Epstein Barr virus-specific cytotoxic T lymphocytes expressing the anti-CD30ζ artificial chimeric T-cell receptor for immunotherapy of Hodgkin disease

Academic Article


  • Adoptive transfer of Epstein Barr virus (EBV)-specific cytotoxic T-lymphocytes (EBV-CTLs) has shown that these cells persist in patients with EBV+ Hodgkin lymphoma (HD) to produce complete tumor responses. Treatment failure, however, occurs if a subpopulation of malignant cells in the tumor lacks or loses expression of EBV antigens. We have therefore determined whether we could prepare EBV-CTLs that retained the antitumor activity conferred by their native receptor while expressing a chimeric antigen receptor (CAR) specific for CD30, a molecule highly and consistently expressed on malignant Hodgkin Reed-Sternberg cells. We made a CD30CAR and were able to express it on 26% (± 11%) and 22% (± 5%) of EBV-CTLs generated from healthy donors and HD patients, respectively. These CD30CAR+ CTLs killed both autologous EBV+ cells through their native receptor and EBV -/ CD30+ targets through their major histocompatibility complex (MHC)-unrestricted CAR. A subpopulation of activated T cells also express CD30, but the CD30CAR+ CTLs did not impair cellular immune responses, probably because normal T cells express lower levels of the target antigen. In a xenograft model, CD30CAR+ EBV-CTLs could be costimulated by EBV-infected cells and produce antitumor effects even against EBV-/CD30+ tumors. EBV-CTLs expressing both a native and a chimeric antigen receptor may therefore have added value for treatment of HD. © 2007 by The American Society of Hematology.
