Operator, Operator
Good day, ladies and gentlemen, and welcome to the COMPASS conference Third Quarter Call. As a reminder, this call is being recorded. And I would now like to introduce your host for today's conference, Steven Schultz. Sir, you may begin.
Steven Schultz, Senior Vice President of Investor Relations
Welcome all of you, and thank you for joining us today for our third quarter 2022 results conference call. We hope you've had a chance to review the two press releases we issued earlier today, summarizing our accomplishments this quarter and announcing the publication of the results of our Phase 2b trial for treatment-resistant depression in The New England Journal of Medicine. Again, my name is Steven Schultz, Senior Vice President of Investor Relations at COMPASS Pathways. And today, I'm joined by George Goldsmith, our Co-Founder and Executive Chairman; our Chief Executive Officer, Kabir Nath; Dr. Guy Goodwin, Chief Medical Officer; and Mike Falvey, our Chief Financial Officer. The call is being recorded and will be available on the COMPASS Pathways Investor Relations website shortly after the conclusion of the call. Before we begin, let me remind everyone that during the call today, the team will be making forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 as amended. You should not place undue reliance on these forward-looking statements. Actual events or results could differ materially from those expressed or implied by any forward-looking statements as a result of various risks, uncertainties and other factors, including those risks and uncertainties described under the heading Risk Factors in our quarterly report on Form 10-Q filed with the U.S. Securities and Exchange Commission and in subsequent filings made by COMPASS with the SEC. Additionally, these forward-looking statements represent our views only as of today and should not be relied upon as representing our views as of any subsequent date. We specifically disclaim any obligation to update or revise any forward-looking statements, even if our estimates or assumptions change. With that, I'll now hand the call over to George Goldsmith.
George Goldsmith, Co-Founder and Executive Chairman
Thank you, Steve, and welcome, everyone. It is with excitement and some sadness that I open this call as my final quarterly results call for COMPASS. I will serve as Executive Chairman through the end of this year to ensure a smooth transition and to continue to serve as Chairman of the Board thereafter. After my comments, I will hand the baton to Kabir, who will provide the business update, Guy will then cover our clinical progress, and Mike will provide a financial review. After our prepared comments, we will open the call to questions. I am pleased to report that we've made strong progress on our journey to create the future of mental health care. COMPASS has been a leader in developing innovative therapies, combining a powerful investigational drug candidate, psychological support and digital tools. We're running groundbreaking trials, already delivering promising results for treatment-resistant depression, and we're exploring new indications and avenues where clear patient need exists. We're joining forces with patients, health care providers, researchers and governments, so we can forge new pathways to better mental health together. And together, we have an enormous opportunity to make a difference in many people's lives. We created COMP360 psilocybin therapy, an investigational drug candidate combined with psychological support, that could be developed into a regulatory approved therapy that patients can rely on and have that therapy reimbursed by insurance. Our groundbreaking Phase 2b trial with COMP360 psilocybin therapy in patients suffering with treatment-resistant depression provides the scientific rationale to announce a robust Phase 3 program, which has now had several clinical sites initiated. This Phase 2b trial received strong validation through today's publication in The New England Journal of Medicine. We're honored to have the leading peer-reviewed medical journal publish not once but twice about COMP360. I want to express my gratitude to those of you who have supported our work or will do so in the future. Everyone has a story. Working together, we can improve the outcomes of these stories. With that, I turn today's program over to Kabir Nath, COMPASS Pathways Chief Executive Officer, who will lead us through today's program.
Kabir Nath, Chief Executive Officer
Thank you very much, George, and good day to everyone. It's now been just over three months since I took over as CEO of COMPASS Pathways, and it's certainly been an exhilarating learning experience. Even with my prior exposure to COMPASS through my work at Otsuka, including their investment in the Series B round in 2020, I found the level of activity and accomplishment here extraordinarily high, particularly as we finalized the design of our Phase 3 clinical program, and presented it to you on October 12 during our Capital Markets Day. In that program, we covered not only the Phase 3 design, but also several other important aspects of our work, including our approach to psychological support and digital tools, as well as the advanced work we are already doing to ensure successful commercialization. I urge you to view the archive of that program if you've not already done so. One of the most striking things in preparing for that presentation was for me to understand the depth and breadth of experience that the executive leadership team here at COMPASS brings to our mission. These qualities, their passion and their commitment to the vision of COMPASS were all evident in the team's presentation on Capital Markets Day. As we look forward to the start this year of our Phase 3 program for patients suffering with treatment-resistant depression, my main priority will be to move COMP360 psilocybin therapy successfully through the clinical trial, regulatory and reimbursement processes. We will also ensure that it's delivered into health care systems together with psychological and digital support to patients who urgently need it. At Otsuka, I had led the development and commercialization of pharmaceutical products and digital solutions addressing complex mental health needs and so gained significant experience in integrating pharmaceutical products with digital support. I'm very happy to report that in this really complex area, the COMPASS team is executing very well and focused on the right areas to ensure success. I'm also pleased to report to you that during this quarter, COMPASS continued to make steady progress towards preparations for our Phase 3 program. We've been bringing both experienced and new clinical sites online and also adding to our cohort of trained therapists, with very active recruitment and training underway. In the quarter, we also completed the analysis of our Phase 2b long-term outcome study, which Guy will share with you in a moment. Beyond our Phase 3 program in TRD, we have two ongoing COMP360 Phase 2 trials in anorexia nervosa and post-traumatic stress disorder, or PTSD. TRD and PTSD represent large patient populations that are underserved by existing treatment options. Anorexia nervosa is also an area of very high unmet need. It has the highest mortality rate of any psychiatric disorder and to date, no medicines have been approved to treat this. With that, let me now turn to Guy who will provide his thoughts on the next steps in our planned Phase 3 program and also discuss the Phase 2b long-term outcome study.
