Abstract

Abstract Autologous second-generation CD7-directed chimeric antigen receptor T cells, expressing an anti-CD7 protein expression blocker to prevent self-killing fratricide, were infused in 3 pediatric/young adult patients with relapsed/refractory CD7+ acute myeloid leukemia, resulting in measurable residual disease negativity. The safety profile was favorable.
