Thank you, Tim, as always, and good afternoon to everyone. I'm pleased to welcome you to the Relmada fourth quarter and full year 2022 conference call. We are coming off from a challenging 2022, but we have learned a great deal from our completed studies and believe that these learnings, better enable us to realize the potential of REL-1017 for the treatment of MDD. Following the availability of topline results for REL-1017 in RELIANCE I or Study 301 in December 2022. We have spent the last three months, analyzing these data and considering the appropriate next steps. As a reminder, RELIANCE I or Study 301 and RELIANCE II or Study 302 are two Phase 3 sister two-arm, placebo-controlled, pivotal studies evaluating REL-1017 at 25 milligrams is an adjunctive treatment for MDD. Study 302 is ongoing. We are confident that we have identified the key issues that led to the Phase 3 data in Study 301 differing from the positive results seen in Phase 2. As such, we intend to focus on REL-1017 as an adjunctive treatment based on the data generated to-date and market potential and will initiate one new trial Study 304 and implement critical changes to the ongoing study 302. Our Study 302 protocol amendment has been finalized and is ready to be implemented immediately. And our new Study 304's protocol has been drafted and will be ready to initiate by mid-2023. I would like to emphasize that broadly, we have learned that the two most important drivers for a successful depression trial are recruiting the appropriate patients with MDD and controlling the placebo response. It is proposed that REL-1017 unlike conventional oral antidepressant except it's antidepressant effect by inhibiting and correcting the consequences of hyperactive glutamatergic pathways. It does not affect mood by altering neurotransmitter levels and…

Thank you, Sergio and first slide, please. To begin, you will recall that in study 301, REL-1017 did not meet statistical significance on the primary endpoint. Treatment with, REL-1017 did result in a 15.1 points change from baseline on the MADRS total score but placebo-treated patients experienced an improvement of 12.9 points, representing a high placebo response. It is widely accepted by experts that it's the placebo change on the MADRS, total score exceeds about 10 points you have failed to adequately control placebo response. Despite this high placebo response, the placebo adjusted delta favored REL-1017, and was 2.3 points a clinically meaningful difference meta-analysis show that the average drug placebo difference that has resulted in the approval of oral anti-depressants over the past decades has been approximately 2 points. Next slide please. We did see in study 301, that it's statistically significantly greater proportion of patients treated with REL-1017 experienced therapeutic response defined as a 50% or more improvement in the MADRS, total score from baseline at day 28, 40% with REL-1017 treatment versus 27% for placebo with a p-value of 0.044. Next slide please. Now let's take a look at the per protocol analysis of study 301. It is important to note, that this was a pre-specified analysis per protocol refers to the population of patients who were treated to day 28 and who did not have any major protocol deviations. This pre-specified analysis only resulted in the exclusion of 29 patients and demonstrated a 3.1 placebo adjusted difference in favor of REL-1017 at day 28, with a p-value of 0.051, approaching statistical significance. The total N in this pre-specified analysis was a robust 198 patients versus the 227 patients in the intent to treat primary analysis. From the primary and pre-specified analysis, including response rates and per…

Thank you Cedric. Today, we issued a press release announcing our business and financial results for the three and 12 months ended December 31, 2022, which I will now review. For the fourth quarter ended December 31, 2022, total research and development expense was approximately $26.9 million as compared to $25.3 million for the comparable period of 2021. The increase was primarily related to an increase in stock based compensation. This non-cash charge totaled $2.2 million in the most recently-completed fourth quarter. Total general and administrative expense for the fourth quarter ended December 31, 2022 was approximately $11.8 million as compared to $8.9 million for the comparable period of 2021, an increase of approximately $2.9 million. The increase was primarily driven by an increase in stock based compensation. This non-cash charge totaled $9.4 million in the most recently completed fourth quarter. For the fourth quarter ended December 31, 2022, the net loss was $37.9 million or $1.28 per basic and diluted share. Compared with a net loss of $34.4 million or $1.80 per basic and diluted share in the comparable period of 2021. Turning to the results for the full year December 31, 2022. Total research and development expense was approximately $113.3 million as compared to $90.6 million for the comparable period in 2021. The increase was primarily related to an increase in costs associated with the execution of a broader clinical program for REL-1017. For the year ended December 31, 2022, total general and administrative expense was approximately $47.9 million as compared to $35.1 million for the comparable period of 2021. The increase was primarily driven by an increase in stock based compensation. For the year ended December 31, 2022, the net loss was approximately $157 million or $5.30 per basic and diluted share. Compared with a net loss of $125.8 million or $7.16 per basic and diluted share in the comparable period of 2021. As of December 31, 2022, we had cash, cash equivalents and short-term investments of approximately $148.3 million. Compared to cash, cash equivalents and short-term investments of approximately. $211.9 million as of December 31, 2021. Based on the updated clinical development plan, Sergio and Cedric shared earlier, our current cash position provides us with ample runway of approximately two years of cash. I'll now turn the call over to Sergio. Sergio?

