Summary
This is a double blind, multicentre, randomized, placebo-controlled study. The eligible patients will be randomized to receive gefitinib or placebo at 1:1 ratio. This study will recruit 296 male or female, histologically or cytologically diagnosed locally advanced or metastatic NSCLC patients with a World Health Organization (WHO) Performance Status (PS) 0-2.
