Evaluating the safety and effectiveness of a new HIV vaccine.
Treatment Category: Treatment Experienced
A5369 is a study that will evaluate the safety and effectiveness of a new vaccine in HIV- infected persons. This vaccine, which is called a therapeutic or treatment vaccine, is not meant to prevent HIV infection but rather to improve how the immune system responds to HIV infection.
Why is this study being done?
- The study will look at whether an anti-HIV vaccine is safe and effective in people infected with HIV.
- The study will look at whether or not the anti-HIV vaccine improves immune responses.
Who can join?
- HIV-1-infected individuals between the ages of 18 and 65 years
- Current CD4 cell count greater than 500, and never less than 350
- On HIV treatment for at least 2 years with undetectable HIV viral loads for at least 3 years
- No active Hepatitis B or C, no diabetes
What do I need to do in the study?
Participants will be randomly assigned (assigned by chance) to one of these groups:
Arm 1: p24CE1/2 pDNA vaccine (at weeks 0 and 4) followed by p24CE1/2 + full-length p55gag pDNA vaccine (at weeks 12 and 24)
Arm 2: Full-length p55gag pDNA vaccine (at weeks 0, 4, 12, and 24)
Arm 3: Placebo (at weeks 0, 4, 12, and 24)
The vaccines/placebo will be administered by intramuscular injection/electroporation.
Participants must be taking and planning to continue their current anti-HIV medications.
All participants will be followed in the study for up to 48 weeks.
