Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Observed Plasma Analyte Concentration (Cmax) of Macitentan | Cmax is defined as maximum observed plasma analyte concentration of macitentan. | Predose up to 216 hours postdose (up to Day 10) | 
| Area Under the Plasma Analyte Concentration Versus Time Curve From Time Zero To Time of the Last Quantifiable (Non-below Quantification Limit [Non-BQL]) Concentration (AUC [0-last]) of Macitentan | AUC (0-last) is defined as area under the plasma analyte concentration versus time curve from time 0 to time of the last quantifiable (non-BQL) concentration of macitentan. | Predose up to 216 hours postdose (up to Day 10) | 
| Area Under the Plasma Analyte Concentration-time Curve From Time Zero to Infinite Time (AUC[0-infinity]) of Macitentan | AUC (0-infinity) is defined as the area under the plasma analyte concentration-time curve from time 0 to infinite time of macitentan, calculated as the summation of AUC(0-last) and C(last)/lambda(z); where AUC(0-last) is area under the analyte concentration-time curve from time zero to last quantifiable time, Clast is the last observed measurable (non-BQL) plasma analyte concentration, and lambda(z) is apparent terminal elimination rate constant. | Predose up to 216 hours postdose (up to Day 10) |
