Brief summary
This is a two-part study. Part 1 will evaluate relative bioavailability of temsavir (TMR) following single dose administration of the reference fostemsavir (FTR) compared to two low-dose ER tablet formulations of FTR. In Part 2, the effect of food on the bioavailability of TMR will be assessed on the selected low-dose ER tablet formulation from Part 1.
Interventions
Fostemsavir tablets will be administered via oral route.
Fostemsavir tablets will be administered via oral route.

Primary
| Measure | Time frame |
|---|---|

| Part 1: AUC from time zero extrapolated to infinite time (AUC[0-infinity]) of temsavir | Predose (Day 1) until 72 hour post dose |
| Part 1: Maximum observed plasma concentration (Cmax) | Predose (Day 1) until 72 hour post dose |
Secondary
| Measure | Time frame |
|---|---|
