Good day, everyone, and welcome to the Syndax first quarter 2021 earnings conference call. Today's call is being recorded. At this time, I would like to turn the call over to Maghan Meyers of Argot Partners. Please begin. Thank you, operator. Welcome, and thank you to those of you joining us on the line and the webcast this afternoon for a review of Syndax's fourth quarter 2021 financial and operating results. I'm Maghan Meyers with Argot Partners, and with me this afternoon to discuss the results and provide an update on the company's progress are Michael Metzger, Chief Executive Officer, Dr. Briggs Morrison, President and Head of R&D, and Alex Nolte, Chief Accounting Officer. Also joining us on the call today for the question and answer session is Dr. Peter Ordentlich, Chief Scientific Officer, and Dr. Anjali Ganguli, Chief Business Officer. This call is being accompanied by a slide deck that has been posted on the company's website. I would ask you to please turn to our forward-looking statements on slide two. Before we begin, I would like to remind you that any statement made during this call that are not historical are considered to be forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.

Any forward-looking statements represent our views as of today, March 1, 2022 only. A replay of this call will be available on the company's website, www.syndax.com, following this call. With that, I'm pleased to turn the call over to Michael Metzger, Chief Executive Officer of Syndax. Thank you, Maghan, and thank you to everyone joining us on today's call and webcast. Before we turn to the deck, let me start my comments by first welcoming Kate Madigan to Syndax as our new Chief Medical Officer. Kate completed her formal education and training at Dartmouth and USC and has had a distinguished professional career at some of America's most prestigious pharmaceutical firms. We are truly honored to have her joining our team, and you will hear more from her on future calls. I would also like to take this opportunity to thank Michael Myers for his exceptional contributions to Syndax over the past seven years. Michael has flawlessly led the development of both of our programs into their registration trials. Michael is committed to seeing Syndax successfully transition into its next phase of growth, and we are grateful that he will remain an active advisor to the company. Now turning to slide 3. 2021 was a truly transformational year for Syndax. We initiated registration trials for both of our lead programs, SNDX-5613 and axatilimab. We entered into a global partnership and collaboration with a world-class partner, Incyte, on axatilimab to expand the potential for this program. We ended the year with an exceptionally strong balance sheet following a $152 million upfront payment from our collaboration and $81.2 million in net proceeds from our December offering, following strong data disclosures for both of our lead programs at the 2021 American Society of Hematology Medical Conference. Especially given the current challenging market backdrop, we are starting 2022 with an extremely solid balance sheet position. This gives us the resources to expand both of our assets into new indications and the flexibility to aggressively pursue business development opportunities to augment our pipeline with potential best-in-class molecules. Slide four provides a high-level summary of our current corporate priorities as we strive to realize a future in which people with cancer live longer and better than ever before. The momentum is really building at Syndax. Our three pivotal phase II trials for SNDX-5613, our highly selective menin inhibitor, which we call AUGMENT-101 cohorts 2A, 2B, and 2C, is progressing very well and is actively enrolling patients. For axatilimab, our antibody against CSF1R, enrollment is ongoing in our pivotal AGAVE-201 trial, and we are now underway working closely with our new partner, Incyte, to maximize the value of this important program. I wanna emphasize that we now have two registrational programs ongoing for two first-in-class and potentially best-in-class medicines for two areas of important unmet medical need. It is an enormously exciting time for the company as we anticipate filing potentially two NDAs in 2023 and are starting to expand the organization to support the commercial launch of both SNDX-5613 and axatilimab in the United States. Let's now turn to slide 5 and provide further details on where we are with SNDX-5613. First, we have opened three single-arm phase II trials that FDA has agreed may each serve as a pivotal trial. Each of these single-arm phase II trials represent an independent path to a separate indication. AUGMENT-101 Cohort 2A will enroll patients with relapse refractory KMT2A-r ALL. Cohort 2B will enroll patients with relapse refractory KMT2A-r AML, and Cohort 2C will enroll patients with relapse refractory NPM1-AML. Each trial is open to patients aged 1 month or older, and each trial will enroll independent of the other two. We may seek initial regulatory approval for SNDX-5613 