Tri-virus/GD2-specific Allogeneic Cytotoxic T-lymphocytes

**Semantic type:** Cell|Pharmacologic Substance

**Definition:** Allogeneic tri-viral specific, Epstein-Barr virus (EBV), cytomegalovirus (CMV) and adenovirus (Ad), cytotoxic T-lymphocytes (tV-CTLs) expressing a chimeric antigen receptor (CAR) specific for disialoganglioside GD2 with potential antineoplastic activity. Tri-virus/GD2-specific allogeneic CTLs are produced by transducing tV-CTLs with a GD2-specific CAR retroviral vector. Upon administration, after an allogeneic hematopoietic stem cell transplant, these CTLs may be selective towards EBV, CMV, and Ad-infected cells and GD2-expressing tumor cells. The human glycosphingolipid GD2 is a tumor associated antigen overexpressed on the surface of all tumors of neuroectodermal origin.
