Good day. Thank you for standing by. Welcome to the Compass Pathways Q1 2023 conference call. At this time, all participants are in a listen-only mode. After the speaker's presentation, there will be a question and answer session. To ask a question during the session, you will need to press star one one on your telephone. You will hear an automated message advising your hand is raised. To withdraw your question, please press star one one again. Please be advised that today's conference is being recorded. I would now like to hand the conference over to your speaker today, Steve Schultz. Please go ahead. Welcome all of you, and thank you for joining us today for our Q1 2023 results conference call. Again, my name is Steve Schultz. I'm Senior Vice President of Investor Relations at Compass Pathways. Today I'm joined by Kabir Nath, our Chief Executive Officer, Dr. Guy Goodwin, our 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.

We specifically disclaim any obligation to update or revise any forward-looking statements, even if our estimates or assumptions change. With that, I will now hand the call over to Kabir Nath. Thank you, Steve. Good day, everyone, and thank you for joining us. During this past quarter, Compass Pathways has continued to make excellent progress with our COMP360 phase III pivotal program in treatment-resistant depression, or TRD, with patients being treated in both trials. You may recall that on our Q4 conference call, we said that we expected the FDA to come back to us with comments on pivotal trial design amendments by March 20. We've now received comments for both the COMP005 and COMP006 trial designs. While I won't go into the details of our interactions with the FDA, I will say that the comments reflected an active and thoughtful dialogue. As you would expect with a drug development program that has Breakthrough designation, we will have ongoing engagement with the FDA more broadly over the whole course of the development program. The upshot is that we are continuing to execute both the COMP005 and COMP006 trials as described in our February conference call. Importantly, with no changes to the trial design. We also continue to expect top-line results for the six-week primary endpoint for COMP005 in summer of 2024 and for COMP006 in mid-2025. On the reimbursement front, the American Medical Association has accepted a current procedural terminology or CPT III code for psychedelic therapies. This was a very welcome development and the result of a collaboration between Compass Pathways and MAPS Public Benefit Corporation. Once effective, the CPT code will provide physicians and other qualified healthcare professionals with a means to track the work involved and ultimately seek reimbursement for delivering psychedelic therapies. Existing codes can provide coverage for the preparation and integration sessions, the new code will fill a gap and cover psychological support during administration. The full details of the code are expected to be released by the AMA in July this year, and the code will go into effect when it's published on January 1, 2024. Currently, clinicians are forced to use various different codes cobbled together to gain reimbursement for approved medicines that require observation or support during administration. This tracking code is a crucial step toward a single code that covers psychological support for therapies like COMP360, subject to FDA approval, and it's a critical step towards obtaining reimbursement. This helps enable broad and equitable access to psychedelic therapies. This ensures that FDA-approved psychedelic therapies could be integrated into healthcare systems, reimbursed by payers, and made available to the people who need them. Finally, we've continued our active engagement with biotech specialist investors. We've continued to communicate the depth and the progress of our programs and the strength of our value creation proposition in an area of significant unmet medical need. Since the beginning of this year, we've raised roughly $28 million from sales under our ATM facility, including a large block trade in April. With that, let me now hand the call over to Dr. Guy Goodwin to provide further clinical updates. Thank you, Kabir, and good day all. Let me begin with a review of our Compass -sponsored clinical program. In TRD, as you heard from Kabir, the phase III program is progressing as planned and we are actively treating patients in both trials. We are pleased with the rate of opening of clinical sites. This is a significant achievement as it's a complicated process to ensure that clinical sites are cleared to handle a Schedule I compound, are appropriately trained, and can recruit suitable patients. This level of infrastructure is unprecedented and one that we believe represents a significant competitive advantage for Compass, both in this and future programs. Once sites are past this stage, they are better able to concentrate on recruitment and patient management. I would therefore expect to see continued progress and acceleration on those fronts. Beyond treatment-resistant depression, our phase II studies in PTSD and anorexia nervosa continue to progress well and are on track. In the anorexia nervosa study, we told you on our last call that we had encountered some challenges in getting patients into and through the screening process. I'm pleased to report that we are now making excellent progress after amending and adjusting our procedures to enable recruitment more in line with our expectations. We look forward to updating you on future calls regarding expected timing. Looking beyond our sponsored trials to investigator-led studies, we continue to see encouraging data coming from these programs. In March, data on the use of COMP360 with