About this trial

The goal of this clinical study is to compare how effective a long-acting treatment of injectable combination of lenacapavir (LEN), teropavimab (TAB), and zinlirvimab (ZAB) is versus continuing a daily oral HIV treatment in adults with HIV-1 whose virus is already well controlled, after 1 year (52 weeks) of treatment.

The primary objective of this study is to evaluate the efficacy of switching to the regimen of LEN, TAB, and ZAB versus continuing an oral stable baseline regimen (SBR) in virologically suppressed people with HIV-1 (PWH) as determined by the proportion of participants with HIV-1 RNA ≥ 50 copies/mL at Week 52.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Plasma HIV-1 RNA levels < 50 copies/mL 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.

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).

Disqualifiers

History of an opportunistic infection or illness indicative of Stage 3 HIV disease.

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.
