Stoke Therapeutics (NASDAQ:STOK), headquartered in Bedford, Massachusetts, is a clinical-stage biopharmaceutical company focused on developing genetic medicines to upregulate protein production for the treatment of rare neuromuscular and neurological disorders. Founded in 2014, the company applies its proprietary Targeted Augmentation of Nuclear Gene Output (TANGO™) platform to design antisense oligonucleotides that selectively modulate RNA splicing and enhance expression of functional proteins.

The company’s lead program, STK-001, is an antisense oligonucleotide therapy designed to increase production of the sodium channel protein SCN1A and is currently in clinical development for Dravet syndrome, a severe childhood-onset epilepsy. In addition to STK-001, Stoke is advancing STK-002, its preclinical candidate for spinocerebellar ataxia type 6 (SCA6), along with other discovery-stage programs targeting genetic diseases characterized by insufficient protein levels. Stoke’s approach aims to address the underlying genetic deficiency rather than solely treating symptoms, positioning its pipeline to potentially benefit a range of patient populations with high unmet medical needs.

Since going public on the Nasdaq exchange in early 2020, Stoke Therapeutics has grown its research capabilities and established strategic collaborations to support its development efforts. The company’s leadership team brings together expertise in molecular biology, neurology and clinical development, guiding Stoke’s mission to translate its TANGO platform into transformative therapies. Stoke serves patient communities and clinical partners globally, with ongoing and planned trials conducted across North America and Europe.

Hello, and welcome to the Stoke Therapeutics Second Quarter 2026 Business and Financial Update. At this time, all participants are in a listen-only mode. After the speaker presentation, there will be a question and answer session. To ask a question during the session, you will need to press star one one on your telephone. You will then hear an automated message advising your hand has been raised. To withdraw your question, please press star one one again. Please be advised that today's conference is being recorded. It is now my pleasure to introduce CFO Thomas Leggett.

[Thomas Leggett, CFO at Stoke Therapeutics]

Good evening, and welcome to Stoke Therapeutics Second Quarter 2026 Business Update Conference Call. I'm Thomas Leggett, the Chief Financial Officer of Stoke Therapeutics. Joining me on today's call are Ian Smith, our Chief Executive Officer, Dr. Barry Ticho, Chief Medical Officer, and Jason Hoitt, Chief Patient Officer. As a reminder, today's webcast presentation is available in the investors section of our website. This webcast is being recorded and will be available for replay later this evening. Before we begin, please note that today's discussion includes forward-looking statements. These forward-looking statements are subject to risks and uncertainties, and actual results may differ materially. Please refer to our filings with the SEC for additional information. On today's call, we will review recent progress across the breadth of our business. Ian will start with an overview and share an update on the ongoing phase III EMPEROR study.

[Thomas Leggett, CFO at Stoke Therapeutics]

This study is progressing nicely toward a data readout in the third quarter of 2027. Barry will then provide additional detail on EMPEROR and our longitudinal data set from our ongoing open label extension studies, also known as our OLEs. He will also review the advancement of other pipeline opportunities that we are progressing, including our investigational medicine for autosomal dominant optic atrophy, or ADOA. We'll then hear from Jason on our commercial planning activities to deliver zorevunersen to all patients who may benefit in the U.S. following a potential FDA approval by early 2028. I will review our financials and specifically the strength of our balance sheet, and then we will open for Q&A. I will now hand the call over to Ian.

[Ian Smith, CEO at Stoke Therapeutics]

Thank you, Tommy, and thank you to those joining us on the call tonight. Starting with our phase III EMPEROR study. The recent completion of enrollment of 162 patients in just 10 months speaks to the awareness and enthusiasm of zorevunersen and its potential to change the course of Dravet syndrome by addressing the underlying genetic cause of this disease. Patients in the study are advancing through key study milestones, and importantly, there have been no treatment discontinuations. We are now within a year of our phase III readout to data that would support the completion of our NDA. We continue our discussions with the FDA and have scheduled a pre-NDA meeting later this year as we prepare to initiate our rolling NDA submission in the first quarter of 2027.

[Ian Smith, CEO at Stoke Therapeutics]

The meeting will focus on further educating the agency on the long-term safety and efficacy of zorevunersen using prior and ongoing analyses from our phase I, II and OLE studies. We'll also cover the details of our NDA submission, including the data to be included, the statistical analysis plan, and the timing of each module. Beyond Dravet, we have a unique opportunity with our platform in additional disease areas. We continue to advance STK-002, our investigational medicine for ADOA. Our phase I study recently completed dosing of the first cohort of patients, and we have moved into a higher dose in a second cohort of patients. While continuing our work in SYNGAP1-related disorders, we are also expanding our early research efforts with new targets in haploinsufficient diseases, mainly focused in CNS, given our expertise in the field.

[Ian Smith, CEO at Stoke Therapeutics]

Consistent with our investment in other pipeline opportunities, in July, we strengthened our leadership team with the addition of Tom McCauley, our Chief Scientific Officer, who will help guide the next phase of platform expansion and translational research. From financial perspective, our business investment is well supported by our pro forma cash position of approximately $420 million, providing a runway through to potential U.S. launch of zorevunersen by early 2028. We have entered a period where execution is increasingly important, and we remain focused on delivering the data and completing the regulatory and commercial readiness activities necessary to bring zorevunersen to patients as quickly as possible. With that, I now pass you to Barry, who can provide more detail as to our progress.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

Thank you, Ian. Tonight, I will start with an update on the progress with the EMPEROR study. EMPEROR is a global, double-blind, sham-controlled phase III study of zorevunersen in patients with Dravet syndrome. In June, we announced completion of enrollment of 162 patients into EMPEROR. This puts us on track for our phase III readout in the third quarter of 2027. Data from these patients are expected to be the final data necessary to complete our rolling U.S. NDA submission, which we expect to submit in the second half of next year. As Ian mentioned, the study is progressing well. To date, more than 140 patients are through week eight of the study and therefore have received either the two loading doses of 70 mg of zorevunersen or sham. More than half of patients have only one dose left in the 52-week treatment period.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