psychological support in 12 patients with treatment-resistant body dysmorphic disorder, or BDD, were published in the Journal of Psychiatric Research. Individuals with BDD are preoccupied by aspects of their appearance that they misperceive as defective or ugly. In this study of a single 25 mg dose of COMP360, primary treatment effect was measured with the BDD-YBOCS score, which improved significantly over the 12 weeks of follow-up, with a large effect size and significant changes from baseline seen at week one and persisting through week 12, the duration of the study. At week 12, seven participants or 58% were considered responders. Secondary measures of BDD symptom severity, conviction of beliefs, depression, negative affect, psychological insight, and disability all similarly showed significant improvement. Tolerability and safety were evidenced by completion of all study visits by all participants and that no serious adverse events or occurrences of suicidal ideation were reported. The signals we see in this BDD study align with the hypothesis that difficult- to -treat disorders with preoccupying thoughts or fears represent potential target indications for COMP360 psilocybin therapy. This comes on the heel of another IIS we told you about in February that evaluated a single 25 mg dose of COMP360 psilocybin therapy in 14 patients with Type 2 bipolar depression, another condition for which treatment options are limited. This study produced very compelling data with 12 of 14 patients or 86% achieving remission at 12 weeks after administration without a resumption of antidepressant medication. It is this kind of information that these studies were designed to generate, understanding the potential of COMP360 in other indications with significant unmet need. These data sets also reinforce our confidence in our phase III program. I would expect to see additional interesting data from such studies as we move through this year. I will now hand the call to Mike for the financial overview. Thank you, Guy. I'll now recap our Q1 financial results. For the three months ended March 31, 2023, net loss was $24.2 million or $0.57 per share, including non-cash share-based compensation of $4.1 million compared to net loss of $21.2 million or $0.50 per share, including non-cash share-based compensation of $3.1 million for the three months ended March 31, 2022. I will now turn to the analysis of the three months ended March 31, 2023 compared to the prior quarter ended December 31, 2022. For the three months ended March 31, 2023, net loss was $24.2 million or $0.57 per share compared with a net loss of $39.0 million or $0.73 per share for the three months ended December 31, 2022. These results include non-cash share-based compensation of $4.1 million for the Q1 of 2023 and $3.3 million in the Q4 of 2022. Our Q1 financial results reflect our continued success in progressing our phase III trial in treatment-resistant depression. In line with our expectations, cash use in operations was $27.7 million in the middle of the guidance range we provided last quarter. Our R&D expenses were $19 million in the three months ended March 31, 2023, compared with $19.8 million in the three months ended December 31, 2022. The slight decrease was mainly caused by lower external development expenses due to the change in our phase III design. This decrease was partially offset by increased personnel costs. G&A expenses were $12.8 million in the three months ended March 31, 2023, compared with $12.4 million in the three months ended December 31, 2022. This increase was due to increased personnel and legal costs, partially offset by decreased facilities and other expenses. Our cash balance decreased by $26 million in the Q1 of 2023 due to using $27.7 million in operating cash, partially offset by $1.1 million provided by financing activities due primarily to the sale of shares under our ATM facility and a change of $0.7 million due to exchange rate impacts. The movement in operating cash is primarily driven by our net loss, partially reduced by non-cash charges. Regarding guidance, we expect the Q2 net cash used in operating activities to be between $22 million and $30 million, and the full year to be between $85 million and $110 million. The size of the Q2 range is due to the challenge in predicting the precise timing of cash raise to support our phase III program in its early stages. As the trial reaches steady state enrollment, we expect to offer a narrower quarterly and annual range. Compass continues to maintain a strong financial position with cash and cash equivalents of $117.1 million at March 31, 2023, compared with $143.2 million at December 31, 2022. In addition to our Q1 cash balance, in the Q2, we have received net proceeds of $26.9 million through the share sale of shares under our ATM facility, which has further strengthened our cash position and extended our runway. We view our strong balance sheet as an important strategic asset, which we 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. I'll now turn the call back to Kabir. Thank you, Mike. In closing, let me say that now as a phase III company, Compass Pathways leads the way in the development of psychedelic therapies. We believe these therapies represent the next generation of mental health therapeutic options. There's a significant and growing number of people across the world suffering from serious mental illness who are not helped by existing standards of care. We must act with urgency on their behalf. Most programs in this area of science today are unproven, early stage and risky. We've established a high bar for evidence regarding safety and efficacy. Many of those early stage clinical studies will likely fail to meet their primary endpoints, as we have seen with news from some