Good morning and welcome to the Axsome Therapeutics Q4 and Full Year 2024 Conference Call. Currently, all participants are in listen-only mode. Later, there will be a question-and-answer session, and instructions will be given at that time. As a reminder, today's conference call is being recorded. I'll now turn the call over to Darren Opland, Director of Corporate Communications at Axsome Therapeutics. Please go ahead. Thank you. Good morning, and thank you all for joining us on today's conference call. This morning, we issued our earnings press release, providing a business update and details of the company's financial results for the Q4 and full year of 2024. The release crossed the wire a short time ago and is available on the investor section of our website, along with the earnings presentation accompanying today's call. Those joining via webcast may advance through the slides at any time during the discussion. During today's call, we will be making certain forward-looking statements regarding, among other things, the efficacy, safety, and intended utilization of our investigational agents, our clinical and non-clinical plans, our plans to present or report additional data, the anticipated conduct and the source of future clinical trials, regulatory plans, future research and development plans, commercial plans, and possible intended use of cash and investments. These forward-looking statements are based on current information, assumptions, and expectations of future events that are subject to change and involve risks and uncertainties that may cause actual results to differ materially from those contained in the forward-looking statements. These and other risks are described in our periodic filings made with the Securities and Exchange Commission, including our quarterly and annual reports. You are cautioned not to rely on these forward-looking statements, which are made only as of today's date, and the company disclaims any obligations to update such statements. Joining me on the call today are Dr. Herriot Tabuteau, Chief Executive Officer; Nick Pizzie, Chief Financial Officer; Hunter Murdock, General Counsel; and Mark Jacobson, Chief Operating Officer. Herriot will begin with opening remarks, including an overview of the important progress we've made in 2024 and a look ahead into the rest of 2025. Following Herriot, Nick will review our financial results, and then Ari will provide a commercial update. We will then open the line for questions, which will be taken in the order they are received, and with that, I'll turn the call over to Herriot. Thank you, Darren, and good morning, everyone. In the last two and a half years as a fully integrated R&D and commercial organization, Axsome has both expanded and deepened its leadership within CNS. Our portfolio today comprises three differentiated in-market products, three innovative product candidates in regulatory submission stage, and numerous ongoing Phase 3 trials. This broad portfolio positions us to potentially commercialize seven products or indications through 2027, allowing us to deliver significant innovation to patients and value to shareholders. 2024 was another year of strong execution for Axsome. For the year, we delivered total net product revenue of $386 million, reflecting high double-digit year-over-year growth for Auvelity and Sunosi. We expect continued growth in 2025, supported by our second completed sales force expansion for Auvelity, further improvements in market access dynamics, and increasing awareness of our differentiated products. Based on the recent performance, Auvelity is on track to reach blockbuster potential. Most recently, we received U.S. approval of Symbravo on January 30th as a novel oral acute treatment for migraine. Based on its clinical profile, Symbravo represents an important development for patients living with migraine. With Symbravo, we now have three commercial stage products and are actively preparing for its commercial launch. Before turning the call over to Nick and Ari, who will expand on the strong financial and commercial performance in the year, I'd like to provide an update on our rapidly advancing late-stage pipeline and speak about key priorities for 2025. 2024 was highly productive from a clinical development perspective as we read out five pivotal trials and initiated three Phase 3 trials across our portfolio. Our R&D execution in 2024 positions us to potentially deliver several important milestones in 2025. Starting with the AXS-05 for the treatment of Alzheimer's disease agitation, last year we completed a Phase 3 clinical program in this indication, which consisted of four controlled Phase 3 efficacy trials and a long-term safety trial. With a positive result from this comprehensive program in hand, we plan to submit an NDA for AXS-05 for the treatment of Alzheimer's disease agitation to the FDA in the second half of 2025. Moving on to AXS-12 for the treatment of narcolepsy with cataplexy. Last year, we also completed the clinical program for this product