Absci Q2 2026 Earnings Call Transcript

Key Takeaways

  • ABS-201 interim Phase 1 results were encouraging: Management reported favorable safety and tolerability, with an estimated half-life of at least 65 days and modeling suggesting two to three doses could maintain more than 90% prolactin-receptor occupancy over six months.
  • Multiple upcoming clinical catalysts remain on schedule. The company expects interim 13-week proof-of-concept data for pattern hair loss later in 2026, full 26-week data in early 2027, and plans to initiate a Phase 2 endometriosis study in the fourth quarter of 2026.
  • Eli Lilly partnership and new financing strengthen resources. Lilly invested $40 million and is collaborating on ABS-201’s clinical development, while Absci’s June financing generated approximately $93.6 million in net proceeds and extended projected funding into the second half of 2028.
  • Absci is expanding its AI drug-discovery platform with Atlas, which integrates literature, genetics, and single-cell data to identify targets before feeding them into the Origin molecule-design platform; management said the technology has already suggested additional prolactin-related indications.
  • The company remains dependent on unproven clinical and commercial assumptions: durability of hair regrowth will not be established by the 13- or 26-week readouts, and the cited market opportunities and product profile are based partly on modeling, consumer research, and hypothetical profiles rather than clinical efficacy results.

Sean McClain
Sean McClain
CEO at Absci

Thanks, Alex. Good afternoon, everyone. Thanks for joining us today. Absci continues to execute, and I'll walk you through recent highlights, including key progress on ongoing HEADLINE trial, our new partnership with Eli Lilly, and our $100 million financing completed at the end of June. Starting with HEADLINE. In June, we released positive interim phase I data.

Sean McClain
Sean McClain
CEO at Absci

The data suggests the study drug was well-tolerated with favorable safety and tolerability. Based on interim PK data, ABS-201's half-life supports the potential for just two to three injections over six months. This is exactly why we built our AI platform, to design molecules that meet our target product profile we set out from day one.

Sean McClain
Sean McClain
CEO at Absci

You've heard us say the prolactin mechanism is underappreciated. Everything we've learned has only strengthened that conviction, and we believe targeting the prolactin receptor has the potential across numerous diseases.

Sean McClain
Sean McClain
CEO at Absci

We are also excited to have a partner who shares in that vision. As you saw in June, we announced that Eli Lilly made a $40 million strategic investment in Absci. Our partnership with Eli Lilly is tailored around the clinical development strategy for ABS-201. As a part of this collaboration, we are happy to be welcoming a representative from Lilly onto our Endometriosis Advisory Board.

Sean McClain
Sean McClain
CEO at Absci

Zach will provide more details of this partnership later in the call. In addition to Lilly, we've seen elevated interest from the investment community in prolactin biology. In June, we completed a $100 million financing, including the $40 million investment from Lilly, from a group of blue-chip investors. We're grateful for this support, which enables the continued development of our existing programs as well as future expansion of our pipeline.

Sean McClain
Sean McClain
CEO at Absci

ABS-201's progress is a testament to the platform and the team that created it. Building on that leadership in de novo antibody design with Origin, we've now extended the platform upstream with Atlas, Absci's target to lead autonomous scientist. Atlas is an agentic discovery engine built to remove the bottleneck ahead of design, rapidly identifying and validating the right targets.

Sean McClain
Sean McClain
CEO at Absci

Atlas integrates literature, genetics, and single-cell sequencing data to surface and triage novel target hypothesis. These flow directly into Origin for epitope-specific de novo design and then into our in-house wet lab for characterization and pathway validation. This process closes a hypothesis to molecule loop and turns discovery into a high throughput fail fast engine by having more shots on goal and better ones. We're already seeing this at work.

Sean McClain
Sean McClain
CEO at Absci

Atlas has surfaced potential new indications for our prolactin receptor franchise and independently recovered genetic evidence linking this pathway to pattern hair loss and endometriosis.

