control for these patients?

Yes, so this Dimitri. I'll take the question. So it's very, very relevant for patients. Just imagine. Resist was determined based on large data sets, mostly for chemotherapy. There had been an effort to standardize assessments of treatment and based on reproducibility interobserver variability, a threshold of 30% was set. I think everybody would agree whether or not you're at 25% or 35% depending on the tumor volume that is not really relevant. Having tumor that doesn't grow and that has gone down in tumor volume is very important. And then the other point that is more, let's say from a regulatory perspective, response rate is never ever a registrational endpoint beyond accelerated approval. In this case in kidney cancer, progression free survival is the relevant endpoint and everybody who does not progress contributes to that. And in a Kapler Meier estimate, the longer you are free of progression, meaning the longer your response is lasting or the longer your stable disease is lasting, contributes equally for each patient to the Kaplan Meier estimate for progressive free survival. So both from a clinical perspective for patients and from a regulatory registrational perspective, they're very important. And from a registrational perspective it is equally important as a response.

Thank you.

We'd like to be able to get to everybody, so if you have more than a couple of questions, can you please hop off and join the queue at a later point? That would be great. Thank you.

Thank you. Our next question comes from Jonathan Miller with Evercore ISI. You may proceed.

Hi guys. Thanks for taking my question and reminding us to limit our questions just before I got my chance in the queue. Appreciate that. Can I start with some questions about HIF-2 please? I noticed in your prepared remarks you talk about two unconfirmed PRs that could still confirm. I'd really like to get some detailed color on that. We hear reports there have been papers written that suggest that one of, maybe I think one of those two, based on how I'm counting, had a subsequent scan of stable disease. So can you comment of those two unconfirmed partial responses that you're talking about, how many of those have not had a follow up scan yet or might be expected to confirm based on one additional follow up scan? And maybe building off of that, given that a lot of the differentiation you're talking about compared to belzutifan is in the PD rate, that is at the first scan here, how well early in the curves, how well do you anticipate that to translate to a better profile versus belzutifan in a combo setting, especially combos with drugs like TKIs which give their benefits rapidly at those first couple scans.

The first question, kind of teasing. There's a lot of different questions in there, but maybe just to jump to the back part of your question as far as who has not had a follow up scan yet that was a responder. There was one patient in the 100 big cohort that had not had a follow up scan yet and one patient in the 50 mig cohort. So their last scans show them as being responders for the first time and they are waiting for their confirmatory scans now. And then, as we said for the 100 mig, there is one patient that did not confirm. So far, only one patient. And in fact, as we mentioned in the script, out of all of the responders, every responder is still on treatment with the exception of one patient that did not have a confirmed response in the hydromed cohort. Did that answer your question and we can go to the...

Yes, I was thinking specifically of that 100 mig cohort. I'm just trying to count UPRs and try to get a sense for where the ORR could realistically get to at the end of the day. And in that 100mg cohort specifically.

Yes, so, 33 point plus percent was the ORR. We said that one patient will not confirm. So that means the maximum confirmed ORR that we can get to based on the current responders. So that's excluding stable disease patients that have also seen significant tumor reduction. So there could be other stable disease patients that also contribute to the ORR. But based on the current responders, the maximum confirmed response rate we can get to is 31%. And then if just one of those pending responders confirms, then that would take the ORR to 28.3%.

Great guy. And on.

Yes, I can take the second, the second part of the question about stable disease in the combination. So a few things. So of course in the combination we are going against carbo and we're building up on top of carbo. So everybody in the control arm would get carbo and we are doing the combination. If you think what the combination can do, it can actually help patients in different ways. On cas we see both early responders, we have more than a few patients responding at the first scan at six weeks. We've also disclosed two patients now that responded respectively at 12 and 14 months. So that's something that goes on top of the TKI response rate. The primary progression response rate for carboxanthenib [ph] is about 20% or a little bit less. And we hope to catch more patients from that 20% with a different mechanism for the combination. So of course we can't speculate what it would be. Let's say we would expect it to also improve on top of a TKI.

Sure, I guess. But I'm asking specifically about the comparison to the other F2 here to belzutifan. If your differentiation from them is in PD rate, or at least a lot of it is in PD rate, how well do you be able to? Would you be able to observe that differentiation in a combo setting where, you have the TKI to pick up the slack on the first scan a little bit?

