This randomized double-blind study aimed to determine the safety and immunogenicity of a gp120/NefTat candidate human immunodeficiency virus type 1 (HIV-1) vaccine formulated with one of three different Adjuvant Systems (AS02(A), AS02(V) and AS01(B)) in healthy HIV-seronegative adults. All vaccine formulations induced strong HIV-specific CD4(+) T-cell responses characterized by high lymphoproliferative capacity and IL-2 production that were still detectable 18 months after last immunization, with strongest responses seen in the AS01(B) group. Broad coverage was demonstrated against gp120, and to a lesser extent Nef, derived from the most common circulating clades (B, C and circulating recombinant form [CRF]-01). All vaccine formulations exhibited acceptable safety and reactogenicity profiles. The demonstration of superior CD4(+) T-cell induction by AS01(B) provides important guidance for future HIV vaccine development.
