Eniluracil and Surgery in Treating Patients With Primary or Metastatic Colorectal Cancer

Colorectal Cancer Clinical Trial

Official title:
Evaluation of Dihydropyrimidine Dehydrogenase (DPD) Activity in Surgically Resected Primary and Metastatic Colorectal Cancer After 48 hr Pretreatment With Eniluracil

Clinical Trial Summary

RATIONALE: Eniluracil may increase the effectiveness of chemotherapy by blocking tumor enzymes that break down chemotherapy drugs.

PURPOSE: Randomized phase II trial to determine the effectiveness of eniluracil followed by surgery in treating patients who have primary or metastatic colorectal cancer.

Clinical Trial Description

OBJECTIVES: I. Determine the enzymatic activity of dihydropyrimidine dehydrogenase (DPD) in peripheral blood mononuclear cells (PBMC), normal mucosa, or normal liver in patients with primary or metastatic colorectal cancer. II. Evaluate the ability of eniluracil to inactivate DPD in the tumor, PBMCs, and normal tissue in this patient population. III. Assess DPD recovery and uracil levels in PBMCs following surgical resection in these patients.

OUTLINE: This is a randomized, placebo controlled study. Patients are stratified according to colorectal tumor (primary vs metastatic). Patients are randomized into one of two treatment arms. Arm I: Patients receive oral eniluracil twice daily on days -2 and -1 followed by surgical resection and tissue harvest on day 0. Arm II: Patients receive an oral placebo as in arm I followed by surgical resection and tissue harvest on day 0. Patients are followed weekly for 1 month.

PROJECTED ACCRUAL: A total of 20 patients (10 per treatment arm) will be accrued for this study. ;

Allocation: Randomized, Endpoint Classification: Pharmacokinetics/Dynamics Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Treatment
