Axsome Therapeutics, Inc.

Good morning and welcome to the Axiom Therapeutics conference call. Currently all participants are in a listen only mode. Later we will conduct a question and answer session and instructions will follow at that time. As a reminder, today's conference call is being recorded. I would now like to turn the conference over to our host, Mark Jacobson, Chief Operating Officer at Axiom Therapeutics. Please go ahead, sir.

Thank you, Operator. Good morning and thank you all for joining us on today's conference call.

These and other risks are described in our periodic filings made with the Securities and Exchange Commission, including our quarterly and annual reports. Your caution not to place undue reliance on these forward-looking statements, which are made only as of today's date, and the company disclaims any obligation to update such statements. Joining me on the call today are Dr. Ariel Tibuto, Chief Executive Officer, Nick Pizzi, Chief Financial Officer, Lori Engelbert, Senior Vice and Dr. Cedric O'Gorman, Senior Vice President of Clinical Development and Medical Affairs. Ariel will first provide an overview of the company and then review recent development and upcoming milestones. Following Ariel, Lori will comment on our commercialization approach and then Nick will review our financial results. We will then open the line for questions. I shall now turn over the call to Ariel.

Thank you, Mark. Good morning, everyone, and thank you all for joining Axome Therapeutics' third quarter 2020 financial results and business update conference call. Over the past several months, we continued to advance our AXS05 and AXS07 product candidates towards NDE submissions in major depressive disorder and migraine, and we intensified our commercial launch readiness activities. Committed capital from our recently announced term loan facility combined with cash on hand approached $400 million, strengthening our balance sheet through these anticipated commercial launches. In the quarter, we also advanced the rest of our late-stage pipeline, including two positive FTA breakthrough therapy designation meetings for AXS05 in Alzheimer's disease agitation and AXS12 in narcolepsy. and we scheduled an FDA meeting for AXS14, our product candidate for the treatment of fibromyalgia. Our intellectual property portfolio continues to grow with recently issued and allowed patents for AXS05 in depression now extending to 2040. We anticipate an active next few months as we complete our NDA submissions for AXS05 and AXS07 release top-line efficacy data from open-label trials with these product candidates, initiate Phase III trials for AXS05 and AXS12 in Alzheimer's disease agitation and narcolepsy, and meet with the FDA on AXS14 for fibromyalgia. I will provide a brief pipeline update before handing it over to Laurie, who will discuss our commercialization strategy for AXS05 in depression. then Nick will discuss our financial results. Starting with AXS05, our novel oral and MDA receptor antagonist. Pre-submission activities for the MDA for AXS05 for the treatment of MDD are nearing completion. We expect to submit the MDA in January instead of by year end reflecting a COVID-19 related logistical delay from one vendor. We have completed the Phase 3 open-label long-term Comet Safety Trial of XSO5 in depression. The three Phase 2 open-label efficacy sub-studies of the Comet trial have also been completed, and we are on track to report top-line results from these efficacy studies by year-end. Our placebo-controlled MERIT trial in TRD, or treatment-resistant depression, is on track to report results in the first half of next year. Moving on to our program in Alzheimer's disease agitation with AXS05, which received FDA breakthrough therapy designation in June. Results of the subsequent breakthrough therapy meeting for the syndication confirmed the pivotal status of our positive completed ADVANCE-1 trial. Consequently, only one additional Phase III trial is needed to support the filing of an NDA for AXS05 in this indication, and we remain on track to initiate that study before year end. Switching now to our migraine program with AXS07. The major NDA-related items are on track for completion by year end. We now plan to submit the NDA in the first quarter of 2021 versus previous guidance of the fourth quarter of 2020 in order to allow for inclusion of supplemental manufacturing information. We believe that this approach will enhance the robustness of our submission. We have completed the movement phase three open label long-term safety trial of XSO7 in migraine. We now expect to announce efficacy results from this trial in the fourth quarter of 2020. Moving next to our NARCCL-FC program with AXS-12, which received FDA breakthrough therapy designation in August. We recently announced the expedited development status and plan for AXS-12 following a breakthrough therapy meeting. One phase three efficacy trial, which along with the previously completed phase two concert trial will be used to support the filing of an NDA for approval of AXS-12 for the treatment of cataplexy, and narcolepsy. We remain on track to initiate this phase three trial in the first quarter of 2021. Ahead of the potential launches of AXS05 and AXS07 starting next year, our commercial readiness activities have been accelerating. These activities include the build out of our proprietary digital centric commercialization or DCC platform, Our partnership with Viva Systems announced yesterday will provide digital technology that will be incorporated into the DCC platform. We are excited both by the clinical profile of our product candidates and our planned commercialization approach. I will now turn it over to Lori, who will provide some observations as it relates to the growing need in depression and some insights into our planned commercialization approach.

