EGFRvIII-targeted CAR T cells have been proposed as a therapeutic option for patients with glioblastoma (GBM), however, clinical responses remain suboptimal. Here the authors engineer anti-EGFRvIII CAR T cells to secrete an optimized SIRPγ-derived CD47 blocker, showing that combining CAR T cell effector functions with enhanced macrophage-mediated tumor cell phagocytosis improves anti-tumor efficacy in preclinical models.
