Speaker #2: This conference call contains time-sensitive information and is accurate only as of live broadcast, November 12th, 2025. With that, I'll turn the call over to Sean.
Speaker #3: Thanks, Alex. Good afternoon, everyone. Thank you for joining us for our Q3 business update call. Today, we'll be sharing updates about our pipeline, including interim phase one results for ABS 101, acceleration of ABS 201 development in Angiosynthetic Alopecia or AGA, and expansion of ABS 201 development in a second indication, endometriosis.
Speaker #3: Interim results from first cohorts of our ongoing ABS 101 phase one trial in Healthy Volunteers demonstrated extended half-life as compared to first-generation anti-Tier 1A competitor programs but not versus next-generation programs.
Speaker #3: There was also no apparent impact of ADA on PK and overall safety profile was favorable with no serious adverse events reported to date; the phase one trial is on track to complete in Q1 of 2026.
Speaker #3: Our progress developing ABS-201 for angiosynthetic alopecia is ahead of plan, as we expect to initiate a Phase 1/2A trial in December of this year, with an interim proof-of-concept readout anticipated in the second half of 2026.
Speaker #3: Additionally, we are excited to announce that we are developing ABS 201 in endometriosis and expect to initiate a phase two proof of concept clinical trial in the fourth quarter of 2026.
Speaker #3: Preclinical and clinical data support the prolactin receptor mechanism in endometriosis where we believe ABS 201 has the potential to be a safe effective therapy for the estimated 10% of women globally who suffer from this debilitating disease.
Speaker #3: Our development plans for endometriosis are synergistic with our already planned ABS 201 phase one 2A clinical trial in AGA, which is on track to initiate next month.
Speaker #3: Given the significantly greater opportunity for value creation, we have made the strategic decision to prioritize ABS 201 development in endometriosis. This is in addition to ABS 201's ongoing clinical development for Angiosynthetic Alopecia.
Speaker #3: Therefore, we will seek a partner for ABS 101 and no longer pursue additional internal clinical development for this asset following the completion of the phase one clinical trial.
Speaker #3: The decision to reallocate our pipeline priorities reflects rigorous discipline we employ in allocating our capital and resources. We believe our strategy to advance ABS 201 through human proof of concept in both AGA and endometriosis will maximize the value created using our current balance sheet.
Speaker #3: Both indications are characterized by significant unmet medical need and poor standard of care. There is biological and clinical rationale for the prolactin receptor mechanism in both indications.
Speaker #3: Our strategy leverages shared phase one development, which enables faster, more efficient clinical trial development, and both indications offer multi-billion dollar market opportunities. Looking ahead, we're excited to execute on the dual development of ABS 201, leveraging its best-in-class profile targeting two proof of concept readouts in the next 24 months.
Speaker #3: A phase one 2A proof of concept interim data readout in AGA in the second half of 2026 and a phase two proof of concept interim data readout for endometriosis in the second half of 2027.
Speaker #3: Taken together, this strategy represents our strongest value creation opportunity for patients and shareholders alike. Zachariah Jonasson will speak in more detail on our strategy for endometriosis later in the call.
Speaker #3: Turning now to our clinical development plans for ABS 201 in Angiosynthetic Alopecia. We have accelerated our clinical development timeline and expected dose of first participant next month in our phase one 2A study.
Speaker #3: On December 11th, we'll host a KOL seminar to discuss anticipated clinical development path, market opportunity, and differentiated profile of the ABS 201 program. We also plan to disclose additional human ex vivo data that further supports the mechanism of action underlying this program.
Speaker #3: We designed ABS 201 to unlock the potential new category of therapy for AGA, which we believe could offer efficacious, durable, convenient hair regrowth. This condition, better known as male and female pattern hair loss, affects approximately 80 million adults in the US alone and has seen little therapeutic innovation in nearly 30 years.
Speaker #3: In preclinical studies, ABS 201 has shown high potency, low immunogenicity, extended half-life, and improved manufacturability. We believe it offers an alternative to current treatments such as minoxidil and finasteride, which have variable or limited efficacy, low compliance, and in some cases, serious side effects.
Speaker #3: Based on the body of evidence from in vitro and in vivo animal studies, we believe that a simple infrequent course of just two to three injections of ABS 201 could deliver durable multi-year hair regrowth.
Speaker #3: Today's standard of care treatments have limited efficacy and require frequent once or twice daily administration leading to poor compliance. Our KOL network of leading dermatologists has indicated compliance for topical as well as oral minoxidil can be poor in practice.
