A Study of Erlotinib Plus Radiotherapy (RT) for Patients With Advanced or Inoperable Non-Small-Cell Lung Cancer

Patients will receive Tarceva, 150 mg daily on days -5 through -1 days and will start a course of hypofractionated thoracic RT on Day 1. RT will be administered daily on weekdays (Monday-Friday) and not on weekends or holidays. Tarceva administration will be continued daily during RT (also on weekends/holidays when RT is not given) and after RT will be continued daily as maintenance therapy until death or disease progression.

Patients undergo hypofractionated thoracic RT 5 days a week for approximately 2.5 weeks beginning on day 0. Patients also receive erlotinib hydrochloride PO daily beginning on day -5 and continuing for up to 24 months in the absence of disease progression or unacceptable toxicity.
