With that, I'm pleased to turn the call over to Michael Metzger, Chief Executive Officer, Syndax. Thank you, Sharon, thank you to all of you joining on the webcast today. Now, turning to slide three. 2022 was a year of growth and strong execution for Syndax. We made great progress working towards our long-term goals, all of which put us firmly on the path to becoming a fully integrated commercial stage biopharmaceutical company, delivering two best-in-class products to patients in areas of high unmet medical need. On revumenib, we made significant progress enrolling patients in the AUGMENT-101 pivotal trials, announced breakthrough therapy designation for patients with relapsed refractory KMT2A rearranged acute leukemia, and presented robust updated phase 1 data that further supported revumenib's best-in-class clinical profile in two oral sessions at the 2022 American Society of Hematology Annual Meeting. We initiated additional phase I trials designed to test revumenib in a variety of settings, including combinations with standard of care regimens. For axatilimab, we completed enrollment in the pivotal AGAVE-201 trial, published the initial phase I/II chronic graft-versus-host disease dataset in the Journal of Clinical Oncology, and made progress expanding the axatilimab development program in collaboration with our partner, Incyte. We are fortunate to have Incyte as a strong collaborator to help us successfully advance axatilimab's development. In December, we bolstered our balance sheet with a $172.5 million follow-on offering. Our cash runway is now expected to extend into the second half of 2025, allowing us to appropriately invest to maximize the value of our pipeline, prepare for two potential U.S. commercial launches in 2024, and pursue potential business development opportunities. Our focus, determination, and unending commitment to patients has propelled us forward to this critical year, a year that we expect will be marked by pivotal readouts and registration filings for our two lead drug candidates, both of which are first and potentially best-in-class treatments. 2023 is an incredibly significant year for Syndax, I'm confident that we have the expertise and resources to execute on our goals, along with the determination to realize a future in which people with cancer live longer and better than ever before. Turning to slide four, we provide a high-level summary of our current corporate priorities. Starting with revumenib, our highly selective menin inhibitor. Our pivotal phase II AUGMENT-101 trial, evaluating revumenib in patients with relapsed refractory NPM1 mutant or KMT2A rearranged acute leukemia, is progressing well. We are happy to report that we have completed enrollment of a sufficient number of patients with a KMT2A rearrangement to support a registration filing, and we are on track to report top-line data from the trial in the third quarter of 2023. This data would provide the basis for an NDA filing by year-end 2023. I will provide more details on AUGMENT-101 later in the call. In addition to the AUGMENT-101 trial, we have ongoing trials testing revumenib in the earlier lines of therapy and in combination with standard of care medicines to treat these forms of acute leukemia. We are committed to unlocking the full potential of this important therapy. With that goal in mind, we expect to have several additional data readouts in 2023 for revumenib. These include initial top-line data from AUGMENT-102 chemo combination trial in relapsed refractory acute leukemia patients, safety data from the dose escalation phase of the Beat AML cooperative trial of revumenib in combination with venetoclax and azacitidine in newly diagnosed AML patients, and initial top-line data from the first solid tumor proof-of-concept trial in metastatic colorectal cancer. Moving to axatilimab, our antibody against CSF1R. We remain on track to report top line data in mid 2023 from the pivotal phase II AGAVE-201 trial evaluating axatilimab in patients with chronic graft-versus-host disease, or cGVHD, and plan to submit a BLA filing by the end of 2023. To maximize the value of the axatilimab program, we anticipate initiating additional trials in 2023, including a combination of axatilimab and ruxolitinib in frontline cGVHD that we expect Incyte to be in later this year, as well as a phase II trial of axatilimab in idiopathic pulmonary fibrosis, or IPF, that we anticipate kicking off in the first half of 2023. We continue to evaluate potential opportunities to in-license earlier stage targeted oncology compounds that we believe could become high value differentiated assets. Our bar for doing so is quite high, as any compound would need to complement our current pipeline and fit in with our long-term corporate strategy. I'll provide further details on the revumenib program. As you recall, the phase II portion of AUGMENT-101 is designed as three single arm pivotal trials with distinct patient populations that enroll independently. These patient populations are KMT2A rearranged ALL, KMT2A rearranged AML, and