cd3 antibody and its pharmaceutical use. the present invention relates to a cd3 antibody and its pharmaceutical use. specifically, the present disclosure relates to the formation of an antibody with multispecificity using the cd3 antibody and other target binding molecules. the multispecific antibody can simultaneously bind to cd3 and another tumor associated antigen, and bind and activate cd3-positive T cells, while binding to cells that express tumor associated antigens, thus promoting T cells that specifically kill tumor cells that express tumor associated antigens. in addition, the present description also provides a preparation and application of a multispecific antibody. |