other studies earlier this year. As Guy noted, we're progressing as expected in our phase III program in treatment-resistant depression. While we ultimately expect to leverage our extensive dataset to expand the development of COMP360 into a range of areas of unmet need, TRD is our first target indication and our clear focus. To this end, we continue to advance our commercial strategy on a number of fronts as we move through the phase III program towards an NDA submission with the FDA. The CPT III code, as discussed earlier, is a prime example of a successful step forward with our commercial approach and a clear indication that it can translate to significant value creation. As Mike noted, we continue to be in a solid financial position with a strong balance sheet to help us advance these promising therapies. We are making strong, meaningful progress in our work to develop and deliver new therapeutic solutions to patients who suffer from difficult- to -treat mental health conditions. Thank you again for your participation on today's call. We'll now turn to Q&A. I'll hand this back to the operator. As a reminder to ask a question, please press star one one on your telephone and wait for your name to be announced. To withdraw your question, just press star one one again. Please stand by while we compile the Q&A roster. One moment for our first question. Our first question comes line of Elemer Piros from EF Hutton. Your line is open. Yes, good morning. Congratulations on putting in the temporary CPT code, Kabir. Maybe one question about that is how precedented or not, having a code established 1 to 2 years before either MAPS or you are going to launch a psychedelic therapy. Maybe if you could contrast this to the situation with J&J's Spravato, which J&J may have not been as prepared as you may be. If you wouldn't mind comparing the treatment regimen with COMP360 to Spravato, especially considering that a patient would have to spend 8 x two hours in a clinic in the first month to receive that treatment. Just your take on J&J's first announcement, after, I think, four years of recording an annualized $500 million or so in revenue with that drug. Was wondering if you could provide a little comparison between the two? Thanks, Elmer, for the question. Just to check, you can hear us clearly? Yes, I can. Okay, great. Thank you. No, thank you for the question. I think, yes, you raise a couple of very important points here around the CPT code. I think first, let's understand that, as I said, there are existing codes that can, you know, account for preparation and integration, those fall within the normal range of psychotherapy sessions. We recognized a long time ago that in terms of a six to eight-hour administration session, or in the case of MAPS, multiple sessions of therapy associated with MDMA, that there were not the appropriate codes to cover that. It therefore became a priority for us working together to establish that. Recognize this is a CPT III code. This enables physicians and other HCPs to track the work that's involved, the activities that are required, and it's really a central precursor to converting that ultimately into a CPT I code that can be reimbursed. I think, you know, for Janssen, perhaps the recognition that the Spravato sessions under the REMS would require this monitoring period, which was different from anything else that was available at the time, was something that came a little later in the process. Again, we're grateful to have had the opportunity to learn from that. For the second part of your question, as you said, you know, esketamine does require multiple administrations in the first month and thereafter at regular intervals. That's not surprising given the relatively short duration of effect. Obviously, during our phase III, we're going to generate evidence around durability, around the impact of retreatment. That will give a sense also of when retreatment might be expected. Certainly we saw from the phase II-B a lasting effect for a significant number of patients even at 12 weeks. We have some modest data that suggests it can go longer than that. We would expect a much less frequent administration for COMP360 than you need to see for esketamine. We believe that that will also translate into a lower burden, not only for patients critically, but also for providers and treatment centers as well. Finally, yes, as you, as you mentioned, Janssen broke out for the first time Spravato sales this year, a few years into the launch. Let's recognize though the launch did come just ahead of the pandemic, which put all sorts of challenges into pharmaceutical drug launches. I think the fact that, you know, you saw over $100 million of sales in the U.S. in the Q1 with a strong growth trajectory is very encouraging for us in a couple of different ways. It shows first that despite some initial skepticism about the efficacy in clinical trials, physicians have become very used to working with esketamine and are actually seeing real world evidence of efficacy that perhaps, you know, the patient acceptance that's strong. I think critically it speaks to the fact that the infrastructure has developed significantly since the launch, not just in terms of, you know, interventional psychiatry centers, and we've talked in the past about some of those standalone centers, but also in the fact that other psychiatry practices, other academic and hospital settings, have become much more used to the fact that, you know, this is a treatment paradigm that's here to stay. We would expect much of that infrastructure to be relevant to us at Compass for psilocybin as well. Overall, I think we take strong encouragement from that and the fact that they've identified that as a growth driver. Yes. Thank you very much. At what