Metronomic therapy with 5-FU, weekly nab-paclitaxel, leucovorin, and oxaliplatin, plus bevacizumab for advanced pancreatic cancer: A phase II study.

e14582 Background: The objective of this open label phase 2 study was to evaluate low-dose continuous (metronomic) chemotherapy given in conjunction with conventional anti-VEGF therapy for patients with advanced pancreatic cancer. Continuous infusion of 5FU, calcium leucovorin plus paclitaxel and oxaliplatin has been shown to be active in patients with pancreatic cancer. As a protracted low dose infusion, 5FU is anti-angiogenic and has been demonstrated to be synergistic with bevacizumab. Bevacizumab and nab-paclitaxel are synergistic as seen in the treatment of breast cancer. Methods: Since July 2008, we treated 40 patients with 5FU (180mg/m2/day x 14 days) via an ambulatory pump. Calcium leucovorin (20mg/m2) IVP, nab-paclitaxel (100mg/m2) IV as a 30 minute infusion and oxaliplatin (75mg/m2) IV as a 60 minute infusion were given on days 1, 8, and 15. Bevacizumab (5mg/kg) IV over 30 minutes was given on days 1 and 15. Cycles were repeated every 35 days. There were 24 females and 16 males. The median age w...
