Background: This trial focused on optimally combining existing targeted therapies and cytotoxic chemotherapy in the treatment of unselected patients with advanced nonsmall-cell lung cancer (NSCLC). Methods: Patients with previously untreated advanced-stage nonsquamous NSCLC were eligible for this trial. In module A, patients received up to 4 cycles of erlotinib 150 mg daily and bevacizumab 15 mg/kg every 3 weeks. Patients then received carboplatin (AUC = 6), paclitaxel 200 mg/m2, and bevacizumab 15 mg/kg for 4 cycles in module B. Patients who did not have progressive disease in module A received maintenance erlotinib 150 mg daily and bevacizumab 15 mg/kg every 3 weeks in module C. Results: Forty-eight patients were enrolled in this multicenter phase II trial. Most patients were male (62.5%) and white (77.1%) with stage IV disease (93.8%) and adenocarcinoma histologic type (66.7%). The overall response rate in module A was 10.4%, in module B it was 15.1%, and in module C it was 5.5%. The study achieved its primary endpoint, with a nonprogression rate of 45.8% in module A. The median overall survival (OS) was 12.6 months. Conclusion: The novel systemic therapy regimen is feasible in patients with advanced NSCLC. However there is no further role for developing this regimen in unselected patients with NSCLC.
