Thank you, Tim, as always. And good afternoon to everyone and welcome to Relmada third quarter 2023 conference call. We have achieved some important clinical milestone recently in the ongoing Phase 3 program for REL-1017 in major depressive disorder, or MDD, as well as in our promising preclinical novel psilocybin program that I will briefly cover today. Following this, Maged will review the third quarter financial results and then we will take your questions. Let's begin with an update on the Phase 3 program for REL-1017, which continues to proceed as planned. As a reminder, Relmada is focused on developing REL-1017 as an adjunctive treatment for MDD. As previously communicated, we have made critical changes to RELIANCE II, the ongoing Study 302, a Phase 3, two-arm, placebo controlled, pivotal study evaluating REL-1017 25 milligram for adjunctive MDD. The amended Study 302 protocol has been implemented across all our clinical sites. Enrollment is progressing as we leverage our close relationship with the study sites and the number of ongoing initiatives to drive prior awareness with prospective patients. As a reminder, we are planning to enroll approximately 300 patients and continue to expect that RELIANCE II will be completed in the first half of 2024, most likely toward the end of the first half, so around mid-year. In the second Phase 3 trial of REL-1017 named Relight, or Study 3042, we began dosing patients during the third quarter. Relight also has a planned enrollment of approximately 300 patients. Completion of enrollment in this trial continues to be anticipated in the second half of 2024. To reiterate what we have said previously, like RELIANCE II, Relight is a randomized, double-blind, placebo-controlled four-week trial evaluating the efficacy and safety of REL-1017 as an adjunctive treatment for MDD in patient experiencing inadequate response to ongoing background antidepressant treatment. The primary end point of both studies is the same, the change in the MADRS total score from baseline to day 28 for REL-1017 as compared to placebo. Also, during the third quarter, we announced efficacy and safety results from the open label, one year safety study for REL-1017, Study 310. These long term safety exposure data are required for the purpose of the NDA filing. More specifically, in September, we shared efficacy results for the 204 de novo or new to treatment patients and safety results for all 627 study subjects. Study REL-1017 310 was a long term, open label – noncomparative open label, registrational Phase 3 trial designed to evaluate the efficacy and safety of REL-1017 administered one daily in patient with MDD for up to one year. I will now reiterate some of the previously communicated results in the de novo patients. Rapid and sustained improvement in MADRS score were observed with REL-1017 in the de novo patient and the entire study population. As the de novo patient reflect the more reliable picture of the real world condition, I will highlight the de novo patient results. The mean MADRS score, total score was 33.8 at baseline. Treatment with REL-1017 in this patient resulted in meaningful improvement from baseline in the MADRS total score of 16.8 points at month one, 19.9 points at month three and six and 22.5 points at month 12. High rates of clinical response, both rapid and sustained, were seen in de novo patients. When treated with REL-1017 in the MADRS total score at day 7, 26.6 patient of the de novo patient achieved the clinical response that is defined as the greater than or equal to a 50% improvement in the MADRS score, which increased to 51% by month one and 77.2% by month 12. Virtual absence of depressive symptoms or clinical remission was achieved by 12.1% of the de novo patients at day 7, which increased to 30.1% at month 1 and then again 54.4% at month 12. Clinical remission is defined as the MADRS total score of less than or equal to 10. In summary, patients treated daily with REL-1017 for up to one year experience a rapid, clinically meaningful and sustained improvement in depression symptoms and associated functional impairment. Importantly, the overall MADRS change and response and remission results in Study REL-1017 310 for the de novo patient and the full analysis that were consistent in both groups. For all the REL-1017 310 subjects, REL-1017 was well tolerated with long term dosing showing low rates of adverse events and discontinuation due to adverse events. No new safety signals were detected. Moving now to our promising preclinical novel modified release psilocybin program. At next week or this weekend AASLD meeting, the new data will be presented in a poster presentation. The data demonstrate the beneficial effect of non-psychedelic low dose psilocybin on multiple metabolic parameters in a rodent model of metabolic dysfunction associated steatotic liver disease, or MASLD. As a reminder, there are not currently approved drugs for MASLD. And these initial preclinical results support the therapeutic potential of non-psychedelic, low dose psilocybin. Based on this data, non-psychedelic low dose psilocybin could improve lipid and glucose levels, with potential for fewer side effects over other investigative treatment approaches, such as the GLP-1s. We intend to initiate a single ascending dose Phase 1 trial in obese patients with steatotic liver disease in early 2024 to define the pharmacokinetics, safety and tolerability profile of our modified release psilocybin formulation in this population, followed by a Phase 2a trial in the same patient population to establish clinical proof of concept. Moving on, Maged will provide a detailed review of our financials. But I would like to emphasize that Relmada remains sufficiently funded to fully execute our plans to reach data readouts for both REL-1017 Phase 3 trials, RELIANCE II and RELIGHT. I will now turn the call over to Maged to review our second quarter financial results. Maged?

