Overview
RHIVIERA-02 trial is a placebo-controlled double-blinded two arm prospective phase II trial. This study will test the use of broadly neutralising antibodies (bNAbs) in participants, at primary HIV infection (PHI) and ART initiation.
Description
The study proposes to test an intervention consisting of dual long-acting HIV-specific broadly neutralizing antibodies (3BNC117-LS & 10-1074-LS ) + ART, at primary HIV-1 infection, and to compare it to ART only regarding HIV-1 replication.
The study aims to enrol 69 participants in French (Ile-de-France) clinical centres. Participants will have been diagnosed with primary HIV-1 infection, will start ART during early phase of Primary HIV infection, and will interrupt ART 52 weeks later.
Study duration will vary by participant, depending on the time of ART interruption and the time to viral rebound.
