[A synthetic targeted protein toxin which consists of human transferrin (Tf) conjugated to a diphtheria toxin that contains a point mutation (CRM107). After binding to the transferrin receptor expressed on the tumor cell surface, transferrin-CRM107 is internalized, where the diphtheria toxin moiety exerts its cytotoxic effect intracellularly by inhibiting protein synthesis through ADP-ribosylation of elongation factor.
