Substudy-01: A Study of Long-Acting HIV-1 Treatments Taken by Mouth in People With HIV-1 With Undetectable Virus Levels
A Platform, Active-Controlled Study Evaluating the Safety and Efficacy of Long-Acting Oral Regimens in People With HIV-1; Substudy-01: Phase 2, Open-Label, Weekly, Long-Acting, Oral Regimens in Virologically Suppressed People With HIV-1
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.

Experimental: Treatment Arm B: GS-3242 + LEN
Participants will be randomized to oral loading dose of GS-3242 in combination with LEN, followed by a once-weekly oral combination regimen of GS-3242 and LEN (at a different dose than Treatment C), administered concomitantly for at least 48 weeks. After Week 48, participants in the Randomized Phase may be offered to continue to receive study drug in the Extension Phase. |