based on the results of any one of these trials should one trial enroll faster than the others. Or we may seek initial regulatory approval with any two or all three, just depending on when they complete enrollment. We are happy to report that additional site initiation and patient accrual across the cohorts is going extremely well. We are very optimistic that we'll be able to complete enrollment in at least one of these cohorts this year. Given our current trajectory and our view of the landscape, we anticipate being the first company to achieve regulatory approval for a menin inhibitor. Needless to say, we believe being first to market is extremely important and accretive to the long-term value of Syndax. We have agreement with FDA that for each trial, the primary endpoint will be the percentage of patients achieving CR/CRh, with secondary endpoints including durability of CR/CRh response, transfusion independence, overall survival, and safety. Importantly, the trial design allows patients to be treated with SNDX-5613 after bone marrow transplant, a design feature that allows us to start to understand the role of SNDX-5613 in the post-transplant maintenance setting. We also have agreement with FDA on the statistical design of each trial. Each trial will enroll 64 patients and up to 10 pediatric patients. Finally, we have agreement with FDA that 163 milligrams every 12 hours given with a strong CYP3A4 inhibitor is an appropriate phase II dose, and that is the dose we are using in each of these trials. We know that the vast majority of eligible patients are on a strong CYP3A4 inhibitor, and in an effort to enroll the cohorts as quickly as possible, at least one cohort to complete this year, we have now prioritized the enrollment of these patients versus not, those not on a strong CYP3A4 inhibitor. Once one cohort closes to enrollment, we plan to increasingly focus on accumulating the data required for labeling, which includes the necessary dose adjustment, often referred to as the Arm A dose. Let me remind you that this clinical pharmacology data is not in any way limiting on our ability to enroll and complete the pivotal trial. Beyond the AUGMENT pivotal program in relapsed refractory disease, slide 6 highlights some of the additional opportunities we're exploring with SNDX-5613, all of which build on the excellent safety and efficacy profile we have thus far seen with SNDX-5613. The panel on the left highlights the trial we are planning in collaboration with The Leukemia & Lymphoma Society, otherwise known as LLS. They have selected SNDX-5613 as the first menin inhibitor to be tested as a specific targeted therapy for patients with MLL-r or NPM1 AML in their umbrella trial that they call Beat AML. The collaboration we have agreed to with them will test 5613 in combination with venetoclax and azacitidine in newly diagnosed AML patients who are unfit for induction chemotherapy and will consist of a phase I followed by a phase II/III trial, which could serve as the basis for a regulatory filing. Our scientists have generated preclinical data that supports the benefit of menin inhibition in combination with chemotherapy. Therefore, the middle panel of the slide highlights a trial to explore the use of 5613 in combination with standard salvage chemotherapies used for pediatric patients with ALL or AML that we are calling AUGMENT-102. The panel on the right illustrates a third trial that explores the activity in 5613 in patients with AML who have MRD-positive disease. This trial is being conducted as part of the INTERCEPT master clinical trial being led by the Australasian Leukemia & Lymphoma Group. The INTERCEPT trial is focused on investigating novel therapies to target early relapse and clonal evolution as preemptive therapy in AML. The trial will enroll patients with measurable residual disease progression following initial treatment, a group of patients at very high risk of relapse that represent an important unmet medical need. A general observation in the treatment of cancer is that the earlier in the patient's disease course that you treat, the better patients do and the longer the patients stay on medicine. The INTERCEPT trial is a very creative approach to treating patients early in their disease course. I will also note that 5613 is the first menin inhibitor to be included in the INTERCEPT AML master clinical trial. We believe the selection of SNDX-5613 for inclusion into two master clinical trial protocols highlights the enthusiasm that investigators have shown for treating patients with acute leukemias with SNDX-5613. As mentioned on our last quarterly call, we are excited to expand the clinical opportunities for SNDX-5613 beyond the initial approval in relapsed refractory acute leukemias. Slide seven highlights our goal as a company to be first in market, to market in relapsed refractory disease and then be first to garner additional value-enhancing indications by expanding the use of SNDX-5613 into newly diagnosed and maintenance settings in patients with MLL-r and NPM1 mutant acute leukemias. We