Safety And Efficacy Results Of A Phase Iv, Open-Label, Multicenter, Safety-Monitoring Study Of Icotinib In Treating Advanced Non-Small Cell Lung Cancer (Nsclc): Isafe Study.

e19161 Background: The phase III ICOGEN trial established the non-inferiority of icotinib to gefitinib in terms of progression-free survival (PFS), based on which icotinib was approved by State Food and Drug Administration of China. We conducted a safety-monitoring study to assess the safety and efficacy of icotinib in a broad range of patients with advanced non-small-cell lung cancer (NSCLC) across China. Methods: This study was a single-arm, open-label, multi-center trial in advanced NSCLC patients who were suitable for treatment with oral icotinib 125 mg three times daily. Endpoints included safety, objective response rate (ORR) and disease control rate (DCR), were investigated overall and in subgroups. EGFR mutation analysis was performed retrospectively. Results: Between August, 2011 and August, 2012, 6,087 advanced NSCLC patients were registered with a median age of 63 years (range: 21-95 years), and 5,549 patients were evaluable for safety and tumor response. Baseline characteristics (%) were: male...
