Presentation

[Operator]

Good day, everyone, and welcome to today's Q4 twenty twenty four Kura Oncology, Inc. Financial Results Conference Call. At this time, all participants are in a listen only mode. Later, you will have the opportunity to ask questions during the question and answer session.

[Operator]

Please note this call is being recorded. I will be standing by if you should need any assistance. It is now my pleasure to turn the conference over to Patty Bank, Investor Relations. Please go ahead.

[Patti Bank, Managing Director of Investor Relations at Kura Oncology]

Thank you, Angela. Good afternoon, and welcome to Cure Oncology's fourth Quarter and Full Year twenty twenty four Conference Call. Joining me on the call are Doctor. Troy Wilson, President and Chief Executive Officer Doctor. Molly Leone, Chief Medical Officer Brian Powell, Chief Commercial Officer and Tom Doyle, Senior Vice President of Finance and Accounting.

[Patti Bank, Managing Director of Investor Relations at Kura Oncology]

Before I turn the call over to Doctor. Wilson, I'd like to remind you that today's call will include forward looking statements based on current expectations. Such statements represent management's judgment as of today and may involve risks and uncertainties that could cause actual results to differ materially from expected results. Please refer to CURE's filings with the SEC, which are available from the SEC or on the CURE Oncology website for information concerning risk factors that could affect the company. With that, I'll turn the call over to Troy.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Thank you, Patty, and thank you all for joining us. We're continuing the momentum generated in 2024 as we continue to make meaningful advancements across our pipeline. We're poised to submit our first NDA for ziptumenib. We're preparing to commercialize zipto menib as a potentially best in class menin inhibitor for patients with relapsed and or refractory NPM1 mutant AML, which serves as a first step to providing clinical benefit to patients across the treatment continuum. And we've delivered unprecedented development and regulatory pathways for zifedomedib in frontline AML.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Specifically, we've reached alignment with FDA on potential pathways for accelerated approval in The U. S. In both the intensive and non intensive frontline settings by allowing the trials to use MRD negative CR and CR as primary endpoints respectively. We can now report we've also gained alignment with the European Medicines Agency or EMA on the COMADO17 protocol. We believe these advancements could meaningfully accelerate the development and commercialization of ziptometib in frontline AML with top line results from the MRD negative CR accelerated endpoint in the intensive chemotherapy setting anticipated in 2028.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

As we look beyond ziktomedib in AML, we're advancing a strong product candidate pipeline with clinical data updates expected throughout this year. And we're well financed and resourced to create significant value for patients and our stakeholders. So with that, let's turn to specific updates. Starting with our most recent news, earlier this month, we announced positive top line results from COMET-one, the Phase two registration directed trial of ziptomenib in patients with relapsed refractory NPM1 mutant AML. The trial achieved its primary endpoint consistent with a targeted twenty percent to thirty percent CRCRH rate.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

The data have been presented have been submitted for presentation at ASCO. The benefit risk profile for zifdomenib is highly encouraging and the safety profile was consistent with prior As a reminder, zifdomenib is the first and only investigational drug candidate to be granted breakthrough therapy designation or BTD for treatment of relapsedrefractory NPM1 mutant AML. Facilitated by the BTD status of zifdomenib, we completed our pre NDA meeting with FDA and anticipate submitting an NDA next quarter. We believe the combination of safety, tolerability and clinical activity in a once daily oral medication support a competitive profile in the relapsedrefractory market as well as advanced clinical development in those critical frontline indications. And speaking of the frontline AML indications, I'm going to turn it over to Molly to review the unmet need in this patient population as well as feedback we've received from regulatory agencies.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

We're excited to share these updates because we believe the frontline usage of menin inhibitors could be a transformative clinical and commercial opportunity with The U. S. Market for menin inhibitors in frontline AML reaching over $7,000,000,000 annually. Molly, over to you.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

All right. Thank you, Troy. Our intent with zifthamenib has always been to treat AML patients throughout the continuum of care. And despite advances over the last twenty years, there remains a significant unmet need even in the frontline setting. Specifically, even with approved therapies up to seventy percent of patients who achieve a first remission will see their AML return within three years.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

The five year survival rate for AML is only thirty one point nine percent as low as eleven point two percent for patients older than 65. Given the unmet need, we are addressing the frontline AML population through two independent randomized placebo controlled Phase three trials contained within a single trial protocol we call COMET-seventeen. On our investor call a few weeks ago, we announced reaching alignment with the FDA on the COMET-seventeen trial protocol. We were particularly pleased by FDA's willingness to allow the trial to use MRD negative CR and CR respectively as primary endpoints for accelerated approval in the IC and non IC populations. We also stated that we would continue to work with other global health authorities and we're now pleased to report that we have also gained alignment with EMA on key aspects of the COMET-seventeen protocol with both FDA and EMA aligned on the survival based endpoints, including EFS and the intensive chemotherapy combination to support potential full approval.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

By combining two trials under a single protocol, we intend to facilitate study startup and execution. And we believe the protocol is more attractive to clinical sites because it provides treatment options to the broadest patient pool. COMADO17 NIC or non intensive chemotherapy is a trial that will evaluate ziptonimab with venetoclax and azacitidine in newly diagnosed MPM1 mutant patients unfit to receive intensive chemotherapy. The trial will assess complete response and overall survival as dual primary endpoints to support potential U. S.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Accelerated and full approval. COMET-seventeen IC or intensive chemotherapy is a trial that will evaluate ziptumeneb with intensive chemotherapy or seven plus three in newly diagnosed MPM1 mutant and KMT2A rearranged AML patients. The trial will assess MRD negative complete response and event free survival as dual primary endpoints to support potential U. S. Accelerated and full approvals.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