Approximately 60 of these patients have also completed their week 28 visit. The time point at which the primary endpoint of percent change in major motor seizure frequency is measured. The study will remain blinded through 52 weeks, given the key secondary endpoints measuring cognition and behavior will be assessed at that point in time. In a couple of weeks, the first patients in the study will reach that milestone and have the opportunity to progress into treatment extension beyond week 52. Thus far, no patients have discontinued treatment in EMPEROR. When we designed EMPEROR, we made several assumptions that are relevant when evaluating the study's statistical powering. EMPEROR was powered to detect statistically significant effects on the secondary endpoint, measuring improvements in cognition and behavior. This resulted in substantial powering for the primary endpoint.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

Second, the study design assumed a certain percentage of patient discontinuation, and as previously mentioned, we have had no discontinuations to date. Our enrollment target was at least 150 patients, and we ultimately enrolled 162 in our primary analysis population. All of this reinforces our confidence in the study powering and the overall likelihood of demonstrating statistically significant effects on the primary and key secondary endpoints. Beyond the 162 patients intended to support our NDA, an additional cohort of approximately 30 patients in Europe is expected to complete enrollment this month. Planning is also underway for a new study of zorevunersen in infants and toddlers under 24 months of age. We expect that study to initiate later this year to support our goal of enabling early intervention with this potentially disease-modifying therapy.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

Earlier this year, we presented data out to four years from our OLE study, which I'll briefly review this evening. I'll begin with our data on seizure frequency reduction. Here we see four years of data in which all patients received treatment with zorevunersen. These effects are demonstrated on top of the standard of care anti-seizure medicine patients were already taking. These data include all patients across dose levels, including various levels of loading doses evaluated in the first year of treatment in the phase I/II study, as well as various levels of maintenance doses used in the OLE study. The orange line most closely reflects our phase III dose regimen. The blue line is patients who received a variety of doses during the phase I/II and OLE.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

By month 29, all of them had transitioned to receiving 45 mg every four months, which is consistent with the anticipated commercial regimen pending the results of EMPEROR. While durable seizure control is the most immediate and obvious clinical need, we know that Dravet syndrome is not only a seizure disorder. It is a severe neurodevelopmental disease in which children develop normally till approximately 24 months of age, when they begin to stagnate in development with minimal improvements in skills and activities such as communication, interpersonal skills, and mobility. This means that regardless of chronological age, gains in cognition, behavior, and daily function are meaningful. To evaluate potential gains in cognition and behavior, we use Vineland-3, a standardized assessment of adaptive functioning. Here are the four-year Vineland data from our ongoing OLE study.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

These data demonstrate statistically significant improvements in cognition and behavior each year through four years of treatment compared to the OLE baseline. Similar to the seizure data I just showed, these OLE data include patients across all dosing regimens evaluated in our phase I/II study, including loading doses that were lower than the two 70 mg doses we are evaluating in our phase III study. Importantly, all improvements in Vineland scores shown here are measured against patients' baseline scores when they entered the OLE study, and therefore do not capture any benefit that may have been observed during the earlier phase I/II treatment period. Alongside these efficacy findings, we continue to build a long-term safety data set for zorevunersen. Of the 81 patients enrolled in our phase I/II-A study, 93%, or 75 patients, continued treatment in the OLE study. Of those, 57 patients remain in these studies.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

More than 930 doses of zorevunersen have been administered to date, with some patients receiving treatment for more than five years. Overall, no new safety findings have emerged, and zorevunersen continues to be generally well-tolerated. The phase I/II and OLE safety and efficacy data provide a substantial data set that support the design of our phase III EMPEROR study and also a detailed understanding of the benefits to patients and how this potential medicine could change the course of Dravet syndrome for patients and their families. These long-term longitudinal data, which include patients who have received up to 16 doses over a five-year period, offer insight into the ongoing benefits with chronic dosing. Analyses from this clinical data set have been well-received at major medical conferences and were published earlier this year in "The New England Journal of Medicine."

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

Our educational efforts will continue throughout the rest of 2026 and into 2027 with new analyses, including effects on seizure severity, improvements in seizure freedom, and quality of life. We'll also continue to share these insights with the FDA. The data generated to date and successful advancement of zorevunersen in EMPEROR reinforce our belief in the potential of our platform to address the underlying cause of a number of severe genetic diseases. We are particularly focused on diseases caused by haploinsufficiency, where we believe we have a unique opportunity to use our proprietary scientific approach to restore protein expression from the healthy copy of a gene. In the near term, we are advancing STK-002, our investigational medicine for ADOA. ADOA is a progressive genetic disease that leads to degeneration of the optic nerve and loss of vision starting in the first decade of life.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

It is the most common inherited optic nerve disorder. The majority of cases are caused by mutations in one allele of the OPA1 gene, resulting in haploinsufficiency or 50% of the OPA1 protein. There are currently no approved treatments for ADOA. STK-002 is designed to increase OPA1 protein expression with the aim to improve vision in people with ADOA. Phase I dose escalation study is ongoing in the U.K. and Europe, and recently completed dosing of the first cohort of three patients. Dosing for our second cohort is scheduled to begin this week, with the third and fourth dose cohorts to follow, subject to ongoing safety assessment. We anticipate early safety and efficacy results in the first half of next year to guide our next steps for development.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

We are encouraged by our preclinical data as well as emerging data from the field, demonstrating that upregulation of OPA1 protein has disease-modifying potential. We look forward to sharing additional updates as the program advances. With that, I will turn the call over to Jason.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

