Outcome Measures
Primary Outcomes (17)
Plasma PK of AJ201
AUC0-24hr: Area under the concentration-time curve from zero to 24 hours under fasting and fed conditions
Pre-dose to Day 6
Plasma PK of AJ201
AUC0-last: Area under the concentration-time curve from zero to the last observed concentration under fasting and fed conditions
Pre-dose to Day 6
Plasma PK of AJ201
AUC0-inf: Area under the concentration-time curve from time zero to infinity (extrapolated) under fasting and fed conditions
Pre-dose to Day 6
Plasma PK of AJ201
Cmax: Maximal observed concentration under fasting and fed conditions
Pre-dose to Day 6
Plasma PK of AJ201
Tmax: Time when the maximal concentration is observed under fasting and fed conditions
Pre-dose to Day 6
Plasma PK of AJ201
Residual area: Percentage of AUC0-inf due to extrapolation from the time of the last observed concentration to infinity, calculated as \[1 - (AUC0-last/AUC0-inf)\] x 100 under fasting and fed conditions
Pre-dose to Day 6
Plasma PK of AJ201
Tlag: Time of observation prior to the first observation with a measurable (non-zero) concentration under fasting and fed conditions
Pre-dose to Day 6
Plasma PK of AJ201
T½ el: Terminal elimination half-life under fasting and fed conditions
Pre-dose to Day 6
Plasma PK of AJ201
Kel: Terminal elimination rate constant under fasting and fed conditions
Pre-dose to Day 6
Plasma PK of AJ201
Cl/F: Apparent clearance under fasting and fed conditions
Pre-dose to Day 6
Plasma PK of AJ201
Vz/F: Apparent volume of distribution under fasting and fed conditions
Pre-dose to Day 6
Urine PK of AJ201
Ae0-24hr: Cumulative urinary excretion from time zero to 24 hours, calculated as the sum of the amounts excreted over each collection interval under fasting and fed conditions
Pre-dose to Day 7
Urine PK of AJ201
Ae0-48hr: Cumulative urinary excretion from time zero to 48 hours, calculated as the sum of the amounts excreted over each collection interval under fasting and fed conditions
Pre-dose to Day 7
Urine PK of AJ201
Ae0-last: Cumulative urinary excretion from time zero to the last observed concentrations, calculated as the sum of the amounts excreted over each collection interval under fasting and fed conditions
Pre-dose to Day 7
Urine PK of AJ201
Rmax: Maximal rate of urinary excretion, calculated by dividing the amount of drug excreted in each collection interval by the time over which it was collected under fasting and fed conditions
Pre-dose to Day 7
Urine PK of AJ201
TRmax: Time of maximal urinary excretion, calculated as the midpoint of the collection interval during which Rmax occurred under fasting and fed conditions
Pre-dose to Day 7
Urine PK of AJ201
ClR: Renal clearance, calculated as Ae0-24hr /AUC0-24hr under fasting and fed conditions
Pre-dose to Day 7
