Clinical Study to Assess the Efficacy and Safety of Macitentan in Patients With Pulmonary Hypertension After Left Ventricular Assist Device Implantation
a study on High Blood Pressure
STUDY OBJECTIVES Primary objective 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.

Open to people ages 18 years and up
- Written Informed Consent prior to initiation of any study-mandated procedure.
- Males or females ≥ 18 years of age.
- Surgical implantation of LVAD within 90 days prior to Randomization.
- Hemodynamic evidence of PH on Baseline right heart catheterization (RHC) by the thermodilution method. Baseline RHC is defined as the last hemodynamic measurements after LVAD implantation and prior to the first dose of study treatment. PH is defined as:
- Mean pulmonary arterial pressure (mPAP) ≥ 25 mmHg and
- Pulmonary artery wedge pressure (PAWP) ≤ 18 mmHg and
- PVR > 3 Wood units.
- Stabilization of the patient for 48 h prior to the Baseline RHC, defined as:
- No LVAD pump speed/flow rate changes and
- Stable dose of oral diuretics and
- No intravenous (i.v.) inotropes or vasopressors and
- Patient able to ambulate.
- A woman of childbearing potential is eligible only if she has:
- A negative serum pregnancy test result during the Screening period (Visit 1) and Randomization (Visit 2) and
- Agreement to undertake monthly serum pregnancy tests during the study and up to 30 days after study treatment discontinuation and
- Agreement to use one of the methods of contraception / follow the contraception scheme described in Section 4.5 from Screening and up to at least 30 days after study treatment discontinuation.
- Patient must be randomized within 14 days of Baseline RHC.
