We have investigated the in-vivo safety, efficacy and persistence of autologous Epstein Barr Virus (EBV)-specific cytotoxic T lymphocytes (CTL) for the treatment solid organ transplant (SOT) recipients at high-risk for EBV-associated post-transplant lymphoproliferative disease (PTLD). EBV-CTL generated from 35 patients expanded with normal kinetics, contained both CD8 and CD4 lymphocytes and produced significant specific killing of autologous EBV-transformed B lymphoblastoid cell lines (LCL). Twelve SOT recipients at high risk for PTLD, or with active disease, received autologous CTL infusions without toxicity. Real-time PCR monitoring of EBV-DNA showed a transient increase in plasma EBV-DNA suggestive of lysis of EBV-infected cells, although there was no consistent decrease in virus load in peripheral blood mononuclear cells. Interferon-g Elispot assay and tetramer analysis showed an increase in the frequency of EBV-responsive T cells, which returned to pre-infusion levels after 2-6 months. None of the treated patients developed PTLD. One patient with liver PTLD showed a complete response, and one with ocular disease has had a partial response stable for over one year. These data are consistent with an expansion and persistence of adoptively transferred EBV-CTL, that is limited in the presence of continued immunosuppression, but that nonetheless produces clinically useful anti-viral activity.
