Alternate Title

Triacetyluridine and Fluorouracil Compared With Gemcitabine in Treating Patients With Unresectable Locally Advanced, or Metastatic Pancreatic Cancer

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase III Supportive care, Treatment Closed 18 and over Pharmaceutical / Industry WELLSTAT-401.00.001 PRONEURON-401.00.001, UAB-0105, UAB-F010524008, NCT00024427

Objectives

1. Compare the survival of patients with unresectable locally advanced or metastatic pancreatic cancer treated with triacetyluridine and high-dose fluorouracil vs gemcitabine.
2. Compare the time to tumor progression, overall response rate, and response duration in patients treated with these regimens.
3. Compare the safety of these regimens in these patients.

Entry Criteria

Expected Enrollment

A total of 260 patients (130 per treatment arm) will be accrued for this study within 30 months.

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.
