Bispecific and split CAR T cells targeting CD13 and TIM3 eradicate acute myeloid leukemia

Chimeric antigen receptor (CAR) T cells have radically improved the treatment of B cell-derived malignancies by targeting CD19. The success has not yet expanded to treat acute myeloid leukemia (AML). We developed a Sequentially Tumor-Selected Antibody and Antigen Retrieval (STAR) system to rapidly isolate multiple nanobodies (Nbs) that preferentially bind AML cells and empower CAR T cells with anti-AML efficacy. STAR-isolated Nb157 specifically...
