Regulatory Reviews of Aficamten for Obstructive HCM Progressing in U.S., E.U. and China; Late-Cycle Meeting with U.S. FDA Scheduled for September Ahead of December 26, 2025 PDUFA Date

Primary Results from MAPLE-HCM to be Presented in a Hot Line Session at the European Society of Cardiology Congress 2025

~$1.0 Billion in Cash, Cash Equivalents and Investments as of June 30, 2025

SOUTH SAN FRANCISCO, Calif., Aug. 07, 2025 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (Nasdaq: CYTK) reported a management update and financial results for the second quarter of 2025.

“Following solid progress in the first half of the year, we are looking forward to several key corporate milestones. Our primary focus remains on preparations for the potential FDA approval of aficamten in late December and subsequent commercial launch in early 2026,” said Robert I. Blum, Cytokinetics’ President and Chief Executive Officer. “Additionally, we are pleased to be sharing results from MAPLE-HCM later this month, which we believe will provide important information related to the standard-of-care in obstructive HCM. With our current balance sheet and additional access to capital, we are well-positioned to execute on both the commercialization and potential label expansion opportunities of aficamten while also advancing our later-stage specialty cardiovascular pipeline.”

Q2 and Recent Highlights

Cardiac Muscle Programs

aficamten (cardiac myosin inhibitor)

  • Continued to support the review of the New Drug Application (NDA) for aficamten for the treatment of patients with obstructive hypertrophic cardiomyopathy (HCM) by the U.S. Food and Drug Administration (FDA). With the three-month extension of the Prescription Drug User Fee Act (PDUFA) target action date to December 26, 2025, the late cycle meeting is now scheduled to occur in September.

  • Prepared responses to the Day 120 List of Questions from the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) regarding the Marketing Authorization Application (MAA) for aficamten for the treatment of obstructive HCM; submission on track to meet the clock stop timeline agreed with EMA. We expect a potential EMA decision regarding the MAA in 1H 2026.

  • Completed all Good Clinical Practice (GCP) inspections for applications under review.

  • Continued to support the review of the NDA for aficamten for obstructive HCM by the Center for Drug Evaluation (CDE) in China.

  • Advanced the ongoing clinical trials program for aficamten:
    • Announced positive topline results from MAPLE-HCM (Metoprolol vs Aficamten in Patients with LVOT Obstruction on Exercise Capacity in HCM). The primary results will be presented in a Hot Line Session in August at the European Society of Cardiology Congress 2025.

    • Continued conduct of ACACIA-HCM (Assessment Comparing Aficamten to Placebo on Cardiac Endpoints In Adults with Non-Obstructive HCM), a pivotal Phase 3 clinical trial of aficamten in patients with non-obstructive HCM. We expect to share topline results of the primary cohort (excluding Japan) in 1H 2026. Dosed the first patient in the Japan cohort of ACACIA-HCM.

    • Dosed the first patient in CAMELLIA-HCM, a Phase 3 clinical trial of aficamten in Japanese patients with obstructive HCM. CAMELLIA-HCM is being conducted by Bayer in collaboration with Cytokinetics to support potential marketing authorization in Japan.

    • Continued enrolling patients in CEDAR-HCM (Clinical Evaluation of Dosing with Aficamten to Reduce Obstruction in a Pediatric Population in HCM), a clinical trial of aficamten in a pediatric population with symptomatic obstructive HCM. We expect to complete patient enrollment of the adolescent cohort in 2H 2025.

  • Presented new analyses at the European Society of Cardiology Heart Failure 2025 Congress from SEQUOIA-HCM on the effect of aficamten between patients with mild and moderate-to-severe symptoms, and across geographic regions.

  • Expanded U.S. commercial readiness activities for aficamten including sales force recruitment, final stages of implementing patient support programs and finalization of our promotional launch campaign. Continued payer engagement to educate on the clinical data supportive of aficamten and the clinical and economic burden of HCM.

  • Advanced European commercial readiness activities including hiring key leadership positions in our European headquarters and other EU and UK geographies, preparing Health Technology Assessment (HTA) dossiers and ensuring launch readiness for potential approval in Germany in 1H 2025.

  • Published the following manuscripts:
    • “A Plain Language Summary of the SEQUOIA-HCM Study: Aficamten for Symptomatic Obstructive Hypertrophic Cardiomyopathy” in Future Cardiology
    • “Efficacy of Aficamten in Patients with Obstructive Hypertrophic Cardiomyopathy and Mild Symptoms: Results from the SEQUOIA-HCM Trial” in the European Heart Journal
    • “Associations of Sex on Economic Burden in Patients with Symptomatic Obstructive Hypertrophic Cardiomyopathy: Results from Medical and Pharmacy Claims Data in Frontiers in Cardiovascular Medicine
    • “Aficamten Treatment for Symptomatic Obstructive Hypertrophic Cardiomyopathy: 48-weeks Results From FOREST-HCM” in the Journal of the American College of Cardiology – Heart Failure
    • “Concomitant Aficamten and Disopyramide in Symptomatic Obstructive Hypertrophic Cardiomyopathy” in the Journal of the American College of Cardiology – Heart Failure
    • “Clinical Evaluation of the Effect of Aficamten on QT/QTc Interval in Healthy Participants” in Clinical and Translational Science

omecamtiv mecarbil (cardiac myosin activator)

  • Continued conduct of COMET-HF (Confirmation of Omecamtiv Mecarbil Efficacy Trial in Heart Failure), a confirmatory Phase 3 clinical trial of omecamtiv mecarbil in patients with symptomatic heart failure with severely reduced ejection fraction. We expect to continue enrollment through 2025 to enable completion of enrollment in late 2026.

ulacamten (CK-4021586, cardiac myosin inhibitor)

  • Received approval from the International Nonproprietary Names (INN) Program of the World Health Organization for ulacamten to be used as the nonproprietary name for CK-4021586.

  • Continued conduct of AMBER-HFpEF (Assessment of CK-586 in a Multi-Center, Blinded Evaluation of Safety and Tolerability Results in HFpEF), a Phase 2 clinical trial of ulacamten in patients with symptomatic heart failure with preserved ejection fraction (HFpEF) with left ventricular ejection fraction (LVEF) ≥ 60%. We expect to complete patient enrollment of the first two cohorts in 2H 2025.

Pre-Clinical Development and Ongoing Research

  • Continued pre-clinical development and research activities directed to additional muscle biology focused programs.

Second Quarter 2025 Financial Results

About Cytokinetics

Cytokinetics is a specialty cardiovascular biopharmaceutical company, building on its over 25 years of pioneering scientific innovations in muscle biology to advance a pipeline of potential new medicines for patients suffering from diseases of cardiac muscle dysfunction. Cytokinetics is readying for potential regulatory approvals and commercialization of aficamten, a cardiac myosin inhibitor following positive results from SEQUOIA-HCM, the pivotal Phase 3 clinical trial in patients with obstructive hypertrophic cardiomyopathy (HCM). Aficamten is also being evaluated in additional clinical trials enrolling patients with obstructive and non-obstructive HCM. Cytokinetics is also developing omecamtiv mecarbil, a cardiac myosin activator, in patients with heart failure with severely reduced ejection fraction (HFrEF), ulacamten, a cardiac myosin inhibitor with a mechanism of action distinct from aficamten, for the potential treatment of heart failure with preserved ejection fraction (HFpEF) and CK-089, a fast skeletal muscle troponin activator with potential therapeutic application to a specific type of muscular dystrophy and other conditions of impaired skeletal muscle function.
