NCIt definition : An immunoconjugate consisting of anti-carcinoembryonic antigen-related cell adhesion
molecule 5 (CEACAM5) conjugated to a cytotoxic agent, with potential antineoplastic
activity. Upon administration of tusamitamab ravtansine the antibody moiety targets
CEACAM5 on tumor cells. Upon antibody/antigen binding and internalization, the immunoconjugate
releases the cytotoxic agent, which results in tumor cell death. CEACAM5, a member
of the CEA family of proteins that plays a key role in cell migration, cell invasion,
and cell adhesion, is overexpressed by a variety of cancer cell types.;
