Preclinical assessment of the efficacy and specificity of GD2-B7H3 SynNotch CAR-T in metastatic neuroblastoma

Abstract

Antibodies targeting a tumor antigen, GD2, show some efficacy for neuroblastoma but induce severe neuropathic pain and peripheral neuropathy. Here the authors design a gated chimeric antigen receptor (CAR), using GD2 as the gate and another tumor antigen, B7H3, as the target, to find this GD2-B7H3 CAR capable of suppressing neuroblastoma in mouse models with little adverse effects.
