Osimertinib for Japanese patients with T790M-positive advanced non-small-cell lung cancer: A pooled subgroup analysis.

ABSTRACT: Epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) are the standard of care for non-small-cell lung cancer (NSCLC) patients harboring EGFR mutations. However, almost all patients develop resistance after approximately 1 y of treatment, with >50% of cases due to the T790M secondary mutation of the EGFR gene. A large global Phase III study (AURA3) demonstrated that osimertinib significantly prolonged progression-free survival (PFS) over platinum-doublet chemotherapy in patients with T790M-positive NSCLC who had progressed on previous EGFR-TKI therapy. However, it is not clear whether efficacy or safety of osimertinib in Japanese patients is similar to the overall population. We report a pre-planned subgroup analysis of pooled Phase II data from the AURA Extension and A
