About this trial

Master Protocol: The main goal of this master clinical study is to evaluate the safety, tolerability, efficacy, and pharmacokinetic (PK) of long-acting oral (LAO) regimens in people with HIV-1 (PWH).

The main goal of this Substudy-01 is to assess the safety, tolerability, effectiveness, and PK of switching to weekly LAO regimens, including GS-3242 + LEN, versus continuing on once daily oral bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF; coformulated; Biktarvy®) in PWH with controlled HIV infection, B/F/TAF for at least 6 months prior to study start.

The primary objective is to evaluate the efficacy of switching to each LAO regimen versus continuing B/F/TAF in virologically suppressed PWH at Week 24.
