Good morning and welcome to the Axsome Therapeutics Conference Call. Currently, all participants are in a listen-only mode. Later, there will be a question-and-answer session and instructions will follow. at that time. As a reminder, this conference call is being recorded. I would now like to turn the conference over to your host. Mr. Mark Jacobson, Chief Operating Officer at Axsome Therapeutics. Please go ahead.

Thank you, Operator. Good morning and thank you all for joining us on today's conference call. Our earnings press release, providing a corporate update and details on the Company's financial results for the Second Quarter of 2021 crossed the wire a short time ago and is available on our website at Axsome.com.

Joining me on the call today are Dr. Herriot Tabuteau, Chief Executive Officer; Nick PZ, Chief Financial Officer; Dr. Kevin Laliberte, Executive Vice President, Product Strategy; Lori Englebert, Senior Vice President of Commercial and Business Development; and Dr. Amanda Jones, Senior Vice President for Clinical Development. Herriot will first provide an overview of the Company and then review recent developments and upcoming milestones. Following Herriot, Lori will provide a commercial update, and then Nick will review our financial results. We will then open the line for questions. Questions will be taken in the order they are received. And with that, I will turn the call over to Herriot.

Thank you, Mark. Good morning everyone, and thank you all for joining Axsome Therapeutics’ Second Quarter 2021 financial results and business update conference call. Since our last update, we continued to make significant strides toward becoming a premier CNS biopharmaceutical company focused on delivering potentially life-changing medicines to people living with serious CNS conditions. I will provide an update on our development pipeline before turning it to Lori, who will provide a commercial update. Starting with our first lead product candidate, AXS-05, which is undergoing an NDA review for the treatment of major depressive disorder with a PDUFA date of August 22, 2021. On July 30, we received a letter from the FDA stating that as part of their ongoing review of our NDA, they have identified deficiencies that preclude discussion of labeling at this time. The letter did not state what the deficiencies are. Immediately upon receipt of the letter, and continuing through today, we have been in communication with the FDA to attempt to learn the nature of these deficiencies So that we can address them. In response, the FDA has informed the Company that their review is ongoing and that they have no specific questions for the Company at this time. Although the letter stated that the notification does not reflect a final decision on the information under review, this development may lead to a delay in the potential approval of AXS-05. We will keep you informed as we learn more. This morning in a separate release, we announced positive topline results for the Phase 2 MERIT trial of AXS-05 in treatment-resistant depression. AXS-05 met the primary endpoint by substantially and statistically significantly delaying the time to relapse of depressive symptoms as compared to placebo with a p-value of 0.002. The AXS-05 also met the key secondary…

Thank you, Herriot. And good morning, everyone. This is an exciting time at Axsome as we continue to prepare to launch both AXS-05 in major depressive disorder and AXS-07 for the acute treatment of migraine. Today, I will give you an update on our commercial activities as it relates to launch readiness. The U.S. is in the middle of a mental health crisis, and the need for awareness and support for those suffering is apparent. Recently, we have witnessed an increased spotlight on Mental health as celebrities and athletes are bringing awareness to the forefront for the many Americans who may be suffering. During the pandemic, prevalence of depression symptoms in U.S. adults has increased greater than fourfold versus 2019. One out of every three U.S. adults experienced depressive symptoms in 2020. Given the personal and economic burden associated with mental health conditions, there is an undeniable urgent need to bring support to those affected. If approved, AXS-05 would be an important new treatment option for the many Americans living with depression. We are prepared and ready to bring this meaningful innovation to patients by commercializing the product soon after a potential approval. If approval is received on our expected PDUFA date of August 22, we anticipate launch to occur within three months. Our commercial launch strategy is innovative and purposeful with the intent to bring meaningful new products to patients in an efficient and effective way. Our digital-centric commercialization, or DCC platform, is now fully implemented, and testing of the platform for execution at launch is well underway. As a reminder, we have designed our DCC platform to use streamlined systems and digital enablement tools combined with sophisticated data and analytics to allow for a more effective, efficient, and meaningful engagement with physicians and consumers. Importantly, our field leadership…