Thank you, Ariel, and good morning, everyone. We are excited to talk to you this morning for the first time about our commercialization plans. As you may have noticed, yesterday we announced a partnership with Viva to help build our proprietary digital-centric commercialization platform. I will speak more about why we believe this commercialization approach makes sense for us later, but first I'd like to remind everyone why we believe AXS05 has the potential to have such a significant impact on the MDD market. we are increasingly excited about the opportunity to meaningfully change the way physicians view what's achievable with the pharmacological treatment of depression and to have a lasting impact on patients. It should come as no surprise that the pandemic is having a profound effect on people. One of the most striking effects is the sharp rise in depression. Results of an epidemiological study recently published in JAMA demonstrated that the number of US adults with depression symptoms This increase is even more notable given the prevalence of depression was already high pre-pandemic. The increase is heavily skewed towards individuals who are already in the moderate to severe depression category. On top of a sharp increase in prevalence, the MDD market still has extremely high unmet needs. Through primary market research with physicians and patients, four areas continually identified as high unmet needs are one, physicians want new, different patient-friendly approaches to treatment. While there are many approved agents, all current oral antidepressants work primarily through the monoaminergic system. Two, physicians and patients want faster onset of action. Most commonly used therapies today take six to eight weeks to reach therapeutic effect. Three, physicians want better opportunities for remission. We know through published research that only about a quarter of patients on a standard antidepressant achieve remission within a 10 to 14-week timeframe. And four, patients and physicians want to stop trading off efficacy for safety and tolerability. Current standard antidepressants typically are associated with weight gain, increased sexual dysfunction, and cognitive impairment. If successfully developed, AXS05 has the potential to address these unmet needs. and bring meaningful advancements to physicians and patients for the treatment of MDD. Since the approval of tricyclic antidepressants in 1959, there has been no new oral mechanism of action for MDD. As an NMDA receptor antagonist, AXS05, if approved, would be the first new oral mechanism of action for the treatment of MDD in over 60 years. In clinical trials to date, treatment with AXS05 has been associated with rapid release of depression symptoms, including achievement of remission as compared to both placebo and active comparators. Importantly, benefit was seen in both patient and physician reported outcomes. AXS05 was well tolerated and was not associated with weight gain, increased sexual dysfunction, or cognitive impairment in our trials. As I mentioned earlier, yesterday, to help build our proprietary digital-centric commercialization or DCC platform. The Axiom DCC platform incorporates specialized digital tools, proprietary data and analytics, integrated systems, and an intelligent operating model. The goal of using evolving technology and digital execution is to optimize physician and patient engagement and thereby increase the effectiveness and efficiency of our promotional efforts as compared to traditional approaches. Using a digital-centric commercialization approach will, one, allow us to make extensive use of remote detailing, have real-time data fed to seamlessly integrated platforms that use sophisticated technology to allow our reps to make informed, dynamic decisions. And two, allow us to leverage the evolving digital ways in which patients and clinicians access information. The decision to take this digital-centric commercialization approach was data-driven. On this slide, we highlight some key HCP trends that give us confidence we are taking the right approach. One, remote detailing, which was about 10% pre-COVID, has increased significantly and is leveling out around 50% of all engagements. Two, psychiatrists, our primary physician target for AXS05, have been the heaviest adopters of remote detailing. offices were remote. And three, remote detailing appears to result in significantly longer engagements with physicians, with a remote detail averaging around 25 minutes versus less than five minutes for a traditional in-office call. This is an indicator that physicians are becoming more comfortable with the approach and that remote calls can be highly effective. Key trends for consumers are very clearly trending towards digital. As shown on the chart on this slide, time spent with digital media has been rapidly increasing in the US in recent years, surpassing traditional media for the first time in 2018. And within just two years, digital media time is already 25% higher than traditional media. This is a trend that we expect to continue to grow. We believe that the macro trends around the current mental health crisis, virtual detailing, adoption by physician, and the increased reliance on digital by consumers are unlikely to change after the pandemic. Given what we know about the marketplace, HCP and consumer trends, combined with the potential for AXS05, our initial launch engagement strategy will include an extensive use of remote detailing, augmented by conventional detailing as needed, and primarily focused on psychiatrist and mental health-focused PCPs. We believe that this approach will not only increase quality and effectiveness, but also significantly reduce the cost per physician interaction, providing greater flexibility in rep number and reach. For patients, we intend to focus our engagement on using a digital omnichannel approach. We are very excited about our first launch and believe our digital-centric commercialization, or DCC platform, approach is not only scalable, but also relevant for all flat-alone launches. This approach should provide HCPs and patients meaningful engagements that are optimized and differentiated. I look forward to sharing with you more about our plans in the future. I would like to now turn over the call to Nick, who will provide a financial update.

