What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants With Adverse Events (AEs)
Time Frame: Baseline (Double-Blind Period) up to Week 243 (End of Open-Label Period)
A summary of serious and all other non-serious AEs, which include adverse events reported for laboratory tests and vital signs, is located in the Reported Adverse Event module.
Baseline (Double-Blind Period) up to Week 243 (End of Open-Label Period)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
6-Minute Walk Distance (6MWD) at Baseline and Weeks 16, 28, 40 and 52
Time Frame: Baseline and Weeks 16, 28, 40 and 52
6MWD measured the distance a participant was able to walk unassisted in 6 minutes.
Baseline and Weeks 16, 28, 40 and 52
Borg Dyspnea Assessment at Baseline and Weeks 16, 28, 40 and 52
Time Frame: Baseline and Weeks 16, 28, 40 and 52
Borg dyspnea score is a participant rated measure of their greatest degree of shortness of breath during exertion (6-minute walk test). Score ranged from 0 (nothing at all) to 10 (very, very severe [maximal]).
Baseline and Weeks 16, 28, 40 and 52
Probability of No Pulmonary Arterial Hypertension (PAH) Deterioration at Weeks 16, 28, 40 and up to 52
Time Frame: Baseline and Weeks 16, 28, 40 and 52
World Health Organization Functional Classification Assessment (WHO FC) is a method of classifying disease severity in PAH. The classes are: Class I: pulmonary hypertension (PH) but without resulting limitation of physical activity, Class II: PH resulting in slight limitation of physical activity, Class III: PH resulting in marked limitation of physical activity, Class IV: PH with inability to carry out any physical activity without symptoms. Deterioration of WHO FC is defined as moving to a higher WHO FC within one visit. Results are presented as Kaplan-Meier estimates (% probability) of remaining free from WHO FC deterioration after a given time.
Baseline and Weeks 16, 28, 40 and 52
