NCT00617305
To evaluate the change from baseline in pulmonary vascular resistance (PVR), and other hemodynamic parameters, following the addition of ambrisentan to background phosphodiesterase type-5 inhibitor (PDE-5i) therapy in subjects with pulmonary arterial hypertension (PAH) who have demonstrated a sub-optimal response to PDE-5i monotherapy. The study was originally designed as a 2-arm, double-blind, randomized study in which patients received ambrisentan or placebo for 24 weeks, and then received ambrisentan blinded to dose for 24 weeks. With Protocol Amendment 2 (12 June, 2009), the study was switched to single-arm, open-label treatment, and all patients remaining in the placebo arm were switched to open-label ambrisentan treatment. Patients who enrolled after Amendment 2 all received open-label ambrisentan.
