This 2 arm study will evaluate the efficacy, safety, and pharmacokinetics of Tarceva, compared with placebo, following platinum-based chemotherapy in patients with advanced, recurrent, or metastatic NSCLC who have not had disease progression or unacceptable toxicity during chemotherapy. Following 4 cycles of platinum-based chemotherapy, eligible patients will be randomized to receive either Tarceva 150mg po daily, or placebo daily. The anticipated time on study treatment is until disease progression; the target sample size is 500+ individuals.

Percentage of Participants With PD According to Response Evaluation Criteria in Solid Tumors (RECIST) or Death (Data Cutoff 17 May 2008)

For target lesions (TLs), PD was defined at least a 20 percent (%) increase in the sum of the largest diameter (SLD), taking as reference the smallest SLD recorded from baseline (BL) more the appearance of one or more new lesions. For non-target lesions (NTLs), PD was defined as the appearance of 1 or more new lesions and/or unequivocal progression of existing NTLs. Participants without PD or death were censored at the date of last tumor assessment where non-progression was documented.
