The Astellas OSSA Agreement was terminated effective November 1, 2021, ending Astellas' rights to co-develop skeletal sarcomere activators[193] Safety and Efficacy Results - Amgen and Servier announced that treatment with omecamtiv mecarbil achieved a statistically significant reduction in cardiovascular death or heart failure events, with a hazard ratio of 0.92 (95% CI: 0.86, 0.99, p=0.025) in the GALACTIC-HF trial[144] - The GALACTIC-HF trial enrolled 8,256 patients with symptomatic chronic heart failure, demonstrating a primary endpoint event in 37.0% of the omecamtiv mecarbil group compared to 39.1% in the placebo group[156] - No significant reduction in the secondary endpoint of cardiovascular death was observed, with 19.6% of patients in the omecamtiv mecarbil group and 19.4% in the placebo group experiencing this outcome[159] - Omecamtiv mecarbil significantly decreased NT-proBNP concentrations by 10% (95% CI 6-14%) at Week 24 compared to placebo[160] - The overall safety profile of omecamtiv mecarbil was consistent with previous trials, with balanced rates of adverse events between treatment arms[161] -
