Operator

Good afternoon, and welcome to the Accelerine, Inc. Conference Call to discuss the company's 2nd Quarter 2024 Financial Results and Other Corporate Updates. This conference call is being recorded today, August 13, 2024. I would now like to turn the conference call over to Tyler Marciniak, Vice President of Investor Relations and Corporate Affairs. Tyler?

Speaker 1

Thank you, Carmen. Good afternoon, everyone, and thank you for joining us. Before we begin, I'd like to remind you that this conference call may contain forward looking statements such as those related to progress of our clinical trials and anticipated data readouts, our future financial and operating results and projected cash runway, and our ability to commercialize our product candidates. These forward looking statements involve risks and uncertainties that could cause our actual results and events to differ materially. We would urge you to review the Risk Factors section of our Form 10 Q for the quarter ended June 30, 2024 and additional Form 8 ks that we filed with the SEC, both of which are also available on our website at acelerant.com along with today's press release and our slide presentation.

Speaker 1

Additionally, these statements are based on information available to us today, August 13, 2024, and we undertake no obligation to update them as circumstances may change. The agenda for today's call is on the screen. We will review the corporate strategy updates announced in our press release as well as positive top line data from the Phase 3 trial of isokayvet and hidradenitis suppurativa. We will also provide an update on the Lonagutumab program in TED and close with a financial update highlighting our projected 3 year cash runway covering multiple anticipated milestones. Joining us on today's call are Mina Kim, our Chief Executive Officer Doctor.

Speaker 1

Shep Mpofu, our Chief Medical Officer and Gil Labroucherie, our Chief Financial Officer and Chief Business Officer. I will now turn the call over to Mina.

Speaker 2

Thanks, Tyler, and thanks everyone for joining us today. Earlier today, we announced positive Phase 3 results for Isaac Heibab in the Hidradenitis Suppurativa as well as details of a refocused pipeline strategy and plan designed to extend our cash runway to mid-twenty 27. We'd like to provide more details on this call. First, we're very pleased to have achieved a positive Phase 3 readout for ISAK HiBEV in HF. We met the primary endpoint of Hi Score 75 and are especially pleased with the compelling response rates in Hi Score 90 and 100 within 12 weeks of treatment, an effect we believe has not been previously observed by other agents.

Speaker 2

While the primary endpoint was measured at 12 weeks, we continue dosing patients in a placebo controlled manner through week 16. We have data from 2 thirds of the trial participants who completed week 16 and these preliminary data further demonstrates deepening of responses over time. These data follow the positive PSA Phase IIbIII readout we announced earlier this year and which were presented in the late breaking session at EULAR in June. Collectively, the data in HS and PSA further validate our longstanding view that isakaydab has the potential to be an effective therapy that is approvable in multiple indications. As we have previously stated, we will make disciplined and capital conscious decisions.

Speaker 2

We've determined that a program of this breadth and size is best brought to market by a larger organization with more resources in an existing footprint in the therapeutic areas of interest. Over the past several months, we've been evaluating where to prioritize investments to maximize the success of our pipeline including lonagutomax, which we believe has the potential to improve upon clinical response and convenience versus the standard of care in thyroid eye disease. We plan to complete the ongoing trials of isokayveb in HS and PSA, but we will not start new trials in these indications. We do plan to continue the ongoing Phase 2bthree trial in uveitis through to its primary endpoint with top line data expected in the Q4 of 2024. There's high unmet need in uveitis and a compelling scientific rationale for the IL-seventeen to 2 50 patients would be required for registration.

Speaker 2

To 250 patients would be required for registration. The ongoing trial is fully enrolled with approximately 100 patients. In addition to these isotype based updates, we've decided to stop internal development of SLR-five seventeen, our early anti cKIT program. Data from healthy volunteers demonstrated molecular activity, but we have made the decision to de prioritize this program. Finally, this refocused pipeline also requires a different organizational structure and we are executing an approximately 33% reduction in force.