Guy Goodwin, Chief Medical Officer
Thank you, Kabir, and good day, all. Let me begin by reviewing our Phase 3 pivotal program design, the details of which we communicated during our Capital Markets Day presentation, which is available on our website in the Investors section. As a high-level overview, we are focused on building an overall data set, which will form the cornerstone of our new drug application with the FDA. We are also looking beyond the approval to launch as well by generating the evidence that we believe will support reimbursements for this novel treatment at scale. Our pivotal Phase 3 trials are designed to answer two important clinical questions. First, can we replicate and reconfirm the compelling treatment response exhibited in our Phase 2b trial? And second, what is the impact of an additional dose on the number of responders and the quality of the response seen in the Phase 2b trial? To generate the data that answers these questions, we will conduct two clinical studies: a single-dose monotherapy trial we've named COMP 005; and a fixed repeat-dose monotherapy trial named COMP 006. These designs can answer additional important questions such as, how does the safety profile of COMP360 compare to placebo? And how may the response differ between one dose and two doses of 10 milligrams or 25 milligrams? We also recognize the need to look at a long-term follow-up study that may include elements of durability and retreatment. Let me point out that the robustness of the Phase 2b trial, 233 patients in 22 sites in 10 countries and seven languages, provides us with confidence that we can deliver a successful Phase 3 result. Our Phase 2b trial went far beyond the scope of what traditionally have been smaller, signal-generating studies. The Phase 3 patient population will also be essentially the same as in our Phase 2b trial. That is the same definition of treatment-resistant depression and the same core inclusion and exclusion criteria, which aids in our extrapolation from the Phase 2b trial to our Phase 3 trial size and powering. Both of our pivotal studies have a primary endpoint of change from baseline in MADRS total score at week 6. The week six endpoint is consistent with previous trials in depression. We will also be observing the patients at periodic points along the way to the week six endpoint measurement. Providing more detail on the pivotal trial, COMP 005 is a single-dose monotherapy trial comparing a 25-milligram dose of COMP360 versus a true placebo. Drawing upon the experience with Phase 2b and the treatment effect we observed, and taking into account a 2:1 randomization to 25 milligrams, we have determined a trial size of 378 patients. We expect that top line data from this trial will be available by the end of 2024. The second pivotal trial is the fixed repeat-dose monotherapy COMP 006 trial with three arms comparing COMP360 doses of 25, 10 and one milligram. Patients will receive the same dose at day one and at week 3. With the three dosing arms and the 2:1:1 randomization, we have determined a trial size of 568 patients. Top line data is expected to be available in mid-2025. The third Phase 3 program trial is a long-term observational follow-up study, the design of which will be influenced by the observations and results of the Phase 2b follow-up study which we announced today in our quarterly results. The 66 patients entering the Phase 2b follow-up study were in varying states of response and may not have been fully representative of the main study population. These limitations demand caution so that our conclusions are preliminary and require confirmation in the larger follow-up study we will conduct in Phase 3. The primary endpoint of this Phase 2b follow-up was the median time to a new depressive event. Depressive events are, for example, initiation of new antidepressant treatment, hospitalization due to depression or suicidality, MADRS worsening, discontinuing for adverse events or lack of efficacy. The time to such an event was longer, 189 days, for the COMP360 25-milligram group compared to the COMP360 1-milligram group at 21 days and the 10-milligram group intermediate at 43 days. The small group in the study that initially responded or remitted with COMP360 25 milligrams appeared to have durability up to approximately six months. 27 or 40.9% of participants had an adverse event that was ongoing or started after week 12, and a lower proportion of participants started new treatments for depression in the 25-milligram and 10-milligram arms versus the 1-milligram arm. Suicidality, which is a regrettable risk in this population, was recorded as an adverse event twice in the 25-milligram group, twice in the 10-milligram group and once in the 1-milligram group. These findings also dovetail into our investigation of what a second administration of COMP360 may achieve regarding durability, response and remission. It will give us additional safety information beyond the more than 500 participants who have been exposed to COMP360 so far. And with that overview, Mike, I hand it over to you.