see the opportunity to treat patients with these forms of mutant acute leukemia, which account for up to 40% of the eligible patient population, as early in their treatment journey as possible, and then drive them into remission and maintain them in that state for months, if not years. That emerging paradigm for menin inhibition is what will enable this to be one of the most important new franchises in heme malignancies and why we are so keen to invest in SNDX-5613 at this stage. Let me now turn to axatilimab, our potentially best-in-class monoclonal antibody therapy targeting CSF1R. Slide eight is our pivotal trial for axatilimab in cGVHD. This trial is the axatilimab for graft versus host disease trial called AGAVE-201. The trial is enrolling patients with cGVHD whose disease has progressed after two prior therapies. Patients must be at least six years of age and have met overall entry criteria. This is a pivotal dose-ranging trial in which patients will be randomized to one of three treatment groups, each investigating a distinct dose of axatilimab given either every two weeks or every four weeks. The primary endpoint is overall response rate using the 2014 NIH consensus criteria for cGVHD. Secondary endpoints will include duration of response and validated quality of life assessments using the Lee Symptom Scale. Enrollment to the study is going quite well, and we are on track to deliver top-line data in the first half of 2023. We were also delighted to announce during the quarter that Syndax and Incyte closed our global collaboration that brings together two companies with a solid track record of innovation to accelerate and maximize the development of axatilimab. As you know, we presented our phase I/II cGVHD data at ASH in December of last year, which received a very positive reaction and further underscored its best-in-class profile. Through our collaboration, Syndax and Incyte will pursue an expanded set of indications in cGVHD and other fibrotic diseases. The development plan calls for the partners to design novel combinations of axatilimab in Incyte's JAK inhibitors, with a goal of establishing axatilimab in earlier settings within cGVHD and expanding its market opportunity. As we previously mentioned was our intention, Syndax will initiate a robust phase II trial in IPF in the fourth quarter of this year. The first expansion outside of establishing cGVHD into other fibrotic diseases where we believe axatilimab could have a significant impact. Successful development in IPF could lead to an additional approval in a very important indication of considerable value and would provide support to axatilimab in other fibrotic-driven diseases that the parties could explore over the course of the collaboration. Slide nine highlights our view of the broad clinical and commercial opportunity for axatilimab. We believe chronic GVHD represents a high unmet medical need and an important commercial opportunity, with approximately 14,000 patients suffering from cGVHD in the U.S. today. The recent approvals of Jakafi and Kadmon's belumosudil will begin to delineate the commercial opportunity in cGVHD. Despite recent advancements in this area, to our knowledge, axatilimab is the only agent in clinical development that specifically targets the monocyte macrophage lineage. Both Syndax and Incyte believe the data generated to date with axatilimab suggests it has the potential to play an important role in the treatment of cGVHD, both as a monotherapy and, given its safety profile, in combination with complementary medicines such as Jakafi and other JAK inhibitors within the Incyte portfolio. Through combinations in the frontline setting as well as the opportunity to expand to ex-U.S. markets, we envision the cGVHD opportunity more than doubling, as shown on this slide. As we move axatilimab into additional indications, starting with IPF, we really see axatilimab contributing materially to the value of our company moving forward. Finally, slide 10 summarizes the transactions that led to the acquisition of menin, MLL-r, and axatilimab programs. We believe these transactions underscore our robust capabilities to identify and evaluate high-value differentiated ax-assets, as well as the clinical development expertise to bring these compounds through key value inflection points. We anticipate in 2022 that we will be able to continue to expand our pipeline through product acquisitions or in-licensing of quality differentiated assets. We expect to remain among the preferred partners of such transactions. I'll now like to turn the call over to Alex to review our financial results. Alex? Thank you, Michael. Let me now take a few minutes to discuss our financial results for the fourth quarter and the full year of 2021. The results of our operations for the fourth quarter of 2021 and the comparison to the prior year quarter are included in our press release, so I won't repeat them in these remarks. Additional financial details are available in our fourth quarter and full year report on Form 10-K, which will be filed today. I would