Q & A Highlights

Q: Based on the Phase 1 results released this morning, what will be the starting dose and escalation strategy for the Phase 2 clinical study of CK-586? How do you plan to monitor for safety and efficacy in this study? A: Robert I. Blum, CEO & President of Cytokinetics, noted that it's premature to announce the design for the Phase 2 study. Fady Ibraham Malik, EVP of Research & Development, added that all doses in the press release were well tolerated, and Phase 2 will primarily be a dose-finding study in patients with heart failure and preserved ejection fraction. Specific details on monitoring and dosing schedules will be disclosed later.

Q: Regarding MAPLE-HCM, do you have any plans to submit any interim or partial cut of the data as part of your NDA filing to bolster your case for your proposed REMS and/or label? A: Fady Ibraham Malik explained that MAPLE-HCM will remain blinded until it reads out in 2025. However, during the NDA review, a 120-day safety update will be submitted, including aggregate safety data from ongoing trials like MAPLE and ACACIA, as well as updated safety and efficacy data from FOREST-HCM.

Q: With aficamten still in early stages of launch, what is the potential for patients to switch from mavacamten to aficamten? A: Robert I. Blum mentioned that while it's possible some patients might switch due to concerns over safety or efficacy, the primary strategy is to expand the category for aficamten. Andrew M. Callos, EVP & Chief Commercial Officer, emphasized focusing on educating physicians and broadening cardiology awareness rather than promoting patient switches.

Q: Can you discuss the unmet need for an agent like aficamten in the pediatric segment of the HCM market, particularly regarding the CEDAR-HCM trial? A: Fady Ibraham Malik highlighted the significant unmet need in pediatric HCM, noting that available treatment options are limited, especially surgery. The potential availability of a myosin inhibitor like aficamten could be quite meaningful for this demographic, which often experiences aggressive disease progression.

Q: What are your latest thoughts on the potential for a priority review or an AdCom for aficamten? A: Robert I. Blum stated that neither a priority review nor an AdCom is assumed in their base case. While a priority review is possible, it is not expected, and an AdCom would be unusual given the compelling data and the presence of another effective cardiac myosin inhibitor in the market that did not require an AdCom.

Q: Regarding the additional data to be presented at the upcoming ESC Heart Failure Congress, do you believe it will become clear that aficamten wins on efficacy, not just on its safety profile? A: Robert I. Blum clarified that while aficamten was not directly compared to mavacamten, the data from SEQUOIA-HCM support its profile in terms of efficacy, safety, and convenience. He expressed confidence that the full data would reaffirm expectations that aficamten could become the cardiac myosin inhibitor of choice if approved.