Mike Falvey, Chief Financial Officer
Thank you, Guy. I will now recap our financial results for the three months and nine months ended September 30, 2022. For the three months ended September 30, 2022, net loss was $18.4 million or $0.43 per share compared with a net loss of $15.8 million or $0.38 per share during the same period in 2021. These results include noncash share-based compensation of $3.5 million in 2022 and $2.3 million in 2021. For the nine months ended September 30, 2022, net loss was $60.6 million or $1.43 per share compared with a net loss of $46.1 million or $1.17 per share during the same period in 2021. These results included noncash share-based compensation of $9.8 million in 2022 and $5.9 million in 2021. For the three months ended September 30, 2022, R&D expenses were $14 million compared with $12.2 million during the same period in 2021. The growth was attributable to increased personnel and noncash share-based compensation costs as a result of hiring to support our digital and clinical programs in addition to external consulting expenses. This increase was partially offset by a slight decrease in external development expenses attributable to decreased clinical trial expenses, which we expect to increase substantially in the near future as we initiate our Phase 3 program. For the nine months ended September 30, 2022, R&D expenses were $45.3 million compared with $30.4 million during the same period in 2021. For the three months ended September 30, 2022, G&A expenses were $11.6 million compared with $9.6 million during the same period in 2021. This growth was attributable to increased personnel and noncash share-based compensation costs due to increased headcount, as well as increases in legal and professional fees, facilities costs and other expenses. For the nine months ended September 30, 2022, G&A expenses were $33 million compared with $24.5 million during the same period in 2021. COMPASS continues to maintain a strong financial position with cash and cash equivalents of $173.1 million at September 30, 2022 compared with $273.2 million at December 31, 2021. The change in cash of $100 million over the first three quarters was due to cash used in operations of $60 million and a change of $40 million due to the impact of exchange rates on our cash balances held in British pounds. We hold our cash balances in dollars, pounds and euros in proportion to our spending plans in each currency. The pound depreciated significantly against the dollar over the second and third quarters. And as a result, our pound deposits translate into fewer dollars on our financial statements. Since we intend to spend these pound balances rather than exchange them into dollars, the pound's depreciation is not expected to impact our operations or our cash runway, which continues to extend into 2024. We view our strong balance sheet as an important strategic aspect which we intend to manage carefully as we invest to advance these promising potential therapies while at the same time continuing to create value for our shareholders. Thank you, and I'll now turn the call back to Kabir.
Kabir Nath, Chief Executive Officer
Thank you, Mike. In closing, we're excited to be moving into Phase 3 with our core program for COMP360 psilocybin therapy in treatment-resistant depression. We've shown you that we have a robust, comprehensive program which will answer key strategic questions around durability and the value of retreatment, and which builds on the compelling data we demonstrated in Phase 2b. We're confident that these answers will support both the COMP360 psilocybin therapy regulatory approval, but also provide the evidence needed by payers to reimburse this new therapy upon launch. This strategy is highly differentiating in our area of funds and will lead to significant value creation over time. In our Capital Markets Day presentation, which I remind you is archived on our website in the Investors section, we offered views into aspects of our business that have not been covered in depth previously. Specifically, we spoke about our commercial strategy and the extensive work underway to prepare for a COMP360 launch, plus our advanced digital initiatives, and the innovative tools which support safety and optimize the experience for patients and provide support, rigor and consistency for therapists. As George has often said and as I will continue to reinforce, our goal here at COMPASS is to turn our vision of building the future of mental health care into a reality. As we enter the final stage of pivotal development in TRD, our sites are set on achieving this goal, improving patient outcomes and creating value for health systems by combining our medicine with psychological support and digital innovation. We'll now open the line for questions. Operator, please?
Operator, Operator
Our first question will come from Charles Duncan of Cantor Fitzgerald. Your line is open.
Charles Duncan, Analyst
Thank you, George and team Kabir, for answering our question, and congratulations on the publication in The New England Journal. It's great to see. I have a couple of questions regarding the pipeline. For the long-term observational study you mentioned for Phase 3, does it need to be completed before an NDA is filed? If not, could you clarify when the filing might happen after the other two Phase 3 studies? Also, Guy, you went through that section rather quickly. I want to confirm that the time to depressive events for 25 milligrams was approximately 189 days, and I believe you mentioned 21 days for the one milligram? You adjusted the order slightly.
Kabir Nath, Chief Executive Officer
Thank you, Chaz. So let me ask Guy just to fix that second point first, and then I'll come back to your first question.
Guy Goodwin, Chief Medical Officer
Yes. Thank you, Chaz. You heard correctly that the difference between the one and the 25 was 180 versus 21 days, yes.
Kabir Nath, Chief Executive Officer
And in terms of the first question, obviously, it's a bit premature to speculate on our overall regulatory strategy right now. But we view 005 and 006 as the pivotal trials from a regulatory perspective. Typically, the observational follow-up would indeed be that. Clearly, it's very important to continue to monitor for new safety events, in particular, but you should regard the pivotal packages, 005 and 006, that should be the base case.