NPM1 mutant AML. The primary endpoint of each pivotal trial is the% of patients achieving CR/CRh, with secondary endpoints including durability of CR/CRh response, transfusion independence, overall survival, and safety. In December, we received breakthrough therapy designation, or BTD, for revumenib for the treatment of all adult and pediatric patients with relapsed or refractory KMT2A rearranged acute leukemia, whether presenting as acute myeloid or acute lymphoid phenotype. The receipt of BTD underscores the potential, if approved, for revumenib to be the first drug to address the breadth of unmet medical needs in KMT2AR leukemia, accounting for up to 10% of all acute leukemias. Based on the broad breakthrough therapy designation and our ongoing conversations with regulators, we will pool the data generated from both the AML and ALL KMT2AR cohorts into a single NDA filing aimed at an indication to treat all relapsed refractory acute leukemia patients with a KMT2A rearrangement. Thanks to the enthusiastic support of our investigators, we have already enrolled a sufficient number of patients with KMT2A rearrangements in the phase II portion of the AUGMENT-101 trial to enable this filing strategy. We expect to share top-line data from this population in the third quarter and file an NDA for the treatment of relapsed refractory KMT2AR acute leukemia in adult and pediatric patients by the end of 2023. Separately, we continue to enroll relapsed refractory NPM1 mutant AML patients and expect to report completion of enrollment for these patients in the second half of 2023. These trials are enrolling well, and there was significant excitement for revumenib by investigators at the ASH Annual Meeting in December, where we presented updated phase I data that Briggs will take you through on slide six. Briggs? All right. Thank you so much, Michael. As many of you know, at the ASH Annual Meeting in December of last year, Doctor Ghayas Issa from the MD Anderson Cancer Center presented updated results from the phase 1 portion of the AUGMENT-101 trial in two oral presentations. Of the 60 patients evaluable for efficacy in the phase I portion, 30% attained a CR/CRh. Notably, in patients treated at the recommended phase II dose, CR/CRh was the same in both KMT2AR and NPM1 subsets at 27%. The median duration of CR/CRh response was impressive in this very advanced patient population at 9.1 months. There was a high MRD negativity rate of 78% among patients achieving a CR/CRh, which is very meaningful in this patient population as it enables patients to proceed to potentially curative bone marrow transplant. We also reported compelling data on 12 patients who achieved a response on revumenib treatment and then went on to receive a stem cell transplant. Additionally, three transplant patients who were treated with revumenib maintenance therapy in the compassionate use setting following stem cell transplant or non-myeloablative stem cell boost, two of whom remained in remission for over a year as of the data cutoff. As a reminder, in the pivotal trial, patients can be restarted on revumenib after bone marrow transplant, a design feature that provides data on the potential role of revumenib in the post-transplant maintenance setting. Revumenib continues to be well-tolerated, and there have been no discontinuations due to treatment-related adverse events. As you look across the development landscape, we believe the data continue to support revumenib's compelling clinical profile and position it as not only first-in-class, but a best-in-class treatment. I'll now turn it back over to Michael. Great. Thanks, Briggs. Turning to slide seven. Given the compelling clinical and safety profile we have observed with revumenib, our clinical development plan seeks to expand its use beyond relapsed or refractory setting into earlier settings and in combination with approved therapies. Here we highlight our ongoing trials of revumenib across the full treatment landscape. Starting with the p hase I Beat AML umbrella trial. As part of our collaboration with The Leukemia & Lymphoma Society, revumenib is being combined with venetoclax and azacitidine to treat newly diagnosed AML patients with an NPM1 mutation or KMT2A rearrangement who are unfit for induction chemotherapy. Revumenib is the first menin inhibitor to be included in the trial, which will assess safety as well as initial efficacy. Enrollment is ongoing, and we expect initial safety data from this trial to be available in 2023. Longer term, we expect that positive Beat AML trial results could lead to a phase II /III trial, which could serve as the basis for a future regulatory filing. We are also currently enrolling patients in the AUGMENT-102 trial, designed to assess revumenib in combination with standard salvage chemotherapies for patients with relapsed or refractory NPM1 mutant or KMT2A rearranged acute leukemias. We also expect to have initial data available from this trial in 2023. Finally, the INTERCEPT trial. This trial was recently initiated as part of the INTERCEPT master