Thank you, Lori, and good morning, everyone. Today, I will discuss our third quarter 2020 results and provide some financial guidance. We ended the third quarter with approximately $202 million in cash compared to roughly $191 million at the end of the second quarter, a net increase of approximately $11 million due to the net proceeds from our new term loan facility with Hercules Capital. R&D expenses were $14.8 million for the quarter ended September 30, 2020 versus $15.8 million for the comparable period in 2019. The decrease of $1 million was driven by the completion of the majority of our clinical trials which were ongoing in the comparable prior period. G&A expenses were $6.3 million for the quarter ended September 30, 2020 and $3.1 million for the comparable period in 2019. The change was primarily due to an increase in non-cash-related stock compensation expense, along with the continued build-out of the commercial function. In the quarter, we secured a $225 million term loan facility with Hercules Capital. This committed, non-dilutive capital further strengthens the company's balance sheet and gives us additional financial flexibility through the anticipated potential commercial launches starting next year. We believe our current cash position of over $200 million, along with the committed capital from our $225 million term loan facility, is sufficient to fund our anticipated operations based on our current operating plan into at least 2024. That concludes our third quarter 2020 financial review. I'll now turn the call back to Mark to lead the Q&A discussion.

Thank you, Nick. Operator, may we please have our first question?

One moment while we compile the Q&A roster. Again, that's star one for any audio questions. We have our first question from Charles Duncan with Kantor Fitzgerald.

Hi. Good morning, Ariel and team. Thanks for taking our question. Congrats on a good quarter of progress. Looking forward to more in the near term. I have a couple of questions for you. I'll try to be brief. The first is relative to the long-term safety studies for both 05 and 07 comet and movement. I'm wondering if you can provide some color on the completion rates or persistence because it seems to me that I know those are safety studies, but in both cases, patients staying on drug is going to say something about the perception of efficacy or lack of tolerability issues for the patient over time. So I'm wondering if you can give us some color on that, and then I have follow-up.

Good morning, Charles, and thank you for the question. That is certainly something that we've looked at as a reminder. Both of these studies dosed patients over a one-year period, so that's a long time. And then one of the things that you have to do when you run studies like that is you've got to make some baseline assumptions as to what the rates would be of discontinuations. And what we can tell you is that we've been pleased with the persistence rates. and that the rate of discontinuation throughout the study have been lower than what we expected. We do intend to announce results of these studies or of the sub-studies, in the case of Comet, by year end, and at that point, we'll have more information for you.

Okay, that's helpful. So you feel like patients are remaining on the study perhaps even greater amount than you had anticipated?

So we'll have greater details for you when we report out the results of the study, but certainly in terms of the assumptions that we made for what you would expect to be the drop-off rate over a one-year period, we were pleased that it was longer. I'm sorry, we were pleased that what we actually observed was lower than what we projected.