We believe the best opportunity to achieve long lasting remission and extend survival for these patients is to achieve MRD negativity with the first attempt at treatment. And by utilizing this endpoint in COMET-seventeen IC, we are paving the way in the field to establish this new surrogate endpoint. Based upon our current assumptions around the CALMNT-seventeen IC trial, we believe we may have top line MRD negative CR results for the intensive frontline trial in 2028. This is notably faster than we expected and well within the time window funded under our collaboration with Keyoquine for the development commercialization of zetiminib in AML. We look forward to collaborating with our colleagues at Keyoquine to expedite study startup timelines and expect to initiate COMET-seventeen trials in the second half of twenty twenty five.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Not only are we now working to develop ziptumetinib across the continuum of care in AML, but we are also looking ahead to multiple clinical updates later this year across both our menin inhibitor and FTI programs with the goal of developing innovative therapies for patients in areas of unmet medical need. And with that, I'll turn it back over to Troy.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Thanks, Molly. Turning now to other opportunities for ziptamenib, We remain on track to initiate the COMET-fifteen trial in the first half of twenty twenty five, which will evaluate the combination of ziptumenib and imatinib in patients with advanced gastrointestinal stromal tumors or GIST. This will be the first expansion of amatinib inhibitor into solid tumors for us and it's supported by extensive preclinical data. The combination of ziptumetib and imatinib shows robust and durable anti tumor activity in both imatinib sensitive and imatinib resistant GIST preclinical models representing the full GIST treatment continuum. Until now, all therapeutic approaches to treating GIST have been through targeted KIT inhibition via tyrosine kinase inhibitors or TKIs.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Menin inhibitors offer the potential to shift the treatment paradigm and zipto meninib may delay the onset of resistance to the frontline standard of care imatinib or overcome such resistance in patients pretreated with imatinib, a drug to which sixty percent of patients develop resistance within two years. Because of the unique mechanism of action and the demonstrated synergy between ziptomenib and imatinib, this preclinical data has been described by our clinical collaborators as potentially transformative. Given the unmet need and the continued significant interest in novel therapeutic approaches to GIST, we're working hard to initiate the COMADO 15 study, which we believe will begin in the first half of twenty twenty five. And we believe ZYPTO MENID's market potential in GIST may represent an additional $1,000,000,000 peak sales opportunity. Now while much of the focus externally is rightfully on our ZYPTO MEDIB program in AML, our team has also been hard at work on our farnesyltransferase inhibitor programs.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Despite multiple advances, innate and adaptive resistance remains a challenge for many classes of targeted therapies in cancer. We've learned a lot from our growing body of clinical and preclinical data demonstrating the potential of tipifarnib and KO-two thousand eight hundred and six as companion therapeutic agents to augment the antitumor activities of various targeted therapies and to overcome resistance in combination. We're making good progress in our FIT-one trial evaluating our next generation farnesyltransferase inhibitor KO-two thousand eight hundred and six and the dose escalation portion of our current HN trial is now complete. We look forward to presenting the first clinical data for KO-two thousand eight hundred and six as a monotherapy and in combination as well as clinical data from the current HN trial. If successful, we believe KO-two thousand eight hundred and six and other farnesyltransferase inhibitor drug candidates could drive enhanced anti tumor activity and become combination partners to multiple targeted therapies in large solid tumor indications.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

All of this work is made possible through the support of our shareholders as well as the global strategic collaboration we announced in November with our partner Kyokuren to develop and commercialize ZYPTA MENET, funding the expansive AML development program through frontline U. S. Commercialization. Our financial health was strengthened by our team reaching alignment with FDA on potential paths to accelerated approval in the large frontline AML indications. Under our partnership with Kyokuren, we're now well capitalized and resourced to prepare for NDA submission of ziptumetim to continue our preparation for commercialization and to expand and accelerate our ziptumetim development program.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

With that, I'll turn the call over to Tom Doyle for a discussion of our financial results. Tom?

[Tom Doyle, Senior Vice President of Finance and Accounting at Kura Oncology]

Thank you, Troy, and good afternoon, everyone. I'm happy to provide a brief overview of our financial results for the fourth quarter of twenty twenty four. Collaboration revenue from our Keyokaran partnership for the fourth quarter of twenty twenty four was $53,900,000 compared to none for the fourth quarter of twenty twenty three. Research and development expenses for the fourth quarter of twenty twenty four were $52,300,000 compared to $32,500,000 for the fourth quarter of twenty twenty three. General and administrative expenses for the fourth quarter of twenty twenty four were $24,100,000 compared to $14,200,000 for the fourth quarter of twenty twenty three. Net loss for the fourth quarter of twenty twenty four was $19,200,000 compared to a net loss of $42,800,000 for the fourth quarter of twenty twenty three. This includes non cash share based compensation expense of $8,600,000 compared to $7,200,000 for the same period in 2023. As of 12/31/2024, Cura had cash, cash equivalents and short term investments of $727,400,000 including the upfront payment of $330,000,000 from Keyo Occurant compared to $424,000,000 as of 12/31/2023.

[Tom Doyle, Senior Vice President of Finance and Accounting at Kura Oncology]

We believe that our cash, cash equivalents and short term investments as of 12/31/2024 will be sufficient to fund our current operating plan into 2027 and combined with payments anticipated to be received under our collaboration agreement with KeyoKaren should support our ziptominid AML program through commercialization in the frontline combination setting. With that, I now turn the call back over to Troy.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Thank you, Tom. Before we jump into the question and answer session, let me just quickly lay out our anticipated upcoming milestones. We expect 2025 to be a robust year of research, development and pre commercial activity for the company with several expected data readouts across multiple programs. Notably, we look forward to potentially providing updates across our pipeline at every major medical meeting this year. For ziptumenev, we expect to submit an NDA in relapsedrefractory NPM1 mutant AML in Q2, present top line data for COMET-one for presentation in Q2, present preliminary clinical data from the COMET-seven Phase 1b expansion cohort evaluating ziptomenib with intensive chemotherapy at a medical meeting in Q2, initiate the COMET-fifteen trial evaluating ziptomenabenematinib in patients with advanced GIST in the first half initiate two independent Phase III registration enabling trials in frontline intensive and non intensive AML in the second half present preliminary clinical data from the COMET-seven Phase 1b expansion cohort evaluating zifdomenib with venetoclax and azacitidine at a medical meeting in the second half and nominate a next generation menin inhibitor development candidate for use in diabetes in mid-twenty twenty five.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

