Omecamtiv mecarbil is being developed for the potential treatment of heart failure with reduced ejection fraction (HFrEF).

METEORIC-HF is designed to evaluate the effect of treatment with omecamtiv mecarbil compared to placebo on exercise capacity as determined by cardiopulmonary exercise testing (CPET) in patients with HFrEF. Cytokinetics is conducting METEORIC-HF in collaboration with Amgen, with funding and strategic support from Servier.

“The start of this second Phase 3 clinical trial marks an important milestone in the expansion of our clinical trials program for omecamtiv mecarbil, testing the hypothesis that improving cardiac function with a drug candidate that directly increases myocardial contractility may improve exercise capacity,” said Fady I. Malik, M.D., Ph.D., executive vice president of Research & Development at Cytokinetics. “Exercise intolerance, typically manifested by shortness of breath and fatigue on exertion, is a predominant symptom of chronic heart failure and often the first symptom that prompts patients to seek medical care. If positive, this clinical trial may provide key clinically relevant evidence.”

METEORIC-HF Clinical Trial Design

METEORIC-HF is a Phase 3, randomized, placebo-controlled, double-blind, parallel group, multicenter clinical trial designed to evaluate the effect of treatment with omecamtiv mecarbil compared to placebo on exercise capacity as determined by cardiopulmonary exercise testing (CPET) following 20 weeks of treatment. The trial is designed to enroll approximately 270 patients with HFrEF at sites throughout the U.S., Canada and Europe. In order to be eligible to participate in METEORIC-HF, patients must have a left ventricular ejection fraction (LVEF) ≤35 percent, be New York Heart Association (NYHA) heart failure class II or III and have reduced exercise capacity compared to age matched controls. Patients will be randomized in a 2:1 fashion to omecamtiv mecarbil, which will be started at 25 mg twice daily and titrated to 25, 37.5 or 50 mg twice daily based on the same PK-guided dosing regimen as is used in GALACTIC-HF, the ongoing Phase 3 cardiovascular outcomes trial of omecamtiv mecarbil, or to placebo. The primary endpoint is the change in peak oxygen uptake (pVO2) on CPET from baseline to Week 20. Secondary endpoints include the change in total workload during CPET from baseline to Week 20 and the change in the average daily activity units measured over a 2-week period from baseline (Week -2 to Day 1) to Week 18-20 as determined using accelerometry.
