Here, we discuss effects of the GB tumor microenvironment on NK-cell functionality, summarize early treatment attempts with <i>ex vivo</i> activated NK cells, and describe relevant CAR target antigens validated with CAR-T cells.
A first-in man exploratory study evaluating EGFRvIII-specific CAR T cells for patients with newly diagnosed glioblastoma demonstrated overall safety of CAR T cell therapy and effective target recognition.
These results suggested that tumor-selective, bitargeted anti-EGFR/EGFRvIII CAR T cells may be a promising modality for the treatment of patients with EGFR/EGFRvIII-overexpressing glioblastoma.<i></i>.
We transduced human NK cell lines NK-92 and NKL, and primary NK cells with a lentiviral construct harboring a second generation CAR targeting both wtEGFR and EGFRvIII and evaluated the anti-GB efficacy of EGFR-CAR-modified NK cells.
