NCT00121121

  Purpose

Intramuscular (IM) administration of HIV lipopeptide vaccines have been shown to be able to induce HIV-1-specific T cell-mediated immune responses. The objective of this trial was to evaluate the safety and immunogenicity of LIPO-4 vaccine (HIV lipopeptides including 4 peptides from Gag, Pol, RT and Nef HIV-1 proteins, each peptide linked to TT) intradermally (ID) compared to IM administration.

Primary Outcome Measures:
  • Clinical and biological safety (over or equal to degree two of a adverse event grading scale) of LIPO-4 by ID and IM routes during the study

Secondary Outcome Measures:
  • Comparaison of CD4 positive cells responses using
  • lymphoprolifération test and CD8 positive cells responses using the capacity of these cells to synthesize IFN following stimulation with peptides of interest (ELISPOT IFN test) following IM or ID administration at weeks 2, 6, 14, 24, and 48

Estimated Enrollment: 70

Estimated Study Completion Date: December 2005
Detailed Description:

Dose-sparing strategies that use intradermal (ID) delivery of vaccines may be one approach for improving a vaccines immunogenicity and reducing the cost of vaccines.

In this study, 68 HIV-negative healthy adult volunteers, 21-55 years old, all belonging to the "Volunteers for a Vaccine" network set up by ANRS, were randomized to receive at weeks 0, 4, and 12, either 3 IM doses of 0.5 ml of LIPO-4 containing 500 µg of each peptide (n= 35 volunteers), or 3 ID doses of 0.1 ml, containing 100 µg of each peptide (n=33 volunteers). Total follow-up was 48 weeks. Safety was assessed clinically and by laboratory tests. Participants were given diary cards to record adverse events. HIV-1 immune responses were assessed by ELISPOT and lymphoproliferative assay at weeks 0, 2, 6, 14, 24, and 48