Speaker #3: Either because of side effects or inconvenience of lifelong daily administration. A recent study showed that over 86% of AGA patients who try topical minoxidil discontinue treatment.
Speaker #3: Our own market research underscores that consumers value durable efficacy and prefer a treatment that works with infrequent administration. For these reasons, we believe ABS 201 has the potential to be a dominant new category of therapy offering convenient, durable hair regrowth.
Speaker #3: Given this differentiated profile, the straightforward clinical development path, and the massive multi-billion dollar market opportunity, we plan to develop ABS 201 through later stage clinical development and potentially commercialization.
Speaker #3: As we advance development of ABS 201 for AGA, we're thrilled to welcome Dr. Rod Sinclair and David Goldberg to our KOL advisory board. Dr. Sinclair is a professor of dermatology at the University of Melbourne and the director of Sinclair Dermatology.
Speaker #3: He is a world-renowned expert in hair loss, with over three decades dedicated to research, clinical practice, and patient advocacy. He has more than 1,000 publications, including contributions to major dermatology textbooks.
Speaker #3: Dr. Goldberg brings nearly 40 years of clinical dermatology experience. He is a clinical professor of dermatology at the Icahn School of Medicine at Mount Sinai.
Speaker #3: And has led pivotal research studies in dermatology and hair loss, including the original minoxidil trials. Dr. Goldberg has published more than 200 academic papers contributed to over 15 textbooks on hair restoration and dermatology, and served on the boards of the American Academy of Dermatology and American Society of Dermatologic Surgery.
Speaker #3: We invite you to join our virtual seminar on December 11th, where Dr. Sinclair, Dr. Goldberg, and other top KOLs will discuss the ABS 201 program.
Speaker #3: We are also progressing several additional programs, that we aim to partner prior to clinical development. ABS 301, this is a potential first-in-class antibody targeting undisclosed immuno-oncology target identified through a reverse immunology platform.
Speaker #3: Early data suggests potential in squamous cell carcinoma and other indications. ABS 501, this is a potential best-in-class anti-HER2 antibody identified using our zero-shot de novo AI models.
Speaker #3: These AI-designed leads displayed novel epitope interactions, increased or equivalent potency to trastuzumab in preclinical disease models, efficacy against a trastuzumab-resistant xenograft tumor in an in vivo model, and good developability.
Speaker #3: Beyond these, we have innovative early-stage programs in our pipeline that we plan to reveal at a later date. With that, I'll now turn the call over to Zach to walk through our strategy partnerships and outlook and to provide an update on our financials.
Speaker #2: Thanks, Sean. As Sean mentioned, we continue to sharpen our strategic focus. And in so doing, have made decisions recently about which internal programs to advance versus partner.
Speaker #2: Our decisions continue to be based on careful assessment of the potential risks and return for each program given our available resources. Broadly, I am happy to report that we continue to execute on our strategic objectives.
Speaker #2: Including advancing ABS 101 through an interim Phase 1 readout and expediting the initiation of our ABS 201 Phase 1 2A trial for androgenetic alopecia by approximately one quarter.
Speaker #2: Expanding ABS 201 development into endometriosis. And progressing our portfolio of discovery partnership programs. We also continue to expand our AI platform capabilities. Which, in addition to enabling our own preclinical R&D programs, focused on challenging targets, has helped generate partnership interest in our platform.
Speaker #2: Accordingly, we continue to anticipate signing one or more drug creation partnerships including with a large pharma company by year-end. As Sean discussed earlier, we will be focused on partnering ABS 101 and do not currently plan to develop the program ourselves into phase two.
Speaker #2: We remain engaged with multiple potential large and mid-cap pharmaceutical companies regarding a potential partnership transaction. Some of which are focused on first-in-class indications outside of IBD.
Speaker #2: As discussed, we have decided to prioritize the clinical development of ABS 201 for two potential multi-billion dollar indications: androgenetic alopecia and endometriosis, each characterized by high unmet need and poor standard of care.
Speaker #2: We see strong scientific and business rationale for developing ABS 201 in both of these indications. Moreover, our planned phase one 2A clinical trial in AGA will provide safety, tolerability, and PK assessments that will support phase two clinical development in endometriosis.
Speaker #2: The Phase One 2A proof-of-concept trial in AGA will be a randomized, double-blind, placebo-controlled study. The primary endpoints will be safety and tolerability; secondary endpoints will include PK, PD, immunogenicity, target area hair count, target area width, target area darkening and pigmentation of hair, as well as patient-reported outcome measures.
