Speaker 1

Please note that portions of the following discussion, including our responses to questions, contain statements that relate to future events and performance rather than historical facts and constitute forward looking statements. Our actual results might differ materially from those projected in these forward looking statements. Additional information concerning factors that could cause our actual results to differ materially from those in these forward looking statements is contained in our SEC filings, including our current report regarding our Q4 2023 financial results filed on Form 8 ks that was furnished to the SEC today. We undertake no obligation to update any forward looking statements after this call. And now I will turn the call over to Robert.

Speaker 2

Thank you, Diane, and thanks for joining us on the call today. The Q4 of 2023 represented a transformational inflection point for our company as we turn the card on SEQUAY HCM, our Phase 3 clinical trial of afacamten for the potential treatment of patients with hypertrophic cardiomyopathy or HCM. The results exceeded our already high expectations and we began 2024 firing on all cylinders with renewed commitments to preparing for regulatory interactions and submissions with urgency, executing on the broad clinical development program following behind Sequoia HCM as well as activating the next phase of commercial readiness activities. On today's call, Fady will discuss our plans for presentation and publication of primary and other results of Sequoia HCM, which will further elaborate on the efficacy and safety of our next in class cardiac myosin inhibitor. And as well, we're how we're moving swiftly to regulatory submissions across the globe and then Andrew will comment on how we're prudently planning for differentiated commercial positioning for our next in class opportunity.

Speaker 2

As important as Sequoia HCM is to our path to commercialization, there's much more in our pipeline that we believe will meaningfully unlock shareholder value as the company continues to mature. Stuart will provide an update on the progress of Maple HCM and AKASA HCM, the additional Phase 3 clinical trials of afikamten, which will provide an on ramp to potentially expanding the utility of cardiac myosin inhibitors as a first line treatment for obstructive HCM as well as potentially provide a new treatment option for the growing number of patients with non obstructive HCM. As you'll hear, there's been an increased enthusiasm and activity surrounding these trials on the heels of the positive results from SEQUOIA HCM. However, much still remains ahead of us to bring afikamtine to patients, but I'm confident in our ability to execute on our ambitious strategies. As you'll hear in more detail, we ended 2023 with a strong balance sheet, thanks to reduced spending during the year.

Speaker 2

In the last quarter and earlier this year, we also added to our cash balance with an infusion of capital from our at the market or ATM equity vehicle. We're pleased to be reporting our financial guidance today with approximately 2 years of cash runway when accounting for both our cash on hand and cash available to us and despite projecting an increase in our expected operating expenses in 2024. Recently, we announced the retirement of Qing Zha from his position as CFO in order to attend to his personal health. Qing's departure is unrelated to our business prospects and on mutually good terms with the company. On behalf of our senior leadership team, we support his decision for his well-being and we express our gratitude for his many contributions to our company.

Speaker 2

Qing built a strong team that many of you may know, including Robert Wong, VP and Chief Accounting Officer as well as Matt Yang, VP of Corporate Finance and FP and A. Together with the teams they have assembled, we're confident that Ching's departure will have minimal impact to day to day financial operations. Libby Schneiders, our SVP of Business Development, who has served our company for well over 20 years continues to lead Business Development, so we do not foresee any impact on that front. Furthermore, in anticipation of Ching having to attend to his health in the Q4 of 2023, we brought on a seasoned consultant who previously served as CFO of a public biopharma company and who has extensive experience in financial planning and structured finance transactions. He'll continue to work with me through this transition as we've already initiated a national search for Ching's replacement that we expect will bring international commercial and capital allocation experience compatible with maturing operations.

Speaker 2

Cytokinetics is looking ahead to a bright future in 2024 and also beyond. And as we turn the page towards potential commercialization of the first medicine arising from our pioneering and leading muscle biology research with more to come as we continue to prosecute our R and D programs. We're fortunate to be where we are today, but it is not by coincidence. It's a result of meticulous planning, risk mitigation, strategic foresight, perseverance and dedication. We're building a specialty cardiology company, leading with apicamten as the foundation, and we have the pipeline, the passion and the people to make happen that vision as we believe will further reward shareholders.

Speaker 2

With that, I'll turn the call over to Fady, please.

Speaker 3

Thanks, Robert. During the quarter, we shared top line results from Sequoia HCM, which as Robert said, exceeded our expectations. It was a truly extraordinary milestone, reflective of an incredible commitment from so many, including our investigators, study staff, patients and of course our teams at Cytokinetics. The results of SEQUOI HCM showed that treatment with apicamten significantly improved exercise capacity compared to placebo, increasing peak oxygen uptake or peak VO2 measured by cardiopulmonary exercise testing by a least square mean difference of 1.74 milliliters per kilogram per minute with a p value of 0.0002. The treatment effect with apikamten was consistent across all pre specified subgroups, reflective of patient baseline characteristics and treatment strategies, including patients receiving or not receiving background beta blocker therapy.

Speaker 3

Statistically significant and clinically meaningful improvements with a P value of less than 0.0001 were observed across all 10 pre specified secondary endpoints, including the Kansas City cardiomyopathy questionnaire clinical summary score at weeks 1224, the proportion of patients with a greater than or equal to 1 class improvement in New York Heart Association functional class at weeks 1224, the change in provoked left ventricular outflow tract gradient and proportion of patients whose gradient fell below 30 millimeters of mercury at weeks 1224 as well as exercise workload and guideline eligibility for septal reduction therapy. These positive results reflect rapid and sustained improvements of symptoms, functional capacity and heart failure status. Apicamten was well tolerated with an adverse event profile comparable to placebo. Treatment emergent serious adverse events occurred in 8 patients or 5.6% on apikempton and 13 patients or 9.3% on placebo. Core echocardiographic left ventricular ejection fraction or LVEF was observed to be less than 50% in 5 patients or 3.5 percent on apikamstan compared to 1 patient or 0.7% on placebo.

