Earnings Call Transcript 2024-Q1

[Operator]

Good day, and thank you for standing by. Welcome to the MindMed Q1 2024 Earnings Conference Call. [Operator Instructions] Please be advised that today's conference is being recorded.

I would now like to hand the conference over to your first speaker today, Rob Barrow, CEO of MindMed. Please go ahead.

[Robert Barrow, executive]

Thank you, and good afternoon, everyone. Welcome to our first quarter 2024 financial results and corporate update conference call. The press release reporting our financial results is available in the Investors & Media section of our website and our quarterly report on Form 10-Q for the quarter ended March 31, 2024, is being filed today with the Securities and Exchange Commission.

During today's call, we will be making certain forward-looking statements, including, without limitation, statements about the potential safety, efficacy and regulatory and clinical progress of our product candidates, our anticipated cash runway and our future expectations, plans, partnerships and prospects.

These statements are subject to various risks such as changes in market conditions and difficulties associated with research and development and regulatory approval processes. These and other risk factors are described in the filings made with the SEC, including our annual report on Form 10-K and our Form 10-Q being filed today.

Forward-looking statements are based on the assumptions, opinions and estimates of management of the date the statements are made, including the nonoccurrence of the risks and uncertainties that are described in the filings made with the SEC or other significant events occurring outside of MindMed's normal course of business. You are cautioned not to place undue reliance on these forward-looking statements, which are made as of today, May 8, 2024. MindMed disclaims any obligation to update such statements even if management's views change, except as required by law.

Joining me on today's call are Dr. Daniel Karlin, our Chief Medical Officer; and Dr. Francois Lilienthal, our Chief Commercial Officer.

Earlier today, we announced the transition of Schond Greenway, who as of May 3, is no longer serving as our Chief Financial Officer. On behalf of the Board and the company, I want to thank Schond for all of his hard work and dedication to our mission over the past 2 years and wish him the best of luck in his future endeavors. We retained an executive search firm to assist in identifying a new Chief Financial Officer to support the next phase of MindMed's growth in Evolution.

Moving back to our first quarter results. We are excited to be providing this financial and business update during this important period for MindMed. It has been a fantastic start to the year and a highly productive quarter for MindMed, which was highlighted with a positive 12-week data from our Phase IIb clinical trial for MM-120 in the treatment of generalized anxiety disorder or GAD.

Alongside the data, we were thrilled to announce that FDA designated MM-120 as a breakthrough therapy in the treatment of GAD. This designation is reserved for therapies that are intended to treat a serious or life-threatening condition and for which preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies. We believe receiving this FDA designation in the positive Phase IIb trial data we shared reinforces MM-120's potential as an emerging best-in-class product compared to today's standard of care.

On the heels of the MM-120 data in March, we completed a successful oversubscribed underwritten offering and concurrent private placement raising approximately $175 million in gross proceeds before deducting transaction fees and other offering-related expenses. Participants in the offering included some of the most respected blue-chip institutional health care investors, which we believe further validates the great work that we have been able to achieve in the past year.

Most importantly, this financing puts MindMed in its strongest financial position ever, and we expect that it will fund the company through important development milestones for MM-120 and other programs in our pipeline.

Finally, we announced several scientific posters and presentations that we have shared at various medical meetings. In April, we presented posters of the European Psychiatric Association's 2024 Congress in Budapest, Hungary, and then Anxiety and Depression Association of America 2024 Conference in Boston. This month, we presented detailed results of the American Psychiatric Association's 2024 Congress and at the International Society for Pharmacoeconomics and Outcomes Research.

These poster presentations cover data from our Phase IIb trial of MM-120 and GAD, as well as studies related to the epidemiology and growing burden of GAD, which we believe remains underappreciated. Additionally, our collaborators from University Hospital Basel will be sharing 1-year follow-up results from a Phase II investigator-initiated study of lysergide in the treatment of anxiety disorders as the Society of Biological Psychiatry 2024 Annual Meeting being held May 9 through 11 in Austin, Texas.

Overall, increasing our visibility at these key scientific meetings represents an important strategic initiative for MindMed in 2024 as we look to expand awareness of our work and build MindMed's profile within the scientific community.

Our progress comes at a crucial time with an urgent need for better treatments to address the epidemic of brain health disorders. A situation that has grown significantly worse over the past several years.

In our lead indication, GAD, for example, a recent mental health prevalence study that was prepared for the Substance Abuse and Mental Health Services Administration, found that 10% of U.S. adults report having symptoms consistent with the GAD diagnosis, making it the second most common mental health disorder among adults 18 to 65 years old. In comparison to historical studies or the prevalence of GAD, the condition appears to have tripled in the last 2 decades alone.