Okay, that's helpful. And then I wanted to move on to AXS05 and Alzheimer's agitation. I listened to Cedric's presentation yesterday at CTAD, and I noted that you plan to start another, well, a phase three, the only one needed to move forward by the end of the year. And so, When you look at that presentation at CTED, it seemed like the responder rate was notable, and so I'm wondering if you could provide any color on what you thought the key takeaway was with AXS05 and Cedric's presentation yesterday at CTED.

Sure. So we were excited to present the results of the advanced trial at a scientific forum. So, we presented it before, but certainly CTAD is one of the premier forms for Alzheimer's disease-related illnesses. And the key takeaways are that this is a rare finding, having efficacy in this patient population in this indication. So, you know, we were very pleased with the results of the ADVANCE-1 trial, and not only was there a very significant reduction in symptoms, but the reduction was clinically meaningful. One of the takeaways when you look at the data, we thought was the fact that the average reduction from baseline symptoms is about 50%. So, very strong set of results. And of course, not only do you want to control symptoms, but you want to make sure that the safety profile is there and that the drug is well-tolerated, especially in this vulnerable population, and so we're pleased with that outcome, too. I'll let Cedric maybe make some comments, if he has any, with regards to the reaction from the forum and thereafter, after our presentation, from the scientific community.

Yeah. Hi, Charles. Thanks, Ariel. And, you know, the main takeaway from the CTAT was there was a great level of interest. At one point, the attendees numbered close to 600. So that was really great. We were encouraged by that. And then, as Ariel said, the translation of the improvement in symptoms on the primary outcome measures, the CMAI, into clinically meaningful response rates And I think the fact that there's no drug approved for AV agitation Had a lot of people excited with the data. And then, of course, in the safety perspective, not associated with sedation or cognitive impairment, so important for this patient population. High rates of completion in the study and low rates of falls, similar to placebo, which was also good. So I think, taken in totality, people are looking forward to the next trial and the continued development with exosulphide miscommunication.

In that presentation, you mentioned that the trial was being designed. I imagine you're probably pretty far down the process of doing that. Can you provide some color on what that next phase three looks like in terms of size or timing and endpoints?

Charles, we're very close to providing all that information. As we mentioned in our prepared remarks, we are on track to launch that that confirmatory phase three trial this year. What we have disclosed, of course, are general parameters around the design. This will be a randomized withdrawal design. And so we like that design feature. This will be placebo controlled. And that relates to your size question. Since this will be a two-on trial, we would expect it to be smaller than the last just by the fact that it's two arms versus three arms. But we'll provide you additional details soon as we get ready to start the study by year end.

Okay. Thanks, Ariel. Thanks, Cedric, for the added color. Thanks for taking my question.

Thank you. We have a question from Mark Goodman with SVB Lyric.

Yeah, good morning. So, Ariel, can you just give us a little more color on two issues? One, you mentioned that 05 has been delayed into January because of one vendor. How much are we on top of that situation such that you're very confident that it's only going to be delayed into January? Or is this one of those things where It's a little open-ended. And then the second issue was for 07, you talked about the NDA in the first quarter, including extra manufacturing information. Can you give us kind of the same sense of confidence that, you know, my first question, you know, with respect to what's going on here, maybe give us a little more color and how much we're on top of it, and, you know, it's definitely going to be not, you know, any more delay than that.

So thanks, Mark, for those questions. With regards to AXS05, it is one vendor, and the logistical issue is very straightforward. Because of COVID-related backup, they are not able to deliver a report to us until the very end of December. So that's later than we had expected. So we're on top of it, and we will definitely get that by the end of December. But we wanted to make sure that we let you know that it could slip into January. So we're pretty confident that we'll be able to file it in January. So it is one isolated vendor and it is only a report. So with regards to AXS07, this is a little bit of a different situation Here, this is a situation whereby by the end of the year, we will have completed all the major activities which are needed to file our NDA, and we're on track to do that. And because of the unique manufacturing behind the MOSAIC technology, we want to make sure that we have as robust as possible of a submission package. So we continue to generate data, and the question is, how much do you include? And since we will be having some data in the early part of the year, we'd love to be able to include that in the package. But to provide some additional color on that, I'm going to turn it over to Mark Jacobson.