like to point out that our net profit for the quarter was $96.2 million, or $1.81 per share, compared to our net loss of $20.4 million or $0.44 per share for the same period last year. This difference is primarily attributed to the change in license revenue generated from the collaboration agreement with Incyte. Turning to slide 11. We ended our fourth quarter with $439.9 million in cash and cash equivalents, including net proceeds of approximately $81.2 million from our public offering completed in December 2021, and with 59 million shares and pre-funded warrants outstanding. This cash balance also includes $152 million in proceeds from the December closing of the collaboration agreement with Incyte. Our current cash runway now extends into the second half of 2024 and supports our expanded development and early commercialization plans for both the axatilimab and the menin programs during this period and provides us flexibility for continued business development. Looking ahead, I'd like to provide financial guidance for the first quarter and full year of 2022. For the first quarter of 2022, we expect R&D expense to be $30 million-$35 million and total operating expense to be $38 million-$42 million, including $4 million of non-cash stock compensation expense. For the full year 2022, we expect R&D expense to be $130 million-$140 million, and total operating expense to be $160 million-$170 million, including approximately $14 million of non-cash stock compensation expense. The increase in R&D and operating expense in 2022 compared to the prior year period is driven by the expansion of both axatilimab and menin into registration trials, expansion into new indications, and initiation of pre-launch commercialization activities. This guidance does not currently reflect any potential offset by the cost sharing of axatilimab operating expenses with our partner Incyte, and we will continue to update guidance over the course of the year as we move forward with this collaboration. With that, let me now turn the call back over to Michael. Great. Thanks, Alex. Let me close the call by again noting that this management team has been focused on obtaining regulatory approval for drugs that extend and improve the lives of people with cancer and other diseases, and we consider having two ongoing registration programs to be a major achievement. We are also really excited about the broad franchise opportunities for both programs beyond their initial registration indications. We believe SNDX-5613 could have broad utility across a wide range of clinical settings in acute leukemia and possibly in a number of others as well. Our immediate goal as a company is to be the first to market in relapsed refractory disease and then to garner additional value-enhancing indications by expanding the use of SNDX-5613 into newly diagnosed and maintenance settings in patients with KMT2A-r and NPM1 acute leukemias. Axatilimab also holds the promise of a broad franchise opportunity in various lines of therapy in cGVHD and across a broad range of fibrotic diseases, starting with IPF. We have a strong balance sheet to aggressively advance our programs and achieve key upcoming milestones. We remain optimistic in 2022 that we can continue to identify and bring in novel molecules to deepen our portfolio. We have a proven track record of delivering on this pillar of our corporate strategy, and I believe this is a core strength of our company. We could not accomplish all that we have without our wonderfully talented team here at Syndax, our collaborators, and most importantly, the patients, trial sites, and investigators involved with our clinical programs. In addition, I would like to thank our committed long-term investors who are helping us build this great company. With that, I would like to open the call for questions. As a reminder, to ask a question, you will need to press star one on your telephone. To withdraw your question, press the pound key. Please stand by while we compile our Q&A roster. Our first question comes from Phil Nadeau with Cowen and Company. Please proceed. Good afternoon. Thanks for taking my questions, and congrats on a very productive year. First, a question on the SNDX-5613 non-CYP3A4 dose. I wanna make sure I understand the strategy. It sounds like you're saying patients who are not on a CYP3A4 inhibitor probably won't be enrolled in the trial for some time, but that's okay because you just simply need to identify the dose through pharmacokinetic measures and actually having clinical data from patients who aren't on CYP3A4 inhibitors is less of a requirement for filing. Is that correct? Yeah, maybe I'll start and Briggs can comment also. Phil, thanks for the question. Look, I think the priority, as we've seen, most of the patients seem to be on strong CYP3A4 inhibitors, antifungals, and our priority is to get the trial enrolled, each of the cohorts enrolled as quickly as possible. As a result of the dynamics of what I just described, we're prioritizing getting it done versus collecting all the clin pharm information in this, you