Osimertinib: A Review in Completely Resected, Early-Stage, EGFR Mutation-Positive NSCLC

AbstractOsimertinib (TAGRISSO®) is an orally administered, third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor that is approved for the adjuvant treatment of adults with completely resected, stage IB –IIIA,EGFR sensitizing mutation (exon 19 deletion or exon 21 [L858R] substitution)-positive non-small cell lung cancer (NSCLC). In the pivotal ADAURA trial in adults with completely resected, early-stage,EGFR mutation-positive (EGFRm+) NSCLC, osimertinib adjuvant therapy significantly prolonged disease-free survival (DFS) compared with placebo in the overall population of patients with stage IB –IIIA disease, as well as in the primary population of patients with stage II–IIIA disease. A DFS benefit of osimertinib was seen irrespective of whether or not patients received prior adjuvant chemotherapy. Overall survival (OS) data were very immature at the time of the analysis of DFS, and mo re mature OS data are awaited with interest. Osimertinib adjuvant therapy did not adversely affect health-related quality of life and was generally well tolerated, with a manageable safety profile and no new safety signals identified. Based on the available evidence, osimertinib is thus an appropria te targeted option for the adjuvant treatment of adults with completely resected, stage IB–IIIA,EGFRm+ NSCLC.