Speaker #2: The trial will enroll up to 227 healthy volunteers with or without AGA. The single ascending dose or SAD portion of the trial will test approximately four to six IV dose groups for safety, tolerability, PK, and PD.
Speaker #2: The SAD portion of the trial will be followed by approximately three to four subcutaneous multiple ascending dose groups in healthy volunteers with androgenetic alopecia.
Speaker #2: The MAD portion of this clinical trial is powered to demonstrate human proof of concept for the use of ABS 201 to treat androgenetic alopecia by stimulating significant hair regrowth.
Speaker #2: We believe that this trial is successful, will position the program for accelerated registrational ational trials. Ahead of initiating the phase one 2A trial, we are excited to share that we have generated additional ex vivo human data supporting the durable condition-modifying hair regrowth mechanism of ABS 201.
Speaker #2: Preliminary data from experiments using human scalp biopsies shows the ability of ABS 201 to transition hair follicles into the antigen growth phase and to counteract suppressive catagen effects of prolactin.
Speaker #2: This study also shows ABS 201's ability to promote the proliferation of hair follicle stem cells as indicated by upregulation of corresponding markers. As well as reduce hair follicle stem cell apoptosis.
Speaker #2: We look forward to sharing more about this study and its results at our upcoming KOL seminar on December 11th. As Sean mentioned earlier, in addition to treating androgenetic alopecia, we believe ABS 201 will be effective in treating endometriosis.
Speaker #2: A second multi-billion dollar market opportunity characterized by high unmet patient need and poor standard of care. Endometriosis is an inflammatory disease defined by endometrial-like lesions found outside the uterine lining.
Speaker #2: Symptoms include pelvic pain, heavy bleeding, infertility, and ovarian cysts. It is a chronic painful condition that significantly impacts the quality of life of these patients.
Speaker #2: Moreover, there is currently no therapeutic or surgical cure for this disease, which is prevalent in an estimated 10% of women worldwide, including an estimated 9 million women in the US alone.
Speaker #2: During our R&D day last year, we discussed how members of our R&D team initially discovered the prolactin receptor inhibition mechanism for hair regrowth during animal studies investigating prolactin inhibition as a treatment for endometriosis.
Speaker #2: Based on additional preclinical research, including our own in vivo animal studies, as well as recent human clinical proof of concept data reported for the HMI 115 program, we believe ABS 201 has significant potential to become a best-in-class, efficacious, and safe therapeutic treatment for endometriosis.
Speaker #2: ABS 201 was designed using our AI platform to antagonize the prolactin receptor and thereby block prolactin signaling. Scientific data support the dual role of prolactin signaling in endometrial lesion formation as well as associated pain.
Speaker #2: Prolactin and prolactin receptors are overexpressed in the endometrium of patients with endometriosis. Furthermore, while prolactin supports endometrium formation in decidualization, dysregulated expression of prolactin and its receptor has been found in ectopic endometrial lesions.
Speaker #2: Prolactin receptors are also present in sensory neurons and can sensitize these neurons, potentially leading to increased pain perception. The prolactin pathway is distinct from sex hormone signaling, further differentiating it from current therapeutic mechanisms of action for treating endometriosis.
Speaker #2: Preclinical data have shown that prolactin receptor antagonism suppresses post-operative pain in female mice and inhibits endometriosis internal formation. A recent preclinical study in a homologous mouse model of endometriosis shows that ABS201 treatment improves pain-related outcomes, similarly to GnRH modulation.
Speaker #2: Mice treated with ABS 201 demonstrated greater locomotor activity and distance traveled as compared to placebo-treated mice. Indicating reduced pain-like behavior, ABS 201 also significantly lowered inflammatory cytokines in the peritoneal fluid, which have been shown to be elevated in endometriosis patients.
Speaker #2: These results support our development of ABS-201 as a potential therapy for endometriosis-associated pain. Additionally, recent positive top-line results from a Phase 2 trial of HMI-115, a competitor anti-prolactin receptor antibody, in endometriosis provided human proof of concept and de-risking of the mechanism of action.
Speaker #2: We believe that ABS 201's profile exhibits best-in-class potential when compared to the HMI 115 antibody. For example, ABS 201 exhibits superior PK and bioavailability, and NHP studies which we expect to translate to better efficacy in humans via sustained target engagement in relevant endometrial tissue.
