Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Selexipag
Treatment: Drugs - Placebo

Experimental: Selexipag - Participants will receive selexipag based on the body weight on Day 1 and will continue thereafter with twice daily dosing. Selexipag will be uptitrated during the first 12 weeks until the participants reaches the individual maximum tolerated dose (iMTD) or until a maximum dose corresponding to their baseline body-weight category is achieved. Uptitration is followed by a maintenance period after Week 12 until end of treatment (EOT), at the maximum tolerated dose.

Placebo Comparator: Placebo - Participants will receive matching placebo based on the body weight on Day 1 and will continue thereafter with twice daily dosing.


Treatment: Drugs: Selexipag
Selexipag tablet will be administered orally.

Treatment: Drugs: Placebo
Matching placebo tablets will be administered orally.
