PROBLEM TO BE SOLVED: To provide a multispecific antigen-binding molecule and a cytotoxic induction therapeutic agent. SOLUTION: Excellent cytotoxic activity and high safety are maintained, including a domain containing an antibody variable region having glypican 3-binding activity and a domain containing an antibody variable region having T cell receptor complex binding activity. In addition, since it is a new multispecific antigen-binding molecule and exhibits strong cytotoxicity to cells and tissues expressing glypican 3, a new pharmaceutical composition for treating or preventing various cancers has been developed. It is possible to manufacture.