Speaker 2

I want to take a moment to pause and thank our colleagues who were impacted by this restructuring. They played an important role in our growth and I wish them the very best in the future. While these decisions are difficult, we're confident that they are the right ones to enable Accelerate's long term success. We remain committed to high quality execution that's disciplined and capital conscious. These program decisions as well as the organizational restructuring enable us to move forward aggressively to develop lonagutumab and extend our cash runway to mid-twenty 27.

Speaker 2

By focusing future capital investment on Lonagutomab, we will be well positioned to fund our ongoing and planned TED trials through BLA submission. Shep will review our overall strategy and ongoing activity for lonagutumab in a moment, but I did want to make a few comments on the program. In terms of development strategy, the original plan had included a Phase 2bthree, but with the additional dose ranging that we are completing in patients in the ongoing Phase II trial, we will be able to go directly into Phase III program potentially with concurrent trials. We're currently planning to start the Phase 3 program in the Q1 of 2025. Additionally, we plan to meet with the FDA later this year and then host an investor presentation to provide additional Phase 2 data and details for the planned Phase 3 program.

Speaker 2

With that, I'd like to turn the call over to Shah.

Speaker 3

Thank you, Mina, and hello, everyone. I'm very pleased to share with you today positive Phase 3 data of isocipab in hydrodinitisupertiva or HS and provide a program update on Lonikutumab in thyroid eye disease. Let me start with HS. This regulated interleukin-17A activity plays a pivotal role in hidradenitisupertiva pathogenesis. Multi domain disease resolution is underachieved with available current therapies.

Speaker 3

An unmet need exists for therapies demonstrating efficacy across multiple disease manifestations, including abscess, inflammatory nodules and draining tunnels. Izocibab is a small protein therapeutic designed to selectively inhibit interleukin 17A with high potency through tight binding affinity. The small molecular size of isoquine attains the size of a monoclonal antibody, may enable tissue penetration and its albumin binding domain prolongs its half life and may enhance targeting to sites of inflammation in HS. Here you see the design of our global Phase 3 trial of isociparib in HS, which we expect will be the first of the 2 pivotal trials needed for registration in this indication. 258 patients were randomized 1 to 1 to receive either isokipab 160 milligram weekly or placebo.

Speaker 3

The inclusion criteria and design is similar to other Phase 3 studies with a primary endpoint here for the first time in a Phase 3 of high score 75 at week 12. At week 16, placebo patients were switched to receive isocopept 160 milligram weekly in the active treatment blinded period. As Mina mentioned, 2 thirds of trial participants have available week 16 data and we'll present those preliminary data today as well. Here we see patient demographics and baseline characteristics, which were well balanced between isokibe treatment group and placebo, typical of a patient population with moderate to severe HS and comparable to other global Phase 3 pivotal trials. 103 patients on the isotope arm and 112 patients in the placebo arm completed the study through week 12.

Speaker 3

Thus having approximately 20% on iZocubeb arm and approximately 13% on placebo arm discontinuing treatment with a delta of around 7% between the two groups. Please note the most common reasons leading to discontinuation on iZoxibab were mild AEs. And there were no notable differences between iZoxibab and placebo in terms of loss to follow-up and withdrawal of consent rates. In this trial, iZocubeB had a rapid onset of action associated with clear evidence of improvement within 2 weeks, achieving statistical significance as early as week 4. As mentioned, the study met its primary endpoint with 33% of iZOPPEB patients achieving a high score 75 response.

Speaker 3

That is a 75% reduction in abscess and inflamed nodules, this has 21% for placebo. Looking at the 2 thirds of patients with of week 16 data, we can observe an increase in response up to 40% on iZokibat, versus 20% on placebo. When we look at higher orders of response, looking at high score 90 and high score 100, iZokePEP again achieved statistically significant responses at week 12 versus placebo with approximately 1 in 4 patients on iZokipe achieving these deeper responses versus placebo. Notably the delta, so high score 9,000,000 and 100 were maintained at week 16. Here you see the response across the continuum of high score 50 to 100 as depicted from left to right on the slide.

