Cytotoxicity-inducing therapeutic agent

摘要

A novel multispecific antigen-binding molecule, which comprises a domain containing an antibody variable region having an activity of binding to glypican 3 and a domain containing an antibody variable region having an activity to bind to a T cell receptor complex and retains excellent cytotoxic activity and high safety, was found. The molecule according to the present invention exhibits potent cytotoxic activity on cells and tissues expressing glypican 3 and, therefore, enables the production of new pharmaceutical compositions for treating or preventing various kinds of cancers.