Sean McClain
Sean McClain
CEO at Absci

This is a powerful new tool that every drug hunter at Absci can now leverage. We'll continue deploying this AI-native platform to create therapeutics like ABS-201 with the potential to change the treatment paradigm for patients. With that, I'll turn it over to Ransi to walk through the ABS-201 clinical program. Ransi.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

Thanks, Sean, and good afternoon, everyone. in June, we released positive interim phase I data from the ongoing HEADLINE trial of ABS-201. We continue to be encouraged by the emerging safety, pharmacokinetic, and immunogenicity profile observed to date. As we said in June, blinded aggregate interim data suggests study drug was well-tolerated and exhibited a favorable safety and tolerability profile.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

Additionally, based on available interim pharmacokinetic data across all four single ascending dose cohorts, half-life for ABS-201 is estimated to be at least 65 days. These results support the potential for dosing two or three times over a six-month period, pending confirmation through continued follow-up across all cohorts.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

Additionally, new modeling continues to suggest that two to three doses of ABS-201 over six months would be able to achieve greater than 90% receptor occupancy, which we believe is a key driver of meaningful clinical efficacy for hair growth.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

These new data are available in the updated corporate deck published on our website today. We are very eager to share our clinical data with you once it's available. Today, we are pleased to share that the multiple ascending dose portion of the study continues to enroll according to plan.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

We continue to anticipate an interim proof of concept readout in the form of 13-week data later this year. Then, we anticipate our full proof of concept data in the form of 26-week data in early 2027. As a reminder, the HEADLINE trial is a randomized, double-blind, placebo-controlled study.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

The primary endpoints are safety and tolerability, while secondary endpoints include PK, PD, immunogenicity, target area hair count, target area hair width, and target area darkening pigmentation. We will also collect patient-reported outcomes data in this study. The prolactin receptor mechanism for hair growth is unique.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

Unlike minoxidil, finasteride, or nutraceuticals, the mechanism underlying ABS-201 is regenerative for the hair follicle, protecting and promoting hair follicle stem cells, restoring CD34 progenitor cells, and stimulating key growth factors IGF-1 and FGF7, while decreasing the catagen-driving TGF-beta 2.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

This regenerative mechanism is unique to the anti-prolactin receptor pathway and supports the significant durable effects with potential to grow new hair in dormant follicles. Our clinical study is designed to showcase this unique mechanism with our 13-week assessment, which is interim in nature, intended to provide a directionally positive signal. Has the mechanism begun to take hold, and is it building all the machinery and building blocks we see responsible for regenerating the hairs?

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

A directionally positive signal of hair growth at 13 weeks would give us even further confidence in seeing more robust hair growth at 26 weeks and beyond, as is supported by preclinical data in the stump-tailed macaque.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

Altogether, the preclinical stump-tailed macaque data, as well as our human ex vivo data from skin biopsies of both male and female donors, provide robust support for this mechanism and its ability to provide durable hair growth.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

We are also excited to be progressing our ABS-201 program for endometriosis. As Sean mentioned earlier, we are pleased to be welcoming Axel Haupt, M.D., Senior Vice President, Clinical Investigation at Eli Lilly and Company, onto our Endometriosis Advisory Board.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

With the safety, tolerability, and PK data generated in the SAD portion of the HEADLINE trial, we anticipate initiating a phase II study for endometriosis in the fourth quarter of this year. With that, I'll pass it over to Zach to discuss our business strategy and to provide an update on our financials. Zach.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

Thanks, Ransi. We continue to focus our strategy on creating and advancing high-value pipeline programs like ABS-201. Our primary objective today is the successful execution of our clinical trial for ABS-201 in male and female pattern hair loss and in endometriosis.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

We are also advancing a preclinical pipeline focused on immunological and inflammatory indications that fit into our broader strategy, including programs that can ultimately be commercialized direct to consumer.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

The clinical trial for ABS-201 continues to progress according to plan. We believe this program offers an outsized ROI based on its relatively capital-efficient clinical development plan and significant market opportunity.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

Based on our market research, we estimate a potential total available market greater than $25 billion in the U.S. alone. In addition to pattern hair loss, we also see a significant multibillion-dollar market for endometriosis, with potential peak sales of over $4 billion.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

These programs are emblematic of how we prioritize and allocate our resources to programs that offer high ROIs based on addressing large underserved patient populations. We are leveraging our leadership in prolactin biology by advancing ABS-201 towards proof of concept in both pattern hair loss and endometriosis, and by progressing our preclinical anti-prolactin receptor program, ABS-202, in an undisclosed I&I indication.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