Thank you, Maged and Thank you, Cedric. So in summary, we are confident that we have an approvable drug and need to focus on clinical trial execution. Based on the results of Study 301, we now know how to identify the most reliable sites, the most suitable patients and greatly improve our study protocols. Also importantly all other preclinical, clinical and CMC pieces are in-place for a successful NDA filing for REL-1017. Additionally, as stated earlier, we are sufficiently funded to fully execute on our plans for REL-1017 development as we ended 2022 with approximately $148 million in cash, cash equivalents and short-term investments. We look-forward to reporting on progress with Study 302 and 304 through the year. And now, we will ask the operator to please open up the call for questions. Operator?

[Operator Instructions] Our first question comes from Uy Ear with Mizuho Health. Please proceed with your question.

Hi, guys. Thanks for taking my questions. So, I guess my first question is, I think you indicated that for 302 the protocol is pretty much finalized and you already started immediately. So, have you started re-enrolling and re-dosing patients in 302 and Secondly, For 304, do you need the FDA blessing before you can start trial. And, I guess my third question is. On the open label study, what data do you think it would be helpful I guess for investors to look at and to gain greater confidence in your molecule? Thanks.

Thank you, Uy. I believe, Cedric, this question is for you .

Absolutely. Thanks for the question and I'll address them in the order they were asked. So is 302 open for recruitment? Yes, it is, it was moving a little bit more slowly over the past quarter as we worked to streamline the existing protocol and make the necessary amendments to make it a more efficient study and we will add sites to get that study moving ahead at a nice pace. So, it was never closed or paused it was open for recruitment. And now we will re-energize the efforts on that trial with the amended protocol. With regards to the new study and the requirement for FDA blessing to run the study. All studies that we design are submitted to the FDA and so they do have the opportunity to come back and give us the thoughts or the recommendations, but as you can imagine, we've already had quite a bit of dialog with the FDA and we have quite a lot of understanding about what these trials need to look like. So there wouldn't be any anticipated divergence from what the FDA would expect in a trial like this. So it's pretty straightforward. And as to what kind of data come from the open label study would be of interest to the community. I suppose the very fact that running a 12 month open label study allows you to get your necessary safety exposures. That's important for the NDA filing. Looking at -- in an open label setting we were setting rates of adverse events, we'll contextualize what patients might expect once they get this treatment in the future and discontinuation rates always of interest and from the efficacy perspective, it's real world efficacy findings. You can look at the timeline of treatment effect and also then because it's a long-term open label study, you can learn quite a bit about as sustained response and treatment out to 12 months or so.

Okay. Thank you.

Our next question is from Marc Goodman with SVB Securities. Please proceed with your question.

Thanks for taking my question. This is Rudy on the line for Marc. I have a question regarding study 302, you mentioned that study enrolling around 100 patients. So how should we think about the impact of the new enrollment criteria, especially in those patients who are enrolled? And also kind of talk about the powering for both studies with your new product.

Thank you. Cedric you are in great demand today. So it's for you too.

Thanks, Rudy. And if I understood your question, because it was a little bit of kind of metallic sounds to your voice, but I think you were saying what to learn from the first 100 patients in that study and how one should think about the next 200, what I will say is that the most important outcomes for this study around the primary efficacy analysis. There are not changes in that regard. So basically the amendments were aimed at reducing the amount of assessments, the amount of time that the patients were spending at the site in order to control for those issues that we saw, particularly placebo response. And so the primary outcome of interest, efficacy measurement has unchanged and the approach to dosing and evaluating the patients for the purpose of that is very much the same. So with regards to learning from the 301 study, obviously, we can work to -- if one were to assume that maybe the beginning of 302 was similar to 301, obviously, there are ways that we feel confident having discussed it internally and with clinical trialists, design a more efficient second leg of this ongoing study, if you like, to bring us to a positive study. And so that's what we have set out to do by amending this protocol. And with regards to, at this point, powering a statistical analysis, we just would not be ready at this moment to get into those details.