So I'll comment there. I mean, again, you're purely speculating, but as you know, greater than 90% of those patients have some sort of HIF-2 driven component. And so there's absolutely still room to reduce the rate of primary progression. It puts more people into the queue, if you will. And I think that the place where you'll see that number of patients then leads into every other efficacy measure, whether it's ORR, PFS. And I have to say, there's no reason to not start to think about why you may not see advantages in OS, even though that's not the approvable endpoint at this stage. There's nothing intrinsic about clear cell RCC that should suggest that you couldn't start to prolong OS as well.

Thank you.

Thanks, Jon.

Thank you. The next question comes from Peter Lawson with Barclays. You may proceed.

Great, thank you. Just a couple of follow ups on the opt-in. Kind of what drives that decision for Gilead between this year and next year? Is it something from your side, their side, or is there a different data cut? And then if Gilead doesn't obtain, what are the next steps?

So I'll take that. First of all, there's nothing specifically driving it other than, how long they take to make a decision. It happens to be that because of when we're delivering it, it's relatively near the end of the year. They have a certain amount of time that could in fact creep into next year. It doesn't necessarily creep into next year. So that's the only component why we introduced that ambiguity in laying out a timeframe. As they could opt-in yesterday if they wanted. So it sort of defines the latest point of when they can opt-in. The second question, right. If they don't opt-in, there's not necessarily anything that we would do immediately, but it could be any of the three things that you might think of. We're very comfortable continuing with this one on our own. We love the program. I think it's a great opportunity. Secondarily, we've already had plenty of inbound interest from others who recognize that there is an opt-in decision. I think most other companies have expressed the thought that they think Gilead would opt-in, but we could consider partnership with another company as well. Bob?

Just on the economics, peter. So it's $150 million opt-in fee should they decide to opt-in. And then we share costs, 50, 50 on the program going forward. And then I don't know if you were getting at this with your question, but obviously if Gilead were to opt-in, then we'd work through the details of any additional studies we might want to add to our clinical development plan together.

Great. Thank you so much.

Thank you. The next question comes from Asthika Goonewardene with Truist. You may proceed.

Hey guys, thanks for taking my question and I'm going to repeat what Jon did and ask a multi part single question here. So on full [Indiscernible], when you think ahead as the right comp for maybe some sort of a pivotal study down the line, what do you think the right comp is? And I asked because Nebo EP [ph] makes is the most logical comp but obviously a very high bar. And related the durable CR rate with Nebo EP is something that is quite attractive about that combination in RCC. But how important is it for you to kind of replicate that or beat that specific endpoint adjacent to the regular primary endpoints that you would consider?

Yes, so this is Dmitri, I can take the question. So the relevant benchmark would be the Checkmate214 study, although of course that is now somewhat outdated. But I think with the mature follow up the data has held up very well. We are building up on the bispecific meaning the data for 42 [ph] has been presented last year at ASMO in kidney cancer. And I think most people objectively would agree it looks at least as good or perhaps a little bit better than IPI-NIVO. Some of the toxicity is a little bit better. So we don't expect, let's say to have to beat IPI-NIVO with cas alone. We know we have a solid CTLA 4 PD1 backbone and then build on top of that the CR rate, indeed the durable, or you say the durable response rate is important. Obviously we don't completely know, but I think it's reasonable to hypothesize that. Let's say one of the things for IPI-NIVO is the primary PD rate. Investigators typically will not use IPI-NIVO in the setting where they really need a fast response for a patient. So that's something we might be able to change, we might be able to get a lower primary PD rate when we, when we build up on it and every other benchmark we expect to be able to deepen or lengthen, meaning longer duration of response because we add a mechanism that really helps out in the long-term, longer progression free survival and hopefully longer overall survival as well.

Yes. And I think just to hit on the primary PD point like that was, I think what got Astra

Yes. And then lastly to add on top of that also the safety profile for HIF-2 targeting specifically Casdatifan would be far more favorable than adding a TKI on top of that regimen. So that's what we refer to the TKI sparing approach. Because first line patients can be on treatment for a very long time, which is cumbersome and let's say a burden on patients if they have to stay on a TKI for a long time.

Great. Thanks so much guys.

Thank you. The next question comes from Daina Graybosch with Leerink Partners. You may proceed.

Hi, I'm going to follow up right along with what Asthika just asked about the trial conduct for both PEAK-1, the combo with cabo and the combo with the CTLA-4 bispecific. And that we've seen in RCC that keeping patients on study seems to be really important that if you have any toxicities and managing those discontinuations can really drive the primary efficacy endpoints. Can you talk through your strategy in both of those trials to manage treatment exposure, particularly as you started with the 60mg dose of Cabo and they haven't always done that in their combination studies. And then also what you're doing with ASTRA to manage TOX with a pretty toxic anti-CTLA-4 as well.

