The purpose of this study is to see if giving a vaccine (Remune) is effective in HIV-positive patients who are also taking anti-HIV therapy.
Regular treatment of HIV-positive patients with anti-HIV drugs slows the multiplication of the HIV virus in the body. A vaccine called Remune works to stop the virus infection by "boosting" the body's immune cell defense against the HIV virus before the virus enters cells. It also blocks the virus from entering the cells. This study will see whether Remune will improve the immune cell natural defense in patients who are also taking anti-HIV drugs.
|Condition or disease||Intervention/treatment||Phase|
|HIV Infections||Biological: HIV-1 Immunogen||Phase 1|
During primary HIV infection, after an initial burst in viral load, the body mounts an immunologic response to viral antigens. It is thought that this initial immune response plays an important role in determining early and long-term suppression of HIV. However, limited information is available regarding the effect of early antiretroviral therapy on immune responses. Therapeutic approaches such as Remune, which augment cell-mediated immunologic responses, may prove to be beneficial in controlling the progression of HIV infection, especially when used in combination with antiretroviral therapy in early infection. Current antiviral drugs work by inhibiting the infection of new cells yet seem to suppress early cell-mediated immune responses. The question is raised as to whether immune-based therapies such as Remune may counteract the suppressive effects of antiretrovirals and slow the progression of infection.
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.
