Cytokinetics said Tuesday that its drug Myqorzo significantly improved heart failure symptoms and cardiovascular fitness in patients with non-obstructive hypertrophic cardiomyopathy, an inherited heart disorder. The results, reported in a company press release, achieved the dual efficacy goals of a Phase 3 clinical trial, called ACACIA, with statistical significance.Advertisement Cytokinetics is in the early days of Myqorzo’s commercial launch as a treatment for the more severe “obstructive” form of hypertrophic cardiomyopathy, or HCM.
