title: A phase II study of oxaliplatin, pemetrexed, and bevacizumab in previously treated advanced non-small cell lung cancer.
abstract: BACKGROUND
  Single agent chemotherapy is standard for second and third line treatment of non-small cell lung cancer (NSCLC). Combination therapy to date has not proven to be superior to single agents in this setting, often adding toxicity without any additional efficacy. We investigated the activity and tolerability of the combination of oxaliplatin, pemetrexed, and bevacizumab in patients with previously treated advanced NSCLC.
  
  
  METHODS
  This multicenter phase II trial evaluated the safety and efficacy of the combination of pemetrexed (500 mg/m), oxaliplatin (120 mg/m), and bevacizumab (15 mg/kg), given every 21 days, in patients with previously treated advanced NSCLC. Eligibility criteria included performance status 0 to 1, nonsquamous histology, and at least one prior chemotherapy regimen. Patients with treated brain metastases were allowed. The primary end point was response rate, with secondary endpoints of progression-free survival and overall survival.
  
  
  RESULTS
  Thirty-six patients were enrolled on this study. Treatment was well tolerated; the most common grade 3 toxicity was hypertension, which was easily managed with oral medications. The nine (25%) patients with treated brain metastases had no episodes of cerebral hemorrhage. Of the 34 patients evaluable for tumor response, none had complete response, nine (27%) had partial response, 15 (44%) had stable disease, and 10 (29%) had progressive disease. Median progression-free survival was 5.8 months (95% confidence interval 4.1-7.8 months) and median overall survival was 12.5 months (95% confidence interval 7.3-17 months).
  
  
  CONCLUSIONS
  Treatment with oxaliplatin and pemetrexed in combination with the targeted antiangiogenic agent bevacizumab yielded promising efficacy with manageable toxicity in the previously treated advanced NSCLC population.