Charles Duncan, Analyst
I have a clarification regarding the Phase 2b long-term observational study. Were the patients who enrolled or rolled over to the open-label extension equally representative across the three groups? Additionally, could you provide some details on that? When do you expect to present the data? This is very interesting.
Guy Goodwin, Chief Medical Officer
Well, quite simply, the response rate among the patients was not the same as that of the overall population at three weeks. There was certainly some lack of representation in the patients who rolled over. Additionally, the sample sizes in each category were relatively small. Therefore, we are going to be very careful not to overinterpret our data, as we believe the field has enough of that already. We plan to publish our findings cautiously. This supports the main conclusion but is limited in the extent to which it adds to the primary outcome.
Charles Duncan, Analyst
I understand. So it's really more conclusive regarding the Phase 3 program?
Guy Goodwin, Chief Medical Officer
The Phase 3 program will have the numbers and the incentives for patients to join this trial, which I think will be important for getting a really representative group of patients on whom we can base, really, important plans about how to deliver this treatment in practice with retreatment, et cetera.
Charles Duncan, Analyst
Very good. Last question, 005 in terms of time to data end of '24. I guess I'm wondering if you could provide us some thoughts on what is really governing that time? Could it prove to be overly conservative?
Guy Goodwin, Chief Medical Officer
We certainly hope so. I know we're very much in the hands of others in this regard. We think we have a realistic and conservative plan. And of course, if it delivers before that actual time that we've given, we'll be delighted.
Charles Duncan, Analyst
Well, I'm sorry, is it enrollment? Or is it therapist availability or something outside of, say, the patient population?
Guy Goodwin, Chief Medical Officer
I mean we can't really say what we'll be limiting in any individual site. But the overall rate of recruitment, we believe, will be satisfactory to deliver on the times that we've given.
Charles Duncan, Analyst
Very good. Thanks for taking my questions.
Guy Goodwin, Chief Medical Officer
Thanks.
Operator, Operator
Thank you. One moment please for our next question. Our next question will come from Neena Bitritto-Garg of Citi. Your line is open.
Neena Bitritto-Garg, Analyst
Hi guys. Thanks for taking my question. So just another follow-up question on the Phase 2b long-term data that you talked about earlier. I know, Guy, you mentioned that in the small group of initial responders or remitters, durability appears to be sustained out to six months. I guess can you just define what exactly you mean there? Like what proportion of the patients who were responders and remitters at week three were actually able to sustain that response out to six months? And then just a question on The New England Journal publication. I noticed that it looked like patients who had higher severity on HAM-D17 at baseline performed pretty similarly on change from baseline in MADRS versus those who had less severe disease at baseline, and so I'm just curious if that's kind of consistent with what you had expected.
Guy Goodwin, Chief Medical Officer
If I could address the second question first, you raise an interesting point about the trials that attempt to differentiate between higher severity illnesses and lower severity ones. We were pleased to find that there was actually no difference between the severe and moderate groups. While we believed that the severe groups would provide a significant advantage, this is not always the case in other trials, especially in major depressive disorder. We are focused on treatment-resistant depression, which alters our perspective and expectations somewhat. Overall, it was encouraging to see a quality effect and positive news for patients in both groups. The main issue lies with the numbers; they are small, and we are not publishing them in great detail at this stage. It’s difficult to determine the exact number of patients in the phase study since we are unsure if we have a fully representative group among the 25 patients going into follow-up. However, those who did continue showed scores that were either half of the original baseline score, which indicates a response, or were in remission up to six months after dosing. We can conclude that among the patients we observed who responded and remained in remission at 12 weeks, they continued to show that remission at six months in the 25-milligram group. Keep in mind, though, it’s a very small number, and beyond that timeframe, we lose participants for various reasons. It is generally challenging to retain participants in the study with limited incentives, leading to very small sample sizes. Thus, beyond six months, we cannot make significant statements.
Neena Bitritto-Garg, Analyst
Okay. No, that's super helpful. Can you just remind us, too, how many people actually entered the open-label extension for the extension period?
Guy Goodwin, Chief Medical Officer
So it's about 20 in each of the three groups, although it was 66 initially, which included patients from the study with SSRIs. They included a few patients from that group. We were looking at about 19 patients in each of the groups. While others have highlighted the outcomes of those numbers, we're hesitant to draw conclusions from them.
Neena Bitritto-Garg, Analyst
Got it. Okay, that's helpful. Thank you.
Operator, Operator
Thank you. One moment please for our next question. And next, we have Ritu Baral of Cowen. Your line is open.
Ritu Baral, Analyst
Good morning, everyone. Thanks for taking the questions. Guy, forgive me, I've got a quick follow-up to Neena's question again just on these figures and the idea that these are not representative patients. Is your comment on the representativeness based mainly on the response rate to the treatment seen in the blinded portion? Or is it a function of sort of as you look at the baseline of these patients versus the overall baseline of everybody heading in that makes you believe it's not representative?