For our farnesyltransferase inhibitor programs, we expect the following milestones initiate one or more expansion cohorts of KO-two thousand eight hundred and six and cabozantinib in patients with advanced renal cell carcinoma in the first half present data from the Phase one monotherapy dose escalation of KO-two thousand eight hundred and six in patients with RAS mutations in the second half present data from the Phase one trial evaluating KO-two thousand eight hundred and six and cabozantinib in patients with renal cell carcinoma in the second half and finally present data from the dose escalation portion of the current HN trial evaluating tipifarnib and delpelasib in PIK3CA dependent head and neck squamous cell carcinoma in the second half. And with that, Angela, we're now ready for questions.

[Operator]

We'll go first to Lee Watson with Cantor Fitzgerald. Please go ahead.

[Li Watsek, Director at Cantor Fitzgerald]

Hi, everyone. Thank you very much for taking my questions. Troy, you guided to the Phase III top line in frontline intensive AML setting in 2028. Just curious what assumptions went into that guidance and anything you can share on the trial size that plan or enrollment timeline?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes, Lee, thanks for the question. We thought it was important because we've been getting questions from both analysts and investors to give people some idea of the timeline, particularly now that we've gained alignment with both FDA and EMA, but specifically with FDA on pathways to accelerated approval in The U. S. And we feel comfortable, we think we're being conservative, but we feel comfortable saying that we think we can have top line results for that accelerated approval endpoint in 2028. We'll give you more detail on the trial size, the powering, etcetera, as we get a little bit closer to the trials actually going live and being posted on clintrial.gov.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

That's being driven both by we're just doing some further refinement and we're in the process of study startup. But that is meaningfully faster than what we were projecting for prior to our engagement with the health authorities. And obviously, it positions us well in the context of the funding received under the Killer Kirin collaboration. I would say look forward a little later this year for more updates Lee not only on the intensive trial that you're asking about, but the non intensive trial as well. The sizes, the powering and then how do we get to both the potential for accelerated and then the survival based endpoints. I hope that's helpful.

[Li Watsek, Director at Cantor Fitzgerald]

Yes, understood. And then just wondering what the remaining items meeting?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

No. I mean, that's thank you for the question. I don't know if at the time we made that announcement a few weeks ago, if people sort of read over that. We were deliberate actually in not saying anything until after we had the pre NDA meeting. And the team Molly and the team did a phenomenal job of again gaining alignment with the agency on all the aspects of the submission.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Clearly, the clinical data is always the long pole in the tent and that's what is driving the timing of the submission at this point. But given that we have BTD and given that we've had pretty constructive engagements not only on the monotherapy, but now in the combination setting with FDA, we feel like we're in good shape. And again, we're guiding to a second quarter submission. The team is doing everything in its power to accelerate those timelines. But so far, I think we have everything we need and we've gotten very it's been a very constructive series of interactions with the agency. Angela, should we go on to the next question?

[Operator]

We'll go next to Jonathan Chang with Leerink Partners. Please go ahead.

[Yen-Der Li, Biotech Equity Research Analyst at Leerink Partners]

Hi, this is Yander Li on for Jonathan Chang. Thanks for taking my question. So the first question I have is that when we look at the commercial opportunities for ziptonumab, I guess the most important variable is the treatment duration. Could you share the reason behind your confidence that first line AML patient will be able to stay on the treatment for more than a year? Thank you.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes. Let me actually, Jensur, thank you for the question. I'm actually going to do this in two parts. Maybe Molly can speak to how we've informed the duration of treatment from our experience with COM701 seven and then I'll ask after she answers, I'll ask Brian to comment on how does that translate into our assumptions around the commercial potential in the front line. Molly, if you would?

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Sure. As Troy alluded to the seven trial has been highly informative to how we handle designing and our expectations for the seventeen trial and for use in the frontline in general. I think initially we thought that especially with the intensive chemo setting, the use would be some induction, some consolidation, then the patient will go off to transplant and potentially some proportion would come back after transplant for post consolidation maintenance. What we're seeing is incredibly different, especially for the NPM1 patients that make up such a large majority of the patient population. These patients are coming on doing induction, consolidation and post continuation consolidation immediately with few trips to transplant, except for the KMT2As who get to transplant whenever possible and then almost universally either have returned or intend to return to post consolidation, post transplant maintenance.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Similarly with the VENAZA, we have patients that are staying on for very prolonged periods of time on treatment in the front line, even when or if the backbone drops away or is decreased in intensity or used a little bit differently from when it's used prior to gaining control of disease. So we're seeing good prolonged use in each of these that was probably more significant than what we initially thought. But with that, Brian, I'll turn it over to you to how you see that translating.

[Brian Powl, Chief Commercial Officer at Kura Oncology]

Sure. Thank you, Molly. And based on the assumptions that we are observing or what we've observed in the trial, like Molly said, we do think there's a tremendous potential that menin inhibitors could transform the treatment of AML with patients being able to get on therapy, stay on therapy for a long period of time. When you think about our opportunities with in as we've stated that we think this could be a choice that it could be a $7,000,000,000 potential market. If you're able to get patients to receive a MET inhibitor for eighteen to twenty four months and there could be potential for longer than that, but if you think between that eighteen to twenty four months in the FIT intensive chemo population and then eighteen months plus within the non intensive that gives you a significant duration that we think really could reflect that transformative potential and really kind of align with what we've seen in some other markets like multiple myeloma where long duration of treatments with IMIS have really transformed the market and also the outcomes for patients.

