Study Design and Objectives

The Proof-of-Concept study enrolled 75 adults with moderate-to-severe HHT across the United States and European sites. Participants were randomized to receive oral engasertib (30 mg, 40 mg) or placebo for 12 weeks, followed by a long-term open-label extension. (ClinicalTrials.gov Identifier: NCT05406362)