Speaker 3

Importantly, there were no instances of worsening heart failure or treatment interruptions due to low LVEF. While these top line results provide a relatively comprehensive look at the overall effect of treatment with apacamten, we have an extensive plan to share the primary results and additional analyses in more detail in a series of published manuscripts and presentations. We hope the first of these to occur at Heart Failure 2024, the annual meeting of the Heart Failure Association of the European Society of Cardiology taking place in May in Lisbon. Along with the primary results from SEQUOIA HCM, over the coming months, we plan to present and publish key data that may lend support to the differentiated profile of apikamten. One important analysis is to examine the clinical effectiveness of apicamten in patients across several endpoints in aggregate, examining the breadth of improvements patients experienced in SEQUOI HCM.

Speaker 3

In another, we plan to elaborate on the dosing and safety experience from SEQUOI HCM, which we believe informs the potential safety and monitoring needed in the clinical environment. In addition to these important analyses from SEQUOI HCM, we have a robust scientific communications plan over the coming year that includes manuscripts and Congress presentations that will further elaborate on the effect of apicamten and other metrics of exercise capacity, cardiac remodeling from the CMR substudy, echocardiographic measures of systolic and diastolic function and cardiac structure, symptoms and quality of life and cardiac biomarkers. We look forward to sharing these analyses with you in 2024 starting in Q2. I'd like to acknowledge the tremendous efforts by our steering committee and internal teams to support and execute on this ambitious plan for publications and presentations. Shifting over to FOREST HCM, the open label extension clinical trial of afikamten, we can report that over 90% of the patients eligible from Redwood ACM and Sequoia HCM have enrolled in Forest HCM, representing nearly 300 patients that will contribute to our understanding of the effects of long term treatment with apicamten.

Speaker 3

Please note that this does not include patients from the China cohort of specific open label extension clinical trial. In April, at the American College of Cardiology Annual Scientific Sessions, we will present the efficacy and safety of apicamten in the first cohort of patients with symptomatic obstructive HCM that have completed 1 year of follow-up in forest HCM. Last month, we shared data at CMR 2024 from the cardiac magnetic resonance or CMR substudy of forest HCM. The results showed the treatment with apicamten for 48 weeks resulted in cardiac structural remodeling, improvements in cardiac function and stabilization of myocardial fibrosis, demonstrating that apicamten has potential disease modifying effects and ability to improve the architecture of the heart in patients with obstructive HCM. While this analysis is small, only 16 patients were eligible at the time of this data cut, we plan to expand on these data in the future as more patients reach the 1 year mark and beyond.

Speaker 3

Regarding regulatory engagements, during the month of February, we held 2 meetings with FDA ahead of our expected submission of an NDA in the Q3 of this year. A first meeting to review the results of SEQUOI HCM and a second pre NDA meeting providing an opportunity to align on the content and format of the NDA. We're pleased with the FDA's feedback supporting the sufficiency of our proposed NDA submission package and the receptivity to a rolling submission plan. We believe that the positive readout for SEQUOI HCM along with the favorable pharmacologic and DDI profile of apicamten continue to support the opportunity to achieve differentiated labeling and risk mitigation. We look forward to providing future updates regarding our interactions with FDA this year.

Speaker 3

As to regulatory planning and interactions in Europe, we're similarly ready for submission of our marketing application in the Q4 of this year and plan to meet with EMA in Q2 to inform preparations. Similarly, we're coordinating with our partner, Xixing in China to collaboratively support Xixing's plans to submit an NDA. Overall, our proactive planning in 2023 has enabled us to capitalize on the positive results from SEQUO HCM and to proceed with urgency towards global regulatory submissions as well as to consider expedited pathways consistent with our aggressive planning scenarios. Alongside all of this, from a medical affairs perspective, during the quarter, our therapeutic medical science liaisons continued profiling of HCM treatment programs, while our managed healthcare medical science liaisons began development of our payer clinical value proposition. We also continued our support of medical education activities at medical conferences.

Speaker 3

As Robert said, the strength of the specialty cardiology company we are building is anchored in the power of our research engine and development pipeline with apikamten, if approved, leading the way. The top line results from Sequoia HCM have been well received by the HCM community of physicians and patient advocates who foresee that they represent what can be a meaningful advance in care. We're grateful for their support and we look forward to continuing to engage with them as we work to establish apicamten as a potential next in class treatment option for patients with HCM. I'll hand it over to Stuart to elaborate more on additional clinical trials progress we're making with apicamten and provide an update on our earlier stage clinical development pipeline. Thank you, Patti.

Speaker 3

In addition to sharing positive results from SEQUOIA ACM, during the 4th quarter, we continued enrollment and are building momentum with our 2 ongoing Phase 3 clinical trials of africantha, maple HCM and Acacia HCM. We're pleased to see that screening and enrollment is accelerating and have been catalyzed by the announcement of results from Sequoia HCM. In Maple HCM, which is evaluating the potential superiority of epacamten as monotherapy compared to mentoprolol as monotherapy in patients with obstructive HCM, nearly all U. S. Sites are now activated and we've now activated sites in the U.