Thank you, Sergio. Today, we issued a press release announcing our business and financial results for the three and nine months ended September 30, 2023, which I will now review. For the third quarter ended September 30, 2023, total research and development expense was approximately $10.5 million as compared to $30.5 million for the comparable period of 2022, a decrease of approximately $20 million. The decrease was primarily associated with the completion of RELIANCE I (that's Study 301) and RELIANCE III (Study 303) in late 2022. The non-cash charge related stock-based compensation totaled $1.7 million in the most recently completed third quarter. Total general and administrative expense for the third quarter ended September 30, 2023 was approximately $12.2 million as compared to $8.2 million for the comparable period of 2022, an increase of approximately $4 million. The increase was primarily driven by an increase in stock-based compensation. This non-cash charge totaled $9.6 million in the most recently completed third quarter. Net cash used in operating activities for the three months ended September 30, 2023 totaled $11.6 million compared to $26.9 million for the three months ended September 30 2022. For the third quarter ended September 30, 2023, the net loss was $22 million or $0.73 per basic and diluted share compared with a net loss of $39.4 million or $1.31 per basic and diluted share in the comparable period of 2022. Turning to the results for the nine months ended September 30, 2023. Total research and development expense was approximately $40.1 million as compared to $86.5 million for the comparable period of 2022, a decrease of approximately $46.4 million. Again, the decrease was primarily associated with the completion of RELIANCE I (Study 301) and RELIANCE III (Study 303) in late 2022. The non-cash charge related to stock-based compensation totaled $5.5 million in the most recently completed nine-month period. For the nine months ended September 30, 2023, total general and administrative expense was approximately $36.8 million as compared to $36.1 million for the comparable period of 2022, an increase of approximately $700,000. The increase was primarily driven by an increase in stock-based compensation. This non-cash charge totaled $28.5 million in the most recently completed nine month period. Net cash used in operating activities for the nine months ended September 30, 2023 totaled $41.4 million compared to $67.9 million for the nine months ended September 30, 2022. For the nine months ended September 30, 2023, net loss was approximately $73.6 million or $2.45 per basic and diluted share compared to a net loss of $119.1 million or $4.04 per basic and diluted share in the comparable period of 2022. As of September 30, 2023, we had cash, cash equivalents and short-term investments of approximately $106.3 million compared to approximately $148.3 million as of December 31, 2022. Again, cash used in operations for the third quarter was $11.6 million. Based on our clinical development plan, our current cash position provides us with ample runway through the end of 2024. Of note, this time period, as Sergio mentioned, includes data readouts from both Phase 3 trials – RELIANCE II (that's Study 302) and RELIGHT (that's Study 304) as well as the initiation of our planned Phase 1 trial for our modified release psilocybin formulation. And I'll turn the call over now to the operator.

[Operator Instructions]. Your first question comes from Marc Goodman, Leerink Partners.

This is Basma on for Marc. Congratulations on the quarter. I have a question regarding the RELIANCE OLS study. Was this study conducted in the same sites as RELIANCE I and RELIANCE III? And I also have a question about the RELIANCE I and RELIANCE III regarding the patient characteristics. Can you remind us again about the average age of the participants after you looked at the data, after you unblinded the data? And have you noticed any correlation between the inaccurate diagnosis of MTP and the age of the participants?

I do believe that Cedric, our Chief Medical Officer, is the most appropriate to address them. Cedric?

Yes, as is very common, when you have controlled trials, you also have an open label extension trial that's offered. So, therefore, yes, the sites that were part of RELIANCE I and RELIANCE III also had the opportunity to be part of the open label study and contribute subjects to that long term study. There was a question then about the average age. And these studies are run in adults 18 to 65 years of age. And of course, you that major depressive disorder is represented as a 2 to 1 ratio in females than males. We haven't looked at age breakdown. There's lots of interesting analysis that we want to do, but can't comment on a correlation or outcomes by age. But the average age was probably in the area of the 40s or 50s.

Your next question comes from Uy Ear, Mizuho.

This is Charles on for Uy. I guess I kind of had a follow-up question to that, if there was any other read-throughs from the open label de novo patients to the Phase 3 studies. And then also if you saw a difference between the adjunctive and mono therapy patients from that open label.

Sergio here. Let me try to give you a little bit more like top down and then Cedric can go more in detail. And so, the long term safety studies, 12 months, and we looked at the MADRS improvement data. And the conclusion are simple, but significant and material because these represent real world experience. So, what we have seen is that there is a rapid effect and there is a clear effect. 70 plus percent of the patient responded after 12 months and the – they sustained. So, there is no loss of efficacy over time. And the safety is confirmed that the drug is extremely safely and well tolerated. So these are really the key learning in a real world experience. The question to, there is a difference in the adjunctive and monotherapy, in the 12-month studies, not really, like very significant to make a difference. It's a mix. It would be unfair to separate monotherapy from adjunctive because we don't know, in 12 months, what people do. Somebody take medication, they stop them. Somebody doesn't take them. So it would not be a reliable information. Though, we look at the de novo and the overall population that come from the two Phase 3 studies. It's over 500, 600 patients. There is really no difference that would be remarkable. Let's put it this way, there is no subset of patients that would spike either way that the drug didn't work or they work extremely well. It's pretty consistent, and that make us comfortable because this is a real world experience. Cedric, do you want to add anything to my remarks?

