This is a study to evaluate the effectiveness of erlotinib compared with a placebo sugar pill following complete surgical removal of the tumor with or without chemotherapy after surgery in Stage IB-IIIA NSCLC patients.
After the initiation of the study, the sponsor became aware of an error in the drug dispensing module of the interactive voice response such that most patients who were randomized prior to 07 November 2007 were dispensed the incorrect study drug at least once. Since the integrity of the data from these patients was seriously compromised, these patients were considered unevaluable for the protocol-specified analyses. These participants are referred to as the breached protocol cohort (BPC) and those still on study treatment at the time of the breach were offered the option of receiving open-label erlotinib for up to 2 years (including posttreatment and long-term follow-up assessments), not receiving open-label erlotinib but remaining in the study for posttreatment and long-term follow-up assessment, or withdrawing consent from treatment and further assessments. Participants who had discontinued study treatment prior to the breach were not offered open-label erlotinib and remained in long-term follow-up. Data from the BPC participants were analyzed separately and were not included in the assessments of primary or secondary endpoints in the randomized cohort and were not considered part of the primary analyses.The sample size for the randomized cohort was not changed due to the BPC and the data from RC and BPC were analyzed separately.

Disease Free Survival (DFS)
DFS is the time from the date of randomization until the first day non-small cell lung cancer (NSCLC) relapse is documented by radiological exam and/or biopsy, or until death in the absence of relapse. After randomization, NSCLC relapse was based on radiological evidence or biopsy, as determined by the investigator. Participants without a DFS event were censored on the last adequate radiological assessment date.
Time frame: Every 3 months during active phase and every 6 months during long term follow-up up to 5 years and yearly thereafter until the data cut-off date of 08 April 2013 (maximum time on follow-up was 64 months).

Time frame: Every 3 months during active phase and every 6 months during long term follow-up up to 5 years and yearly thereafter until the data cutoff date of 11 June 2014 (maximum time on follow-up was 78 months).
Overall Survival (OS)
Overall survival was defined as the time from the date of randomization until the documented date of death. Participants who were still alive were censored on the last day they were known to be alive.

Disease-free Survival in Participants With EGFR Mutation - Positive Tumors
Disease-free survival (DFS) is the time from the date of randomization until the first day NSCLC relapse is documented by radiological exam and/or biopsy, or until death in the absence of relapse. After randomization, NSCLC relapse was based on radiological evidence or biopsy, as determined by the investigator. Participants without a DFS event were censored on the last adequate radiological assessment date. Activating EGFR mutation-positive is defined as exon 19 deletion or exon 21 L858R (or both) detected.
Time frame: Every 3 months during active phase and every 6 months during long term follow-up up to 5 years and yearly thereafter until the data cut-off date of 08 April 2013 (maximum time on follow-up was 64 months).

Number of Participants With Adverse Events (AEs)
An AE was defined as any untoward medical occurrence in a study participant and did not necessarily have a causal relationship with study treatment. An AE was considered serious if it resulted in death, a life-threatening situation, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect in the offspring of a participant, other important medical events, or is on the Astellas Always Serious List. A drug-related AE was any AE with at least a possible relationship to study treatment as assessed by the investigator. Severity was graded by the investigator according to the National Cancer Institute Common Terminology Criteria for Adverse Events, v3.0, where Grade 1=Mild AE; Grade=2 Moderate AE; Grade 3=Severe AE; Grade 4=Life-threatening or disabling; Grade 5=Death related to AE. AEs leading to death include deaths that occurred more than 30 days after the last dose of study drug.
Time frame: From the date of first dose of study drug until 30 days after the last dose. The median time on treatment was 11.9 months for erlotinib and 21.9 months for placebo. Data are based off the 11 June 2014 data cut-off date.