Speaker 3

K, France, Italy, the Netherlands and Israel. We expect to complete enrollment in Maple HCM in the Q3 of this year, which would enable results from Maple HCM to be available in 2025 concurrent with when we hope to be commercially launching afucanthan. We believe that if Maple HCM were to read out positively, it would provide support for the positioning of apacamten as a first line therapy for patients with obstructive HCM. We're developing apicamten to capitalize on its next in class potential and Maple HCM factors importantly into that strategy. ACATIA HCM, the pivotal Phase 3 clinical trial of apicamten in patients with symptomatic non obstructive HCM is currently focused on study startup.

Speaker 3

But we have the necessary IRB approvals in the U. S. And the EU progressing our clinical trial application through the new Harmonize procedure. We plan to hold investigator meetings for North America, South America and Europe in the Q2 and look forward to continuing enrollment in this trial through 2024 with the objective to complete enrollment in 2025. ACATIA HCM represents an important opportunity for abacamten and tests a key therapeutic hypothesis for expanding the evidence to support cardiac myosin inhibition in a growing population of patients underserved by current treatment options.

Speaker 3

We believe that the results from Sequoia HCM and Redwood HCM basically add confidence to what we can expect from Acacia HCM and our optimism is shared by clinical investigators. Both clinical trials have the potential to expand the utilization of apikamten in the HCM patient population and impact treatment guidelines. At the same time, we're pleased with the progress of our clinical trials of apicamten. In the past quarter, we also advanced our earlier stage development pipeline, notably with CK-five eighty six, our cardiac myosin inhibitor and development for the potential treatment of subgroup of patients with heart failure preserved ejection fraction or hep PEP. Having completed analyses of the single ascending dose data, we proceeded to the multiple ascending dose portion of the study.

Speaker 3

We expect to complete the Phase 1 study in this quarter and subsequently share data in the Q2 of this year with plans to begin a Phase 2 clinical trial in the second half of the year. We believe that the positive Phase 2 data we generated for apicamten in patients with non obstructive ACM support the development of CK-five eighty six in a population of patients with PEPPEP whose condition has many parallels to non obstructive HCM. Currently in the United States, there are about 3,600,000 people with hep hep, which is expected to increase to 4,800,000 by 2,033. Approximately 30% to 40% of these patients present with characteristics that may make their condition amenable to cardiac myosin inhibition. Even with SGLT2 inhibitors, the first evidence based therapies demonstrating some benefit in those who have PEF, there is still a high residual risk of cardiovascular events and a clear need for additional effective therapies.

Speaker 3

Additionally, during the past quarter for CK-one hundred and thirty six, our cardiac troponin activator, we continued analyses of the single and multiple ascending dose cohorts in the Phase 1 study of healthy participants and expect to complete the study in the Q2 of this year. In 2024, we plan to share more updates from our early stage pipeline and our research. As more programs mature from our labs into the clinic, we will report on how in recent years we've extended our focus in muscle biology beyond muscle contractility to also include other programs entering development representing potential innovations in muscle metabolism and energetics. While apicamten represents the most important near term value driver for our company, our early stage pipeline and emerging programs from ongoing research demonstrate productivity against our vision 2025. The long term goal is to cement our leadership in muscle biology adjacent to exciting developments and treatments for cardiometabolic syndromes.

Speaker 3

We look forward to sharing more progress soon. With that, I'll turn the call over to Andrew.

Speaker 4

Thanks, Stuart. During the quarter, ahead of our announcing results from Sequoia HCM, we continued commercial readiness activities for afacamten. Throughout 2023, our focus was on learning, the first phase in our go to market approach. We commissioned multiple market research studies seeking insights from nearly 850 healthcare professionals and more than 160 patients with obstructive HCM, which revealed that the HCM patient journey can be complex and challenging. Furthermore, HCM can also negatively impact patients' overall mental health, social engagement and other aspects of everyday life.

Speaker 4

We also tested a range of product profiles in market research prior to our receipt of the results from Sequoia HCM. The tested attributes most closely resembling the actual Sequoia HCM results revealed that healthcare professionals would perceive the results from Sequoia HCM favorably and would drive use of apacamten if approved across a broad range of obstructive HCM patients. These learnings are informing the strategic decisions we're making around the target product profile, positioning, potential customer profiles and our patient services hub. Access in particular is a key focus for us, Aligned with our company values of keeping patients at the forefront of all we do, we're designing a comprehensive patient support program to facilitate and support patients in transitioning to treatment with afacantin, inclusive of patient education resources and reimbursement support and affordability grant programs for eligible patients. In the Q4 of 2023, we held initial conversations with specialty pharmacies and patient service hub providers to support our build of a differentiated patient services hub.

Speaker 4

Now that we have results from Sequoia ATM this year, we are advancing to the 2nd and third stage phases of our go to market strategy, design and build. This year, we plan to build our patient support services, access strategy inclusive of distribution model, contracting approach and pricing. Our seasoned account manager team is fully staffed and interacted with every major payer in 2023 to introduce Cytokinetics. This field based payer account team will continue to further engage in 2024 to share the results from Sequoia HCM and ensure payers understand the clinical meaningfulness of the results. In 2024, we also plan to finalize our product positioning and launch our market development and education campaign, while we develop our branded marketing campaign in support of a potential 2025 promotional launch.

