History of auto-immune disease, 11. Organ transplant, 12. Splenectomy, 13. Psychiatric disorder significant enough to hinder participation as assessed by the investigator, 14. Patient who has participated in a clinical research trial in the 30 days preceding the screening visit (V-1M-1). 15.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To assess safety and tolerability of three intramuscular injections of VAC-3S at 16 µg of peptide equivalent/vaccination administered in 4-weeks intervals from D0 to the interim analysis time point (V5M4).;Secondary Objective: • To assess the safety and tolerability of a fourth injection of VAC-3S 20 weeks after the first injection, in the patients who did not reach total anti-3S antibody titers above 500 Arbitrary Units (A.U.). • To assess the immunogenicity of three intramuscular injections of VAC-3S at 16 µg of peptide equivalent/vaccination administered at 4-week intervals from D0 till the interim analysis time point (V5M4). • To assess the immunogenicity of a fourth injection of VAC-3S 20 weeks after the first injection, in the patients who did not rise total anti-3S antibody titers above 500 Arbitrary Units (A.U.) • To assess the time course of markers of progression to AIDS. Markers include CD4/CD8 ratio, CD4+ and CD8+ cell counts and percentages, viral load, phenotypic markers lymphocyte cell differentiation and activation, serum activation markers and HIV DNA bulk from D0 to the final analysis time point.;Primary end point(s): Occurence of any local or systemic adverse event from baseline to the interim analysis time point based on clinical and laboratory monitoring.;Timepoint(s) of evaluation of this end point: At week 16 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - HIV plasma viral load (number of HIV RNA copies/mL) measured by quantitative RT-PCR from baseline to the final analysis time point. - The occurrence of any AE between the interim analysis time point and the final analysis time point. - Anti-3S Ab titers (IgM, IgA or IgG) using ELISA from baseline to the final analysis time point. - CD4+/CD8+ ratio from baseline to the final analysis time point. - CD4+ and CD8+ T cell counts and percentages, and T lymphocyte markers of differentiation and activation using immunophenotyping from D0 to the final analysis time point. - Serum inflammation nmarkers, - HIV DNA bulk;Timepoint(s) of evaluation of this end point: Week 51 | — |
