The purpose of this study is to determine whether Icotinib is at least non-inferior to Gefitinib in the treatment of advanced non-small cell lung cancer (NSCLC) patients after one or two chemotherapies.
Lung cancer is the rapidest increased type of cancer in China with over 5 times incidence rate increase during the past 30 years . It is the leading cause of death of cancer in man and 2nd in women. With the development of gefitinib and erlotinib, EGFR-TKI (epidermal growth factor receptor -tyrosine kinase inhibitor) is the most successful novel drugs developed for the treatment of these patients in recent years, especially for NSCLC patients in Asia including China. Icotinib is a novel EGFR-TKI developed by a group of Chinese scientists and clinician. It appears to be at least as good as gefitinib in terms of efficacy and better in terms of safety in phase I/II trials. In this study, a randomized, double-blind, gefitinib as control, multi-center phase III trial was designed to evaluate the safety and efficacy of icotinib in the treatment of advanced NSCLC patients after failure of 1 or 2 chemotherapy. PFS (progress free survival) is the primary end-point with OS (overall survival), ORR (objective response), TTP (time to progress), HRQOL and safety as the secondary end-point. A total of 400 patients will be recruited. EGFR and K-ras gene mutational analysis as well as a population PK study have also been proposed.

Best Tumor Response

Change in size of tumor: Complete Response (CR) = no measurable tumor; Partial Response (PR) = 30% decrease in size of measurable tumor; Stable Disease (SD) = measurable tumor size has not changed; Progressive Disease (PD) = measurable tumor larger than at baseline

Safety and Tolerability

Adverse Events (AEs) and Serious AEs (SAEs) are presented regardless of causality for patients who received at least one dose of Icotinib or Gefitinib. Events were graded by the investigator using the NCI CTCAE Scale (version 3.0) which provides a grading scale for each AE term. Grade 3 = Severe Grade 4 = Life-threatening or disabling
