Brief Summary Selexipag is available in many countries for the treatment of pulmonary arterial hypertension (PAH). Due to the similarities between PAH and chronic thromboembolic pulmonary hypertension (CTEPH) and the observed efficacy of other PAH medicines in CTEPH, it is believed that selexipag could benefit to patients with CTEPH. This study aims to assess the efficacy and safety of selexipag in participants with inoperable or persistent/recurrent CTEPH. Detailed Description Participants will be recruited in two sequential cohorts: approximately the first 90 randomized participants will undergo a right heart catheterization (RHC) (and left heart catheterization LHC, if needed) with measurement of pulmonary vascular resistance (PVR) at Week 20 and will constitute the hemodynamic cohort; the remaining participants will constitute the non-hemodynamic cohort; who do not require a post-baseline hemodynamic assessment. They will undergo the same overall study assessments as the hemodynamic cohort excepted for RHC at Week 20.
