NCT00472719

Brief Summary

The purpose of this study is to determine the safety of and immune response to an experimental DNA HIV vaccine followed by boosting with either an experimental adenoviral vector HIV vaccine of serotype 5 or 35 in HIV uninfected adults. This study will also determine the safety of and immune response to an adenoviral vector HIV vaccine of serotype 5 followed by a booster of an adenoviral vector of serotype 35, or vice versa, in HIV uninfected adults.

Outcome Measures

Primary Outcomes (4)

  • Safety and tolerability of HIV-1 recombinant Clade A env DNA, rAd5, and rAd35 vaccines in participants with pre-existing immunity to Ad5

    at 9 to 12 months

  • Magnitude and frequency of immune responses between the adenoviral vaccines following DNA prime, assessed by enzyme-linked immunospot (ELISpot) responses, intracellular cytokine staining (ICS) T-cell responses, and HIV-1 antibody assays

    at 4 weeks following fourth vaccination

  • Immunogenicity of recombinant HIV-1 Clade A env rAd35 vaccine following a recombinant rAd5 prime, assessed by ELISpot responses, ICS T-cell responses, and HIV-1 antibody assays

    at 4 weeks following the second vaccination

  • Immunogenicity of recombinant HIV-1 Clade A env rAd5 vaccine following a recombinant rAd35, assessed by ELISpot responses, ICS T-cell responses, and HIV-1 antibody assays

    at 4 weeks following the second vaccination

Secondary Outcomes (3)

  • Rank of HIV-1 rAd5/rAd35, rAd35/rAd5, DNA/rAd5, and DNA/rAd35 regimens based on ELISpot responses, ICS T-cell responses, and HIV-1 antibody assays

    at 4 weeks after second vaccination for Groups 1 and 2, and at 4 weeks after fourth vaccination for Groups 3 and 4

  • Immunogenicity of HIV-1 rAd35 vaccine given as a prime assessed by ELISpot responses, ICS T-cell responses, and HIV-1 antibody assays

    at 4 weeks following first vaccination

  • Immunogenicity of HIV-1 rAd5 vaccine given as a prime, assessed by ELISpot responses, ICS T-cell responses, and HIV-1 antibody assays

    at 4 weeks following first vaccination