Speaker 3

As expected, we observe a consistent trend with placebo response decreasing as the efficacy headwind increased at week 12. Clinical meaningful reductions in skin pain and improvements in DLQI were seen observed versus placebo at week 12 and also at week 16. The safety findings of isocibat were consistent with those observed in previous trials with the most common adverse event being mild to moderate injection site reactions in around 65% of patient on azacibab versus 8% in the placebo arm. You also note not much differences for other events like headache happening in 10% versus 9% and 7% of nasopharyngitis in both arms. Notably, there were no cases of Candida on iZokibab with only 3 cases showing in placebo.

Speaker 3

There was no IBD, liver toxicity, suicidal ideation behavior in the iZokebab treatment arm. In conclusion, iZokebab safety is in line with our past experience and iZokipeb appears to have the optimal to offer deep clinical responses across multiple HS domains, including skin pain and patient reported outcomes. We are very pleased to have successfully delivered this positive Phase 3 trial for iZotibab in HS, which builds on the Phase 3 data released in PSA earlier this year. Now turning our attention to Lonigutumab, which we are developing as a subcutaneous treatment for thyroid eye disease. Thyroid eye disease is an autoimmune disorder characterized by progressive inflammation that can lead to irreversible damage to tissues around the eye, threatening vision.

Speaker 3

Patients present with proptosis, cyclopia and a variety of disabling eye symptoms. It affects greater than 100,000 patients in the U. S. A high unmet need persists in thyroid eye disease, a multi faceted disease whose impact extends beyond the well recognized visual disfigurement. Patient quality of life is markedly impacted by TED, a therapy that provides rapid, deeper disease modifying effects that are durable across TED manifestation and results in improved patient quality of life, safety and convenience will be important for patients.

Speaker 3

Lonigutumab is a next generation recombinant humanized IgG1 monoclonal antibodies against human IGF-one receptor being developed to treat severe manifestations of TED. As shown in the middle cartoon on the slide, Lonigutma binds IGF-1R on a unique binding site, which we call an epitope and does not compete with IGF-one binding. It does this with high affinity with a kilo delta affinity measured around 30 picomolar and the specificity which triggers rapid internalization and degradation within minutes of the IGF-one receptor, thus eliminating it from the surface of the IGF-one expressing cells with potential to maintain IGF-one within homeostatic levels. IGF-1RI internalization prevents downstream signaling in orbital fibroblast from patients with TED and has been associated with therapeutic benefit in TED. The rapid and efficient suppression of IGF-one receptor signaling in TED with Lonigutumab could potentially improve clinical outcomes for patients by providing lower doses of exposure to achieve robust clinical response.

Speaker 3

As we saw in our proof of concept with 40 milligrams Q3W having responses at early time points when we assessed at 3 weeks after a single dose. There's potential for deep and durable responses with chronic dosing and ability to minimize safety risk by choosing an optimal convenient dose regimen. As I mentioned, we completed the Phase 1 proof of concept portion of our ongoing lonibutumab trial earlier this year. And we are now embarking on a dose ranging Phase 2 portion across 4 dose groups levels as you can see depicted on the right part of the slide projected. The Phase 2 trial was designed with the flexibility to test multiple dose levels and regimens in order to number 1, establish what we call a minimum effective dose when we are focusing on assessing the Cmin.

Speaker 3

And number 2, to enable establishment of an optimal dose selection for Phase 3 program within the optimal therapeutic window that you can see labeled on the y axis on the left part of the slide. And making sure that we don't have a Cmax that results in overexposure and therefore really calibrating an opportunity to minimize safety, which might be associated with high and over exposure. We are using the totality of this data to calibrate to an optimal dose level and convenient dose regimen. We recently initiated the final dose group with a dose level of 70 milligrams administered every 3 to 4 weeks in this Phase 2 trial to confirm the dose we will take to Phase 3. We believe our Phase II approach is unique and that it's patient centric designed comprehensively to address the ongoing unmet needs of thyroid eye disease patients and really balance benefit risk to define an optimal dose level and a regimen that profiles a robust therapeutic impact across the multifaceted aspects of TED.