Thank you, Barry. Today, I'll focus on three areas: the market opportunity in Dravet syndrome, how we think about label and access, and the progress we're making toward a potential U.S. launch. I'll start with the patient population. There are an estimated 38,000 patients with Dravet syndrome across the seven major markets where we're running the EMPEROR study, the U.S., U.K., EU4, and Japan, including approximately 16,000 in the U.S. alone. Our estimates are based on an epidemiology analysis that scaled annual incidence to prevalence using country-specific live birth rates over the past 85 years that was then adjusted for Dravet-specific mortality. In the U.S., the Dravet population is highly concentrated around centers of excellence and other key treatment centers. Approximately 50% of identified U.S. patients are cared for by the top 50 sites. All 50 of those sites are experienced in administering intrathecal medicines.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

Half of them are already participating in a zorevunersen trial. This provides a strong foundation for early adoption and allows us the ability to maximize this opportunity with a lean commercial infrastructure, including approximately 25 sales representatives who will build upon our long-standing relationships with treating physicians established by our medical affairs teams. We're confident we know where 70%-80% of the patients 25 and younger are being cared for today. Out of the estimated 16,000 total U.S. patients, we estimate 6,000 are under the age of 25 and likely under the care of a pediatric provider. These are patients who would be immediately addressable at the time of potential U.S. launch. Pediatric neurologists and epileptologists tend to develop strong and lasting relationships with patients and families and therefore continue to care for them well into early adulthood.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

As such, this group of clinicians follow the field closely and are typically the most well-informed about the disease and current treatment options. In addition, an ICD 10 code was established in 2020 and is used to track confirmed Dravet diagnoses. These data provide support for our assumptions as well as insight into where patients are in their diagnosis and treatment journey, along with the providers who care for them. We believe diagnosis rates will increase over time as zorevunersen and other genetically targeted treatments continue to advance. We will continue to invest in targeted disease awareness and educational efforts to emphasize the importance of genetic testing to confirm a Dravet diagnosis. Looking ahead to our NDA submission, product labeling, and patient access, we continue to believe that the totality of evidence generated for zorevunersen supports a differentiated value proposition in Dravet syndrome.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

By the time of our NDA submission, we expect to have approximately six years of safety and efficacy data available from our phase I, phase II, and OLE studies, providing insight into the durability of treatment effects and the potential for disease modification over time. We intend to incorporate these data into our NDA submission for inclusion in the label. FDA guidance is clear that in addition to pivotal study data, clinical study data that provide important information about a drug's effectiveness and that would be useful to practitioners in their clinical decision-making should be included in the label. We believe that the longitudinal data from our OLEs are relevant within that framework. We know from market research that payers and healthcare providers already consider these data to be the most compelling evidence that we may have at the time of a potential approval.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

As Ian mentioned, we have a pre-NDA meeting with the FDA later this year. We plan to initiate the NDA in the first quarter of 2027, beginning with our chemistry, manufacturing, and controls module. We recently completed commercial-scale manufacturing validation for both drug substance and drug product and are currently finalizing product specifications. We continue to expect that if approved, zorevunersen would be granted a broad label for the treatment of Dravet syndrome, consistent with our breakthrough therapy designation. This broad label, combined with the existing concentration of Dravet providers and well-established infrastructure for administering intrathecal therapies, positions us for a smooth and efficient adoption with a lean commercial infrastructure at the time of launch. While we remain focused on accelerating access in our commercial territories in North America, our partners at Biogen are focused on expediting access in countries around the rest of the world.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

In addition, we plan to initiate a study of zorevunersen in the adult population by the end of this year. This study is intended to expand clinician conviction for zorevunersen in adults and support access among adults living with Dravet. Taken together, the strength of the clinical package, the continued positive feedback from payers and providers, and the progress we're making across commercial readiness activities give us confidence in our preparations for a potential U.S. launch in early 2028. With that, I'll turn the call over to Thomas.

[Thomas Leggett, CFO at Stoke Therapeutics]

Thank you, Jason. I'll remind you that full financial results can be found in our 10-Q. Today, I'll focus on the strength of our balance sheet position. We ended the quarter with $354.3 million in cash equivalents, and marketable securities. Shortly after the close of the quarter, we raised an additional $65.7 million in net proceeds through our ATM program, selling approximately 2.1 million shares of common stock to a high-quality, long-only fundamental investor. This resulted in a pro forma cash position of approximately $420 million. Along with the reimbursement we received from Biogen for zorevunersen-related expenses and a potential development milestone payment, we expect our cash position to fund our operations through a potential U.S. launch in early 2028.

[Thomas Leggett, CFO at Stoke Therapeutics]

In terms of our priorities, we continue to invest in advancing our phase III study and preparing the organization for potential U.S. commercialization, while progressing our pipeline and maintaining a strong financial position. Thank you. I will now ask the line to be open for Q&A.

[Operator]

Certainly. 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. One moment, please. Our first question comes from the line of Andrew Tsai with Jefferies.

[Andrew Tsai, Managing Director at Jefferies]

Hey, good afternoon. Thanks for taking our questions. The first one is, you guys have provided a lot of nice numbers this quarter where patients are exactly in the EMPEROR study. Maybe bigger picture, what should we be taking away on these various data points as we track study progress and await the phase III timelines? Secondly, it sounds like you have this pre-NDA meeting with the FDA in the second half, in part to talk about the SAP plan for EMPEROR. May I ask what you guys are hoping to get alignment on? Is it kind of confirming the hierarchy of the five sub-domains of Vineland-3, maybe confirming which ones need to be stat sig for you to file? Just a little bit more color would be helpful. Thank you.

