European Launch Follows Strong U.S. Start

SOUTH SAN FRANCISCO, Calif., and ZUG, Switzerland, June 01, 2026 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (NASDAQ:CYTK) today announced the first commercial European launch of MYQORZO® (aficamten) in Germany for the treatment of symptomatic (New York Heart Association, NYHA, class II-III) obstructive hypertrophic cardiomyopathy (oHCM) in adult patients. MYQORZO is an allosteric and reversible inhibitor of cardiac myosin motor activity. In patients with oHCM, myosin inhibition reduces cardiac contractility and consequently, left ventricular outflow tract (LVOT) obstruction.

Marking the first of several planned European launches, the availability of MYQORZO in Germany follows the European Commission approval in February 2026. The approval was based on positive results from SEQUOIA-HCM, the pivotal Phase 3 clinical trial of aficamten in patients with oHCM, demonstrating robust efficacy, safety, and clinically meaningful benefits across symptoms, exercise capacity, hemodynamics, and biomarker endpoints.1 These clinical results were published in the New England Journal of Medicine.