Good morning, Mark. So just want to be clear, this is not the result of a manufacturing or stability issue or anything like that. It's exactly as Ariel said, that we will have data available that we think would add to the submission, given it's a novel delivery technology. And so that will just allow us to make the package as robust as possible.

Thanks. Thank you. Once again, for any questions, you may press star 1 now on your telephone keypad. We have a question from Yatin Sanjaya with Guggenheim Partners.

Hey, guys. Thank you for taking my question. I have two questions. First, with regard to the merit study, can you maybe, I think you did make some comment that I missed, but can you maybe just talk about what characteristics of the drug you need to further elucidate before you start a phase three in TID? And then, you know, do you actually need a phase three or maybe this one could be sufficient? So that's one piece. And then with regard to the comet disclosure that we're going to have, again, this is going to be non-perceival control. So just trying to get a sense of what level of disclosure you'll make and how should we interpret those data given lack of placebo in the study. Thank you.

Thank you, Jan. So with regards to the MERIT trial, this is a study in PRD. It is a randomized withdrawal study. And so that will give us some new information with regards to O5 in that study design, because all of our prior studies have been parallel group studies. These data will supplement data that we will be releasing by year end. from our COMET TRD trial, which is open label, as you mentioned. But with regard to TRD, remember that the label that we'll be filing for is MDD, which is the broadest indication, and that includes all subsets of major depressive disorder, which includes patients who failed one antidepressant, or patients who fail to a more antidepressants who may be classified as treatment resistant. As well as in patients who have suicidal ideation, et cetera. So we have a broad label which captures the entire spectrum of MDD patients and the point of the MERIT trial as well as the common sub-studies is to provide data to clinicians in terms of how the product performs in these various populations. So by the time that we launch the trial, we hope to have, we will have, we hope to have these data, some of these data published, and certainly we'll be sharing them with you before year end. Now for the comment sub-studies, as you mentioned, so these are open label trials, but we do measure efficacy And we do expect to get meaningful data from those studies. And the reason for that is they reflect real world use. This is how patients are treated by clinicians. And every day when patients are treated by clinicians for their depression, the clinicians have to assess whether or not the patients are responding and how well they are doing. And typically what clinicians do is they look at improvement in symptoms, there are some objective measures too, which really do not depend on a comparative group, such as remission rates, rates of clinical response, and clinical response defined as at least a 50% reduction in symptoms. Onset of action, do patients get better faster? So while all those things are accessible by clinicians, And those are the types of measures which we'll be looking at and which we'll be providing data on when we report out these results by year end.

Just one quick question on the P&L. I mean, I see the R&D line picked up a little bit, but G&A still remains pretty reasonably low. At what point should we see an inflection on G&A, given that you would have to build infrastructure around the two launches? How should we model that? And then just if you can comment on the R&D, is it going to trend up, given that there are more studies, but there are some finishing also? Just if you can help us with the modeling a little bit, that would be great. Thank you so much.

Thanks for the question. This is Nick Teasy. So, related to your first question, when can we see a pickup in SG&A costs? Obviously, there's a lot of work that's going on right now on some of the commercial functions, and we do expect to see probably a bump in the SG&A costs starting in Q1 as we prepare for launch readiness.

Thank you. Our next question comes from Joseph Thome with Cowan & Company.

Hi there, thank you for taking my questions. The first one on Alzheimer's agitation, if you could just give us, I know there are others that are looking at more episodic treatment for acute agitation associated with Alzheimer's. If you could just give us, based on your research, could a episodic product and a chronic treatment be used in combination or would these be sort of two separate subsets of patients? And then second, on AXS07, you know, looking ahead to that launch, we touched on AXS05. Would this remote and virtual launch plan be amenable to AXS07 in migraine and with neurologists, or would you have to kind of tailor the approach when it comes time? Thank you.

Hi, Joseph. Thank you for the question. and I think an important characteristic to remember about XSO5 and AV agitation is this is a treatment which would be chronic and the goal of that treatment would be to prevent patients from actually ending up in an institution, whether that be a nursing home or a hospital ER because their symptoms are uncontrolled. So from that perspective, I guess, There is no reason a priori that various treatments, let's say treatments for very acute disease, which results in patients needing additional care, there's no reason to think that our product would not be used with other treatments. I think that that's normal. And then with regard to your question around AXS07 and AXS, the applicability of our DCC platform to commercialization of that product candidate. I'm going to turn it over to Lori.