Speaker #2: ABS 201 also has three to four X longer half-life in NHPs as well as a higher concentration formulation, both of which should enable more convenient dosing for patients.
Speaker #2: We plan to initiate phase two clinical development of ABS 201 in endometriosis in Q4 of 2026 using the safety and tolerability data generated from the SAD portion of our phase one 2A androgenetic alopecia study.
Speaker #2: Based on this timeline, we expect to share an interim readout from the phase two trial in endometriosis in the second half of 2027. With respect to ABS 301 and ABS 501, our immuno-oncology and oncology programs respectively, we continue to believe that these programs are better suited for development by a large pharmaceutical or biotech company.
Speaker #2: Accordingly, we intend to seek partners for these programs prior to clinical development. We continue to utilize our growing AI platform capabilities to create an early-stage pipeline focused on indications characterized by high unmet medical needs.
Speaker #2: Our unique ability to address difficult-to-drug target classes has enabled us to pursue new opportunities for creating novel and differentiated therapeutic programs in our internal pipeline as well as in our drug creation partnerships.
Speaker #2: Turning now to our financials, revenue in the third quarter was $400,000 as we continue to progress our partnered programs. Research and development expenses were $19.2 million for the three months ended September 30, 2025, as compared to $18 million for the prior year period.
Speaker #2: This increase was primarily driven by advancement of appetite internal programs including direct costs associated with external preclinical and clinical development. Selling general and administrative expenses were $8.4 million for the three months ended September 30, 2025, as compared to $9.3 million for the prior year period.
Speaker #2: This decrease was primarily due to a decrease in personnel-related expenses. Cash, cash equivalents, and marketable securities as of September 30, 2025, were $152.5 million compared to $117.5 million as of June 30, 2025.
Speaker #2: We believe our existing cash, cash equivalents, and short-term investments will be sufficient to fund our operations into the first half of 2028. We see additional upside to this forecast based on potential non-dilutive cash inflows that could come from new platform collaborations with large pharma and/or an asset transaction associated with any of our wholly owned programs such as ABS 101.
Speaker #2: As a reminder, we still anticipate signing one or more drug creation partnerships including with a large pharma company before the end of this year.
Speaker #2: With our current balance sheet, we believe we are well positioned to execute on our strategy, including delivering potential proof of concept readouts for ABS 201 in both AGA and endometriosis.
Speaker #2: We are also resourced to progress our early-stage pipeline and to advance new partnership discussions related to our AI drug creation platform, wholly owned asset programs, or both.
Speaker #2: With that, I'll now turn it back to Sean. Thanks, Zach. I want to thank our appetite team for their relentless drive, tenacity, and belief in our mission to achieve the impossible.
Speaker #2: This is a pivotal moment for appetite. As you heard today, ABS 201 is moving into the clinic with real momentum and we're expanding its potential beyond hair regrowth into endometriosis.
Speaker #2: A major disease area where innovation is long overdue. Together, these efforts underscore the potential of the prolactin receptor mechanism and demonstrate our commitment to translating generative AI protein design into clinical realities.
Speaker #2: We've made deliberate choices to focus our resources where we see the greatest opportunity for transformational impact and value creation. By refining our focus on ABS 201, we're leaning into the data, the science, and the market opportunity where appetite can lead.
Speaker #2: Looking ahead, the momentum is unmistakable. The ABS 201 phase one 2A trial in AGA begins in just a few weeks. Putting us on track for interim efficacy and proof of concept data in the second half of next year.
Speaker #2: We are expanding ABS 201 into endometriosis with a phase two trial anticipated to initiate Q4, 2026. We anticipate to close at least one new large pharma partnership this year and I invite you to join our ABS 201 KOL event on December 11th.
Speaker #2: Details are on our IR website. Appetite is executing with precision and agility, translating AI design biologics into real clinical impact. What truly excites me is the potential ahead.
Speaker #2: We are energized by what's next and confident in our path to deliver meaningful value for patients, partners, and shareholders alike. Thank you for your continued support.
Speaker #2: Operator, let's open the call for
Speaker #2: questions. At this time, I would
Speaker #3: like to remind everyone in order to ask a question, press star, then the number one in your telephone keypad. We will pause for just a moment to complete compile the Q&A roster.
Speaker #3: Your first question comes from the line of Emil Devan. With
Speaker #1: I could Move . one I understand what you're saying around the tl1 program and looking to partner that out . I'm wondering if you just .
