Progression-Free Survival (PFS)

PFS was defined as the time from initial dose of erlotinib to progression or death from any cause.

Percentage of Participants With Overall Response

Overall response was defined, based on response evaluation criteria in solid tumours (RECIST) v 1.1, as complete response (CR) plus partial response (PR). CR: complete disappearance of all target lesions; PR: at least 30% decrease in the sum of the longest diameter of all target lesions taking as reference the baseline sum of all target lesions.

Proportions of Participants With Adverse Events (AEs), Serious AEs, and AEs of Special Interest (AESIs)

An AE was considered any unfavorable and unintended sign, symptom, or disease associated with the use of the study drug, whether or not considered related to the study drug. Preexisting conditions that worsened during the study and laboratory or clinical tests that resulted in a change in treatment or discontinuation from study drug were reported as adverse events. A SAE was any experience that suggests a significant hazard, contraindication, side effect or precaution that: results in death, is life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or is medically significant, according to national cancer institute (NCI) common terminology criteria for adverse events (CTCAE) criteria version 4.0.
