Inclusion and exclusion criteria

Key Inclusion Criteria:

  • Received bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) for ≥ 24 weeks at screening.
  • Documented plasma human immunodeficiency virus type 1 (HIV-1) ribonucleic acid (RNA) < 50 copies/mL (or undetectable HIV-1 RNA level according to the local assay being used if the limit of detection is ≥ 50 copies/mL) for ≥ 24 weeks before and at screening.
  • Plasma HIV-1 RNA < 50 copies/mL at screening.

Key Exclusion Criteria:

  • History of prior virologic failure while receiving treatment for HIV-1.

  • Prior use of, or exposure to, islatravir (ISL) or lenacapavir (LEN).

  • Active, serious infections requiring parenteral therapy < 30 days before randomization.

  • Active or occult hepatitis B virus (HBV) coinfection, defined as hepatitis B core antibody (HBcAb) positive, hepatitis B surface antigen (HBsAg) positive, or HBV deoxyribonucleic acid (DNA) positive as determined by the central laboratory.

  • Active hepatitis C virus (HCV) coinfection, defined as detectable HCV RNA.

  • Any of the following laboratory values at screening:

    • Creatinine clearance (CLcr) ≤ 30 mL/min according to the Cockcroft-Gault formula
  • CD4+ T-cells < 200 cells/mm^3 (Cohort 1); CD4+ T-cells < 350 cells/mm^3 (cohort 2).

  • Absolute lymphocyte count < 900 cells/mm^3 (cohort 2).

  • Individuals of childbearing potential (as defined in protocol) who have a positive serum pregnancy test at screening or positive urine and serum pregnancy tests at Day 1 prior to study drug administration.

  • Individuals who plan to continue breastfeeding during the study.

  • Documented historical or screening resistance reports showing nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) or non-nucleoside/nucleotide reverse transcriptase inhibitors (NNRTIs) resistance mutations in reverse transcriptase, including M184V/I (Cohort 2).

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