[Ian Smith, CEO at Stoke Therapeutics]

Andrew, this is Ian, thanks for the question. Good to chat to you again. We did provide a lot of, as you put it, nice numbers on the call. I'm going to ask Barry to reiterate those. There were a lot of them. There are metrics internally of how we measure the trial every single week. They're very important to us in terms of measuring the progress of the trial. Barry, why don't you provide those numbers again, then I'll take the discussion on the NDA.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

Sure. Thanks, Ian, and thanks, Andrew, for the question. The study is progressing quite well, patients are going through trial milestones. Again, as we said, enrollment is complete, we enrolled 162 patients in the study. Of those, 145 patients are through their week eight, which means they've received two loading doses of the 70 mg or sham treatment. About half of the patients have gone through week 24, they have only one dose left in their 52-week treatment period. Importantly, 60 patients have completed week 28 visit, that means that they have hit the time point of the primary endpoint, which is seizure frequency. We're also very pleased that very soon patients will start to be reaching their week 52 endpoint, which is the important part of the treatment period study. Again, no patients dropped out of the study, which is important.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

This progress gives us a lot of confidence in EMPEROR to date and is consistent with the data that we've had from the OLE studies as well as our phase I/II data.

[Ian Smith, CEO at Stoke Therapeutics]

Thanks for that, Barry. I'll just reiterate the data that we're seeing in terms of no discontinuations with given the large number of progress of these patients through the study continues to emphasize that this medicine is generally well-tolerated. That's also consistent with the five-year data we have from the phase I/II and the OLE, where we've dosed between 70 and 80 patients and continue to show that the medicine is generally well-tolerated. To your second question, Andrew, about the pre-NDA meeting, I'll kind of answer it in a bigger way and tell you all about the meeting. Firstly, the meeting will occur in early fourth, so not too far away. This is ordinary course when you're at this stage of phase III development, when you're in registration studies. We're going down to the FDA with three objectives or three topics.

[Ian Smith, CEO at Stoke Therapeutics]

The first being to discuss the sequence of submission of data for our rolling submission. We anticipate initiating a rolling submission in Q1 of 2027, that would start with the CMC package, followed by the preclinical data, then closing out that rolling submission in the third quarter of 2027 with the clinical data. That's the first piece. Second, as you point out, it is the SAP, the statistical analysis plan. Again, this is normal practice. Before you get to the end of your phase III and certainly during your phase III, you don't want to leave it too late. Need to go down the line on the details of the SAP. The way that our protocol has currently been constructed is that our primary endpoint is not in discussion in terms of the detail, but we will talk about the secondary endpoints.

[Ian Smith, CEO at Stoke Therapeutics]

The way that the study protocol has been described so far is that we will look at the secondary endpoints in either a hierarchical analysis, that means taking individual Vineland domains in a hierarchical manner. Or we will look at it in a composite basis, where you combine those individual Vineland domains. The study is designed, we've communicated that it is designed in terms of collecting both sets of data. What we want to do is we want to go to the FDA and discuss exactly how they would like us to present that data. I will just point out that the first, in terms of the hierarchical secondary endpoints, the first hierarchical secondary endpoint is actually continued seizure reduction. I'll just point that out. It goes into the Vineland domains. The third topic is the OLE data.

[Ian Smith, CEO at Stoke Therapeutics]

As you know, each year we've gone down to the FDA and discussed the OLE data. Last year we were discussing it with the FDA in the latter part of 2025. This year we have the access to the four-year data being updated from last year's three-year, and we're going to discuss that again. Why are we doing that? Because it's the importance of that data to show this is a drug that is a chronically administered drug, and this data has now been administered in patients for up to a period of five years. We've been able to measure both durable seizure reduction and the continued improvement each year of Vineland scores, which are just a measure of skill and task acquisition of these children that unfortunately have a, we call it a Dravet age of approximately 24 months.

[Ian Smith, CEO at Stoke Therapeutics]

We're potentially providing them task acquisition and skill acquisition that then is more typical or neurotypical of the children that have a greater age and are healthy. The importance of that data, obviously we've just discussed before, is it does help us understand the effectiveness of the medicine, as Jason has described in his remarks, and will continue to be part of the NDA submission when we file our clinical data around the middle of next year.

[Andrew Tsai, Managing Director at Jefferies]

Thank you. Very clear.

[Operator]

Thank you. Our next question comes from the line of Alyssa Larios with Leerink Partners.

[Alyssa Larios, Equity Research Associate at Leerink Partners]

Hi, good evening, everyone. This is Alyssa on for Marc Goodman. I was just wondering if you could walk us through what parts of the NDA you expect to submit starting in Q1, and what will still be left once the EMPEROR data come in. Thank you.

[Ian Smith, CEO at Stoke Therapeutics]

Alyssa, sorry. You didn't come through.

[Alyssa Larios, Equity Research Associate at Leerink Partners]

What's the last piece?

[Ian Smith, CEO at Stoke Therapeutics]

You're asking about the sequence of the NDA submission?

[Operator]

Order.

[Ian Smith, CEO at Stoke Therapeutics]

Yeah, sorry. You just didn't come through, Alyssa. There is some background noise. As I just mentioned, we anticipate starting our rolling submission in Q1 of 2027. That will initiate with the filing of our CMC package. Jason had a number of comments in his prepared remarks where we have made great progress in that area, including quality. That will be the initiation of the submission in Q1 of 2027. The final part of the submission will be clinical data, which will occur in Q3 of 2027. That data will conclude with the week 52 secondary endpoint measurements to complete that submission in Q3 of 2027.

[Alyssa Larios, Equity Research Associate at Leerink Partners]

Okay. Thank you very much.

[Operator]

Thank you. Our next question comes from the line of Pete Stavropoulos with Cantor.

