Study of Bevacizumab and Erlotinib in Patients With Advanced Non-small Cell Lung Cancer

There is no definite evidence of a superior therapy for advanced non-small cell lung cancer
in elderly patients. With the exception of one known study, single agent erlotinib has not
been studied exclusively in the elderly and the combination of erlotinib and bevacizumab has
never been studied exclusively in the treatment naive elderly. This is an important
population that needs less toxic therapies.