candidate, which included three controlled efficacy trials and a long-term safety trial. Based on the positive results from these studies, we plan to submit an NDA for AXS-12 for the treatment of cataplexy in patients with narcolepsy to the FDA in the second half of 2025. As it relates to our NDA for AXS-14 and fibromyalgia, we are in the publication stage of the submission and expect to submit the NDA to the FDA this quarter. Apart from the activity related to these NDA submissions, we anticipate top-line readouts from several Phase 3 trials in the near term. These include the EMERGE Phase 3 trial evaluating Symbravo in patients with prior inadequate response to oral CGRP inhibitors, the FOCUS Phase 3 trial of solriamfetol in ADHD, and the PARADIGM Phase 3 trial of solriamfetol in major depressive disorder. Top-line results for all three of these studies are on track for the Q1 of 2025. Enrollment for the ENGAGE study of solriamfetol in binge eating disorder and the SUSTAIN study of solriamfetol in shift work disorder continue to progress, with top-line results for both studies anticipated in 2026. All in all, across our development portfolio, we expect NDA submissions for three product candidates and top-line readouts from three Phase 3 trials in the coming months. I am proud of the excellent progress we've made as an organization and look forward to another transformative year as we build upon our commercial success and advance our CNS pipeline. With that, I'll hand the call over to Nick. Thank you, Herriot, and good morning. Today, we'll discuss our Q4 and full year 2024 results and provide some financial guidance. Total product revenues were $118.8 million and $385.7 million for the Q4 and full year, representing year-over-year growth of 66% and 88%, respectively. This consisted of net product sales of $117.3 million and $381.7 million for the Q4 and full year of 2024, and royalty and milestone revenue of $1.4 million and $4 million, respectively. Total product revenues for the comparable periods in 2023 were $71.5 million and $204.9 million. Auvelity net product sales were $92.6 million and $291.4 million for the Q4 and full year of 2024, representing 89% and 124% year-over-year growth. Auvelity net product sales for the comparable periods in 2023 were $49 million and $130.1 million. Sunosi net product revenues were $26.2 million and $94.3 million for the Q4 and full year of 2024, representing 16% and 26% year-over-year growth, consisting of $24.7 million and $90.3 million in net product sales and $1.4 million and $4 million in royalty and milestone revenue associated with Sunosi sales in outlicensed territories. Q4 includes a one-time $500,000 regulatory-based milestone earned by Axsome. Sunosi net sales for the comparable periods in 2023 were $21.7 million and $72.4 million. Total Sunosi revenue for the full year of 2023 was $140.5 million, which includes license revenue of $65.7 million from outlicensing Sunosi in certain ex-U.S. territories. Total cost of revenue were $10.5 million and $33.3 million for the Q4 and full year of 2024. Total cost of revenue for the comparable periods in 2023 were $7.4 million and $26.1 million. Q4 cost of revenue includes a one-time $2.5 million expense for the achievement of a sales-based milestone related to worldwide Sunosi sales. Total cost of revenue for the full year of 2023 included a one-time cost of $5 million associated with the revenue received on out-licensing Sunosi in certain ex-U.S. territories. Research and development expense were $55 million and $187.1 million for the Q4 and full year of 2024, respectively, compared to $30.8 million and $97.9 million for the comparable periods in 2023. The increase was primarily related to the company's ongoing Phase 3 trials of solriamfetol in ADHD, MDD, binge eating disorder, and shift work disorder, the advancement of Phase 3 trials of AXS-05 and AXS-12, manufacturing costs for AXS-07 and AXS-14, as well as higher personnel costs, including non-cash stock-based compensation associated with organizational growth. Selling, general, and administrative expenses were $113.3 million and $411.4 million for the Q4 and full year of 2024, respectively, compared to $86.8 million and $323.1 million for the comparable periods in 2023. The increase was primarily related to commercialization activities for Auvelity and Sunosi, including sales force and marketing expenses, and higher personnel costs, including non-cash stock-based compensation associated with organizational growth. Net loss for the Q4 of 2024 was $74.9 million, or $1.54 per share, compared to a net loss of $98.7 million, or $2.08 per share for the comparable period in 2023. The net loss in the Q4 of 2024 includes $35.9 million in non-cash charges, comprised primarily of $22 million in stock-based compensation expense and $11 million in acquisition-related contingent consideration expense. Net loss was $287.2 million, or $5.99 per share for the full year of 2024, compared to a net loss of $239.2 million, or $5.27 per