point, I know it's too early in the launch, but at what point would you be able to project enrollment rates? For now you've reiterated the previous guidance for completion of both of those, both of the pivotal trials. Shall we expect that towards the end of this year or when you have a little more confidence on the trajectory? Yeah, no, it's a fair question, Elmer. I would just say definitely not yet, and I don't want to give a commitment to when we would do that. I mean, as I said, we have patients dosed in both trials. As Guy mentioned, you know, the fact that we are well on the way to building the trial infrastructure with more sites coming on board and so on is very encouraging. I don't want to promise a date of which we will actually give enrollment numbers or percentages enrolled. For now, given where we are, we are confident as we did in reiterating those timings for the primary endpoints. Thank you so much, Kabir. Thanks, Elmer. One moment for our next question. Our next question comes the line of Charles Duncan from Cantor. Your line is open. Hey, good morning, Kabir and team. Thanks for taking the question and congrats on the progress. I did have a question regarding the ongoing phase IIIs. Maybe you're not gonna be able to answer them, but I'm wondering if you could provide more color on the FDA interactions, you said they're active, thoughtful dialogue, but I guess I'm assuming no modification in the primary or secondary endpoints. Perhaps if Guy could speak to the pacing of the trial. Great to see that you've made some progress in terms of patient enrollment. I'm wondering if the biggest, you know, call it rate limiter for this trial is site opening or is it patient access and availability of, you know, appropriate patients? Thanks. Thanks, Charles, and I'll actually ask Guy to take both of those parts if that's okay? Yeah. As you know, Charles, there's no change in primary outcomes, there's no fundamental change in the design of the studies as a result of our to and fro with the agency. We're well on track as far as we're concerned with recruitment at the moment. You ask an interesting question because it falls into different phases of the studies. At the beginning, the limiting step is simply site initiation. That takes time. It takes things to happen which are quite beyond anyone's control. Well, beyond the control of us and of the investigators, which are things like EMA licenses. DEA license funding. We are obviously plotting and we have modeled the rate at which patients will be recruited. I would simply say that as far as our simulations of the future go and as far as we can be confident in the way we've achieved opening so far, we're looking very good. Obviously we expect that once all the sites are open, then there will be different considerations around what limits recruitment. We anticipate the demand for entry into the studies to be unusually positive for most compared to most depression studies. We know from feedback we have had from the sites, that's certainly true in some centers. We look forward to seeing the results of that, and we'll be tracking it very carefully. Of course, it's the key metric for us over the next 12 months to see that rise in recruitment curve. We're happy that we'll be able to do that and give you some indication of our happiness with it. We're gonna be careful about numbers because they can be misleading and they can be misunderstood. Yeah, absolutely fair on that. Appreciate it. Regarding anorexia nervosa, quite intrigued with that. Happy to hear that it's kind of back on track. Can you provide any additional information on the actual amended procedures or how they were amended or what is perhaps changed a vector on that trial versus last quarter? They were quite minor amendments to the protocol. I mean, unfortunately, that takes time. They were really to do with the visit burden on patients and just, you know, the preparedness of patients to participate in the study. You'll appreciate that randomized clinical trials are not like ordinary practice. They place unusual demands on the subjects who participate. I think that the need for in-person visits in particular was something that was too demanding in the initial stages, and we felt no reason for, not changing because it didn't materially affect how the study would run or the results. It's been a simplification of the trial design, if not a fundamental change in the actual objectives or the questions that it will answer. Okay. That's helpful. Last question for Mike. Quickly on the ATM, that was noted a large block trade. You may not be able to fully answer this, but I'm wondering if you could characterize the investor. Obviously not a certain identity, but maybe an investing type or whether or not they had previously held a position. Any additional information that you could provide there. Thanks. Because the investment came in through the ATM, I am a little bit limited on the information that I can provide. I would point out that if you go back and look at trading volumes, earlier in the quarter, it's pretty clear when that happened and the size of it. I can characterize the investor. You know, we've spoken on prior calls that we've been working pretty intensively to bring biotech specialists, sophisticated investors into the register. You know, not only to support us with our current financing needs, but, you know, investors who are gonna understand the fact that we're going to be coming back, you know, additionally in the future as we get closer to commercialization and as we build for a successful launch. Those conversations continue, and we continue to make progress. I'd say that, you know, this investor would fall into that realm of the investing universe that we've been working closely with. That makes