So I'll start with the cabo combination. So two points. I see it as a benefit that we will be starting with 60 the trials where the TKI in this case Cabo wasn't started at full dose, was based on toxicities identified with a combination and therefore you give up on some early higher exposure for an active agent like Cabo. So I think it's important for people to be able to start at full dose. That's the safety data we are generating right now. We already have generated a lot of experience with gas by itself and how investigators manage the toxicity. I think the data that we've shown is very convincing that we have virtually no one discontinuing the drug for toxicity. We have some interruptions and people are able to manage the toxicities and then stay on. So that's the experience we'll also use for the combination. The other thing that makes it a little bit easier in giving guidance is the specific profiles for toxicity for both gas and for Cabo are, let's say Cabo, of course, very well-known and cas relatively straightforward with anemia and hypoxia, no relevant overlapping toxicity. So giving guidance on potential dose reductions will be straightforward. And to make it as clean as possible, that the trial is what we call an active comparator placebo controlled trial. So people on the control arm will be getting Cabo plus a placebo to take out all bias from investigator and patients on the assessment of the AE profile. When it comes to Astra

Thank you.

Thank you. The following comes from Salveen Richter with Goldman Sachs. You may proceed.

Hey, this is Mark [ph] on for Salveen. Thank you guys for taking our questions. We have a question on TIGIT and lung on the ARC-10 day at SITC. It looks clear that TIGIT is adding a survival benefit, but why do you think the benefit on ORR is less clear? And also, how do you expect this data to Translate to the STAR-121 study, where it seems like OS benefit from the dom sim doublet is likely already above KEYTRUDA chemo combo? And when should we expect to see initial data from the Star-121? Is it possible that we could see it in the second half of 2025? Thanks.

So let me start. I think that your first question was about ORR. We think the ORR, there was quite reasonable improvement. Keep in mind this is immunotherapy and it comes up time and time again. The place where you're really getting your benefit is enhancement of OS and it's durability, it's the tail. And that's why it's a profound signal that we're seeing ORR is better. But what you really should be focused on, the world uses ORR as a surrogate for PFS, as a surrogate for OS. And the reason we're out at two plus years and we have that OS data is that that's what you're really looking at. But nonetheless, we don't think there's anything unusual about the advantage on ORR. The second question that you asked was…

How do you expect this data to translate to stock?

So we think the translation. We've already seen an edge gastric in advantage on top of chemo. The thing that. And this is where we think we actually have a huge advantage when we think about the STAR-121 while we stopped ARC-10 for strategic reasons based just on an evolving market that physicians are moving more and more from just using Keytruda to using Keytruda plus chemo even in high PDL-1. What's become very apparent is that the Fc enabled anti-TIGIT have an issue with aes in the context of chemo. So we feel like we're well positioned to even have a stronger advantage relative to any of the competitors at this point in that population. Now the second piece is just from a scientific standpoint, the underlying mechanism is that that anti-TIGIT is enhancing the activity of the anti-PD-1 same phenomena that we demonstrated in the context of GI cancers on top of chemo and we've shown the data from edge gastric and we think that same thing will hold up there. And then the particular advantage is that when you add dom on top of the anti-PD-1 chemo, what we're seeing consistently again is that we're not seeing any enhanced aes. So you really get the full advantage of what the mechanism offers with the FC silent molecule. I think it's important to start to realize there's enough data out there to just bucket into two categories, the FC enabled and the FC silent. So Astra

Sounds good. Thank you.

Thank you.

Thank you. The following comes from Jason Szymanski with Bank of America. You may proceed.

Good evening. Thank you so much for taking our questions and congratulations on both the quarter and the recent presentations. Had a couple of quick follow ups on the PEAK-1 study. In terms of primary endpoint you have PFS. You know, Merck is advancing a number of similar studies with belzutifan with Lenvatinib in a couple of different settings, including second line where the primary endpoint is PFS and OS. Just curious on kind of the decision behind making the primary endpoint PFS and then just kind of fundamentally what do you think you need to do to distinguish yourself from Merck's combinations given their potential to kind of that first mover advantage. Particularly when you know, if you look at say the first line setting, there are a range of different studies, that you might not have the same sort of efficacy but, but kind of that inertia there keeps them well used. Example Keynote 426 looks like 17% still use it even though it's maybe not as good. It's CheckMate 214 or CheckMate 9ER. Thanks.

