Официальное название

A Phase 3, Randomized, Open-label Study to Evaluate the Efficacy and Safety of Switching to Long-acting Antiretroviral Therapy of Broadly Neutralizing Antibodies Teropavimab and Zinlirvimab in Combination With the Capsid Inhibitor Lenacapavir Twice-Yearly Versus Cabotegravir and Rilpivirine Every 8 Weeks in Virologically Suppressed Adults With HIV-1 on Oral Daily Antiretroviral Therapy

Обзор

The goal of this clinical study is to compare how effective a long-acting injectable treatment of lenacapavir (LEN), teropavimab (TAB), and zinlirvimab (ZAB) versus (CAB) and rilpivirine (RPV) injections given every 8 weeks in adults with HIV-1 whose virus is well controlled on daily oral treatment, after 1 year (52 weeks) of the treatment. The primary objective of this study are to evaluate the efficacy of switching to the regimen of LEN, TAB, and ZAB versus switching to CAB and RPV 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.

Критерии участия

Критерии включения

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.

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.
