A Double-blind, Randomized, Placebo-controlled, Four-way Crossover Phase 1 Study Including an Open-label Positive Control (Moxifloxacin) to Assess the Effect of Repeated Daily Doses of 10 mg and 30 mg Macitentan on the QT/QTc Interval of the ECG in Healthy Male and Female Subjects

Brief Summary
The study is intended to demonstrate that macitentan does not have an effect on cardiac repolarization exceeding the threshold of regulatory concern after repeated administration of daily oral doses of 10 and 30 mg to healthy male and female subjects.

Outcome Measures
Primary Outcomes (1)
Baseline-adjusted placebo-corrected QT interval according to Fridericia's correction (QTcF)
The QTcF interval was obtained directly from the Holter ECG monitoring.Triplicate ECG recordings were obtained from a 12-lead Holter recording device at various time points on Day 8. Baseline data were obtained from the pre-dose recording on Day 1 (from about 45 to 15 minutes prior to the morning dose). The QTcF interval is the QT interval (interval from beginning of the Q wave until end of the T wave) corrected for heart rate with Fridericia's formula (QTcF = QT/RR\^0.33 where RR is 60/heart rate)
Day 8
Secondary Outcomes (15)
Placebo corrected change from baseline in heart rate on Day 8
Day 8
Placebo corrected change from baseline in RR interval (the interval from the onset of one QRS complex to the onset of the next QRS complex) on Day 8
Day 8
Placebo corrected change from baseline in PR interval (time interval from the beginning of the P wave to the beginning of the QRS complex) on Day 8
Day 8
Placebo corrected change from baseline in QRS interval (time interval from the beginning of the Q wave to the end of the S wave) on Day 8
