NCT07218029 — A Clinical Study of Sotatercept (MK-7962) in People With Pulmonary Arterial Hypertension (MK-7962-038)

Researchers are looking for more ways to treat PAH. In PAH, the blood vessels in the lungs become thick and narrow, which makes it harder for blood to flow. This causes high blood pressure in the lungs and overworks the heart. PAH can make it hard to breathe and be active. Some standard (usual) treatments for PAH can treat symptoms of PAH but do not stop PAH from getting worse.

Sotatercept is …
