Phase 2a Clinical Trial to Evaluate the Safety and Immunogenicity of Polyvalent Env (A, B, C, A/E) / Gag (C) DNA and gp120 (A, B, C, A/E) Protein HIV-1 Vaccines (PDPHV) With Either Alhydrogel or GLA-SE in Healthy Adults Living Without HIV
Worcester HIV Vaccine
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.
Description
Participants will be enrolled in Group 1 to group 5. Within each group, participants will be randomly assigned to either Treatment or Placebo Control. Group 1 (Sentinel group) will be enrolled first to test the safety of the protein vaccines mixed with the Alhydrogel adjuvant. Participants in Group 1 (Treatment) will receive polyvalent gp120 (A, B, C, A/E) protein vaccines mixed with Alhydrogel in the non-dominant arm at months 0, and 3. Participants in Group 1 (Control) will receive placebo at months 0, and 3. The Safety Monitoring Board (SMB) will evaluate the safety profile of volunteers…

Interventions
- BiologicalPDPHV 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.
- BiologicalPDPHV 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.