know, in this trial. We are seeing some patients that have, you know, that are not on a strong CYP3A4 inhibitor, but the cadence of that is not. We're not prioritizing putting them on the trial versus, you know, getting as many patients in as we can, to complete it, you know, as early as we can. I think what you said was correct. I think we wanna get the information together, the clin pharm information together in order to, you know, complete the trial, ultimately complete the trial for labeling purposes. That's, you know, once we submit the NDA. That's, you know, once we have one of the cohorts fully enrolled, we'll turn our attention to bringing more of those patients in. They're just harder to find. Got it. Okay. Have you identified a dose yet, or are there complications in figuring out what dose should be the dose that is ultimately submitted? No, there's been no trouble identifying a dose. I think it's just a matter of, you know, accumulating more patients, that's all. Got it. Okay. As you know, we have identified, you know, two doses that meet the RP2D as part of the phase I. You know, we've identified active doses. It's just a matter of, you know, putting on enough patients who are not on a strong CYP3A4 inhibitor. that's put enough patients on in order to figure out the dose that you wanna register ultimately? Correct. Well, what PK matches our RNB dose? Perfect. Yep. Okay, that's very helpful. Second question also on the pivotal trials. In terms of the pace of enrollment, I think in the past you've said KMT2A-r AML patients that group is likely to enroll more quickly 'cause of the competing trials. Is that still your expectation? Is that the cohort that we should expect to see data from first? Yeah, I think we said, Phil, that the AML cohorts, we didn't differentiate between KMT2A-r and NPM1. We just said that our expectation is the NPM1 AML cohorts will enroll faster than ALL cohorts. As I said in my remarks, we expect to enroll at least one, maybe two, hopefully this year fully. We're not saying exactly which ones will enroll faster than the others, but that was the kind of guidance we had given, and we're sticking with that. Perfect. Last question on axatilimab. You referenced the two recent approvals and the fact that those launches could inform you about the GVHD market. We're curious what you expect to learn most from those launches. You know, aside from the revenue trajectory, which we'll all see, but in terms of like location of patients, access to reimbursement, desire to be treated, what do you think will be most informative about those launches as you contemplate axatilimab's commercialization? Yeah, maybe I'll ask Anjali, our Chief Business Officer, to comment on that. Sure. Thanks, Michael, and thanks, Phil, for the question. I think, you know, a big part of the launches too is the awareness of new drugs in this space because for so long it's been dominated by generic entry and, the defining of a treatment algorithm for, chronic GVHD, I think is an ongoing and evolving, event. That alone I think is really helpful for the space and for, you know, being able to position axatilimab within the treatment algorithm when it is approved in, we're hoping the 2024 timeframe. You know, beyond the items that you mentioned, reimbursement, pricing, adoption, you know, understanding who are the physicians that are likely to be the, decision makers or key influencers in this space and, early adopters will also be very helpful. I think even building awareness of these new drugs and agents and how they can help patients is also part of the process that we're watching. Perfect. Thanks for taking our questions and congrats again on the progress. Thanks, Phil. Thank you. Our next question comes from Bert Hazlett of BTIG. Please proceed. Hi. Thank you, and thanks for taking my question. Just with regard to SNDX-5613 and the expanded opportunities, in particular the matched protocol trials, Beat AML and INTERCEPT, could you just give a little bit more granularity about, you know, with regard to timing and when we might get a sense of initial data for really any of those studies including AUGMENT-102? Yeah. Thanks, Bert. Thanks for the question. Maybe I'll ask Briggs, Dr. Briggs Morrison to comment on this as well. Hey, Bert. Thanks for the question. All three of those trials will be starting in the first half of this year. Again, for each of them, for the first two, the LLS trial and the combination chemotherapy trial, there's really a phase I portion to pick a dose. And the data that is used to support the dose, you know, could be available, let's say, for Beat AML, early part of next year, potentially also for 702. INTERCEPT is not a combination trial. It's just monotherapy. It's really a question of when we'll have some early data on converting MRD positive to MRD negative. Again, I would think, perhaps by middle of next year there might be something. Okay. Terrific. Just shifting gears to axatilimab for a question. With regard to the IPF study, could you provide any more granularity on the phase II