Mechanism of action

From the NCI Drug Dictionary: A bispecific monoclonal antibody, with potential antineoplastic activity. Glofitamab contains two antigen-recognition sites: one for human CD3, a T cell surface antigen, and one for human CD20, a tumor-associated antigen (TAA) that is exclusively expressed on B-cells during most stages of B-cell development and is often overexpressed in B-cell malignancies. Upon administration, glofitamab binds to both T-cells and CD20-expressing B-lineage tumor cells. The resulting cross-linkage may trigger a potent cytotoxic T-lymphocyte (CTL) response against the CD20-expressing tumor B-cells.
