Summary
Brief summary (as posted)
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. Patients must have completed 4 cycles of platinum based first line doublet chemotherapy without experiencing disease progression or unacceptable toxicity. The chemotherapy shall be given every 3 weeks, which includes cisplatin or carboplatin, combined with any one of the following: gemcitabine, paclitaxel, docetaxel, vinorelbine.

Inclusion Criteria: * Histologically or cytologically confirmed locally advanced or metastatic (stage=IIIB/IV) non-small cell lung cancer (NSCLC) before the front line chemotherapy. Note: sputum cytology alone is not acceptable * Patients have completed 4 cycles of first line platinum contained doublet chemotherapy without progression or intolerable toxicity. * Patients with PR or SD on study entry need to have one or more measurable lesions according to RECIST criteria. * The study treatment should be started at least 3 weeks (21 days) but no more than 6 weeks (42 days) since last dose of chemotherapy, and within 4 weeks (28 days) since last tumour assessment. Exclusion Criteria: * Prior exposure to monoclonal antibodies or small molecule inhibitors against EGFR receptors. (e.g. gefitinib, erlotinib, C225) * Patients with previously diagnosed and treated CNS metastases or spinal cord compression may be considered if they are clinically stable and have been discontinued from steroid therapy for at least 4 weeks prior to first dose of study medication. * Any evidence of clinically active interstitial lung disease (patients with chronic, stable, radiographic changes who are asymptomatic need not be excluded) * Known biomarker status of one or more of the following: Tumour EGFR gene copy number, tumour EGFR gene mutation status, tumour EGFR protein expression.
