| Secondary Objective: NA;Timepoint(s) of evaluation of this end point: Over Period 1, Period 2 and Period 3 combined;Main Objective: The primary objective of this study is to assess whether temporary switching from a stable oral dose of selexipag to an intravenous (i.v.) dose of selexipag providing comparable exposure to active metabolite ACT-333679 and switching back to the initial oral dose of selexipag is safe and well tolerated in subjects with stable pulmonary arterial hypertension (PAH).; Primary end point(s): Main safety variables are: - Proportion of discontinuations due to prostacyclin-associated adverse events (AEs) - Proportion of AEs and serious AEs - Proportion of prostacyclin-associated AEs - Proportion of AEs related to injection site reactions - Proportion of PAH-related AEs | — |