clinical trial led by the Australasian Leukaemia & Lymphoma Group. This trial is a creative approach to treating patients early in their disease course, as it is focused on investigating novel therapies to target early relapse and clonal evolution as preemptive therapy in AML. It is designed to explore the activity of revumenib, the first menin inhibitor to be included as monotherapy in patients with AML who have MRD-positive disease following initial treatment, a group of patients at very high risk of relapse. We are also in the process of planning a trial in combination with standard of care intensive chemotherapy used to treat fit patients in the frontline setting. We plan to initiate that study in the second half of this year. As is detailed on slide eight, unlocking the full potential of revumenib beyond the relapse refractory acute leukemia setting by moving it earlier in treatment and in combination with other approved agents, has the potential to add meaningful value both for our shareholders and, even more importantly, for patients in need. With these expansion opportunities, we see the potential to address upwards of 12,000 NPM1 mutant and KMT2A acute leukemia patients across various settings. These two forms of acute leukemia together represent up to 40% of the overall AML population, which to our knowledge will be the largest subpopulation of AML to be addressed by new targeted therapies. There are currently no FDA-approved therapies targeting KMT2A or NPM1 acute leukemias. We anticipate that revumenib could become the backbone of choice for patients with KMT2AR and NPM1 mutant acute leukemias. We are also looking to explore revumenib as a treatment in solid tumors based on the compelling preclinical science supporting the role of the menin-MLL1 interaction in beta-catenin-driven tumors. A proof of concept signal seeking phase I clinical trial in colorectal cancer is open for enrollment. We expect to report top-line data by year-end 2023. Let me now turn to axatilimab, our potentially best-in-class monoclonal antibody therapy targeting the CSF-1 receptor that has the potential to serve as an effective practice-changing intervention in this underserved population. Slide nine provides an overview of the pivotal AGAVE-201 dose-ranging trial evaluating axatilimab in patients with cGVHD. The trial has completed enrollment of 240 patients whose disease has progressed after two prior therapies, were at least two years of age, and have met overall entry criteria. Patients were randomized to one of three treatment groups, each investigating a distinct dose of axatilimab given either every once or every two weeks or once every four weeks. The primary endpoint is overall response rate using the 2014 NIH consensus criteria for cGVHD, while secondary endpoints include duration of response and validated quality of life assessments using the Modified Lee Symptom Scale. We continue to expect to report top-line data from the AGAVE-201 trial in mid 2023. Per the terms of our collaboration agreement, Incyte will be leading the regulatory filing in cGVHD, which we expect will occur in the later part of 2023. Slide 10 details the results from the phase I/II trial, which showed axatilimab's ability to provide meaningful clinical responses in chronic GVHD patients that have been refractory to multiple prior therapies. This data was presented at the 2021 ASH A nnual Meeting and subsequently published in the Journal of Clinical Oncology in December. These data were well-received among thought leaders who recognized axatilimab as having a clinical profile that would be of benefit in the treatment of these heavily pretreated patients. The overall response rate in the trial was 68%, and the median time on treatment was over 6 months. The overall response rate in the phase II portion was 82%, and the median time to response was rapid at four weeks. Importantly, clinical responses were accompanied by a reduction in the cGVHD symptom burden and improvements in all cGVHD involved organ systems. Additionally, more than half of the responders reduced their use of steroids. Axatilimab demonstrated a favorable safety profile in this refractory population, with the most common adverse events consistent with on-target effects of CSF1R inhibition. Slide 11 highlights the broad clinical and commercial opportunity for axatilimab. cGVHD represents a high unmet medical need and an important commercial opportunity with approximately 14,000 patients suffering from cGVHD in the U.S. today. We 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 monotherapy and given a safety profile in combination with complementary medicines. In collaboration with Incyte, we are enthusiastic about expanding the axatilimab program into frontline cGVHD in combination with ruxolitinib, and we expect a phase I combination trial in patients with newly diagnosed cGVHD to begin later in 2023. The successful commercial launches of Incyte's Jakafi and Sanofi's Rezurock are encouraging, both posting meaningful early revenues that begin to speak to the