Demonstrating clinical benefits with peer reviewed research1-2

Ventavis is indicated for the treatment of adult patients with primary pulmonary hypertension (PH), classified as New York Heart Association (NYHA) functional class (FC) III, to improve exercise capacity and symptoms3


The efficacy and safety profile of Ventavis (iloprost trometamol) as a treatment for PH is supported by extensive clinical trial data and real-world evidence

Choose from the studies below to see a summary:

    AIR (Aerosolised Iloprost Randomised) is a key clinical study investigating the efficacy of Ventavis (iloprost trometamol) as a therapy for PH

    While continuous infusion of a prostacyclin analogue has been shown to reduce mortality in patients with severe PH, there are limitations associated with intravenous administration


    Designed to combine the beneficial effects of prostacyclin analogues with those of an inhalational application, aerosolised iloprost was developed as an alternative form of prostacyclin analogue therapy5,6

    Study design:

    Double-blind, randomised, placebo-controlled trial followed by an open-label extension


    Study period:

    12 weeks



    37 European centres



    203 patients with PH FC III/IV*


    This study contains an off-label patient population (NYHA FC IV, 41.4%, n=84)


    *According to the NYHA Classification system

    Ventavis is indicated for the treatment of adult patients with primary PH, classified as NYHA FC III, to improve exercise capacity and symptoms3

    The combined primary endpoint was met by 17% of patients treated with Ventavis compared with 5% of those receiving placebo (p=0.007)


    When assessed separately, the mean change from baseline after 12 weeks of treatment in the 6-minute walking distance was an increase of 22 meters in the Ventavis group compared to -3.3 meters in the placebo group3


    The NYHA FC was improved with Ventavis in 26% of patients (placebo: 15%) (p=0.032), unchanged in 67.7% of patients (placebo: 76%) and deteriorated in 6.3% of patients (placebo: 9%)


    Patients who improved by at least one NYHA functional class (secondary endpoint)

    The total number of adverse events did not differ significantly between the groups. The most common adverse events in the Ventavis group (n=101) were increased cough (38.6%), headache (29.7%) and flushing (26.7%)


    *p=0.032 for the comparison of rates of improvement with the placebo group




    Download Summary

    The clinical efficacy of Ventavis was demonstrated in this placebo-controlled trial, with further improvements in NYHA class compared with placebo observed during the open-label phase compared to the double-blind phase