Speaker 4

As we previously shared, we began building our commercial capabilities in the United States prior to the potential FDA approval and launch of omecamtiv mecarbil. After receiving the CRL from the FDA, we maintained the infrastructure that had been built and further refined the team and activities to prepare for what now will be our 1st commercial launch with afacamten. Today, we have on board the majority of U. S.-based headquarter personnel that we expect to need, including marketing, field sales leadership and individuals leading insight generation, market analysis, commercial strategy, systems and operations. We expect to expand the team in 2025 with HCP customer facing positions gated appropriately alongside the regulatory process for apacamten.

Speaker 4

In Europe, having hired key leadership positions last year, including our Head of Europe and Head of Market Access, we plan to only modestly expand our EU staff in 2024, while maintaining disciplined eye to spending and gaining cost to regulatory submissions and feedback from Health technology assessments or HDAs. It is encouraging to see favorable benefit assessment from HDAs in both Germany and France related to cardiac myosin inhibitors as a new treatment option for patients with obstructive HCM and we believe this bodes well for future reimbursement of acacamten if approved across major European markets. Overall, I'm very pleased with the foundational commercial readiness work that we've completed ahead of sharing our results at Sequoia HCM last year, which sets us up to nimbly advance into the next phase of our planning in 2024 and can enable us to capitalize on what we believe will be differentiated positioning for aducamten in the treatment of patients with obstructive HCM. And with that, I'll turn the call over to Robert Wong.

Speaker 5

Thanks, Andrew. We ended the Q4 with $655,400,000 in cash and investments, which included $162,900,000 that we raised through our at the market equity vehicle in the quarter. Following the quarter close, we raised approximately 83,000,000 dollars net through yesterday with our ATM equity vehicle, which is not reflected in our year end balance. Our Q4 2023 R and D expenses increased to $85,000,000 from $75,000,000 in the Q4 of 2022, primarily due to spending on our cardiac myosin inhibitor programs. Our Q4 2023 G and A expenses were $44,100,000 down from $54,000,000 in Q4 2022 due primarily to lower outside spending on commercial activities offset by higher personnel related costs including stock based compensation.

Speaker 5

Overall, our net cash burn in 2023 was 4 $14,000,000 relative to what was our initial 2023 guidance of $420,000,000 to 450,000,000 dollars We believe we proved to be good stewards of shareholder capital by reducing spending ahead of the results of Sequoia HCM at the end of the year, which puts us in a stronger financial position to begin 2024. Now I'll hand it over to Robert Blum to review our financial outlook, 2024 guidance and corporate development strategies.

Speaker 2

Thank you, Robert. Today, we announced our financial guidance for 2024. The company anticipates revenue will be in the range of $3,000,000 to $5,000,000 operating expenses will be in the range of $420,000,000 to 450,000,000 and net cash utilization will be approximately $390,000,000 to $420,000,000 In terms of capital allocation, our priorities are focused on benefiting patients and enriching shareholder value, anchored by a prudent spending plan that balances advancing our commercial strategy with investment in our pipeline. Our foremost priority is advancing regulatory submissions for afikamten in obstructive ACM and ensuring commercial preparedness in key markets like the U. S.

Speaker 2

And Europe. Secondly, in continuing maple HCM and Acacia HCM, we plan to maximize the therapeutic potential of apicamten. And finally, we remain focused on growing our pipeline inclusive of CK-five eighty six and bolstering our R and D platforms to sustain future innovation. Inclusive of the approximately $83,000,000 net raised in recent weeks through our ATM as well as cash available to us under our loan agreement with Royalty Pharma, our current cash balance of $655,000,000 at the end of last year represents approximately 2 years of forward cash runway based on our financial guidance and projected 2024 operating expenses and net cash utilization. With positive results from Sequoia HCM in hand, we've been looking at the arc of capital requirements leading up to potential approvals and the global commercial launch of afikamten, as well as sustaining and growing R and D through profitability.

Speaker 2

As such, we continue to focus on a multi pronged approach to accessing capital that enables us to pull several different levers over time. As has been our history, we plan to monetize our R and D progress and preserve shareholder value via partnering as well as structural finance engineering and other non dilutive approaches. Our priority remains focused on business development. And as you know, we've been focused on a Japan deal for afecamten. We're in active discussions with multiple parties and I'm pleased with how that deal campaign is looking.

Speaker 2

Moreover, we're considering partnering CK-five eighty six for the potential treatment of HFpEF, while also preserving key rights for Cytokinetics in both co development and co commercialization. We believe that our long standing leadership in the area of cardiac myosin modulation for the treatment of severe cardiovascular diseases has enabled us to look at partnering in an advantaged way as would benefit shareholders while also preserving important shareholder value in major markets of value for AffyCampton. And additionally, we may consider restructuring our debt and other novel ways to build on the momentum from Sequoia HCM in structured finance transactions that we believe would augment shareholder value and importantly would not subtract from it. I'll remind you that through our transaction with Royalty Pharma, we remain eligible for 2 additional loan tranches under our development funding agreement. The first tranche of $75,000,000 became available upon our sharing positive results from Sequoia HCM and we remain eligible to draw down for 1 year following our receipt of the results, which occurred in late December.

Speaker 2

The second tranche of $100,000,000 will become available to us were we to choose to draw on it subject to the satisfaction of certain conditions, most notable of which is the acceptance of an NDA submission for apicamten in the United States. As we are now a company valued between $8,000,000,000 $10,000,000,000 we have an ambitious yet practical and realistic plan to increase shareholder value over the next 3 to 5 years to that which would be upwards of $15,000,000,000 to $20,000,000,000 How do we get there? By unlocking the value in our pipeline and maximizing our opportunities. It starts with apicamten in North America and Europe based on the results from SEQUOIA HCM. From there, we hope to increase value as maple HCM and ACASA HCM readout results that now have higher probability of technical success.

