spk05: Thank you, Mark. Sorry about that, everyone.
spk08: Good afternoon, and thank you for joining our call. Visagen's fiscal 2024 was filled with a series of remarkable accomplishments, most notably with the positive results from our Palisade II U.S. Phase III study of fastidionol for the acute treatment of social anxiety disorder. Visagen became the first company to achieve a positive Phase III study with a drug candidate for the acute treatment of SAD. In addition, with the potential to complement Palisade 2, we recently launched our Palisade 3 phase 3 trial, marking that as the next major step forward in our registration-directed Palisade phase 3 program for Fasadionol and SAD. These significant achievements and progress across our diversified pipeline of novel neuroactive faring candidates reflect our commitment to pioneering neuroscience that's anchored in a deep understanding of nose-to-brain neurocircuitry, focused on developing differentiated drug candidates with potential to set new standards of care for underserved patients affected by high-prevalence neuroscience disorders. As a brief reminder to some and as an introduction to others, our diverse clinical stage neuroscience pipeline features a new class of neuroactive intranasal product candidates known as pharynx. Exclusively designed as nasal sprays, our farine pipeline leverages an innovative approach to treating psychiatric and other neuroscience disorders by using the nose as a portal for the administration of novel, rapid-onset, neurocircuitry-focused drug candidates that do not require systemic absorption or binding to neurons in the brain to achieve desired therapeutic effects. Administered in microgram-level doses within milliseconds, each member of our new class of pharynx activates peripheral chemosensory neurons in the nasal cavity, influencing fundamental neurocircuitry in both the olfactory system and the brain. With unique proposed mechanisms of action, or MOAs, our non-systemic neurocircuitry-focused pharynx have demonstrated favorable and differentiated safety profiles in all clinical studies completed to date. Thorium is to develop and to commercialize a diversified pipeline of neuroactive ferrines for multiple high-prevalence CNS disorders, such as social anxiety disorder, major depressive disorder, and menopausal hot flashes, indications with limited differentiated FDA-approved treatment options, and inadequate or even nonexistent current standards of care. For example, social anxiety disorder, which is a neuropsychiatric disorder that's marked by profound fear and anxiety of social and performance situations in everyday life. They're often triggered by social media and team orientation in the workplace or in academic settings. The disorder that affects more than 30 million U.S. adults, yet despite the high and seemingly ever-growing prevalence of SAD, there is still no FDA-approved acute treatment. help individuals rapidly and safely manage their anxiety symptoms when faced with social and performance stressors in their everyday life, especially when they are faced with multiple different anxiety-provoking stressors during any single day and at different times in that day. Our Phase III program for quercidinol intends to help close that treatment gap for the millions of underserved individuals that are affected by SAD without an adequate option for a rapid flexible, and patient-controlled treatment. Building on our success during fiscal 24, our registration-directed Palisade Phase III program for Fasadienol for the acute treatment of SAD is progressing on track, including enrollment in our recently launched Palisade III trial, which is on track for top-line data mid-year in calendar 2025, as well as preparations for our upcoming Palisade IV trial that we expect to initiate in the second half of this year and complete before the end of calendar 2025. Both phase three trials are designed with the potential to replicate our successful Palisade 2 phase three trial. While the public speaking challenge design of Palisade 2 and the use of the subjective units of distress scale or SUDS is the primary efficacy endpoint and the studies are unchanged, We've built some notable enhancements into Palisade 3 and Palisade 4 and made some operational changes we believe will help optimize quality enrollment, enhance surveillance, and control potential variability, as well as drive rigorous protocol adherence during execution of Palisade 3 and Palisade 4, all against the backdrop of what is now a far more favorable and stable clinical research environment than at any time during the pandemic. During the second half of 2024, we also plan, we're also planning to initiate a small placebo-controlled repeat dose study in alignment with our discussions with the FDA to evaluate the effects of a second dose of fastidionol administered 10 minutes after the first dose prior to a public speaking challenge. Similar to Palisade 4, we anticipate completing this study in the second half of calendar 2025 with a top-line readout near the end of calendar 2025. We believe success in either Palisade 3 or Palisade 4, combined with the positive results from Palisade 2 and additional open-label safety data from all Fasadionil clinical trials to be completed