Our MM-120 program in GAD has seen an extraordinary progress over the past year, culminating in the 4-week data from our Phase IIb trial that we announced in December 2023, and the subsequent positive 12-week follow-up data that we shared in March. Results have exceeded our target product profile for MM-120, demonstrating a significant improvement in all analyzed endpoints for up to 12 weeks after just a single dose and without any additional therapeutic intervention. We believe these results demonstrate the fast-acting and durable clinical activity of MM-120 along with a favorable tolerability profile.

In the context of currently available therapies for GAD, these data represent a major step forward in a field that has suffered from practically no innovation in the past 20 years. The [ Collins D ] standardized effect size of 0.81 in the 100-microgram dose group at 12 weeks is more than double the estimated effect size of the current standards of care for GAD which are estimated to have effect sizes below 0.4 on average. We believe this result can wholly be attributed to the stand-alone effect of MM-120 as the trial was conducted in the absence of any other therapeutic intervention.

We also reported results from our MM-120 PK bridging trial evaluating the MM-120 orally dissolving tablet, or ODT formulation that delivered upon our clinical aspirations for the new product formulation. The ODT formulation provides numerous benefits, including extending MM-120's intellectual property profile as well as product performance benefits such as enhanced bioavailability and increased area under the curve of therapeutic concentrations that further differentiates MM-120's clinical profile.

Overall, the characteristics of the ODT formulation demonstrated in the PK bridging trial off of what we believe is a compelling evidence for its differentiated clinical profile and supports our decision to progress the ODT formulation into Phase III development.

With this exciting progress, we believe we have successfully achieved the goals of Phase II development for MM-120 and expect to advance MM-120 into pivotal Phase III clinical trials for GAD. We anticipate having an end of Phase II meeting with FDA in the second quarter of 2024 to align on the scope of our Phase III development program and to initiate our Phase III clinical program in the second half of 2024.

Additionally, based on the promising data we have observed for MM-120 in indications beyond GAD, such as depression, we are actively evaluating additional clinical indications and believe the overall development program for MM-120 may represent the best-in-class treatment for GAD and beyond.

As we build momentum in development of MM-120, we are also strategically enhancing our focus towards commercial planning. As you may recall from our Analyst Day in March, market research shows strong enthusiasm for MM-120 with 74% of surveyed health care practitioners, indicating that FDA-approved psychiodelic treatments will change their approach treating anxiety and depression. This positive sentiment aligns with the success of Johnson & Johnson's [ Bravado ] or [ intranasal esketamine ], which is rapidly approaching blockbuster status. [ Bravado's ] impact extends beyond its own use case as it has helped pave the way for the interventional psychiatry model.

This established model includes well-defined patient care reimbursement pathways, REM's documentation processes and logistics infrastructure, all of which we believe can be readily leveraged for MM-120, a successful in clinical trials and ultimately approved by the FDA and marketed.

Our second lead program is MM-402, which is the [indiscernible] of MDMA. We believe MM-402 holds promise for potential prosocial effects and favorable tolerability profile versus racemic MDMA or the [ S&N ] tumor. The focus of our MM-402 program is to develop a regularly administered product that treats the core symptoms of autism spectrum disorder, or ASD, in particular, social communication difficulties.

Remarkably, despite the significant and increased prevalence of ASD, there are currently no approved therapies specifically targeted at its core symptoms. With robust preclinical evidence supporting our approach, we have initiated our first clinical trial of MM-402, a single ascending dose trial in adult healthy volunteers in the fourth quarter of 2023.

This Phase I trial is intended to characterize the tolerability, pharmacokinetics and pharmacodynamics of MM-402 and will enable further clinical studies to characterize the effects of repeated daily doses of MM-402 and the exploration of early signs of efficacy in the ASD population.

And currently, our collaborators at UHP conducted a comparative Phase I pharmacokinetic from pharmacodynamic trials, RS, R(-)-MDMA with data anticipated in the second quarter of 2024. We believe that the results from this trial will expand and expedite our understanding of MM-402's [ pharmalogical ] profile as we progress into later-stage clinical development.

We'll now turn to our financial results for the quarter ended March 31, 2024. As of March 31, 2024, the company had cash and cash equivalents totaling $252.3 million compared to $99.7 million as of December 31, 2023. We believe that our cash and cash equivalents will be sufficient to fund our operations into 2026 based on our current operating plan.