commercial opportunity in cGVHD. Axatilimab has a differentiated mechanism of action from these products and could potentially offer a unique set of benefits to patients once approved. Beyond cGVHD, we are excited about the opportunity to expand axatilimab into fibrotic diseases where the monocyte macrophage-based lineage plays a key role. We expect to initiate a robust phase II trial in IPF in the first half of 2023. If successful, we believe this trial, along with one additional phase III trial, could form the basis for FDA approval for the treatment of IPF. Through combinations in the frontline setting, as well as the opportunity to expand to ex-US markets, we envision the cGVHD opportunity growing meaningfully. I will now turn the call over to Keith to review our financial results. Thank you, Michael. Let me take a few minutes to discuss our financial results for the fourth quarter and full year 2022. Turning to slide 12. The results of our operations for the fourth quarter of 2022 and the comparison to the prior year's quarter are included in our press release. I will not repeat them in these remarks. Additional financial details are available in our fourth quarter and full year report, which was filed earlier this afternoon on Form 10-K. I'd like to point out that our net loss for the fourth quarter was $39.2 million or $0.62 per share, compared to a net gain of $96.2 million or $1.81 per share for the same period last year. This difference is primarily attributed to the recognition of the upfront payment from Incyte related to the axatilimab collaboration, which we entered into in December of 2021. For the full year of 2022, our net loss was $149.3 million or $2.46 per share, compared to a net gain of $24.9 million or $0.48 per share for the same period last year. The difference is largely due to the upfront payment in December 2021 from Incyte. We ended the fourth quarter with $481.3 million in cash equivalent in marketable securities, including the net proceeds of $162 million from our follow-on offering completed in December of 2022, and 69.3 million shares in pre-funded warrants outstanding. Our current cash is expected to provide a runway into the second half of 2025 and covers our aggressive development and pre-commercialization plans for both the revumenib and axatilimab programs, as well as provides us flexibility should we decide to selectively engage in early-stage business development. Looking ahead, I'd like to provide financial guidance for the first quarter and full year of 2023. For the first quarter of 2023, we expect research and development expenses to be $30 million-$35 million and total operating expenses to be $40 million-$45 million. For the full year of 2023, the company expects research and development expenses to be between $160 million-$175 million and total operating expenses to be $225 million-$240 million, including approximately $30 million of non-cash stock compensation expense. With that, let me now turn the call back over to Michael. Thank you, Keith. As you've heard during the call, 2022 was an exceptional year of growth and execution, but it represents only the beginning of what Syndax aims to accomplish in the near future. With two pivotal trial readouts and potential registration filings in 2023 for our two lead drug candidates, both of which are first and potentially best-in-class treatments, Syndax is at the beginning of a significant transition into a fully integrated biopharmaceutical company, serving multiple patient populations of high unmet medical need. In addition, both programs offer the potential for broad franchise opportunities beyond their initial registration indications, adding to Syndax's long-term growth potential. We have ambitious goals and milestones that I've set out for 2023, I'm confident that we have the right plan and team in place to execute on them. Further, we are in a strong financial position with a balance sheet that allows us to deliver on key near-term milestones. As always, I wanna express our deep appreciation to the Syndax team, collaborators, and most importantly, the patients, trial sites, and investigators involved with our clinical programs. It is all of you who help us to execute on a mission of realizing a future in which people with cancer live longer and better than ever before. I'd also like to thank our committed long-term investors who continue to share in our vision and support us in building Syndax. With that, I'll turn it back over to the operator and open the call for questions. Thank you. At this time, if you would like to ask a question, please press the star and one on your touch tone phone. You may remove yourself from the queue by pressing star and two. Once again, to ask a question, please press the star and one. We'll take our first question from Madhu Kumar with Goldman Sachs. Your line is open. Hi, this is Omari on for Madhu. Our first question is, does the FDA now consider KMT2A rearranged AML and ALL one cohort for filing purposes? Second, what are you looking to see from the two different