Institutions JCO OP DAiS, ASCO eLearning ASCO Author Services These include erlotinib and gefitinib and it has been demonstrated that a group of mutations centered at the ATP-binding pocket of EGFR confer sensitivity to these agents by enhancing … Rather, there are many different types of EGFR mutations, which vary both in the type of mutation (as described above) and in the location of the mutation in a gene. In the case of T790M, mutation at the so-called ‘gatekeeper’ amino acid 79013 renders EGFR refractory to EGFR-TKIs via steric hindrance and increased ATP affinity.14,15 Other secondary mutations in EGFR that have been linked to acquired resistance to EGFR-TKIs include D761Y and T854A (gefitinib and erlotinib only) and L747S (gefitinib only).16–18, Amplification of HER2 and MET have been implicated in the acquired resistance to EGFR-TKIs (gefitinib and erlotinib only) in patients with EGFRm NSCLC.19,20 It is understood that the amplification of these genes leads to the upregulation of parallel signalling pathways, thereby negating the inhibition by EGFR-TKIs.21, Mutations in downstream effector molecules of the EGFR signalling pathway (e.g. AZD9291, an irreversible EGFR TKI, overcomes T790M-mediated resistance to EGFR inhibitors in lung cancer.
