Givastomig

Givastomig (ABL111, TJ033721) is a bispecific antibody (BsAb) inhibitor. Givastomig can specifically binds to Claudin18.2 (CLDN 18.2) on the surface of cancer cells and 4-1BB (CD137, TNFRSF9) on the surface of activated T cells and natural killer (NK) cells. Givastomig is engineered to contain a single Fc-domain mutation (asparagine to alanine) to eliminate Fc-effector function. Givastomig-bound cell lines expressing a range of CLDN18.2 levels with high affinity and induced 4-1BB activation only in the context of CLDN18.2 binding. Givastomig can be used for the study of colon carcinoma[1].
