- Brief Summary
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
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).
