Hope and Disappointment: Covalent Inhibitors to Overcome Drug Resistance in Non-Small Cell Lung Cancer

Abstract

In the last five years, the detailed understanding of how to overcome T790M drug resistance in non-small cell lung cancer (NSCLC) has culminated in the development of a third-generation of covalent EGFR inhibitors with excellent clinical outcomes. However, the emergence of a newly discovered acquired drug resistance challenges the concept of small molecule targeted cancer therapy in NSCLC.