combo studies of revumenib? Yeah, Omari, thank you for the question. Yes, I think the answer to the first question, which is does the FDA, as far as I heard this, does the FDA consider the one cohort for the filing purposes for KMT2A? The answer is yes. We'll be combining both AML and ALL cohorts, pooling the patients and filing them together. That's the plan. The second question, I'm sorry, you cut out on the second half of it, so I couldn't hear it. Could you repeat that, please? Sure. The second question, what are you looking to see from two different combo studies at revumenib? Once again, it cut out. I think you said, what are we looking to see from the two studies? Is that correct? Right. From the two combination studies for revumenib. Gotcha. The combination studies, we have multiple combination studies ongoing. There's AUGMENT-102, which is a chemo combo, which we'll have data on, we expect, later in the year. We have frontline trials going with Vidaza, with Beat AML. We'll be designing other trials in addition to that in the frontline setting. I think we haven't necessarily set out guidance on what we're looking to achieve. I think these are early studies, where we're gonna be looking at first, of course, safety and early efficacy, and trying to establish a recommended phase II dose. I think that would be, you know, that would be the main objective of those trials, which we'll hopefully achieve by the end of this year. Great. Sounds good. Thanks for taking my questions. Thank you. Our next question comes from Phil Nadeau with TD Cowen. Your line is open. Good afternoon. Congrats on progress, thanks for taking our questions. First, a follow-up on the KMT2A population. For the readout from the 101 trial, it sounds like both AML and ALL patients will be commingled in, I guess now it's a combined cohort. Will the CRc rate be analyzed regardless of myeloid versus lymphocytic etiology, or will there be any stratification for the underlying disease? Yeah, thanks for the question, Phil. Maybe I'll let Briggs answer that question. Yeah. Phil, you may recall that when we announced the breakthrough therapy designation, and back to Omari's first question, the agency did accept that KMT2A rearranged leukemia is one disease, whether it presents as AML or ALL, adults or kids. Part of the support for that was that the data we presented was a combination of AML and ALL, adults and peds. We did break it out, and we will break it out for the agency to further support that designation. The analysis is, we're looking at that integrated population altogether. Got it. Okay. In terms of the patient numbers necessary, I know you've already recruited them. Is the number of patients equivalent to what we thought you were gonna enroll in cohort 2A and 2B in the study? Because they're now being combined, is the required number of patients actually equivalent to just really one cohort worth of patients? Yeah. Phil, thanks for the follow-up. I think we haven't really guided, and we're not planning to guide on the specific number of patients in the combined cohorts. I think what we've said is that it's a sufficient number based on both EOP2 and agency feedback. We feel that we're aligned on a strategy to have a sufficient number of patients that will constitute a filing in the by the end of the year. We'll have that data, of course, in the third quarter. but we're, you know, at this point, we're not guiding specifically to how many patients are in the pooled analysis. Got it. Okay. Last question on revumenib before one question on axatilimab. In the NPM1 pivotal same data, or sorry, the enrollment completion in the second half of the year, that seems to suggest data first half of 2024, maybe mid-2024, based on your prior guidance for the KMT2A population. Is that a fair assessment, or is there some reason why there could be a longer interval between enrollment completion and data in the NPM1 patients? Thanks for that, Phil. I think the same rules apply. I think we said we'd follow patients for six months. We're not being specific as to exactly when in the second half we'll have the NPM1 enrolled. You know, I'm gonna be a little bit conservative and not project out when we'll have top-line data yet in 2024. I think we, you know, it's the same rules that apply to the KMT2A populations as the NPM1. We follow them out for, you know, for six months. Great. Then last question from us on axatilimab. Would you be willing to provide any additional details on the IPF phase II now, or, will we have to wait until the trial's underway? Yeah. Thanks. Thanks for the question, Phil. We were excited to obviously get that trial started, and we'll probably share more details on the trial and the design as, you know, once we're underway. I think that's probably all I'll say for now. Okay, great. Thank you. Thanks, Phil. Our next question comes from Anupam Rama with JPMorgan. Your line is open. Hi, this is Priyanka on for Anupam Rama. Just a quick question from us. Between the two KMT2A cohorts, could you provide any color or clarity on