The present disclosure provides a pharmaceutical composition that is to be used in combination with administration of an antigen-binding molecule capable of binding to a target antigen, and that contains a cell which expresses an antibody having ADCC activity, a T cell-redirecting antibody, or a chimera receptor. The antigen-binding molecule as a primary molecule contains a linker which is to be cleaved by a protease. The antigen-binding molecule in which the linker is cleaved has the ability to bind to the target antigen. A variable domain of the antibody having ADCC activity or the T cell-redirecting antibody, and an extracellular binding domain of the chimera receptor, bind to a cell that expresses the target antigen, through binding to the antigen-binding molecule, in which the linker is cleaved, obtained after cleavage of the cleaved linker. |
