Epidermal growth factor receptor inhibitors, abbreviated EGFR inhibitors, is a class of drugs that blocks the EGF receptor.

EGFR

  • EGFR (aka. ErbB1 or HER1) is a membranous receptor expressed in epithelial cells.
  • Most of activating mutations in NSCLC are in Exon 18-21 (kinase domain).
  • 45% of the mutations are p.DEL19, approx 40-45% are p.L858R, approx 2% are p.T790M.

Drugs

First generation:

Second generation:

  • Dacomitinib (Vizimpro, Pfizer) - not effective when EGFR T790M mutation present.[3]

Third generation:

  • Osimertinib [4]
