FDA grants fast Track designation to omecamtiv mecarbil for HFrEF
THOUSAND OAKS, Calif. and SOUTH SAN FRANCISCO--Heart failure is a serious condition that affects more than 64 million people worldwide about half of whom have reduced left ventricular function. It is the leading cause of hospitalization and readmission in people age 65 and older. The researchers are always in look out for new drugs to manage
The U.S. Food and Drug Administration (FDA) has granted Fast Track designation for omecamtiv mecarbil to be developed for the potential treatment of chronic heart failure with reduced ejection fraction (HFrEF).
Omecamtiv mecarbil is a novel, selective cardiac myosin activator, also known as a cardiac myotrope, that binds to the catalytic domain of myosin.
Preclinical research has shown that omecamtiv mecarbil increases cardiac contractility without increasing intracellular myocyte calcium concentrations or myocardial oxygen consumption. Cardiac myosin is the cytoskeletal motor protein in the cardiac muscle cell that is directly responsible for converting chemical energy into the mechanical force resulting in cardiac contraction.
Omecamtiv mecarbil is being developed for the potential treatment of heart failure with reduced ejection fraction (HFrEF) under a collaboration between Amgen and Cytokinetics, with funding and strategic support from Servier.
The fast Track designation may potentially expedite the review of a drug that is intended for the treatment of a serious or life-threatening disease or condition and demonstrates the potential to address an unmet medical need for such a disease or condition.
"This Fast Track designation represents an important milestone in the development of omecamtiv mecarbil," said David M. Reese, M.D., executive vice president of Research and Development at Amgen. "Today, half of heart failure patients will die within five years of diagnosis, underscoring the urgent need for new therapies for this grievous condition."
"We are pleased that the FDA has granted Fast Track designation for omecamtiv mecarbil for the potential treatment of heart failure," said Robert I. Blum, president and chief executive officer of Cytokinetics. "The prevalence of heart failure is growing with our aging demographics, and GALACTIC-HF is designed to assess the clinical effects of our novel myosin activator in patients meaningfully at risk."
GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure), one of the largest Phase 3 global cardiovascular (CV) outcomes studies in heart failure ever conducted, is designed to evaluate whether treatment with omecamtiv mecarbil, when added to standard of care, reduces the risk of heart failure events (heart failure hospitalization and other urgent treatment for heart failure) and CV death in patients with HFrEF. GALACTIC-HF enrolled 8,256 patients in 35 countries who were either hospitalized at the time of enrollment for a primary reason of heart failure or had a hospitalization or admission to an emergency room for heart failure within one year prior to screening. Dose selection for omecamtiv mecarbil in this study uses a blood test. Top-line results from GALACTIC-HF are expected in Q4 2020.
