Inclusion/Exclusion Criteria (Data source: WHO)

Inclusion criteria:
1. Parent(s) (preferably both, if available, or as per local requirements, or their legally authorized representatives [LARs]) must sign an ICF indicating that he or she understands the purpose of, and procedures required for, the study and is willing to allow the child to participate in the study. Assent is also required of children capable of understanding the nature of the study (typically 7 years of age and older) as described in Informed Consent Process in Section 10.4, Regulatory, Ethical, and Study Oversight Considerations.
2. Male and female participants between =2 and <18 years of age weighing =9 kg at Randomization.
3. PAH diagnosis confirmed by documented historical RHC performed at any time before participant’s screening, and characterized by:
• mPAP =25 mmHg,
AND
• Pulmonary arterial wedge pressure (PAWP) =15 mmHg (in the absence of pulmonary vein obstruction and/or significant lung disease, PAWP can be replaced by left atrial pressure or, in absence of mitral stenosis, by left ventricular end diastolic pressure)
AND
• Indexed PVR index (PVRi) >3 Wood units × m2.
4. PAH (WHO Group 1), including patients with Down syndrome, of the following etiologies:
• Idiopathic PAH (IPAH).
• Heritable PAH (HPAH).
• PAH associated with congenital heart disease (PAH-aCHD):
– PAH with coincidental CHD (ie, a small atrial septal defect, ventricular septal defect, or patent ductus arteriosus that does not itself account for the development of elevated PVR) and if approved by the BCAC, see Section 10.4).
– Post-operative PAH (persisting / recurring/ developing =6 months after repair
of CHD).
• Drug or toxin-induced.
• PAH associated with HIV.
5. WHO FC II and III.
6. Participants treated with at least 1 PAH-specific treatment, eg, an ERA and/or a PDE-5 inhibitor/soluble guanylate cyclase stimulator, provided that the treatment dose(s) has been stable for at least 3 months prior to screening.
7. A female participant of childbearing potential (for a definition refer to section 10.6) is eligible only if the following apply:
? Has a negative highly sensitive serum pregnancy test (ß-human chorionic gonadotropin) at screening and a negative urine pregnancy test at randomization.
? Agrees to undertake monthly urine pregnancy tests during the study and up to at least 30 days after study treatment discontinuation.
? If sexually active, practicing a highly effective method of birth control consistent with local regulations regarding the use of birth control methods for subjects participating in clinical studies until 30 days after last dose of study intervention. Examples of acceptable methods of contraception are located in Section 10.6. It is the responsibility of the investigator to ensure appropriate counselling, including consultation with a specialist (if needed), to the subject and/or parent(s) / LAR(s) on the acceptable method of contraception. To ensure compliance, the study personnel must remind female participants of childbearing potential who are sexually active and their parent(s) / LAR(s) at each visit to use the methods of contraception defined for this study. These reminders must be documented in the source documents.
