AUCtau is defined as concentration of drug over time (the area under the concentration verses time curve over the dosing interval). AUCtau for ATV (Cohorts 1 Part A, 2, 3, and 4 \[Groups 2 to 4\]); DRV (Cohorts 1 Part A, 2, and 3); TAF (Cohorts 2, 3, 4 \[Groups 1 to 4\] and 5 \[Groups 1 to 3\] taking F/TAF); and TFV (Cohorts 2, 3, 4 \[Groups 1 to 4\] and 5 \[Groups 1 to 3\] taking F/TAF) will be reported.