share for the full year of 2023. The net loss for the full year includes total non-cash charges of approximately $125 million, which includes $85.2 million in stock-based compensation expense, $28.1 million in acquisition-related contingent consideration expense, and $6.4 million in intangible amortization, compared to $62.6 million, $48.9 million, and $6.4 million, respectively, for the full year of 2023. Auvelity and Sunosi GTN discount in Q4 of 2024 were both approximately 50%. Due to negative seasonality effects in Q1, we anticipate that GTN discounts for Auvelity and Sunosi to be in the mid-50s. We ended 2024 with $315.4 million in cash and cash equivalents compared to $386.2 million at December 31st, 2023. We believe that our current cash balance is sufficient to fund anticipated operations into cash flow positivity based on the current operating plan. I would now like to turn the call over to Ari, who will provide a commercial update. Thank you, Nick. Axsome delivered another strong quarter of demand growth for Auvelity and Sunosi in the Q4 of 2024, capping off a successful year of increased awareness and utilization of our medicines. For both products, patients and providers continue to report a significant positive impact on both symptoms and quality-of-life measures. Our performance throughout 2024 is a testament to the impact of Axsome's dynamic, digital-centric commercialization platform, which has enabled consistent growth across our portfolio and is poised to support the launch of Symbravo as an acute migraine treatment for adults in the coming months. Auvelity once again led the market in total demand growth for the quarter, with approximately 158,000 prescriptions representing 10% quarter-over-quarter growth and 87% growth compared to the Q4 of 2023. By comparison, the antidepressant market grew less than 1% sequentially and grew 2% compared to the Q4 of 2023. Nearly 26,000 new patients were prescribed Auvelity in the quarter, bringing the total number of new patients started on Auvelity since launch to approximately 165,000. Our sales team successfully activated 4,100 new providers in Q4, with primary care providers representing the greatest source of prescriber growth. Auvelity experienced meaningful positive impact of improved coverage dynamics in Q4, with increases in total covered claims. Auvelity access is 78% of all lives across channels and 63% of lives in commercial. Importantly, our market access team is actively engaged with payers across the payer landscape to expand and improve access in 2025. Moving on to Sunosi, total prescriptions were approximately 49,000, representing 4% sequential growth and 16% growth versus Q4 2023. By comparison, the wake-promoting agent market grew 1% sequentially and grew 5% compared to the Q4 of 2023. Approximately 4,100 new patients started Sunosi in the quarter, bringing the total number of new patients started on Sunosi to approximately 81,000 since launch. Approximately 400 new writers were activated in Q4, resulting in a total cumulative prescriber base of nearly 14,000 healthcare providers since launch. Payer coverage for Sunosi in Q4 was stable, with 83% of lives covered across channels. Finally, we are excited to launch our third product, Symbravo, in the coming months. Symbravo represents an innovative and highly differentiated treatment for migraine. Migraine remains the leading cause of disability among neurological conditions for the more than 39 million migraine sufferers in the U.S., and more than 80% of migraine patients discontinue their acute migraine treatment in the first year of treatment. Feedback from headache specialists and neurologists clearly positions Symbravo as a compelling treatment option for patients who have been frustrated by the limited impact of existing treatments. We look forward to sharing additional details of our commercial launch plan soon. In closing, 2024 was a very successful year for Axsome, our second full year as a commercial enterprise, and we are very pleased with the growth of both Auvelity and Sunosi. Our robust commercial capabilities and innovative digital-centric commercialization platform position Axsome to deliver on the promise of our pipeline and improve the lives of those impacted by CNS conditions. I will now turn the call back to Darren for Q&A. Thanks, Ari. Operator, may we please open the line for questions? Thank you. At this time, we'll be conducting a question-and-answer session. If you'd like to ask a question, please press star one from your telephone keypad, and a confirmation tone will indicate your lines in the question queue. You may press star two to remove yourself from the queue. For participants using speaker equipment, it may be necessary to pick up their handset before pressing the Star keys. To allow as many as possible to ask questions, we ask that you please limit yourself to one question. Thank you. And the first question today comes from the line of Ram Selvaraju with H.C. Wainwright. Please proceed with your question. Thanks so