Speaker 2

And next then, we expect CK-five eighty six to advance through proof of concept and HFpEF with additional upside coming from our earlier stage pipeline. I also want to take a moment to address recent M and A speculation relating to Cytokinetics. Since sharing the positive results from Sequoia HCM, SatoKinetics has been rumored to be an acquisition target. While we will not and cannot comment on specific speculations, let me please be clear about one thing. We did not initiate nor do we have a sale process ongoing.

Speaker 2

However, as responsible fiduciaries to our shareholders, I can assure you that we thoroughly evaluate options that are presented and as you heard me say a moment ago, we continue to advance business development discussions. We're optimistic about how those discussions are proceeding and we're committed to building a sustainable specialty cardiology company as starts with executing against our goal of bringing new medicines to patients. We take great care in fulfilling our duty to shareholders by ensuring that we're doing the right thing to deliver maximal value and controlling that which we can control. We believe that can be best achieved by advancing our innovative science, ensuring operational efficiencies, and thoughtfully and prudently managing and deploying capital to maximize shareholder value. We're beginning 2024 in an advantaged position.

Speaker 2

We have turned the page to the next chapter of the Cytokinetics story and the work we're now undertaking will set the stage for our first potential regulatory approvals, we hope within the next 18 months. In the second half of this year, we expect to submit regulatory filings in both the United States and Europe for apicamten. You heard from Fady in Q3 an NDA with FDA and in Q4 an MAA with EMA. We expect to be more precise as timing goes to our Q1 earnings call and especially as it relates on positioning and other aspects contained within the content of those submissions. And we have ambitious goals beyond obstructive HCM as well as beyond apicamten, including expanding our development pipeline with new compounds arising from our research, extending beyond the contractility of muscle to the energetics growth and metabolism of muscle.

Speaker 2

Each of our programs in muscle biology has been designed to potentially address severely ill and underserved populations in need of new therapies and our vision of building a specialty cardiology company is now being realized and we're well positioned for success. With that, I'd now like to share our expected 2024 milestones. For apicamten, we expect to present primary results from SEQUOI HCM at a medical conference in Q2 2024. We expect to submit an NDA to the FDA in Q3 2024 and an MAA to the EMA in Q4 2024. We expect to complete enrollment in Maple HCM in Q3 2024.

Speaker 2

We expect to complete enrollment of Acacia HCM in 2025, but continue its enrollment in 2024. And we expect to continue advancing go to market strategies for afikamten. For omecamten mecarbil, we expect the CHMP to issue an opinion regarding the MAA in Q2 2024. For CK-five eighty six, we expect to share data from the Phase 1 study in Q2, 2024. And finally, for CK-one hundred and thirty six, we expect to complete the Phase 1 study in the Q2 of this year.

Speaker 2

And operator, with that, we can now open up the call please to questions.

Operator

Thank And our first question comes from Mayank Mamtani with B. Riley Securities. Your line is open.

Speaker 6

Good afternoon team. Thanks for taking our questions and hope for Ching's well-being too. So just quickly on the pre NDA meeting that occurred, I was just curious how much of the FOREST SCM data would be part of that submission? I believe by the ESC Heart Failure Congress, you'd probably have about 150 patients go through the titration phase. So just curious if how much of that is going to be important as part of the pre NDA meeting and eventually make it into the NDA submission?

Speaker 2

So I'll turn that call that question rather over to Fady.

Speaker 3

Thanks. So I can't give you the exact

Speaker 2

number of patients that will

Speaker 3

be available, but we also, besides the forest, the time of NDA submission, in forest, the time of NDA submission will also have the opportunity to submit an update at the day 120 time point, there's a day 120 safety update, where we can expand the data set. So we fully expect the number of patients with up to a year of follow-up to be perfectly adequate for their review.

Speaker 6

Understood. And a related question, just quickly, the Acacia at Centimeters, I'm glad you narrowed the timelines there. I was just curious, based on everything we know on dosing, safety, cardiac remodeling data, just your confidence level for that, what you could report there, also recognizing that a threshold could be set from the ODIC HCM study next early part of next year? Thanks again for taking our questions.

Speaker 3

Well, I think based on the results that we saw on Phase 2 and the predictability of dosing and the safety profile we saw of apicamten and SEQUOIA, we feel very confident with the outcomes in potential outcomes in Acacia. So I think all of them read well on the likelihood of that trial reading out positively and we'll continue to conduct it in a way that helps us get to the best answer.

Speaker 2

Thank you for the question. Just a reminder please, one question per analyst, please. Next question, please.

Operator

Our next question comes from the line of Salim Syed with Mizuho. Your line is open.

Speaker 2

Good afternoon, Salim Syed.

Speaker 7

Hey, good afternoon, Robert, and hello, everybody. Robert, I just wanted to focus on maybe that's for Fadi as well, but on the rolling submission, what exactly is going in first?

Speaker 3

I believe it's the first time

Speaker 7

you guys are using that terminology, if I'm not mistaken, rolling submission for afacamten. So what exactly is going in first? And then what is the piece that you plan to submit later? And then curious also if the rolling submission, if that in any way encompasses the potential to submit the Maple HCM data, because you're going to get that before an approval decision? Thank you.

