HIV I Infection
Conditions
Brief summary
Current management of HIV infection includes anti-retroviral therapy (ART). ART cannot cure the infection, making it a life-long treatment that requires sustained patient compliance and imposes significant individual and societal financial burdens on healthcare services. Furthermore, ART side effects often require medication that increases the inconveniences and financial burdens of HIV management. Of further concern is the emergence of viruses resistant to ART that can result in treatment failure. ART-free periods could provide substantial benefit. Vacc-4x is a peptide-based HIV immunotherapy that is proposed for prolongation of ART-free periods. The purpose of this study is to determine whether Vacc-4x immunotherapy can give safe ART-free period.

Interventions
Vacc-4x is a peptide-based HIV immunotherapy administered intradermally. Vacc-4x peptides are reconstituted in sterile water.
Sterile water is used in place of Vacc-4x and in place of Leukine