[Yen-Der Li, Biotech Equity Research Analyst at Leerink Partners]

Got it. Thanks for the comprehensive answer. And I have also a follow-up question related to that. So for the COMET seventeen intensive combination study, if I recall correctly, the patient will include both on transplant and non transplant chemo as consolidation options? And is there a concern about the imbalance of consolidation treatment receiving each arm?

[Yen-Der Li, Biotech Equity Research Analyst at Leerink Partners]

And do you have any like protocol to mitigate such concern? Thank you.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes. Yander, let me let Mollie speak to that. Molly, do you want to take a shot at Yander's question?

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Sure. Well, starting with the KMT2A patients, we really don't think there'll be an imbalance. The intent is always to get them to transplant. So it's likely that all that can will get to transplant. With regards to the NPM1 mutants, it may be that some of the patients do better, hopefully they do better in the active arm and so are less requiring of transplant.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

So we've built in multitudes of sensitivity analyses to be able to account for that. But ultimately, we built the trial size, the trial powered the trial, taking that into account and weighing in the effects that the KMT2A patient population would have on the overall population and being able to assess the effects of transplant or no transplant in the active versus placebo arms, if that's helpful.

[Yen-Der Li, Biotech Equity Research Analyst at Leerink Partners]

Yes, that's helpful. Thank you so much.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Thank you, Yander.

[Operator]

We'll go next to Jason Zemansky with Bank of America. Please go ahead.

[Jason Zemansky, Vice President, Equity Research, Biotechnology and Pharmaceuticals at Bank of America Merrill Lynch]

Good afternoon. Thank you so much for taking our question and congrats on the progress. I was curious as you look to the additional dose expansion data from the seven study, what in your view would be encouraging from the seven plus three combo as you start to expand into the non adverse risk group. Specifically in terms of MRD negativity, what gives you what would give you confident that addition of Zifto would ultimately give you a survival benefit?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes. Jason, thanks for the question. I'm going to ask Molly to speak to it. But Molly, maybe you can take a minute and help folks understand how we think about the MRD negativity and sort of what the standard is as you answer Jason's question?

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Absolutely. So what we understand, obviously we're part of a consortium of a large amount of pharmaceutical companies that are really looking into this MRD negativity for this patient population. And we have access therefore to both published and unpublished data from those other pharmaceutical companies as well as from some of the key opinion leaders that are really advancing MRD as an endpoint in AML. So we understand that a good outcome for these patients with the current treatments available would be to see about a forty percent to forty five percent MRD negativity in the bone marrow. And that's for the better performing patients.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

So your MPM1 for instance. So we would expect that any incremental increase in that would be due to the influence of having a targeted agent in the mix as well and maybe getting into the fifty percent and sixty percent MRD negativity rate would be encouraging for translation into the overall survival as well. So that's the way we're thinking about our data as we continue to look at these patients enrolling. Obviously, you've seen the patients do very well from a response perspective. So I wouldn't expect to see much difference in that.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

They're going to continue to do well. But it's as you're pointing to the MRD that is what we're looking at to make sure we're headed in the right direction.

[Jason Zemansky, Vice President, Equity Research, Biotechnology and Pharmaceuticals at Bank of America Merrill Lynch]

Got it. Makes sense. Thanks for the color, Molly. And maybe just a quick follow-up here. Noticed the other mutations bucket about ten percent to fifteen percent of the population.

[Jason Zemansky, Vice President, Equity Research, Biotechnology and Pharmaceuticals at Bank of America Merrill Lynch]

Curious, what does it take to get there to that group of individuals? And what gives you confidence, I guess, that Amenet will be active in these subtypes?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes. I'll take that, Jason, and then Molly can add her comments. We have seen what we call off target activity, not only with the SETT2 RUNX1 patient, but we've seen other patients as well who appear to be receiving clinical benefit from zipta menet in the monotherapy studies. One of the obvious areas there of course is split three. And of course there's an approved standard of care in the intensive setting.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

There's actually a couple of them, less so in the non intensive setting. But if one were to look at KMT2A, NPM1 and then FLT3 that gives you approximately half of the eligible AML patients. We have a study ongoing with giltaritinib in the relapsedrefractory setting that is supporting the notion that one can combine a menin inhibitor and a FLT3 three inhibitor with appropriate safety and tolerability. Clearly, if you want to go into the front line, you need to go with an approved agent. There are a couple Midastorin and Quasartinib.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

We've guided that we anticipate starting a front hopefully, I should say potentially a frontline combination study of zifdomenib plus Quisartinib in the and again, we're optimistic that we can go straight into the front line because now we have adequate safety of ziptomenib both as a monotherapy and in combination. So that would likely then give it would require us to go beyond what we're doing with the KAMADO17 trials. But as I think we mentioned when we talked more about the deal with KILICURIN, the collaboration is structured and we are actually funded to run multiple global Phase III trials and one could potentially be an upcoming FLT3 trial. So there are a lot of priorities at Coron at the moment. Clearly the NDA submission, the pre commercial activities, COMADO seventeen, but FLIP three is very much on the team's mind and something that I think you'll see us move toward here in the second half.

[Jason Zemansky, Vice President, Equity Research, Biotechnology and Pharmaceuticals at Bank of America Merrill Lynch]

Got it. Appreciate the feedback. Thanks.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Sure.

[Operator]

We'll go next to Peter Lawson with Barclays. Please go ahead.

[Peter Lawson, Analyst at Barclays Capital]

Hey, thanks, Troy.

