A Clinical Study of Sotatercept (MK-7962) in People With Pulmonary Arterial Hypertension (PAH) (MK-7962-024)

Phase 2
Active, not recruiting
Conditions
Pulmonary Arterial Hypertension
Interventions
Registration Number
NCT06664801
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

Researchers are looking for other ways to treat people with PAH. In PAH, the blood vessels in the lungs become thick and narrow, which makes it harder for blood to flow to the lungs.

The goal of the study is to learn:

* What happens to different doses of sotatercept in a person's body over time when it is given using weight-banded doses compared to weight-based doses. There may be differences in how the medicine works with the new dosing method (weight-banded dosing) being studied in this trial.

* About the safety of sotatercept and if people tolerate it

Weight-based sotatercept dosingSotaterceptParticipants will receive sotatercept via subcutaneous (SC) injection every 3 weeks at an initial dose of 0.3 mg/kg and then at a maintenance dose of 0.7 mg/kg using a weight-based method during a 24-week treatment period. Participants will continue to take their background PAH therapy during the study.

Weight-banded sotatercept dosingSotaterceptParticipants will receive sotatercept via SC injection every 3 weeks at an initial dose of up to 45 mg and then at a maintenance dose of up to 90 mg using a weight-banded method during a 24-week treatment period.