Guy Goodwin, Chief Medical Officer
It's entirely based on the response rates. We're just concerned that we don't have a fully representative group. The individuals are eligible patients; there's nothing wrong with them as patients. However, as a group, their composition differs somewhat from the actual makeup of the 233 patients in the blinded phase of the trial. The extrapolation is a bit tricky, especially when you have 19 patients.
Ritu Baral, Analyst
Okay. Got it. That makes sense. Regarding this Phase 3 program, has the FDA mentioned any requirements for treating patients on background SSRIs as part of the Phase 3? Will those patients be included in the long-term follow-up? Or is there a certain group of patients or cohorts that you might permit in studies 005 or 006?
Guy Goodwin, Chief Medical Officer
Not in 005 and 006. We're still thinking about the long-term follow-up, and we'll announce that in due course.
Ritu Baral, Analyst
Got it. Regarding the fixed repeat-dose study, how should we interpret what the top line data will indicate for the two doses? Considering the evidence you have and the details available, do you anticipate better efficacy rates at three weeks or six weeks? Or do you think that the combination of double doses and double treatment will have a greater impact on durability?
Guy Goodwin, Chief Medical Officer
Well, it's a good question, and it's the reason we're doing the work. So I think we can have a hypothesis, which is that we will see higher rates of remission after two treatments, particularly at 25. It will be very interesting. We simply don't know about the 10 milligram, that's why we're doing the study. And durability, yes, we'd be delighted if it turns out to be the case, but we don't have a hard and fast prediction on that.
Ritu Baral, Analyst
Got it. Thanks for taking all the questions.
Operator, Operator
Thank you. One moment of our next question. The next question will come from Patrick Trucchio of H.C. Wainwright & Company. Your line is open.
Patrick Trucchio, Analyst
Hi, good morning. I have a follow-up question on the Phase 3 COMP360 program in TRD. I think one of the changes for the Phase 3 from the Phase 2 is the need for one person to provide psychological support rather than 2. So I'm wondering if, first, can you confirm that change? And then can you discuss the implications of the change including the regulatory input received regarding it? And how it would be expected to impact the Phase 3 program and eventual commercialization?
Kabir Nath, Chief Executive Officer
Thank you, Patrick. This is Kabir. I can confirm that for the administration session, only one therapist will need to be present. Without going into detail about our regulatory strategy, it's not our intent to ask the FDA to oversee psychological support, as that falls outside their role; their focus is on regulating drug therapy. This does allow some flexibility in how psychological support is administered, but it needs to be aligned appropriately. It’s important to note that a trial setting differs significantly from the potential commercial setting. During the trial, we prepare patients for various doses, which requires a different level of preparation and expectation. We are currently exploring how to adjust this for commercialization. As we mentioned on October 12, we are also investigating ways to optimize psychological support in potential treatment sites, including chains of clinics and ketamine clinics, as we progress in parallel with the Phase 3 study to enhance the psychological support component.
Guy Goodwin, Chief Medical Officer
Can I add, Patrick, that I think it's also key and it's not sometimes appreciated that the psychological support is offered equally across the three or the two arms of the study. So any differences we observe are clearly attributable to the drug. I think sometimes there's a certain amount of confusion about that. So irrespective of what the psychological support is, it's equal across the three arms, and the difference is that emerge in the trial or due to the drug differences.
Patrick Trucchio, Analyst
That's helpful. I have a follow-up regarding the therapists in the Phase 3 program. Could you provide insights into their training process? Is it aligned with the previously published COMP360 protocol? Do they have to complete a certain amount of training, or is it perhaps streamlined? Is prior experience with administering psychedelic medicines required? How quickly do you expect the ramp-up to progress to ensure timely enrollment in the studies? Lastly, will there be any anticipated synergy or benefit from training these therapists, allowing them to participate in other COMP360 trials for different indications, such as PTSD and anorexia?
Kabir Nath, Chief Executive Officer
Yes. So Patrick, let me try and take those elements in sequence. So first, the training is similar to what we provided in the Phase 2b, but we have streamlined it and, in particular, a lot more of it is delivered online. So therapist companion, which is the app that is designed to work with therapists, enables us to deliver significant amounts of that online. But yes, there is still a tailored training requirement for therapists to participate in the Phase 3 trial. In terms of the recruitment of therapists, the way we do it is we clearly identify sites and the sites themselves. One of the criteria is that the sites themselves have competent therapists that they are used to working with, and they nominate the therapists. They then go through a qualification process with us, followed by the training. For Phase 2b, we used around 65 therapists. For Phase 3, we will need to use somewhere in the order of 250. As mentioned in the prepared remarks, we're already well underway with actually interviewing those that have been identified by new sites and training them. And I actually do not see that as any sort of barrier in terms of getting recruitment in place. I think we're confident of that from a therapy perspective. Yes, we would envisage the same therapists, potentially being able to support other indications. Though recognize, that particularly for anorexia, there is likely to be some different training content. It is a very different disease from treatment-resistant depression. And then I think the final thing I'd just say is, clearly, the cohort of trainers in Phase 3 will be the nucleus of what could be the commercial cohort. And also we are looking to identify, train the trainers and mentors among these who can actually help us then build scale in the therapy network.