[Peter Lawson, Analyst at Barclays Capital]

Wonder if you could just kind of took a few minutes just around where you stand for diabetes and the nomination of the candidate and kind of where that fits in into your priorities and how you're thinking whether it's type one, type two or particular stage of the disease? Thank you so much.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes, Peter. That's appreciate the question. That was not wasn't expected, but is welcome. So a couple of comments.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Going for everybody's benefit, we put out data at the American Diabetes Association meeting last summer. That data shows four things, four hallmarks, glucose lowering, stimulation of insulin production, insulin sensitization and selective expansion of pancreatic beta islet cells. To our knowledge, all of the existing anti diabetics do various of three of those four. We haven't yet had an agent that selectively expands pancreatic beta islet cells. And that's really kind of the holy grail.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

The work that we did pre clinically is with ZYPTO MENAV. We wouldn't take ZYPTO MENAV forward into diabetes for safety reasons, pricing reasons, IRA reasons. That's why we've been very clear from the get go, if you're going to go into diabetes, you go with a different molecule. And Peter, we have been carpet bombing the chemical space in menin for now going on three years. So we have molecules that have different PK profiles, different tissue distributions.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

We really feel like one can actually ask that question in the right way with chemical with drug candidates. To your specific question, in our internal work, our work with investigators in KOLs and our work with certain, shall we say strategic partners that know diabetes well, there really is an interest in exploring both type one and type two. We wouldn't put restrictions on those populations today based on what we know. It appears that if one has some reservoir pancreatic beta islet cells, there's probably good applicability. What we want to be clear about is, there is potentially a lot of value here to be created for patients first and foremost, but also for current shareholders, but we have to do that in the right way.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

We are a specialty oncology company. We know what we know. If you see us work in diabetes, we could do some initial we can do the preclinical work, maybe some initial clinical work, but we recognize you pretty quickly need to get that into the hands of a company that is going to be invested from the get go at running the large global Phase III that would be required to test those hypotheses. So there are a lot of creative ways one can do that. The good news is we have the chemical matter.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

I think we have as good due to Francis Burrows, who's not on the call with us today, our CSO. We have as good an understanding as anyone about menin inhibitors and diabetes. At the moment, the nearest term milestone is nomination of a development candidate. We're going to take our time because the demands on the therapeutic index are quite different than oncology. And you want to have the right molecule, the right drug like properties and the right therapeutic window.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

And we want to have a molecule, Peter, that has the potential to go the distance. Does that answer your question?

[Peter Lawson, Analyst at Barclays Capital]

Yes, that's great. Thank you. I guess there was a bread crumb in there for me just kind of what's the right route forward so you kind of capture the potential upside of something like diabetes yet not dilute yourself?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

What's the right say that again, Peter, what's the right what?

[Peter Lawson, Analyst at Barclays Capital]

What's the right strategy there? Is it like a JV partnership? How should we think that actually you kind of capture upside yet you don't lose your focus around oncology?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes. So, yes, understood. I mean a few things there. I think you want to make it you want a flexible structure that allows you to cleanly separate the biology and importantly the IP, the oncology from the non oncology. Ideally, you want to make certain that the value is captured for current shareholders.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

This could be the first novel mechanism of action in diabetes since GLP-one, but I don't think we're under illusions that Churro shareholders are looking for royalties a decade out from now. So we want to be thoughtful about how we do it. You would ideally, Peter, look for look to a structure that really allows you to go very fast, may allow you to take more than one molecule forward and ideally allows you to monetize that IP in a way that you could again either extend runway or do other creative things, stock buybacks, etcetera. So fortunately, this we're not inventing the wheel here. There's lots of wheels that have been demonstrated to work, but you'll see those are sort of the themes that we're looking at.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

And the good news is this is essentially a call option on the story. I think it's scientifically and clinically really interesting. It is not as high a priority as what we need to do in AML in this year and everyone at Cura knows that. But we would be we wouldn't be doing our best for patients if we didn't find a way to get this into the hands of the clinicians and let them really test the hypothesis.

[Peter Lawson, Analyst at Barclays Capital]

Great. Thank you so much. Thanks for letting me deviate the conversation away from AML. Thanks, Troy.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Sure.

We'll go next to Phil Naidoo with TD Cowen. Please go ahead.

[Ernie Rodriguez Dumont, Vice President - Biotechnology Equity Research at Cowen and Company]

Hi. This is Diego Rodriguez for Phil. Thanks for taking our questions. I will start with I have two questions. First one is on the competitive landscape.

[Ernie Rodriguez Dumont, Vice President - Biotechnology Equity Research at Cowen and Company]

Now that we have that you have at hand the results from COMINT one and we had updated data from several other many inhibitors that were presented at ASH. How do you think or expect SIFTA to be differentiated from the others? Or how do you see the competitive landscape ultimately playing out?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes. Thanks for the question. I mean, that's a big question, but we'll try to be maybe brief and hit the high points. If we go back to so there's an opportunity to do the very best you can for relapsed and refractory patients with NPM1 mutant leukemia. That's what we're targeting with ZYPTO.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

And we think we're going to be very competitive in that space. As you heard Molly say, and I think Brian echoed, when you talk to the physicians who treat these patients day in and day out, they will say to you, you need to treat early and you need to treat in combination. And ideally, you keep these patients in remission for as long as you can. What ZYPTO is allowing the physicians to do is to keep these patients on therapy. Regardless of whether the backbone is intact or the backbone has fallen away, these patients are staying on zipto menop for prolonged periods of time in our seven study.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

As Molly said in both the intensive with seven plus three and the non intensive with VENAZA. The VENAZA may fall away, but they're remaining on ziptummenib. And in the case of NPM1, many of them are not going to transplant. Why is that? It's because of course, the compound has meaningful clinical activity, but it also has a safety, tolerability and convenience factor that allows for once a day daily dosing with very good tolerability.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

We've been touting this from the get go and continue to believe that as you look toward those large frontline indications, combinability is going to be key. That is what is going to give patients the best chance to stay on therapy for prolonged periods of time. We have no QT prolongation, no myelosuppression, once daily dosing, no clinically meaningful drug drug interactions. It's a very easy drug to use. For folks who may be listening, I would refer you to when we did our investor event after the ASH presentations, the commentary that Doctor.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Zaidan gave around his experience with intensive chemotherapy patients. That's really how we see ziptumenev being differentiated from the competition.

