Outline

This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are randomized to 1 of 4 treatment arms.

  • Arm I: Patients receive oral aspirin and oral folic acid daily.

  • Arm II: Patients receive oral aspirin and oral placebo daily.

  • Arm III: Patients receive oral placebo and oral folic acid daily.

  • Arm IV: Patients receive 2 oral placebos daily.

In all arms, treatment continues for 3 years in the absence of unacceptable toxicity.

After completion of the 3-year intervention, all patients undergo a surveillance colonoscopy.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