Speaker 3

We are currently planning to start the Phase 3 trial in the Q1 of 2025. And as Mina mentioned, we are looking forward to meeting with the FDA later this year and sharing more information about the registrational program in Ted at a future investor event. Now I'll

Speaker 4

turn over to Gil. Thank you, Shep, and good afternoon, everyone. Today, I'm going to make a few comments on financial highlights from the quarter ended June 30, 2024 and then discuss some of the financial implications of the refocus pipeline and restructuring initiatives we announced today, the key milestones ahead for us and also provide year end cash guidance. We are fortunate to be in a strong financial position. At June 30, our cash position was approximately $635,000,000 For Q2, our R and D expense was 76,400,000 dollars as compared to $30,000,000 for the same period in 2023.

Speaker 4

A substantial majority of our R and D expense, approximately 75% is related to the Izo QIAVET program where we have been executing 3 Phase 3 programs this year in PSA, HS and uveitis. General and administrative expenses were $16,600,000 for the R and D and G and A expense includes stock based compensation expense of $10,200,000 which increased from $8,500,000 for the same quarter in 2023. Today, we made the difficult decision to right size our organization in line with our refocused pipeline strategy. I wanted to make a few comments on the financial implications of this decision. We expect to incur approximately $4,500,000 in cash based restructuring charges related to the workforce reduction.

Speaker 4

Our estimate for the cost associated with the completion of the ongoing Uveitis study, HS and PSA studies is expected to range between $30,000,000 $35,000,000 With respect to the ongoing iZokayvep CMC activities and commitments, we expect to incur between $55,000,000 $85,000,000 We are actively working with our manufacturing partners with a goal to mitigate these costs. From a financial point of view, our focus will be on efficiently and effectively executing this refocused pipeline strategy and associated restructuring, remaining disciplined and risk aware with our operational spend and significantly extending our cash runway out approximately 3 years to mid-twenty 20 7 through multiple value enhancing catalysts. This long range financial guidance includes adding an additional dose arm to our ongoing monagutinab Phase II trial as Shep just reviewed, funding 2 Phase III trials for monagutinab and BLA enabling activities for that program. In addition, please note that our cash runway guidance does not include any proceeds related to additional financing or partnering. We are very excited about the milestones ahead for Acceleron.

Speaker 4

We remain focused on our core mission to accelerate the development and delivery of transformative medicines in immunology. On this slide, we have outlined some of the important milestones for our development programs and related timing windows. Following our end of Phase 2 meeting with the FDA on the Lonagutinib program, we plan to hold an investor event focused on the unmet need for thyroid eye disease patients, the detailed rationale underpinning dose selection, outcome of the end of Phase 2 meeting with the FDA, additional data from the ongoing Phase 2 and the design of our Phase 3 development program. In addition, we also continue to project that we will have top line results from the Iso KiVap Phase IIbIII trial in uveitis before year end. We anticipate rapidly advancing monaglutinib into late stage development with the start of the Phase 3 program before the end of Q1 2025.

Speaker 4

We expect the first top line readout from the registration program in 2026 and to file a potential BLA thereafter. We look forward to sharing more details on our plans for the lanugumab program at our upcoming investor event. Now turning to forward looking financial guidance. We currently project our 2024 year end cash position will range between $420,000,000 $450,000,000 We expect our cash used in operations to increase substantially in the second half of twenty twenty four. Remember, in the first half of twenty twenty four, we received $37,000,000 from a one time vendor credit and licensing payments.

Speaker 4

Conversely, in the second half of twenty twenty four, we expect to pay a $31,000,000 option payment related to achieving proof of concept with onagutumab and non recurring payment for costs related to the restructuring and actually in certain isokayvah commitments. As I mentioned earlier, we now project our cash runway to mid-twenty 27, which we anticipate will fully fund the lanautumab development program through BLA filing, while also preserving capital for selective pipeline expansion. And as I stated earlier, our cash runway guidance does not include any proceeds related to additional financing or partnering. And now I'll turn the call back over to Mina.