effort there? I know it's early days, but would very much love to understand a little bit more of the scale and scope of the work there. Yeah, sure. Thanks, Bert. Maybe I'll ask Briggs to comment a little bit more on that as well. Yeah. Bert, we'll give a lot of details as we typically do once we have FDA endorsement on the trial and we're sort of opening the trial. I would say our general approach that we've been advised by experts in the field is that if you're gonna study IPF, then you just have to study IPF and you have to do you know an endpoint FVC endpoint-driven trial that's about a year in duration. That's you know the sample size and some of the details we'll go through with you after we get endorsement and we're up and running the trial. You should think of it as you know a year-long trial with FVC as the primary endpoint. We've looked at a talk with many experts about sort of surrogate biomarkers that you could use. You know, to sort of do an intermediate time point, and the advice that we've gotten is that none of those have really been well-validated, and they're maybe just as high a false positive as a false negative. The best thing to do is if you really believe that you have an active agent, just go ahead and do the full one-year trial. That's the current thinking, but we'll give you a lot more details once we open up the trial. Okay, great. Just one big picture question. You've had some intriguing success with the licensing of 5613 and axatilimab. Is there a common theme here with regard to therapeutic area, oncology, fibrotic disease? You know, you've again had some unique success. How are you thinking about additional business development efforts more broadly? Yeah, thanks. Thanks for that question too, Bert. You know, look, I think the theme for us has been identifying molecules that are sort of, we think, best-in-class differentiated molecules. We have never sort of drawn a line, saying that, you know, they're heme versus solid tumor, or one modality versus the other. I think we're most interested in targeted therapy for oncology. Having said that, I think we are, you know, really looking for molecules at a time point in their development, usually generally on the earlier side, you know, late preclinical, early clinical, where, you know, we can use our expertise in terms of clinical development, translational medicine in order to make a big difference with these molecules. I think the, you know, right now we are on the heme side of the equation, in terms of what we're developing. There is some synergy between call points between our molecules, which is great. I wouldn't rule out a broader kind of opportunity set within oncology, you know, maybe perhaps in solid tumors as well. As you know, it's a competitive field and it's hard enough to find molecules that you feel are worthy of resources and the team's time. We're hunting hard, and we expect we'll be able to identify hopefully one or more molecules this year and continue building the pipeline. Terrific. Thanks for the call. I look forward to more progress. Thank you. Thank you, Bert. Thank you. Our next question comes from Yigal Nochomovitz of Citi. Please proceed. Hi, team. This is Asher Mubarak on for Yigal. Thanks for taking my question. Congrats on all the progress. I guess, can you talk a little bit about the ex-U.S. opportunity for SNDX-5613? Do you think the expansion cohort data may be sufficient for a filing there as well, or perhaps you'll need another control study? Also just curious about how the Beat AML cohorts might play into a European strategy. Thanks. Yeah. Maybe I'll ask Briggs to comment on our European strategy as well for... Then I took it to mean not a, not necessarily a commercial opportunity, but you were thinking more in terms of trial in development, correct? Correct. Thanks, Asher. Briggs? Yeah. Yeah. Great. Thanks so much for the question. Your instincts are quite right here that, you know, the regulatory environment in Europe is different, and so the single arm, so-called palliative trial with CR/CRh and durability may not be enough, but it may. We're in, you know, discussions with regulators about what it'll take to get the drug approved in the EU. I think your point about Beat AML, since that is as we move into the randomized phase II portion, that is a randomized trial with sort of standard of care as the control arm, so that could play into it. But I would say, you know, stay tuned for more information on the European strategy. It will be different from the U.S. Okay, great. That makes a lot of sense. I guess, is there any color you can share on maybe the status of the axatilimab JAK inhibitor combo? Yeah. Thanks for the question. As I said in my remarks, we have kicked off our collaboration with Incyte, and I think we're in the design phase of putting those trials together. We'll have more to say on future calls. We hope one or more trials are initiated this year in combination with one or more of their JAK inhibitors. We haven't specified, they haven't specified as to which ones as of yet, but stay