[Pete Stavropoulos, Director of Biotech Equity Research at Cantor]

Hello, Ian and team. Thanks for taking our questions. First question that I have is going back to the Vineland-3 sub-domains for the phase III readout. What gives you confidence that one year time point is sufficient to sort of see separation between the active arm and sham for the secondaries? The second question I have is one point of discussion has been potential pricing of zorevunersen if approved, specifically around data what data may be needed to translate to a label that suggests or states disease modification that will ultimately impact pricing. Can you just provide your thoughts and plans and possible scenarios for getting disease-modifying outcomes into the label? If achieved, how should we be thinking about pricing?

[Ian Smith, CEO at Stoke Therapeutics]

Yeah. Thanks, Pete. Number of questions there. Maybe start with asking Barry to help you understand the powering of the study. I'll then talk about the data we have that informed us and support our confidence that achieving both primary and secondary endpoints. I'll ask Jason to comment on the work we've been doing, which is extensive, to understand the value of the medicine, AKA pricing.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

Yeah, thanks. The powering of the study then was based on our phase I/II and OLE data. The confidence that we have in showing a difference from sham based on the fact that the secondary endpoint, the Vineland endpoints, are powered at 90% or greater than 90% to show a 0.01 or less P value. Those are results that were based on 150 patients enrolling in the study. As we mentioned, we now have 162. That increases our confidence that we'll be able to show a significant difference from sham in this study.

[Ian Smith, CEO at Stoke Therapeutics]

Yeah, thanks, Barry. I'll just pick up from where Barry mentioned. I would say increasing confidence with the 162 versus the initial powering calculations of 150. What I would also add is in that 150, that was the initial powering assumption. It did also assume a 15% discontinuation rate in that phase III. As Barry mentioned in his prepared remarks, we have seen zero discontinuations to date in the study. If you work the analysis back, it was powered, as Barry says, to a 90% confidence level for a P value of 0.01 to the secondary endpoints from approximately 125-30 evaluable patients. At this point in time, we have 162 enrolled still in the study and zero discontinuations. The data that we used to power the study frankly, was data from the phase I/II and the OLE data.

[Ian Smith, CEO at Stoke Therapeutics]

Notably, you asked about the confidence, Pete, and this time last year we provided data to help understand the impact of a regimen that had similar dosing to that in our phase III study. That data was provided at EPNS last year. I believe we showed it on our Q2 conference call. If not, there was a disclosure that was very close to August of 2025. That data showed that in Vineland scores for the five key domains that we've been discussing, showed Vineland scores of between eight and 11 in terms of Vineland scores of each of those domains. I would just point out that our phase III study secondaries are powered for a two-three-point delta in Vineland scores.

[Ian Smith, CEO at Stoke Therapeutics]

We have high confidence of hitting these secondary endpoints given the data that we have both from the phase I/II and the OLEs, and in particular that dosing regimen that is consistent with the phase III dosing regimen of two 70 mg doses and two 45 mg doses which accumulates to approximately 230 mg of dosing.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

On your last question, Pete, around pricing and the implications around pricing, it is timely that you asked the question because just earlier this year we conducted some pretty extensive market research across our constituent audiences including healthcare providers, payers, caregivers, et cetera. Specific to the healthcare providers and payers, we wanted to understand the potential implications of different label scenarios and how those audiences think about the data that are included in the label versus other data that may be available and in the public domain, published, presented at scientific conferences, et cetera. I think the long and short of it is that the data to be included in the label are going to be most important for promotional purposes, right? How our commercial teams are able to educate healthcare providers on the efficacy and safety of zorevunersen at the time of approval.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

When we ask those two audiences, both payers and healthcare providers, talking about the different potential scenarios, what could be and would be the most compelling pieces of evidence that they would have at their disposal to drive, in the case of healthcare providers prescribing for their patients and in the case of payers, medical policies that support reimbursement for a broad population of patients with Dravet syndrome. Across the board, the five-year open label extension data and phase I/II data that we anticipate having at the time of approval were the most compelling piece of evidence. When you think about payers, it is less important that it is included in the label and more important that the data are disclosed and peer reviewed. Payers are going to look at the totality of the evidence.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

They will look at published manuscripts, data presented at scientific congresses, the phase I/II and OLE data that we have generated to date, right? Four years of OLE data plus the phase I/II. I think it is not all anchored to the secondary endpoints. One of the things payers told us loud and clear is that the additional seizure reductions that you are seeing on top of the best standard of care medicine will drive significant value. With that being said, they will look at the totality of evidence. They will look at the data that are published in, for example, The New England Journal, right? That comes with a significant amount of credibility.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

We're feeling really confident in how we think about the value proposition and value story for zorevunersen, and that it really should command rare genetically targeted disease modifying pricing potential consistent with what we've been talking about over the last few months. Hopefully that answers your question a little bit, Pete.

[Pete Stavropoulos, Director of Biotech Equity Research at Cantor]

Thank you. Our next question comes from the line of Yaron Werber with TD Securities.

[Yaron Werber, Managing Director and Senior Biotechnology Analyst at TD Securities]

Great. Thanks so much and congrats on really terrific progress. Maybe I have a couple of questions. The first one is, given that you're going to have six-year data from the OLE which potentially can be label-enabling. How does that jive with the phase III data? Can they be synergistic? Do you need to hit all the same points in the phase III that you showed in the phase I/II? You noted to us, obviously, that the delta that you're looking for is a lot smaller, and you're obviously very overpowered. Secondly, I know you don't know exactly how you're going to rank order hierarchically yet in the SAP, the secondary endpoints. Maybe from you, based on your data, what is your wish list? Which endpoints are the most important? Thank you.