Speaker 2

Thank you, Gil and Shaf, and thank you all for joining us on today's call. The decisions we announced today about our go forward strategy position us to execute on lonagutumab from a position of strength. By suspending new investment for isakibib and PSA and HS, discontinuing FLRN-five seventeen and the difficult decision to right size our organization. We can now focus on rapidly developing lonagutumab as the potential best therapy for thyroid eye disease. We have an outstanding team.

Speaker 2

We're positioned to deliver high quality execution of the pivotal program and we now have a cash runway to take the program through both pivotal trials. We're excited by the opportunity to serve the unmet needs of TED patients. Since taking on the CEO role a few months ago, I've had the opportunity to meet with many, probably more than 100 of our investors and I appreciate the opportunity to provide this update today. We look forward to providing regular updates on our progress and I hope you will join us for our investor event after our FDA meeting where we will provide an in-depth and comprehensive overview of the full lonagutumab opportunity and the many reasons why we're so excited to move this program forward. Thanks for joining us today.

Speaker 2

And operator, with that, we can open up to questions.

Operator

Thank you so much. And it comes from the line of Derek Archila with Wells Fargo. Please proceed.

Speaker 5

Hey, thanks for taking the questions. Just three quick ones from us. I guess first, what's the rationale for adding the 70 milligram dose in the ongoing Phase 2 for longagutimab? Also the every 3 week dosing arm as well. Just want to also figure out whether this is kind of leading to potentially a loading dose in Phase 3.

Speaker 5

So that's the first question. Second question just for Izzo. I guess is the plan to partner this asset right now or is it just going on the shelf? I just wanted to clarify in terms of the comments you made around uveitis. Is that something you would plan to move forward by yourself if that data looks good?

Speaker 5

And then 3rd, you noted in terms of kind of the expanded cash runway and opportunity potentially to expand the pipeline. I guess, is that a near term priority? And I guess, what stage of development would you be looking for in terms of assets? Thanks.

Speaker 2

Yes. Hi, Derek. Hey, thanks for the questions. There's a lot in there. So I'm going to take them in order.

Speaker 2

Maybe to start with, Izzo, right, and the partnering question and then what are we going to do with UB or how do we think about Uveitis. What I'd say with respect to partnering and this is what we've been saying, we're going to do what's best for the program, right? We're open to all options. And fundamentally, we want to see, HS and PSA, right, bring benefit to patients and that might be with a larger organization that has existing capabilities and infrastructure, right. So again, we'll do we'll look at all the options and we'll do what's best for program.

Speaker 2

I do want to note and reemphasize something that Gil said, which is we have not included any financing proceeds or proceeds from a partnership in our cash runway guidance, right? So that excludes any contribution from a potential partnership. So I think that's the response IZO and uveitis questions. With respect to potential BD going forward, look, I mean, we are always going to look at opportunities. We'll be opportunistic.

Speaker 2

And as Gil said, we have assumed, right, that there could be some pipeline expansion and we have the funding for that we believe, right? I would say that right now, it's important for us to focus on lonaglumab and high quality execution on that program and that is the focus for now. And so, any right? But we certainly will consider any opportun right? But we certainly will consider any opportunistic opportunities, right, over time.

Speaker 2

And then I think you had questions around the design, right, of the lonagutumab development program. And maybe it's helpful to frame that up a little bit, Right, just stepping back, we have spent the last few months evaluating the entire development program really with 2 goals. One is how do we de risk the Phase 3 program, right? And the other is can we do that at the same time as we try to accelerate the program? And we have been trying to balance both of those things.

Speaker 2

We do think that adding this additional dose cohort into the Phase 2 program helps us achieve that. 1st, it allows us to complete dose exploration in the Phase 2 trial rather than in a 2b3 as originally planned. And what that does is it allows us to move directly into a Phase III program and potentially run 2 Phase III trials concurrently, right, rather than sequentially, which obviously has the potential to accelerate that program. And we've added the 70 mg dose. We are looking at it in both 3 weeks, right, and 4 weeks, right, to confirm the dose that we're going to take into the pivotal program.