For the quarter ended March 31, 2024, net cash used in operating activities was $16.6 million compared to $13.3 million for the same period in 2023. Research and development expenses were $11.7 million for the quarter ended March 31, 2024, compared to $12.6 million for the same period in 2023, representing a decrease of $0.9 million. This decrease was primarily due to decreases of $0.6 million in expenses related to our MM-402 program, a decrease of $0.5 million in expenses related to preclinical activities, partially offset by an increase of $0.3 million in internal personnel costs as a result of increasing research and development capabilities.

General and administrative expenses were $10.5 million for the quarter ended March 31, 2024, compared to $8.3 million for the same period in 2023, an increase of $2.2 million. The increase was primarily attributable to increased stock-based compensation expense of $1.1 million and an increase of $0.7 million in personnel-related expenses due to an increase in head count to support the growth of our business.

Company's net loss for the quarter ended March 31, 2024, was $54.4 million compared to $24.8 million for the same period in 2023. This increase was primarily due to changes in the fair value of the 2022 U.S. dollar financing warrants of $27.7 million.

In conclusion, this is a very exciting time for MindMed. We believe that the data on MM-120 and GAD that we share validates our scientific understanding of MM-120's mechanism of action and shows the potential for an emerging best-in-class product profile compared to today's standard of care. We are excited to be on the cusp of moving forward into Phase III with this program, which we currently expect in the second half of the year following our anticipated in the Phase II meeting with FDA.

Before concluding our call, I want to explain my sincere appreciation and gratitude the critical work and unmatched execution that has brought MindMed ever closer to realizing our mission. I would like to thank our highly talented and deeply committed team, our research collaborators and clinical investigator teams, our investors and the many other individuals who have been supported, including especially our patients and their families. We are working tirelessly to deliver on the therapeutic potential of our pipeline and to transform the treatment landscape for the many individuals living with brain health disorders.

With that, I'd like to thank you all again for joining us today, and I'm happy to take any questions.

[Operator]

[Operator Instructions] Our first question comes from Rudy Li from Leerink Partners.

[Guofang Li, analyst]

Congrats on the progress. So [indiscernible] just announced that the FDA is hosting an [ AdCom ] meeting for its MDMA therapy PTSD. So can you maybe talk about the implications to MM-120 and just curious what are the key topics that you're looking at for this AdCom meeting?

[Robert Barrow, executive]

Yes. Thanks so much, Rudy. I'll start it off and instantly invite Dr. Karlin to comment as well.

We certainly, I think, as a field, and we as a company expected advisory committee for any first entrant drug classing, it's important to draw a clear distinction between the mechanism of action, the message of how MDMA is administered in ICOs clinical program for PTSD. And the distinct way in which MM-120 is being developed and studied, but they're generally we would expect there to be an advisory committee for novel treatments such as this. So I think there has been some commentary publicly trying to read into this and hope there's much to be read into and all of us across the board we feel and expected to be occurring.

In terms of subject matters [indiscernible] will be following very closely and looking to understand points of interest for the advisory committee. And we've seen the [ ICER ] report on [ LYCOS ] program. We have intentionally from day 1, designed our program to answer many of the key questions that have been presented in our field and they are covered in FDA's guidance and feel very confident that we will continue to demonstrate to best-in-class scientific rigor and approach to addressing those questions.

But [indiscernible] will follow the areas of interest from the advisory committee members and look forward to hopefully a successful outcome for [indiscernible] and MDMA?

[Operator]

Our next question comes from Brian Abrahams from RBC Capital Markets.

[Brian Abrahams, analyst]

At the recent APA presentation, you showed some trends over time in both HAM-A and PGIS, and it looked like directionally, they were similar, but maybe there were some subtle differences there. I was wondering if you could talk about that and just, I guess, how that's impacting what your base case is here for the durability of the administration based on both this and other evolving data?

And then secondarily, I think the mattress change here, I think, really underscores what could be potential antidepressive effect. And so I know you sort of alluded to it a little bit in the prepared remarks, but I'd be curious to hear what more specifically -- what some of the factors that you guys are going to be considering in determining whether or not to move this forward in major depressive disorder or other depression indications and I guess how you're thinking about what the potential indications might be there.

[Robert Barrow, executive]

Perfect. Brian. I'll turn it over to Dan to talk about your first question, then I'll maybe address the second one. Dan?