Speaker #1: Is there any more details you can share just in terms of what you saw , in terms of the half life or anything else in the trial ?
Speaker #1: And then second , I'm just the endometriosis . It's interesting news there . So looking forward to seeing , hearing and learning more about that .
Speaker #1: But I'm just curious right now if you could maybe just give some sense of the competitive landscape as you're thinking about designing a phase two trial in that , in that indication or how that would look and how generally how you design it and what's the right comparison to think about ?
Speaker #1: Thank you .
Speaker #2: , absolutely . Yeah Thanks . Yeah . So we took a really hard look at ABS 101 . You know , we were you know , in general really happy with the , you know , the safety profile that we saw .
Speaker #2: We were able to to have a half life that was extended past what we saw with first gen competitors . But we fell short of of second gen .
Speaker #2: And we were exploring some I think really exciting . First in class indications , we could have gone into and we compared that to taking ABS 201 into endometriosis and just given the competitive , you know , landscape , we were seeing in IBD , we saw it .
Speaker #2: It made a ton of sense to take the capital . We'd be investing into ABS 101 phase two study and reinvest that into ABS 201 into And we did endometriosis .
Speaker #2: this for for a few reasons . One , there's a big unmet medical need here . The standard of care is is really poor .
Speaker #2: lot of There's not a competition in this space . And additionally , the the mechanism , the prolactin receptor is has been ultimately de-risked HMI 115 data that that came out showing proof of concept for this particular mechanism .
Speaker #2: So we see this as , as a de-risked mechanism . And again , standard of care is , is is pretty poor here .
Speaker #2: And we really believe that we have the opportunity to potentially deliver a disease modifying treatment . There . And with that I'll hand it over to , to talk a little bit more about the phase two trial design for endometriosis .
Speaker #3: Thanks , Yeah . Sean . Just to echo a couple points , Sean made , we don't we see the endometriosis indications much less competitive you see than Crohn's .
Speaker #3: And that certainly was a factor in our decision here . Moreover , the cost of these trials is a fraction of what a full phase two proof of concept study in in the IBD space would be .
Speaker #3: So we think there's a significant ROI on resourcing this strategy for development . And we will talk more about the specific design . trial But I think what we're really excited about here with the ABS 201 mechanism , is that there's a potential not just to address pain , but also to be disease modifying .
Speaker #3: And so we're currently engaged with our Kols and draft study have a design that will share more about in the new year .
Speaker #1: Okay. Thank you.
Speaker #4: Your next question comes from the line of Brendan Smith with TD colon . Please go ahead .
Speaker #1: Hi guys . Thanks for taking the questions . I appreciate I appreciate it . So maybe . just First on actually just the a quick one .
Speaker #1: profile for 101 . And apologies if I missed it here , but can you confirm if any of the potential partners you had been in touch with prior to have already seen the data , or if that's kind of the plan over the next few weeks ?
Speaker #1: wondering And just on initial feedback , now there and then maybe quickly on 201 . I know you've talked a bit about endometriosis versus alopecia , but just there's wondering if ever if there's any , maybe even at a high level .
Speaker #1: Thoughts on market segmentation just given to a one's mechanism . And any considerations on how you're thinking about enrollment for that ? Thanks .
Speaker #2: Yeah . Great . So to address the first question since this data has just recently come in , we have not had the opportunity to share this data with with our partners .
Speaker #2: Yet . We to share that with them in the coming weeks . And then additionally , as I mentioned previously , we have been exploring other first in class indications that we believe they're strong biological rationale for this .
Speaker #2: And it actually expands the the buyer universe ABS for one . For ABS 101 . And we we have been exploring that . You know , to prior to this prior those call and discussions have been going quite well .
Speaker #2: And I'll hand it over to to Zach to answer the second question .
Speaker #3: Yeah . Thanks , We're as I mentioned , Brendan . we'll release more details about the trial design for endometriosis . But I will comment that we will be looking enroll to are patients that confirmed to have endometriosis and that we be looking to enroll patients that have a significant amount of pain .
Speaker #3: And I think that was one of the challenges the study with HMI . 115 . I think they had some enrollment issues around criteria that we exclusion will be careful to address trial .
Speaker #3: And I think we've got some leading in our kols advising us here . So we feel we feel very confident and excited about moving that program forward .
Speaker #3: There's a very large unmet medical need there , and I think a very large opportunity based on what we saw from the HMI trial , that was a nice proof of concept on the .