Speaker 2

Yes. So I'll answer that question. So you're right, we are using that terminology for the first time and that's coming out of our recent meetings with FDA. We're very encouraged by what appears to be a leaning forward and willingness to consider these data sooner. We're looking at how we might accelerate submission.

Speaker 2

And in that regard, they were amenable to our recommendation that we do it in a rolling basis. We're going to be submitting most of the modules earlier than what's going to be the long pole in the tent, so to speak, in terms of what will be coming in later will be some of the CMC data that we're still in the process of finalizing, in light of the fact that there are certain time points we need to collect in order to be able to finalize those submissions. But all this speaks to, we think, a focus forward in connection with a submission that could be started sooner. Keep in mind that the actual filing doesn't change. That ultimately depends on the final modules as they are then submitted, but it certainly allows the review to begin.

Speaker 2

As it relates to Maple, no, we don't expect that those data will be contained in this submission. Maple won't read out till next year.

Speaker 7

Okay, got it. Thank you very much.

Our next question comes from the line of Ashwani Verma with UBS. Your line is open.

Speaker 8

Hi, there. It's Fatima on behalf Hi, good afternoon. Fatima on behalf of Ashwani Verma from UBS. Just a general quick question. In terms of cardiology in general, just a high level, is portfolio level

Speaker 2

I don't understand that question. Might you repeat it, please?

Speaker 8

Sure. Yes. I'm just trying to understand like in the cardiology space, is portfolio level contracting common? Like do you think companies that have like a broad set of diverse portfolio in cardiology, they have like a larger benefit compared to companies that are focused on single assets.

Speaker 2

I see. Your question is, are we going to be potentially disadvantaged because we'll be launching with a single product relative to payers, I assume, who might have multiple who might be contracting around multiple products. Is that right?

Speaker 8

Yes.

Speaker 2

So from a payer

Speaker 4

point of view, no, I don't believe we're at a disadvantage. Payers aren't managing this category. It's a rare disease. There's over 120 payers in the U. S.

Speaker 4

Each payer only has very limited number of patients. It's not a big budget impact. It's a high unmet need. There's one product in the market, a second product. So these usually aren't payer managed categories.

Speaker 4

From a cardiology point of view, The focus of a subset of cardiologists was what we will focus on those that diagnose and treat HCM as a subset of overall cardiology and highly motivated to treat the disease. So they're going to be more focused on the products, the patients relative to the disease. So by all means, I think we'll compete fine and it's not going to be at a disadvantage.

Speaker 8

Okay, great. Thank you so much for taking our question.

Speaker 2

Thank you.

Our next question comes from the line of Maya Iskanderani with Barclays. Your line is open.

Speaker 2

Good afternoon.

Speaker 9

Hi, this is Carter. Thanks for taking the question, Robert. Maybe for Robert and Fady, the commentary on the REMS sort of reference SEQUOIA PK and the DDI profile, all of which we've known for a while, I guess now, but can you comment if the FDA interactions in any way shifted or reaffirmed your belief in that differentiated label for REMS? Thank you.

Speaker 2

Yes. I'll just comment very briefly. It's premature because those conversations will continue, but reaffirming our view that between positioning, labeling, lesser REMS and other things that read on safety and risk mitigation that we'll be in a position to have a very constructive fruitful conversation with FDA. Next question, please.

Operator

Our next question comes from the line of Paul Choi with Goldman Sachs. Your line is open.

Speaker 2

Good morning. Good afternoon, Paul.

Speaker 10

Hi, Robert. Good afternoon, team. My question is, with regard to your recent meeting with the FDA, can you maybe just confirm for us if there were any either preclinical or clinical testing requirements that were specified by the agency? And to the degree there are any, how much of this needs to be coordinated with EMA requirements ahead of a potential MAA file in addition to NDA? Thank you for taking our question.

Speaker 2

Sure. We don't believe there are any other such studies that are required. Okay, great. Hopefully that addresses your question well. Thank you.

Operator

Our next question comes from the line of Tess Romero with JPMorgan. Your line is open.

Speaker 11

Hello, good afternoon. I'm Adi on for Tess. So we just wanted to ask, is there any data from Sequoia that you are yet to see at this point?

Speaker 2

I'll turn that over to Fadi.

Speaker 3

We've seen the full set of data. I wouldn't say every analysis you could imagine has been complete that may go on for years to be honest as we think of new analyses. But all the pre specified analyses for example, the clinical study report have been completed and reviewed in detail.

Speaker 2

Got it. Thank you. You'll also see this laid out in full glory in the second quarter. We expect multiple presentations, multiple publications. Next question, please.

Operator

Our next question comes from the line of Yasmeen Rahimi with Piper Sandler. Your line is open.

Speaker 8

Good afternoon, team, and thank you for all the thoughtful remarks. I guess, it's been now 2 months since the top line data. Have you had a chance to complete all your REMS preparation by hiring the data on the integrated basis, coming up with a package and kind of laying out sort of the proposal. Like could you maybe give us a color on which of these activities have been completed? What is left to do?

Speaker 8

How much of the proposal, I guess, is in its finishing process? And thank you again for allowing me to ask my question.

Speaker 2

Thank you, Yasmeen. I'll take that one then. We are in the process of doing just what you are asking. I don't think that's the kind of thing that we're going to choose to elaborate on publicly. That's obviously something that informs competitive positioning.

