ASP2138, a novel 2+1 format, claudin 18.2 x CD3 bispecific antibody, demonstrates selectivity and activity in preclinical cancer models (AACR 2023) - P1 | "ASP2138 exhibited an antitumor effect on human CLDN18.2-expressing gastric cancer in a human PBMC-engrafted NOG mouse model in vivo. In summary, ASP2138 is expected to show a clinical effect through cytotoxicity against CLDN18.2-expressing tumor cells by T-cell activation that results from selective binding to CLDN18.2 and CD3."
