Could a shot every 6 months replace daily HIV prevention pills?
NCT ID NCT06513312
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new option for preventing HIV: a shot given under the skin every 6 months, called lenacapavir. It compares how well people stick with the shot versus taking a daily pill (Truvada). About 268 people at higher risk for HIV will take part. The goal is to see if the shot is easier to use, safe, and works as well as daily pills.

Key Inclusion Criteria: * Able to comprehend and provide a signed written informed consent, which must be obtained prior to initiation of study procedures. * Cisgender men who have sex with men, transgender women, transgender men, cisgender women, and nonbinary people. * Increased likelihood of HIV acquisition as indicated by at least one of the following: 1. Condomless sex with ≥ 2 partners in the past 6 months 2. Diagnosis of a bacterial sexually transmitted infection (STI) in the past 12 months 3. Engagement in sex work or transactional sex in the past 12 months 4. Use of ≥ 2 courses of nonoccupational HIV post-exposure prophylaxis (nPEP) in the past 12 months 5. 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. 1\) If rapid HIV-1/2 Ab/Ag tests are unavailable due to extenuating circumstances, sites may run a laboratory-instrumented HIV-1/2 Ab/Ag test at their local laboratory, only if they confirm this is a fourth-generation assay and the time from blood draw to injection at any injection visit is \< 48 hours. * Estimated glomerular filtration rate (GFR) 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) Key Exclusion Criteria: * Coenrollment in any other clinical study (including observational) without prior approval from the sponsor is prohibited while participating in this study. * Known hypersensitivity to the study drug, the metabolites, or formulation excipient. * Current use of PrEP, defined as the use of PrEP in the preceding 4 weeks. PrEP should not be discontinued to facilitate study participation. For cabotegravir, this is defined as 4 weeks since the next injection was due (ie, 12 weeks since their most recent cabotegravir injection). * 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 * 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). Note: Other protocol defined Inclusion/Exclusion criteria may apply