sense. Sequentially, funding the company I've seen with other neuro innovators. Should work here too. Thanks for taking my questions. Sure. Thanks, Charles. One moment for our next question. Our next question from the line of Frank Brisebois from Oppenheimer. Your line is open. Hi. Thanks for taking the question. Just in terms of the reimbursement, can you just, you know, we in a prior question, Spravato was brought up quite a bit. I'm just wondering, Spravato just, you know, for those that might not be aware, what coding do they use? Is it, you know, this G-code that is that like, how different is that from a CPT I? And just maybe understanding, you know, the, you know, for investors here, the difference here between the G-code, CPT I, and CPT III, and then maybe, you know, what kind of additional color could we be expecting in July here? Thank you. Yeah, no. Thank you, Frank. It's a great question. The first thing I will say is, since these codes are only going to be published in July, we're actually not going to talk in very much detail about what we expect to see in them or what they will actually cover until after that, because, you know, the AMA would not like us to do so. I think, you know, what I would focus on is what we have done here, which is acknowledging that for psilocybin specifically, this six to eight-hour administration is a unique model of psychological support for which nothing existed. You know, the idea of stringing together multiple codes to do that would clearly be unappealing to providers, not necessarily feasible, and also would not give any consistency. That's the reason that we actually focused therefore on obtaining this code. I think, you know, what Janssen is doing is using a variety of different codes. It is a different model of support, as you're aware. It is post-administration monitoring as opposed to support during administration. They have been able to use a number of different codes. I think more we would like to hold till after the summer when we can talk more about the CPT code and then get into some of the different mechanisms for payment. Obviously there are some areas where we're seeing bundled payment across drug and provision of services, some areas where we're seeing that separated. I think we're very happy to get into more discussion around that once the details of the code are out and published. Thank you. One moment for next question. Our next question comes the line of Josh Schimmer from Evercore ISI. Your line is open. Hey, sir. I'm taking the question. Before just coming back to the to the CPT codes. If they go into effect January 1, that means that is when the resource consumption analysis will begin. Over what time does that occur, and when do final codes and reimbursement likely go into place? If it's gonna be done for both MAPS and Compass, how do the codes reconcile differences between the resource consumption that may exist between the two products? Thank you. Thanks, Josh, for the question. On the latter part, you know, once we see details of the code, I think that will make it clear some of the answers to the second part of the question. For the first part, there is no fixed timeline from which a CPT III code grows up, shall we say, to become a CPT I code. What happens is that from January 1, it will be available to be used for tracking activities. What's important is that there is adoption, that there is good experience, but also that the data that we continue to generate through the trials, the data that MAPS may start to generate in the real world supports strong evidence of efficacy and so on. Again, there is a process of building that body of evidence. As you say, starting to actually construct the value elements of it, but there is no fixed timeframe for this becoming reimbursable. Obviously, by doing this well in advance of when we may be able to launch, it is our hope and expectation that we will be able to have something that is reimbursable at or very close to launch, but that's gonna depend on continuing efforts by us, by MAPS, and potentially others from January of next year. Okay, got it. Now that you've seen an uptick in enrollment in the anorexia trial, when do you expect to be in a position to report data? I think to be honest, that we, you know, we base this on a recruitment curve. We're still at the stage of developing that curve to see where it will saturate, where we'll get to the required numbers. It would be premature to give a date just at this minute. You know, we're confident that we're on track to complete the study and the exact timing we will release when we're more confident about it. Okay, thank you. Thanks, Josh. One moment for our next question. Our next question comes from the line of Patrick Trucchio from H.C. Wainwright. Your line is open. Thanks. Good morning. Just a quick follow-up on the potential commercialization. As we look ahead to the potential commercialization of COMP360, I'm wondering if you could frame for us what a potential REMS program could entail and if it would be similar to Spravato's or would there be some important differences we should be aware of? How could this in some way help streamline the launch of COMP360? Thanks, Patrick. I mean, I guess, you know, it's a little premature to speculate on the shape of the REMS. You know, because also to a large extent, that will follow the label and what's in the label in terms of what's in the REMS. Yeah, I think, I think we can be clear that we do expect a REMS with, as you'd expect, the key element being the ETASU, the elements to assure safe use. Those are clearly going to require, I would expect, you know, essentially distribution through specialist pharmacies to treatment centers for a given patient with the indication and so on clear. It will