A Phase II Trial of the Combination of OSI-774 (Erlotinib; NSC-718781) and Bevacizumab (RHUMAB VEGF; NSC 704865) in Never-Smokers With Stage IIIB and IV Primary NSCLC Adenocarcinomas
A Phase II Trial of the Combination of OSI-774 (Erlotinib; NSC-718781) and Bevacizumab (RHUMAB VEGF; NSC 704865) in Never-Smokers With Stage IIIB and IV Primary NSCLC Adenocarcinomas
RATIONALE: Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab also may stop the growth of non-small cell lung cancer by blocking blood flow to the tumor. Giving erlotinib together with bevacizumab may kill more tumor cells.
PURPOSE: This phase II trial is studying how well giving erlotinib together with bevacizumab works in treating patients with stage IIIB or stage IV primary non-small cell lung cancer who have never smoked.
OBJECTIVES:
Primary
Secondary
OUTLINE: This is a multicenter study.
Patients receive oral erlotinib hydrochloride daily on days 1-21 and bevacizumab IV over 30-90 minutes on day 1. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed periodically for up to 3 years.
PROJECTED ACCRUAL: A total of 80 patients will be accrued for this study.
