Abstract:Osimertinib is a third-generation epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs). It is currently approved for first-line treatment of patients with advanced non-small cell lung cancer (NSCLC) with EGFR mutation and second-line treatment with T790M mutant NSCLC after the first-generation EGFR-TKIs treatment progresses. Clinical studies have shown that Osimertinib can significantly improve the progression-free survival (PFS) of NSCLC patients, but it also brings serious drug resistance problems. In recent years, studies have found that the first-line application of Osimertinib resistance mechanism mainly depends on the activation of EGFR pathway and bypass signaling pathway; the drug resistance mechanism produced by the second-line and second-line application of Osimertinib depends on the activation of the EGFR pathway, the bypass signaling pathway, and the transformation of the cell phenotype. Osimertinib has different drug resistance mechanisms at different times. In order to provide a theoretical basis for the prevention and treatment of Osimertinib resistance, this article will review the different drug resistance mechanisms and treatment strategies of Osimertinib from the perspective of clinical drug use time.