Hi, Joseph. So first let me just set the groundwork that part of the benefit of us being able to utilize the DCC platform is that we get the benefit of building this from scratch. A lot of companies, due to the pandemic, have had to retrofit their systems as well as their sales forces. So we're actually in a very good place as we think through the launches that are coming up and are purposely scaling this, making a platform that is scalable to our upcoming launches. If you noticed on the receptivity of remote detailing or virtual detailing, neuros are also extremely high. In fact, psychiatrists and neuros typically are in the top three of the ones that are most receptive. to remove detailing.

Great. Thank you. That's very helpful.

Thank you. We have a question from Vikram Porat with Morgan Stanley.

Hi. Good morning. This is Thomas Lavery for Vikram. Your release mentions that the IP portfolio for AXS05 and oppression has recently been expanded. Can you provide us with some color in the nature of these patent claims? And if possible, can you talk about how these patent claims expire in 2040 versus the prior patents in your portfolio that expire in 2035? Thank you. Great.

Thank you for the question. What we're referring to are new patents that have been issued, which are more standard or more typical method of use patents for treating depression. And so those patents go out to, several of those patents go out to 2040. In fact, I think at least one has issued, we've gotten a notice of allowance for more and then we expect notices of allowance for even more than that. So those could number a significant number of patents for that patent family. And the way that they differ from the prior patent families is our prior patents, which go out to 2036, those were primarily pharmacokinetic patents. And what's nice about pharmacokinetic patents is one of the strong features of a pharmacokinetic patent is that it's agnostic to indication, so it covers all indications. So we wanted to make sure that we had those patents first, which we do have. And then, so this new family of patents around depression specifically are not pharmacokinetic patents. So those patents are, the new patents are based upon the positive results that we have generated in our clinical trials thus far in our efficacy trials. And by the way, this is by design. to our strategy is to continue to expand our IP portfolio. And it's nice to see that not only is it broadening and deepening, but also the runway is getting extended.

Thank you. We have a question from Ram Solverju with H.C. Wainwright.

Thanks so much for taking my questions. I think most of these are probably for Laurie. I was wondering if you could comment on the current status of the commercial organization, how established it is at this juncture, and at what stage you expect to be by the end of the year, and whether the kinetics of the establishment of the commercial organization are being impacted at all by the change in the timeline for the NDA filing. of AXS05 in particular. I wouldn't imagine that that's the case, but just wanted to verify this. And then I had a couple of additional follow-ups regarding the VIVA partnership, but maybe we can start there.

Hi, Ram. Thanks, and good morning. Thanks for the question. So the status of the commercial organization is we are actively building. As commercialization efforts ramp up, we are building to meet those efforts. We have a very strong team in place, one that I am extremely proud of, and we continue to hire at a very rapid pace. What I can tell you about the impact of timeline is, no, there are no changes due to the impact of timeline. We are planning a very unique approach to launch. There are a lot of activities and analysis being done to ensure that we are approaching the market in the right way.

Okay, great. And then with respect to the Viva partnership, maybe you can comment on two aspects that are particularly intriguing to me. Firstly, the way in which this relationship might potentially enable you to build a competitively privileged position from a commercialization standpoint relative to any potential market competitor products, entities that might be counter-detailing, and so on. And then secondly, if you can comment on what specific products in Axone's pipeline, particularly on a late-stage level, the VIVA relationship might be especially useful for, or if you expect it to be pretty much equivalently useful for all of Axone's product candidates. Thank you.

