anti-CD19/CD3 bispecific antibody CN201

A bispecific antibody and a T-cell engager targeting both the tumor-associated antigen (TAA) CD19, and the T-cell surface antigen CD3, with potential immunostimulating and antineoplastic activities. Upon administration, anti-CD19/CD3 bispecific antibody CN201 binds to both the CD3 antigen on T cells and the CD19 antigen expressed on tumor cells. This results in the cross-linking of T cells and tumor cells, and induces a cytotoxic T-lymphocyte (CTL) response against CD19-expressing tumor cells. CD19 antigen is a B-cell specific cell surface antigen overexpressed in B-cell lineage malignancies.