We are also actively exploring other potential underserved indications for which prolactin receptor inhibition could offer a differentiated therapeutic mechanism. We look forward to sharing our interim proof of concept data in pattern hair loss later this year and our full proof of concept data early next year.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

As a reminder, our consumer research survey, as well as input from leading KOLs, inform our view that a 26-week increase in target area hair count of 30 to 35 hairs per centimeter squared, roughly on par with high-dose oral minoxidil, would enable a home-run product.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

Our consumer and KOL research support an estimated $25 billion TAM associated with such a hair growth effect size, given ABS-201's expected unique durability and administration convenience.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

We believe a target area hair count result above that level would expand the market further, and that a less robust result would still unlock a multibillion-dollar market opportunity. ABS-201, with its novel prolactin receptor mechanism, is positioned to become a new premium category of pattern hair loss therapy, offering consumers convenient, durable, regenerative hair growth. Continuing to execute the development of this program remains our top strategic priority.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

Our platform continues to evolve and deliver new capabilities and efficiency gains. As you will recall, our first programs were advanced through IND-enabling studies in under 2 and a half years and under $15 million in total cost. Based on our current Origin model improvements in combination with our agentic Atlas platform, we believe we can significantly improve on these metrics.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

For example, our latest Origin models allow for a 1,000x reduction in library size for identification of high-quality leads. We are also finding ways to reduce IND-enabling study timelines based on the quality of our AI-designed drug candidates, which, for example, are well-suited to high-concentration formulation development. We anticipate additional efficiency and capability improvements as we further advance our platform. We are grateful for our partners, new and existing, for their support.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

As discussed, we are excited to be collaborating with Eli Lilly and to welcome a member of their leadership team onto our Endometriosis Advisory Board. Our partnership with Eli Lilly is tailored around the clinical development strategy for ABS-201 and does not confer rights to the program, which we plan to develop ourselves.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

We appreciate Eli Lilly's support, as well as their interest in prolactin biology within pattern hair loss, women's health, and beyond. Turning now to our financials. Research and development expenses were $22.6 million for the 3 months ending June 30, 2026, as compared to $20.5 million for the prior year period.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

This increase was primarily driven by advancement of Absci's internal programs, including direct costs associated with external preclinical and clinical development of ABS-201, offset by a decrease in personnel-related costs.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

Selling, general, and administrative expenses were $9.2 million for the three months ending June 30, 2026, as compared to $8.5 million for the prior year period. This increase was primarily due to stock-based compensation and other administrative costs.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

Cash, cash equivalents, and marketable securities as of June 30, 2026, were $201.1 million as compared to $125.7 million as of March 31, 2026. in June, we completed an underwritten offering of common stock.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

The net proceeds from the offering were approximately $93.6 million. Our current balance sheet, including this additional capital, supports our execution of key upcoming catalysts and continued progress of our early-stage pipeline, as well as an expansion of our planned endometriosis clinical trial. As we finalize our clinical trial design, we anticipate sharing additional details of the endometriosis clinical development plan later in the third quarter.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

Based on our current projections, we now believe our cash equivalents, and marketable securities will be sufficient to fund our operating plan into the second half of 2028. With that, I'll now turn it back to Sean.

Sean McClain
Sean McClain
CEO at Absci

Thanks, Zach. As always, I want to thank the Absci team for making all this possible. I'd also like to thank Eli Lilly for their partnership and all of our investors, both new and existing, for their support. We're fast approaching pivotal moments for Absci. Our first look at interim POC data for pattern hair loss is anticipated later this year.

Sean McClain
Sean McClain
CEO at Absci

Our full 26-week POC data should follow early next year, where we anticipate showing robust hair regrowth from our regenerative prolactin mechanism. I'm incredibly excited for both of these readouts. We're energized for what we're building in our early-stage pipeline.

Sean McClain
Sean McClain
CEO at Absci

We see a huge opportunity to capitalize on the interest in total vitality, combined with consumer shift towards more direct-to-consumer and cash pay products. Our current and future pipeline focuses squarely on these emerging trends. We continue to fire on all cylinders, and I can't wait for everyone to see the results of our hard work in the coming months. Operator, let's open the call for questions.