enrollment breakdown? Yeah. Thank you for the question. As I said previously, we're not gonna give specific guidance on how many patients were contributed from the, you know, either of the two cohorts. What we're guiding to is that we have a sufficient number that we can complete the analysis, and we'll provide that top line data in the third quarter. I think we'll have to be satisfied with that for now. I think that's the guidance we're seeking. Understood. Thank you. Thanks for the question. Our next question comes from Yigal Nochomovitz with Citi. Your line is open. Hi, team, this is Ashiq Mubarack on for Yigal. Thanks for taking my questions. Just on the NPM1, do you have clarity on the number of NPM1 patients you need to enroll to hit your timeline on? Have you spoken with the FDA on specifically NPM1? Yeah. Thanks, Asher. Yeah, thanks for the question. We had previously disclosed 64 patients, NPM1 patients, as we had laid out the three cohorts. 64 patients is the number that we'll look to enroll. We have, of course, spoken with the agency about not only NPM1, but KMT2A. We've had, you know, a fair amount of interaction with them over the several months since we started this program. We've aligned on our not only our design, but all the statistics that go into, you know, each of the cohorts. Yeah, nothing really new there. It's still the same number of patients that we had guided to produce. Okay. Are you able to provide any clarity on where you are in terms of hitting the 64 patient number? Yeah, thanks for the follow-up. Only that we've guided to the second half of the year. Sometime in the second half of the year, we'll be able to. Okay. -quickly announce that we've enrolled the 64, and you'll be able to figure out from there exactly when or whereabouts we are with presenting top line data. Okay, got it. Maybe one more on axatilimab. For the frontline combo trial with ruxolitinib, which you're starting later this quarter, how should we be thinking about maybe the combinability of axatilimab with ruxolitinib, maybe in terms of potential for overlapping toxicities, maybe such as pneumonia or liver enzymes, for example? Is there any color you can share on combinability? Thanks. Yeah, thanks. Thanks for the question, Ashiq. Maybe I'll have Briggs address the overlapping toxicities. Just to point out, I think the trial, this is Incyte's combination trial that they'll be kicking off. I think the guidance is later this year. We didn't specify first quarter in particular, but I think it's a trial we're all looking forward to. Maybe, Briggs, if you could address the overlapping toxicity. Yeah. Look, I think that was part of the keen interest of Incyte in wanting to partner with us on axatilimab, because at least if you look at the monotherapy toxicities of each agent, they look like they would combine quite well. That, of course, is the purpose of the initial phase of the combinations, is to characterize that. Going into that trial, we would be quite optimistic that we could get full doses of both agents. Okay. Got it. Thanks for taking my questions. Thank you. Our next question comes from Brad Canino with Stifel. Your line is open. Good afternoon. Thanks for taking the questions. This is Brad. Doesn't sound like I can get more out of you on AUGMENT-101, so maybe I'll ask about the status of the phase I clin pharm work you're doing around the multiple doses of revuevumenib for the CYP inhibitor strength. Should we expect a data disclosure from that this year? Brad, thanks for the question. As you, I think, pointed out in your question, these are supportive, these are supportive trials or this particular trial is a supportive piece of our filing, central filing for revumenib, and that work is ongoing. I don't think we've guided to when we would necessarily disclose data from that trial. I think we related to certain pieces of this. There will be data that comes out in the ultimate, in the ultimate filing where we disclose data, but I don't think there's any particular timeline related to when we might disclose for that particular study. Thanks for the question. Okay. Then maybe one on the safety data for the Beat AML, 'cause it's exciting to get some combo data this year. I guess, to set expectations for that, can you discuss the revumenib dose being used there? Is it all the 163 on a strong CYP, or is there any dose escalation of revumenib taking part in that combo? For the Ven/Aza component, what is the schedule for Ven? Does it require continuous dosing, or can physicians use the shortened schedule that's often used in clinical practice now? Thank you. Yeah. Brad, very good question, and maybe I'll let Briggs address both of those. Yeah. It, you know, the starting is the. The standard Ven/Aza is a labeled regimen. Obviously there are protocol specified dose interruptions if needed, but the request was to start with the labeled regimen. Then there is a dose escalation component to the revumenib, but everybody is on a strong inhibitor. Great. Thank you. Thank you, Brad. Our next question comes from Peter