[Daniel Karlin, executive]

Yes, absolutely. And thanks so much for the question. So when we look across all of the different measured data that we've shown publicly so far, what we see is directional agreement and to a very large extent, magnitude agreement as well. So in general, each of these different scales gives us confidence in the different domains that they pick up that the effect we're seeing is real, is not an artifact of 1 particular scale or 1 [indiscernible] method of administering a scale. Of course, as CGI collected by a blinded radar is going to reflect slightly different things than a PGI that may be more determined by a patient's individual experience in the treatment.

But particularly the fact that we're seeing week 12 slight degradation on the PGI, it doesn't give us any concerns about the robust activity of the drug, particularly since we're seeing such strong significance across the clinician-rated measures. Rob, do you want to speak about [indiscernible], or do you want me to?

[Robert Barrow, executive]

Yes, absolutely. I would just note, too, on that first point, Brian, that obviously, the HAM-A value scale is the gold standard for anti-anxiety approval. So that's where we're going to be focused in our dialogue with FDA. Again, we look at -- while we talk about the pairwise comparison here, you have to remember that he was a large 200-patient study. We had robust power and statistical conclusions on the HAM-A. Certainly, we're looking at the secondary endpoint looking at pairwise comparisons we're talking about around 40 patients per arm in the Phase II study. So that has progressed and look at the numerical changes even those would be -- likely to be [indiscernible] significant if we saw the same effects in a larger population.

In terms of the depression indication, something we've alluded to and spoken about before publicly, which is that we're actively assessing additional indications. I think as we look at the landscape -- in psychiatry, and really look at the promise of this drug class and the kind of magnitude that we believe we can achieve in terms of really changing the direction of what we've talked about a lot is the academic of brain health and mental health in this country.

Depression anxiety has such a strong overlap in interplay and looking at a major depressive disorder and other related indications makes quite a bit of sense, of course, as we think about how getting the drug in the hands of clinicians and making sure it has the opportunity for the broadest impact and broadest uptake.

So we'll provide guidance at the right point in time if and when we come to a determination on the exact indication and in clinical development for any subsequent clinical indications, [indiscernible] obviously with the [indiscernible] scores, it would be -- it's hard to overlook at the magnitude of response we've done the potential antidepressant effect in our Phase II study building that on top of a prior study from our colleagues showing a 16-week durable effect in major depressive disorder.

There's obviously we think an opportunity there and something that we'll be looking at very closely and giving further guidance on the future.

[Operator]

Our next question comes from Charles Duncan from Cantor.

[Elaine S. Kim, analyst]

This is Elaine on for Charles. Just going back to your presentation at APA. I'm just curious what feedback do you receive for the KOLs, was the [indiscernible] durability the most important? And also what was the perception towards the improvement in matters? And I have a follow-up on 402.

[Robert Barrow, executive]

Now I'll turn it over to Dan to address that one as well.

[Daniel Karlin, executive]

Yes. Thanks, Elaine. We get feedback of all different types and certainly different folks are focused on different aspects of the efficacy. I think for clinicians who are on the ground treating people with GAD, the rapidity of effect so the fact that we saw strong clinically significant and statistically significant changes on scales that are measurable as soon as day 2 was particularly notable. And then, of course, the durability, as you suggested, there are folks who look at this and take those 2 in combination is say, it really does look like we are eliciting a rapid and durable drug effect, which is unlike other tools that folks have available to them. So across the board, very warmly received and folks are appropriately excited to see these data?

[Elaine S. Kim, analyst]

And for 402, pending favorable PK profile and tolerability from the Phase I trial, what do you envision 402 target product profile to be for ADHD.

[Robert Barrow, executive]

Yes. At a high level, certainly, with no approved therapies to treat core symptoms, [indiscernible] the ultimate goal here is to have a regularly administered treatment that would aid in the [indiscernible] communication deficits in autism.

The analogy we like to draw often is the equivalent of [indiscernible] are used to treat ADHD. Such that while the drug is having a [ tonicological ] effects, with [indiscernible], patients are implemented to better focus and have better participate in [indiscernible]. And the same would apply through different mechanisms and targeting a different disorder, but in [indiscernible] not the social communication deficits, the core of [ autism ] that the FDA patient workshops have described as the target for pharmacological intervention in autism or social communication deficit, the very things that R(-)-MDMA and we believe potentially RDMA will aid in as well.

So the ultimate product profile would be a regularly administered product that would aid in individuals social communication abilities and will allow them to more really participate in their daily occupation.

[Operator]

Our next question comes from Frank Brisebois.

[Unknown Analyst]

This is Dan on for Frank. Firstly, with regard to the planned Phase III, could you give us some color on how you're thinking about the design of that study? Any similarities or differences to the Phase IIb? And specifically, does the Zydis ODT formulations PK impact the Phase III design anyway?

