Good morning, everyone, and welcome to Curis' 4th Quarter Business Update Call. We made great progress this quarter in both NHL and AML. Let's start with our TakeAim Lymphoma study, which is evaluating emavusertib in combination with ibrutinib in PCNSL. Before we discuss the clinical data, I'd like to highlight the encouraging feedback we received from the EMA and FDA on the potential for conditional marketing authorization in Europe and accelerated approval in the U.S. As a reminder, we engaged both agencies about the potential for accelerated filings after the initial early data from PCNSL patients treated with emavusertib in combination with ibrutinib last year. We met with the agencies in the second half of 2024 and are pleased to announce that both agencies reviewed and provided feedback on our proposed plans for the potential for an accelerated approval pathway based on our ongoing TakeAim Lymphoma study. As a reminder, the study is a single-arm, open-label study being conducted in the U.S., EU, and Israel using ORR as the primary endpoint. Both agencies agreed that patients already enrolled in the trial can be used in the submission as long as they meet the same inclusion/exclusion criteria. They also provided helpful guidance on additional information, such as contribution of effect, to be included as part of the submission and initial thoughts on the design of our confirmatory study. In short, the discussions were very productive. The development timeline for emavusertib just got accelerated. Our current phase I-II study is now registrational for both the U.S. and Europe. Obviously, this is the outcome we were hoping for. With over 30 clinical sites now open for enrollment, our goal is to complete enrollment in the next 12-18 months. With that, let's turn to the clinical data. As a reminder, we're testing the emavusertib-ibrutinib combination in two distinct PCNSL populations: BTKI naive patients and BTKI experienced patients. The thesis for the emavusertib-ibrutinib combination, supported by both preclinical data and clinical data, is that blocking both of the pathways driving disease in NHL—blocking the TLR pathway with emavusertib and blocking the BCR pathway with ibrutinib—maximizes downregulation of NF-kappaB and can enable patients to achieve an objective response, even if they've been previously treated with a BTK inhibitor and progressed on that treatment. In our press release this morning, we summarized the clinical update for 27 relapsed refractory PCNSL patients in our TakeAim Lymphoma study, including 20 BTKI experienced patients and 7 BTKI naive patients. Among the 20 BTKI experienced patients, change in tumor burden data were available for 13 of them at the cutoff date. Nine of these 13 patients demonstrated a reduction in tumor burden, including six objective responses, four CRs, and two PRs, with three of the four CRs lasting more than six months. Among the seven BTKI naive patients, change in tumor burden data were available for six of them at the cutoff date. Five of these six patients demonstrated a reduction in tumor burden, including five objective responses, one CR, and four PRs. In summary, we're very encouraged by both the clinical data and the clarity from EMA and FDA on our proposed registrational plans. Over the next 12- 18 months, we'll be focused on enrolling 30-40 additional patients to support a filing for accelerated approval. Finally, to cap off our progress in NHL this quarter, we're pleased to announce that emavusertib has been granted orphan drug designation for primary CNS lymphoma in both the U.S. and in Europe. With that, let's turn to AML. At the ASH conference in December, Dr. Eric Winer from Dana-Farber presented data for 21 patients with a FLT3 mutation who had received fewer than three lines of prior therapy and were treated with emavusertib as monotherapy at the RP2D of 300 mg b.i.d. These data show a 38% composite CR rate in the salvage line setting, with 10 objective responses in 19 response-available patients, six full CRs, two CRs with partial or incomplete hematological recovery, and two morphologic leukemia-free state responses. We were especially encouraged to see that these responses were achieved rapidly, with seven of 10 responses reported at the first assessment. To put these data in context, we know that FLT3 patients in the relapsed refractory setting typically receive gilteritinib, a FLT3 inhibitor which was approved with a composite CR rate of 21%. It is important to remember that this 21% rate was in an ideal population of patients predominantly naive to FLT3 inhibition. The emavusertib study, on the other hand, was in salvage line patients. Over 80% of the patients on emavusertib had already been treated with a FLT3 inhibitor and failed. We believe the reason emavusertib data were so compelling is its novel mechanism of action. It blocks both IRAK4 and FLT3. For several years, it has been suggested in the literature that blocking IRAK4 can enable patients to overcome adaptive resistance to FLT3 inhibition. These clinical data clearly support that thesis. Finally, I'd like to provide an update on our progress with the triplet study in frontline AML. As a reminder, in 2024, we initiated a phase I study of emavusertib as an add-on agent