Thank you, Lori, and good morning, everyone. Today, I will discuss our Second Quarter 2021 results and provide some financial guidance. We ended the Second Quarter with approximately 141 million in cash compared to roughly $165 million in cash at the end of the First Quarter, a net decrease of approximately $23.5 million. R&D expenses were 14.5 million for the quarter ending June 30, 2021, versus 10.5 million for the comparable period in 2020. The increase was driven by cost to support the NDA filings and in personnel expense, which includes an increase in headcount along with an increase in non-cash stock compensation expense. During the Second Quarter, we received a refund from the FDA in the amount of $2.9 million which was paid in the First Quarter related to the PDUFA application fee for AXS-05 in MDD, as part of the FDA granting us a small business waiver. The current quarter included a $2.9 million charge related to the PDUFA application fee for the NDA submission for AXS-07 in the acute treatment of migraine. G&A expenses were 16.3 million for the quarter ending June 30, 2021 and 7.2 million for the comparable period in 2020. The increase was primarily due to pre-commercial activities and personnel expense, which includes an increase in headcount along with an increase in non-cash stock compensation expense. Net loss was $32.3 million or $0.86 per share for the quarter ended June 30, 2021, compared to a net loss of 18.3 million or $0.49 per share for the comparable period in 2020. As a reminder, we currently have a $225 million term loan facility, of which 175 million in funding remains available. This committed, non-dilutive capital gives us additional financial flexibility through both anticipated potential commercial launches for AXS-05 and AXS-07. We believe our current cash position of $141 million along with the remaining 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 Second Quarter 2021 financial review. I will now turn the call back to Mark to lead the Q&A discussion.

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

Certainly, sir. At this time we would like take any questions you might have for us today. [Operator instructions]. Our first question comes from Charles Duncan from Cantor Fitzgerald.

Good morning, folks. Herriot and team, thanks for taking the question, and congratulations on the MERIT trial results. However, the first question that I have is regarding AXS-05 in MDD. I know you're not going to be able to be all that definitive, but I'm wondering if you can speculate at all as to the nature of the questions that are being contemplated by the agency? Was there a full buy-in in terms of the trial designs that supported this NDA?

Good morning, Charles and thank you for the questions. So with regards to the deficiencies, we just want to reiterate that we do not know what the deficiencies are. So, the letter did not state what the deficiencies or even what discipline they pertain to. As a reminder, we did receive priority review for this application. This was a very large submission and package. To what extent that has an impact on the current situation, it's hard to say, but up until now, the review has been going on track from our perspective. We believe that we've responded adequately to all of the questions during the review period. And importantly, we have not been made aware of any deficiencies in the application up to this point. Since we've learned of the existence of these deficiencies through the letter, we have made attempts to learn what the deficiencies are; and up to this point, we still don't know. And as soon as we find out, we will let you know.

Okay. And then with regard to the manufacturing inspections that occurred during the review, were there any observations that were noted -- 483 observations?

So Charles, we haven't commented on the specifics of the inspections. And so to this day, we've not been aware of any 483s in connection with any of our inspections.

Okay. Okay. And then if I could ask one question on the MERIT trial, very intrigued with TRD results. As you know, there's a lot of work being done by psychedelic-oriented companies to generate efficacy in TRD. And I guess I'm wondering as you think about the unmet need there, which of the two endpoints are most important to you, the time to relapse or call it responder rate over 6 months, say 36% control, having response or having relapse versus 0% in the drug arm? When you talk to KOLs, what do they focus on?

Thanks for that question Charles on MERIT. So we -- the way that our study was designed, we looked at the time to relapse as the primary endpoint. This is a standard endpoint for relapse prevention trials. And -- but we also looked at just prevention of relapse as a key secondary endpoint, and that is a very important endpoint to look at. So, it's one thing for a drug to actually delay relapse of depressive symptoms, but it's a higher bar to actually prevent relapse period. And so, I think that both endpoints would be relevant to clinicians, but certainly preventing relapse if that is possible is very relevant and very -- it's something that clinicians would look for. And as the results show in the MERIT trial over at least six months of treatment, that's the minimum. Some of these patients were treated out to a year. No relapses were observed.

Okay. Very good, last question for Lori, sales contingent offers. Can you share with us the number of them that you have out, and importantly, the timelines, how long do those offers last? I assume they're contingent on approval as I think you mentioned.

