Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Area Under Curve From 0 to tz (AUC0-tz)

AUC0-tz represents the area under the concentration curve of the analyte in plasma from 0 to the time of the last quantifiable plasma contentration of the analyte.
0, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 24, 36, 48, 72, 96, 120 hours post
Maximum Concentration (Cmax)
Time Frame: 0, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 24, 36, 48, 72, 96, 120 hours post
Cmax represents the maximum concentration of the analyte in plasma.
0, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 24, 36, 48, 72, 96, 120 hours post
Area Under Curve From 0 to ∞ Hours (AUC0-∞)
Time Frame: 0, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 24, 36, 48, 72, 96, 120 hours post
AUC0-∞ represents the area under the concentration curve of the analyte in plasma from 0 extrapolated to infinity.
0, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 24, 36, 48, 72, 96, 120 hours post
