Ropidoxuridine in Treating Patients With Advanced Gastrointestinal Cancer Undergoing Radiation Therapy


This phase I trial studies the side effects and best dose of ropidoxuridine in treating patients with gastrointestinal cancer that have spread to other places in the body and usually cannot be cured or controlled with treatment undergoing radiation therapy. Ropidoxuridine may help radiation therapy work better by making tumor cells more sensitive to the radiation therapy.

  • Patients with known brain metastases should be excluded from this clinical trial
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to IPdR
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
