Effects of Ventavis in Patients With Pulmonary Hypertension (PH) Secondary to Chronic Obstructive Pulmonary Disease (COPD)

Phase 2

Terminated

• Conditions: Pulmonary Hypertension; Chronic Obstructive Pulmonary Disease
• Interventions: Drug: Placebo; Drug: Iloprost

• Registration Number: NCT01437878
• Lead Sponsor: Actelion

Brief Summary

This is a phase 2, Multi-center, double-blind, randomized, placebo-controlled study to evaluate the effects of inhaled Iloprost in patients with pulmonary hypertension secondary to COPD. The main objective is to investigate the effect of iloprost on exercise endurance time during constant work rate cardiopulmonary exercise testing. Other efficacy and safety endpoints will additionally be analyzed.

Change in Systolic Pulmonary Arterial Pressure	15 minutes	On Day 1 patients underwent acute hemodynamic testing prior to and immediately after (no more than 15 minutes) the first dose of inhaled iloprost or placebo. All hemodynamic variables were measured using a Swan-Ganz catheter.
Change in Mean Right Atrial Pressure	15 minutes	On Day 1 patients underwent acute hemodynamic testing prior to and immediately after (no more than 15 minutes) the first dose of inhaled iloprost or placebo. All hemodynamic variables were measured using a Swan-Ganz catheter.
Change in Right Ventricular Pressure	15 minutes	On Day 1 patients underwent acute hemodynamic testing prior to and immediately after (no more than 15 minutes) the first dose of inhaled iloprost or placebo. All hemodynamic variables were measured using a Swan-Ganz catheter.
Change in Pulmonary Vascular Resistance	15 minutes	On Day 1 patients underwent acute hemodynamic testing prior to and immediately after (no more than 15 minutes) the first dose of inhaled iloprost or placebo. All hemodynamic variables were measured using a Swan-Ganz catheter.
Change in Diastolic Pulmonary Arterial Pressure	15 minutes	On Day 1 patients underwent acute hemodynamic testing prior to and immediately after (no more than 15 minutes) the first dose of inhaled iloprost or placebo. All hemodynamic variables were measured using a Swan-Ganz catheter.
Change in End Tidal Partial Pressure of Carbon Dioxide	Baseline to week 4	Change from baseline to week 4. Pulmonary gas exchange was measured during incremental and constant work rate exercise testing.
Change in Oxygen Uptake	Baseline to week 4	Change from baseline to week 4. Pulmonary gas exchange was measured during incremental and constant work rate exercise testing.
Change in Carbon Dioxide Output	Baseline to week 4	Change from baseline to week 4. Pulmonary gas exchange was measured during incremental and constant work rate exercise testing.
Change in Arterial Oxygen Saturation as Indicated by Pulse Oximetry	Baseline to week 4	Change from baseline to week 4. Arterial oxygen was determined by pulse oximetry during incremental and constant work rate exercise testing.
Change in Tidal Volume	Baseline to week 4	Change from baseline to week 4. Tidal volume was measured during incremental and constant work rate exercise testing.
Participants With Treatment-emergent Adverse Events	Baseline up to 24 hours post-EOT, approximately 4 weeks	Treatment-emergent adverse events up to 24 hours post-end of treatment (EOT), approximately 4 weeks
Change in Mean Pulmonary Arterial Pressure	15 minutes	On Day 1 patients underwent acute hemodynamic testing prior to and immediately after (no more than 15 minutes) the first dose of inhaled iloprost or placebo. All hemodynamic variables were measured using a Swan-Ganz catheter.
