Twice-Yearly HIV shots could replace daily pills
NCT ID NCT07682961
First seen Jul 06, 2026 · Last updated Aug 14, 2026 · Updated 4 times
Summary
This phase 3 trial tests whether a combination of two antibodies (teropavimab and zinlirvimab) plus the drug lenacapavir, given as injections twice a year, can keep HIV under control in adults whose virus is already well-suppressed by daily oral medication. The study compares this approach to standard injections of cabotegravir and rilpivirine given every 8 weeks. The main goal is to see if the twice-yearly regimen is as effective at maintaining undetectable HIV levels after one year.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- lenacapavir, teropavimab, and zinlirvimab
- What this could lead to
- If successful, this could offer people with HIV a twice-yearly injection option, reducing the need for frequent shots or daily pills.
- What could go wrong
- This is a phase 3 trial, but the new combination may not be as effective as current treatments, and some participants may experience side effects or viral rebound.

Key Inclusion Criteria: * Human immunodeficiency virus type 1 (HIV-1) susceptibility results from screening meeting specific criteria: 1\) Proviral phenotypic susceptibility to both TAB and ZAB by the investigational protocol-defined assay at screening. * At least 1 documented HIV-1 RNA level measured between 6 months 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 (undetectable HIV-1 RNA level according to the local assay being used if the limit of detection is ≥ 50 copies/mL). A single virologic elevation of ≥ 50 copies/mL and \< 400 copies/mL (transient detectable viremia or "blips") prior to screening are acceptable if the subsequent plasma HIV-1 RNA level is \< 50 copies/mL. * A plasma HIV-1 RNA test \< 50 copies/mL (undetectable HIV-1 RNA level according to the local assay being used if the limit of detection is ≥ 50 copies/mL) within the last 6 months prior to screening. 1\) If \> 1 plasma HIV-1 RNA measurements in the last 6 months prior to screening are available, all must be \< 50 copies/mL (undetectable HIV-1 RNA level according to the local assay being used if the limit of detection is ≥ 50 copies/mL). * On a stable oral ARV therapy (ART) for ≥ 6 months prior to screening. 1. A change in ART regimen ≥ 3 months prior to the screening visit for reasons other than virologic failure (VF) (eg, tolerability, simplification, drug-drug interaction profile) is allowed; individuals with a change in ART regimen ≥ 3 months prior to screening must have been on the regimen for ≥ 3 months prior to screening, and all HIV-1 RNA measurements in that period must be \< 50 copies/mL. There are no permitted changes to ART regimens between screening and Day 1. Key Exclusion Criteria: * History of an opportunistic infection or illness indicative of Stage 3 HIV disease. * History of treatment failure. * Known or suspected resistance to either CAB or RPV. 1. Resistance to CAB defined as the following mutations: G118R, Q148K, Q148R, T66K+L74M, E92Q+N155H, E138A+Q148R, E138K+Q148K/R, G140C+Q148R, G140S+Q148H/K/R, Y143H+N155H, and Q148R+N155H. 2. Resistance to RPV defined as the following mutations: K101E and P; E138A, G, K, R, and Q; V179L; Y181C, I, and V; Y188L; H221Y; F227C; M230I and L, and the combination of L100I/K103N. * Individuals with a dermatologic condition or implanted prothesis overlying the gluteal injection site for CAB + RPV. * Known hypersensitivity to the study intervention, its metabolites, or formulation excipients. * Active, serious infections (other than HIV-1) requiring therapy \< 30 days prior to randomization. * Active tuberculosis infection. * Acute hepatitis of any cause \< 30 days before randomization. * History of, or current clinical decompensated liver cirrhosis (eg, ascites, encephalopathy, or variceal bleeding) or severe hepatic impairment (Child-Pugh Class C). * Active malignancy requiring acute systemic therapy. * Have poor venous access that would limit phlebotomy or intravenous (IV) infusion of study drugs. * Prior use of, or exposure to, LEN or a broadly neutralizing antibody (bNAb) for HIV-1. * Prior use of, or exposure to, long-acting (LA) injectable CAB or LA injectable RPV. * Prior use of, or exposure to, ibalizumab, fostemsavir, or maraviroc. * Baseline regimen consisting of monotherapy with any single antiretroviral (ARV). * Treatment with immunosuppressant therapies (eg, corticosteroids, immunoglobulins, and other immune- or cytokine-based therapies) within 4 weeks of screening (with the exception of a single short course of corticosteroids lasting ≤ 7 days) or have a comorbid condition with an anticipated need ongoing immunosuppressive treatment during the study. * Hepatitis C virus (HCV) antibody positive and HCV RNA detectable. * Chronic hepatitis B virus (HBV) infection, as determined by either: 1. Positive HBV surface antigen and negative HBV surface antibody, regardless of HBV core antibody status, at the screening visit. 2. Positive HBV core antibody and negative HBV surface antibody, regardless of HBV surface antigen status, at the screening visit. * Severe renal impairment-estimated glomerular filtration rate \< 30 mL/min according to the Cockcroft-Gault formula. * Abnormal electrocardiogram (ECG) at the screening visit that is clinically significant, as determined by the investigator. * Any of the following laboratory values at screening: 1. Alanine aminotransferase \> 5 x upper limit of normal (ULN). 2. Direct bilirubin \> 1.5 x ULN. 3. Platelets \< 50,000/mm\^3. 4. Hemoglobin \< 8.0 g/dL. Note: Other protocol defined Inclusion/Exclusion criteria may apply.
