Cytokinetics Announces FDA Acceptance of New Drug Application for Omecamtiv Mecarbil for the Treatment of Heart Failure With Reduced Ejection Fraction
PDUFA Target Action Date Set for
FDA is Currently Not Planning to Hold an Advisory Committee Meeting to Discuss the Application
The FDA assigned the NDA a standard review with a Prescription Drug User Fee Act (PDUFA) target action date of
“This is an exciting milestone and important next step towards the commercial launch of omecamtiv mecarbil,” said
The NDA is supported by the results from GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure), the Phase 3 cardiovascular outcomes clinical trial of omecamtiv mecarbil that enrolled over 8,000 patients in 35 countries across 945 sites. GALACTIC-HF 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. Additional analyses from GALACTIC-HF demonstrated a greater treatment effect of omecamtiv mecarbil in patients with lower left ventricular ejection fraction (LVEF), as well as other characteristics that may indicate worsening heart failure.
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. METEORIC-HF, a second Phase 3 clinical trial of omecamtiv mecarbil is designed to evaluate the effect of treatment with omecamtiv mecarbil compared to placebo on exercise capacity. Results from METEORIC-HF are expected in early 2022.
