Patients receiving fully suppressive antiretroviral therapy are randomized to add either Remune or an Incomplete Freund's Adjuvant (IFA) control. Vaccinations are administered on Day 1, Week 12, and Week 24. Blood samples are collected at Day 1 and Weeks 4, 12, 16, 24, and 28. Clinical assessment includes lymphocyte proliferative response, cytotoxic T lymphocyte (CTL) memory cell activity, chemokine and cytokine measurements, CD4 count, and viral load. Delayed-type hypersensitivity (DTH) skin tests are performed at Day 1 and Week 28. HIV-1 specific immunogenicity is coordinated with the response to antiretroviral therapy in patients.
