- Pharmacokinetic (PK) Parameter: Cmax of Islatravir (ISL) and Lenacapavir (LEN) [ Time Frame: Day 1 up to Week 36 ]Cmax is defined as the maximum observed concentration of drug.
- PK Parameter: Tmax of ISL and LEN [ Time Frame: Day 1 up to Week 36 ]Tmax is defined as the time (observed time point) of Cmax.
- PK Parameter: Ctau of ISL and LEN [ Time Frame: Day 1 up to Week 36 ]Ctau is defined as the observed drug concentration at the end of the dosing interval.
- PK Parameter: AUCtau of ISL and LEN [ Time Frame: Day 1 up to Week 36 ]AUCtau is defined as concentration of drug over time (the area under the concentration verses time curve over the dosing interval).
- PK Parameter: t1/2 of ISL and LEN [ Time Frame: Day 1 up to Week 36 ]t1/2 is defined as the estimate of the terminal elimination half-life of the drug.
