NCT00709956

Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • 6-minute-walk Distance (6MWD)

    The 6-minute walk test was performed 20-40 minutes after treatment. This was a non-encouraged test (the person conducting the test did not encourage the patient to walk farther or faster) that measured the distance covered over a 6-minute walk. It was conducted by a trained member of the site staff who was listed on the site's delegation of authority sheet. For patients who had never performed a 6-minute walk test previously, a training test was requested before the qualifying tests for randomization.