to venetoclax and azacitidine in frontline AML. This study is assessing safety and tolerability, where emavusertib is added to a patient's VenAza regimen in 7, 14, and 21-day dosing regimens after they have achieved a CR on VenAza and while they remain positive for minimal residual disease. We have successfully completed the 7-day cohort, and enrollment of the 14-day cohort is currently ongoing. In short, we had a very productive 2024 and have entered 2025 with positive momentum. We look forward to providing you with additional updates as the year progresses. With that, I'll turn the call over to Diantha for the financial update. Diantha. Thank you, Jim. Curis reported a net loss of $9.6 million, or $1.25 per share, for the fourth quarter of 2024, compared to a net loss of $117 million, or $2.03 per share, for the same period in 2023. Curis reported a net loss of $43.4 million, or $6.88 per share, for the 12 months ended December 31, 2024, compared to a net loss of $47.4 million, or $8.96 per share, for the same period in 2023. Research and development expenses were $9 million for the fourth quarter of 2024, compared to $10 million for the same period in 2023. The decrease was primarily attributable to lower clinical research, consulting, and employee-related costs, partially offset by higher manufacturing costs. R&D expenses were $38.6 million for the 12 months ended December 31, 2024, compared to $39.5 million for the same period in 2023. General and administrative expenses were $3.4 million for the fourth quarter of 2024, compared to $4.9 million for the same period in 2023. The decrease was primarily attributable to lower legal, facility, consulting, and employee-related costs. G&A expenses were $16.8 million for the 12 months ended December 31, 2024, compared to $18.6 million for the same period in 2023. In October, we completed a registered direct offering and concurrent private placement with net proceeds of approximately $10.8 million. On March 28, 2025, we priced a registered direct offering and concurrent private placement of common stock, pre-funded warrants, and warrants with gross proceeds of approximately $10 million. The impact of these two offerings has extended our cash runway into the fourth quarter of 2025. With that, I'd like to open the call for questions. Operator? Thank you. Ladies and gentlemen, we will now begin the question and answer session. To ask a question, you may press the star followed by the number one on your telephone keypad. If you're using a speakerphone, please pick up your handset before pressing any keys. To withdraw your question, you may press the star followed by the number two. With that, our first question comes from the line of Kripa Devarakonda, with Truist Securities. Please go ahead. Hi, good morning. This is Nicole for Kripa. Can you just talk a little bit more about cash runway and how we should be thinking about expenses going forward and any additional cost modulations we should be considering as we update our models? Yeah. Actually, Diantha, why don't you walk through that? Absolutely. We have previously guided that our burn is about $10 million a quarter, and that continues to be the case. Again, the proceeds from these two offerings that we did in the fourth quarter of last year and the first quarter of this year extend our cash runway from mid-2024 to the fourth quarter of 2025. Okay. Great. One quick follow-up. Can you just talk a little bit about any potential inbound interests from partners? In this environment, are there any additional hurdles for partnerships other than fitting into the landscape? Sure. As you can imagine, given the utility that we've seen so far in NHL and AML, we're on radar screens. I would say just as a matter of course, we expect that we will be continuing to have discussions on how to best move our program forward. At some point, I suspect that's going to involve partnering with one of the major players in either the NHL or AML space. Stay tuned. Thanks so much. Your next question comes from the line of Sean McCutcheon with Raymond James. Please go ahead. Hey, guys. Thanks for the questions. Can you remind us how many primary central nervous system lymphoma patients have been given the 100 mg b.i.d. dose of emavusertib to date, either as monotherapy or in combination with ibrutinib, and perhaps walk us through the necessary steps to meet the FDA's requirement on the individual component contributions? Obviously, based on your commentary, it's a review issue for the number of patients you'll need. Would you anticipate the number at a go-forward dose being roughly in line with what the EMA expects? Thanks. Yeah. Actually, Jonathan, you're probably the best to address that one. Sure. To date, we've dosed 13 patients at 100 milligrams. Those patients have been dosed in part B of the study. Remind me of the second part of the question. The second part was just the steps you'll need in order to meet the FDA's requirement on the individual component contributions and then roughly the number of patients you'd expect to need within the US at a go-forward dose. Yeah. We would expect that the U.S. and Europe will be using similar data. When we think about the dose selection, we'll be able to make that after about nine patients