What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximum Observed Plasma Concentration (Cmax)	Maximum observed plasma concentration (Cmax) will be assessed.	Predose, Up to Day 57
Time to Reach Maximum Observed Plasma Concentration (Tmax)	Actual sampling time to reach maximum observed analyte concentration (Tmax) will be assessed.	Predose, Up to Day 57
Area Under Concentration from time zero to the last quantifiable AUC (0-last)	AUC from time zero to the last quantifiable concentration will be assessed.	Predose, Up to Day 57
Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-infinity])	The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC (0-last) and C (0-last)/lambda(z); wherein AUC (0-last) is area under the plasma concentration-time curve from time zero to last quantifiable time, C(last) is the last observed quantifiable concentration, and lambda (z) is elimination rate constant. AUC (0-infinity) will be assessed.	Predose, Up to Day 57
Time to Last Quantifiable Plasma Concentration (Tlast)	The Tlast, time to last observed quantifiable plasma concentration will be assessed.	Predose, Up to Day 57
Percentage of Area Under the Plasma Concentration-Time Curve Extrapolated From Last Measurable Concentration to Infinite Time (%AUC,ext)	Percentage of area under the plasma concentration-time curve extrapolated from last measurable concentration to infinite time (%AUC,ext) is calculated as (AUC [0-infinity] minus AUC [0-last])/ AUC [0-infinity])*100.	Predose, Up to Day 57
Apparent Clearance (CL/F)	Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood. CL/F will be calculated as CL/F = Dose/AUC [0-infinity]	Predose, Up to Day 57
Apparent Terminal Elimination Half-life (t1/2term)	Apparent terminal elimination half-life, calculated as 0.693/apparent terminal elimination rate constant (λz)	Predose, Up to Day 57
Apparent Terminal Elimination Rate Constant (lambda z)	Apparent terminal elimination rate constant, estimated by linear regression using the terminal log-linear phase of the log transformed concentration vs time data	Predose, Up to Day 57
Apparent Volume of Distribution (Vd/F)	Apparent volume of distribution based on the terminal phase following oral administration calculated as Vd/F = Dose/ apparent terminal elimination rate constant (λz)*AUC [0-infinity]	Predose, Up to Day 57
Metabolite to Parent Drug Ratio for Maximum Observed Plasma Concentration (MPR Cmax)	Metabolite to parent drug ratio for Cmax will be assessed.	Predose, Up to Day 57
Metabolite to Parent Drug Ratio for Area Under Concentration from time zero to the last quantifiable concentration (MPR AUC [0-last])	Metabolite to parent drug ratio for AUC [0-last] will be assessed.	Predose, Up to Day 57
Metabolite to Parent Drug Ratio for Area Under Curve from time zero extrapolated to infinity (MPR AUC [0-infinity])	Metabolite to parent drug ratio for AUC [0-infinity] will be assessed.	Predose, Up to Day 57
Area Under Curve from time of administration to 24 hours post dosing	AUC from time of administration to 24 hours post dosing will be assessed.	Predose, Up to Day 57
Area Under Curve from time of administration to 168 hours post dosing	AUC from time of administration to 168 hours post dosing will be assessed.	Predose, Up to Day 57

Secondary Outcome Measures

Outcome Measure	Time Frame