Speaker 2

I would say, I think it's important to note, we think we have our dose, right? But regimen is also important. And again, we want confidence around that dose we take into the program and the ability to do that in the Phase 2, right, is we think potentially both derisking and hopefully does allow us to go more quickly into that Phase 3 program.

Speaker 5

Understood. I guess just a follow-up there in terms of like again, is that being examined for a potential loading dose or is the loading dose going to be figured into the Phase 3 program?

Speaker 2

No. I mean, that's not something we're contemplating now. I mean, we do think the 70 is our dose.

Speaker 5

Understood. Thank you.

Speaker 2

Thanks, Eric.

Operator

Thank you. Our next question comes from the line of Tyler Van Buren with TD Cowen. Please proceed.

Speaker 6

Hey guys, thanks for the updates. It's encouraging to see the rationalization of the pipeline. I want to ask about the Phase 3 uveitis trial readout. So what would compelling data from that trial look like later this year that would lead you to pursue another trial for registration? And the second question is, what are your latest thoughts on the market size for uveitis?

Speaker 2

Yes. So maybe I'll start and then I'll turn it over to the team. I mean, I think we're going to evaluate uveitis in the same way that we have all of our other programs, right? We're going to look at the totality of the data, the market, the unmet need. What I would say maybe to start is there is very high unmet need, right, in uveitis.

Speaker 2

And so we like that opportunity, right, to address the unmet needs of patients. There is obviously very limited there are very limited options for those patients and that will also factor into it. In terms of the trial design and sort of what are the endpoints, I'll turn it over to Shaf maybe to just walk you through that.

Speaker 3

Yes. No, thanks Mina. Our trial is designed the same as the Umera trial, which is the only large Phase 3 study that was done in uveitis. We have patients receiving steroids at best line and then having a regimen to decrease them over 15 weeks. And we have a primary EFCAS endpoint at week 24, where we'll be looking at 4 parameters, same as Yumira did, looking at inflammation in the back of the eye, chorioretinal inflammation and then looking at inflammation within the eye, looking at the vitreous, haze, anterior chamber as well and then best corrected visual acuity.

Speaker 3

So that's the treatment failure. So we'll be looking at a compelling data set that showcases there are more patients on placebo versus drug that achieve this endpoint.

Operator

Tyler?

Speaker 6

Yes, all good. Thank you.

Operator

Thank you. One moment for our next question. And our next question comes from the line of Yasmeen Rahimi with Piper Sandler. Please proceed.

Speaker 7

Thank you

Speaker 8

so much team for sharing these difficult decisions with us and walking us through the rationale. Team, I guess, could you maybe talk about cohort 3, cohort 4 has just begun. At what junction, what have you seen from that dose cohort so far? When should we be expecting data from it? And then, I guess, and then as we think about Phase 3 design, just maybe parts of the you alluded to some innovative approaches, but maybe walk us through who would be the ideal patient.

Speaker 8

It also seems like test studies have become quite competitive in terms of enrollment. So appreciate also color ensuring being able to deliver top line data in an efficient manner. Sorry, there was too many questions in there, but I guess cohort 3 and yes. I appreciate color on that. Thank you.

Speaker 8

Sorry about that.

Speaker 2

No, for sure. So let's start with Cohort 3 and then, if we miss anything, just remind us, just prompt us. Like I just said in our prepared remarks, we are thinking about that Phase 2 program, right, holistically. We think it's most useful to read out the data from that Phase 2 program after we've met with the FDA later this year, right, when we can give a more complete picture. And that more complete picture would be additional data, right, including from Cohort 3, really from the totality of that across the Phase 2 program and also how we're thinking about the Phase 3 program.

Speaker 2

So I think that's a little bit of the timing and we would expect that to be later this year or potentially early next year, right, but really when we've got a more complete picture to share with you all. We think that that's most useful. So I think that's kind of the design. In terms of the patients that we can potentially serve, we do think that there continues to be very high unmet need, right, in TED patients. And I think we talked about this before, we are particularly interested in the ability to think about chronic dosing, right?

