About

The goal of this clinical study is to learn more about the effects of switching to the study drugs, bictegravir (BIC) plus lenacapavir (LEN), versus current therapy (Phase 2) and BIC/LEN fixed-dose combination (FDC) versus current therapy (Phase 3) in people living with HIV (PWH).

Inclusion and exclusion criteria

Key Inclusion Criteria:

  • If plasma HIV-1 RNA measurements in the 6 months prior to screening are available, all levels must be < 50 copies/mL.

  • At least one documented plasma HIV-1 RNA level measured between 6 and 12 months (± 2 months) prior to screening. This and any other HIV-1 RNA measurements documented in this period must be < 50 copies/mL

  • Plasma HIV-1 RNA levels < 50 copies/mL at screening.

  • Currently receiving a complex antiretroviral (ARV) regimen due to previous viral resistance, or intolerance, or contraindication to existing single-tablet regimens (STR), and on this regimen for at least 6 months prior to the screening visit. The criteria to define a complex regimen in this study are as follows:

    • A regimen containing a boosted protease inhibitor or a nonnucleos(t)ide reverse transcriptase inhibitor (NRTI) plus at least 1 other third agent (ie, an agent from a class other than NRTIs) (eg, bictegravir/emtricitabine/tenofovir alafenamide (coformulated; Biktarvy®)(BVY) + darunavir/cobicistat, BVY + etravirine), or
    • A regimen of ≥ 2 pills/day, or a regimen requiring dosing more than once daily, or
    • A regimen containing parenteral agent(s) (excluding a complete long-acting injectable regimen, such as intramuscular cabotegravir plus rilpivirine) as well as oral agents.
  • No documented or suspected resistance to bictegravir (BIC).

  • Estimated glomerular filtration rate ≥ 15 mL/min according to the Cockcroft-Gault formula for creatinine clearance (CLcr) who are not on renal replacement therapy.

Key Exclusion Criteria:

  • Prior use of, or exposure to, lenacapavir (LEN)
  • Active tuberculosis infection
  • Chronic hepatitis B virus (HBV) infection

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

671 participants in 5 patient groups

Phase 2: Bictegravir (BIC) 75 mg + Lenacapavir (LEN) 25 mg
Experimental group
Description:
Participants will switch from their stable baseline regimen (SBR) to a regimen of BIC 75 mg + LEN 25 mg. Participants will receive a 2-day loading dose regimen of LEN 600 mg, in addition to the daily doses of BIC 75 mg + LEN 25 mg starting on Day 1 up to the end of randomized treatment (ERT) visit, participants will be treated for at least 24 weeks during the Randomized Period. Following Randomized Period, the participants will have an option to participate in an Extension Period to receive BIC/LEN 75 mg/50 mg fixed dose combination (FDC).
Treatment:
Drug: Lenacapavir
Drug: Bictegravir
Phase 2: BIC 75 mg + LEN 50 mg
Experimental group
Description:
Participants will switch from their SBR to a regimen of BIC 75 mg + LEN 50 mg. Participants will receive a 2-day loading dose regimen of LEN 600 mg, in addition to the daily doses of BIC 75 mg + LEN 50 mg starting on Day 1 up to the ERT visit, participants will be treated for at least 24 weeks during the Randomized Period. Following Randomized Period, the participants will have an option to participate in an Extension Period to receive BIC/LEN 75 mg/50 mg FDC.
Treatment:
Drug: Lenacapavir
Drug: Bictegravir
Phase 2: Stable Baseline Regimen (SBR)
Active Comparator group
Description:
Participants will continue with their SBR per prescription for up to the ERT visit, participants will be treated for at least 24 weeks during the Randomized Period. Following Randomized Period, the participants will have an option to participate in an Extension Period to receive BIC/LEN 75 mg/50 mg FDC.
Treatment:
Drug: Stable Baseline Regimen
Phase 3: BIC/LEN 75 mg/50 mg Fixed-dose Combination (FDC)
Experimental group
Description:
Participants will switch from their SBR to a regimen of BIC/LEN 75 mg/50 mg FDC. Participants will receive a 2-day loading dose regimen of LEN 600 mg, in addition to the daily doses of BIC/LEN 75 mg/50 mg FDC starting on Day 1 up to the ERT visit, participants will be treated for at least 48 weeks during the Randomized Period. Following Randomized Period, the participants will have an option to participate in an Extension Period to receive BIC/LEN 75 mg/50 mg FDC.
Treatment:
Drug: BIC/LEN FDC
Phase 3: Stable Baseline Regimen
Active Comparator group
Description:
Participants will continue with their SBR per prescription for up to the ERT visit, participants will be treated for at least 48 weeks during the Randomized Period. Following Randomized Period, the participants will have an option to participate in an Extension Period to receive BIC/LEN 75 mg/50 mg FDC.
Treatment:
Drug: Stable Baseline Regimen
