This clinical trial is focused on studying Pulmonary Arterial Hypertension (PAH), a condition where the blood pressure in the arteries of the lungs is higher than normal. The study will use a treatment called sotatercept, which is administered as a solution for injection. Sotatercept is being tested to see how safe and tolerable it is for people with PAH when given in doses based on their weight.
The purpose of the study is to evaluate the long-term safety and tolerability of sotatercept. Participants will receive sotatercept through injections under the skin. The study will monitor participants over a period to observe any side effects or adverse events that may occur. The study aims to ensure that sotatercept can be safely used by people with PAH as part of their standard care.
Participants in this study will have completed a previous study involving sotatercept and will not have started treatment with commercially available sotatercept. The study will track the number of participants who experience adverse events and those who discontinue the study due to these events. This information will help determine the safety of sotatercept for long-term use in managing PAH.