Speaker #3: As you know , mechanism trial there in the high dose , statistically significant reduction in pain . And so I think and dysmenorrhea that's a readout for us nice de-risking the mechanism and the mechanism also looks safe in that trial setting .
Speaker #3: So we feel very confident about bringing ABS 201 into development for that indication .
Speaker #2: Yeah . And I'd also like to just loop in on Andreas , our chief innovation officer this , into question . He had experience at Bayer , actually developing an antibody which is now HMI 115 for endometriosis .
Speaker #2: so And have anything , Andreas , do you else to add here ?
Speaker #5: Yeah , sure . Thanks , Shah . I think it may be relevant to point out here that the drug innovation around prolactin receptor started around antibodies endometriosis and not hairloss , and the hairloss observation was actually serendipitous .
Speaker #5: Finding at the time . Again , it's it's very clear , very well validated that a dual prolactin has mechanism in endometriosis , both in promoting and generating the lesions as well as in sensory where neurons it clearly affects the pain and the pain sensation in .
Speaker #5: And preclinical experiments , it was nicely shown that prolactin our antibodies in experiments now at Absci , as well as previously in hands , Bayer's that it can indeed affect both pain as well as reducing the lesions as has indicated I also before , want to point out that there is a significant unmet medical need the fact based on that there are not any non-hormonal treatments around in endometriosis .
Speaker #5: There is , of course , the approved GnRH antagonist treatment , which has the typical side effect of estrogen reduction . And there is a significant of non-hormonal safe approaches and need this endometriosis .
Speaker #5: is And what our data of prolactin receptor antibodies so far have shown . High safety , in both experiments preclinical as human genetics , where women with complete of knockout prolactin receptors have been shown to be perfectly healthy and being very easy even , easily to bear able children .
Speaker #5: Sexual .
Speaker #4: next . Operator question . can we line Her
Speaker #4: .
Speaker #2: ?
Speaker #4: Your next question Next the line of Shen Lemmon Stanley . Please with Morgan ahead comes from
Speaker #6: Sean . And hi , team . Hope Oh , everyone's hi , well to gauge . Sean , just on the data that you do being have of able to one on partner one out what are for .
Speaker #6: in a partner
Speaker #2: Yeah , absolutely . It's a great question . So what we're in a partner looking for one the domain expertise
Speaker #2: to go is in
Speaker #2: develop actually that it in indication particular . And ultimately be able to take it through , through approval so your again , I think we have .
Speaker #2: And a much bigger bio buyer universe with the , you know , the different indications that we are looking at here . And , you know , you know , we we are excited to .
Speaker #2: Begin to engage in those discussions . Zach , do you have anything else to to add on the partner in front ?
Speaker #3: I would just add that as Sean mentioned , we have done some work on a first in class indication for ABS . 101 , and we've had some engagement already on that indication .
Speaker #3: We'll be continuing those discussions as we move towards the end of and into early the year next year , but we feel pretty excited about the potential to partner this with asset with a pharma that will be exploring first in class type indications .
Speaker #6: Sure . Thank you . And just on 201 , just to sort of gauge your feeling on on how easy the trial is going to be to recruit .
Speaker #6: I imagine be a fairly facile process , but I could be wrong . And then just maybe sort of the cost to to sort getting it of concept status .
Speaker #6: And how long do you anticipate a patient would need to be on drug to potentially reach the outcome that you're looking for ?
Speaker #2: Great. Thank you. I want to take the first two questions, and then Andreas, I'll hand it over to you for the third.
Speaker #3: Yeah , absolutely . And just to clarify , when you asked the question , are you referring to endometriosis or Aga ?
Speaker #6: Sorry , alopecia . Sorry .
Speaker #3: Yeah . Okay . Perfect . We feel very confident in the recruiting . You know , the ability to recruit for that trial .
Speaker #3: We have multiple sites in Australia , including a major col . We'll be speaking at our event on December 11th . Who were heavily engaged in recruiting and are confident that we will recruit that trial on time .
Speaker #3: And for in terms of when we would expect to see efficacy , we're looking to have an interim readout . That'll be in the early part of the second half of next year .
Speaker #3: And that's going to look at a 12 week , a 12 or , sorry , a a 13 week time point where we'll not only we're going to be obviously measuring safety and tolerability to the Sad .
Speaker #3: And we'll see that data well before the second half . But in the second half for efficacy , we'd look at that 13 week readout .