much for taking my question. With respect to DTC promotional activities, whether those are for Auvelity or Symbravo, can you comment on the cadence with which you expect those to be initiated and what strategies you might employ in order to optimize the efficiency of DTC buys? Sure. Yeah. Thanks for the question, Ram. As we've discussed previously, we intend to launch a broad-based media outreach plan for Auvelity this year, in the coming months, and the way we think about it is ensuring that our spend is sufficient to drive awareness among patients and remain competitive in the depression market, where most of the branded agents are advertising pretty broadly. In terms of sort of the media plan, we haven't commented on that specifically, but there are some calendar year seasonality considerations that we'll take into account and just make sure that when we are investing in media, that it's during a time of the year that makes sense where patient flow in HCP offices is at a high level. Regarding Symbravo, we haven't commented on our commercial go-to-market plans yet, but expect to share some more details in the coming months. Thank you. Our next question is from the line of Charles Duncan with Cantor Fitzgerald. Please proceed with your question. Yes. Good morning, Herriot and team. Thanks for taking the question and congratulations on a nice year. For commercialization, as well as the products for pipeline productivity, I had a question with regard to the sales force expansion for Auvelity. I'm wondering if you could provide any color on the relative size or change, and then whether or not that is going to create synergies with the prescriber base, the future prescriber base for Symbravo, and how that might happen. Sure. Yeah. Thanks, Charles. So, as we mentioned previously, we added approximately 40 additional representatives to the Auvelity sales team. That's about a 10%-15% increase in sort of the overall sales force size. And yes, I think your question about synergy with Symbravo, particularly when you think about migraine treaters in the primary care setting, we do believe that there's some overlap that we'll be able to take advantage of. And so more to come on that, but one of the key aspects of our portfolio is the high overlapping comorbidities with depression across all of the indications that we're studying. And so there does create some synergy or efficiencies with certain providers. That makes sense. If I may just ask a quick pipeline question, that's on AXS-05. You've mentioned the second half of the year for submitting the NDA, and I believe that that's gated by a stability test. So, analysis ongoing. So I'm wondering if you have any greater color. Would you anticipate that in third quarter or Q4? I know you're really busy with a lot of NDA submissions now. Hey, Charles. It's Mark. Good morning. Thanks for the question. So just to clarify one thing, the rate-limiting step is building the submission. It's not a stability time point. That's the gating factor. And second half, you can expect updates from us, but it is a top priority for the organization. And so we'll be looking to do that as early in the second half as possible, but we'll provide more granularity as we get closer. Thanks, Mark. Thanks for taking the question. Thanks. Thanks, Charles. The next question is from the line of Joon Lee with Truist Securities. Please proceed with your question. This is Asim Rana on for Joon. Congrats on the quarter, and thanks for taking the questions. Will the Alzheimer's disease agitation filing be an NDA or an sNDA? And then, have you had the pre-NDA meeting for AXS-12 for narcolepsy, and what are some of the legal scenarios? Thank you. I'll take the first one, this is Mark, again. So we haven't communicated the filing approach just yet, but you can expect to hear that from us in the not-too-distant future. And I'm sorry, could you repeat the second question on 12? Yeah, sure. Just have you had the pre-NDA meeting for AXS-12 for narcolepsy and just some legal scenarios that you might see? Thank you. We haven't yet confirmed the timing around the meeting, but I think as soon as we have outputs, we'll look to share that with you all, and scenario planning, I think we're so close to that, or commenting on different scenarios, the hypotheticals, that we're so close, I think we can, in the not-too-distant future, just share specifics with you on the strategy. Thank you. Our next question is from the line of Joseph Thome with TD Cowen. Please proceed with your question. Hi there. Good morning. Congrats on the progress, and thank you for taking my question. Maybe just given the upcoming data in ADHD, what is sort of a clinically meaningful change on the AISRS that you're looking for? And is Supernus Qelbree a good comp here in terms of, I guess, overall data package and sort of the progress of their launch? Anything different with some story on the topic that you can point out that might be particularly differentiated would be helpful. Thank you. Sure. Thanks, Joe. We're