Cytokinetics Announces Positive Topline Results From MAPLE-HCM
Trial Demonstrates Superiority of Aficamten to Standard of Care Beta Blocker in Improving Peak Exercise Capacity in Patients with Obstructive Hypertrophic Cardiomyopathy SOUTH SAN FRANCISCO, Calif., May 13, 2025 (GLOBE NEWSWIRE) — Cytokinetics, Incorporated (Nasdaq: CYTK) today announced positive topline results from MAPLE-HCM (Metoprolol vs Aficamten in Patients with LVOT Obstruction on Exercise Capacity in HCM), a Phase 3 clinical trial comparing aficamten as monotherapy to the standard of care beta blocker metoprolol as monotherapy in patients with symptomatic obstructive hypertrophic cardiomyopathy (HCM). MAPLE-HCM met its primary endpoint, demonstrating a statistically significant improvement in peak oxygen uptake (pVO2) from baseline to Week 24 for aficamten compared to metoprolol. The safety and tolerability profile of aficamten was favorable in comparison to metoprolol in MAPLE-HCM. The full results from MAPLE-HCM will be presented at an upcoming medical conference. “These results represent the first evidence that aficamten may be used as monotherapy to deliver clinically meaningful improvements in people living with obstructive hypertrophic cardiomyopathy,” said Fady I. Malik, M.D., Ph.D., Cytokinetics’ Executive Vice President of Research & Development. “Importantly, the results from MAPLE-HCM provide important context to the benefit of this potential new medicine compared to the current standard of care. We are grateful to the investigators, site personnel and patients who participated in MAPLE-HCM, and look forward to presenting the full results at an upcoming medical meeting.” MAPLE-HCM: Clinical Trial Design MAPLE-HCM was a Phase 3, multi-center, randomized, double-blind active-comparator clinical trial of aficamten compared to metoprolol in patients with symptomatic obstructive HCM. The primary endpoint was the change in peak oxygen uptake (pVO2) from baseline to Week 24 measured by cardiopulmonary exercise testing (CPET). Secondary endpoints include the change from baseline to Week 24 in Kansas City Cardiomyopathy Questionnaire (KCCQ) score, the proportion of patients with ≥1 class improvement in New York Heart Association (NYHA) functional class, and changes in left ventricular mass index (LVMI), left atrial volume index (LAVI), post-Valsalva left ventricular outflow tract gradient (LVOT-G) and NT-proBNP. MAPLE-HCM enrolled 175 patients, randomized on a 1:1 basis to receive aficamten or metoprolol as monotherapy in a double-blind, double dummy fashion. Randomization was stratified by CPET exercise modality (treadmill or bicycle) and recently diagnosed versus chronic obstructive HCM. At screening, patients enrolled in MAPLE-HCM had a resting LVOT-G ≥30 mmHg and/or post-Valsalva LVOT-G ≥50 mmHg in addition to left ventricular ejection fraction (LVEF) ≥ 60%, respiratory exchange ratio (RER) ≥ 1.05 and pVO2
Cytokinetics Announces New PDUFA Date for Aficamten in Obstructive Hypertrophic Cardiomyopathy
SOUTH SAN FRANCISCO, Calif., May 01, 2025 (GLOBE NEWSWIRE) — Cytokinetics, Incorporated (Nasdaq: CYTK) today announced that the U.S. Food and Drug Administration (FDA) has extended the Prescription Drug User Fee Act (PDUFA) action date for the New Drug Application (NDA) for aficamten for the treatment of patients with obstructive hypertrophic cardiomyopathy (oHCM) to December 26, 2025. The FDA recently notified Cytokinetics that additional time is required to conduct a full review of the company’s proposed Risk Evaluation and Mitigation Strategy (REMS). Following pre-NDA discussions with FDA in which safety and risk mitigation were discussed, Cytokinetics submitted the NDA for aficamten in oHCM without an accompanying REMS, and the FDA accepted the NDA for filing. Recently, during the NDA review, the FDA requested that Cytokinetics submit a REMS, based on the inherent characteristics of aficamten, which the company provided. The submission of a REMS has now been determined by FDA to be a Major Amendment to the NDA resulting in a standard three-month extension to the original PDUFA action date. No additional clinical data or studies have been requested of Cytokinetics by FDA. “We remain confident in the distinct benefit-risk and pharmaceutic profile of aficamten and continue to expect a differentiated label and risk mitigation profile upon its potential approval by FDA,” said Robert I. Blum, Cytokinetics’ President and Chief Executive Officer. “We look forward to continuing our constructive engagement with the FDA regarding the NDA for aficamten.” 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 Announces Five Presentations at the American College of Cardiology Annual Scientific Session & Expo
