A Study of Tarceva (Erlotinib) Following Platinum-Based Chemotherapy in Patients With Advanced, Recurrent, or Metastatic Non-Small Cell Lung Cancer (NSCLC)

Progression-free survival (PFS) was defined as the time from randomization to PD or death, whichever occurred first. 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.

The median time, in weeks, from randomization to PFS event. Participants without PD or death were censored at the date of last tumor assessment where non-progression was documented. The 95% confidence interval (CI) was estimated using Kaplan-Meier methodology.

LCS scores were obtained from a 7-item questionnaire from the Functional Assessment of Cancer Therapy - Lung (FACT-L) version (V) 4. Participants responded to questions assessing symptoms commonly reported by lung cancer patients; such as shortness of breath, loss of weight, and tightness in chest; on a scale from 0-4, where 0 equaled (=) "not at all" and 4 = "very much." The participants' responses were summed to result in an overall score, where a higher score indicated more severe symptoms. A change of 2 to 3 points in score was determined to be a clinically meaningful decline.
