A Study of the Safety and Effectiveness of an HIV Vaccine for HIV-Positive Patients Receiving Anti-HIV Drugs for at Least 2 Years
The purpose of this study is to see if 2 study vaccines, ALVAC-HIV (vCP1452) and gp160 MN/LAI-2, are safe and effective in boosting the body's attacks on HIV in HIV-positive patients.
HIV-infected patients who have been treated with anti-HIV drugs for a long time may have weakened immune responses. One way to strengthen these responses may be to have a safe and effective vaccine, which will boost immune responses that are specific to HIV.
|HIV Infections||Biological: ALVAC(2)120(B,MN)GNP (vCP1452) Biological: gp160 MN/LAI-2||Phase 1|
|Study Design:||Masking: None (Open Label)
Primary Purpose: Treatment
|Official Title:||A Phase I/II Safety and Immunogenicity Evaluation of a Prime/Boost Vaccine Using ALVAC-HIV (vCP 1452) With Recombinant gp160 LAI/MN-2 in HIV-Infected Subjects Treated With Antiretroviral Therapy for a Minimum of 2 Years|
|Study Completion Date:||June 2007|
HIV-infected patients treated with antiretroviral therapy for prolonged periods of time may show decreased levels of HIV-specific immune responses. In these patients, a prime-boost vaccine strategy may induce both humoral and cell-mediated immunity. The hypothesis of this study is that the vaccine strategy selected will be both safe and immunogenic in the patient population being tested.
Patients continue antiretroviral medications throughout the course of this study. All patients receive intramuscular injections of ALVAC-HIV (vCP 1452) and recombinant soluble gp160 MN/LAI-2 on Days 0, 30, 90, and 180. Patients are monitored for safety 30 minutes after each immunization and by telephone contact within 72 hours of each vaccination. In addition, each patient records adverse events in a diary. Patients have regular physical exams, pregnancy tests, and blood drawn for virologic and immunologic assessments. The induction of HIV-specific responses will be measured.