[Robert Barrow, executive]

Yes. So in terms of plan Phase III studies we're going to reserve sort of final determination of the protocols until we have our end Phase II meeting and reached a complete alignment with the agency on the path forward to those pivotal studies. But given our interactions to date, we certainly feel we have a high degree of understanding of the right approach there. And by and large, that the Phase III clinical trials will be extremely similar, if not virtually identical to our Phase II clinical trial design with the exception that we intend to go forward with -- for purposes of the statistical comparison of the overall design comparing 100-microgram ODTs, as you mentioned, to a placebo.

The ODT formulation in and of itself has no impact on the design of the Phase III program. We were really encouraged by the PK bridging results and from what we've seen in that study, both quantitatively and the results we report but also qualitatively and report talking to the investigators in that Phase I study, but believe that certainly going forward the 100-microgram dose is optimal in our view. And we're particularly encouraged about the prospects as we go into that clinical trial. So really no impact in terms of study design, but even higher conviction about the clinical potential of that formulation.

[Unknown Analyst]

That's helpful. Just one quick one. The new epidemiological data that was presented at APA, could you talk about the GAD 7 screening tool, how that's potentially -- if that's being used in the next trials? And any learnings regarding the market opportunity in GAD based on that new data?

[Robert Barrow, executive]

Yes. I'll mention it first and then turn it back over to Dan to talk perhaps about clinical utility of that once again. We certainly are going to be using the GAD 7 and the open-label portion of our Phase III program to screen patients for potential retreatment. So after our 12-week double-blind period, patients will have the opportunity to roll it over into a 9-month open label study where there'll be screened, and then if symptoms of GAD are present then we have the opportunity for retreatment.

I think one of the things we've observed in all the epidemiological data and the disease burden and our pharmacoeconomic research is that one of the most costly patient populations are patients who have GAD symptoms but haven't yet received a diagnosis of GAD. And also patients who have received diagnosis with GAD and have severe disease. As it turns out, the vast majority of patients with GAD have moderate to severe disease in part because the treatments we have available today are not particularly well suited to treating anxiety.

But certainly, we'll be looking at [indiscernible] in our Phase III program. And given the underdiagnosis of GAD, we believe the both the tool will become an important tool in the toolbox of finding these patients out in the real world. Also there's a really massive opportunity that's been underappreciated by payers, like providers and certainly by patients who go many years without a diagnosis and that USP STF's recommendation for using GAD 7 for screening going forward. Really, all of this provides kind of a tailwind for what we expect to be the pickup of the overall prevalence of GAD and ultimately a larger population of patients, we hope to be able to help.

Dan, I'll turn it over to you if you have anything to add on the clinical utility of the [indiscernible]

[Daniel Karlin, executive]

Yes. So I mean what we learned from this epidemiological work was that as we assumed this is an underdiagnosed condition. So despite its high diagnosed prevalence in this particular study, just over 23% of respondents had a positive screen on the GAD 7 and just over 80% of those folks have a diagnosis, had never been diagnosed with GAD. We learned a bit about the health care utilization of these folks who are walking around likely GAD but with undiagnosed GAD. And obviously, there's a tremendous impact on individual well-being, individual distress, but also on health care costs and cost to employers as well.

What all this adds up to is that it's further evidence in support of the [ USPSTF ] recommendations from the past year that folks really ought to be screened. So GAD 7 the is the equivalent essentially for anxiety disorders of the PHQ-9 for depressive disorders. PHQ-9 has been used more and more frequently over the past 30 years to 25-ish years to pick up depressive disorders, some to be expensive anxiety disorders. And so we are strongly supportive of screening for and disorders in primary care settings and other health care settings.

And what ends up being reflected in the data about the current environment is that folks who weren't diagnosed tend to be younger. So that in the end, what is likely happening is that people developing anxiety symptoms in their 20s or early 30s and then go 10, 15, 20 years walking around even distressed without getting a diagnosis and as a result of not being diagnosed, not being able to be treated. And so we continue to believe that people benefit from our [indiscernible] screening and intervention that gets to the disorder and gets to treatment earlier in the course of illness before comorbidities and other impacts of the illness accumulate?

[Operator]

[Operator Instructions] Our next question comes from Sumant Kulkarni from Canaccord Genuity LLC.

[Sumant Kulkarni, analyst]

So what are your latest thoughts on potentially developing MM-120 for depression? And would that be a program that the organization is ready to run simultaneously with the pivotal program in GAD and other things you're doing on 402. Or are you focusing on GAD with undivided attention until you get more clarity on trial results there?