next year, may provide substantial evidence of Fasadionil's effectiveness and safety to support submission of a potential u.s new drug application for the acute treatment of sad during the first half of 2026 which if approved could be the first approval of its kind as a reminder the fda has granted fast track designation for our development of fastidionol for the acute treatment of sad we are also actively exploring the therapeutic potential of our fairing itruvone another non-systemic varying candidate with the potential to be a new and fundamentally differentiated therapy for major depressive disorder, or MDD. Preparations and planning for U.S. Phase IIb development of ytruvone and MDD are ongoing. Our mission in this large and increasingly prevalent neuropsychiatry market is to transform the standard of care, expediting the time of frame in which individuals may find relief of their MDD symptoms with a new rapid onset product candidate with a differentiated safety profile that is not associated with unwanted side effects and safety concerns such as sexual side effects, weight gain, or abuse liability. We also see significant medical and commercial potential in PH80, a rapid-onset, non-systemic, hormone-free barine nasal spray candidate for women's health indications. During fiscal 2024, we announced positive data from two previously unreported placebo-controlled exploratory Phase IIa studies conducted outside the U.S. PH80 demonstrated statistically significant results both as a treatment for vasomotor symptoms or hot flashes that are due to menopause and for the management of premenstrual dysphoric disorder or PMDD. We are currently conducting U.S. IND-enabling non-clinical studies with the potential to facilitate further Phase II clinical development of PH80 for menopausal hot flashes in the U.S. which is another high prevalence indication affecting approximately 80% of women ages 45 to 65. Current treatment options that are not satisfactory or suitable for millions of those women worldwide. We're also pleased to enter into an exclusive negotiation agreement with Fuji Pharma, which is a leading women's health-focused company in Japan during fiscal 24, focused on negotiating exclusively for a potential license agreement with them for the development and commercialization of PH80 in Japan. On a corporate level, Physiogen received Mental Health America's prestigious Platinum Bell Seal Award during the first quarter of fiscal 2024, and again in the first quarter of the current fiscal year. We also received the esteemed Great Place to Work certification, with each of these awards reflecting our commitment to be a company that exceeds workplace practices and standards intended to promote and support mental health and the well-being of our employees, while also playing a key role in promoting and advancing a broad societal shift toward destigmatizing mental illness. With that, I'll now turn the call over to our CFO, Cindy Anderson, to summarize some of the highlights from our Fiscal 24. Cindy?
spk00: Thank you, Sean. As Sean mentioned, I will highlight a few financial results. from our fiscal year 2024. I also encourage everyone to review our report on Form 10-K filed with the SEC earlier this afternoon for additional details and disclosures. Research and development expenses were $20 million for the year ended March 31, 2024 as compared to $44.4 million for the year ended March 31, 2023. This decrease in R&D expenses was primarily due to a decrease in clinical and development expenses related to the timing of expenses incurred in our Phase III trials of Fasunilidol and SAD. General and administrative expenses was $14.1 million for the year ended March 31, 2024, as compared to $14.7 million for the year ended March 31, 2023. The decrease in G&A expenses was primarily due to a decrease in professional fees and stock-based compensation expense, offset by an increase in compensation expenses. Our net loss attributed to common stockholders was 29.4 million for the year ended March 31, 2024, compared to 39.2 million for the year ended March 31, 2023. As of March 31, 2024, we had cash and cash equivalents of 119.2 million. As a reminder, please refer to our annual report on Form 10-K that was filed today with the SEC for additional details and disclosures. I will now turn the call back over to Sean.
spk08: Thanks, Cindy. So, as we conclude our prepared remarks, I just want to underscore the hard work and the commitment, as well as the pride and enthusiasm of our team around our potential to improve the patient lives. We're focused on helping and to deliver value to our stockholders. With the commencement of our Palisade III and the pending launch of our Palisade IV phase III trials for fastidionyl targeting the acute treatment of SAD, a market with increasing prevalence now topping 30 million Americans, we are systematically executing our registration-directed program with the potential to achieve the first FDA approval for that indication. We have great confidence in our team's expertise. and executing our Palisade Phase 3 program and all the programs across our neuroscience pipeline. So, on behalf of the entire team at Vistagen, I'd like to thank you for your ongoing interest and for your support.
