Recruiting at 1 site Phase 4 Pulmonary Artery Hypertension

Pulmonary Artery Hypertension study: Sotatercept

Official title Sotatercept in Pulmonary Arterial Hypertension

ClinicalTrials.gov ID: NCT07140484

What this study is testing

What is Sotatercept?

An investigational injectable medicine being studied as a potential treatment for pulmonary arterial hypertension. It is designed to bind activin and related proteins, modulating TGF‑beta signaling pathways that affect blood vessel growth and remodeling.

Also referred to as Winrevair.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study wants to find out if sotatercept can improve the lungs' ability to transfer oxygen during exercise in patients with pulmonary arterial hypertension.
Who it's for
Adults who have been diagnosed with pulmonary arterial hypertension.
What's involved
Participants will receive an injection of sotatercept about every three weeks, have regular clinic visits, physical exams, lung function and exercise tests, a heart ultrasound, and blood draws.
Time commitment
The trial lasts about 29 weeks and includes 18 clinic visits.
  • Phase 4: studies an already-approved treatment
  • Time commitment: about 2 weeks
