EU CTIS ID: 2025-524336-19-00
What this study is testing
To evaluate the efficacy of switching to the regimen of LEN, TAB, and ZAB versus continuing an oral SBR in virologically suppressed PWH as determined by the proportion of participants with HIV-1 RNA ≥ 50 copies/mL at Week 52.
- Therapeutic confirmatory (Phase III)

Who can take part
You may be able to join if
- General G1. Participants assigned male or female at birth, 18 years of age or older at screening, able to understand and give written informed consent and comply with treatment and follow-up.
- G2. Participants assigned female at birth who are of childbearing potential and engage in heterosexual intercourse must agree to use protocol-specified method(s) of contraception as described in Appendix 11.4.
- Medical History/Physical Characteristics MH1. Body weight ≥ 35 kg at screening.
- MH2. HIV-1 susceptibility results from screening meeting specific criteria: Proviral phenotypic susceptibility to both TAB and ZAB by the investigational PhenoSense HIV mAb Assay (Labcorp Monogram Biosciences) at screening. TAB phenotypic susceptibility is defined as IC90 ≤ 2 µg/mL; ZAB phenotypic susceptibility is defined as IC90 ≤ 2 µg/mL.
- MH3. Plasma HIV-1 RNA levels < 50 copies/mL at screening (SV2).
- MH4. At least 1 documented HIV-1 RNA level measured between 6 months and 12 months (+ 2 months) prior to screening (SV1). 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.
You likely can't join if
- Medical Conditions/History MC1. History of an opportunistic infection or illness indicative of Stage 3 HIV disease.
- Prior/Concurrent Therapy or Clinical Study Experience PT1. Prior use of, or exposure to, LEN or a bNAb for HIV-1.
- PT2. Prior use of, or exposure to, ibalizumab fostemsavir, or maraviroc.
- PT3. Baseline regimen consisting of monotherapy with any single ARV.
- PT4. 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.
- PT5. Requirement for ongoing therapy with or prior use of any prohibited medications listed in Section 5.3.1.

- MH5. 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 SV1. 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).
- MH6. On a stable oral ART for ≥ 6 months prior to screening. A change in ART regimen ≥ 3 months prior to the screening visit for reasons other than VF (eg, tolerability, simplification, DDI profile) is allowed; participants 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 SV1 and Day 1.
- Laboratory Assessments LA1.For participants of childbearing potential, a negative serum pregnancy test at screening, prior to Day 1 randomization, and enrollment (per Appendix 11.4). A negative urine pregnancy test is required on Day 1 visit prior to the dosing of study drugs.