Hey, Charles. And I am sorry, they are being made contingent upon approval, and we're still not revealing the size of the sales force. So, I don't want to give you that estimate just yet. We are well on our way of ensuring that we will have everyone on board by launch if we stay on the current timelines.

Okay. Thanks for taking the questions.

Thank you. Our next question comes from Marc Goodman with SVB Leerink. Your line is open.

Yes, good morning. Herriot, can you kind of help us understand how you're thinking about what the FDA is asking for you? So, maybe take us back to your meetings with FDA, your pre-NDA meeting, pre-filing, anything that's gone along in the process. What did the FDA say was needed here in the filing, and just talk about whether you feel like you've checked those boxes and maybe you can give us a little bit more detail. In the previous question, you talked a little bit about CMC. So, is it your understanding that CMC is completely done like with everything was stability, everything like, there were no issues there? I mean, we're just trying to understand here what happened. Obviously, you are too, and that we are just not going to find out until you have a meeting with them and you've requested -- you've requested a meeting, I assume or I guess you have to wait until the PDUFA date, maybe to give us a little more color there? Thanks.

Thank you Marc for the questions. So I just want to reiterate that we have not been made aware of what the deficiencies are. With regards to the process up to this point, the process has been going very smoothly. As a reminder, this is a breakthrough therapy-designated product, so we felt that we've gotten very close feedback from the agency, every step along the way including our pre-NDA meeting. And as a reminder, the filing was accepted and not only was it accepted, but it was granted priority review. So, that would be an indication that all of the boxes have been checked. With regards to CMC, all the CMC work was complete per the agreements prior to filing the application. And during the review, we've answered all questions adequately and we feel that process has been going smoothly. And in terms of requesting a meeting with the agency, as you can imagine, upon receiving the letter, we've made attempts to learn what the nature of the deficiencies are, including requesting a meeting. Now, there's still time on the PDUFA clock. Admittedly, it's -- the time is dwindling. However, as soon as we learn of what the deficiencies are of -- or of any additional details, you'll be the first to know.

Just talk about the manufacturing plants. Have they been inspected completely, like, everything as far as you're concerned is -- that belt box is checked, I mean, this is probably not a manufacturing issue.

So Mark can provide you some more details on that. But as a reminder, the product is being manufactured at a commercial blue-chip CMO that regularly gets inspected.

Hey, Marc, good morning. So just a reminder, so the drugs substances are -- the drugs substances are available under open DMF here in the U.S and from sources that we are comfortable with -- that, we have ourselves audited and inspected so that's the drug substance in terms of drug product as Aereo mentioned. That is major CDMO that makes multiple commercial products, and has numerous facilities and the facility that we use is in North America. And we have also done our inspections prior to engagement. And as Ariel mentioned, that facility is regularly inspected by FDA and we are not as mentioned earlier with any of our inspections, we're not aware of any or have not been made aware of any issues that may preclude or may lead to a development like this.

I mean, I know this might just be a basic question because you were accepted, but you have the appropriate numbers of patients for safety, you've got two positive studies at the FDA, basically said unequivocally, you had two studies. Like I'm just trying to understand where the problem is.

We are too, and as soon as we are made aware of exactly what the deficiencies are, we'll communicate them to you.

All right, thanks.

Thank you. Our next question is from Vamil Divan with Mizuho, your line is open.

Great, thanks for taking my question. Maybe one more just on this deficiencies letter we've seen a few of these now in the last few months from other companies as well. So just trying to get a sense, I think we only saw it a few weeks -- few months ago with Acadia to some thought that maybe because of COVID and the FDA being strapped and your project manager is kind of coming in and out of the review process. That may have played a role. Again, I think that was also sort of speculation, but just I'm curious if there's anything during your during your review process or maybe there were changes to personnel, or different project managers along the way, and maybe that's led now to this deficiency notice very late in the process. And then my second question just separately with the TRD data. Just curious, again. I think, as you've described it before, is ultimately you're not expecting anything around TRD in the label or an indication. And as we more verses for medical education purposes, can you just remind me if I am thinking of that correctly? Or do you think that ultimately you will be able to try and get a TRD indication as well? Thanks.

