Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The AC-055B201/MUSIC study is a Phase II study, comparing one dose of ACT-064922 (macitentan) 10 mg with placebo in patients with idiopathic pulmonary fibrosis (IPF). The main study objective is to demonstrate that macitentan positively affects the forced vital capacity (FVC) in comparison with placebo in patients with idiopathic pulmonary fibrosis (IPF). The secondary objectives are to evaluate the effect of macitentan on the time to disease worsening or death in patients with IPF, and to evaluate the benefit/risk profile of macitentan in the treatment of patients with IPF.