Got it. Thanks.

Our next question is from Andrea Tan with Goldman Sachs. Please proceed with your question.

Hi, everyone. Thanks for taking my question. Maybe another one for Cedric, if you don't mind. Just curious given the receptivity for MDD so far, just wondering if you could speak on updated thoughts on how you would see REL-1017 existing in the treatment landscape there? And are there any learnings that you can take from the early launch so far?

Hi, Andrea, thank you for the question. Cedric, that's definitely for you.

Well, I just -- I think it's tremendous to see new drugs being approved with new mechanisms of action. The MDD patient population continues to be underserved. And so I think it's terrific, the more opportunities we have for approvals, the better. And obviously, there are some similarities between REL-1017 being NMDA receptor antagonist. And I think it's very exciting for that particular realm of mechanisms that there's greater access and people are willing to develop these drugs. And no, I don't think I would -- I haven't really any learnings or insights based on early launch activity or anything like that. I focus on the clinical trial design here.

Andrea, if I may add, Sergio here. Yes, the position in the marketplace that you mentioned and REL-1017, if REL-1017 will be approved, it will be quite a bit different. The REL-1017 is going to be adjunctive. So it will be one single tablet that can be added to any other antidepressant use. And there is no antidepressant approved for that indication, right? The other drug is already a combination, so it's unlikely that would be widely used as an adjunctive to a third to the present. I hope this answers your question.

Thanks Sergio.

Our next question is from Andrew Tsai with Jefferies. Please proceed with your question.

Hi, thanks. Good afternoon. Thanks for taking my question. I appreciate you walking us through these analysis that you did. First question is, what would the very first 303 monotherapy study look if you were to do a similar set of post-talk analysis? Would you get a similar type of signal or a favorable signal for 1017? And then secondly, as we think about RELIANCE II, is there a way to know if the first 100 patients indeed are not tainted. There's no issues basically? Or said another way, why should we feel confident the first 30% of patients or so who have been enrolled in RELIANCE II won't hurt the study outcome because technically some of them could have come from unverifiable sources, correct?

Cedric?

Okay. Thanks, Andrew. So the first question about monotherapy, yes, we did. We did apply the same analysis to the monotherapy study, and again, in the monotherapy study, had a much higher mean change from baseline for placebo of about 14 points, and drug outperformed placebo by approximately 1 point. So it had a higher placebo problem, but the delta was also a little less than what we saw in the adjunctive, but you're right. When we looked at verifiable, unverifiable, pre-pandemic, post-pandemic and different splits of the data and sites, we definitely saw the same issues. So we don't feel that the issues were unique to the adjunctive 302 study, but rather broadly across the RELIANCE program. The decision to pursue adjunctive was a strategic decision really based on the fact that 302 was ongoing with, as you pointed out, 1/3 of patients enrolled. And by improving that design and starting with a new streamlined adjunctive study and new study, that will be the clearest and quickest path to filing for the indication of adjunctive treatment of MDD with the agency. Now the question as to whether can you know anything from the first 100 subjects? Well, you can't really because it blinded. What you can work on is, you can look at how your studies did over time. And we spent a little bit of time pointing out the pre-pandemic or after the restrictions were lifted and the impact and how the delta improved. And so we do think that maybe the later part of the 301 study is more reflective of the early part of the first 100 patients that we have in 302. And some other thoughts about sample sizing, gave us confidence to say, well, if we had an original target of about 300 patients, these trials -- the opportunity for the drug to separate despite all those challenges would exist. And so we've done a number of modeling exercises and talking to statisticians and talking to the clinical sites. And so yes, we -- to answer your question directly, we feel pretty confident that with the amended protocol and with the considerations around target sample size, this study could indeed be positive.