tuned. Okay, great. Thank you very much. Thank you. Thank you. Our next question comes from Justin Walsh of B. Riley Securities. Please proceed. Hi. Thank you for taking the questions. I know that Beat AML has a pivotal portion, but I was wondering if you can provide some comments on how AUGMENT-101 or AUGMENT-102 and INTERCEPT could lead to label expansions. Specifically, do you think that the data for these trials could support an expansion on their own or maybe just inform the design of larger trials? Yeah. Thanks for the question, Justin. I'll turn it to Briggs once again. No, Justin, I think the second two are more to inform future trials. It's getting a dose for the combination with chemotherapy in the refractory setting. I think INTERCEPT will give us a sense of what the MRD positive to MRD negative conversion rate is, which will allow us to power our definitive trial. Got it. Thanks. One more question for me. You mentioned potential benefits of being first to market with a novel drug. It's pretty obvious, but can you maybe provide some color on how you plan to lay the groundwork to take maximum advantage of this? And, sort of related to that, any thoughts on any potential label differences between your asset and any fast follower menin and MLL-r inhibitors that could come to the market? Yeah. Thanks, Justin. Great questions. In terms of label differences, I think it's a little early. I'll just take that question first. It's a little early to be speculating about label and how our molecule may be different than our competitors. I think at this stage, we're the only ones that have really shown much data in the clinical setting. I think we need to kinda wait and see what others show and how our drug continues to develop. Needless to say, I think we're in a very favorable position. In terms of seizing the opportunity to expand, I think we made comments, and then I think you've become accustomed to hearing about the different trials we're doing in the frontline and the maintenance setting. I think strategy here is obviously to get the drug approved in relapsed refractory disease, expand into the frontline setting in combinations. I think what's very nice about our molecule is that you could add our drug onto regimen. We hope to be able to add it onto regimens that already exist, you know, to be able to accommodate the KMT2A-r or NPM1 mutation types. You know, the opportunity to add to the frontline in the frontline setting and then recapture patients in the maintenance setting and perhaps keep them on drug for, you know, a long period of time in order to keep their disease at bay. That's a vision we have for this molecule. We're gonna continue to do those trials and look at combinations that position us both in the, you know, unfit frontline setting, maybe the fit as well, and then move in parallel into the maintenance setting. I'll also note that one important feature of the phase II pivotal trials that we're running now is that patients can go back on therapy after going through stem cell transplant, and that will be an opportunity to see, you know, how patients do in the, call it, maintenance setting. Although we'll have to run, and I think we said before, we'll be running additional maintenance trials. It will give us an early look into, you know, how patients do post-transplant and perhaps give an indication of how long they can actually stay on treatment, which we expect to be, you know, we hope quite a long period of time. I think that's a general landscape of how we'll be approaching. Great. Thanks for taking the questions. Thank you, Justin. Thank you. Our next question comes from Joel Beatty of Baird. Please proceed. Hi. Thanks for taking the questions. First one is on the registrational trial of SNDX-5613. Just to clarify, what happens now when a patient screens for enrollment but is not on a CYP3A4? They're allowed to be admitted to the trial. Thanks, Joel, for the question. They're allowed to be admitted to the trial. I think that there's no change to that. I think the point being that we're not holding spots for patients who are not on a strong CYP3A4 inhibitor. In fact, we're enrolling, you know, almost on a first come, first serve basis. It just so happens that the vast majority of patients are on a strong CYP3A4 inhibitor. You know, I think the idea is that it might be a little bit slower to enroll patients who are not on a strong CYP3A4 inhibitor in the scheme of this trial, and that's what I meant by my remarks. We're not prioritizing them versus others who are on a strong CYP3A4 inhibitor. There is in no way an impact on our ability to complete the trial. It's more of a submission issue and a labeling issue for dose adjustment that we're gonna have to, you know, figure out in the course of the next while as the trial continues what those clin pharm questions and answers are. That's the kinda long-winded answer to your question. Got it. Appreciate that. Makes sense. For axatilimab, how much dose finding work needs to be done for the IPF setting versus jumping right into a more robust