very close to announcing results for the Phase 3 trial in ADHD. So a lot will depend upon what the results show. So we're just as excited as the rest of you to open the envelopes and learn about the clinical profile in a multi-center study. As it relates to what we're looking for, with regards to the study, what we're looking for would be a positive trial. That is a study which meets its primary endpoint. And we're not looking for any specific difference between the treatment arms. This is the first study that we are conducting with solriamfetol in ADHD. And as it relates to your question, comparing it to Qelbree, that remains to be seen. So we'll have to look at the data, and we'll know soon. Thank you. The next question is from the line of David Hoang with Deutsche Bank. Please proceed with your question. Hi there. Thanks for taking my question. Congrats on a successful quarter and fiscal year. I was wondering if you could just talk a little bit about the expectations for seasonal cadence of scripts and revenues for Auvelity in 2025, particularly Q1, where we typically see some headwinds, how the sales force expansion efforts might pull through, and if you would feel comfortable providing forward-looking guidance for the product at some point. Thanks. Yeah. Thanks, David, for the question. In terms of seasonality from a demand standpoint, we do expect Q1 to be a growth quarter, but somewhat slower growth than what we experienced in the back half of the year. We are optimistic of the impact of the sales force expansion. We've already seen very good leading indicators in terms of sales activity, call activity. And if you recall from last year when we had another expansion, we started to see the impact of that team towards the end of Q1, which initially showed up as incremental growth in weekly NBRx or new patient starts. So we would expect something similar. I think historically, when you look at the depression market, Q1 and Q3, the summer months tend to be somewhat slower than others for the overall market. But Auvelity is a growth brand. We expect to drive meaningful growth throughout the course of the year, but there will be some dynamics that the overall market will experience. Yeah. David, it's Nick. As it relates to providing sales guidance, with the fluid nature of many of the market dynamics and unpredictability of external factors, which include payer coverage, Field Force expansion, and other promotional efforts that could have material impacts, we don't plan to provide sales guidance currently. What we have shared, and you can reference the deck that's been filed, is that for Auvelity, peak sales for Auvelity in MDD alone are in the $1 billion-$3 billion range. For Sunosi, in its current indications, $300 million-$500 million. And then also for Symbravo, $500 million-$1 billion in peak revenue. So we remain confident in these ranges, and as we continue to commercialize, we can provide further guidance. Thank you. The next question is from the line of David Amsellem with Piper Sandler. Please proceed with your question. Hey, thanks. So my one question is this: with the exclusivity runway for Auvelity shortening up and with good visibility to significant cash generation, how are you thinking about M&A/BizDev in terms of your ability and willingness to bring in an asset or assets where you can leverage the commercial infrastructure that you have in place? Or alternatively, would you even bring in a development stage asset? Just let us know how you're thinking about that philosophically. Thanks. Sure. Yeah. Hey, David, it's Nick again. We are always looking for opportunities. We're obviously very satisfied with where we are with our late-stage pipeline and our commercial assets, but something that potentially can complement something earlier stage in our pipeline, we are open to. We have dedicated resources internally now to evaluate opportunities, and that is something that's on our radar. Thank you. The next question is from the line of Marc Goodman with Leerink Partners. Please proceed with your question. Nick, can you help us with how to think about expenses this year? And secondly, just on AXS-12, second half for filing, can you just give us what the gating factors are to wait for that filing? Thank you. Yeah, sure. Marc, it's Nick. So I'll speak a little bit about the OpEx and the quarter as well as 2025. R&D spend was slightly higher during the quarter as we were closing out the three ADHD trials and continuing to progress on all the other programs. We anticipate the R&D spend peaked this quarter, Q4, and do expect R&D spend to moderate in 2025 given the conclusion of the ADHD trials and other trials concluding in Q1. As it relates to OpEx, we do expect to see an increase versus Q4. However, we expect sales to increase at a faster rate, putting us on track to achieve cash flow positivity. We're starting to see leverage in the P&L and sales growing faster than OpEx, which we're super excited about. And good morning, Marc. With respect to AXS-12 and