Study Endpoints

Primary Endpoints

Area Under the Plasma Concentration-Time Curve From Time Zero to Last Sample Time (AUC0-tlast) of Xevinapant (Debio 1143)
Predose, 0.25, 0.5, 1.0, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24 , 36, 48 and 72 hours postdose

The area under the concentration-time curve (AUC) from time zero (= dosing time) to the last sampling time (tlast) at which the concentration is at or above the lower limit of quantification. Calculated using the mixed log-linear trapezoidal rule (linear up, log down).

Area Under the Plasma Concentration-Time Curve From Time Zero Extrapolated to Infinity (AUC0-inf) of Xevinapant (Debio 1143)
Predose, 0.25, 0.5, 1.0, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24 , 36, 48 and 72 hours postdose

The AUC from time zero (dosing time) extrapolated to infinity, based on the predicted value for the concentration at t last , as estimated using the linear regression from Terminal first order (elimination) rate constant (Lambda z) determination. AUC0-inf = AUC0-t plus Clast pred/lambda z. Lambda Z was terminal elimination rate constant determined from the terminal slope of the log-transformed plasma concentration curve using linear regression on terminal data points of the curve.

Maximum Observed Plasma Concentration (Cmax) of Xevinapant (Debio 1143)
Predose, 0.25, 0.5, 1.0, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24 , 36, 48 and 72 hours postdose

Cmax was obtained directly from concentration versus time curve.