We'll take those two questions in reverse order with regards to the MERIT study and TRD, our current focus is ensuring approval and launch of AXS-05 and MDD. So we are very excited by the results of the MERIT trial, this is an additional source of data. And obviously we will be thinking about what those results mean for any kind of future plans. But currently our focus is to ensure approval in long-term AXS-05 and MDD. With regards to changes at the FDA during the review process, we do recognize as you do also, that the agency has been definitely stressed resource-wise as a result of the COVID pandemic. With -- as it relates to our particular application, there's nothing that we can point to specifically. But we do know that globally overall that the FDA is like every other organization dealing with the COVID pandemic and so the resource's strain. That comes from that.

Thank you. Our next question is from Vikram Purohit with Morgan Stanley. Your line is open.

Great. Good morning. Thanks for taking our questions. Just two for my side. So just to clarify, assuming things progress with the AXS-05, NDA and some clarity does become available in the near-term, what exactly is the plan for incorporating data from the MERIT study towards your commercial efforts and if there is one? And secondly, just going back to the deficiency letter, I think the press release mentioned some language around post-marketing commitments. Was there any additional color available on that topic from the FDA about that specific area of the NDA?

So with regards to the part of the language that we put it in the press release around post-marketing commitments. That's identical language from the letters. So we wanted to just provide it to you as we got it. So there are no specific, so nothing was identified there either with regards to specifics or -- and so we provided you exactly what's been provided to us. And then with regards to MERIT, we should mention, that said we have made the agency aware, as you can imagine, of the results. The study was unblinded over the weekend. And so, it is clearly relevant to depression as an indication in general so MDD. And we -- our focus is, of course, the indication that we file for which is MDD, and not TRD. And I'll turn it over to Lori to discuss how the study might impact commercialization.

Yeah. The data, given there was a Phase II we'll just reuse the supplemental data in our conversations. The data are very relevant to patients that physicians are having a difficult time treating and that only provides just further validation to the body of work that AXS-05 has. I do believe that the durability, that is expressed in this patient population from the study, will be highly relevant to physicians as well.

And then a quick follow-up. Understanding that this is relatively new news for you as well. But do you have any current thoughts on how the deficiency lever impacts your plans for the AXS-05 outside of MDD, whether that's with the NDA program or meeting that you were supposed to have on smoking execution with the FDA later this quarter?

We don't believe that it has any impact on the other indications.

Okay. Understood. Thank you.

Thank you. Our next question is from Ram Selvaraju from H.C. Wainwright. Your line is open.

Thanks very much for taking my questions. Again, not to beat a dead horse, I wanted to ask whether you had had any feedback from the FDA as to whether the letters that they spent was an any way related to any citizen petition they may have received regarding AXS-05?

We have not been made aware of any details related to the deficiencies. We don't know what they are or what is behind them or what's the cause is. As soon as we learn that information, we'll let you know.

Okay. And then as a follow-up to that, do you think you will be able to arrange a meeting with the FDA or obtain more clarity regarding these deficiencies before the scheduled PDUFA date or do you anticipate that this is likely to only be scheduled as the PDUFA date?

It's hard for us to speculate. As you can imagine, our goal right now with time still on the PDUFA clock is to learn the nature of the deficiencies as quickly as possible, and with the goal of addressing them. And now, whether or not we're given that information, or [Indiscernible] meetings that is not within our control, but that is something that obviously we're trying to do, and we'll let you know as soon as we get any information, or soon as there are any other developments.

Okay. And just to clarify what the potential scenarios might be. One scenario is that the drug actually gets approved by the PDUFA date and other scenario is that the PDUFA date is extended by some period of time, yet to be determined. And yet a third scenario is that there is a complete response letter and then you would have to go through the resubmission process. Is that correct?

Those are the possibilities.

Okay. And then just very quickly on the MERIT study, I just wanted to know if you had some more detailed thoughts on the perfection of relapse over the six month time frame that was reported, how significant this finding is, and how differentiated this could make AXS-05 within the TRD context?

We think it's a very important finding. And a lot of companies actually do not in relapse prevention studies, do not actually have relapse prevention as one of the endpoints because it maybe -- the drug to me may work in delaying relapse, but it's another thing to actually prevent relapse. So that that is a higher bar. So we think it is very relevant as Lori mentioned. it also speaks to the durability of activity of the drug. As a reminder, patients, prior to enrollment into MERIT had been on drugs, some of them for as long as 12 months. And then they were randomly discontinued. So, they either remain on AXS-05 or they discontinue the AXS-05 for another 6 to 9 months, at least. So that's a very long period of time to demonstrate durability of the product, so the fact that none of the patients relapsed is significant.

