T cells redirected to interleukin-13Rα2 with interleukin-13 mutein--chimeric antigen receptors have anti-glioma activity but also recognize interleukin-13Rα1.

ABSTRACT:

Background aims

Outcomes for patients with glioblastoma remain poor despite aggressive multimodal therapy. Immunotherapy with genetically modified T cells expressing chimeric antigen receptors (CARs) targeting interleukin (IL) 13Rα2, human epidermal growth factor receptor 2, epidermal growth factor variant III or erythropoietin-producing hepatocellular carcinoma A2 has shown promise for the treatment of glioma in preclinical models. On the basis of IL13Rα2 immunotoxins that contain IL13 molecules with one or two amino acid substitutions (IL13 muteins) to confer specificity to IL13Rα2, investigators have constructed CARS with IL13 muteins as antigen-binding domains. Whereas the specificity of IL13 muteins in the context of immunotoxins is well characterized, limited information is a