[Ernie Rodriguez Dumont, Vice President - Biotechnology Equity Research at Cowen and Company]

Got it. Thank you. That's very helpful. And on the earlier type pipeline, the 15 on GIST, you have mentioned the potential to delay the onset of resister in that population. So as we look forward to the clinical data in the future, do we is it more relevant for us to be looking at the duration of the response aside from ORR?

[Ernie Rodriguez Dumont, Vice President - Biotechnology Equity Research at Cowen and Company]

Or how should we be looking at the data once it's ready to come out?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes, that's a good question. And Molly, let me ask you if you can speak to that and I'll just summarize the question. What are we looking for in terms of clinical evidence of activity in the 15 study combining zifediminib with imatinib? What are we looking to do clinically?

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Yes. So I think there's several different things we could see and each would be very positive and very confirming of what we think the combination could do. For those patients that are on imatinib and starting to fail, hopefully we're able to save that response and get that patient back into a response. Patients that are on imatinib and this is something we will be exploring at certain points, but after we finish most of the dose escalation, seeing if you can deepen the response to imatinib. Most of the patients that respond to imatinib do so only partially.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

You rarely see a complete response. So getting patients into a complete response would also be obviously of great importance. And then finally, as you referred to the durability. So having a good duration of that response, a good progression free survival, prolonging the usual two years till resistance that these patients are able to stay on drug with their imatinib backbone. So those are the three areas that I'm looking to deepening of the responses, saving responses once they've been lost with imatinib and then maintaining the responses to imatinib for prolonged periods of time.

[Ernie Rodriguez Dumont, Vice President - Biotechnology Equity Research at Cowen and Company]

Thank you. And thanks for taking our questions.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

My pleasure.

We'll go next to Brad Canino with Stifel. Please go ahead.

[Dara Azar, Associate Vice President , Biotech Equity Research at Stifel Financial Corp]

Hi. This is Dara Azar on for Brad. Thanks for taking our questions. First on the frontline development, do you expect EMA to have an entirely different opinion than the FDA on MRD negativity as a regulatory endpoint? And maybe tell us more on how you expect to conduct a 17 trial to support a global approval? I do have a different question after this.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Okay. Yes, those are two good questions. Molly, would you like to take those?

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Sure. So I do think that there's the potential for EMA and FDA to be at slightly different points and where they would be accepting of MRD negativity, although both regions recognize the MRD negativity is clearly a very significant piece of getting these patients into a successful remission. I think what you're kind of drawing attention to is are we going to do things differently between The accelerated approval endpoints were always intended to be for The United States, whereas we intended the survival based endpoints to support the approvals in the EU. Does that help?

[Dara Azar, Associate Vice President , Biotech Equity Research at Stifel Financial Corp]

Yes. Helpful commentary. Now, switching over to relapsed and refractory, will the data cut and patient denominators match between your upcoming medical meeting presentation? I suppose first would be ASCO abstract and the NDA submission. Thank you.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes, Molly. Sure. Molly, can you take that?

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Yep. So we will not be adding patients to the denominator. We submitted to the FDA the full patient pool. We submitted to ASCO the full patient pool. So you would see the same group of patients, same patient population in both.

[Dara Azar, Associate Vice President , Biotech Equity Research at Stifel Financial Corp]

Thanks for the questions.

[Operator]

We'll go next to Charles Hsu with LifeSci Capital. Please go ahead.

[Charles Zhu, Managing Director, Senior Biotechnology Research Analyst at LifeSci Capital, LLC]

Hey guys. Good evening and thank you for taking the questions. Maybe one outside of AML. So maybe one program where frankly lots of folks have very little attention to. The Farnousle trans races KO-two thousand eight hundred and six, I mean like, I don't know, what would you say you need to deliver here in the second half of twenty twenty five in order to gain more conviction on this asset, also to gain more conviction from the investment committee on these, especially not only in context with the assets themselves, but also in context of some of the emerging competitive landscapes in areas like RAS or renal cell carcinoma? Thank you.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes, Charles. Thanks for the question. I mean, very simply, you're looking to do something that people have been trying to do for a long time, I think largely without success. And that is, how do you develop a companion target to some of these big oncogenes? People have looked at SHIP2, they've looked at SARS1, in the case of KRAS.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

People have tried to combine inhibitors of the MAP kinase pathway and the PI3 kinase pathway largely without success. But we know and you see it in every single study, you get responses in if you're lucky half the patients, the other half don't respond and many of the responders actually eventually relapse due in many cases to mechanism based resistance. So to your question, what are we looking to do? You're looking to show that you can combine a farnesyltransferase inhibitor with these other targeted therapies with acceptable safety and tolerability. You can't skip over that because that's what kills most combinations.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

You can have the best preclinical data in mice and if the patients can't tolerate it, you're not going anywhere. So that's first and foremost. The second is you're looking for evidence of activity initially and these are Phase one studies, right, dose escalation studies. You're looking for evidence of clinical activity that is unanticipated, unexpected. So I mentioned to you in the case of both tipifarnib and alpelastib, in PI3 kinase mutant head and neck, alpelastib delivers at best stable disease, tipifarnib is inactive.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

So what are you seeing when you combine those two in that population? In the case of RCC, the one that you mentioned, are you seeing activity either after the appropriate standards of care and in particular in combination with gabozantinib. What are you looking for? If you see clinical activity in patients who have failed the existing therapy and then you and this is what Molly was alluding to with GIST. Patients who you give them the drug, they begin to progress, then you give them your novel agent and the drug again and you restore the response that's and you have good tolerability that's telling you keep going, right?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

You've got an encouraging signal. I think the thing that has us encouraged continuing to move forward is we're evaluating two thousand eight hundred and six and tipifarnib really as a sort of a test case in TKIs, in PI3 kinase alpha and in KRAS driven tumors. Each of those are big potential blockbuster opportunities. If we're able to deliver this, that's I think that could really be a significant contribution to patients. We have the ability to take our time.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Two thousand eight hundred and six, we're confident is a very good drug and we look forward to sharing data with you and the community in the second half of the year, hopefully at a major medical meeting.

