A Randomized Phase 2 Study of Gefitinib With or Without Pemetrexed as First-line Treatment in Nonsquamous NSCLC With EGFR Mutation: Final Overall Survival and Biomarker Analysis

Abstract excerpt

INTRODUCTION: Clinical studies have shown that a combination of a tyrosine kinase inhibitor (TKI) and pemetrexed overcame acquired resistance to epidermal growth factor receptor (EGFR) TKI in NSCLC. Previously, pemetrexed+gefintib (P+G) had improved progression-free survival (PFS) compared with gefitinib. We present OS, updated PFS, biomarker analysis, and safety of P+G versus gefitinib. METHODS: intravenously...