[Robert Barrow, executive]

Yes. Thanks so much, Sumant. Yes. No. As I mentioned earlier, we certainly are taking a very hard look at the market dynamics and the opportunity and depression and related indications. We have built the company really from the ground up over the past 3 years and have done so all along the way with the ability to -- with I, of course, to executing on technical development programs, but also with the ability to take on multiple programs far beyond what's currently in our pipeline. So the infrastructure and our team and our ability to execute operationalized multiple programs in the pipeline has been something that we've been working towards and have been doing over the past several years. And so we certainly believe and expect that we'll be in a position to execute on multiple clinical indications potentially in parallel.

We never lose focus on our furthest along asset, the furthest long program, which is, of course, MM-120 in GAD. But even as we've conceived of operationalizing other indications like for instance, potentially in depression, there are many operational efficiencies and quite a bit of overlap. So we'll be in a position to give further guidance and we decided to launch a program in a second indication with 120. But based on our team's abilities and based on certainly the existing evidence believe there's opportunity in depression and a number of other indications in brain health.

[Sumant Kulkarni, analyst]

Got it. And as a follow-up, as you plan to hold your end of Phase II meeting with the FDA, where do you think the most potential for differences between what you might propose versus the FDA's potential outlook might be?

[Robert Barrow, executive]

I wouldn't want to speak for the agents. We obviously try to go into any sort of regulatory interaction. And we very much have appreciated and it's easily said, but it's very much true and I've had the privilege of working with the agency in this division on the drug class in the past five or so years. And we know they've been extremely thoughtful, extremely productive and there's always nuances in a drug development program. But we certainly listen to the conversation with the dialogue we've had in the past and follow the guidance and try to make logical rational scientific arguments for when there's any sort of particular view that needs to be discussed or hashed out.

So I'd be reluctant to speak for FDA and say where we would expect there to be some particular points of discussion. But by and large, I think we view FDA as very much as a partner in this and have had a very constructive dialogue date and expect that to continue as going into Phase II.

[Operator]

Our next question comes from Elemer Piros from Rodman.

[Elemer Piros, analyst]

Rob, I'd like to talk a little bit about -- if you wouldn't mind addressing how heavily pretreated, the Phase IIb population was. And in the commercial setting once we get there, where do you see MM-120 being used, especially considering that there is a large population that is undiagnosed without treatment. Where would MM-120 fit in based on your Phase IIb trial, your Phase III design once you agree with the FDA, et cetera.

[Robert Barrow, executive]

So I'll take the second part of the question first, which is to say when we conceive of where MM-120 could fit in the real world in clinical practice, I think as a field, there's been some of a constraining of views on the opportunity in a concept that these therapies could only be reserved for the most severe patients who have failed everything else.

And what we're really seeing over and over in the clinical data is that there seems to be a sort of trajectory change. And so in GAD in particular, what we observe is that patients who go undiagnosed and/or have severe GAD end up -- you're spending years going to the doctor having the related comorbidities and they have a huge impact on their quality of life and also a huge impact on the health care system.

Now where the value also comes from we talked about reimbursement. We talked about the burden on the health care system from a financial point of view are in those patients to go undiagnosed who has severe GAD to walk around not knowing that they have severe GAD. And so we actually see the opportunity is far more expansive than simply the patients who have failed everything out.

Now that is not to say that we expect and we're going to be marketing as a first-line therapy per se. We obviously are going to be focused in our commercial activities and certainly believe there is enormous value to be gained by focusing on the patients who had severe prior treatments and who have severe disease. But we certainly believe there's a likelihood that patients who are not at the end of their treatment course and [indiscernible] everything else could potentially benefit. And that really also aligns with the data we've been able to generate.

Now we see a nice mix that is largely representative of the real-world population in our clinical trial. So certainly, a significant portion of the patients have prior treatments and have scaled numerous prior treatments. When we look at slices of the data, we don't see a meaningful difference between response regardless of treatment history, which, again, I think in depression, there's much better definition of treatment resistance and focus on a last line patients, but in GAD it's somewhat of a different dynamic that we think is more favorable, both from a business standpoint and from a clinical impact standpoint.

[Elemer Piros, analyst]

Yes. And do you think that there is a difference between the journey of a patient newly diagnosed, then try different sort of medications in -- with primary diagnosis is depression as opposed to GAD. [indiscernible] what sort of physicians one versus the other would see before they get some significant help if ever?

[Robert Barrow, executive]

I'll turn over to Dan to maybe address initially and happy to extend on that, Dan?

