OBJECTIVES: In AURA3 (NCT02151981), osimertinib treatment provided significant clinical benefit compared with platinum-pemetrexed in patients with epidermal growth factor receptor (EGFR) T790M-positive advanced non-small-cell lung cancer (NSCLC), whose tumors had progressed on previous EGFR-tyrosine kinase inhibitor therapy. This retrospective analysis investigated detection rates for T790M, common (exon 19 deletion and L858R), and rare EGFR mutations in tissue samples from the screened population of AURA3. MATERIALS AND METHODS: In AURA3, eligible patients were randomized 2:1 to receive oral osimertinib 80 mg once daily or intravenous platinum-pemetrexed every 3 weeks for up to six cycles. ..View full abstract
