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.
Approximately 50% of nonâsmall cell lung cancer (NSCLC) patients who develop resistance to inhibitors of the epidermal growth factor receptor (EGFR) have acquired a second mutation, T790M, which no current EGFR inhibitors target.Assuming that human tumors and biomarkers behave in a similar way to those in mouse xenografts, these simulations suggest that a dose of 7 to 17 mg of AZD9291 once a day would be efficacious in patients with advanced NSCLC harboring the EGFR-activating and T790M (resistant) mutations,â Dr. Galbraith said.
