Authors' conclusion
Among high-risk adults with pulmonary arterial hypertension who were receiving the maximum tolerated dose of background therapy, treatment with sotatercept resulted in a lower risk of a composite of death from any cause, lung transplantation, or hospitalization (≥24 hours) for worsening pulmonary arterial hypertension than placebo.
