Safety and immunogenicity of CD40.HIVRI.Env, a dendritic cell-based HIV vaccine, in healthy HIV-uninfected adults: a first-in-human randomized, placebo-controlled, dose-escalation study (ANRS VRI06).

ABSTRACT:

Background

Current HIV prophylactic vaccines evaluate HIV Env as purified proteins. CD40.HIVRI.Env is an innovative antigen delivery targeting gp140 Env from HIV Clade C 96ZM651 to CD40-expressing antigen-presenting cells, thus harnessing the intrinsic immune-stimulant properties. DNA-HIV-PT123 vaccine encodes 96ZM651 gp140/Gag and 97CN54 Pol/Nef.

Methods

Seventy-two HIV-negative volunteers were enrolled between 05/2021 and 10/2022 in a phase 1 placebo-controlled trial conducted in France and Switzerland (N° EudraCT: 2020-001814-40; NCT04842682). Volunteers were randomized (5:1 active versus placebo) in groups receiving either 0.3, 1.0, or 3.0 mg CD40.HIVRI.Env (Hiltonol® adjuvanted) alone or co-administered with DNA-HIV-PT123 at weeks (W) 0, 4, and 24.