spk04: Thank you, Sean. Operator, we would now like to open up the call for questions from the cell-side analysts participating on the call today.
spk02: Thank you. Ladies and gentlemen, if you'd like to ask a question, please press star 1 on your telephone keypad, and a confirmation tone will indicate your line is in the question queue. You may press star 2 if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. And our first question comes from the line of Andrew Tsai with Jefferies. Please proceed. Hey, good afternoon, and congrats on the progress.
spk03: This is Matt on for Andrew. And I just had a couple of questions, if you don't mind. In Palisade 3, how many patients have you enrolled so far? And is the enrollment cadence looking stronger or slower than the first couple of studies? And then also, if you don't mind commenting on the screen failure rate and how that compares to the prior studies as well. Thank you.
spk05: I'm sorry, I didn't catch your name. Matt, thank you. Oh, hey, Matt.
spk08: So we haven't given any guidance on enrollment, all on specifics of enrollment and screen fail rates and the like. But what I can tell you is what I emphasized during the prepared remarks, which is we're very happy with the way that Palisade 3 has kicked off. We've been able to build in some really important efficiencies, not only throughout the execution of the study, but up front even between lead generation and actual enrollment through Visit 1 and the screening. And we've been able to achieve a lot of the things that reflect and leverage the lessons learned through the course of the prior execution of studies of this particular design, leading all the way back to phase two time. So, I think our team is extremely well positioned to continue this study on track and the same be the case for Palisade 4 with the ability to achieve the readouts right around the time that we've we've guided, which would be mid-25 and then near the end of 25 for Palisade 4.
spk05: Okay, got it. Thank you. Josh, do you have anything to add to that? Josh? Yes, I would just, yeah. Hello, Sean. Yes, thanks.
spk07: I would just say that we are, you know, pleased with the startup of both of Palisade 3. that it's meeting our expectations in terms of recruitment rates, in terms of screen failure rates, those types of things. So at this point, we're very pleased with our progress.
spk05: Thanks, Josh.
spk02: And the next question comes from the line of Paul Matisse with Stifel. Please proceed.
spk01: Hi, there. This is Julian on for Paul. Thanks so much for taking our question. You described a couple of notable enhancements that you made, things like operational changes, enhanced surveillance, etc. Do you mind just providing a little bit more color on what exactly you're doing and why that gives you greater confidence as you continue enrolling Palisade 3 and soon Palisade 4? And then just really quickly, one quick question. On the repeat dose study, do you mind Do you mind telling us just what you're looking to achieve here, and is this more about building the safety database, or is this more about replicating efficacy with a multi-dose paradigm? Thank you.
spk08: Great. Hey, thanks, Julian. Appreciate the questions. So just to be clear right up front, the public speaking challenge design will remain the same across Palisade 2, 3, and 4. So, as will the SUDs as the primary efficacy endpoint. So, no changes there. Those will continue, again, to remain consistent throughout the development of FASTA dial for the acute treatment of SAD. And that's been the case all the way back to phase two. So, the refinements that we made to palcate three and four really are based, again, on experience that we have very unique and extensive experience scaling up to a large phase three study. that come from our observations of the conduct of the Palisades Phase III program from, again, the early through the late stages of the pandemic in particular. So, the enhancements to Palisades III and IV apply primarily to ensuring that we've got optimal subjects in the study, real extensive, precise, and universally applied screening, inclusion and exclusion criteria, and that the public speaking challenge protocols administered properly and consistently with limited variability. For example, one of the exclusion criteria that's been added is limiting high-frequency smoking or vaping, THC use, signs of COVID or any recent nasal swabs, all of which could have some sort of an impact possibly on receptors and impact a single-dose public speaking challenge. Josh, maybe talk about some of the other things that you and the team have been seeing some really significant benefits on as we've even pre-startup and now as we've gotten into the execution of Palisade 3.