the NDA, so we did share we plan to have a pre-NDA meeting with the FDA, so that's a component, but the rest is just building the modules and building the submission itself. The clinical program's done, so it's really a lot of back office work now in order to get to that filing date, and then the other consideration that I'll just mention is this is the same division as Alzheimer's disease agitation, so you might expect that we'll be running some air traffic control in terms of how we're working to choreograph workflows and things like that. Thanks. Our next question is from the line of Graig Suvannavejh with Mizuho Securities. Please proceed with your question. Thanks so much. Thanks for taking my questions. Congratulations on all the progress in the quarter and the past year. Just two quick questions for me. One, just on the PARADIGM study for Solriamfetol and MDD, expectations there, and could you just remind us of the positioning if you were to see a positive readout in MDD, the positioning of that product, especially vis-à-vis Auvelity? And then just on Symbravo, can you provide a sense of what you think the launch trajectory and uptake might look like? I think rizatriptan is the second most prescribed drug generically, at least for migraine. And so would the expectation be a relatively smooth uptake, or do you think it could be more gradual given maybe some education around the product? Thanks so much. Great. Thanks for the questions. I'll take the first one. As it relates to the PARADIGM study and expectations, this PARADIGM will be the first study that we're conducting with Solriamfetol in MDD. So we're very close to having a readout, so we'll learn a lot from that. As it relates to potential positioning, as you know, Solriamfetol is approved to treat excessive daytime sleepiness, and there is a lot of overlap in terms of comorbidities between excessive daytime sleepiness and depression. So a natural fit or a natural way to look at this product, if it were to have an effect in MDD, would be to position it for patients who have those two comorbidities. So we've disclosed that one of the ways that we've conducted the study is to also look at patients who have EDS and MDD versus those who have MDD without EDS. That will provide us some very nice information about how the product works and how the mechanisms of action, which we think are very relevant, would translate clinically to an appropriate patient population. Hey, Graig, this is Ari. So regarding the Symbravo uptake, obviously, we're very optimistic about the impact Symbravo will have on the acute migraine market. When you look at analogs, we believe the more recent launches are probably more accurate in terms of uptake. I'm referring to the oral CGRPs. The product does have a unique clinical profile relative to both the triptans as well as the oral CGRPs. So we do think that there's a very compelling position for the product. With that said, one of the things that you should think about when modeling Symbravo is we are being very targeted, very focused on headache specialists and neurology practices that make up roughly 70% of the overall branded market. W e'll be launching with something smaller than the two large oral CGRP competitors out there. So it remains to be seen exactly what the uptake will look like, but I do think that those are probably the closest analogs to assess. Thank you. The next question is from the line of Vikram Purohit with Morgan Stanley. Please proceed with your question. Hi, good morning. Thanks for taking our questions. We have two on the pipeline. So first, going back to the ADHD filing plan for the second half of the year, I know you're not guiding the specifics on the filing strategy, but could you help us understand, I guess, some of the regulatory and commercial factors kind of feeding into how you're thinking about NDA versus sNDA, what the practical implications could be of one path versus the other? And then secondly, I think you recently mentioned that the AXS-14 NDA submission is on track for 1Q25 for fibromyalgia. So I was just wondering if you could talk a bit about which patient segments AXS-14 could be a good fit for within fibromyalgia, assuming it's approved, and what you see as the commercial potential there. Thank you. I'll start with the question about the different considerations for the filing strategy for AD agitation. It's cross-functional, right? There are considerations with respect to brand name. There are considerations with respect to intellectual property, market access strategy, and some regulatory considerations. So it really touches on every element of development and launch, and I think we'll be able to comment specifically in the not-too-distant future which path we're taking. Yes. As it relates to fibromyalgia, one of the aspects of the disease is that it has multiple symptoms, and the current treatment options do not adequately address all of those symptoms, so what's nice about the profile of AXS-14 to date is that not only does it reduce