Yeah, that's a great question. And so I'll answer your second one first. As I mentioned in my previous comments, we are purposely building this in a scalable fashion. And I do think that with the approach that we are taking, where we are leveraging trends in the marketplace to be as effective as possible and building this infrastructure from scratch, allows us to be highly efficient and flexible. And so the flexible piece is, I think, very important for us. We get to monitor and optimize our approach to the market, meaning we get to monitor as adoption increases how we intend to scale. And that would be applicable to both the AXS 07 launch as well as the AXS 05. In terms of how we think this will be beneficial to us in a competitive standpoint, As I mentioned before, most companies are having to retrofit their systems. And retrofitting systems is never easy because it's clunky and it increases opportunities to be inefficient. And getting to do this from scratch from the very beginning will allow us to have very efficient, real-time, dynamic ability to optimize our engagements with both patients and physicians.

Fantastic. Thank you very much for that. Ariel, just a couple of questions on sequencing, if I may. Do you expect the meeting with the FDA with respect to the fibromyalgia indication to occur before or after the meeting with the FDA to discuss AXS05 and smoking cessation? Which one do you expect to come first? Fibromyalgia. Okay, great. And then with respect to the narcolepsy trial, can you give us a bit of color on how long you expect that trial to enroll for? What would you expect the timeframe to be between start of enrollment and completion of enrollment?

It's premature for us to comment on exact timing there. You know, what we can do is give you some parameters to maybe help you think about it. I think one determinant will be the size of the study. So once we launch the trial, and we'll provide details around sizing. As a reminder though, what we saw in the phase two trial was a very pronounced effect on cataplexy, and so the study that we'll be conducting will have that as the primary endpoint. So that study was a crossover trial with roughly 20 patients. So if it were a parallel group trial, it would have been roughly a 40 patient trial. If you look at the package inserts for at least one other drug, that has studied this level of impairment from cataphylaxis, the number of patients per arm, was in the range of around 30 or so patients per treatment arm. I'm not saying that that will be the sizing of our trial, because it will not be, but that gives you kind of a sense. And with regards to our CONSERV trial, so we were able to enroll that study in approximately six months with around 12 clinical trial sites. Again, this is not to say that this will translate directly into timing for our phase three trial, but those are certainly metrics which are available if you really search for them, and which we certainly will be using to inform our timeline projections, which we'll provide to you We'll provide you some more information around that once we launch the trial in the first quarter.

Okay. And just as a follow-up to that, do you expect to use any or all or some of the clinical sites that originally enrolled patients for CONSERV in this upcoming Phase 3? Would that be a fair assumption?

That is a fair assumption that they would naturally be overlapped.

Thank you very much. Thank you. We have time for a few more questions, and the next question comes from Matt Kaplan at Leidenberg.

Hi. Just congrats, guys, on your progress during the quarter. Just wanted to follow up a little bit on the narcolepsy development plan, and specifically, I guess, you know, with respect to beyond the clinical data from the comet study and the planned Phase III additional study, what else do you need to complete to put yourself in position to file the NDA?

Okay.

Sure. So, Matt, I think you led off with narcolepsy. I think you meant to say MDD in terms of, and correct me if I'm wrong, but I think that that's your question in terms of what remains for that MD filing. Is that right?

Well, I wanted to follow up on both of them, but yes, both narcolepsy and MDD.

Okay. Sure. So starting with MDD, where the NDA, the pre-NDA submission activities, the major ones are largely complete. So in terms of the clinical trials, for example, what could be rate limiting, specifically the Comet long-term safety trial, that we announced has been completed and we'll have the results for the Comet sub-studies by the end of the year and we'll announce those. So we're in great shape there in terms of things that need to be done from a patient perspective, from a patient data perspective. And now really it's putting it all together and making sure that we have a quality submission package. And then with regards to Narcolepsy, and what would be needed for an NDA filing there. So as you know, we did have a breakthrough therapy meeting with the FDA, and based upon the results of that meeting, we intend to conduct the one phase three trial, and the one phase three trial along with our completed concert phase two trial, those will be used for the NDA filing.

Okay, thanks for the detail. And then maybe a question for Laurie with respect to your plans utilizing the DCC approach. Can you speak to other examples of companies or products that have been launched in a similar fashion or some of the components of what you're thinking about that have been successful in the past?