[Charles Zhu, Managing Director, Senior Biotechnology Research Analyst at LifeSci Capital, LLC]

Great. Thank you.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Sure.

[Operator]

We'll go next to David Dye with UBS. Please go ahead.

[David Dai, Director at UBS Group]

Great. Thanks for taking my questions. Two from me. Actually one is just on the, react to refractory people data, Rita at ASCO. You mentioned that it will be a later data cut.

[David Dai, Director at UBS Group]

So could you maybe just help us understand how the later data cut could change the CRCRH rate? And then on that, do you can you just tell them more about the baseline characteristics of the patients that we'll potentially see? Would you expect the patients to have similar prior venezoclax treatment?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes. David, let me just correct you on something you said, because we may have miss stated it or you may have misheard it. It's not a later data cut. What we said was, it's the same it's effectively the same data cut the agency is seeing. We're not trying to slice and dice it.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

And as Molly said, we're not going to be looking to add patients to the denominator or the numerator. So it'll be the same data cut that is going in as part of the NDA submission. On the baseline characteristics, Molly, could you answer David's question to the extent that we can?

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Yes, sure. Expect to see similar patient characteristics to what we saw in the Phase one. Again, patients are heavily pretreated, most have seen venetoclax, many have had prior transplants. It's really largely a very similar patient population to the one for whose data we've already presented.

[David Dai, Director at UBS Group]

Got it. That's really helpful. And then just on the frontline COMINT 17 trial, how should we think about the contribution of Curekuren on the clinical trial? And do you think they could potentially have them help out with some of the clinical trial developments that can expedite the clinical trial development?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Molly, do you want to speak to that?

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Yes. I mean, that's absolutely the hope. They're very good partners to have. They have a good presence in areas we don't like the EU, like Japan. So they would be very good partners on the ground helping to get sites up and running.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Of course, they are also good standing boards for our particular strategies, especially in some of the regions they're most familiar with. So we expect them to be well to continue to be very big help on both design and study startup.

[David Dai, Director at UBS Group]

All right. Thank you so much.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Thanks, David.

We'll go next to Justin Zelman with BTIG. Please go ahead.

[Justin Zelin, Analyst at BTIG]

Thanks for taking our question. Maybe just a follow-up on Charles' earlier question. I also find the FDIs quite interesting and also important given that you have wholly owned economics on the programs and are the only companies developing the programs. Troy, you mentioned the combination approach with KRAS, which I find quite compelling. Can you talk to whether you have preclinical data with the pan KRAS inhibitor? And just how you kind of view that landscape on the combination potential with the pan KRAS inhibitors or the KRAS variants?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes. Justin, thanks for the question. We do have non clinical data with both mutant selective and PANCRAS inhibitors. You do see potentially synergistic activity with both. It depends interestingly on the cellular and the organ context.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

So for example, you see better synergy in colorectal than you do in pancreatic. That's not terribly surprising. Even though we think of both of them as being RAS driven, it does appear that colorectal is probably more multigenic. And one of the things we're looking to do, Justin, I mean, when we started this combination, we went with adagracin because frankly it was one of only two commercially available KRAS inhibitors with a well understood safety and tolerability profile. We are eager for the KRAS field to catch up to us.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

There are opportunities to combine with G12D, G12V, PAN RAS and we are that's an opportunity. It's also a challenge of how do you think about doing what's best for patients while at the same time threading the needle to get to the market and ideally take the largest segment of the market. So, we are in discussions with a number of different folks. I would say we've been encouraged thus far by the combinability of farnesotranspirase inhibitors with these other agents. That and when back in the day before we started dosing with tipifarnib and alpelastib, people had said, what are you most worried about?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

And I would say to them, it's the tolerability. You don't that is what most of the time does these combinations in. Two thousand eight hundred and six has shown itself to be very well tolerated in combination. Now it really comes down to to what kind of clinical activity are we seeing and how do we think about that forward development strategy. And what you're seeing what you will see us do Justin is likely move multiple FTIs forward to give ourselves optionality in light of competitive dynamics, pricing, IRA, etcetera.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Because as I said, each of those tumor types could be an entire program unto itself. And we want to think carefully about how we do that. We've made a very sustained investment in farnesyltransferase. I think we're ahead of everyone else. It starts to get interesting here in the second half as we start to show clinical data.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

I would encourage anybody who's interested. We've got a ton of preclinical data available on our website. As I said, we will look to do some sort of events probably ahead of the clinical data with the analyst and the investor community to help educate folks on how do you think about FTIs, what's the scientific rationale, what's the current landscape, how should you think about the clinical data, look for us to do that in the second half. We want to get on the other side of the COMET-one data, on the other side of the seven data, but that's it's something to look forward to in the second half.

