Primary Endpoints
Percentage of Participants With Human Immunodeficiency Virus Type 1 (HIV-1) Ribonucleic Acid (RNA) ≥ 50 Copies/mL at Week 26 as Determined by the United States Food and Drug Administration (US FDA)-Defined Snapshot Algorithm
Week 26

Percentage of participants with HIV-1 RNA ≥ 50 copies/mL at Week 26 was analyzed using US FDA-defined snapshot algorithm, which defines a participant's virologic outcome and included participants a) who had last available on-treatment HIV-1 RNA ≥ 50 copies/mL in the Week 26 analysis window; or b) who did not have on-treatment HIV-1 RNA data in the Week 26 analysis window and i) discontinued study drug prior to or in the Week 26 analysis window due to lack of efficacy, or ii) discontinued study drug prior to or in the Week 26 analysis window due to adverse event (AE) or death and had last available on-treatment HIV-1 RNA ≥ 50 copies/mL, or iii) discontinued study drug prior to or in the Week 26 analysis window due to reasons other than AE, death, or lack of efficacy and had the last available on-treatment HIV-1 RNA ≥ 50 copies/mL. Clopper-Pearson exact method was used to calculate the 95% confidence interval (CI) for the outcome measure of each treatment. Percentages were rounded off.

ArmTypeDescription
Randomized Phase Treatment Group 1: LEN + TAB + ZABEXPERIMENTALParticipants will receive loading dose of lenacapavir (LEN) 600 mg tablets, orally, on Day 1 and Day 2. They will receive LEN 927 mg subcutaneous (SC) injection along with teropavimab (TAB) 2550 mg intravenous (IV) infusion and zinlirvimab (ZAB) 2550 mg IV infusion on Day 1 and every 26 weeks up to Week 52 in the Randomized Phase. At Week 52, participants in this group with HIV-1 RNA \< 50 copies/mL will be given the option to participate in the study extension phase. In the study extension phase, participants will continue to receive their randomized study drugs every 26 weeks.
Randomized Phase Treatment Group 3: SBREXPERIMENTALParticipants in Stay on Baseline Regimen (SBR) group will continue their baseline oral antiretroviral therapy (ART) up to Week 52. Antiretroviral therapy will include drugs like bictegravir/emtricitabine/tenofovir alafenamide, darunavir/cobicistat/emtricitabine/tenofovir alafenamide, dolutegravir/abacavir lamivudine, and rilpivirine/emtricitabine/tenofovir alafenamide, administered as per standard of care. At Week 52, participants in this group with HIV-1 RNA \< 50 copies/mL and in the absence of confirmed virologic rebound throughout the Randomized Phase of the study will switch from oral ART to LEN, TAB and ZAB, every 26 weeks. The participants will switch to receive LEN, TAB, and ZAB every 26 weeks beginning at Week 52.
Extension Phase: Treatment Group 1: LEN + TAB + ZABEXPERIMENTALAt Week 52, participants in this group with HIV-1 RNA \< 50 copies/mL will be given the option to participate in the study extension phase. In the study extension phase, participants will receive LEN 927 mg SC, TAB 2550 mg IV infusion and ZAB 2550 mg IV infusion.
Extension Phase Treatment Group 3: SBREXPERIMENTALAt Week 52, participants in this group will be given the option to participate in the Extension Phase to switch from oral ART to LEN 927 mg SC, TAB 2550 mg IV infusion and ZAB 2550 mg IV infusion, every 26 weeks at the dose specified for Treatment Group 1.
