Gemcitabine, docetaxel, and capecitabine (GTX) in the treatment of metastatic pancreatic cancer (PC): A prospective phase II study

14024 Background: We have found that the combination of gemcitabine, docetaxel, and capecitabine (GTX), when administered in a specific sequence, will induce a p53 independent pathway of cell death through the MAP kinase pathway. The sequence overcomes drug resistance in PC cells in vitro. We have begun a prospective, phase II trial of GTX in patients with metastatic PC as first-line therapy. Methods: 23 patients with metastatic PC, ECOG 0–2 were enrolled at either Columbia or a community practice. Each cycle was administered over a 21 days. Capecitabine was administered at 750 mg/m2 twice daily for 14 days. Gemcitabine (750 mg/m2 over 75 minutes) and docetaxel (30 mg/m2) were administered on days 4 and 11. Responses were measured by CT (RECIST) and PET after every three cycles. A response by PET was defined as a 50% reduction in SUV while a CR was an absence of uptake. Results: Median age was 61, including 8 men and 15 women. Metastatic sites included liver (87%), abdomen (65%), and lung (17%). 70% of li...
