Triacetyluridine and Fluorouracil Compared With Gemcitabine in Treating Patients With Unresectable Locally Advanced, or Metastatic Pancreatic Cancer
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving the drugs in different combinations may kill more tumor cells. Chemoprotective drugs such as triacetyluridine may protect normal cells from the side effects of chemotherapy. It is not yet known which chemotherapy regimen is more effective in treating pancreatic cancer.
PURPOSE: Randomized phase III trial to compare the effectiveness of fluorouracil plus triacetyluridine with that of gemcitabine in treating patients who have locally advanced or metastatic pancreatic cancer that cannot be treated with surgery.

|Official Title:||An Open Label, Randomized, Controlled, Phase III, Multi-center, Clinical Trial Of PN401 With High Dose 5-Fluorouracil (5FU) Versus Gemcitabine For Treatment Of Patients With Advanced Pancreatic Cancer|
- Open Label Randomized Phase 3 Multi-Center Trial of PN401 plus high dose 5-FU versus Gemcitabine in Advanced Pancreatic Cancer Patients [ Time Frame: Disease progression ]
|Study Start Date:||February 2001|
|Primary Completion Date:||February 2006 (Final data collection date for primary outcome measure)|
- Compare the survival of patients with unresectable locally advanced or metastatic pancreatic cancer treated with triacetyluridine and high-dose fluorouracil vs gemcitabine.
- Compare the time to tumor progression, overall response rate, and response duration in patients treated with these regimens.
- Compare the safety of these regimens in these patients.
OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to disease stage (II or III vs IV). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive high-dose fluorouracil (5-FU) IV over 30 minutes once weekly on weeks 1-3 followed by 1 week of rest. After each dose of 5-FU, patients receive oral triacetyluridine every 8 hours for a total of 8 doses. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.
- Arm II: Patients receive gemcitabine IV over 30 minutes once weekly on weeks 1-7 followed by 1 week of rest (course 1). Subsequent courses are given on weeks 1-3. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.
Patients are followed for survival.
PROJECTED ACCRUAL: A total of 260 patients (130 per treatment arm) will be accrued for this study within 30 months.