[Ian Smith, CEO at Stoke Therapeutics]

Yaron, thank you for the question. As I had mentioned in my earlier comments, we're heading to the FDA to discuss the pre-NDA and to have a pre-NDA discussion. One of those topics will be the six-year data or the five-year OLE data. You asked whether it's synergistic. Absolutely. Yes, it is synergistic. It is also additive. The importance of that data is that it demonstrates how the medicine is benefiting these patients as well as safety, but is benefiting these patients over a chronic period. This is a chronic disease, and our medicine is a chronically dosed medicine. The OLE data allows us to understand the benefits these patients are gathering with seizure reductions being durable through a five-year period, and also to see these cognition behavioral gains that they're having over a five-year period.

[Ian Smith, CEO at Stoke Therapeutics]

It is absolutely consistent and additive and synergistic to how we think about the phase III and will be supplementing the phase III data in our submission. That's why we continue to discuss it with the FDA. It's really important. As Jason says, the OLE data is also important in terms of how we, one, educate payers. They look at the totality of the data. I'll also say prescribing physicians, a really important piece upon approval of this medicine will be having physicians understand how to use the medicine, but what benefits it provides to patients beyond the one-year registration trial and those clinical endpoints. We're in great shape with that data. As you said, Yaron, we'll have six years of data by the time that we start our NDA submission of that clinical data package.

[Ian Smith, CEO at Stoke Therapeutics]

You asked about the importance of the secondaries and the hierarchy. At this point in time, we look at the hierarchy of endpoints. Number one, in terms of the primary, secondary endpoint is actually continued seizure reduction. Once you get beyond there, you get into the Vineland points. We've included communication, receptive and expressive communication as being the key measures in terms of the hierarchy. That's on the basis of physician and caregiver feedback. We're fortunate that that's where we're seeing benefit through our OLE data as well. Just to give you an idea, because when we talk about Vineland as a measurement tool of cognition and behavioral benefits, what that actually means is these children that unfortunately stagnate at the age of approximately 24 months, don't acquire other skills while they chronologically age.

[Ian Smith, CEO at Stoke Therapeutics]

We appear to be providing benefit where we're giving them function and giving them skill. In the communication area, for example, we appear to be helping these young children who can barely talk and have a minimal number of words they can use. We're providing the ability to many more words to actually use sentences. That's a progression they wouldn't otherwise see. We're also seeing them receiving communication, which allows them to respond, and respond to their parents as a real-world example. When you go on further and look at some of the motor skill acquisition, you're seeing children that improve their motor skills. That includes non-ambulatory becoming more ambulatory, frankly. This is data that's been collected from our OLE study, and it's been shared with videos that are in The New England Journal of Medicine. Have that validation and credibility.

[Ian Smith, CEO at Stoke Therapeutics]

That's what Vineland means. It is for us now to turn these Vineland scores into what real-world skill and task acquisition is for a Dravet child that otherwise would stagnate at the unfortunate age of 24 months. We want to provide them skill and acquisition based on the use of our medicine.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

I might just add, Yaron, this is Barry. Despite the wish list that we have, the powering of the study for the key secondary endpoint is for each of the individual Vineland subdomains. We power to the one that we think may even be the least likely to achieve. Each one of those have their own high degree of power.

Thank you. Our next question comes from the line of Laura Chico with Wedbush.

[Laura Chico, Managing Director and Co-head of Healthcare Research at Wedbush]

Good afternoon. Thanks very much for taking the questions. Maybe just one for Jason on commercial. You previously indicated most U.S. Dravet cases are managed at centers of excellence. How should we be thinking about site capacity to treat with an intrathecal ASO program? I guess I'm thinking a little bit more about logistical constraints like procedure slots and imaging. How do you think about site capacity and the impact on a commercial Dravet nursing launch? We obviously saw this was important for drugs like SPINRAZA. I'm just kind of trying to understand how things might have changed in the landscape. Thank you.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

Yeah, it's a great question, Laura. I think we provided some additional details here this afternoon around specifics for the top 50 sites, for example. If you think about those top 50 sites, all of them have 20 or more patients that are under their care. All 50 of those sites also have experience administering intrathecal therapies, most of them SPINRAZA. Given the efficiency that they've developed administering other intrathecal products and their familiarity with the procedures and process that goes into it, we feel like they are really set up incredibly well to handle the capacity that comes through at the time of a potential approval. Which we expect to be robust, if based on nothing else, based on the speed with which we recruited the EMPEROR study, but it's also consistent with what we hear in market research.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

We still have more work to do around site readiness and site qualification over the course of the next year or so. Going in, we're definitely benefiting from the fact that there are other intrathecally administered antisense oligonucleotides available in the commercial context, and that institutions have protocols already in place with how they're administering those therapies, which gives us a huge advantage going into a launch like this.

[Laura Chico, Managing Director and Co-head of Healthcare Research at Wedbush]

Thank you. Our next question comes from the line of Sumant Kulkarni with Canaccord Genuity.

[Sumant Kulkarni, Managing Director at Canaccord Genuity]

Good afternoon. Nice to see the progress and thanks for taking our questions. On slide 11 in your presentation accompanying this update, you mentioned that HCPs and payers indicate that OLE data may be the most compelling data at the time of approval. You alluded to this a little bit, and we understand reduction in seizure frequency over and on top of standard of care and totality of evidence matters. What specific components of the OLE data resonate most? Does the relative importance of the components of the OLE data vary for HCPs and payers, or are those factions looking at them largely in the same way?

