Brief summary
This Phase 1 study will evaluate the safety, tolerability, and PK of oral GS 3107 in combination with oral ECD in healthy participants. The results from this study will inform the feasibility of long interval dosing of GS 3107 with ECD for the prevention of HIV 1 infection, or to be used in combination with other antiretroviral agents for HIV 1 treatment. This study provides comparisons of PK and generates safety data for the expected therapeutic range of drug exposures planned for evaluation in subsequent studies. This is an open label study with adaptive dose selection in healthy adult participants to evaluate the PK of GS-3107 when given alone in Part D (Cohort 8).
Interventions
The study will proceed with up to 8 cohorts in 4 parts, governed by a review of safety and available PK data and applicable stopping rules. Each cohort is open label with no arms within each cohort. Dose selection, dose frequency, and meal conditions will be determined by Safety Review Team evaluation of previous dosing cohorts. Part D: Cohort 8 (GS-3107 PK) - Cohort 8: up to 900 mg GS-3107 (oral tablets) administered alone in the fasted state as a single dose Compliance and adherence is the responsibility of the investigator and site practice. The protocol does not specify specific strategies.