Patrick Trucchio, Analyst
Yes, that's really helpful. Thank you so much.
Kabir Nath, Chief Executive Officer
Thank you, Patrick.
Operator, Operator
Thank you. One moment for our next question. Our next question will come from François Brisebois of Oppenheimer. Your line is open.
François Brisebois, Analyst
Hi, thank you for taking the questions. I have one to start. Regarding the transition from a 1-milligram placebo equivalent to a true placebo, I'm curious about the effect. There shouldn't be much difference, but how do you address the situation where patients might not realize they aren't receiving any substance, compared to a trial where the 1-milligram placebo clearly indicates they are getting some psilocybin?
Guy Goodwin, Chief Medical Officer
Yes. Thank you. You make a very good point. I think the dilemma is that the only way to establish a true safety baseline is to use placebo. Obviously, the patient experience is something that we're going to try and understand, and we're going to look at expectations and just how that relates to outcome. Obviously, placebo is not without an effect in depression. And in fact, it is often a big problem in depression trial, to put it mildly. And we expect that the whole experience, the multiple visits, the long time in a pleasant environment, even the introspection, which we know that some people actually find very immersive, is not without an impact. So we will be interested to see what happens. And it's also worth saying that some people who get 25 actually don't get much of an effect either. So it's not a completely cut and dried. But it's clearly, as you're indicating, it's more different than in the case of one milligram versus 25. But it's really the only way we can do the necessary safety baseline.
François Brisebois, Analyst
Okay. Okay. No, that's helpful. And then in terms of the new space, just to add on a little bit to Charles' question maybe in terms of barriers to enrollment, like any trial has sometimes. Have you ever run into the issue with sites or PIs from sites or certain therapists that just there's a different thought process, because this is so new between believer sites, maybe or more skeptical sites in terms of your enrollment? Or has a lot of maybe the initial skeptics, post the Phase 2b data, are actually probably more excited now to join the study? Just thinking enrollment here.
Guy Goodwin, Chief Medical Officer
We have some very enthusiastic sites. If you watched the Capital Markets Day, you will have seen an example of that. We're not looking for sites that aren't excited; we want people who are eager to recruit. Initially, there was some skepticism in the original PI group, but I haven't heard any pushback on our interpretation of the findings, and they have been happy to be co-authors. All of the individuals who significantly contributed to the study were co-authors in the New England Journal paper. So, we have a strong foundation to progress to other sites, which will receive our educational input about the experience and outcomes from Phase 2. Therefore, I don't think we need to be overly concerned about this; I believe it's not going to be a major issue.
Kabir Nath, Chief Executive Officer
No. Thank you. I would just like to remind you that it's crucial for us to collaborate with many sites that lack experience in psychedelics. This is important for generalizability, and we observe that. In our IIb trial, we are limiting the number of patients with prior experience, but having sites without previous psychedelic experience is also vital for generalizability. Additionally, I want to reinforce that we do not view this as a significant barrier in the recruitment process.
François Brisebois, Analyst
Understood. Lastly, regarding the regulatory filing, you mentioned that you view the two Phase 3 studies, excluding the extension, as pivotal. I am curious about the outcomes and learnings from the repeat dose. Is there a possibility that one outcome could be considered more significant than the other? Ultimately, can you proceed with the filing based on just one positive outcome, or is it necessary to have both?
Kabir Nath, Chief Executive Officer
It's a fair question. But again, I mean, I think, as Guy answered to an earlier question, we have to run the trials. We can't answer that question in the abstract. We have designed a program that we think between these two trials answers key questions around, you know, what does a repeat dose do perhaps in terms of efficacy and durability, as well as the pure placebo comparison from a safety perspective. But honestly and truly, until we run both the trials and seen the data and discussed with the FDA, that would be a review issue.
François Brisebois, Analyst
Okay. Thank you. And congrats on the publication.
Kabir Nath, Chief Executive Officer
Thank you.
Operator, Operator
Thank you. And one moment for our next question. The next question will come from Bert Hazlett of BTIG. Your line is open.
Bert Hazlett, Analyst
Thank you for the question, and congratulations on the publication. I'd like to revisit the time-to-event analysis and the Phase 2b follow-up. Specifically, I'm curious about the data magnitude and the differences observed. If these results can be replicated, based on your conversations with payers, do you believe this data will be enough to support the reimbursement levels you anticipated for this program?
Kabir Nath, Chief Executive Officer
Thank you, Bert, that's a really good question. So I think a couple of points. I mean while we've clearly had a number of discussions with payers around our overall strategy involved, we have not yet advanced to the point of that sort of level of detailed discussion of really talking our value models in detail, let alone actually putting a price into them to discuss with payers. So it's somewhat early for that. I think as Guy has said, we would be wary of reading too much into 004 as an evidence base. But I think with what we are designing in 005 and 006, and the fact that there will be available at the time of talking to payers, some data from 007 from the long-term observational, I'm confident that we will have enough data for the basis of those discussions. But I wouldn't say that we have it yet.