Speaker 2

I do believe to elaborate on Carter's question that we're going to be potentially able to consider how we may be differentiated and advantaged in ways that could be enabling avafacamten to be accessed by a greater number of physicians for a greater number of patients. And as it relates to how that REMS may be positioned situated, what would be the elements of it, that's something that I think will be the subject of negotiation at the end of the day during the review period of an NDA after it's on file. So that's not something I expect we'll be providing play by play visibility to until such time as we believe that there's certainty around what that looks like.

Speaker 8

Got it. Thank you so much, Robert, and keep up the amazing work. I'll be back in the queue.

Speaker 2

Thank you so much.

Operator

Our next question comes from the line of Jason Butler with JMP Securities. Your line is

Speaker 2

open. Hi,

Speaker 4

Robin team. This is Jose for Jason. Thanks You mentioned that the data from Forest HCM demonstrate favorable structural remodeling. Could you speak to the potential long term functional benefits of such remodeling in HCM patients? And as a quick follow-up on apicamten, do your discussions with payers give any insights into the potential risk pricing versus the standard of care?

Speaker 4

Thank you.

Speaker 2

So I'll ask Fady or Stuart to address the first question.

Speaker 3

Yes, Dana, this is really a really key question that we are anxious to investigate, certainly in the long term because what we hypothesize is that cardiac myosin inhibition will result in a long term very favorable remodeling and hopefully normalization of cardiac structure and function and we anticipate that that will mediate, confer lifelong benefit for patients in terms of symptomatic and functional improvement. And we could also hypothesize reduce risk of cardiovascular events. I might just add that the data we reported in January are really just the first taste of the CMR cohort, which I think is the largest cohort of patients that will undergo serial CMRs at 1 yearly or every other yearly intervals. And so the number the length of time those data will mature as the years go on and I think give us a very good sense of how the cardiac structure changes over time.

Speaker 4

From a pricing point of view, we will be sharing Sequoia HCM results with payers once the Sequoia HCM results are published. There is one product on the market today, obviously, that has a list price will be in the range of that list price, whether we're at slightly above, slightly below, we haven't finalized where we'll be in pricing, but we'll finalize that as we get closer to launch next year.

Speaker 2

And those are not the kinds of things that one talks about at this point in time. Thanks. Thanks so much. Next question please.

Operator

Our next question comes from the line of Joe Pantginis with H. C. Wainwright. Your line is open.

Speaker 3

Hey, Joe. Hey, everybody. Good afternoon. Thanks for taking the question. So I think my question is more suited for or most suited for Andrew.

Speaker 3

I know you guys from an internal standpoint don't want to talk about the competitive profile or what you're thinking, but curious from your marketing research and talking to physicians and polling, etcetera, the profile data from SEQUOIA, has it led to any data that you can discuss regarding physicians' willingness to switch from KAMZYOS early on or needing more real world data in order to get educated about the drug apacamten?

Speaker 4

We haven't focused on that. We're completely focused on making sure that patients who are on beta blockers, calcium channel blockers, not on standard of care, not on disease modifying therapy are activated towards the CMI, educate those physicians on hopefully the label and REMS program associated with apicamten as soon to be approved. And we're going to focus on activating and getting patients on therapy. We're not going to focus on patients who are already on an existing therapy. That's really up to a physician patient dialogue if they choose to go that route.

Speaker 3

Very clear. Understood

Speaker 2

for a next in class opportunity like we believe affecamten represents, it's incumbent upon us to think about how might this lead to an expansion of the category for the benefit of more patients at the end of the day and that's where our focus is.

Speaker 4

And we do think that there's over well over 100,000 patients who will be eligible. Our best guess is that the vast majority of those will still be available for a CMI treatment when we come to market.

Speaker 3

Fantastic. Thank you.

Operator

Our next question comes from the line of Jeffrey Huang with Morgan Stanley. Your line is open.

Speaker 12

Hi, good afternoon. Hi, good afternoon. This is Catherine on for Jeff. Thank you so much for taking our question. We just had a quick one.

Speaker 12

I'm just curious from your conversations or interactions with providers, have they expressed any enthusiasm about the potential for a less restrictive REMS program or have they indicated whether they feel the data might be supportive of that?

Speaker 3

Well, we certainly, spoken to providers and they're optimistic given the safety profile that we shared with them in the SEQUOIA data. But they really obviously don't contribute to the FDA's evaluation of that question. And we'll be proposing something based on the findings that we have and the accumulated data that we have. So I would just stay tuned.

Speaker 12

Understood. Thank you so much.

Speaker 2

Thank you.

Operator

Our next question comes from the line of Rona Louise with Leerink Partners. Your line is open. Good afternoon, everyone. Thanks. So I was curious if you could discuss the European market opportunity for afikamtine a little bit and if there are any similarities or differences that we should think about versus the U.

Operator

S. And possible timeline for ramping up more of commercial presence in Europe?

Speaker 4

From a European point of view, you heard the filing dates, the prevalence in terms of the number of patients is slightly higher just because of the overall population is slightly higher. The price point is lower than the U. S, probably in the range of 15% to 25% depending on the country. From an opportunity point of view, once approval has occurred, we will launch in Germany that allows for launch and approval. Other markets need to submit, for reimbursement and pricing negotiation.

Speaker 4

So in general, Europe will probably be about a year behind in launch in terms of market opportunity outside of Germany.

Operator

Our next question comes from the line of Srikrita Debraukonda with Truist Securities. Your line is open.

Speaker 2

Hi, good afternoon.

