Is this trial a fit for you?

Likely a good fit

Ideal candidates are people with pulmonary arterial hypertension who completed a prior sotatercept parent study without early discontinuation and can attend scheduled follow-up visits.

Probably not a fit

People who did not participate in a sotatercept parent study, who had serious sotatercept-related adverse events, missed more than four consecutive doses before entry, or who are pregnant or breastfeeding are unlikely to benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This long-term follow-up enrolls people who completed prior sotatercept PAH trials to continue receiving sotatercept alongside their standard PAH medicines. Participants will attend regular clinic visits for monitoring of adverse events, laboratory tests, and overall tolerability over an extended period. The primary aim is to collect long-term safety and tolerability data rather than to compare efficacy against a control. Enrollment is restricted to those who did not discontinue their parent study and who meet routine eligibility checks such as pregnancy status and recent dosing history.

Why it matters

Potential benefit: If successful, the study could confirm that sotatercept is safe and tolerable when taken long-term with standard PAH treatments, supporting its use as a durable therapy option.

How similar studies have gone: Earlier clinical trials of sotatercept in PAH reported promising clinical effects, but long-term safety and tolerability data are still being gathered.
