6. Able to fluently speak and read the local language.

7. Men or women aged 18-80; women of childbearing potential (as defined below) must:

   1. Have a negative serum pregnancy test at Screening and a negative urine pregnancy test at Baseline and agree to perform monthly serum pregnancy tests, and,

   2. Agree to use two reliable methods of contraception in parallel, from Screening Visit 1 until 1 month after study drug discontinuation (see details below).

      • A female is considered to have childbearing potential unless she meets at least one of the following criteria:

13. Initiation of diuretics within 1 week prior to the Baseline period.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Evaluation of the Reliability and the Construct Validity of the Cardiopulmonary Symptoms Domain of the PAH-SYMPACT	The Cardiopulmonary Symptoms domain consists of 6 items reported on a 5-point Likert scale (from 0 to 4). The value 0 means "no symptom" and value 4 corresponds to "very severe symptoms".The symptoms part of the PAH-SYMPACT was administered daily over a 7 day period. The recall period of symptom items is the last 24 hours. An average Cardiopulmonary Symptoms domain score is determined based on the daily scores of the 6 items. It was administered two times (daily during 7 days each time) prior to administration of Macitentan (Visit 2, Baseline) and daily during the 7-day period in the treatment period prior to Visit 3 (Week 8) and Visit 4 (Week 16).	From Screening Visit (Visit 1) to End of Treatment (EOT) Visit (Visit 4, Week 16)
Evaluation of the Reliability and the Construct Validity of the Cardiovascular Symptoms Domain of the PAH-SYMPACT	The Cardiovascular Symptoms domain consists of 5 items reported on a 5-point Likert scale (from 0 to 4). The value 0 corresponds to "no symptoms" and value 4 corresponds to "very severe symptoms". The symptoms part of the PAH-SYMPACT was administered daily over a 7 day period. The recall period of symptom items is the last 24 hours. An average Cardiovascular Symptoms domain score is determined based on the daily scores of the 5 items. It was administered two times (daily during 7 days each time) prior to administration of Macitentan (Visit 2, Baseline) and daily during the 7-day period in the treatment period prior to Visit 3 (Week 8) and Visit 4 (Week 16).	From Screening Visit (Visit 1) to End of Treatment (EOT) Visit (Visit 4, Week 16)
Evaluation of the Reliability and the Construct Validity of the Physical Impacts Domain of the PAH-SYMPACT	The Physical Impacts domain consists of 7 items reported on a 5-point Likert scale (from 0 to 4). The value 0 corresponds to "not at all"/"with no difficulty at all" and value 4 corresponds to "very much"/"extremely"/ "not able at all". The impacts part of the PAH-SYMACT was administered on Day 7 of the symptoms part administration. Items in the impact part have a 7 day recall period. An average Physical Impacts domain score is determined based on the 7 items in the domain. It was administered two times prior to administration of Macitentan (Visit 2, Baseline) and during the 7-day period in the treatment period prior to Visit 3 (Week 8) and Visit 4 (Week 16).	From Screening Visit (Visit 1) to End of Treatment (EOT) Visit (Visit 4, Week 16)
Evaluation of the Reliability and the Construct Validity of the Cognitive/Emotional Impacts Domain of the PAH-SYMPACT	The Cognitive/Emotional Impacts domain consists of 4 items reported on a 5-point Likert scale (from 0 to 4). The value 0 corresponds to "not at all"/"with no difficulty at all" and value 4 corresponds to "very much"/"extremely"/ "not able at all". The impacts part of the PAH-SYMACT was administered on Day 7 of the symptoms part administration. Items in the impact part have a 7 day recall period. An average Cognitive/Emotional Impacts domain score is determined based on the 4 items in the domain. It was administered two times prior to administration of Macitentan (Visit 2, Baseline) and during the 7-day period in the treatment period prior to Visit 3 (Week 8) and Visit 4 (Week 16)."