Bert Hazlett, Analyst
That's helpful. And so would you consider then this type of data central to that discussion? Or is it maybe more of a focus on remission? Or could you just give us maybe a little bit more about how you're thinking about building in a reimbursement argument, if you will, into the Phase 3 program?
Kabir Nath, Chief Executive Officer
So I think the first place we would start is simply the efficacy and safety of either or even a single dose or potentially repeat dose relative to anything else that is available for patients with treatment-resistant depression. So I think at first base, we have a very compelling traditional value argument around the benefit we bring in treatment-resistant depression. I think that as we get closer, as we actually see the data from 005 and 006, thinking about how we might explore more innovative discussions around reimbursement, around the potential of treating remission and what that looks like from a value perspective, those are certainly all options. But candidly, until we've generated the initial data, it's premature to talk about what that strategy might be.
Bert Hazlett, Analyst
Terrific. And then just one more quick one. I'm not sure whether I missed the potential timing of the readouts for Phase 2 in PTSD and anorexia nervosa. If there's any guidance there, that would be helpful.
Kabir Nath, Chief Executive Officer
In the latter part of next year, late '23.
Bert Hazlett, Analyst
Thank you very much. Congrats again.
Operator, Operator
Thank you. One moment for the next question. Our next question will come from Esther Hong of Loop Capital. Your line is open. Thanks.
Esther Hong, Analyst
Hi, good morning. Thanks for taking my questions. So I wanted to know, first, how did the long-term data inform the repeat-dosing study, so 006. And then a clarification on how many days out for the 10 milligram, I know there's about 189 for the 25 milligram and 21 for the one milligram. And then I've got a follow-up on training.
Guy Goodwin, Chief Medical Officer
Okay. The intermediate number was about 50 days for the 10 milligram, if you want to compare it with the 21 and the 180. So it was intermediate. And in a sense, what this is reflecting is the pattern of response in the first 12 weeks as you can kind of see. Sorry, what was your first question?
Esther Hong, Analyst
So how did this data inform the repeat-dosing study?
Guy Goodwin, Chief Medical Officer
Okay. I'm not sure if it's fully informed it really. I mean the repeat-dose study was really based on our considerations of the 12-week data and the full data set. I mean this follow-up element, as you've heard me say, is something that we are not taking as being very definitive, but simply supportive of what we had already concluded from the Phase 2b 12-week study.
Esther Hong, Analyst
Great. As a follow-up, these patients will have placebo, which is probably the best measurement, but in the real world, do clinicians, specifically practicing prescribers, want to see the potential for how this is used in combination with SSRIs or antidepressants as a backup? Will they be interested in seeing more data similar to the study you conducted previously?
Guy Goodwin, Chief Medical Officer
Well, knowing clinicians, the simple answer is, yes.
Kabir Nath, Chief Executive Officer
Just to build on that, I mean, it is a great question. I mean we have deliberately made the choice, as we said earlier, that these are monotherapy trials. We think that is still needed in order to truly demonstrate the efficacy and safety of COMP360 psilocybin therapy. But we do not intend to run a significant adjunct program as a randomized trial. But as Guy says, we recognize the reality of what use will be. And again, you can expect us over the next few years in parallel with the randomized trials to be looking at real-world studies and other things that may actually help to answer that question. But yes, we recognize the reality of real-world use.
Esther Hong, Analyst
Got it. As a follow-up to Patrick's question about training, I wanted to ask if there is any overlap in the training of therapists for MAPS' Phase 3 MDMA program for PTSD and COMPASS' COMP360, which could result in more therapists being trained by both sponsors.
Kabir Nath, Chief Executive Officer
I can't comment on how MAPS is selecting or training therapists because I'm not fully informed on that. However, we are very focused on the sites we collaborate with, and they nominate the therapists. We then assess and train those therapists ourselves. Looking at the broader picture, in the long run, we hope and believe that many of these different molecules will be successfully approved for various diseases. It seems unlikely that there could be tailored training for each molecule for every indication. As this field continues to develop, and as other companies progress to Phase 3 and beyond as we have, I believe you will see this evolve. For now, our focus is on the therapists necessary for our programs, and we are managing that independently.
Esther Hong, Analyst
Thank you.
Operator, Operator
Thank you. One moment please for our next question. The next question will come from Sumant Kulkarni of Canaccord Genuity. Your line is open.
Sumant Kulkarni, Analyst
It's nice to see a publication. Thanks for taking my questions. I have two, both on the COMP360 Phase 3 design. First, do you expect to conduct an interim analysis on your COMP 005 Phase 3 trial?
Guy Goodwin, Chief Medical Officer
We don't expect to, no.