Lawson with Barclays. Your line is open. Great. Thanks for taking the questions. I guess just around NPM1, just any update around how enrollment's proceeding there, and then I've got a question on axatilimab. Thanks, Peter. Thanks for the question. MP enrollment is going well. It's KMT2A is going well as well. I think they're both... There's great enthusiasm. Certainly since ASH, I would say that investigators have, you know, really engaged with us and have really related to the data that they saw at the meeting. NPM1 enrollment is going well. There's, you know, and I think that relates to our ability to complete enrollment in the second half of this year. Then you had a follow-up. Just around axatilimab, just with Sanofi's Rezurock, just with that launch, kind of how do you look at that and gauge your own potential launches? How should we think about peak revenues and whether you think this is ultimately a single agent or a combination agent regimen? Thanks for the questions, Peter. Yeah, look, I think you heard in my remarks, Rezurock has done well. Its first year of sales, upwards of, you know, $250 million in sales. Impressive. This is our drug has a different mechanism of action, we think impressive results thus far in its clinical trials. You know, I think the opportunity here in chronic graft-versus-host disease is to access patients in the relapsed refractory setting. I think these patients tend to, over their course of their treatment journey, they tend to get multiple therapies. They cycle through the different therapies. Our opportunity, we think is what Rezurock and/or, you know, Jakafi experienced in the third line, the ability to pick up meaningful share. Ultimately, this, and that's just monotherapy, but ultimately the opportunity here extends itself well beyond just monotherapy into potential combinations. Rezurock, you know, has its own opportunity for combinations potentially. The mechanism of action of our drug is non-overlapping with Jakafi. That's the, as Briggs pointed out, that's the, you know, reason why I think we're so excited about being able to combine it in a frontline setting and potentially reduce the use of steroids, which could really expand the use of this drug beyond what, you know, Rezurock has even shown in relapsed refractory in the first year. You know, if you think about that, a little harder, first year sales in $2-$250, that's showing to be a potentially very large opportunity. Again, that's just in relapsed refractory third line plus, disease. The opportunity to go in combination, and get the patients earlier in their treatment journey, I think really portends well for our drug. I think, you know, was there something else to your question, Peter? No. That was great. Thank you so much. Yeah. Thank you. Our next question comes from Kalpit Patel with B. Riley Securities. Your line is open. Yeah. Hey, good afternoon. Thanks for taking the questions. You mentioned that the enrollment for the NPM1 cohort is going well. I'm just curious about the timing differences versus the KMT2A cohort. Is that just a function of when these trials started enrolling? Just trying to understand the gap there. Thanks, Kalpit. Good question. Look, as I said, we are pleased with the enrollment for and the physician enthusiasm for both NPM1 and KMT2A. I do think that, you know, BTD has its sort of advantage to our filing strategy for KMT2A, the ability to combine cohorts, may have something to do with our ability to kind of move slightly more quickly with KMT2A. I think that's part of it. The other part of it is that KMT2A, you know, there's probably a little less competition for patients with our competitors. You know, NPM1 may be drawing more patients into the various studies. I do think that there are some competing factors here, some contributing factors here. Ultimately, I think, we're doing quite well with NPM1, and we feel that, you know, getting to market as quickly as we can with KMT-two-A will advantage us greatly as we bring data behind for NPM1 and hopefully get that approved as well. Okay. Maybe one question on the combo studies. Has the dosing commenced for the Beat AML study? I think you stated that we're just expecting safety this year, so I was just wondering if dosing started yet. Yes. Thank you for the question, Kalpit. Yeah, the combination studies have initiated. There's the, again, the AUGMENT-102 chemo combination that has been enrolling patients, as well as the Beat AML trial that is also enrolling patients. They both start. Okay. All right. Fantastic. Thanks for taking the question. Thank you. Our next question comes from Bert Hazlett with BTIG. Your line is open. Thanks. Thanks for taking the question. Just one or two for me. Could you just remind what the consideration of revumenib post-transplant. Is there a regulatory or an indication strategy there? Are you thinking about that as a compendium listing or publication strategy? Just could you just frame how you're thinking about that from a regulatory perspective? Sure. Briggs, do you wanna take that