that have been dosed on 100 and 200. Yeah. Thanks. Your next question comes from the line of Li Watsek with Cantor Fitzgerald. Please go ahead. Hi. Li Watsek, you might be on mute. Yes. Thank you. Good morning. Thank you so much for the update and taking our question. We were wondering if you could give us a little more color on what the EMA might expect in terms of compelling and consistent data in terms of the response rate that you have mentioned. Thank you. Sure. Why don't I start on that, and then I'll ask Jonathan to opine as well. I think what both agencies clearly, I think, were so supportive of our efforts to bring a treatment to primary CNS lymphoma, based on the data that we've seen to date and the data that we've seen to date are very compelling. Obviously, we would be hoping that as we complete enrollment in the study, that the data remain consistent and that the compelling results that we've seen to date hold as we finish out enrollment in that study. Jonathan, would you like to add your thoughts? Yeah. The only thing I would add is both agencies clearly acknowledged there are no approved treatments in this space. I think that's why we had favorable discussions with them. As Jim mentioned, where the response rate is today, as long as we are probably north of 25%, we should have positive momentum with both agencies. Great. Thank you very much. If you would like to ask a question, simply press the star followed by the number one on your telephone keypad. Your next question comes from the line of Ed White with HC Wainwright. Please go ahead. Hi. Thanks for taking my question. You just had mentioned the agencies looking for north of 25% ORR. Is this a bit of a change? I think in the past, you've mentioned that they're looking for a CR rate above 20%. No. Let me add to that, and then I'll ask Jonathan to opine as well. Yeah. I think what we're really looking to do is to ensure that we've got data that are consistent with the past and, of course, give us a 95% confidence interval that we can beat a null hypothesis of 10%. So 20% clearly does that. We're much higher than that now. I think if we end up somewhere in a 25% range, we've got a lot of cushion over the 95% confidence interval. I think really that's all we were saying, that we're going at the salvage line setting in these patients simply because there really aren't good options for these patients. If we continue to see the kind of efficacy that we've seen to date, we should be in a good position. Jonathan, do you want to add your thoughts on that? Yeah. Nothing to add to that, Jim. That's accurate. Okay. Jim. Thank you. How should we be thinking about TakeAim Leukemia? It seems like you're focusing on PCNSL patients. Should we expect to see more enrollment in the leukemia study, and also should we expect to see more data later this year? Yeah. I want to be more cautious about what kind of data in leukemia that we're going to see later this year. I think the two places where everybody's excited is, of course, on the triplet study and then in potentially a monotherapy study in FLT3. On the triplet study, as we mentioned in the release and in my comments, we've completed enrollment in the 7-day cohort, looks safe and well tolerated. Our goal would be, of course, to do the same for the 14 and 21-day studies. Once we've established safety, and that's the critical item in that study, make sure we can show that adding emavusertib to current standard of care is safe and tolerable. Then we would move, of course, to start dosing with all three drugs starting day one. At that point, we're looking for efficacy. We're looking to see whether adding emavusertib does the same thing in the clinic that it did in the lab. That is, it added efficacy to the venetoclax-azacitidine doublet. That would be one thing that we would look to move toward in leukemia. On the other side, of course, there's a lot of interest among the KOLs for a monotherapy extension into the FLT3 population. It looks as though at this point, the data we have suggests emavusertib is a best-in-class FLT3 drug as a monotherapy, which makes sense, right? It's the only drug that blocks IRAK4 and FLT3. It should be the best in class. We would need to run another study, a pivotal study to prove that and to gain approval. There is a lot of enthusiasm for that path as well. I would look forward, hopefully, as the year progresses and we make progress in getting those studies initiated, we'll have a better sense of timelines and can be able to set for you what data we would expect when. Does that make sense? Yes. Thanks, Jim. Great. Thanks, Ed. Ladies and gentlemen, this concludes our question and answer session. I would like to turn the conference back to the company's President and CEO, Jim Dentzer, for any closing remarks. Thank you, Operator. Thank you, everyone, for joining us on today's call. Thank you to our teammates at Curis for their hard work and for our partners, especially at Aurigene and the NCI and at academic sites helping us develop this important drug. We appreciate your time today, and we look forward to providing updates in the near future. Operator? Thank you. Ladies and gentlemen, this concludes today's conference call. Thank you all for joining. You may now disconnect.