Andrew, also consider that the -- if you look at the data from the top down, the major impact on Study 301 was focalized, localized on two sites that enrolled about 40 patients together. These two sites that were not -- never been presence in Study 302.

Right, right. Okay. And then one more is just on the 304 study RELIANCE IV. Are there any differences in the study design relative to RELIANCE II, the ongoing one? And does it make sense to start a RELIANCE V, actually?

Well, let me start with RELIANCE IV before we talk about RELIANCE V. But with the 304 new study, it will be significantly different in terms of the various scales and assessments that we will -- we will be asking the raters and the PIs to administer with the patients. Now there are a couple of standard things that you don't change like your primary efficacy outcome measure. But again, it's much easier to start with a blank slate than it is to amend the protocol to kind of remove things. So it will be very similar in terms of 2-arm study, four weeks in duration, primary efficacy outcome, the same, and there will be less exploratory secondary endpoints just so that we can really focus in on the efficacy.

Very helpful. Thank you, guys.

Our next question is from Jay Olson with Oppenheimer. Please proceed with your question.

Hi, guys, thanks for the update. And thanks for the question. First question is for Cedric. Could you please talk about any due diligence that you did prior to making your decision to join Relmada? And what do you learn from your peers or KOLs that you may have spoken to about REL-1017? And what do you consider to be the most important capabilities for the Chief Medical Officer to optimize the probability of success for MDD clinical trials? And then I have a follow-on, if I could, please.

Thank you for that question. And I'm delighted to be part of the Relmada team. They're very thoughtful professional group of people. I've only been here since January 6, but I already feel part of the family. And when Sergio first reached out to me and asked would I be interested in taking the role, you're absolutely right. I did want to look at the data under CDA and understand what went wrong in the study and if I still believe that the drug had efficacy potential. And if it did, what could I reasonably come in and suggest be changed in order to optimize the signal. So it was very obvious in my mind, and the key opinion leaders and thought leaders that you mentioned that when I looked at the placebo response, one and all acknowledge that this was an uncontrolled placebo response, and it's very hard to draw any conclusions if you hadn't kept it to about 10 points, you really couldn't say one way or the other about the drug. So then I wanted to look at the protocols as they were run and see if I had ideas coming into the design of the trial that I feel I could actually be of help or benefit to them. And so I think that by everything that we're trying to do right now, streamlining the protocols, I believe that can be achieved. And was that -- was there a second part to your question?

No, I think that's everything. That's super helpful. I did have one follow-up question on RELIANCE II when you see the results. How do you plan to evaluate patients who enrolled pre versus post protocol? And then, and is the study powered for a subgroup analysis of pre versus post protocol amendment? And what influence do you expect to see on the results on the protocol amendment. Thank you.

What is the review? Do you want to answer that?

Well, the second part first, the effect on the results, I'm hoping to control for placebo response because I won't feel like I succeeded in my job unless I can bring placebo response down and that will -- that should widen the delta, the drug placebo difference because one thing that REL-1017 has had in common across all the trials is the same magnitude and trajectory of improvement. And so if we can keep placebo down, I would expect to see a nice separation. And the first part of the question related to -- remind me.

Evaluating patients pre versus post protocol.

Yes. I mean, we are definitely looking at that and intend to do that as part of the analysis plan, but the specifics of that, I just wouldn't be ready to get into detail of it just yet with you. But it's a great and important demarcation in terms of data announcement.

Jay, we did -- Sergio here. We did -- we made a conservative assumption on the first 1/3 of the patients. We assume that the data will be similar to what we have seen in 301. And we also made assumption conservative on what the next 2/3 of the trial patients should be to make the study successful and reach the conclusion that it's definitely worth to move forward and complete the trial.

Okay, great. Thank you. That's super helpful. Appreciate that, Sergio. And thank you both.

Thank you.

We've reached the end of the question-and-answer session. I would now like to turn the call back to Sergio Traversa for closing comments.

Thank you very much. And in closing, I remain grateful to the Relmada team for their continued hard work and dedication to executing on our mission. I would like also to extend my sincere thanks to the participants and clinical partners involved in the REL-1017 trials for the effort in advance of this important product candidate through the clinic. With that said, thank you very much to everyone, and I wish to everyone a good end of the day. Thank you.

This concludes today's conference. You may disconnect your lines at this time, and we thank you for your participation.