Yes, so when it comes to treatment preferences, that's the last part of your question. There's a lot of things that go into it. I actually referred to that earlier on. IPI-NIVO for example, is very well recognized for very durable responses and long-term survival benefit. The downside of the regimen is recognized as primary progression. So patients with bulky disease patients who need a response immediately, they're typically not put on IPI-NIVO and based on early readouts, patients with favorable risk were also not given the opportunity. But with longer term follow up it's now very consistent that the IVMC risk categories are no longer considered to be predictive of IPI-NIVO benefit. So that's one of the reasons when it comes to differentiation. It's the question I answered previously. I think in this particular setting Merck is not doing this trial. They don't have a TKI free first line trial which from a physician patient perspective not having the TKI toxicity for the long duration of treatment in the first line by itself is already a very important differentiator when it comes to the second line differentiation PEAK-1 versus LITESPARK 011 having a far more preferred TKI as combination partner. Cabo versus Lenfa the logical choice because Merck owns Lenfar or part of it for us is a major benefit. We consistently hear from physicians that Cabo is much easier to handle than lymphedinib. The dosing complexity of multiple dose levels for lymphedinib, the overall, let's say less well perceived toxicity profile is an important differentiator. The other differentiator we have is even though Merck was earlier with the trial, that comes with the downside that their experience in post adjuvant patients by definition will be very limited to almost non-existing. We will be able to capture those patients so potentially we will get a broader label as well. And then the last part of your question about the dual primary endpoint, I cannot comment on why Merck is doing it. I can only speculate the registrational endpoint is PFS. Whether or not OS is a well powered secondary endpoint or a primary endpoint comes a little bit down to trial size efficiency. However, the only reason to do OS as co primary or better saying dual primary endpoint is if you are not sure if you can hit PFS. So if you hit PFS as primary endpoint obvious to the secondary endpoint and you have an adequately powered overall survival analysis. So in my. Let's say. Let's say from my perspective, doing it as a dual primary endpoint unnecessarily makes the trial larger. But they might have done it because they didn't know what the trial readout would be. Obviously we will have that advantage that the trial that they are doing will have read out before we get to our analysis and in a rare case that we would have to make updates, we can do so.

Got it. So if I'm hearing you correctly, you think between PEAK-1 and LITESPARK 011 you'll have a tolerability edge, do you think you can also have an efficacy edge as well?

Absolutely. If you let's say if I just start with the low bar, if you can stay on a TKI longer because it's better tolerated, you have more benefit. Then of course we are generating the cas data that starts to look differentiated from belzutifan on efficacy, notably the primary PD rate, but also other benchmarks that start or other metrics that start to look better. So we are confident that both the combination partner, but also our HIF-2 alpha inhibitor. Both will be part of the story of a better efficacy and a better safety profile combined.

Perfect. Thanks for the color.

Thank you. The next question comes from Eva Fortea with Wells Fargo Securities. You may proceed.

Hi. Thanks for taking our question and congrats on the progress. A quick one from us. So, for the dom pin combo in the Phase 2 EDGE Gastric, you guided to OS data in 2025. So if I recall correctly, you've only shown data for one arm, but the study included more arms. So I was wondering if you're going to share data from the other arms together in the same update or if this might come at a later time next year. Thanks.

So the guidance indeed is correct. We have committed to the OS data for EDGE Gastric that's maturing right now for 2025. I think we said it before. The enrollment in ARM A1, that's the ARM we presented. And then A2 is the contribution of component ARM for regulatory purposes was not at the same time. They were done sequentially. The data are maturing and I would say it's unlikely we will present it all at the same time because the things don't mature at the same time. But at some point we will present the data if it's mature.

Thank you. Our final question comes from Yigal Nochomovitz with Citi. You may proceed.

Yes, hi. Thanks for the follow up. Just very quickly, I think, Terry, you mentioned in the prepared remarks that you may be in a position to provide updates in the more near term. Does that mean that you might, we might get some of this data that's referenced in the release in this year or just clarify what you meant there. Thank you.

Yes, we didn't want to get too specific, but let's recognize, look at all those studies we have ongoing. So we have cohorts within the study. So we have 150 milligram cohort, we have 100 milligram tablet, we have the 50 and 100 that we've already talked about that are continuing to mature. And what we felt is for sake of transparency and the importance of these data that when we see something meaningful, we're going to look to find a way to get it out there. But right now we don't have any specific plans. But we recognize there's such a large volume of data, we see they're interesting. We want to make sure to take opportunity to update whenever it might be meaningful.

All right, thank you. Got it.

Thank you. There are currently no other questions in queue. This concludes today's conference call. Thank you for your participation. You may now disconnect your line. Thank you.