Operator

Thank you. As a reminder, to ask a question, please press star one one on your telephone and wait for your name to be announced. To withdraw your question, please press star one one again. in the interest of time, we do ask that you please limit your questions to one question and one follow-up. Please stand by while we compile the Q&A roster. Our first question comes from Brian Cheng of JPMorgan. Your line is open.

Brian Cheng
Brian Cheng
Analyst at JPMorgan

Hey, guys. Thanks for taking our question this afternoon. Maybe just to start off, we noticed that your indication on your press release is now defined as pattern hair loss. I think in the prior communication, you have been indicating the lead indication as androgenetic alopecia. Is there any read, or in terms of how you're defining the target indication today, is there any change in terms of the lead indication for 201? We have a quick follow-up. Thank you.

Sean McClain
Sean McClain
CEO at Absci

Yeah. Thanks, Brian. It's a great question. We decided to change the name for two reasons. First, if you think of androgenetic alopecia, it implies the androgen receptor, and we know that targeting the androgen receptor, such as finasteride or other androgen receptor antagonists, do not fully regrow hair. We do have evidence that does support that prolactin looks to sit upstream of the androgen receptor and actually drives androgen receptor expression.

Sean McClain
Sean McClain
CEO at Absci

Based on the underlying biology and the importance of prolactin within pattern hair loss, we decided to switch the name from androgenetic alopecia to pattern hair loss. Additionally, we had gotten feedback from other KOLs that they thought that this was a more appropriate name.

Sean McClain
Sean McClain
CEO at Absci

The last piece is on the consumer front. We think that pattern hair loss is much better understood amongst consumers than androgenetic alopecia. For all of these reasons, we have changed the name but not the indication itself. Ransi and Zach, please chime in if there's anything else I missed there.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

Yeah. Thanks, Sean. I mean. Sorry, go ahead, Zach.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

No, no, go ahead, Ransi.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

I think the term pattern hair loss also encompasses the entire population. We are still studying the same population, or indication encompass the same population. But really, when you think about the disease state in the U.S., there is 80 million people, and 30 million of those are women. So we think the term pattern hair loss is more appropriate to describe who it is that we are targeting.

Brian Cheng
Brian Cheng
Analyst at JPMorgan

Thank you, Ransi. Just a follow-up.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

I was just going to add, too, that the change in name does not have any impact on how we've assessed the market opportunity. It's still fundamentally the same market opportunity, number of patients, and our consumer surveys were focused on identifying that. This does not have any effect on those estimates.

Brian Cheng
Brian Cheng
Analyst at JPMorgan

Thank you. That's very helpful. As a follow-up, I think in our prior discussions, we all have a pretty good sense of what we want to see in terms of non-vellus hair count at week 13 and week 26 from your MAD portion.

Brian Cheng
Brian Cheng
Analyst at JPMorgan

Just looking at other metrics, I think you have mentioned that the terminal to vellus ratio metric is also super important in terms of giving you a directional insight of whether ABS-201 is giving you some benefits towards the goalpost.

Brian Cheng
Brian Cheng
Analyst at JPMorgan

Can you help us think about what is the magnitude that you want to see in terms of T to V ratio? I'm also curious if you have a sense of what some of the current standard of care can offer in terms of the ratio changes at around week 13. Thanks for your help.

Sean McClain
Sean McClain
CEO at Absci

Yeah. Ransi, do you want to take that one?

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

Yeah. It's an interesting question. I think we're, at least for the interim, we're interested in a broad set of data. I'm particularly not focused on a specific V to T ratio. I honestly, Brian, I'm not sure I've seen specific V to T ratios from other programs, so can't really answer that one for you.

Sean McClain
Sean McClain
CEO at Absci

Yeah.

Brian Cheng
Brian Cheng
Analyst at JPMorgan

Got it. Thank you.

Sean McClain
Sean McClain
CEO at Absci

I think how we're thinking about the 13-week is really looking at not only the terminal, also V to T, but also the potential to regrow hair in dormant follicles, whether that comes up as a terminal hair, a vellus hair, or you have more V to T transition. I think the key point with this readout is being able to show potentially new mechanisms that other drugs do not show.

