Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a phase I, randomized, double-blind, placebo-controlled clinical trial to investigate the safety of VRC07-523LS and PGDM1400LS in combination with ChAdOx1.tHIVconsv1, ChAdOx1.HIVconsv62 prime, MVA.tHIVconsv4 and A244d11gp120/ALFQ vaccination, and the impact on viral load setpoint during analytic treatment interruption (ATI) in people living with human immunodeficiency virus-1 (HIV-1, PLWH) who have initiated or will initiate antiretroviral therapy (ART) during acute HIV-1 infection (AHI).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a phase I, randomized, double-blinded, placebo-controlled clinical trial to investigate the safety of VRC07-523LS and PGDM1400LS in combination with ChAdOx1.tHIVconsv1, ChAdOx1.tHIVconsv62, MVA.tHIVconsv4 and A244d11 gp120/ALFQ vaccination, and the impact on viral load setpoint during ATI in PLWH who initiated ART during AHI.

To evaluate the primary objectives, the study will enroll up to 40 adults already enrolled in the RV 254/WRAIR #1494 study who initiated ART during Fiebig I-V acute HIV-1 infection, with plasma HIV-1 RNA \< 50 copies/mL for ≥ 48 weeks, CD4 T-cell counts ≥ 400 cells/mm3, viruses susceptible to VRC07-523LS and/or PGDM1400LS, and the absence of known protective HLA allele (Groups 1 and 2).

Participants currently on ART who meet study entry criteria will be randomized (Section 6.2) in a 1:1 allocation to the Active (Group 1) or Comparator (Group 2) Arms prior to entering Step 1.

To evaluate exploratory objectives, the study will also enroll up to 8 adults who are newly enrolled in the RV 254/WRAIR #1494 study, diagnosed during Fiebig I-V AHI, and have not yet initiated ART (Group 3).

Participants Caregivers Investigators
The participants, clinical staff, laboratory staff, Principal Investigator (PI) and the Sponsor will be blinded to vaccine/placebo allocation for Groups 1 and 2. The pharmacist with primary responsibility for vaccine dispensing will not be blinded to the treatment and maintains the randomization code and completes assignments of participants according to the randomization allocation.

The contents of the syringes containing vaccine IP will be obscured and not discernable to the participant or study staff in the vaccination room. All analyses conducted prior to the completion of the study will be performed by an unblinded statistician, and results will only be presented in aggregate to protect the participant-level blind. See Section 6.4 below for unblinding procedures.

Group 3 will be unblinded.
