Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area Under the Curve From Time Zero to Extrapolated Infinite Time (AUC Infinity) | AUCinf = Area under the plasma concentration-time curve from time 0 (predose) extrapolated to infinite time; measured in nanograms times hour per milliliter (ng•hr/mL). | 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose | 
| Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) | AUClast = area under the plasma concentration-time curve from 0 (predose) to the time of the last measureable concentration (Clast); measured in nanograms times hour per milliliter (ng•hr/mL). | 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose | 
| Maximum Observed Plasma Concentration (Cmax) | Cmax = maximum observed plasma concentration. Measured in nanograms per milliter (ng/mL). | 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to Reach Maximum Plasma Concentration (Tmax) | Tmax = time (hours) to maximum plasma concentration (Cmax). | 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose | 
| Plasma Elimination Half-life (t1/2) | t1/2 = terminal elimination half-life in hours. | 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 10, 12, 24, 36, 48, 72 hours post dose |
