Criteria
Inclusion Criteria
  • Is confirmed HIV-uninfected based on negative HIV-1/HIV-2 test result before allocation to study intervention.
  • Is on stable GAHT and does not intend to change therapy through Week 4 of the study.
  • Has a low-risk of HIV infection.
  • Identifies with a gender that is different from that assigned at birth.
  • A participant assigned female at birth is eligible if not pregnant or chest-feeding and is not of childbearing potential (POCBP) or: Is a POCBP and using an acceptable contraceptive method, or be abstinent from penile-vaginal intercourse with an individual capable of producing sperm (abstinent on a long term and persistent basis); a POCBP must have a negative highly sensitive pregnancy test ([urine or serum] as required by local regulations) within 24 hours before the first dose of study intervention; If a urine test cannot be confirmed as negative (e.g, an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive; the investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a participant assigned female at birth with an early undetected pregnancy; contraceptive use by participant assigned female at birth should be consistent with local regulations.
Exclusion Criteria
  • Has known current or chronic history of liver disease (e.g, non-alcoholic or alcoholic steatohepatitis) or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome, asymptomatic gallstones, or cholecystectomy), unless the participant has stable liver function tests and no evidence of hepatic synthetic dysfunction.
  • Has a history of malignancy within 5 years of screening except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, or in situ anal cancers.
  • Has taken cabotegravir, lenacapavir, or any other long-acting HIV prevention product at any time (past or current use).
  • Is currently participating in or has participated in a clinical study with an investigational compound or device, within 30 days before Day 1 through the duration of the study.
