Description

Summary

The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of two HIV-1 pDNA vaccines: p24CE1/2 pDNA and p55gag pDNA administered with IL-12 pDNA adjuvant, given by intramuscular (IM) injection with electroporation (EP), in healthy, HIV-uninfected adults.

Official Title

A Phase 1 Clinical Trial to Evaluate the Safety and Immunogenicity of pDNA Vaccines Expressing HIV M Group p24^Gag Conserved Elements and/or p55^Gag, Administered With IL-12 pDNA by Intramuscular Electroporation, in Healthy, HIV-Uninfected Adult Participants

Details

This study will evaluate the safety, tolerability, and immunogenicity of two HIV-1 pDNA vaccines: p24CE1/2 pDNA and p55gag pDNA administered with IL-12 pDNA adjuvant, given by intramuscular (IM) injection with electroporation (EP), in healthy, HIV-uninfected adults.

Participants will be randomly assigned to one of four groups: Group 1 Treatment, Group 1 Control, Group 2 Treatment, or Group 2 Control.

Participants in Group 1 Treatment will receive p24CE1/2 pDNA and IL-12 pDNA at Day 0 and Month 1, then p24CE1/2 pDNA plus p55gag pDNA and IL-12 pDNA at Months 3 and 6. Participants in Group 1 Control will receive placebo (sodium chloride for injection) at Day 0 and Months 1, 3, and 6.

Participants in Group 2 Treatment will receive p55gag pDNA and IL-12 pDNA at Day 0 and Months 1, 3, and 6. Participants in Group 2 Control will receive placebo (sodium chloride for injection) at Day 0 and Months 1, 3, and 6.

Study visits will occur at Day 0, Week 2, and Months 1, 1.25, 1.5, 3, 3.5, 6, 6.25, 6.5, 9, and 12. Visits may include physical examinations and clinical assessments, blood and urine collection, optional stool collection, HIV testing, risk reduction counseling, and interviews/questionnaires. At Month 18, study staff will contact participants for follow-up health monitoring.

  • Good general health as shown by medical history, physical exam, and screening laboratory tests

HIV-Related Criteria:

  • Assessed by the clinic staff as being at "low risk" for HIV infection and committed to maintaining behavior consistent with low risk of HIV exposure through the last required protocol clinic visit.
