Experimental: Selexipag 200 micro gram (μg)
Study intervention will be up-titrated to allow each participant to reach their individual maximum tolerated dose (iMTD), in the range of 200 μg to1600 μg (ie, 1 to 8 tablets) twice daily/once daily. Dosing frequency will be twice daily, except for participants with moderate hepatic impairment (Child-Pugh Class B) or who are concomitantly taking (a) moderate CYP2C8 inhibitor(s), who receive study intervention once daily. The dose will be up-titrated by the investigator/delegate in 200 μg twice daily/once daily increments at weekly intervals during scheduled TCs until reaching the iMTD. If the dose regimen is not well tolerated or symptoms cannot be fully managed with symptomatic treatment, the duration of the titration step can be prolonged to 2 weeks. If needed, the dose can be reduced by 200 μg twice daily/once daily.
Oral tablets containing 200 µg of selexipag. Depending on the iMTD, participants will receive 1 (200 µg) to 8 (1600 µg) tablets at each administration
Other Name: JNJ-678896049; ACT-293987
Placebo Comparator: Placebo
The comparator will be administered similarly to the experimental intervention.
Oral tablets without active compound. Participants can receive 1 to 8 tablets at each administration.
- Pulmonary Vascular Resistance (PVR) on Study Intervention up to Week 26 [ Time Frame: Up to week 26, within 2-5 hours post-dose ]PVR is measured by right heart catheterization (RHC) and expressed as percent of baseline value.