Speaker 2

This is a disease that can flare or regress or however you want to describe that. And there is an ongoing need for those patients, right, across many different endpoints. And so we really want to optimize sort of the dose and the regimen, right, to try to address the totality of the disease. So we think that there, again, continues to be unmet need and we are very interested in exploring that chronic

Speaker 8

population. Thank you.

Speaker 2

What did I miss?

Speaker 8

Yes. No, no, no. Just, yes, that's an enrollment timing just because it's competitive. Like, we feel confident to, to just because now several test studies will be ongoing concurrently in Phase 3. Appreciate some color there.

Speaker 2

Yes. And look, we feel good about that. I mean, obviously, we're enrolling patients right now, right, into the Phase 2. And we think that that's we feel good about that experience and confident going into the Phase 3 trial, somewhat based on that experience. So understand that there are more trials going on, but we feel good about that.

Speaker 8

Thank you so much. I'll jump back in the queue.

Operator

Thank you. Our next question comes from the line of Akash Tewari with Jefferies. Please proceed.

Speaker 7

Hi, this is Phoebe on for Akash. Thank you for taking our question. So I guess more on uveitis, are you targeting more refractory patients like those who are on or after prior biologic use? And additionally, will UBI just be considered an orphan indication and could you potentially get orphan pricing of around $200,000 per year in this indication? I imagine there might be some pushback from payers for orphan drug pricing given HUMIRA is already approved for uveitis and is much cheaper.

Speaker 7

So just some color around that would be helpful.

Speaker 4

Yes, great. Thanks for the question. This is Gil. As Mina was saying earlier, this is an interesting indication. There's still a very high unmet need.

Speaker 4

There's really only a couple of treatment options, essentially steroids and Humira. And the current standard of care is really only modestly effective. So we really think there's an opportunity here to drive additional benefits to patients whether that at any line of this. We also think that with the limited therapeutic options as a therapy like Iso may come in here, they'll also have an opportunity to expand the market and diagnosis of this condition. I think in terms of the pricing question, that's a little early to say, but certainly something that we think about as we go in, but it's a little early to speculate on pricing in the indication.

Speaker 3

Yes. And on patients that are coming in the study, these are patients with active non infectious UBI active. There will be patients who also have been previously exposed to other biologics except those biologics that are on the IL-seventeen pathway.

Speaker 7

Understood. Thank you.

Operator

Thank you. Our next question comes from the line of Emily Bottnor with H. C. Wainwright. Please proceed.

Speaker 7

Hi. Thanks for taking the questions. I guess, just kind of a clarifying question. In the 70 mgLAWNI dose, are you enrolling 8 patients in total across the 3 weekly and 4 weekly regimens or is it 8 per regimen? And then kind of follow-up to that, do you think that's a sufficient number of patients to kind of get an idea if that's the appropriate dose to take into Phase 3?

Speaker 7

And then lastly, if you can kind of confirm that you haven't seen any cases of hearing impacts from any of the cohorts so far? Thank you.

Speaker 2

Yes. Thanks. Let me start and maybe I'll turn it over to Shep on the hearing. The way that this final cohort is set up, it has 8 patients and allows us to try the 70 mgs Q3 and Q4. It also gives us the flexibility to go up to 16 patients in that cohort.

Speaker 2

So it is built with some flexibility. Obviously, those are small numbers, but in totality, right across this Phase 2 program, right, we will have seen inpatient data across multiple doses and regimens and we think that that's going to be very again useful for us in a way to derisk that Phase 3 program, right? And maybe I'll let Chet address the hearing question.

Speaker 3

Yes. No, thanks for that response. And for hearing, all our dose groups that we have been exploring in the dose range have audiograms done at baseline and throughout the course of the study. None of the patients in any of the dose groups have developed any notable hearing impairment or sensorineural hearing loss. We did report in March in our top line data that there were 3 patients in one of the cohorts that hit transient tinnitus that resolved and none of those patients had changes in audiogram.