I think you said it all. Just to confirm what you said that there's this consistent improvement trajectory with rapid onset. The de novo are the ideal group to look at when you're looking at efficacy in the open label. Because that study isn't as well controlled as our placebo controlled trials on who gets in. So there's a lot of subjects – and you don't – and a lot of common medications that they're on. So it's quite a mixed bag. But one thing is consistently observed is that whatever the treatment setting, patients got better quickly, with really high response and remission rates in the open label and consistent trajectory as we've also seen in the controlled trials.

Your next question comes from Andrew Tsai, Jeffries.

This is Dina on for Andrew. We just had a couple of quick questions. What are each of your two Phase 3 studies sort of powered to show in terms of MADRS separation versus placebo? And a question for Cedric. Operationally speaking, how can you say with high confidence the study integrity for the two Phase 3 studies in 1017 are similar to how Axsome successful studies were run? Are you seeing a lot of similarities between those two programs and if you could just elaborate on?

Maybe Cedric should answer that. I just would like to try to answer your last question on the comparison with Axsome. Cedric runs both the trials, running our trial and run Axsome trial. But these are very, very, very different drugs. So I don't know how much would be reliable to compare the two programs. And, Cedric, do you want to try to answer?

I think that anybody who's in the drug development space, particularly in major depressive disorder, very much tries to run as high quality a program as possible. And that really comes down to three things, the protocol, the site selection, and subject selection. And so, it doesn't matter which sponsor you work for, you want to have a very tight, efficient protocol that aims to reduce placebo response. And then you want to work with the best sites that are conducting MDD trials. And of course, those of us who work in clinical research for depression know that there are always the same sites known to the sponsor. So, you would expect that there would be knowledge and familiarity because these sites are the best in major depressive disorder. And then, you just have to very carefully have an eligibility process that makes sure that you're getting the right patient with confirmed diagnosis of MDD and you're avoiding professional patients. And you're doing everything from a subject selection process as well that might minimize recruiting or enrolling patients – or subjects, I should say, who might be prone to having a high placebo response. So you do that across the program, and I have to say that I'm very pleased with how rigorous our eligibility process is in letting subjects into the trial. And the question on the statistical powering, we haven't actually revealed that yet. So, it would be reasonable to – if you take the Phase 2 data and if you were to consider 301 or 303 where placebo was controlled to about 10 or 11 points improvement on the MADRS, you could probably figure out how we're powering it because we are targeting approximately 300 subjects, as Sergio mentioned at the beginning. So I hope that helps a little bit there with an answer to your question.

Just one quick point. According to the KOLs and the history literature, a difference in MADRS score versus placebos, 2, 2.5 points is considered clinically meaningful and enough for approval. So, you may imagine that we will file the statistical plan according to these parameters. So, the statistic will be set up to detect a MADRS difference from placebo that is clinically meaningful and good enough for approval. Hope I answered appropriately your question.

[Operator Instructions]. Your next question comes from Yatin Suneja, Guggenheim.

This is Salma [ph] for Yatin. So I have a few questions on the psilocybin program. I just wanted to ask you if you have already filed the IND for the Phase 1 trial and how many doses are you planning to use there. Are any of these doses expected to trigger a psychedelic experience.

I answer – Sergio here – the first part of the request. And then if you don't mind to repeat the second one because I couldn't hear you very well. No, we haven't filed the IND. We are on the process to prepare the IND and I do believe will be filed relatively soon. But we are planning to start the Phase 1 single dose ascending in Q1 next year. So let's say, two, three months from now. Can you please repeat the second part?

I was just asking how many doses you are planning to test there. And if any of these dose is expected to trigger a psychedelic experience?

How many doses? No, we haven't finalized the exact dose regimen. We'll discuss in the IND. But what I can share with you is what will be the dose limiting toxicity. And it is not real toxicity because we know that psilocybin is well tolerated from the literature and the history and from other programs that are ongoing that are using 20 mg, 25 mg in a single dose. And we will use one-tenth of that. So it's a fair assumption that the dose we'll be using will not be toxic or not well tolerated in general terms. But the dose limiting toxicity that we are trying to determine is when you start to have psycho symptoms, if I put it in this way, when you start to feel that the drug is affecting your psych. So, we are developing a low dose extended release that is non-psychedelic. So the dose limiting toxicity will be the psychedelic effect. We don't know exactly what the dose is, but we assume that it will be below 3 mg, 4 mg daily.

Thank you. There are no further questions at this time. Please proceed.

Well, thank you. Look, in summary, we remain confident that we do have an approvable drug in REL-1017, and we are excited about the potential of the novel psilocybin in derivative problems. We look forward to reporting the progress with our pipeline in the months ahead. And I do remain grateful to the Relmada team for their continued hard work and dedication to executing on our mission. I would like to extend my sincere thanks to the patients and clinical partners involved in the REL-1017 trials for their participation in the advancement of this promising investigational medicine to development. Thanks a lot to everyone and we'll reconnect soon.
