Considering the array of functions sequentially exerted by the regulatory and the structural gene products in supporting the setting of a primary HIV infection, it is expected that vaccines combining early and late viral products (combined vaccines) should be superior to the single antigens approaches since they target multiple viral proteins which are necessary at different key steps of the virus life cycle, including cell-to-cell virus transmission and systemic virus propagation. A combined vaccine strategy based on the early regulatory protein Tat in association with the late structural protein Env modified to increase its immunogenicity (delta-V2Env) has been evaluated in pre-clinical studies in both small animals and monkeys. The results of these studies indicated that the combination of Tat with delta-V2Env is superior in inducing specific immune responses against both Tat and delta-V2Env antigens and in protecting or containing virus replication more efficiently than vaccination with the single antigens alone, confirming that these proteins represent optimal co-antigens for a combined vaccine strategy.\n\nThis study was a multicentric, open label, randomized phase I trial, directed to qualify the safety and the immunogenicity of the vaccine based on the association of HIV-1 biologically active Tat and oligomeric ΔV2 Env proteins in healthy, immunologically competent adult volunteers, compared to the single compounds. Tat and delta-V2 Env proteins either in association or as single compounds were administered by a prime-boost regimen, consisting of 3 intradermal priming doses followed by 2 intramuscular boosting injections. Of note, phase I trials have already been successfully conducted with the 2 single components, at the doses proposed in this trial, in healthy individuals.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