Sean McClain
Sean McClain
CEO at Absci

I think regrowing that dormant follicle where you've been bald for many years, if we start to see changes there, again, whether it's on the vellus hair or the terminal hair, we think that that's really exciting and could be a big game changer for this particular mechanism, in addition to the regenerative aspect.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

Brian, that's why we talked about total hair count in the past, and that encompasses what Sean was just talking about.

Brian Cheng
Brian Cheng
Analyst at JPMorgan

Thanks, guys.

Operator

Thank you. Our next question comes from Brendan Smith of TD Cowen. Your line is open.

Brendan Smith
Brendan Smith
Analyst at TD Cowen

Great. Thanks for taking the questions, guys. I wanted to just first clarify quickly on ABS-201. Is it maybe fair for us to assume you will get the interim data in hand, put it out before initiating endometriosis study, and then full POC hair loss data in Q1 thereafter?

Brendan Smith
Brendan Smith
Analyst at TD Cowen

Is that kind of just fair assumption on the order of events coming up there? To follow up on the platform itself, it sounds like the plan outside of prolactin receptor is still largely develop targets, out-license prior to entering the clinic on your own.

Brendan Smith
Brendan Smith
Analyst at TD Cowen

If that is the case, I guess just wondering on a strategy level how we should think about potential cadence of new assets coming out of the platform if you kind of have a target partner deal cadence in mind, just any color there on output that we should keep in mind over the next, I do not know, call it 18 months. Thanks, guys.

Sean McClain
Sean McClain
CEO at Absci

Yeah, thanks, Brendan. To your first point, I think that that is a fair assumption. On the second point, we are planning on taking ABS-201 to market ourselves and everything that we have coming behind ABS-201, we are looking at it from the lens of what could we commercialize ourselves, what could potentially be a DTC that you could sell alongside ABS-201 and then make the determination, do we have the capital?

Sean McClain
Sean McClain
CEO at Absci

Is the cost capital right to continue to develop this ourselves, or do we want to find a partner given the indication or the cash situation? Everything we are developing would be with that commercialization in mind, and then we have the optionality to partner. That is the current strategy we have. Zach, please chime in as well.

Zach Jonasson
Zach Jonasson
CFO and Chief Business Officer at Absci

Yeah, I think you said it well, Sean. I think the only other point I would make is, Sean described some of the advances in our platform. We're becoming more and more efficient at generating new molecules and new programs, so I think we will be creating a lot of optionality for ourselves. But to Sean's point, we're very rigorous about providing a strategic and ROI-based perspective on which programs we will advance with our own balance sheet versus the ones we'll partner.

Operator

Thank you. Our next question comes from Vamil Divan of Guggenheim. Your line is open.

Vamil Divan
Vamil Divan
Analyst at Guggenheim

Great. Thanks for taking my question. Maybe one quick follow-up on the conversation around the partnerships. I think last year you guys had talked about likely signing a partnership by the end of the year, and I don't know if that's happened or not. So I'm curious, would all your partnerships be disclosed?

Vamil Divan
Vamil Divan
Analyst at Guggenheim

Is there any, or have you signed any since later last year that maybe just were not disclosed publicly? So maybe any sort of update on that side would be helpful. Then the other question I have is just around this 13-week data, which obviously everyone's eagerly waiting for, then just to maybe level set expectations, if you can share what you plan to disclose in the headline release so we all kind of know what to expect there.

Vamil Divan
Vamil Divan
Analyst at Guggenheim

Tied to that, I know one of the big potential selling points of 201 would be the durability of the hair that's regrown. We're not going to know that at 13 weeks, obviously. So I'm just trying to get a sense of how you think about how long the duration of follow-up would need to be before you start getting comfort that this dosing regimen, that your target profile is the right dosing regimen for the durable response. Thanks.

