Study Details

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.

Arms

  • Experimental: Phase 2: Part A: Group 1 of GS-3242 + LEN
    Participants will be randomized to receive oral loading doses of GS-3242 in combination with LEN oral tablets, followed by intramuscular (IM) injections of GS-3242 and LEN for at least 52 weeks.
  • Experimental: Phase 2: Part A: Group 2 of GS-3242 + LEN
    Participants will be randomized oral loading doses of GS-3242 in combination with LEN oral tablets, followed by IM injections of GS-3242 (at a different dose than Group 1) and LEN for at least 52 weeks.
  • Experimental: Phase 2: Part A: Group 3 of B/F/TAF
    Participants will be randomized to receive 50/200/25 mg of B/F/TAF daily for at least 52 weeks.
  • Experimental: Phase 2: Part B: Group 4 of GS-3242 + LEN
    Participants will be enrolled (non-randomized) to receive oral loading doses of GS-3242 in combination with LEN oral tablets, followed IM injections of GS-3242 and LEN (at different doses than Group 1 and 2) for at least 52 weeks.
  • Experimental: Phase 3: Group 1 of GS-3242 + LEN
    Participants will be randomized to receive oral loading doses of GS-3242 in combination with LEN oral tablets, followed by IM injections of GS-3242 and LEN for at least 104 weeks.
  • Experimental: Phase 3: Group 2 of B/F/TAF
    Participants will be randomized to receive 50/200/25 mg of B/F/TAF daily for at least 104 weeks.
