About

The goal of this clinical study is to learn more about the effects of switching to the study drugs, bictegravir (BIC)/lenacapavir (LEN), fixed-dose combination (FDC) versus current therapy bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) FDC in people living with HIV-1 (PWH).

The primary objective of this study is to learn how effective it is to switch to BIC/LEN FDC tablets versus continuing on B/F/TAF FDC tablets in virologically suppressed PWH.

Inclusion and exclusion criteria

Key Inclusion Criteria:

  • Currently receiving B/F/TAF for at least 6 months prior to screening.
  • If plasma human immunodeficiency virus type 1 (HIV-1) ribonucleic acid (RNA) measurements in the last 6 months prior to screening are available, all levels must be < 50 copies/mL.
  • At least one documented 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.
  • No documented or suspected resistance to BIC (including integrase strand-transfer inhibitor resistant (INSTI-R) mutations T66A/I/K, E92G/Q, G118R, F121Y, Y143C/H/R, S147G, Q148H/K/R, N155H/S, or R263K in the integrase gene).
  • No documented or suspected resistance to tenofovir alafenamide (TAF) (TAF; mutations K65R, K65N, K70E, Q151M or T69 insertion, or ≥ 3 of the following thymidine analog mutations [M41L, D67N, K70R, L210W, T215Y/F, K219Q/E/N/R] in the reverse transcriptase gene).
  • Estimated glomerular filtration rate ≥ 30 mL/min according to the Cockcroft-Gault formula for creatinine clearance.

Key Exclusion Criteria:

  • Positive serum pregnancy test or pregnant at screening or a positive pregnancy test prior to Day 1 randomization.

  • Breastfeeding (nursing).

  • Prior use of, or exposure to, LEN.

  • Active, serious infections (other than HIV-1) requiring parenteral therapy < 30 days prior to randomization.

  • Active tuberculosis infection.

  • Acute hepatitis < 30 days before randomization.

  • Chronic hepatitis B virus (HBV) infection, as determined by either:

    • Positive HBV surface antigen and negative HBV surface antibody, regardless of HBV core antibody status, at the screening visit.
    • Positive HBV core antibody and negative HBV surface antibody, regardless of HBV surface antigen status, at the screening visit.
  • Known hypersensitivity to the study drug, its metabolites, or any formulation excipient.

  • History of or current clinical decompensated liver cirrhosis (eg, ascites, encephalopathy, or variceal bleeding).

  • Abnormal electrocardiogram (ECG) at the screening visit that is clinically significant as determined by the investigator.

  • Active malignancy requiring acute systemic therapy.

  • Any of the following laboratory values at screening:

    • Alanine aminotransferase > 5 × upper limit of normal (ULN).
    • Direct bilirubin > 1.5 × ULN.
    • Platelets < 50,000/mm^3.
    • Hemoglobin < 8.0 g/dL.
  • Requirement for ongoing therapy with or prior use of any prohibited medications listed in the protocol.

  • Participation or planned participation in any other clinical study (including observational studies) without prior approval from the sponsor.

  • Any other clinical condition or prior therapy that, in the opinion of the investigator, would make the participant unsuitable for the study or unable to comply with dosing requirements.

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

546 participants in 2 patient groups

Treatment Group 1: Bictegravir (BIC)/ Lenacapavir (LEN) (75/50 mg) + PTM B/F/TAF
Experimental group
Description:
Blinded Phase: Participants will switch from bictegravir/emtricitabine/tenofovir (B/F/TAF) FDC tablets to BIC/LEN (75/50 mg) FDC tablets and placebo-to-match (PTM) B/F/TAF. Participants will receive a 2-day oral loading dose of LEN 600 mg on Day 1 and on Day 2, in addition to the daily doses of BIC/LEN FDC tablet starting on Day 1 up to end of blinded treatment (EBT) visit. Open-label (OL) Phase: Following treatment in the Blinded Phase, participants from Treatment Group 1 will receive BIC/LEN FDC tablets through Week 48 in the Open-label Phase. At the OL Week 48 visit, participants from Treatment Group 1 will be given the option to continue to receive BIC/LEN FDC tablets until the conclusion of the OL Phase.
Treatment:
Drug: Lenacapavir
Drug: Bictegravir
Drug: Placebo to match B/F/TAF
Treatment Group 2: B/F/TAF (50/200/25 mg) + PTM BIC/LEN
Experimental group
Description:
Blinded Phase: Participants will continue with their B/F/TAF (50/200/25 mg) FDC tablets and start PTM BIC/LEN tablets on Day 1. Participants will receive PTM LEN tablets for 2 days (2 PTM LEN tablets on Day 1 and on Day 2. The blinded phase will continue until the EBT visit. Open Label Phase: Participants in Treatment Group 2 who complete the EBT visit will be given the option to enter the OL phase to receive BIC/LEN FDC tablets until the conclusion of the OL Phase.
Treatment:
Drug: Placebo to match BIC/LEN
Drug: Lenacapavir
Drug: Bictegravir
Drug: B/F/TAF
