Study Endpoints
Primary Endpoints
Area under the plasma concentration-time curve (AUC) from time zero to time t of the last measured concentration above the limit of quantification (AUC0-t)
Up to 36 hours after treatment administration

The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles

AUC from zero to infinity (AUC0-inf)
Up to 36 hours after treatment administration

The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles

The maximum plasma concentration (Cmax)
Up to 36 hours after treatment administration

The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles

The time to reach Cmax (tmax)
Up to 36 hours after treatment administration

The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles

Terminal half-life (t½)
Up to 36 hours after treatment administration

The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles
