PHPC-02 is a phase II, randomized, placebo-controlled trial designed to investigate whether therapeutic immunization during highly active antiretroviral therapy (HAART) induces elevations of HIV-specific T cell precursors with high proliferative capacity (PHPC) in HIV-1-infected individuals, and whether the quantity of PHPC correlates with the viral load set point following analytical treatment interruption (ATI). Subjects will be randomized to receive either DermaVir Patch (8 subjects per cohort) or DermaVir Patch Placebo (8 subjects per cohort) every four weeks for three applications while receiving maximally suppressive HAART. HAART will be discontinued at Week 9 for an ATI period of 20 weeks.
16 subjects on maximally suppressive HAART were randomized to receive three doses of either DermaVir or Placebo immunotherapy.
Subjects receive three DermaVir/Placebo treatments over eight weeks (Weeks 0, 4 and 8) while receiving HAART. HAART is discontinued for a 20 week ATI.
Resumption of HAART during ATI is subjects experience:

| DermaVir | Biological | DermaVir is a synthetic nanomedicine. The active pharmaceutical ingredient is a single plasmid DNA expressing 15 HIV proteins that assemble to HIV-like particles. DermaVir is topically administered with DermaPrep medical device to target the nanomedicine to Langerhans cells of the skin.These Langerhans cells migrate to the lymph node to induce cytotoxic T cells that can kill HIV-infected cells |