Sure. So we don't believe that there are any other companies using a platform such as this to launch, and that's part of why we think this is so important and also speaks to the trends in the marketplace are what's driving our decision to do this. Largely led by what's happening with the pandemic, but it's also forcing behavior changes that we believe are not going to change in terms of adoption of remote detailing that allows for convenience as well as efficiency for both companies as well as physicians. There are several companies who have launched in a primarily remote fashion over the course of the pandemic period and have done so quite well. There have been instances where that approach worked very well. But again, what benefit we get is that we don't have to quickly pivot, meaning we don't have to take a field force that was primarily prepared to be face-to-face and switch them to remote. We don't have to reintegrate systems that could be very clunky and complicated. We get to build it from scratch, and so we think this sets us up for a very efficient position.

Thanks, Lori. Congrats again on the progress during the quarter.

Thank you. We have a question from June Lee with Trust Securities.

Thank you for taking our questions. This is Miguel on the line for June. Could you provide more specifics on what manufacturing data related to the Mosaic platform will be added for AXS07? My question is what are the key discussion points with the upcoming meeting with the FDA regarding AXS05 for smoking cessation and what is the role of the new collaboration moving forward? Thank you.

Great. So with regards to the additional manufacturing information, this is standard information when you manufacture additional batches. So we continue to manufacture additional batches of drug. And while we already have very long-term stability data on other batches, we think that because of the unique nature of the delivery technology, this can only help to make the submission robust and assure that there are no hiccups during review. With regards to the XSO5 in smoking cessation, what we're gonna be looking for from that FDA meeting is guidance on the path forward to get the product approved. That is typically what we like to do early on in development with our product candidates is to get agreement primarily with the agency on various points of clinical development that would give us confidence to be able to move quickly once we have that information. Typically, we would have gotten that information already, but with XSO5 and smoking cessation, the development there was a little bit different because we did conduct that phase two trial under collaboration with Duke University. But we're looking forward to this FDA meeting and to getting clarity on the path forward.

Thank you so much.

Thank you. We have time for one more question. It comes from Miles Mentor with William Blair.

Hey, everyone. Thanks for taking the questions. Maybe just one for Laurie. I'm just wondering, with the DCC commercial rollout, obviously the initial focus will be to really touch those neuropsychs and neurologists out there, but given the nature of the platform, have you had any considerations for primary care physicians and how they might be integrated into this program that a traditional sales force that you might implement cannot?

Hey, Miles. Thanks for the question. Absolutely. So part of our initial targeting, especially on AXS05, will be for what we're calling mental health-focused PCPs. And there's a very large subset of those who are high prescribers. And so we will absolutely use this platform to try and increase that reach. But keep in mind that this is not just a remote detailing platform. We're looking to optimize all channels and how we reach physicians. So we do believe that there are ways to be effective with the PCP market that way.

Okay, thanks for that. Maybe on the comet study, are we only going to see relapse rates from the sub-studies that you're running under that umbrella, or did every participant get a madras reading before an exit of that study? And then maybe how you're thinking about relatively interpreting that data. I know the STAR-D trial is obviously out there. We see relapse rates within a three- to four-month period. obviously 300 patients at six months and 100 patients at a year is more than enough to see something there is that the most relevant data set for this particular population or are you more willing to leverage this or compare this to real world prescribing data and what we're seeing in the clinic with ssris thanks so uh with the comment um trial uh what we'll be looking at uh is uh is

The response of patients in the study, we'll be looking at onset of action, so when do you start to see meaningful improvements from patients, and then we'll be following the patients out over time, so it'll give us a sense of, and also persistence of effects. You mentioned relapse, typically, you would look at relapse by conducting a trial which specifically looks at relapse. And those are of the randomized role study types of design. This is not that type of study. But because patients are gonna be treated, will have been treated over a one year period, We'll have plenty of information on persistence of effects.

Okay. Thanks for the questions.

Thank you. I'll now turn the call over to our speakers for any closing comments or remarks. Great.

Well, you know, we're excited about the potential of our pipeline. This is an industry-leading CNS pipeline. And we're also excited about the potential to make meaningful changes in the lives of patients with our product candidates should we develop them successfully. We expect the next few months to be very busy with our plan and the filings and our continued launch readiness activities. So we look forward to keeping you updated on our progress and we'll speak to you during the next conference call. Thank you.

Thank you. That concludes the call. Everyone may now disconnect.