require physician certification, you know, patient certification and so on. Beyond that, in terms of the scope and, you know, what we may end up negotiating with the FDA around the actual elements, honestly, I think it's premature. Yeah. That's really helpful. I'm just wondering if you can talk about the level of interest or acceptance in psychedelic therapy, specifically among the neuropsyche opinion leaders and clinical trial investigators. How have these views changed, particularly as we had more data published, including from the COMP360 phase II-B trial? How do you view this evolution, you know, as progressing as we approach, you know, the phase III readout next year for COMP360? Thanks, Patrick. I think it's, within the academic sites, there's a certain, there's a mixture. You know, some people still think that the commercialization will be difficult. In a sense, it's not university sites' opinion that's really gonna matter in that. It's really to do with the kind of relationships we build with more commercial providers. I think that the impressions I get certainly are there's great enthusiasm for the idea, and there's really very little pushback on the, our interpretation of the data. The enthusiasts for this area think it's gonna be great and are really positive about it. We have to recognize that many of the sites who are doing the trials are not necessarily all going to be commercially active. I think overall, the feeling is that there's a lot of enthusiasm within the profession for this approach, and there's a lot of acceptance that there needs to be changes to allow it to happen. I think that's very important. I think the final thing is that this is gonna be an opportunity for patients who have not currently receiving adequate treatment actually to get it. Because I think there's gonna be a move to not leave people in primary care inadequately treated, not receiving the kind of additional treatments that sometimes work. This will provide an attraction, I think, for getting those sort of patients who are currently not being treated into treatment. I think a lot of psychiatrists recognize that, and we'll certainly be as we go forward, we'll be driving along with the key opinion leaders, that particular message. That this is an area that is not only failure of treatment but in really not offering adequate treatment to people. Yeah. Yeah. I would just add, we're starting to engage with regional health systems. Not necessarily household names, not the big ones you've heard of, but regional health systems that are seeing significant numbers of patients that are already offering TMS, Spravato, in some cases ECT. The level of excitement there and interest is extremely high. They are very interested to see how they can add this as another option for certain patients. Both existing patients who are not benefiting from current treatments, but also, as Guy said, extending it to other patients. Again, early days. Obviously, we don't wanna go too fast with that. You know, we are, as I say, starting to engage with a number of those and getting a lot of very positive feedback. Terrific. Thank you so much. One moment for next question. Next question comes from the line of Ritu Baral from Cowen. Your line is open. Good morning. Thanks for taking the question. I apologize for my voice this morning. About the CPT code, can you clarify when the information gathering for resource utilization exactly begins? Or Kabir, I think that you and I have talked about this. It, and I believe it covers the administration session. I'm wondering, is there possibility that it might capture the prep session? Would you want to create a different CPT code for that prep session, or do you think and the consolidation session. Do you think that existing codes would cover prep and consolidation? I'm gonna go follow up. Thank you. Thanks, Ritu. So yes. you know, our belief is that existing codes can follow, can support preparation and integration. The need, the gap was code or codes that could cover the administration. I think it's also important to acknowledge, obviously in a trial setting, it is the same therapist for preparation and administration and integration. In a real-world commercial setting, you could well see that a patient may have an existing relationship with a therapist who would actually be involved in the preparation and integration sessions, and the support required during the administration would come from a different provider. That's a model that we may well see emerge. In that context as well, our focus really was on the novel piece, the gap that existed for this extended administration. It's just, this CPT code will just be the administration session. Well- From the start. Again, let's wait for July and see the details of it. It's actually three codes, not just one. You know, we can't go into any more detail now, but let's wait for that to see it. In terms of when it can start, as we said, it's the January 1, 2024. That's the point from which people can start to use this code to track activities, to track what's actually happening during these sessions. Understood. Just moving to TRD. You mentioned changes to promote enrollment because of challenges getting patients through screening. Can you describe some of those changes to the protocol, and do you believe that, excuse me, do you believe those changes will result in any material changes in the patient population when you originally projected? Thanks for taking the question. Thanks, Ritu. I don't think it'll change in patient population. This is a fairly defined condition as I'm sure you know. I mean, the issues really were around patient burden and participation in the study. I guess we had assumed that the patients would be more tolerant of that, leading from our