Study of an Injectable Regimen of GS-3242 With Lenacapavir Compared to Biktarvy in People New to HIV-1 Treatment
Sponsor: Gilead Sciences
Summary
The study will have two portions: Phase 2 and Phase 3. Phase 2 will further have 2 parts: Part A and Part B. The goal of Phase 2, Part A is to assess the effectiveness of study drugs GS-3242 plus Lenacapavir (LEN) versus Biktarvy (bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF)), in people with HIV-1 (PWH) who are new to treatment. This will be done in Treatment Groups 1, 2 and 3 at Week 35. The goal of Phase 2, Part B is to compare the effectiveness of study drugs, GS-3242 and LEN versus B/F/TAF in Groups 4 and 3 at Week 26. The goal of Phase 3 is to assess the long-term effectiveness of study drug GS-3242 and LEN versus B/F/TAF, at Week 52. The primary objectives of this study are: Phase 2, Part A: To evaluate the efficacy of intramuscular (IM) GS-3242 plus IM LEN versus B/F/TAF in treatment-naive people with HIV-1 (PWH) in Treatment Groups 1, 2, and 3 at Week 35. Phase 2, Part B: To evaluate the efficacy of IM GS-3242 plus IM LEN versus B/F/TAF in treatment-naive PWH in Treatment Groups 4 and 3 at Week 26. Phase 3: To evaluate the efficacy of IM GS-3242 plus IM LEN versus B/F/TAF in treatment-naive PWH at Week 52.