Thank you.

Thank you. Our next question is from Joseph Thome with Cowen and Company. Your line is now open.

Hi, there. Good morning. And thank you for taking our questions. Just a little point of clarification, based on kind of the timing of the notification from the FDA. Have you submitted any additional information to them? I think Herriot maybe you mentioned you provided sort of the [Indiscernible] results of MERIT; is that correct? And maybe how long would it take to scrub the data to give it to them in maybe a more thorough fashion, if that's necessary? And then the second point, is AXS-07 manufactured in the in the same facility is as AXS-05?

So I'll take the first question and then I'll let Mark answer the second question. So with regards to MERIT data, as I mentioned, we received the data over the weekend. We have made the agency aware of the top-line results from the study. If they request to see additional data, we are prepared to provide it to them.

So hey Joe, its Mark. So for the manufacturing process for AXS-07, that actually is a bit more complicated and there are two facilities that we utilized for the manufacturer of the drug product. The drug -- the API 's are also available under open DMF too in the U.S. And of the two facilities that we used for drug product manufacturing, one of them is the same that we used for AXS-05.

Okay. Great. Thank you. And maybe just one more on the MERIT data that has been telling result in the patients that were switched placebo that did relapse. How quickly we would be seeing, is it pre-rapidly or was it towards the end of the six-month follow-up period connect initially totally can write on that would be helpful.

Yeah. So we will be presenting the full results at a [Indiscernible] of the conference, so we look forward to providing you all of the data there, including the relapse curve, so the Kaplan Meier curves, which will provide some of that information.

All right, great. Thank you very much.

Thank you. Our next question is from Joon Lee with Truist Securities, your line is open.

Hi, thanks for taking our questions. So at this point, given the produce [Indiscernible], is just a couple of weeks away. You think the most likely outcome is a CRL? And is that when you would find out what the deficiencies are? Just curious. What you think is the most likely outcome? And then another question on CMO, is there a strategic reason for not disclosing through the CMO is. We've seen companies who disclosing the CMO is and others who choose not to disclose of who the CMO is. So wondering what -- if that's based on any strategic or competitive advantage of not disclosing versus disclosing who the [Indiscernible] is. Thank you.

Yes, I'll turn it to Kevin who will answer your first question. And with regards to disclosing who our vendors are. That is something that we typically do not do. Different companies have different policies, but that is our policy. Kevin.

As mentioned earlier, there are couple of different potential actions that could occur between now and PDUFA date. We still have time, two weeks remaining until PDUFA. There is a possibility that approval is possible, labeling can proceed. There is also the possibility that the PDUFA date is extended If for example, the MERIT data is relevant for their review. And then the third option, as mentioned, a complete response letter and really based on what we know today which is we don't know what the deficiencies are. Those are the options that are available for the agency at this point.

Maybe a quick follow-up. Are there any obligations by the FDA regarding the level of disclosure interaction with the sponsor companies, in terms of communicating what those deficiencies are and best to facilitate the resolution of those deficiencies. I know the times are very tight, given, again PDUFA is only two weeks away. But just curious what you or the FDA could hope to achieve in those two short periods of time periods?

Yes. We can't comment on any kind of internal guidelines that the agency has but we certainly are trying to learn what the deficiencies are and it's not curiosity on our part. It's with a goal of addressing them.

Thank you.

Thank you. Our next question is from Yatin Suneja with Guggenheim Partners. Your line is open.

Hey guys. Couple questions from me, just clarifying. So I think it is our understanding that FDA doesn't engage with a sponsor after such a letter is issued because of the legal implication, but it seems like you are implying that you have reached out to them and there might be some engagement. So can you clarify? Did you hear anything from the FDA since that letter has been received?

Hi Yatin. So, what we've shared with you is that clearly, since we've gotten the letter, we've reached out to the agency to try and learn what the deficiencies are. And in response, what the agency has informed us of is that the review is still ongoing, that no final decision has been made on the review. And so we obviously still want to know what the deficiencies are so that we can address them, and once we know, we'll let you know.

Okay. And then the other question is with regard to the launch, like the [Indiscernible] you said, if approved pretty month after that you will be ready like, what's the [Indiscernible] factor?

