• Merck's Phase 3 HYPERION trial of Winrevair (sotatercept) for pulmonary arterial hypertension (PAH) is stopped early due to positive results from the ZENITH trial.
• The decision, made with the FDA and a steering committee, allows all HYPERION participants access to Winrevair in the SOTERIA extension study.
• Winrevair, already approved in the U.S. and 38 countries, showed significant efficacy in the STELLAR and ZENITH trials, leading to the HYPERION halt.
• HYPERION findings will be available later this year, adding to the growing evidence supporting Winrevair's role in PAH treatment.
