Brief summary
The purpose of the study is to assess the effects of selexipag on right ventricular (RV) function in participants with Pulmonary arterial hypertension (PAH).
Interventions
Participants will receive tablets at a starting dose of 200 mcg on Day 1. Dose will be up-titrated from Day 1 to the end of Week 12 (Day 84) to determine individual maintenance dose (IMD). Then, participants will receive JNJ-67896049 tablets at their IMD from Week 13 to Week 52.

Number of Participants With Adverse Events (AEs) Leading to Premature Discontinuation of Study Drug
Number of participants with AEs leading to premature discontinuation of study drug were reported. An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.
Time frame: Day 1 up to last dose of study drug (up to Week 52)
Population: Safety analysis set included all participants who received at least 1 dose of study intervention.

Number of Participants With Adverse Events of Special Interest (AESI)
Number of participants with AESI were reported. An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. AESI were anaemia, bleeding events, gastrointestinal disturbances denoting intestinal intussusception (manifested as ileus or obstruction), hyperthyroidism, hypotension, light-dependent non-melanoma skin malignancies, major adverse cardiovascular events (MACE), medication errors, ophthalmological effects associated to retinal vascular system, pregnancy, pulmonary venoocclusive disease associated with pulmonary oedema, renal function impairment / acute renal failure.
Time frame: Day 1 up to 3 days after last dose of study drug (up to 52 weeks and 3 days that is 367 days)
Population: Safety analysis set included all participants who received at least 1 dose of study intervention.

Number of Participants With Change From Baseline to Week 26 in World Health Organization (WHO) Functional Class
WHO functional classification for PAH ranged from Class I (no limitation in physical activity, ordinary physical activity does not cause undue dyspnea or fatigue, chest pain or near syncope), Class II (slight limitation of physical activity, ordinary physical activity cause undue dyspnea or fatigue, chest pain or near syncope), Class III (marked limitation of physical activity, less than ordinary activity cause undue dyspnea or fatigue, chest pain or near syncope) and Class IV (cannot perform a physical activity without any symptoms, dyspnea and/or fatigue may even be present at rest). Change from baseline in WHO functional class was classified into Improved, No change and Worsened. Improvement =reduction in functional class; worsened =increase in functional class; and no change = no change in functional class.
Time frame: Baseline, Week 26
Population: Safety analysis set included all participants who received at least 1 dose of study intervention. Here, N (Overall number of participants analyzed) signifies participants evaluable for this outcome measure.

Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Serious adverse event (SAE) was any untoward medical occurrence that at any dose resulted in death, was life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was a suspected transmission of any infectious agent via a medicinal product. Any AE occurring at or after the initial administration of study intervention up to 3 days after last dose of study intervention was considered as treatment-emergent.
Time frame: Day 1 up to 3 days after last dose of study drug (up to 52 weeks and 3 days that is 367 days)
Population: Safety analysis set included all participants who received at least 1 dose of study intervention.
| Arm | Measure | Group | Value (COUNT_OF_PARTICIPANTS) |

| Selexipag | Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) | AEs | 9 Participants |
| Selexipag | Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) | SAEs | 1 Participants |
Number of Participants With Treatment-Emergent Marked Laboratory Abnormalities
Number of participants with treatment-emergent marked laboratory abnormalities in alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin, creatinine, sodium, potassium, hemoglobin, hematocrit; EVF; PCV (male), hematocrit; EVF; PCV (female), platelets (assuming no platelet cluster), leukocytes; white blood cells, Neutrophils (Abs), Eosinophils (Abs), lymphocytes (Abs) were reported. Abnormalities that occurred after study treatment start and up to 3 days after study treatment discontinuation, that were not present at baseline, were treatment-emergent. Treatment-emergent marked laboratory abnormalities were determined at the investigator's discretion.
Time frame: Day 1 up to 3 days after last dose of study drug (up to 52 weeks and 3 days that is 367 days)
Population: Safety analysis set included all participants who received at least 1 dose of study intervention.
