Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

OUTLINE: This is a multicenter study. Patients are stratified according to number of positive lymph nodes\* (1-3 vs 4 or more) and concurrent regular low-dose of aspirin (yes vs no). Patients are randomized to 1 of 4 treatment arms. Please see the "Arms" section for more information. In all arms, treatment with celecoxib or placebo continues for 3 years in the absence of disease progression or unacceptable toxicity. Blood and tissue samples maybe collected for biomarker analysis and pharmacogenomic studies. The primary and secondary objectives for the research study are described below.

Primary objective:

1\. To compare disease-free survival of patients with stage III colon cancer randomized to standard chemotherapy only FOLFOX or standard chemotherapy FOLFOX with 3 years of celecoxib 400 mg daily.

Secondary objectives:

1. To contribute to an international prospective pooled analysis that will compare disease-free survival of patients with stage III colon cancer randomized to 6 treatments of adjuvant FOLFOX chemotherapy or 12 treatments of adjuvant FOLFOX chemotherapy.
2. To compare overall survival of patients with stage III colon cancer randomized to standard chemotherapy only (FOLFOX) or standard chemotherapy (FOLFOX) with 3 years of celecoxib 400 mg daily.
3. To contribute to an international prospective pooled analysis that will compare overall survival of patients with stage III colon cancer randomized to 6 treatments of adjuvant FOLFOX chemotherapy or 12 treatments of adjuvant FOLFOX chemotherapy or 12 treatments of adjuvant FOLFOX chemotherapy.
4. To assess toxicities of celecoxib as maintenance adjuvant therapy in patients with stage III colon cancer.
5. To assess differences in cardiovascular-specific events with celecoxib versus placebo in a population of stage III colon cancer survivors.
6. To evaluate differences in toxicities, particularly cumulative peripheral neuropathy, for patients treated with 6 treatments of FOLFOX compared to those treated with 12 treatments of FOLFOX.

After completion of study therapy, patients are followed up every 6 months for up to 6 years.

Patients receive 400 mg/m\^2 intravenous over two hours.

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

2. Tumors must have been completely resected. In patients with tumor adherent to adjacent structures, en bloc R0 resection must be documented in the operative report or otherwise confirmed by the surgeon. Near or positive radial margin are not exclusions as long as en bloc resection was performed. Positive proximal margin or distal margin is an exclusion.
3. Node positive disease (N1 or N2) as designated in AJCC version 7. Either at least one pathologically confirmed positive lymph node or N1C (defined as tumor deposit(s) in the subserosa, mesentery, or nonperitonealized pericolic or perirectal tissues without regional lymph node metastases). Patients with resected stage IV disease are not eligible.
4. No evidence of residual involved lymph node disease or metastatic disease at the time of registration.
5. Patients with synchronous colon cancers are eligible and staging for stratification will be based on higher N stage of the more advanced primary tumor. However, patients with synchronous colon and rectal primary tumors are not eligible.
2. NSAID use

Patients are ineligible if they plan on regular use of NSAIDs at any dose more than 2 times per week (on average) or aspirin at more than 325 mg at least three times per week, on average. Low-dose aspirin not exceeding 100 mg/day is permitted. Patients who agree to stop regular NSAIDs or higher dose aspirin are eligible and no was out period is required.
3. Patient history

1. No previous or concurrent malignancy, except treated basal cell or squamous cell cancer of skin, treated in situ cervical cancer, treated lobular or ductal carcinoma in situ in one breast, or any other cancer for which the patient has been disease-free for at least 5 years.
2. No neurosensory or neuromotor toxicity ≥ grade 2 at the time of registration.
3. No known allergy to platinum compounds.
4. No prior allergic reaction or hypersensitivity to sulfonamides, celecoxib or NSAIDs.
5. No history of upper gastrointestinal ulceration, upper gastrointestinal bleeding, or upper gastrointestinal perforation within the past 3 years. Patients with ulceration, bleeding or perforation in the lower bowel are not excluded.
6. No symptomatic pulmonary fibrosis or interstitial pneumonitis ≥ grade 2.
7. No cardiac risk factors including:

* Uncontrolled high blood pressure (systolic blood pressure \> 150).
* Unstable angina.
* History of documented myocardial infarction or cerebrovascular accident.
* New York Heart Association class III or IV heart failure.
4. Pregancy/nursing status

Non-pregnant and not nursing. Men and women of childbearing potential must agree to employ adequate contraception for the duration of chemotherapy and for as many as 8 weeks after the completion of chemotherapy due to the unknown teratogenic effects of FOLFOX on the developing fetus.
5. Age and performance status

1. ECOG performance status 0, 1 or 2.
2. Age at least 18 years.
6. Required initial laboratory values

1. Granulocytes ≥ 1,500/μL
2. Platelet count ≥ 100,000/μL
3. Creatinine ≤ 1.5 times upper limit of normal (ULN)
4. Total Bilirubin ≤ 1.5 times ULN in the absence of Gilbert's disease
5. Direct bilirubin ≤ 1.5 x upper limit of normal for patients with Gilbert's syndrome