New Analyses Related to Aficamten Expand on its Metabolism Pathways,Treatment Effect Associated with Combination Therapy with Disopyramideand Longer-Term Effect on Cardiac Structure and Function SOUTH SAN FRANCISCO, Calif., March 17, 2025 (GLOBE NEWSWIRE) — Cytokinetics, Incorporated (Nasdaq: CYTK) today announced five presentations related to aficamten, an investigational cardiac myosin inhibitor, and hypertrophic cardiomyopathy (HCM), at the American College of Cardiology (ACC) Annual Scientific Session & Expo taking place from March 29, 2025–March 31, 2025 in Chicago, IL. “We are pleased to be sharing several new analyses relating to aficamten at the upcoming ACC Scientific Session & Expo,” said Stephen Heitner, M.D., Vice President, Head of Clinical Research. “The presentations describe the drug metabolism of aficamten, the safety of combination therapy with the standard of care medication disopyramide, and the effect of longer-term use of aficamten. Together these analyses add to the strong and growing evidence base supporting the potential for aficamten in patients with obstructive HCM and inform how it may be used in clinical practice.” Evaluation of Cytochrome P450 2C9, 2C19, and 2D6 Inhibition on the Pharmacokinetics of Aficamten in Healthy Participants (1091-139)Poster Presentation, March 29, 2025, 2:00-3:00 PM CT, South Hall. Neha Maharao, Ph.D., Senior Clinical Pharmacologist, Cytokinetics. Data from an open-label, fixed-sequence drug-drug interaction (DDI) study of aficamten in healthy participants will be presented in a poster presentation. A previous study showed that aficamten is metabolized, in part, by the cytochrome P450 (CYP) enzyme 3A41. To further characterize its metabolic pathways, aficamten was evaluated with concomitant administration of three strong inhibitors of one or more of the CYP pathways: fluconazole (inhibitor of 2C9, 2C19, and 3A4), paroxetine (inhibitor of 2D6) and fluoxetine (inhibitor of 2C19 and 2D6). The data show that aficamten was eliminated by multiple CYP pathways, primarily by CYP2C9 (fraction metabolized [fm]=50%), with contributions from CYP3A (fm=26%), CYP2D6 (fm=21%) and CYP2C19 (fm=3%). Safety and Outcomes of Concomitant Aficamten and Disopyramide Use and Withdrawal in Patients with Obstructive Hypertrophic Cardiomyopathy: An Analysis of REDWOOD-HCM Cohort 3, SEQUOIA-HCM, and FOREST-HCM Trials (411-06)Oral Presentation, March 31, 2025, 9:11-9:18 AM CT, S406b. Ahmad Masri, M.D., MS, Director of the Hypertrophic Cardiomyopathy Center at Oregon Health & Science University. Data from an analysis of concomitant treatment with aficamten and disopyramide from completed and ongoing clinical trials of aficamten in patients with obstructive HCM will be presented in an oral presentation. The analysis included 50 participants from Cohort 3 of REDWOOD-HCM (Randomized Evaluation of Dosing With CK-274 in Obstructive Outflow Disease in HCM), SEQUOIA-HCM (Safety, Efficacy, and Quantitative Understanding of Obstruction Impact of Aficamten in HCM) and FOREST-HCM (Follow-up, Open-Label, Research Evaluation of Sustained Treatment with Aficamten in HCM) who were receiving disopyramide at baseline. Participants were separated into four groups: those on disopyramide who underwent withdrawal of aficamten due to end of treatment in Cohort 3 of REDWOOD-HCM or SEQUOIA-HCM (n=29), patients on disopyramide receiving placebo in SEQUOIA-HCM (n=20), patients on aficamten who underwent disopyramide withdrawal in FOREST-HCM (n=17) and patients on aficamten who maintained treatment with disopyramide in FOREST-HCM (n=27). Combination therapy with aficamten and disopyramide was well-tolerated; the analysis suggests that combination of disopyramide with aficamten did not result in lower left ventricular outflow tract (LVOT) gradients compared to treatment with aficamten alone. The analysis suggests that withdrawal of disopyramide while receiving aficamten did not reduce the efficacy of aficamten and further that withdrawal of aficamten while on disopyramide resulted in the return of LVOT obstruction and symptoms, with an increase in NT-proBNP. There were no safety events reported with either aficamten or disopyramide withdrawal, and no episodes of atrial fibrillation after disopyramide withdrawal were reported. Effect of Aficamten Treatment for Up to 72 Weeks on Cardiac Structure and Function in Patients with Obstructive Hypertrophic Cardiomyopathy: The SEQUOIA-HCM and FOREST-HCM CMR Sub-studies (964-09)Moderated Poster Presentation, March 30, 2025, 12:06-12:13 PM CT, Theater 5. Ahmad Masri, M.D., MS, Director of the Hypertrophic Cardiomyopathy Center at Oregon Health & Science University. New data from the cardiac magnetic resonance (CMR) imaging sub-studies of FOREST-HCM and SEQUOIA-HCM will be presented in a moderated poster presentation. At the time of the current analysis, 64 patients had completed a baseline CMR, including 36 patients who had completed a follow-up CMR at 72 weeks, and 28 patients who had completed a follow-up CMR at 48 weeks. Longer-term treatment with aficamten resulted in statistically significant improvements (mean ±SD) in measures of cardiac structure and function including left ventricular mass index (-9.8 g/m2 ±18.1, p