pain, but it also improves function, and it reduces multiple symptoms of fibromyalgia. One key symptom of fibromyalgia that the data has shown could be really impactful to patients, and that AXS-14 does have an effect on is fatigue, which is very difficult to treat, and patients consider it to be one of the top three symptoms of fibromyalgia that result in their disability, so we're very excited about the potential for AXS-14 in fibromyalgia, especially given the large patient population. Got it. Thank you. The next question is from the line of Jason Gerberry with Bank of America. Please proceed with your question. Hi, good morning. This is Dina on for Jason. Thanks for taking our questions, and congrats on all the progress this year. We just had a couple on Solriamfetol for ADHD. Just one follow-up regarding the Phase 3 clinical profile. Would your $1-$1.5 billion in peak sales estimates change at all if we did see stimulant-like efficacy in the PARADIGM trial, which is maybe around that 20%-25% placebo-adjusted benefit on AISRS endpoint? And then can you just remind us what your plans are for the adolescent population and maybe how we should be thinking about the size of the adult versus adolescent opportunity in terms of market share? Thanks. Sure. The ADHD patient population is so large and still remains underserved despite the various treatments that are available. I think there'll be a very sizable market opportunity for solriamfetol should the studies be positive. So we're very close to having a data readout, so we look forward to learning more about the efficacy profile of the drug potentially in ADHD. As it relates to the pediatric population, as a reminder, we must generate data in the pediatric population in order to be able to submit an NDA to the FDA for consideration for ADHD. And so that is something that we plan to do. So we've talked about initiating that study and launching that study. In order to do that, we do need to get feedback from the FDA on the pediatric study plan, and that is in progress. Thank you. The next question is from the line of Leonid Timashev with RBC Capital Markets. Please proceed with your question. Hi, guys. Congrats on the progress. I just wanted to ask on maybe some additional color on the patent settlement around Auvelity with Teva. I guess first, how did you end up deciding on sort of the 2038, 2039 boundaries? And then maybe bigger picture, I guess, how does it change your peak assumptions for Auvelity versus sort of what you put forth in the slide deck around both MDD and Alzheimer's agitation? Thanks. So thanks for the question. This is Hunter. I'll take the first part first, and then Nick, do you want to take the second part? Sure. Great. So the dates were just a negotiated resolution. It didn't tie to a specific event or a specific occurrence. It was just what was sort of negotiated at an arm's length transaction, Teva. Nick, do you want to? Yeah. With the recent developments on the LOE, we do plan to update and refine our guidance as the launch progresses, and having the LOE day will help facilitate that process. So stay tuned. The next question is from the line of Serena Chen with Wells Fargo. Please proceed with your question. Hi. Thanks for taking my question. Wanted to ask about Symbravo. Just given the high rebating environment around oral CGRPs, how should we think about factors that could impact net price and anything differentiated Axsome is doing to compete there? Thank you. Yeah. Thanks for the question. We'll obviously have a lot more to share as we prepare for the commercial launch, but as you mentioned, this is a high rebate category. We also saw the oral CGRPs launch with significant free goods in the market, and so we've been able to study the dynamics of those launches to formulate our strategy and plan for engagement with payers. We feel very, very confident in the clinical profile of Symbravo. The fact that we have data across pain intensities, very compelling data providing relief or pain freedom and freedom from both bothersome symptoms at two hours extended to 24 hours. There's a very strong clinical rationale for Symbravo, and in our early discussions with payers, we do see the potential to engage in access discussions for the brand. So we'll be able to share more as we get closer to the launch, but we are very mindful of building access while also maintaining long-term profitability for the brand, and that's one of our key areas of focus. Thank you. The next question is from the line of Ami Fadia with Needham & Company. Please proceed with your question. Thanks for taking my question. With several assets in late stage, can you maybe just talk about your philosophy or how should we think about operating margin evolution over the next two, three years, and specifically just for this year as well with the launch of Symbravo, maybe if you can give us a more granular color on how to think about operating expenses, that would be helpful. Thank you. Sure. I'll handle, i'll start with the second question