study of efficacy? Yeah, that's a great question. Maybe I'll ask Briggs to comment there. Yeah. Thanks, Joel. The current thinking, which again we'll have to validate with the FDA when we finalize the protocol, is that we would not do dose ranging in the IPF trial. We would take a dose that we think gives us maximal pharmacodynamic effect. As you know, in AGAVE-201, there are three different arms, the 0.3, the one, and then the three every four weeks. The one mg per kg, as you saw, in our ASH data, looks like a very, very good dose. It gives us optimal PK/PD, very good efficacy. The current thinking is that we would not do dose ranging, we would just simply do a proof of concept trial at roughly that dose. Again, we'll say more about that once we have that finalized. Our view is that's a really good dose to be able to test the concept. Obviously, if the trial is positive, there may need to be similar to AGAVE-201, some additional, the regulators may want some dose ranging, but I think for us it's a proof of concept trial where we just take one dose. Great. Thank you. Thank you, Joel. Thank you. Our next question comes from Peter Lawson of Barclays. Please proceed. Thanks for taking the questions. Thanks for all the updates. Just around the CYP3A4 strong, weak arms, how many would you need? How many patients would you need that aren't on a strong CYP3A4 inhibitor for a filing? Yeah, maybe I'll ask Briggs. Thank you for the question, Peter. Let me ask Briggs to answer that. Right. Peter, the question is, you know, how many patients worth of data at a dose that we feel comfortable saying that there is sufficient PK to, you know, label. We think it's probably in the, you know, let's call it 12-15 range of not on a strong CYP3A4 inhibitor and then a separate group that's on a moderate, as Michael pointed out. The pivotal trial, at this stage, they'll all be on a strong inhibitor, so it's a question of probably in the 12-15 should give us enough understanding of the PK to be able to inform the dose. Okay. How's that tracking? Is that significantly behind? Well, right. Yeah. As Michael said, I think our decision was that we're prioritizing the enrollment of the registration trial. The main reason to prioritize enrollment of the registration trial is so that we have good durability data, right? Because once we finish enrolling all of those patients, then it's six months after the last patient is when we do the data cut, and we'd like to have, you know, as much durability as possible for labeling purposes. At this point, the decision is put people on who are on a strong CYP3A4 inhibitor, and don't worry about the non or the moderates. Once at least one cohort is fully enrolled, then that patient population where we've already fully enrolled, we will then enroll additional patients with the non or moderate. I'm not sure if it's to your question, if it's ahead or behind, but we've made a strategic decision that we're gonna prioritize getting everybody in onto the pivotal trial, 'cause that'll allow us to get the durability that we need. Gotcha. Thank you. Would physicians have a problem, I guess, putting a patient on a strong CYP3A4 inhibitor even if they didn't require it, so you kind of had a, almost like a label- No. Right. you had. That's right. Right now, actually, there are patients who come into the trial who are not on a strong in order to get onto the trial right now, they need to be on a strong, so the physician just switches them. There, it's actually not that many. Most of the patients, whatever the voriconazole, posaconazole seem to be the preferred agents anyhow. Most patients are already on a strong CYP3A4 inhibitor. Every physician we've talked to, every investigator on the trial has said, "Well, they need to be on a strong inhibitor to go on. I'll put them on a strong inhibitor. Not a problem. Perfect. Thank you. Just kind of a final question around the strong, weak CYP3A4. The Beat AML, the AUGMENT-101, the AUGMENT-102 and the INTERCEPT, does that have a requirement or will it have a requirement for a strong CYP3A4 inhibitor? Right. For Beat AML and 702 right now, again, because the dose that we have agreement with the FDA is with a strong inhibitor, those patients will be on. Again, that's standard of care in those populations, because they're, you know, similarly get put on antifungals. In the INTERCEPT trial, it's not a requirement that they be on a strong CYP3A4 inhibitor, that these are patients who are in morphologic remission, and so they actually don't necessarily need an azole. That one, you know, where there's an option to be on the trial without being on a strong inhibitor. Great. Okay. Thanks so much. Thanks for all the details. Thank you, Peter. Thank you. I would now like to turn it back to Michael Metzger for closing remarks. Great. Thank you, Didi. Thank you, and thank you to everybody who participated on the call today. We look forward to seeing many of you at the upcoming conferences in March. I know there are a handful of those and with that, I wish you all a very, very nice evening.
