Effectiveness of and Immune Response to HIV Vaccination Followed by Treatment Interruption in HIV Infected Patients

Study:

A Phase II Double-Blind, Randomized, Placebo-Controlled Study to Evaluate the Antiretroviral Effect of Immunization With the MRK Ad5 HIV-1 Gag Vaccine in HIV-1 Infected Individuals Who Interrupt Antiretroviral Therapy

Rationale:

n/a

Purpose:

HIV vaccines may help the immune systems of HIV infected patients better control the virus. The goal of this study is to determine whether patients on anti-HIV medications can stop taking those medications if they receive an HIV vaccine. While taking anti-HIV medications, participants will receive either an HIV vaccine or a placebo. Participants will then stop taking their anti-HIV medications and the study will compare the viral loads of participants who received the vaccine with the viral loads of participants who received the placebo. Primary study hypotheses: 1)The Week 12 and Week 16 post-ART interruption geometric mean HIV-1 RNA levels will be lower among participants who had received MRK Ad5 vaccine prior to ART interruption than among participants who received placebo; 2) the time averaged area under the curve of the log10 HIV-1 RNA copies/ml versus day function in the 16 week post-ART interruption step will be lower among participants who received the MRK Ad5 vaccine prior to ART interruption than among participants who receive placebo.
