A Study of Fixed Dose Combination of Macitentan/Tadalafil (10 mg/20 mg) Compared to the Reference Free Combination of Macitentan and Tadalafil in Healthy Adult Participants
brief summary
The purpose of this study is to demonstrate bioequivalence on the primary pharmacokinetic (PK) parameters between macitentan and tadalafil administered as a fixed dose combination (FDC) (test) of macitentan/tadalafil and the co- administered free combination (reference) of macitentan (Opsumit) and tadalafil (Adcirca) in fasted conditions in healthy adult participants; and to evaluate the effect of food on the primary PK parameters of macitentan and tadalafil administered as an FDC of macitentan/tadalafil in fed versus fasted conditions in healthy adult participants.
