Interventions

PART 1. GROUP 1 Type of group
This group will be divided into 2 subgroups that will receive different treatment. 10 individuals will receive the Multiepitopic Recombinant Protein Vaccine EP-1043, which contains 0.05 mg of recombinant baculovirus expression protein adsorbed on Alhydrogel®, in 1 ml, IM in the same deltoid muscle, once in months 0, 1, 3 and 6. 2 individuals will receive the Multiepitopic Vaccine of Recombinant Protein EP-1043 Placebo, in 1 ml, IM in the same deltoid muscle, once in months 0, 1, 3 and 6.
This group will be divided into 2 subgroups that will receive different treatments. 30 individuals will receive the EP-DNA Multiepitopic HIV-1090 Vaccine, which contains 4 mg of DNA Plasmid in phosphate buffer saline containing 3.4% polyvinylpyrrolidone, in 2 ml, IM, in the vastus externus muscle, which can be injected into different thighs at each opportunity + Multiepitopic Recombinant Protein EP-1043 vaccine, which contains 0.2 mg of recombinant baculovirus expression protein adsorbed on A

Design outcomes

Primary

MeasureTime frame
Outcome name:Clinical evaluation to evaluate: 1) Signs and symptoms of local reactogenicity: At the site of injection, pain, tenderness, erythema, induration / swelling / edema. 2) Signs and symptoms of systemic reactogenicity: Body temperature, malaise and / or fatigue, myalgia, headache, chills, arthralgia, nausea, vomiting. 3) Safety measures in the laboratory: Urine test, hematology panels and serum chemistry. 4) Adverse events and severe adverse events: Their evaluation and classification will be based on the Severity Classification Table of Adverse Events Adults and Pediatrics of the Division of AIDS Version 1.0. Measure:Safety of treatment: 1) Signs and symptoms of local reactogenicity. 2) Signs and symptoms of systemic reactogenicity. 3) Safety measures in the laboratory. 4) Adverse events and severe adverse events. Timepoints:1) Signs and symptoms of local and systemic reactogenicity: Up to 3 days after the application of each vaccine. 2) Safety measures in the laboratory: Days 14, 42, 98, 182, 273 and 364. 4) Adverse events and severe adverse events: Days 98, 182, 273 and 364.

Secondary

MeasureTime frame
Outcome name:The ability of the vaccine to induce CD8 + and CD4 + T cell responses to specific epitopes will be evaluated by the following techniques: 1) ELISpot test for interferon gamma: Cryopreserved peripheral blood mononuclear cells stimulated during the night with synthetic peptide groups that group the proteins encoded by the recombinant DNA fragments of the vaccine will be used. The responses will be reported as number of staining cells (SFC) per 10-6 cells / good recognition of any specific peptide group. 2) Intracellular cytokine staining (ICS): Flow cytometry will be used to examine the responses of CD4 + and CD8 + T cells, after stimulation with synthetic HIV peptides that group the proteins encoded by the recombinant DNA fragments of the vaccine. Responses will be reported as a percentage of CD4 + or CD8 + T cells that recognize any specific peptide group. Measure:Immunogenicity: Specific cellular response to HIV. Timepoints:Two weeks after the visit of the fourth vaccine (day 168). ; Outcome name:All negative experiences or problems that the participant has experienced during their participation in this study will be evaluated. The following social impact will be monitored during the course of the study; social, travel, work, school, health care, life insurance, health insurance, housing, military service and any additional impact identified by a participant. Measure:Social impact. Timepoints:Days 84 and 68.
