Interventions

  • CMV/HIV-CAR T Cells — BIOLOGICAL
    Eligible participants will temporarily interrupt their ART regimen for 4 days prior to leukapheresis to prevent residual cell drug levels that could inhibit lentiviral transduction of the T cells during CAR T cewll manufacturing. Participants will resume their ART regimen immediately after leukapheresis. Once the final cell product is released, participants will receive a single intravenous (IV)infusion of autologous CMV/HIV-CAT T cells (defined as Day 0). Up to three doses of CMV/HIV-CAR T cewlls may be explored.

Study Details

Human immunodeficiency virus type 1 (HIV-1) causes a persistent infection that ultimately leads to acquired immunodeficiency syndrome (AIDS). Treatment of HIV-1 infection with combination anti-retroviral therapy (ART) suppresses HIV-1 replication to undetectable viral levels and saves lives. Nevertheless, ART cannot eradicate latent cellular reservoirs of the virus, and HIV-1 infection remains a life-long battle. Adoptive cellular immunotherapy using chimeric antigen receptor (CAR) engineered T cells directed against HIV-1 envelope subunit protein gp120 (HIVCAR T cells) may provide a safe and effective way to eliminate HIV-infected cells. However, the number of HIV-infected cells is low in participants under ART, and CAR T cells disappear if they are not stimulated by their target antigens. Interestingly, about 95% of HIV-1-infected individuals are CMV-seropositive and CMV-specific T cells have been shown to persist. To overcome the CAR T cells low persistence issue, we propose to make HIV-CAR T cells using autologous cytomegalovirus (CMV)-specific T cells, which can be stimulated by endogenous CMV in vivo. The overall hypothesis of this first-in-human Phase 1, open-label, single-arm study is that endogenous immune signals to CMV-specific T cells can maintain the presence of autologous bispecific CMV/HIV-CAR T cells in healthy people living with HIV-1 (PLWH), and achieve long-term remission in the presence of ART.