[Daniel Karlin, executive]

Yes. Happy to try to address. And I think it's a really good question about the patient journey. I think what we have to remember when we think about the differences between MDD and GAD is that while they are very much overlapping diagnosis, MDD is episodic. It's a cyclical illness with periods of depression in spurs with periods of view time [indiscernible] normal mood. And so folks falling into a state change going from their sort of usual state into a depressed state, maybe more likely to seek care earlier in the course of the illness. And what we're seeing as we dive deeper and deeper into the epidemiology of anxiety disorders in GAD is that the insidious nature of the onset of GAD may lead folks to be seeking care later to sort of to acclimate to this new way of feeling and even though they're in distress, not necessarily see it as a target that they would want to raise with a clinician.

With both of these conditions, the patient journey very often starts with primary care. Their folks have more contact with their primary care doctors if they're not regularly seeing a psychiatrist rather psychiatry provider. And often, first-line treatments are given at the level of primary care, again, partly due availability of specialty psychiatric providers who can prescribe. So things like SRIs, as a starting point, have moved toward primary care for both depression and anxiety or depressive and anxiety disorders. As folks show themselves to either be more severe or to be more resistant treatment to not sustain benefit or to have intolerable side effects with first-line treatment is generally when folks enter the psychiatric care system.

But we know is that these patterns are driven by treatment availability. It was the commonality that the frequent prescribing, the familiarity with SRIs that brought them into the primary care setting in a way that previous antidepressants maybe weren't as comfortable for primary care doctors, MAOIs and things like [ Tricyclics ], which are more difficult to prescribe.

And so while we can reflect on the current patterns of care, journeys of care where people are getting what sorts of care. The availability of different treatments changes those patterns. And so while we absolutely think about how things happen today, we are also very much ornate toward creating a world that is built to an extent around what we're able to bring to bear on these disorders.

Then just a little follow-up here, if you don't mind. So some people believe that a psychedelic medicine treatment would only be prescribed by a specialist. I'm not sure because after all, whether you're a general practitioner or specialist, you're not going to administer these therapies. They are going to be administered at specialized centers. So you're not going to be necessarily directly involved in the actual treatment. Do you agree or disagree this line of thought?

[Daniel Karlin, executive]

I think there are parts of that, that we absolutely agree. Within other parts, we might push back on a bit. So the sorts of prescribers who are comfortable prescribing any given medication will have everything to do the sorts of data we're able to generate around efficacy and safety in appropriate patient populations, appropriate assessments for pre-prescribing. And that in many cases, perhaps the prescriber -- the prescribing health care provider will be affiliated with or possibly even involved with the actual administration of medicine possibly with the help of lower level providers.

There are many cases we can imagine, were the prescriber and the ultimate session monitor may not even be affiliated with one another that they be identified individually. And that while what we've seen for interventional psychiatry today is largely centered around specialized centers. This has to do as much with the need for physiological monitoring and medical certification as with actual safety and appropriateness of location.

We didn't see physiological liability in Phase IIb, which we believe will begin to open up the possibility that we can build the body of evidence that the types of places where MM-120 can be safely administered might be significantly broader than specialized centers.

So very much considering a range of options for who could be the potential prescribers and who could be the potential session monitors.

[Robert Barrow, executive]

I'll just again -- I'm going to add one comment on top of that, Elemer, which is that I think one of the things we repeatedly want to make sure is fully appreciated is the scale of the potential opportunity here and the fact that just because treatment practices today with the tools and the toolbox of practitioners, right?

When we live in a world, we're only SRIs primarily are administered and then they're often doled out first at primary care. It's easy for observers of that market to start to say, well, that's the only way it can be done. And really, what we're talking about is a sort of transformational change, both at a patient level because of the magnitude and the durability of response we're able to generate, but also at a level of medical practice where we can actually start to think about having these new tools really reshape the ability to have meaningful impact on patients. And so doing opening up the potential opportunity such that this isn't relegated to a very last line of treatment where no one can access it because they have to go on to a psychiatrist for 5 years before they're eligible.

We see that as too constrained of a view here and believe that there's a need for a much larger opportunity or need for a much larger view of how we can have a meaningful impact.

[Elemer Piros, analyst]

Yes. May I just add one other aspect. And I'm sure that a specialist, a psychiatrist spent a lot of time to manage the side effects or managed titrating those drugs or replacing with another one? We don't have this issue with MM-120, do we?

[Daniel Karlin, executive]

That's exactly right.