experience with TRD. I think quite simply, many of the patients with anorexia nervosa are more ambivalent about treatment, so that additional burden, I think, may have served as a barrier. By burden, I simply mean, you know, having to turn up for multiple visits in person, which were not strictly necessary, but in a sense were simply put down because that is the way we had previously done studies. There is a tendency to trust in face-to-face assessments more than remote ones. There's no real reason to do that when one's not dealing with the primary outcomes, and therefore we modified the protocol to allow more remote assessment. We don't think that reduces the quality of the information we will get materially. It doesn't change the outcomes. The key measurements of outcome will remain in person, and therefore will be the same as originally planned. The changes are relatively modest, but they may make a surprising difference, and we will obviously hope that they do and keep you updated on when they do. Thanks for taking the question. Pleasure. One moment for our next question. Our next question will come from the line of Neena Bitritto-Garg from Citi. Your line is open. Hey, guys. Thanks for taking my question. I remember last time on the, on the last earnings call, you mentioned addition of part B and part C to both phase III TRD studies. I was just wondering if you could share at this point what the retreatment criteria are in those two parts. I know part B I think has optional retreatment, and then part three I believe is based on a relapse. Can you just provide us with the actual criteria for both of those? That'd be great. Yeah. I mean, the criteria for retreatment are essentially, that patients, have a MADRS above a certain threshold, and that threshold will be a threshold of 20 on the total score. Okay. It's the same in both part B and part C? It's the same in both parts, yeah. Okay. That's helpful. Awesome. Thank you. Thanks, Nina. One moment for our next question. Our next question comes from the line of Suman Kulkarni from Canaccord. Your line is open. Morning or afternoon for some of you. Thanks for taking my questions. In the past, you've said that there would be no interim analysis for COMP005. Is that still the case? If there is no interim analysis, do you plan to provide any efficacy updates on a blinded basis? When could one expect those relative to the top-line data in summer of 2024? Did I hear that? Yes. Suman, I think your question was, do we plan an interim analysis? The answer remains no. No, we should not expect to know anything before summer of 2024. Got it. Could you specifically compare the in-person support services during psychedelic therapy that may be needed for COMP360 versus MAPS, which is specifically characterized as MDMA-assisted therapies? Obviously, these are different treatments and indications, but I'm trying to get a relative sense of the reimbursement burden. Let me start, and Guy may jump in. I mean, a psilocybin session, as we know, consists of, you know, for a patient, there is preparation. There is the actual administration session itself, which is six to eight hours, and there is integration. As you know, in phase II-B, we studied one dose. In the phase III, we have both the two-dose study in the core part of the protocol as well as the single dose. As just reference, we do have an option for retreatment on relapse or failure to remit, in part B and then again in part C. You know. That is kind of the burden for us from a psilocybin perspective. The MDMA protocol from recollection is at 12 therapy sessions, including three doses of MDMA, I think. That's correct. Yeah. I think it's also fair to say the interactions that take place on the therapy days with the drug are quite intense. The drug is sometimes described as producing greater empathy and therefore more communication with between people. That contrasts with psilocybin, where on the day of administration at the doses we are using, 25 mg, the patients are essentially inwardly guided. They're not interacting with the therapist. In fact, the therapists are instructed not to interact with the patients other than to help them to, in a sense, remain focused on their internal journey, is the word that they usually use. You know, there's a great difference in the way we should be thinking about the role of psychotherapy. Psychotherapy is a key part of the MDMA treatment. It is not a key part of the psilocybin treatment, and that's why we have used the term psychological support, where the emphasis is really on safety and safeguarding, and it is not on essentially a treatment of a psychotherapeutic kind. Understood. Once the CPT III code goes live in 2024, is there any potential for approved but off-label products ability to utilize this code for therapy sessions? It's a good question. I guess at the discretion of the provider, yes. I'm actually not entirely sure. Thank you. Thank you. With no further questions in the queue, I'd like to turn the call back over to management for any closing remarks. Thank you very much. Once again, thank you everyone for your participation, and thank you for the questions as well. Just a reminder, we are making excellent progress on our phase III trials for treatment-resistant depression, as well as continuing to build the body of evidence for COMP360 more generally. We're excited obviously about the CPT III code. We're excited about the validation externally that you see from Spravato as well in terms of momentum, and we believe we're also making strong strides towards demonstrating a commercial value proposition for COMP360. Thanks, everyone. Have a good rest of the day. This concludes today's conference call. Thank you for participating. You may now disconnect. Everyone, have a good day.
