STUDY OBJECTIVES Primary objective(s) To evaluate the effect of macitentan 10 mg on pulmonary vascular resistance (PVR) as compared to placebo in subjects with pulmonary hypertension (PH) after left ventricular assist device (LVAD) implantation.
Secondary objectives To evaluate the effect of macitentan 10 mg as compared to placebo on cardio-pulmonary hemodynamics and disease severity in subjects with PH after LVAD implantation.
To evaluate the safety and tolerability of macitentan 10 mg in subjects with PH after LVAD implantation.
Exploratory objectives To explore the potential effect of macitentan 10 mg as compared to placebo on right ventricular function in subjects with PH after LVAD implantation.
To explore the potential effect of macitentan 10 mg as compared to placebo on selected clinical events in subjects with PH after LVAD implantation.
To explore the potential effect of macitentan 10 mg as compared to placebo on renal function as measured by glomerular filtration rate (GFR) in subjects with PH after LVAD implantation.
