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

9 giugno 2026 aggiornato da: 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.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: 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.

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Variazione media rispetto al basale del peptide natriuretico di tipo B del proormone N-terminale (NT-proBNP)
Lasso di tempo: Basale e settimana 24
Verrà riportata la variazione rispetto al basale nei livelli plasmatici di NT-proBNP.

Percentuale di partecipanti che hanno migliorato o mantenuto la propria classe funzionale dell'Organizzazione mondiale della sanità (WHO FC)
Lasso di tempo: Basale e settimana 24
La gravità dei sintomi della PAH di un individuo sarà classificata utilizzando il sistema FC dell'OMS. La classificazione funzionale dell'OMS per la PAH va dalla Classe I (nessuna limitazione nell'attività fisica, nessuna dispnea con attività normale), Classe II (lieve limitazione dell'attività fisica), Classe III (marcata limitazione dell'attività fisica) e Classe IV (impossibilità di eseguire un'attività fisica attività senza alcun sintomo, dispnea a riposo). Il cambiamento rispetto al basale in WHO FC sarà classificato in "Migliorato", "Nessun cambiamento" e "Peggiorato". Miglioramento = riduzione della FC, peggioramento = aumento della FC e nessun cambiamento = nessun cambiamento della FC.
