Untreated HIV-1 infection is characterized by progressive immune dysfunction and the development of opportunistic infections and AIDS-associated malignancies. Highly active antiretroviral therapy (HAART) has been successful in suppressing HIV replication and restoring partial immune function. However, HIV-specific immunity remains poor, as evidenced by rapid rebound of HIV-1 RNA following HAART withdrawal. Studies of individuals with acute HIV-1 infection, as well as those who are long-term nonprogressors, have suggested that robust HIV-specific immune responses are associated with control of HIV-1 viremia. Dendritic cells (DCs) are potent antigen presenting cells that may increase HIV-specific immune responses. This protocol will evaluate the use of DCs to help control HIV infection.
Patients will be randomized to receive either intravenous or subcutaneous administration of HIV antigen expressing DCs. Each subject will receive two administrations of mature DCs given 3 weeks apart. Subjects will be followed weekly for 8 weeks, then at Weeks 12, 16, 24, 36, and 48. Two doses of DCs will be evaluated (low dose: 1-3 million cells; high dose: 5-10 million cells) for safety and immune system response.
