To test in vivo antitumor activity, mice were engrafted with 1e6 NUP98:KDM5A cells. A single of infusion of 3e6 mB7-H3-CAR T cells demonstrated significant anti-AML activity (p<0.001) when compared to control-CAR T cells, resulting in a survival advantage (p<0.01, N=5/group)....We demonstrate that mB7-H3-CAR T cells have potent anti-AML activity in vitro and in vivo.
