A Study of Sotatercept (MK-7962) in Japanese Children With Pulmonary Arterial Hypertension (PAH) (MK-7962-032)

7 de setembro de 2026 atualizado por: Merck Sharp & Dohme LLC

A Phase 2 Open-label Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Efficacy of Sotatercept (MK-7962) in Japanese Children From 1 to Less Than 18 Years of Age With PAH on Standard of Care.

The goal of this study is to learn about the safety of sotatercept and how well Japanese children tolerate it, when taken along with standard (usual) pulmonary arterial hypertension (PAH) treatment. Researchers also want to learn what happens to it in a person's body over time and whether it lowers resistance in blood vessels in the lungs.

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Experimental: Sotatercept
Participants receive sotatercept by subcutaneous injection every 3 weeks (Q3W) for up to approximately 24 weeks while continuing standard-of-care background therapy for PAH. Participants start at a dose of 0.3 mg/kg Q3W, and may titrate up to the target dose of 0.7 mg/kg SC injection Q3W starting at Week 6 based on protocol-defined dose-escalation guidance. After Week 24, participants who meet certain requirements may choose to continue receiving sotatercept for up to 58 months.
Biológico: Sotatercept
