- •At least 18 years of age at screening
- •Increased likelihood of HIV acquisition as indicated by at least one of the following: a) Condomless sex with ≥ 2 partners in the past 6 months b) Diagnosis of a bacterial sexually transmitted infection (STI) in the past 12 months c) Engagement in sex work or transactional sex in the past 12 months d) Use of ≥ 2 courses of nonoccupational HIV postexposure prophylaxis (nPEP) in the past 12 months e) Condomless sex with a partner living with HIV who has unknown or unsuppressed viral load (≥ 200 copies/mL) in the past 12 months
- •Negative local rapid HIV-1/2 antibody (Ab)/antigen (Ag) test, central HIV-1/2 Ab/Ag, and HIV-1 RNA quantitative nucleic acid amplification testing (NAAT) at screening
- •Estimated glomerular filtration rate (eGFR) at least 60 mL/min at screening according to the Cockcroft-Gault formula for creatinine clearance (CLcr): (140 - age in years) × (weight in kg) x [0.85 if female] = CLcr (mL/min) 72 × (serum creatinine in mg/dL)
- •Body weight at least 35 kg
- •Willing and able to follow study procedures
- •Participants of childbearing potential who are receiving teratogenic medications, including testosterone, who engage in frontal (vaginal) intercourse must not intend to become pregnant during the study and must agree to utilize protocol-specified method(s) of contraception as described in Appendix 11.
- •of the Protocol.
Exclusion Criteria
- •Coenrollment in any other clinical study (including observational) without prior approval from the sponsor is prohibited while participating in this study.
- •Have a history of osteoporosis or bone fragility fractures.
- •Current alcohol or substance abuse judged by the investigator to be problematic such that it potentially interferes with participant study adherence.
- •Grade 3 or Grade 4 proteinuria or glycosuria at screening that is unexplained or not clinically manageable.Grade 3 or Grade 4 proteinuria or glycosuria at screening that is unexplained or not clinically manageable.
- •Participants of childbearing potential who are pregnant or lactating at screening or on Day
- •Participants of childbearing potential must have a negative pregnancy test at screening and on Day 1 (see “Definition of Childbearing Potential” in Appendix 11.4 of the Protocol).
- •Any other clinical condition, laboratory abnormalities, or psychosocial 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.
- •Known hypersensitivity to the study drug, the metabolites, or formulation excipient.
- •Current use of PrEP, defined as self-report of the use of PrEP in the preceding 4 weeks. PrEP should not be discontinued to facilitate study participation.
- •Current use of nPEP, unless the prescribed course will be completed prior to randomization.
- •Past or current participation in HIV vaccine or HIV broadly neutralizing Ab study unless participant provides documentation of receipt of placebo (ie, not active product).
- •Acute viral hepatitis A, B, or C or evidence of chronic hepatitis B or C infection a) If a participant has a negative hepatitis B surface antigen (HBsAg), negative hepatitis B surface antibody (HBsAb), and positive hepatitis B core antibody (HBcAb), hepatitis B virus (HBV) DNA testing will be completed. If the HBV DNA result is positive, the participant is a screen failure. Participants found to be susceptible to HBV infection will be offered HBV vaccination. b) If the hepatitis C virus (HCV) Ab result is positive, then HCV RNA will be evaluated. Participants found to be positive for HCV at screening must not have active infection or must have completed treatment and achieved a sustained virologic response.
- •Severe hepatic impairment or a history of or current clinical decompensated liver cirrhosis (eg, ascites, encephalopathy, variceal bleeding).
- •Have a suspected or known active, serious infection(s) (eg, active tuberculosis, etc).
- •Need for continued use of any contraindicated concomitant medications.