question from Bert, please? Yeah. Bert, in the ongoing pivotal trials, we allow patients to go back on to revumenib. If they have a response, go to transplant, they can go back on revumenib. That work in the pivotal trial, we don't anticipate a label indication for that. Best case scenario is we might be able to describe in the label that how the trial was conducted. I think that information will be mostly gotten out into the community through publications. It does set us up for potentially a formal maintenance trial down the road. The way we're handling it in the pivotal trial, there won't be a claim regarding maintenance. Okay. That's helpful. Thank you. Then just shifting gears from a corporate perspective, back to axatilimab. I believe you have a co-promote option there, and you've hired a head of commercial relatively recently. How are you thinking about that decision, and is there a particular timing in which that needs to be executed on your part? Great. Thanks for the question. Good question. You're correct. Our agreement with Incyte does include a co-promotion option on axatilimab. That election is made in proximity to filing. It is something that we'll have to, you know, kind of, let people understand a little bit better in the coming months as we get closer and closer to that time point. Obviously, we'll have a filing, as we said, before the end of the year. We're thinking actively about it. I would just say that we have two programs that, as we've described today, and as you know, that are really on top of one another in terms of timing, both for filing and then approval. The commercial opportunities, while not the same, are may have some synergy in terms of the doctors that are being called on and how we promote these products. The thought potentially is that there could be some very nice synergy between what we do with revumenib and axatilimab, and so that we're thinking actively about whether the co-promotion option makes sense for us. Okay, thanks. I know it may be early, but any thoughts on Salesforce sizing, infrastructure, things like that? Sure. It's a lot longer conversation. I would say that this is a focused, commercial effort, meaning that, these are not, very large patient populations. More importantly, they're covered by, you know, a reasonably focused number of physicians. So the field force to cover it is, you know, somewhere in the order of 40 to 50 reps. We'll refine those estimates and start to give some more color to what the organization looks like that we're building. We are actively engaged in bringing in leadership, to the company in order to be ready in time for launch for, both of these products. Terrific. Look forward to more. Thanks. Thank you, Bert. Our next question comes from Joel Beatty with Baird. Your line is open. Great. Thanks for taking my questions. First one is on the pooled KMT2A cohort. Do you anticipate that the efficacy will be presented just for the pooled cohort on the label, or could there also be a breakdown of AML and ALL on the label? Yeah. Joel, great question. I think that was sort of alluded to or part of another question that was asked earlier. The strategy for pooling is that, you know, we'll be presenting a, you know, total number of patients, and they'll be analyzed. I think, of course, the agency will look at all the subsets, and will have a breakdown of that, and I think that that'll be part of our package. Essentially, the analysis, the primary analysis that will be done is on the pooled patient. Okay, thanks. A question on R&D expenses. It looks like they'll ramp up over the course of 2023. Any priorities that you anticipate will be a part of that increased spending? Yeah, Joel, this is Keith. I'll take that one. You know, a lot of the increase in 2023 will go towards the initiatives that Michael laid out in his comments. You know, we have a pretty expansive development program for revumenib to realize the full potential. The current pivotal programs are focused in relapse refractory, obviously. Going forward, you know, you heard Michael expand upon all of the work needed to again, recognize the full potential, looking, you know, frontline combos, maintenance therapy, et cetera. You know, additionally, in anticipation of a filing by year-end, and to be ready for a launch in 2024, there'll be an increased increase in CMC/tech opt expenses to get our registration batches manufactured. Remember, we do have not only a solid tablet formulation that we'll be bringing to market, but also a liquid formulation as well. That's the majority of the increase. Great. Thank you. Thank you, Joel. It appears we have no further questions at this time. I'll turn the program back to Michael Metzger for any additional or closing remarks. Great. Thank you, operator. Thank you all. We look forward to seeing many of you at the Cowen and Barclays Healthcare Conferences in the next few weeks in March. With that, I wish you all good night. Thank you. This does conclude today's program. Thank you for your participation, and you may disconnect at any time.