So, given that this is our first launch of the Company, there are just general administrative hurdles that we have to clear prior to being able to distribute the product. And so that's the only reason for the delay.

Okay. And could you guys give any update on the narcolepsy study that's ongoing, and then the agitation study, what the status is in terms of enrollment? Thank you.

With regards to the narcolepsy study, we are on track to initiate a Phase III trial with that program this quarter. So stay tuned for that. And with regards to the Alzheimer's disease agitation trial, so enrollment there is going as planned. We are nearing 20% enrollment and which puts us on track to complete the study as previously guided in the fourth quarter of 2022.

Thank you.

Thank you. Our next question is from a Ashwani Verma with Bank of America. Your line is open.

Hi, thanks for taking our questions. Just a one on the AXS-05. So, I see here in the language in the PVR, I think it says preclude discussion of labeling and post-marketing requirements. Are there any other topics that are not precluded? That's my first one. And then the second is on the fibromyalgia drugs. So I think you mentioned that it's going to be filed in 4Q '22. There's some pending manufacturing and other activities. Can you elaborate on that a little bit? Thanks.

So thanks Ash for the questions. With regards to the first question around other topics being that may be precluded. So the letter specifically is with regards to labeling and post-marketing commitments, that's all it said. So, it's hard to interpret it fully without first getting additional details from the agency but what we've put in the release is the exact language from the letter. So you can read into that as you wish. With regards to fibromyalgia, the -- I'm sorry, what was the question?

Yeah, I'm just trying to understand, I think you mentioned that there's some pending successful completion of manufacturing and other activities. So I want to understand what, what does -- what needs to be done before it can be filed next year?

Yes. Sure. Maybe Kevin could provide some additional details there. But as a reminder, this is a new chemical entity. And so we actually are manufacturing the API and pentent (ph) to the active pharmaceutical ingredient. So clearly we'd want to make sure that we have enough scale to ensure a launch and filing. Kevin, any additional details there?

Yeah. Sorry. We're -- we need to establish and starting to establish our own facilities for the production of both the API and drug product and of course, the rate limiter is typically collection of stability data that would support the exploration dating for the product as we file an application. So a lot of it is just waiting for stability data to be accrued before we can file that application.

All right. Okay. Thank you.

Thank you. Our next question is from Chris Howerton with Jefferies. Your line is open.

Great. Good morning. Thank you for taking the questions. I think we've had a healthy discussion on the deficiency letters. So maybe I'll just ask about narcolepsy. So I think you're saying that we're going to have a Phase III study soon in the Fourth Quarter, so I guess the question is, is that how do you see the positioning of Reboxetine in the setting, I think that there's been some questions as to the significance of the cataplexy, and the breakthrough designation that was taken back, I guess as a result of Wakix achieving that label, so I guess how do you see Reboxetine positioning in narcolepsy first of all. And then the second question is with respect to the Phase III design, are there any features within that program that you're anticipating that can highlight some of those differentiations? Thank you.

In terms of the positioning of the AXS-12 and narcolepsy, it's important to remember that this is still an area of high unmet medical need. And so with the [Indiscernible] in now also having a label for cataplexy, that means that you only have two products that are approved to treat cataplexy. The other one being the oxybate salts. So still an area of high unmet medical need where most products are still scheduled. And most patients are not adequately treated. So we looking at AXS-12, the product profile is that not only did it have profound effects on cataplexy, which were rapid in all set, But it also rapidly impacted positively excessive daytime sleepiness. So not just the fact that it is addressing those two the key symptoms of narcolepsy, but also the speed of onset. Another important point of differentiation is that we did show an improvement in cognition, which is a symptom complex, which is very important to patients with narcolepsy, and which is not targeted by the products. And in our Phase 2 concert trial, we did show a rapid and highly statistically significant improvement in the ability to concentrate. As you can imagine, all of those endpoints would be studied in our Phase 3 program and we look forward to starting that trial in short order.

Okay. That's great. Thank you very much.

Thank you. The next question is from Matt Kaplan with Ladenburg Thalmann. Your line is open.

Good morning and thanks for taking the questions. Just wanted to talk a little bit about the deficiency letter. I guess, beyond the pivotal studies and long term safety studies, can you talk a little bit about the ancillary studies that were towards part of the NDA, did you have to complete likeability studies or an drug-drug interaction studies where those part of your package as well?