Speaker #3: We expect to see significant hair growth in the terminal area , hair count relative to baseline . We'll be doing additional measures of efficacy at the 20 week and the and the 24 week as .
Speaker #6: Gotcha . Thank you .
Speaker #4: Your next question comes of from the line Gil Blum . Please go ahead and provide the company you're with .
Speaker #7: Good afternoon . And thanks for the update . So maybe one on Tl1 a quick just to understand the features here . So the half life wasn't as much as a second gen asset , but you mentioned that the Adas didn't affect the PK .
Speaker #7: Where do you think that fits the asset as it relates to an indication ? I mean , is this one of the reasons you're looking at an alternative indications and have a follow up ?
Speaker #3: Are you may be on mute . This is Zach . I can take that question . Look , we looked at the profile and full disclosure , you know , we're we're still waiting for data to come in on the highest dose patients before we have a final read on what the half life looks like .
Speaker #3: But in our assessment , the is molecule safe , well tolerated . We did not see an effect of Ada on PK as well , but we do think it has an additional advantage which will be getting better measurements around , which is tissue distribution , which potentially could lead to better efficacy in a number of indications .
Speaker #3: And this is one of the areas that's focused gotten us on a couple of newer the indications where molecule could be first in class .
Speaker #7: that's Okay , that's helpful . And as it relates to endometriosis , just to clarify , are we looking initially at a subcu dosing or also IV first ?
Speaker #3: Yeah , great . Great question . Gil , I our view think oh go ahead , Sean .
Speaker #2: Oh hey . Sorry I got kicked off there for for a minute . Yeah . So the plan would be subcu in the phase two .
Speaker #2: Very similar to how we're planning on on running the Aiga trial . As we mentioned previously , we're at 200 mgs per per mil , and the sad we'll do portion in IV and then go to the Subcu in the Mad .
Speaker #2: And then the same with the endometriosis trial as well.
Speaker #7: So you'll use Subcu initially and endometriosis. Just want to make sure I understand.
Speaker #2: Yes . In that phase two trial we that is the plan to use Subcu .
Speaker #7: Okay . And maybe the last point just to make sure . So focus remains both on Aga and Endo . Not not Endo taking the lead here is that correct ?
Speaker #2: 100% . We I would say that they are they are co-leads . Our main focus this this next year is to to get a the phase two readout in in Aga and then the year following it would be endometriosis .
Speaker #2: So the the plan is still full steam ahead on on Aga . Nothing has changed on on that front at all .
Speaker #7: Okay . Thank you for taking our questions .
Speaker #5: And maybe maybe , maybe its important also to to even add that of course the phase two trial . And individuals is takes full advantage of the phase one trial in Aga .
Speaker #3: Yeah , back to this is put a finer point on that , it's a very capital efficient development plan . Since the phase two trial in endometriosis will leverage all the safety data we generate in the phase one two trial in Aga .
Speaker #4: Your next question comes from the line of Ryan Chang with J.P. . Please go ahead .
Speaker #8: Hey , guys . Thanks for taking our questions this evening . As we think about the timing of the interim alopecia data , and also the start of the phase two endometriosis trial next year .
Speaker #8: Will you want to wait for the interim data from alopecia before you start the endometriosis ? Endometriosis trial ? Just curious if there's any read through between the two items .
Speaker #2: So obviously we're going to have to get the the sad safety portion before going into the phase two study . But assuming the the phase one FOD data looks good from the Aga trial , we plan to march full steam ahead in terms of going into endometriosis , and we yeah , we do not plan to wait to see the Aga readout before starting that that phase two .
Speaker #2: .
Speaker #8: Got it . And maybe just one quick one about what we have seen so far from home . Medicines 115 . Specifically in endometriosis much .
Speaker #8: research do How you see from 115 to your 201 so program far ? And and you how are using the data that they have seen to your own advantage ?
Speaker #2: . Absolutely Zach , do you want to take that question ? And
Speaker #3: Yeah , absolutely . Yeah , absolutely . You know , we look at that trial design was not the best . So there's definitely some learnings there .
Speaker #3: And you can be assured we will have a well design trial that's adequately powered . But the key point that we take away from that trial that I think is very encouraging for proof of concept in the endometriosis , is the following one .
Speaker #3: The first point being they saw in their effect size , they saw a dose response during treatment . During the 12 weeks of treatment and the statistically significant response in pain for the high dose .
Speaker #3: And this is in dysmenorrhea . So this would be the primary endpoint or one of the primary endpoints we would look at in our trial as well .
