A Randomized, Open-label Study Comparing the Anti-tumor Effect of Treatment With Tarceva Plus Avastin Versus Chemotherapy Plus Avastin in Patients With Advanced Non-small Cell Lung Cancer

This 2 arm study will compare the efficacy and safety of Tarceva plus Avastin, and chemotherapy plus Avastin, in the first-line treatment of patients with advanced non-small cell lung cancer. Patients will be randomized to receive either Tarceva 150mg p.o. daily plus Avastin 15mg/kg i.v. every 3 weeks, or standard platinum-based chemotherapy (4-6 cycles) plus Avastin. The anticipated time on study treatment is until disease progression, and the target sample size is 100-500 individuals.