Sean McClain
Sean McClain
CEO at Absci

Yeah, thanks, Vamil. So in terms of partnership, the partnership that we had inked with Eli Lilly, both the investment and the collaboration on ABS-201 on clinical development, we do see that as achieving that large pharma partnership. With regards to the top-line readout for the 13 and 26 week, I'll hand that over to Ransi.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

Hey, Vamil. Thanks for the question. Yeah, so we're going to show the data that we think will give us that interim look, just a sort of a status check on what the drug is doing. We've talked about

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

total area hair count, so that'll be their target area hair count, which is the terminal hairs. We'll get a look at target area hair width to see how wide the hair caliber is. We'll be looking at darkness as well. I think those are the big things. In addition, we'll have a look at the updated safety and tolerability data as well.

Ransi Somaratne
Ransi Somaratne
Chief Medical Officer at Absci

Great question on the durability. We are actively working on trying to figure out how we can get that from this study. It's not going to be answered in the 13 or the 26 weeks. We do have a safety follow-up period after this trial. That's probably the first indication of durability of effect, and we'll get the same duration of safety follow-up on the cohorts. It's based on PK.

Sean McClain
Sean McClain
CEO at Absci

We're looking at what to do thereafter in terms of describing the durability of effects. More to come on that.

Operator

Thank you.

Vamil Divan
Vamil Divan
Analyst at Guggenheim

Okay. Thank you.

Operator

Our next question comes from Kambiz Yazdi of BTIG. Your line is open.

Kambiz Yazdi
Kambiz Yazdi
Analyst at BTIG

Hi, team. Thank you so much for the question. It appears from your modeling that you confirmed ABS-201 can maintain greater than 90% prolactin receptor occupancy without cycling. How should the greater, more sustained receptor occupancy impact efficacy compared to other prolactin receptor antibodies in pattern hair loss, and then secondarily, as in endometriosis? Thank you so much.

Sean McClain
Sean McClain
CEO at Absci

Yeah, it is a great question, and we actually just put out some modeling on the website today with the updated corporate deck. I think it is a very clear illustration. If you look at HMI-115, the once every 2-week dosing at 240 milligrams, you saw this oscillation that occurred between 60% and 70% receptor occupancy. We know that the receptor occupancy for the prolactin receptor needs to be well above 90% to achieve the signal blocking that is necessary.

Sean McClain
Sean McClain

Even a little bit of receptor left can cause quite a bit of signaling through the prolactin receptor. Essentially, the HMI-115 molecule, with that oscillation and not achieving the receptor occupancy, our belief is that they essentially were not able to achieve the efficacy because they were not able to get that prolonged anagen phase. That is what we believe that we are going to be able to achieve now.

If you look at, again, the receptor occupancy, those 2 to 3 doses were well above 90%, and we can ensure that the follicle can stay in the prolonged anagen state in order to rebuild that stem cell niche. Hair growth does not happen overnight. You need that sustained period of blockade in order to get the regrowth.

I think the really exciting part is if you look at the stump-tailed macaques when you got the greater than 90% receptor occupancy, you saw a really, really robust efficacy there. We are obviously targeting 30, but I do believe that if you hit the receptor appropriately to stay in the anagen state, I think you have the potential for even further upside than what we have been discussing. I think it is a really exciting opportunity with the PK profile that we have been able to achieve.

Then a quick follow-up. How do you expect that to impact endometriosis?

Ransi, do you want to take that one?

Yeah, happy to. I think it's the same philosophy, Kambiz. If you look at the other prolactin receptor antibody, they published their data in The Lancet, and you saw that there was an effect on dysmenorrhea at the highest dose.

We think the same principle applies, in that you have to really achieve that high level of receptor occupancy to see efficacy there. So even though it's a disease state that's quite different from pattern hair loss, we think the same principle is in play.

Good afternoon, and thanks for squeezing me in. We saw some interesting data for the oral minoxidil extended-release from Veradermics in women. Do you think the data that they put out changes maybe where the bar is as it relates to hair regrowth, or it doesn't really matter as it relates to your own programs? Thank you.

Sean McClain

The data that they put out clearly shows that standard of care is really poor, even with what they have. There is so much more room to improve from a standard of care perspective, and that is something we're very excited about.

We recently showed the female ex vivo data. It looked very similar to what we saw in the males. We're very excited to get this cohort kicked off in the study in female patients. I think that there is a real exciting opportunity just due to the really, really poor standard of care out there.

Thank you. This concludes the question and answer session and also today's conference call. Thank you for participating, and you may now disconnect.