Speaker #3: So we find that to be very encouraging . I think there's some learnings from , as I mentioned , the way they structured designed the and trial where we will be sure to power correctly and make sure we design for entrance requirement with a little more rigor .
Speaker #3: But we think it's , like I said , a very encouraging proof of concept that de-risk the mechanism .
Speaker #8: Great . Thank you .
Speaker #4: Your next question comes from the line of Stephen Deckert with KeyBanc . Please go ahead .
Speaker #3: Hey , thanks , guys .
Speaker #9: Just wondering if the ex vivo results you with 201 are better than expected or generally in line with what you thought , and then could two one be expanded to additional indications ?
Speaker #9: Thank you .
Speaker #2: Regarding Yeah . the ex vivo data , obviously when you're dealing with , you know , human biopsies , you know , a lot of things can can go wrong and from what we saw just from the biomarkers that that were up upregulated , you know the stem cell growth that we saw that was driving the hair shaft production as well as the melanin production for Repigmentation .
Speaker #2: All of that was was really , really exciting to to see . And it validated that the mechanism in in really fantastic way and it lines up really nicely with what you're seeing in the stump tailed macaque data .
Speaker #2: As well as the mouse shaving study that that we did . And so we think it just ties together everything really nicely . And this was , you know , in , in of three , three , three different patients and you know , you saw the same response across all three patients .
Speaker #2: And so we yeah , were just really pleased with with what we saw . And I think that gives us , you know , really strong confidence going into the , into the phase two study .
Speaker #3: And I'll add to that up to your second we do see question , potential additional indications for 201 . We're not ready to speak about those today .
Speaker #3: I think we're laser focused on driving that program through the phase one two way for endometriosis , for Aga , as well as the phase two for endometriosis .
Speaker #9: Got it . Thank you .
Speaker #4: Again , if you would like to ask a question , press star one on your telephone keypad . Your final question comes from the line of with your .
Speaker #4: Please go ahead . Again , your next question comes from the line of with tan KR . Please go ahead . Your final question comes from the line of Kripa Devarakonda with Truist .
Speaker #4: Please ahead go .
Speaker #10: guys , thank you so Hey much for taking my question . For the Endo program with 201 , can you remind me if you expect to be able to target all endometriosis patients ?
Speaker #10: Or if there is any restriction or subgroups would that you expect to target and I know really early , but when you think it's about drugs that are standard of care that have been commercialized in endometriosis , what do you see as the hurdles in this space ?
Speaker #10: As you take 2 or 1 forward ? Thank you .
Speaker #2: Yeah , that's a great question , Zach . I'll hand it over to you and then and then to Andreas .
Speaker #3: Yeah . Terrific question . I think a couple points here . One is we're looking to to to address patients that are on potentially displace GnRH therapy .
Speaker #3: Those have that therapy has a sort of unwanted side effects for reduction in bone mineral density . It does show some efficacy . But we think trying place to a new option in the that's more arsenal effective does not have a side effect profile like that could be game changing for these patients .
Speaker #3: So that's our mission . In terms of how we recruit and segment the trial . That's something we'll comment on later next year as we get closer to the start of the trial .
Speaker #3: And if you'd like to add something , please feel free .
Speaker #5: Yeah . I mean , so these are two different aspects . you know , what do we believe where it will work versus what's the design of the trial .
Speaker #5: So from the scientific rationale , there is only reason to believe that the prolactin receptor antibody should work in every endometriosis patient . Because we do in know that endometriosis patients you do have an increased prolactin receptor as well as prolactin expression in the endometriosis lesions , as well as in sensory neurons .
Speaker #5: Therefore having an effect on both the reduction of lesions as well as as on the pain aspect . And this of course , is going to be sex hormone independent effect , which is critical .
Speaker #5: So we can with with all rational applied say there shouldn't be any female patient with endometriosis , which should not be potentially treated with a prolactin receptor antibody .
Speaker #10: Thank you so much .
Speaker #4: That ends our Q&A session . I will now turn the call back over to Sean McClain founder and CEO for closing remarks . Please go ahead .
Speaker #2: Yeah , I just want to first thank our team at Absci for all the hard work . They've put in to not only getting 201 into Aga , but now expanding into endometriosis and want to thank all of our investors and for analysts all the support .
Speaker #2: We're really excited about what's what's ahead . And we have some exciting catalysts over the next 24 months . So look forward for another exciting year .
