A Phase I/II Double-Blind Controlled Trial to Determine the Safety and Immunogenicity of HIV-1 MN rgp160 Immuno AG Vaccine Therapy in HIV-Infected Individuals With Greater Than or Equal to 500/mm3 CD4+ T Cells and 200-400/mm3 CD4+ T Cells

Summary

To evaluate the safety and immunogenicity of HIV-1 MN rgp160 (Immuno-AG) in HIV-infected patients. To evaluate the immunogenicity of HIV-1 MN rgp160 immunogen by lymphocyte proliferation, specific antibody responses, and DTH reaction. To describe the durability of the immunogen in patients who respond to the first 7 injections when they are boosted every 8 weeks for an additional 6-12 months \[AS PER AMENDMENT 11/12/96: stratum 1 patients only\]. To describe the ability of the immunogen to induce a response after an additional 6-12 months of injections among patients who did not respond to the first 7 injections \[AS PER AMENDMENT 11/12/96: stratum 1 patients only\]. HIV-specific cellular immune responses appear to play an important role in HIV disease progression since both T helper and cytotoxic function against HIV decrease with disease progression.
