Other names: anti-EGFR, epidermal growth factor receptor inhibitors, erbB-1, HER-1 What are EGFR inhibitors Epidermal growth factor receptor (EGFR, also known as ErbB-1 or HER-1) inhibitors are medicines that bind to certain parts of the EGFR and slow down or stop cell growth. EGFR is a protein that is found on the surface of some cells that causes cells to divide when epidermal growth factor binds to it.
Patients with the most common EGFR mutations (L858R mutation in exon 21 and delE746-A750 deletions in exon 19) typically have good responses to therapy with first-generation reversible EGFR tyrosine kinase inhibitors (TKI), such as erlotinib or gefitinib (3â5).he efficacy of CO-1686 was also examined in the bitransgenic EGFR L858R/T790M; CCSP-rtTA model that mimics T790M-mediated acquired resistance to erlotinib and gefitinib (24). Tumor-bearing animals were randomized and treated with vehicle, 50 mg/kg twice-daily CO-1686, or 20 mg/kg once-daily afatinib.
