BACKGROUND: The authors performed a phase 2 study of bevacizumab plus pemetrexed and carboplatin followed by maintenance bevacizumab in patients with advanced, nonsquamous nonsmall cell lung cancer. METHODS:Previously untreated patients with advanced, nonsquamous nonsmall cell lung cancer and an Eastern Cooperative Oncology Group performance status of 0 or 1 receivedbevacizumab 15 mg/kg, pemetrexed 500 mg/m(2) and carboplatin at an area under the concentration-time curve of 6 intravenously on day 1 every 21 days. Responding or stable patients who completed 6 cycles then received bevacizumab maintenance every 21 days until disease progression. RESULTS: In total, 43 patients (40 who were evaluable for response) were entered on the study. Treatment-related grade 3/4 toxicities were low and included febrile neutropenia (2%), neutropenia (28%), anemia (18%), thrombocytopenia (11%), hypertension (7%), epistaxis (5%), venous thrombosis (8%), dyspnea (7%), rectovaginal fistula (2.3%), infusion reaction (2%), and cerebrovascular event (2%). One patient died from complications of venous thromboembolism and cerebrovascular accident after Cycle 2. Minimal clinically significant toxicity occurred during maintenance bevacizumab. Two complete responses (5%) were observed, and 17 patients (42%) had a partial response. Fifteen patients (38%) displayed disease stability. The overall disease control rate was 85%. At a median follow-up of 15.8 months, the median progression-free survival was 7.1 months (95% confidence interval, 5.9-8.3 months), and the median overall survival was 17.1 months (95% confidence interval, 8.8-25.5 months). CONCLUSIONS:Combined bevacizumab, pemetrexed, and carboplatin followed by maintenance bevacizumab was well tolerated and displayed remarkable activity in patients with previously untreated, advanced, nonsquamous nonsmall cell lung cancer.