[Ian Smith, CEO at Stoke Therapeutics]

Sumant, thanks for that question. Obviously, Jason's going to take this question. I just want to reiterate what Jason's about to tell you about the importance of that data is, yes, it's our belief, but this is feedback from prescribers and payers. It's what they're telling us. It's not what we are telling you. It's actually what the payers and the prescribers are telling us because we've gone out, and as you appropriately should be doing at this stage, but drug development is you should be doing diligence with your payers and your prescribers and helping them understand the medicine. But Jason.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

Yeah. It's a great question, Sumant. Thank you for it. I'll take those two audiences in sequential order there. Starting with the healthcare providers. I think it goes back to when you ask healthcare providers and caregivers specifically, what are the greatest unmet needs that exist in Dravet today? First and foremost, the number one that you hear is persistent seizure burden. The fact that very few patients ever reach seizure freedom is number one. I think that from a caregiver perspective, relates back to watching your child undergo a seizure, for example, right? Not far behind the persistent seizure burden is the lack of efficacy across the non-seizure manifestations of the syndrome and the lack of any targeted medicines that address the underlying genetic cause.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

When we talk to healthcare providers and they talk about what's most compelling to them, obviously the long-term data are the most compelling because as a clinician, they're sitting across from a patient where they're thinking about prescribing a chronic lifelong treatment. They want to understand what the implications are of administering this medicine to these patients over a long period of time. I think they're reassured by the long-term safety profile now going out four years of OLE plus the phase I/II. They're reassured by the persistent reductions in seizures that they're seeing, the durability of that seizure response. They're certainly reassured by the fact that you see the consistent gains in adaptive behavior and the neurocognitive endpoint as measured by the Vineland Adaptive Behavior Scale. In addition to that, it's quality of life measures, right?

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

As you think about what matters to families, the ability for a child to be able to communicate with their family, the ability to, for example, feed themselves. All of those little activities of daily living and acquired skills, as Ian mentioned, really matter a lot. When you think from a payer perspective, payers care less about, for example, the nomenclature associated with disease modification. What they care about more is, "Is this new treatment offering something that what I currently have at my disposal for my members isn't?" It's what we're doing in the non-seizure manifestations of Dravet syndrome above and beyond the seizure suppression. They're seeing the additional seizure suppression on top of the best standard of care as being a real value driver.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

Above and beyond that, the fact that we're affecting other elements or other manifestations of the syndrome really go a long way with payers in driving that value proposition associated with zorevunersen.

[Sumant Kulkarni, Managing Director at Canaccord Genuity]

Thank you.

Thank you. Our next question comes from the line of Kevin Strang with Goldman Sachs.

[Kevin Strang, VP and Biotechnology Equity Research Analyst at Goldman Sachs]

Good afternoon. Thanks for taking the question. Just a quick one on, you mentioned a study for infants and toddlers under 24 months of age, as well as generating new data in adults. I just wanted to ask about those two bookends. Anything on trial design, potential timelines for both of those? Then for adults specifically, is there any data that you can leverage from your OLE in terms of patients that have crossed over to adulthood? Thanks.

[Ian Smith, CEO at Stoke Therapeutics]

Yeah. Thanks, Kevin, and appreciate the recent initiation and also the data you sent to us this week about some analysis you've done of the market. First of all, the infant toddler study is part of the requirement for a PIP in Europe. We're running that study there. It really is as straightforward as that. Although, the data will help us potentially expand the label and treat even younger patients. Obviously with a genetic medicine, the earlier you can treat a patient, the more potential you have to put them back on a more neurotypical pathway, as well as prevent those seizures. It is a very important study, to get to these Dravet children as early as possible. For the adults, it's a different rationale. The adults, we anticipate that on successful data and approval that our label would be for two years and older.

[Ian Smith, CEO at Stoke Therapeutics]

Therefore we will have access to be able to have prescriptions to adults. What the adult study will do, though, it'll help us understand the benefit for adults and help provide access and reimbursement for those adult patients. You are correct. Our studies have been run so far for ages two through 18 years of age. The OLE does have patients that have progressed, that started in their late teens and have progressed into their early twenties now. We continue to track that data, and that data continues to show a durable seizure reduction and cognition and benefit from the first start of dosing when measured to their baseline when they were in their teens.

[Ian Smith, CEO at Stoke Therapeutics]

Our own principle on this is given that the root cause of Dravet is the lack of normal expression of NaV1.1, whereas we upregulate NaV1.1 protein, and therefore there should be no difference in providing benefit to, let's say, a 15-year-old versus a 21-year-old. We'll use all that data. We will also run an adult study that begins later this year. You also asked as far as the design of those studies. They'll initiate later this year, and as they initiate, we'll provide you study design at that time.

[Kevin Strang, VP and Biotechnology Equity Research Analyst at Goldman Sachs]

Great. Thank you.

[Operator]

Thank you. Your next question comes from the line of Joseph Stringer with Needham & Company.

[Joseph Stringer, Managing Director at Needham & Company]

Hi, thanks for taking our question. Just a follow-up on the market opportunity in Dravet syndrome. You estimate the prevalence in the U.S. is around 16,000. What do you estimate the current diagnosis rate is in the U.S.? If there is a disease-modifying therapy available, such as zorevunersen, and how significantly do you think the diagnosis rates could improve in the U.S.? Maybe as a follow-up question, I guess, what are the most appropriate drug comps that we should think about that have a similar setup to what there is for Dravet syndrome now, just multiple approved drugs on the market for several years, but no disease-modifying therapy available. Thank you.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

Thanks for that, Joseph. Maybe taking the first part of your question of the 16,000. When we look at claims data, we have a pretty good idea where about up to 80% of the 25 and younger patients are being cared for today. I would say that the genetic testing status in the U.S. has really grown dramatically over the course of the last five to 10 years. I would say that pediatric epileptologists, pediatric neurologists are doing a really nice job at diagnosing pediatric patients even earlier. There is a gap that still remains for the older patients. The disproportionate, I would say, majority of the diagnosed patients today are the diagnosed patients that are 25 and younger, of whom we expect there are about 6,000 that will be immediately addressable at the time of a potential approval.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

That's based on both Epi and what we're seeing in claims data. If you look at total unique claims across all ages, you get pretty close to that 6,000 number in the U.S. When you break it down and you apply machine learning where you're looking at that peri-diagnostic period, looking at concomitant meds, concomitant procedures, CPT codes that are commonly used for Dravet patients and apply that to the total claims universe, that's how we get to knowing where approximately 80% of the patients are being cared for. Not surprisingly, one of our focal points right now is enhancing and increasing genetic confirmation of diagnoses in that young adult into adult cohort of patients. With that being said, we feel like the DMT introduction with the potential approval of zorevunersen will dramatically increase the volume of genetic testing in the U.S.

