Summary

The purpose of the study is to evaluate the safety, tolerability, and immunogenicity of polyvalent env (A,B,C,A/E)/gag (C) DNA prime and gp120 (A,B,C,A/E) protein HIV-1 vaccines boost (PDPHV) with either Alhydrogel or GLA-SE in healthy, HIV-uninfected adults.

Volunteers will receive either the PDPHV or the placebo (normal saline) by intramuscular injections. Some volunteers will receive Alhydrogel and others will receive GLA-SE as part of the protein boost.

Conditions

  • HIV Prevention

Interventions

BIOLOGICAL

PDPHV Plasmid DNA Vaccines (env (A, B, C, A/E)/gag (C))

The polyvalent DNA Vaccines contains equal amounts of 5 individual DNA plasmid components utilizing the same vector pSW3891. Four plasmids each containing a codon optimized gp120 gene sequence from HIV-1 subtype A, B, C and CRF01\_AE consensus, and a fifth plasmid containing a codon optimized gag gene from subtype C.

BIOLOGICAL

PDPHV Recombinant Protein Vaccines (gp120 (A, B, C, A/E))

The Recombinant Protein Vaccines (gp120 (A, B, C, A/E)) contains equal amounts of 4 gp120 proteins.

BIOLOGICAL

Alhydrogel adjuvant

PDPHV protein vaccines adjuvant

BIOLOGICAL

GLA-SE adjuvant

PDPHV protein vaccines adjuvant

BIOLOGICAL

Placebo for DNA Vaccines, Protein Vaccines and Adjuvants

Sodium Chloride for Injection, USP 0.9%.
