 (submitted: November 12, 2009)
  • To assess the safety/tolerability/feasibility of administering autologous CD4-zeta gene modified T cells IV in a setting of highly active antiretroviral therapy (HAART) w & w/o IL-2 at a dose of ~1.2 M IU/m2 SQ daily for 56 days [ Time Frame: Day 56 ]
  • Assess the effect of daily subcutaneous IL-2 on the persistence and trafficking of CD4-zeta gene modified T cells in the circulation and lymphoid (rectal) tissue [ Time Frame: End of study ]
  • Determine the effect of CD4-zeta infusions with and without IL-2 on viral load (plasma HIV-1 RNA, tissue HIV-1 RNA, and frequency of latent replication-competent HIV-1 in PBMC). [ Time Frame: End of Study ]

Descriptive Information
Brief Title  ICMJE CD4-ZETA Gene Modified T Cells With and Without Exogenous Interleukin-2 (IL-2) In HIV Patients
Official Title  ICMJE A Phase I/II Study Of the Safety, Survival, and Trafficking of Autologous CD4-ZETA Gene-Modified T Cells With and Without Extension Interleukin-2 in HIV Infected Patients
Brief Summary The purpose of this study is to find out the safety and activity of an experimental anti-HIV treatment using autologous CD4-zeta gene-changed T cells and/or IL-2 (recombinant interleukin2). The treatments that the investigators are studying try to improve the immune system by changing some of your T cells so they can find and destroy HIV infected cells (HIV is usually able to hide from your T cells). In this study, the investigators are also trying to find out if giving you more IL-2 at the same time as gene changed T cells will help the T cells to live longer or fight HIV better.