[Jason Hoitt, Chief Patient Officer at Stoke Therapeutics]

We've actually asked that question of healthcare providers, and healthcare providers themselves anticipate that genetic testing will increase 85%-90% compared to today with the introduction of a disease-modifying treatment. The foundation is there. Our hope is to be able to drive those earlier diagnoses and, in the case of the adult patients, intervention before approval with additional diagnoses and genetic testing. From a comps perspective, Joseph, from a comps perspective with, I think SPINRAZA, the SMA market is a good comp. I think potentially the CF market is a good comp, where you had symptomatic treatments available before the introduction of the first disease modifiers.

Our next question comes from the line of Jessica Fye with JPMorgan.

[Adam Schlagman, Equity Research Associate at JPMorgan]

Hello, this is Adam on for Jess. Thank you for taking our question. Really just want to talk about the SYNGAP program. Just curious on timelines here. When can we expect a candidate to maybe enter the clinic?

[Ian Smith, CEO at Stoke Therapeutics]

Adam, thank you for joining the call. I'll start with SYNGAP remains a very important disease area for us. Just why? Because there's a lot of closeness of SYNGAP to Dravet in terms of being a neurodevelopment disease. Our platform that upregulates the effective gene to create protein in these patients is applicable to Dravet, as we've talked about today, it also goes to SYNGAP. SYNGAP becomes a very important area that we are focused on. We currently have five potential drug candidates that we're studying pre-clinically. We're working through our animal models, and in 2027, we hope that we will pick a development candidate to move then towards the clinic. I want to reiterate that it's a really important disease area for us to continue our efforts.

[Ian Smith, CEO at Stoke Therapeutics]

We have success and using Dravet as a proof of principle that our platform can work in these kind of disease areas. We will continue our efforts there to do the best for the patients.

[Adam Schlagman, Equity Research Associate at JPMorgan]

Thank you. Our next question comes from the line of Delma Caiati with Guggenheim.

[Delma Caiati, VP of Biotech Equity Research at Guggenheim]

Hi, good afternoon, thank you for taking our question. On the ADOA program, the Sentinel cohort dosing is now complete. Can you give us any color on how many patients were dosed and at what dose level? What did the Sentinel safety review show that supported the decision to escalate? For the readout in the first half of 2027, what magnitude of change would you consider as proof of concept threshold? Thank you.

[Ian Smith, CEO at Stoke Therapeutics]

Delma, thanks for the question. I'm going to have Barry summarize the program more holistically, to help you understand the decision we made to go into the clinic, which was based on pre-clinical data, obviously. Where we are in advancing a dose-escalating study where we're already into the increased doses. Barry, please.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

Yeah, thanks. Thanks for the question, Delma. Just as a reminder, ADOA is due to a haploinsufficiency or half a normal amount of OPA1 protein, which is required for mitochondrial function. We do have pre-clinical data in an NHP that has a genetic mutation that's similar to what patients have and has a similar phenotype to patients. There, when we administered STK-002 to those animals, they showed an improvement in their mitochondrial function, as well as an improvement in the function of the optic nerve. That gave us a high degree of confidence moving forward into the clinic, as well as other data that has come in the field. The study is a typical dose escalation study, a single ascending dose study, and the first cohort had three patients in it.

[Barry Ticho, Chief Medical Officer at Stoke Therapeutics]

The safety monitoring committee reviewed those data and are approving the escalation to the next dosing level. We have right now four dosing levels that are planned, and each of those are being reviewed for safety on a variety of levels after the injection. We'll also be looking for potential improvement in vision, because since we are improving the mitochondrial function in the patients, we expect that the retinal ganglion cells that are important for vision will be improving in their function as well. That will allow for better visual acuity, as well as improvement in the measure of mitochondrial function, which is what we call the FDF. Those data we anticipate being able to discuss next year.

[Ian Smith, CEO at Stoke Therapeutics]

Delma, I would just point out that as we progress through these four cohorts of increased dosing, we anticipate, based on our pre-clinical work, that we may start to see efficacy in cohort three or four, and that's why Barry is referring to data readouts that would be in first half of 2027.

[Delma Caiati, VP of Biotech Equity Research at Guggenheim]

Great. Thank you.

Thank you. Our next question and last question comes from the line of Rudy Li with Wolfe Research.

[Rudy Li, Director and Senior Research Analyst at Wolfe Research]

Hey, thanks for taking my question. As we finish enrollment of the phase III trial, can you maybe provide more color on the patient population, baseline characteristics as expected? Any notable difference versus the phase I/II trial? Thanks.

[Ian Smith, CEO at Stoke Therapeutics]

The patient population for the EMPEROR phase III study is consistent with the patients that came into the phase I/II and progressed into the OLE study. Just to ensure that we had an eight-week screen period that required certain baseline characteristics to be tested through that eight-week screen period before they were allowed into the phase III EMPEROR study. Characteristics, obviously age had to be screened, the SCN1A depletion gene and also a certain number of seizures. There is a similarity and a consistency between the phase I/II OLE patients and those that are in our phase III.

[Rudy Li, Director and Senior Research Analyst at Wolfe Research]

Cool. Thanks for confirming.