[Robert Barrow, executive]

I'll say -- I mean, obviously, Dan is a practicing psychiatrist. That said, when we talk to [indiscernible] one of the things that we hear over and over again is the excitement around a drug with a high degree in relative terms of clinical remission that we're able to achieve. And the fact that those results are driven by both the rapidity and durability of effect, such that patient walks in the door with SRI, as you mentioned, Elemer, patient is going to be given the drug and it's going to take a number of weeks before there's an expected clinical benefit. Now over that time is when we see the adverse events, the side effects of the drug already occurring.

Here, what we're seeing is such a rapid response that a follow-up within a couple of days is largely indicative of where the patient at least in our study so far, is going to be months later in large part, if they achieve remission, they seem to stay in remission. And so that kind of clinical clarity early in the treatment course is something that is high desirability from providers and something that we are very excited to see in our data.

[Elemer Piros, analyst]

Yes. But you forgot to mention the headache, the next morning.

[Robert Barrow, executive]

Well, there's lots of things that are worse for you that give you headaches the next morning. So we feel very comfortable with the physiological profile.

Next question comes from Patrick Trucchio from H.C. Wainwright & Company.

[Patrick Trucchio, analyst]

I have a couple of follow-up questions. The first is on the new epidemiological data presented at APA. Just in terms of the potential impact on commercialization of MM-120 in GAD. I'm wondering if you can talk about the prospects or possibility of having this validated GAD 7 screening tool more widely deployed in the real-world health care setting as part of this potential commercialization?

Secondly, if this data itself is helpful or can be built upon as part of health economic outcomes research? Or is there some other use for it that could be beneficial for the potential launch of MM-120?

And then separately, just there's some UHB data upcoming. So I was wondering, first, if you can give us an idea of potential read-through regarding durability of treatment we should expect from the Phase II UHB data being presented cytibiological psychiatry and whether or not findings in that study could impact discussions with the FDA regarding the MM-120 Phase III program and what way could that data maybe be helpful to you?

And then separately, regarding MM-402, can you talk about the potential read-through from the UHP Phase I trial to your program and how you think about next steps for MM-402 and ASD assuming a positive outcome from your SaMD study.

[Robert Barrow, executive]

Yes. I'll try to take these one by one. So certainly, in terms of the prevalence, although we've been talking about the underdiagnosis of GAD, the fact that there is a tool that can, we believe, validly pick up GAD is yet to be diagnosed. The fact that, that is now being recommended for implementation and has not been fully implemented, suggests to us that really what we're seeing in terms of current epidemiological data is just the tip of the iceberg. The market is actually much, much larger than we're seeing in the statistics today or in the last several years. So that obviously has a huge impact from a health and societal level.

But from a market opportunity, of course, it means that the market may be -- or does the magnitude margin that we're expecting based on current optenological data. And that aligns with certainly what we hear and hear from clinical practitioners that we absolutely actively are working on [indiscernible] health economics research to quantify the scale and the scope of the impact that we can ultimately see here. And to demonstrate the value proposition to all of the key stakeholders who are going to need to be aligned to enable the broad uptake of our products. So something we are actively engaged and have a really talented group that is working on that.

Potential read-through of the UHP study. Certainly, as we look back over the past couple of years, we initially had -- [indiscernible] data on lysergide, different dose and regimen, but that demonstrated the durable effects out to really about 6 months after treatment for the patients who got LSD or lysergide first. And in this study, we now have a follow-up even further with those patients.

So as we've conceived the Phase II results that we were able to achieve, we've also seen -- largely in terms of HAM-A scores, a sort of flat lining where we didn't see a regression back to baseline or worsening of symptoms on average over time. And so if we ultimately are seeing those effects granted investing in initiated smaller studies, but these are effects that are shown to be durable for many months longer. I think one [indiscernible] I think it bodes well for the potential of what we'll be able to demonstrate as we go forward into longer something like open-label study that's planned for Phase III.

And similarly, within MM-402, of course, it's very difficult to have read through from a healthy volunteer population into a disordered population in terms of results from a Phase I study. But certainly, the understanding we'll have in terms of the -- some of the mechanisms underlying the activity of MM-402, the demonstration of tolerability and sort of [indiscernible] profile that we'll be able to report out and observe with within the [ 42 ] of the doses of 250 milligrams will be certainly encouraging for us and won't be informative as we continue to design our program. But again, it's hard to -- we don't want to overextend the interpretation of healthy volunteer data when we talked about going into Phase II and later research.

Thank you. I am showing no further questions at this time. That does conclude our question-and-answer session. Thank you for your participation in today's conference. This does conclude our program. You may now disconnect.
