Study Details

The study will have two parts: Part A and Part B. In Part A, the goal of the study is to compare the effectiveness of switching to the study drugs GS-3242 plus Lenacapavir (LEN) versus continuing Biktarvy (bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF)), in virologically suppressed people with HIV-1 (PWH) in treatment Group 1, 2 and 3 at Week 35. In Part B the goal of the study is to compare the effectiveness of switching to the study drugs, GS-3242 and LEN versus continuing B/F/TAF in Groups 4 and 3 at Week 26. The primary objective of part A is to evaluate the efficacy of switching to intramuscular (IM) GS-3242 plus IM LEN versus continuing on B/F/TAF PWH who are virologically suppressed in treatment Groups 1, 2, and 3 at Week 35 and Part B is to evaluate the efficacy of switching to IM GS-3242 plus IM LEN versus continuing on B/F/TAF in PWH who are virologically suppressed in Treatment Groups 4 and 3 at Week 26.

Arms

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

Primary Outcome Measure