So we did not have to complete likeability studies and drug-drug interaction studies were definitely part of the package. So the package included a truly an array of clinical pharmacology studies. The drug-drug interaction studies would fall into that. And so it was very full, complete package.

Okay. Thanks. And then congrats on the MERIT study results. Can you talk a little bit about how the durability that you saw up to six months compares to some other available treatments for TRD are just MDD in general, in terms of durability that you saw?

Yes. It is hard to make up cross-trial comparisons but we are very excited by the durability. It's -- this is not new. I mean, we did show durability which is very impressive in the COMET trial. And their patients were treated for up to 12 months. So not only was there a rapid reduction in depressive symptoms, but it was maintained at out to 12 months of the treatment. So this is not new information and what's new is that even beyond that, patients were still stable and did not remit -- so did not relapse for an additional up to potentially 12 months. So, certainly at least 6 months, [Indiscernible] patients, 9 months. And this was in a randomized fashion. So wait, which lands obviously credibility to the data since it is controlled data.

All right. Thanks for the added detail there.

Thank you. Our next question is from Myles Minter with William Blair. Your line is open.

Hey guys, thanks for taking the questions. I'm just wondering in any of your previous interactions with the agency product filing whether that made mention of requiring efficacy demonstration across a broad range of depression patients and not just started but ended up in ASCEND and Gemini. Just asking that off the back of the Acadia CRL where the agency seems to want efficacy across multiple dementia subsets in that day our page road label.

And secondly, if that did come up as a deficiency and now we're kind of pointing towards STRIDE-1 being technically negative. Could you actually use the target sub study that you recently presented as a response to that deficiency if it showed up?

So, the answer is that has not come up in prior discussions with the agency. And it's hard for us to speculate since we don't know what the deficiencies are.

And then maybe just on the response right of the drug running period that was up to 12 months in MERIT. Was that similar to what we saw in STRIDE-1 or is that day that you're going to be presenting at a later medical conference. Thanks.

Let’s leave it at we have to analyze. So, when we looked at the comet data, so that study included patients not only to who had TRD, but it also included patients with other prior lines of treatment. And so it was the patients who had TRD -- who had TRD and who were in stable remission who were randomized into MERIT. So we'll have to do some calculations which we can do to provide you the exact answer to that. And we would anticipate providing that information when the date are fully presented.

Okay. Thanks for the questions.

Thank you. We have our last question from the line of David Hoang, with SVE. Your line is open.

Hey, good morning. Thank you for fitting me in. So just a couple of quick questions. So again, I realize this is going to be -- this is a little bit speculation here, but in the event you were to receive a CRL, can you just talk a little bit about sort of what the next steps would be there? Would you look to schedule with that meeting? And do you think there's anything in the MERIT study that you could potentially bring forth as you have supportive -- to be supportive of the application?

So with regards to Next Steps after a CRL, that is typically requesting a type-A meeting. So in that eventuality, that is exactly what we would do and we would do it and as quickly as possible. With regards to the usefulness of MERIT in under any scenario, it's very difficult to speculate since we do not know what the deficiencies are.

Got it. Understood. And then just one on AXS-14 for fibromyalgia. So, maybe just remind us but if I understand correctly the molecule originally -- the molecule originated with Pfizer development for some time. So just curious you know, as to what Pfizer never proceeded with filing for approval and they never saw an approval for the drug in fibromyalgia?

What we can tell you is that it was a decision which was made as part of a portfolio decisions. So that was disclosed by Pfizer, but we can tell you that it has nothing to do with -- it had nothing to do with the efficacy of the product or the safety of the product. And importantly, that portfolio decision was made before the readout of the positive Phase III trials.

Okay. Really helpful. Thank you for taking the questions.

Thank you. Since there are no more questions, I will turn the call back to Axsome's CEO for any concluding remarks.

Well, thank you all for joining us on the call today. We remain committed as always to advancing our portfolio of differentiated product candidates for the benefit of patients living with CNS disorders. We will keep you updated on the progress of our NDA for AXS-05 as we learn more, as well as on the rest of the pipeline.

Thank you.

This concludes today's conference call. Thank you for participating. You may now disconnect. Have a great day.