spk07: Yeah, absolutely. I think two of the key things you touched on, Sean, are our experience of going through Palisade 1 and Palisade 2, but then also being able to operate in a pandemic-free environment as we got Palisade 3 up and running and as we look forward to getting Palisade 4 up and running. It's just allowed us to really drive consistent execution across sites to reduce the potential variability. I mean, it's really around changing our approach to both study monitoring and our staffing model, right? So it gives us rigorous training of sites and then oversight of study conduct. So if you think about where we are with Palisade 3 compared to Palisade 1 or 2, you know, we had an in-person investigator meeting for Palisade 3. So we had that, you know, face-to-face in-person training of, PIs, raters, study coordinators, which we couldn't do in one and two. And then as we've gotten sites up and running, kind of that startup process, we've already had more in-person site visits in Palisade 3 than we did in either a Palisade 1 or Palisade 2 because of the restrictions of the pandemic. And so that new site-facing staffing model, just giving us a lot more oversight and increased level of site communication to make sure that the studies are going the way that we want them to.
spk08: I also add that we've eliminated mask wearing in these Pal State 3 and 4 by either the subject or the public speaking audience and also the The drug dose will be administered by the healthcare provider just to ensure, again, proper dosing for the study. So a lot of little small things as well as some significant changements, all intended to really enhance and optimize surveillance, control variability, the things that actually, you know, make a difference on outcome. But those are some significant mitigators, we think, to some of the risks that are typically associated when you're scaling up to a multiple center study. And then as to the repeat dose study, I'll let Josh speak to that in a minute as well. But again, we're in line with what the FDA has been discussing with us for a while on that one. And while there could be some safety benefits from the study, we also think it also could have some benefits on labeling. So, Josh, I want you to just amplify a little more on what we've been thinking on the repeat dose study.
spk07: Yeah, absolutely. It's essentially the same design as Palisade 3 and Palisade 4. just with the addition of an additional dose 10 minutes after the first, and then the subject moves into the public speaking challenge. The reason we're doing the study is because the FDA specifically asked and said, you know what, in the real world, patient might still feel nervous after a first dose and want to take another dose. So we'd like you to, you know, kind of see what happens in that instance. And so that's why we're doing that. Really for the purpose of, you know, informing the label, for informing physicians on how they should advise patients. And the other piece to that is we will have an open label extension or we plan on for that study. And so that'll let us kind of see again in the real world, you know, what happens if patients are able to use the product again within 10 minutes and whether or not they, you know, they even do. So again, it informs the label and informs physicians on how to advise patients. And then finally, it's just to clarify, it's three arms. So it's, you know, placebo, followed by a placebo, fasciodynol dose, followed by placebo, and then fasciodynol dose, followed by fasciodynol for the three arms.
spk08: It's key to remember that these pharynx, they activate the chemosensory neurons within milliseconds. There's also a limited capacity for the nose to accept the volume of spray. So, we're actually not expecting much, any really safety-related concern associated with the multiple dosing, but it does, as Josh noted, it has the potential to help inform labeling and give some guidance to, which we do think is certainly safe, which is if someone were to dose it more frequently than, say, every hour, which is the typical duration of effect of Fasodil that we've seen in prior studies.
spk05: Excellent. Thank you for the details.
spk02: And then the next question will come from the line of Tim Lugo with William Blair. Please proceed.
spk06: Thank you for the question and congratulations on all the progress for PAL-3. And I guess my question relates to PAL-3. How many sites are up and enrolling patients? And of those sites and maybe the planned sites for PAL-3, how many of those sites also overlap with PAL-1 and PAL-2?
