Safety of and Immune System Response to an HIV Vaccine (EP HIV-1090) in HIV Infected Patients
A Single Center Phase I Safety and Immunogenicity Study of Epimmune HIV-1 CTL Epitope-Based DNA Vaccine (EP HIV-1090) for Immunotherapy of HIV-1 Infected Individuals Receiving Highly Active Antiretroviral Therapy (HAART)
Studieoversikt
Detaljert beskrivelse
Significant data support the hypothesis that HIV-specific cytotoxic T lymphocyte (CTL) responses contribute to the control and potential clearance of the virus. Vaccines designed specifically to induce CTL responses are likely to be well suited for treatment of HIV infection. The conceptual basis of the EP HIV-1090 vaccine is the use of highly defined CTL epitopes as the vaccine immunogen. The vaccine is formulated with a water-soluble polymer that stabilizes and protects the DNA and facilitates uptake by cells. Preclinical studies have shown that the vaccine induces strong CTL responses in animal models. This study will evaluate the safety and tolerability of the vaccine and the immune response to the vaccine in HIV-1-infected individuals who are being treated with highly active antiretroviral therapy (HAART) and have a CD4 count of 350 cells/mm3 or more and fully suppressed viral replication on stable HAART.
Each patient will receive a total of four immunizations to be given at Day 0 and at Weeks 4, 8, and 16. Participants will be randomly assigned to receive either vaccine or placebo. Ten patients will be assigned to each dose group; eight will receive active vaccine and two will receive placebo. The injections will be delivered intramuscularly into the deltoid muscle. In addition to undergoing standard safety exams, patients will have blood drawn for use in evaluating the immunogenicity of the vaccine. The treatment duration will be 16 weeks and patient will be followed for safety and immune responses for an additional 24 weeks after they complete vaccination; the total study is estimated to take 18 months.