Speaker 3

So, so far, no major changes pertaining to audiogram changes in all of our cohort.

Speaker 7

Okay, great. Thanks for taking the questions. Thank you.

Operator

Thank you. Our next question comes from the line of Vikram Purohit with Morgan Stanley. Please proceed.

Speaker 9

Hi, good afternoon. Thank you for taking our questions. We had 2. So first on 517, I was just curious what you might have seen in the early stage of development for that molecule to decide to stop pursuing that any further? And then secondly, for the end of Phase 2 meeting with the FDA, just curious, what are the main questions you're hoping to have answered about the Phase 2 development program through that meeting with the agency?

Speaker 9

Thanks.

Speaker 2

Yes. Maybe I'll start with 517. As I said on the call, we did do a healthy volunteer study. And actually, some of that data is up on our website if you want to take a look at that. I think really we made again a strategic sort of prioritization decision and a program decision and so that's we are not going to continue development of that program internally.

Speaker 2

But if you do want to see the data, it is up on the website. Okay. And then I guess on the second question with respect to the end of Phase 2 meeting, maybe I'll turn that over to Shah.

Speaker 3

Yes. No, thank you for that question. Our end of Phase 2 meeting is principally a traditional end of Phase 2, where we would sit with the regulator FDA to explore what we have done to date and agree on the benefit risks that we are showcasing as was discussed dose and obviously importantly, the study designs will be at that point in time wanting to proceed within Phase 3.

Speaker 9

Understood. Thank you. And then a quick follow-up then. Just apologies if this was discussed and we missed it, but the cash runway guidance through 20 27, exactly what does that contemplate with regards to future development in uveitis?

Speaker 4

Yes. So the cash runway guidance, Vikram, we have included the completion of the ongoing uveitis study as well as the HS and PSA. We have included the completion of the Phase 2 program in Lonagutinib. 2 Phase 3 programs 2 Phase 3 trials in the registrational program for Lonagutinib as well as potential BLA enabling activities.

Speaker 9

Okay, understood. Thank you.

Operator

Thank you. And our last question is coming from the line of Samantha Simenkov with Citi. Please proceed.

Speaker 7

Hi, good afternoon and thanks for taking the questions. I just have a couple on Lonnie. I see in your corporate deck you have I think what's maybe a new slide, just a bit more detail on the tinnitus that you've seen. And you've observed all three cases from just cohort 1. So the question is, why you think this might be the case?

Speaker 7

Why is it only in cohort 1 and none is the cohort 2 patients so far? Is there something common between these three patients? Or is perhaps the loading strategy, loading dose strategy exploring cohort 2? Do you think that's driving the distance the difference? Love any thoughts you could provide there.

Speaker 2

Yes. Look, maybe I would just start with what we are showing is what we saw in Cohort 2. And I would note that there were none in Cohort 1, sorry, there were none in Cohort 2. And then maybe I will turn it over to Shep for some more detail.

Speaker 3

Yes. No, thanks for the question Samantha. Number 1, we have not seen any reason why these patients are tinnitus in that cohort. If you specifically look at the narratives for each respective patient, you will notice that this was tinnitus that was transient in the majority of those 3 patients and resolved. If anything, I can comment on one of the patients who had tinnitus at 24 hours after the first injection and 24 hours it resolved and it happened the same.

Speaker 3

Remember cohort 1 only had 2 injections at week 0 week 3. So no relationship to any aspect pertaining to the patient characteristics. And I think not seeing anything in Cohort 2 gave us the confidence that this is not related to any dose exposure. And therefore, this was just something that happened within the study. And as I mentioned, all patients are having audiograms at baseline over time and to date we have not seen anything that speaks to CINTAINURA hearing loss or impairment.

Speaker 7

Great. Thanks so much for taking the question.

Operator

Thank you. And with no further questions in the queue, I will turn it back to Tyler Marciniak for his concluding comments.
