FDA Advisory Committee to Review the New Drug Application for Omecamtiv Mecarbil for the Treatment of Heart Failure with Reduced Ejection Fraction

SOUTH SAN FRANCISCO, Calif., Dec. 13, 2022 (GLOBE NEWSWIRE) — Cytokinetics, Incorporated (Nasdaq: CYTK) today announced that Nasdaq has halted the trading of the Company’s common stock. The U.S. Food & Drug Administration (FDA) Cardiovascular and Renal Drugs Advisory Committee (CRDAC) is meeting today to review the New Drug Application (NDA) for omecamtiv mecarbil, an investigational selective, small molecule cardiac myosin activator for the treatment of heart failure with reduced ejection fraction (HFrEF).

The advisory committee meeting, which is being held virtually, is scheduled to begin at 9:00 AM ET today. Briefing materials and webcast information for the meeting can be accessed at https://www.fda.gov/advisory-committees/advisory-committee-calendar/december-13-2022-cardiovascular-and-renal-drugs-advisory-committee-meeting-announcement-12132022. The Company is not responsible for the content of, nor the statements made in, the briefing materials that were prepared by the FDA.

The NDA for omecamtiv mecarbil is based on the results from GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure), the Phase 3 clinical trial of omecamtiv mecarbil. The Prescription Drug User Fee Act (PDUFA) target action date for the NDA is February 28, 2023.

About Omecamtiv Mecarbil

Omecamtiv mecarbil is an investigational, selective, small molecule cardiac myosin activator, the first of a novel class of myotropes¹ designed to directly target the contractile mechanisms of the heart, binding to and recruiting more cardiac myosin heads to interact with actin during systole. Omecamtiv mecarbil is designed to increase the number of active actin-myosin cross bridges during each cardiac cycle and consequently augment the impaired contractility that is associated with heart failure with reduced ejection fraction (HFrEF). Preclinical research has shown that omecamtiv mecarbil increases cardiac contractility without increasing intracellular myocyte calcium concentrations or myocardial oxygen consumption.^2-4

The development program for omecamtiv mecarbil assessed its potential for the treatment of HFrEF. Positive results from GALACTIC-HF, the first Phase 3 clinical trial of omecamtiv mecarbil demonstrated a statistically significant effect of treatment with omecamtiv mecarbil to reduce risk of the primary composite endpoint of cardiovascular (CV) death or heart failure events (heart failure hospitalization and other urgent treatment for heart failure) compared to placebo in patients treated with standard of care. No reduction in the secondary endpoint of time to CV death was observed. Adverse events and treatment discontinuation of study drug were balanced between treatment arms.

About Heart Failure

Heart failure is a grievous condition that affects more than 64 million people worldwide⁵ about half of whom have reduced left ventricular function.^6,7 It is the leading cause of hospitalization and readmission in people age 65 and older.^8,9 Despite broad use of standard treatments and advances in care, the prognosis for patients with heart failure is poor.¹⁰ An estimated one in five people over the age of 40 are at risk of developing heart failure, and approximately 50 percent of people diagnosed with heart failure will die within five years of initial hospitalization.^11,12 Approximately 2 million people in the U.S. are estimated to have an ejection fraction ≤30%, indicating they may have worsening heart failure.¹³

About Cytokinetics

Cytokinetics is a late-stage biopharmaceutical company focused on discovering, developing and commercializing first-in-class muscle activators and next-in-class muscle inhibitors as potential treatments for debilitating diseases in which muscle performance is compromised. As a leader in muscle biology and the mechanics of muscle performance, the company is developing small molecule drug candidates specifically engineered to impact muscle function and contractility. Cytokinetics is readying for the potential commercialization of omecamtiv mecarbil, its cardiac muscle activator, following positive results from GALACTIC-HF, a large, international Phase 3 clinical trial in patients with heart failure. Cytokinetics is also developing aficamten, a next-in-class cardiac myosin inhibitor, currently the subject of SEQUOIA-HCM, the Phase 3 clinical trial of aficamten in patients with symptomatic obstructive hypertrophic cardiomyopathy (HCM). Aficamten is also being evaluated in non-obstructive HCM in Cohort 4 of the Phase 2 clinical trial, REDWOOD-HCM. Cytokinetics is also developing reldesemtiv, an investigational fast skeletal muscle troponin activator, currently the subject of COURAGE-ALS, a Phase 3 clinical trial in patients with amyotrophic lateral sclerosis (ALS). Cytokinetics continues its over 20-year history of pioneering innovation in muscle biology and related pharmacology focused to diseases of muscle dysfunction and conditions of muscle weakness.
