Outcome Measures
Primary Outcome Measures
- Maximum Observed Plasma Concentration [Cmax] of Besifovir [Up to 24 Hours after study drug administration]
The Cmax is the maximum observed plasma concentration.
- Area Under the Curve [AUC] of of Besifovir [Up to 24 Hours after study drug administration]
Area under the plasma concentration versus time curve for Besifovir
Secondary Outcome Measures
- Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC[0-infinity]) of Besifovir [Up to 24 Hours after study drug administration]
Area under the plasma concentration-time curve from time zero to infinite time
- Time to reach the Cmax [Tmax] of Besifovir [Up to 24 Hours after study drug administration]
Time to reach the Cmax of Besifovir
- Apparent terminal half-life [t1/2] [Up to 24 Hours after study drug administration]
apparent terminal half-life of Besifovir
Other Outcome Measures
- Safety of Besifovir: incidence of treatment emergent adverse event [TEAE]'s, abnormalities [Up to 14 days after last study drug administration]
Safety of Besifovir administered orally will be assessed by incidence of treatment emergent adverse event [TEAE]'s, abnormalities in vital sign assessments, ECG's, clinical laboratory assessments, and physical exams
