Combination Vaccination Before HIV Treatment Interruption
A Pilot Study to Determine the Impact of Therapeutic HIV Vaccination Followed by a Scheduled Interruption of Antiretroviral Therapy on HIV-Specific Immune Function and Virologic Rebound in Patients With Prolonged Viral Suppression

The purpose of this study is to determine if vaccination before a structured treatment interruption (STI) is associated with an improvement in immune function, resulting in a delayed and reduced rebound in the amount of HIV virus in the blood.

Volunteers will be randomly assigned to receive the vaccines or matching placebos before interrupting their antiretroviral therapy at week 24.

Dosage:

Remune(TM) 1 ml i.m.* at weeks 0, 12, and 20; ALVAC 1 ml i.m.* at weeks 8,12, 16, and 20.

* i.m.: injected in a muscle

HIV Infections
Biological: Remune and ALVAC
  • Group 1) Remune™ (1ml i.m.) at weeks 0, 12 and 20 and ALVAC (1 ml i.m.) at weeks 8, 12, 16 and 20);
  • Group 2) Remune™ placebo (1ml i.m.) at weeks 0, 12 and 20 and ALVAC (1 ml i.m.) at weeks 8, 12, 16 and 20; or
  • Group 3) Remune™ placebo (1ml i.m.) at weeks 0, 12 and 20 and ALVAC placebo (1 ml i.m.) at weeks 8, 12, 16 and 20.
