Cytokinetics Announces Date for FDA Advisory Committee Meeting to Review New Drug Application for Omecamtiv Mecarbil
Cytokinetics announced that the FDA will review its New Drug Application for omecamtiv mecarbil during a meeting on December 13, 2022. This investigational drug aims to treat heart failure with reduced ejection fraction (HFrEF). The FDA's PDUFA target action date is set for February 28, 2023. The drug has shown positive results in the GALACTIC-HF clinical trial, significantly reducing cardiovascular deaths and heart failure events. Cytokinetics is preparing for potential commercialization following this approval process.
- FDA review scheduled for December 13, 2022, increases visibility for omecamtiv mecarbil.
- PDUFA action date set for February 28, 2023, indicating a fast-tracked process.
- Positive Phase 3 trial results from GALACTIC-HF showing reduced cardiovascular events.
- No significant reduction in secondary endpoint of time to CV death observed in clinical trials.
Meeting Currently Scheduled for December 13, 2022
SOUTH SAN FRANCISCO, Calif., June 24, 2022 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (Nasdaq: CYTK) today announced that the U.S. Food and Drug Administration (FDA) has informed the company that the previously announced meeting of the Cardiovascular and Renal Drugs Advisory Committee to review the New Drug Application for omecamtiv mecarbil is currently scheduled for December 13, 2022. The FDA has assigned the NDA a Prescription Drug User Fee Act (PDUFA) target action date of February 28, 2023. Omecamtiv mecarbil is an investigational, selective, small molecule cardiac myosin activator for the treatment of heart failure with reduced ejection fraction (HFrEF).
“Patients with heart failure with reduced ejection fraction remain at high risk for hospitalization and clinical events despite available therapies,” said Robert I. Blum, Cytokinetics’ President and Chief Executive Officer. “We look forward to the opportunity to discuss the underlying science and evidence arising from our development program for omecamtiv mecarbil with the FDA and the Advisory Committee.”
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 is assessing 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. The FDA has accepted for filing the NDA for omecamtiv mecarbil based on the results from GALACTIC-HF and has assigned a Prescription Drug User Fee Act (PDUFA) date of February 28, 2023.
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-generation 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.
