SECONDARY outcome

Timeframe: Up to 22 days (last participant discontinuation)

Population: The efficacy analysis set was defined as all subjects who receive at least one dose of study drug during this extension study and have efficacy observations at baseline of the preceding study (B1321052) in any efficacy assessments. Descriptive statistics for any efficacy endpoints were not calculated due to a small number of participants.

Clinical worsening is defined as 1) Hospitalization for worsening pulmonary arterial hypertension, 2) On-study death, 3) Heart-lung or lung transplantation, 4) Atrial septostomy, 5) Addition of the chronic medications for the treatment of worsening pulmonary arterial hypertension, and 6) Initiation of oxygen.

SECONDARY outcome

Timeframe: Up to 22 days (last participant discontinuation)

Population: The efficacy analysis set was defined as all subjects who receive at least one dose of study drug during this extension study and have efficacy observations at baseline of the preceding study (B1321052) in any efficacy assessments. Descriptive statistics for any efficacy endpoints were not calculated due to a small number of participants.

Change from baseline in 6-minute walk distance is calculated as the value at each time point (every 12 weeks until Week 48 and every 24 weeks after Week 48) minus value at baseline.

Timeframe: Up to 22 days (last participant discontinuation)

Population: The efficacy analysis set was defined as all subjects who receive at least one dose of study drug during this extension study and have efficacy observations at baseline of the preceding study (B1321052) in any efficacy assessments. Descriptive statistics for any efficacy endpoints were not calculated due to a small number of participants.

The change from baseline in WHO functional class was classified into "Improved", "No change" and "Worsened". The change from baseline in WHO functional class is summarised with percentage of participants at each time point (every 12 weeks until Week 48 and every 24 weeks after Week 48).
