Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the efficacy of bosentan in treatment of patients with pulmonary hypertension and fibrosing lung disease. The primary endpoints is a fall from baseline pulmonary vascular resistance (PVR) to week 16 of 20%. ; Secondary Objective: To assess whether bosentan improves exercise capacity, and pulmonary blood flow in patients with pulmonary hypertension and fibrosing lung disease. The secondary endpoints are changes from baseline to week 16 in the following: 1. right heart catherisation (RHC) parameters: mean pulmonary arterial pressure, right atrial pressure, cardiac index, systemic vascular resistance. 2. Exercise capacity as measured by the 6-minute walk test, and Borg dyspnoea scale 3. Quality of life as measured by the CAMPHOR questionaire 4. Pulmonary blood flow 5. Lung function (DLco% predicted, FVC% predicted, Composite physiological index) 6. WHO functional class 7. Right ventricular mass (cardiac MRI) 8. Brain natriuretic peptide ; Primary end point(s): The primary end point is - Fall from baseline PVR (to week 16) of 20%.
