Study Endpoints
Primary Endpoints
Maximum Observed Analyte Concentration (Cmax) of Selexipag and ACT-333679
Predose and 0 to 72 hours postdose

The Cmax is the maximum observed analyte concentration.

Area Under Analyte Concentration From Time Zero to the Last Quantifiable Concentration (AUC [0-last]) of Selexipag and ACT-333679
Predose and 0 to 72 hours postdose

AUC (0-last) defined as the area under the analyte concentration-time curve from time zero to time of the last measurable (non-BQL) analyte concentration, calculated by linear-linear trapezoidal summation.

Plasma analyte concentration 24 hours (C24) Post Dose of Selexipag and ACT-333679
Predose and 0 to 72 hours postdose

C24 defined as plasma analyte concentration at 24 hours postdose.

Area Under the Analyte Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-infinity])
Predose and 0 to 72 hours postdose

AUC (0-infinity) is defined the area under the analyte concentration-time curve from time zero to infinity time, calculated as the sum of AUC (0-last) and C(last)/lambda(z); wherein AUC (0-last) is area under the plasma concentration-time curve from time zero to last measurable concentration, C(last) is the last observed measurable concentration, and lambda(z) is apparent terminal elimination rate constant.

Cohort 1: Selexipag Matrix TabletsEXPERIMENTALParticipants will receive oral doses of selexipag matrix tablets based on release profiles (IR=immediate release, F=fast release, M=medium release and S=slow release) in treatment sequence 1 (IR+F+M+S), treatment sequence 2 (F+S+IR+M), treatment sequence 3 (M+ IR+ S+F) and treatment sequence 4 (S+M+F+IR) in periods 1, 2, 3, and 4, respectively under fasted condition. A washout period of at least 7 days will be maintained between each treatment period.
Cohort 2: Selexipag Encapsulated PelletsEXPERIMENTALParticipants will receive oral doses of selexipag encapsulated) pellets based on release profiles (IR=immediate release, F=fast release, M=medium release and S=slow release) in treatment sequence 1 (IR+F+M+S), treatment sequence 2 (F+S+IR+M), treatment sequence 3 (M+ IR+ S+F) and treatment sequence 4 (S+M+F+IR) in periods 1, 2, 3, and 4, respectively under fasted condition. A washout period of at least 7 days will be maintained between each treatment period.
