Condition(s) targeted: Pulmonary Arterial Hypertension

Intervention: iloprost (5 µg) (Drug); placebo (Drug)

Phase: Phase 3

Status: Completed

Patients with symptomatic idiopathic pulmonary arterial hypertension (IPAH), or familial pulmonary arterial hypertension (FPAH) or pulmonary hypertension associated with Human immunodeficiency virus (HIV) or drugs/toxins in New York Heart Association (NYHA) functional class II to IV at baseline, naive to PAH treatment or currently being treated with a stable dose of either bosentan, ambrisentan or sildenafil will be enrolled in the PROWESS 15 study. This randomized, double blind, placebo-controlled, crossover, and single-dose study will determine whether a single inhaled dose of iloprost using the power 15 disc improves exercise capacity compared to placebo in patients with pulmonary arterial hypertension (PAH).

Primary outcome: 6-minute-walk Distance (6MWD)

Secondary outcome: Borg Dyspnea Score