[Justin Zelin, Analyst at BTIG]

Thanks, Trey. And maybe just quickly, how can we think about business development activities from Chira either in licensing or out licensing throughout the rest of the remainder of this year and into next?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

In licensing, I mean, we get pings probably several times a week. We have yet to pull the trigger on anything. We have a very high bar to bringing anything in given everything we have going on. Our goal would be to deliver a blockbuster in AML, a blockbuster in GIST and a blockbuster in one of those FTI indications. I think if we could do that, we don't need to add anything else to be quite frank and we're funded to do that.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

But there are a couple of interesting opportunities. In terms of out licensing, at the moment, our focus is really clinical collaborations. How can we generate clinical data that will help inform the development path? You'll see that we've prioritized drugs that are either that are ideally standard of care and generic or generic in the foreseeable future because it gives you and anyone in the future maximum optionality. But when we start to think about KRAS, PI3 kinase, those are going to be novel agents and you need to find people that have a shared vision of what you might do together.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

So I don't know I don't know about BD as much as clinical collaborations. Justin with one footnote and that would be back to Peter's question around diabetes. I think we have to think carefully about what we do there. And I would say stay tuned.

[Justin Zelin, Analyst at BTIG]

Got it. Some more partnerships rather than DTE. Okay, got it. Thanks so much, Troy. Thanks for taking our questions.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Our pleasure. Thank you.

We'll go next to George Farmer with Scotiabank. Please go ahead.

[George Farmer, Managing Director at Scotiabank]

Hi, good afternoon. Thanks for taking my questions. A couple from me. Troy, you and Molly indicated on your last call that we would be seeing a slightly later data cut at the medical meeting versus what you would be submitting to the agency. And now you're saying it's going to be the same cut.

[George Farmer, Managing Director at Scotiabank]

I was perhaps you could elaborate on why that shift. And then also in your conversations with the agency agreeing to this MRD endpoint, That seems to be very different than how the agency has approached their hematologic indications like multiple myeloma, where they call the committee to talk about this. Can you talk about your interactions with the agency? And do you think this is something that we could see with other programs beyond Cures? Thanks.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Yes. Maybe on the first question, I mean, there's a we're talking about a ton of data here, right? So there's what's in the abstract, there's what's at hopefully at ASCO, potentially at ASCO, and then there's what's going to the FDA. Those are slightly different, but they're all contemporaneous. And to Molly's point, I don't think they're going to move the numbers around significantly, which is what people are really getting to.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

To. The numbers that you see in the abstract and at the ultimately the poster or the oral presentation should be consistent with what we see with what we will be submitting to FDA for review. So to the extent that we no intention to create any confusion there, it's just you're talking about ever larger sort of data packages, if you will. On the engagement with the agency around MRD negativity and how that might differ from myeloma, I think again, our work with the IMPACT consortium is instructive. But I'll let Molly speak to that because she's really been spearheading that George. Molly, do you want to take George's question?

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

Sure. No, as we've said, we are working with a consortium of other pharmaceutical companies that are really working to gather the data that's on FDA's checklist for establishing the relationship between MRD negative CR and overall survival. Ultimately, as we've said before, we don't need any more data right now to get our trial started. But obviously to confirm the endpoint and to analyze the data, we'll have to be submitting a larger data package. It's hard to know in three years or less more than likely, if when we start submitting these data packages that the FDA will be looking at in advance of our data to start to establish MRD negative CR as a surrogate endpoint, if they'll be calling a committee or not.

[Mollie Leoni, Chief Medical Officer at Kura Oncology]

They seem to be very accepting of the fact that their own internal expertise suggests that it is in fact a good surrogate endpoint once we get their data packages together. And so we will see how that plays out over the coming years. But we expect them to do a lot more work in the area. We're going to help support them doing the work and all of this work is just expected to be submitted at the time we submit our own data supporting the accelerated endpoint.

[George Farmer, Managing Director at Scotiabank]

Okay, great. And then when you Sorry.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

I was going to just add to that. This is not unprecedented. Cronos, a couple of years ago reported that it had alignment with the FDA developing its sick inhibitor in NPM1 mutant frontline AML as well. So as Molly indicated, our interactions have been there's a willingness to create a pathway for accelerated approval. Obviously, we have to run the trial and show up with the data, but there's a willingness to consider that and that builds on, as you indicated, myeloma and some of the other areas where we've seen that endpoint become widely accepted. Just wanted to add that point.

[George Farmer, Managing Director at Scotiabank]

Yes, because that's very helpful. And when do you think you would capture the EFS endpoint from the study?

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

We haven't. Yes, we haven't guided. So we've been careful. We're still working through putting those dates down. We want to make certain that when we put dates out, we can stand behind them.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

All of these endpoints are driven by number one, enrollment assumptions and then other assumptions around time on therapy and survival and whatnot. Give us a bit more time. We'll come back again with more details on the trial design, more details on the timing of the endpoints later this year as we get closer to study startup.

[George Farmer, Managing Director at Scotiabank]

Okay, great. Thanks very much Troy.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Our pleasure. Thanks George.

Our last question comes from Salim Syed with Mizuho. Please go ahead.

[Analyst]

Hi, this is Eric on for Salim. Thanks for taking our question. Just another divergence from AML real quick, if you don't mind. What with the whirlwind of changes at FDA, staffing cuts, just wondering if you come across anything in your engagement with FDA recently that has given you any cause to update your expectations on how quickly they're able to come back to you, their share of timelines, whether things might be picking up or slowing down due to anything that's going on from the FDA side at this point? Thanks.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

Sure. In our immediate interactions with the agency, they have been just incredibly professional, timely, cooperative. We're not getting any indication. They are such good partners. We're lucky as an industry to have such a good regulator.

[Troy Wilson, President and Chief Executive Officer at Kura Oncology]

We are you are going to see us be conservative on our timing and our guidance. I don't think we'll be guiding to things coming in ahead of schedule because you just never know in this environment, right? And we have no idea what's going on internally at the agency. So we're just going to do everything we can to give them the data that they need to be able to evaluate not only ZYPTO MEDNAV in the monotherapy, but as we have the frontline studies, the GIST studies, the FTI studies and then hope for the best. I don't think people should necessarily be guiding to more aggressive timelines, but we're not getting into any indication yet that there have been major disruptions at the FDA. And I think that's let's hope that that continues.

[Analyst]

All right. Very helpful. Thank you.
