Brief Summary:
The investigators hypothesize that the combination of eflornithine and sulindac will be effective in reducing a three-year event rate of adenomas and second primary colorectal cancers in patients previously treated for Stages 0 through III colon or rectal cancer.

Condition or disease Intervention/treatment Phase
Colorectal Neoplasms Drug: Eflornithine placebo & sulindac placebo Drug: eflornithine & sulindac placebo Drug: Eflornithine placebo & sulindac Drug: Eflornithine plus sulindac Phase 3

Detailed Description:
The purpose of this study is to assess whether the combination of eflornithine 500 mg and sulindac 150 mg (compared to corresponding placebos) has efficacy against colorectal lesions with respect to high-grade dysplasia, adenomas with villous features, adenomas 1 cm or greater, multiple adenomas, any adenomas >/= 0.3 cm, total advanced colorectal events, or total colorectal events.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 3-year event rate after registration among Stage 0-III colon or rectal cancer patients. (An event is defined as high-risk adenoma or second primary colorectal cancer.) [ Time Frame: 3 years ]
    The primary objective is to assess whether the combination of eflornithine 500 mg and sulindac 150 mg is effective in reducing the 3-year event rate, defined as high risk adenoma or 2nd primary colorectal cancer, in patients with previously treated Stage 0, I, II, and III colon or rectal cancer.


Secondary Outcome Measures :
  1. Incidence of colorectal lesions with respect to high-grade dysplasia, adenomas with villous features, adenomas 1 cm or greater, multiple adenomas, polyps >/= 0.3 cm, total advanced colorectal events or total colorectal events at 3 years. [ Time Frame: 3 years and 8 years ]
    Incidence of colorectal lesions with respect to high grade dysplasia, adenomas with villous features, adenomas 1 cm or greater, multiple adenomas, polyps >/= 0.3 cm, total advanced colorectal events (defined as the number of patients with at least one high risk adenoma, 2nd primary colorectal cancer, colorectal cancer recurrence, or metastasis) or total colorectal cancer events (defined as the number of patients with at least one advanced colorectal event or polyp)at 3 years and 8 years.

  2. Toxicity by CTCAEv.4.0 at 3 years [ Time Frame: 3 years ]
    Quantitative and qualitative toxicities at 3 years.

  3. Examine interaction of treatment arm and genotype expression with respect to different outcomes. [ Time Frame: 3 years and 8 years ]
  4. Interaction of intervention arm and baseline statin use with respect to 3-year event rate. [ Time Frame: 3 year ]
    Interaction of intervention arm and baseline statin use with respect to 3-year event rate will be examined.

  5. Evaluate SNPs associated with decreased adenoma/second primary CRC risk and AEs [ Time Frame: 3 years and 8 years ]
    Evaluate a minimal set of tagging single nucleotide polymorphisms across multiple genes relevant to eflornithine and sulindac, in order to characterize associations with decreased adenoma/second primary CRC risk and adverse events.

  6. Interaction of the intervention arm and patient-reported meat consumption with respect to the 3-year event rate [ Time Frame: 3 year ]
    To explore the interaction of the intervention arm and patient-reported meat consumption with respect to the 3-year event rate.
