What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area Under Concentration from time zero to the last quantifiable (AUC [0-last]) | Area under the concentration-time curve (AUC) from time 0 to the time of the last measurable (non-below quantification limit [non-BQL]) concentration, calculated by linear-linear trapezoidal summation. | Predose up to Day 3 | 
| 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. | Predose up to Day 3 | 
| Maximum Observed Analyte Concentration (Cmax) | Maximum observed analyte concentration will be assessed. | Predose up to Day 3 | 
| Time to Reach Maximum Concentration (Tmax) | Tmax is defined as actual sampling time to reach maximum observed analyte concentration will be assessed. | Predose up to Day 3 | 
| Apparent Terminal Elimination Halflife (t1/2term) | The elimination halflife (t1/2) is the time measured for the plasma concentration to decrease by 1 half to its original concentration. It is associated with the terminal slope of the semi logarithmic drug concentration time curve and calculated as 0.693/apparent terminal elimination rate constant (λz). | Predose up to Day 3 | 
| Apparent Terminal Elimination Rate Constant (lambda z) | Apparent terminal elimination rate constant, estimated by linear regression using the terminal loglinear phase of the log transformed concentration versus time data. | Predose up to Day 3 |
