Application Notes

This antibody is derived from a mouse parental clone mAb 425 which has demonstrated anti-tumor activity against solid tumors in phase I clinical trials. The binding characterization of this antibody to human EGFR was done using ELISA. This antibody was also found to bind human EGFR with a similar avidity as the parental mouse antibody 425 (PMID: 1798701). The parental mouse antibody 425 in combination with C225 (Cetuximab) reduced growth and survival of EGFR overexpressing MDA-MB-468 breast cancer cells more effectively than either antibody alone. The combination was also reported to effectively inhibited AKT and MAPK phosphorylation in MDA-MB-468 cell (PMID: 18424917). This antibody was used in a phase 1 study to investigate the safety and tolerability and to explore the pharmacokinetic and pharmacodynamic profile in patients with solid tumors that express EGFR (PMID: 14701780). This antibody has been used in various phase I studies alone or in combination with other therapeutic agents to treat patients with various type of cancers (PMID: 16533873; 16622465; 19238629). A study reported that the antitumor effects of matuzumab and cetuximab depend on inhibition of EGFR downstream signaling mediated by Akt or Erk rather than on inhibition of EGFR itself (PMID: 18033688).