spk08: Thank you, Tim. I appreciate the question. So one of the good things about having the experience that we've got within the clinical research community is the ability to really assess sites that we think play at a varsity level and others that might not be quite there. And the emphasis certainly for what we're putting together for both of these phase three studies to try to replicate Palcate 2 is what we hope and believe is a varsity squad. Some of them do overlap from the prior studies. I think right now what we publicized, Josh, I'm not sure if we got them up today, but it should be right around 10 sites up. So it's on a good pace for Palisade 3. And some of them will have been in one or two. But all of them uniquely, as we've talked about, even if they have been before, we know there's always a benefit. We've seen it with the fact that this is the third time that this protocol after a very long drought, really nothing in social anxiety disorder, let alone for the acute treatment, like we said, we've never seen. There's a lot of good experience and understanding and really positive read through that we've seen at a lot of the scientific conferences where we presented Palisade 2 data. There's a great level of awareness, even sites and then PIs not involved in the program about what we're doing. the MOA associated with this class of drugs and this one in particular, and how what we're seeing is really a fundamentally differentiated approach and a drug candidate for what's been a challenge for practitioners for a very long time, which is to have something that a patient can use flexibly, control the use of it, use it multiple times a day and even different times of day for different stressors on a certain day, and then have the ability to not use it on days when they're not stressed and don't want any medication of any kind, even a super safe one, in their body. So I think the benefit is the pool of potential sites and the sites that we actually expect to see in these two studies is not only expanded, but of a much higher quality than we've ever seen before at this point. And a lot of that's due to our own work, but it's also due to the awareness of the need And especially because there is no, not only is there not an approved treatment, acute treatment for SAD, but even the available therapies for use on an off-label basis just fall way short of what this population seems to need to be able to be unimpaired cognitively, not worry about abuse liability, and to be able to really control and fit a medication to their life and the circumstances in their life that debilitate them and create and generate significant opportunity costs. So I guess, Tim, the bottom line is we really expect to have universal varsity programs on both Palisades III and IV, and a lot of that has to do with the way that we manage these studies. It's not just a quick in-person investigator's meeting, but it's kind of like painting the Golden Gate Bridge up by you. And that is you start and you go through the sites and you go back through the sites and back through the sites. And we're also not seeing the type of attrition and staff turnover at sites and at CRO with CRO support that was the case often through the pandemic. So there's a normative sense now within the clinical research community, at least for our neuropsychiatric focus for this program, that we're just really excited that the enhanced enhancements to the protocol on top of a more stable environment is a really good combination.
spk06: Thank you for that. And I guess one more question for the small placebo-controlled repeat dose study. You mentioned for labeling purposes, will there be a sub-score recorded prior to the repeat dose and then after the repeat dose? Or is it more of a safety and tolerability type of study?
spk07: Yes, there absolutely are SUDS scores collected, identical to the SUDS scores that are collected in Palisade 3 and Palisade 4. So, there's kind of the pre-speech SUDS, and then once the speech starts, obviously those SUDS are captured for the primary endpoint. So, the actual endpoints will be identical to those in Palisade 3 and 4.
spk06: Will certain non-response after the first dose trigger that second dose, or do you just collect all the data and let people, if they feel like they need to redose, let them redose?
spk07: In the public speaking challenge portion of the study, if you recall in the study design, there's a 15-minute waiting period after the subject takes the dose. That second dose is administered in that same period, and You know, we think that the activation with fastidinol is almost instantaneous, we think, but in terms of the clinical study, we wait 15 minutes before the subject engages in the public speaking challenge. And so it's really during that waiting period where that second dose is administered. So then beyond that, the study is identical to Palisade 3 and 4.
spk06: Oh, okay. So it's potentially two doses before the public speaking challenge, not
spk05: Correct.
spk06: One dose, public speaking, then another dose. Correct. Oh, okay. Thank you so much. Correct. Yep.
spk04: Operator, I believe that's all the time we have for questions today. If there's any additional questions, please do not hesitate to contact us by email at IR at Vistagen or via the contact section of our website. We also encourage you to register for email updates on our website to stay connected to the latest news from Vistagen. Again, thank you all for participating on our call today. We appreciate everyone's interest and support. We look forward to keeping you current on our continued progress. This concludes our call. Have a magnificent day.
spk02: This concludes today's conference. You may now disconnect your lines at this time. Enjoy the rest of your day.