Sumant Kulkarni, Analyst
Second, at this time, we know you've chosen a fixed repeat-dose trial, that 006, with a relatively short time between the first and the second dose. So either in your internal deliberations or those with the FDA, did this design compete at all with an as-needed repeat-dose design over the course of the year, for example? Or which would be somewhat similar to Sage's SHORELINE program on zuranolone, that's a noncyclic compound, obviously, for MDD, but has some commonality in that it has elements of episodic therapy for a condition that's currently treated chronically?
Kabir Nath, Chief Executive Officer
Yes, it's a good question, Sumant. I think we recognize that we're still in the relatively early stages of demonstrating the profile of COMP360. The decision here was to address the question that came up repeatedly after the Phase IIb trial, which is the effect of a repeat dose. That is what we've aimed to answer in study 006, particularly whether it can enhance efficacy or durability. We are especially interested in the impact of two 10s, given that 10 was not an effective dose in the Phase IIb trial.
Sumant Kulkarni, Analyst
Got it. And I'll squeeze one in on the anorexia trial. Do you think the EDE scale is sensitive enough to pick up differences in maybe direct conditions post-dosing, because this is such a different kind of treatment paradigm compared to the typical dosing paradigm, I would guess, in anorexia?
Guy Goodwin, Chief Medical Officer
Yes, that's a great question, and we've been concerned about that. That is the scale that has been used in psychotherapy trials. Obviously, we start with where the light is. We've added clinical global impression, which will evolve from a detailed analysis of the EDE. If someone conducts an EDE, they will have a solid basis for making a clinical global impression. We've also started a program, since we are in Phase 2, where a certain amount of experimentation is allowed. We're looking into how to develop scales for a Phase 3 program. You are absolutely right to highlight this, and we are addressing it.
Sumant Kulkarni, Analyst
Thank you.
Operator, Operator
Thank you. One moment for the next question. The next question will come from Jason McCarthy of Maxim Group. Your line is open.
Michael Okunewitch, Analyst
Hi guys. This is Michael Okunewitch the line for Jason. Thank you for taking the questions. So I guess the first one, I just wanted to ask on the bifurcated Phase 3 program. I'd be interested to see how your initial thoughts on how it might work out for labeling and for commercial use in a scenario where you have improved efficacy on the dual dose, but it's still significant on the single dose. Would you expect this to result in perhaps two different approved protocols? And would you be looking at any potential digital biomarkers to kind of predict which patients would be likely to benefit from that repeat dose?
Kabir Nath, Chief Executive Officer
That's a great question. We are in the early stages of figuring out our ultimate regulatory strategy. However, it's easy to imagine a broad label for the treatment of treatment-resistant depression that encompasses various studies. Our expectation is that psychiatrists will want considerable flexibility regarding dosing and related matters. Regarding the digital aspect, we definitely see it as part of our future, which we mentioned during our Capital Markets Day. Specifically, in Phase 3, we plan to test many of our hypotheses by collecting digital markers from patients using the myPathfinder app, with patient consent, of course. We will utilize Phase 3 data to evaluate these hypotheses. Therefore, I do not anticipate that we will have digital support at launch to determine which patients might be categorized for a single dose or repeat dosing. However, this is certainly part of our long-term goals.
Guy Goodwin, Chief Medical Officer
I think I would add that we're going to also learn from the patient experience from whether or not one or two is preferable, and that will be invaluable in thinking about the commercial.
Michael Okunewitch, Analyst
All right. And then just as a follow-up, given what you saw in the open-label extension over the time of the depressive event of around six months, are there any thoughts towards running a study to evaluate the long-term repeat dosing, such as dosing after a relapse, possibly at a post-marketing study to maybe support with reimbursement?
Kabir Nath, Chief Executive Officer
I think that's a great question. And again, I'll be candid. Right now, we've been focused on the pivotal programs. We know that they will answer some of the questions, but by no means all the questions. The long-term follow-up of these two will perhaps enable us to answer some of that what you've asked, but I would expect that you would see, whether it's COMPASS-sponsored post-marketing trials or other potential trials, real-world trials, that actually attempt to answer questions like that around treat to remission or repeat at some point. And again, to build on your earlier question, clearly, having digital markers available would be both very relevant and very helpful to try around that.
Michael Okunewitch, Analyst
Thank you very much. I really appreciate the additional clarity. Thank you.
Operator, Operator
Thank you. I see no further questions in the queue. I would now like to turn the conference back to management for closing remarks.
Kabir Nath, Chief Executive Officer
Thank you very much, everyone. Thank you for the questions today. I think, again, this is a very big day for us with the publication in The New England Journal, which we're incredibly proud of. And again, reiterate the fact that we are excited that we are entering now the final phase of development for treatment-resistant depression. We have lots of opportunity to make a serious difference in outcomes for patients with serious mental illness. So thank you for your support. Have a good day, everyone.
Operator, Operator
This concludes today's conference call. Thank you all for participating. You may now disconnect, and have a pleasant day.
