About
The purpose of this study is to determine the safety of two recombinant HIV vaccines in HIV infected young adults on stable anti-HIV therapy.
Full description
By helping to control viral replication, HAART has dramatically improved the prognosis for HIV infected individuals. However, because of extensive side effects, some of which may be acute and life-threatening, many patients find it difficult to tolerate a HAART regimen. HAART-associated long-term morbidity or mortality contribute to this difficulty. Administering an HIV therapeutic vaccine might allow HIV infected individuals to delay or interrupt treatment, avoiding the side effects associated with antiretroviral exposure. This study will evaluate the safety of two injections of two recombinant therapeutic vaccines in HIV infected young adults who are currently on stable HAART.
This study will last 72 weeks. All participants will receive two rMVA vaccines (env/gag and tat/rev/nef-RT) at study entry and at Week 4 and two rFPV vaccines (env/gag and tat/rev/nef-RT) at Weeks 8 and 24. Safety will be assessed immediately after each immunization and at 1 hour and 48 hours postimmunization. There will be 16 study visits over 72 weeks. A physical exam, blood collection, and administration of an adherence module will occur at most visits. An electrocardiogram (ECG) will occur at study entry and Weeks 2 and 10. Urine collection will occur at study entry and Weeks 4, 8, and 24.

- Immunomodulatory agents, gamma globulin, or investigational agents within 6 months of study entry
- Systemic steroids, including nonprescription street steroids, within 6 months of study entry
- Documented or suspected serious bacterial infection, metabolic illness, cancer, or immediate life-threatening condition
