Abstract: Disclosed herein is a bi-specific form of a T cell receptor mimic (TCRm) mAb with reactivity to human immune effector cell antigen and a WT1 peptide/HLA-A epitope. This antibody selectively bound to leukemias and solid tumor cells expressing WT1 and HLA-A as well as activated resting human T cells to release interferon-(IFN-?) and to kill the target cancer cells in vitro. Importantly, the antibody mediated autologous T cell proliferation and directed potent cytotoxicity against fresh ovarian cancer cells. Therapeutic activity in vivo of the antibody was demonstrated in NOD SCID SCID Yc*(NSG) mice with three different human cancers expressing WT1/HLA-A2 including disseminated Ph+ acute lymphocytic leukemia (ALL), disseminated acute myeloid leukemia, and peritoneal mesothelioma. In both of the leukemia xenograft models, mice that received the antibody and T cells also showed longer survival and delayed limb paralysis.

Abstract: The present disclosure relates to an anti-WT-1/HLA/A2 antibody with enhanced antibody dependent cell-mediated cytotoxicity (ADCC) function due to altered Fc glycosylation. The antibody, which has reduced fucose and/or galactose, was compared to its normally glycosylated counterpart in binding assays, in vitro ADCC assays, and mesothelioma and leukemia therapeutic models and pharmacokinetic studies in mice. The antibody with normal glycosylation mediated ADCC against hematopoietic and solid tumor cells at concentrations below 1 ?g/ml, but the reduced fucosylated antibody was about 5-10 fold more potent in vitro against multiple cancer cell lines, was more potent in vivo against JMN mesothelioma, and effective against SET2 AML and fresh ALL xenografts. ESKM had a shortened half-life (4.9 vs 6.5 days), but an identical biodistribution pattern in C57BL6/J mice. At therapeutic doses of ESKM, there was no difference in half-life or biodistribution in HLA-A2.1+ transgenic mice compared to the parent strain.
