Safety and Efficacy of Inhaled Treprostinil in Adult PH With ILD Including CPFE

Summary

This was a multicenter, randomized (1:1 inhaled treprostinil: placebo), double-blinded, placebo-controlled trial to evaluate the safety and efficacy of inhaled treprostinil in subjects with pre-capillary pulmonary hypertension (PH) associated with interstitial lung disease (ILD) including combined pulmonary fibrosis and emphysema (CPFE). The study included 326 patients at approximately 120 clinical trial centers. The treatment phase of the study lasted approximately 16 weeks. Patients who completed all required assessments were eligible to enter an open-label, extension study (RIN-PH-202).