first. Just as we successfully launched Auvelity, we're going to take a strategic approach in launching Symbravo and plan to continue to assess the investment over time. For Symbravo, we're confident in our ability to execute with an efficient SG&A spend in 2025 by leveraging our DCC approach, and we'll invest as needed to build consistent growth trajectory over the long term. The approval, subsequent launch of Symbravo has always been factored into our cash runway, and as a reminder, our current cash does take us into cash flow positivity. As we think about operating margin over the next couple of years, we have the same strategy that we've always had with Auvelity as well as Sunosi, very focused on ROI and being mindful of how we invest in each dollar within the SG&A as well as in the R&D function to ensure that we get the ROI top line. The next question is from the line of Yatin Suneja with Guggenheim Partners. Please proceed with your question. Hey, guys. Thank you for taking my question. Congrats on all the progress. Just a question on AXS-12 or reboxetine. Curious to hear how you are thinking about the narcolepsy market in general. I mean, we have gotten mixed feedback from the KOLs, specifically given that it is an SNRI, but you definitely have very interesting data that you have generated across multiple Phase 3 programs. So how are you thinking about that program, the opportunity there, and any impact from or actions that could have on this sort of indication? Yeah. Thanks for the question. We're very optimistic about the impact of AXS-12, and we recognize that there will be some education around the mechanism and the product and what makes it unique relative to some of the generic SNRIs that have been used historically. But in terms of market opportunity, this is a very compelling market. Approximately 185,000 patients suffering from narcolepsy, 70% of those suffer from cataplexy, and dissatisfaction, inadequate response with existing treatments is very, very high. So we see a real opportunity for AXS-12 in this marketplace, and we'll share some more details on our thinking on the approach that we'll take as we get a little bit closer to the filing. The next question comes from the line of Myles Minter with William Blair. Please proceed with your question. Hi. Thanks for taking the question. Maybe one for Nick. Is there any material impact of the Medicare Part D restructure that took effect January 1st on Auvelity revenues? And I'm also wondering what the mix is of patients that are getting access to Auvelity through the Medicare system versus commercial payment and if that ratio is going to change over the next few years. Sure. Sure, Myles. As it relates to Part D, we don't expect a significant impact. There might be just a little bit of a change in how GTN evolves throughout the year, but overall, we don't anticipate an impact at this point. Yeah. And related to the mix, so currently, Auvelity is roughly 15% Medicare. Our TRx volume is 15%. We don't expect any significant changes to that. Obviously, with the potential for AXS-05 and Alzheimer's disease agitation, there will be a much heavier focus on Medicare for that product, that indication. And so we'll have to share some more as we finalize our plans around sNDAs/NDA. Cool. Thanks. Thank you. Our final question is from the line of Joel Beatty with Baird. Please proceed with your question. Good morning. This is Chris Chen on for Joel. Just a question on AXS-05, not in ADA, but in smoking cessation. Just wondering if you could add a little more color on maybe a potential timeline in 2025, and then just more specifically, are you incorporating any differences between users of traditional cigarettes versus e-cigarettes? Thank you. Thanks for the question. Right now, where we are in terms of the plans for the Phase 3 trial, we're very confident that this study will start this year. We're looking forward to sharing with you more of the details of the study design. The initial trial will look at patients who smoke cigarettes. In terms of patients who use other forms of nicotine, that will come at a later date, but for our registration trial, it will be in the smokers. Thank you. At this time, there are no additional questions, and I'll hand the floor back to management for closing remarks. Thank you for taking the time to join today's call. 2024 was a busy year for the company with the continued success across all aspects of our portfolio. As we sit here today on February 18th, our business reflects an expanding commercial enterprise and rapidly advancing late-stage neuroscience pipeline poised to deliver potentially five innovative products in 10 serious neuropsychiatric conditions that collectively impact the lives of more than 150 million people in the U.S. alone. We look forward to updating you on our continued progress throughout the year. Thank you, and have a great rest of your day. This will conclude today's conference. You may disconnect your lines at this time. Thank you for your participation.
