EGFR and HER2 inhibitors act on two closely related receptor tyrosine kinases of the ErbB family. The epidermal growth factor receptor (EGFR, ErbB1) and human epidermal growth factor receptor 2 (HER2, ErbB2) form dimers with each other and with ErbB3 and ErbB4. Receptor activation engages the mitogen-activated protein kinase (MAPK) and phosphoinositide 3-kinase (PI3K) pathways that control cell growth. Activating EGFR mutations in non-small-cell lung cancer have made the receptor a central model in kinase inhibitor research. Gefitinib and erlotinib are reversible EGFR inhibitors, and lapatinib inhibits both EGFR and HER2. Osimertinib binds covalently to EGFR carrying the T790M resistance mutation, and neratinib irreversibly inhibits HER2 and EGFR.