Speaker 5

Good afternoon. This is Bilal on for Crippa. Is there anything in your data analysis to help predict who would be more susceptible to LVF drops in patients treated with afacamten? And would that be incorporated into your REMS program? And are you seeing stabilization of LVS over time?

Speaker 3

Well, the answer to the second part of your forest where you'll see EEF over time for up to a year, looks very stable. I think the question as to susceptibility factors, I think you can kind of predict, obviously who might have susceptibility. Those are patients that have after you finish titration, their EFs are 50%, 55%. They're maybe at more risk because they're closer to the cutoff. It's kind of obvious.

Speaker 3

And I think when you look at any sort of monitoring strategy that's employed in medicine, you generally look at patients that are closer to certain thresholds. You look at them more carefully than other patients who are more distant from it. So we'll certainly incorporate that into our thinking.

Speaker 2

Thank you. Very good. Thank you.

Operator

Our next question comes from the line of Jason Zumansky with Bank of America. Your line is open.

Speaker 2

Hello, Jason.

Speaker 13

Good afternoon. This is Cameron Bozog on for Jason. Congrats on the quarter and thanks for taking our question. How important to your commercial outlook is use in the community setting, especially when looking at the frontline opportunity? What do you think is necessary to make community prescribers feel more comfortable administering affi, especially given it's likely to have a REM?

Speaker 13

And then how long do you expect this transition to take? Thanks so much.

Speaker 4

When you're describing community, I'm assuming you still mean cardiology, community cardiology?

Speaker 13

Yes, exactly.

Speaker 4

There's a little over 1,000 prescribers now of CMI. When you look at claims data, there's probably around 10,000 cardiologists who drives diagnosis. About 80% of diagnosis is a smaller subset of general cardiology. Typically, specialty product launches always go from a core outward. That outward will occur over time.

Speaker 4

I do think the REMS probably slows it down a bit as education continues to occur. As patients start to show up in general cardiology already on a CMI, that will accelerate, especially in the maintenance phase. So hard to say exactly what that point will be, but it will certainly occur over time given the number of patients that need to be treated.

Operator

Our next question comes from the line of Serge Belanger with Needham. Your line is open.

Speaker 2

Good afternoon.

Speaker 14

I guess my question is regarding the upcoming SEQUOIA presentations. Maybe just talk about the decision to present at the heart failure meeting rather than the upcoming ACC meeting next month. And maybe what kind of additional data and analysis we'll see in those results? Thanks.

Speaker 2

Sure. I'll take that one. So we knew there was a risk when we top lined the results of Sequoia HCM that we may run afoul of a policy that ACC has regarding acceptance of abstracts, and what would be otherwise contained in the public domain when they have that abstract to review. We also knew we had a material obligation to shareholders to disclose that which we did choose to disclose. So our abstract for Sequoia was not accepted by ACC.

Speaker 2

We assume for the reasons that it was already disclosed in large detail in a press release. And therefore the next meeting is the HSA meeting a month later in May in Lisbon. So that's where these data we hope will be presented. That's still to be determined. But at the same time, we expect that it will be presented and potentially published concurrently in and around the Q2.

Speaker 2

So I hope that answers your question, but we expect not just will these primary efficacy and safety results be presented and published, but more so in connection with other secondary analyses and also some post hoc analyses. We believe we've got an aggressive communications plan with regard to presentations and publications and you'll see multiple presentations and publications during that period.

Speaker 14

Thanks. Look forward to seeing the additional data.

Speaker 2

Thank you.

Operator

Our next question comes from the line of Charles Duncan with Cantor Fitzgerald. Your line is open. Hey,

Speaker 15

good afternoon. Hey, Robert and team, congrats on all the progress. Thanks for taking our questions. ACC seems a little shortsighted on that last point. Wanted to ask you a couple of quick questions that you may not be able to answer.

Speaker 15

And one is kind of simple and that is, do you anticipate an adcom to be called? And the second is harder to answer and that is, what compels you more, pharmacoeconomic modeling supportive of say premium pricing or an anchor to a standard of care? I know you're not really talking about pricing, but just your perspective.

Speaker 2

So as it relates to an AdCom, we can't know that. What we do know is that there was not an AdCom for mavacamten. That doesn't necessarily mean we wouldn't have an AdCom. We'll be prepared if there is an AdCom, but that's not something that one can know at this juncture and certainly not until a submission is accepted for filing. As it relates to what we're compelled by in connection with pricing, I'm not going to speak to the pricing, but I will say we're quite compelled by what are the HEOR data sets that are being prepared and analyzed and how they relate to value associated with affecamten.

Speaker 2

And that alongside of a number of other factors ultimately contribute to what will be determinants of pricing. I think that's the best I can do for you today. Perfect.

Speaker 15

Looks like an interesting year. Thanks for taking the questions.

Speaker 2

Thanks, Charles.

Operator

And I'm showing no further questions at this time. I would now like to turn the conference back to Robert Blum, President and CEO, for closing remarks.

Speaker 2

Thank you, operator. We covered a lot of ground today, both in our prepared comments and also in our Q and A, so I'll be brief. I'll simply say that with Sequoia results, we do believe we've turned an important page onto the next chapter for Cytokinetics and we'll remain vigilant with regard to execution and doing right by shareholders. At the same time, we're humbled by the science, but also we're leaning forward on the opportunity that Afikampton presents, not just as it relates to OHCM, but also as it opens a door, we believe, on other value creation. We'll look forward to keeping shareholders abreast of that progress.

Speaker 2

And with that, operator, we can now conclude the call, please.
