Condition(s) targeted: Colorectal Cancer

Intervention: Celecoxib (Drug); placebo (Other)

Phase: Phase 3

Status: Terminated

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. It is not yet known whether celecoxib is effective in preventing polyps in patients with colon cancer. PURPOSE: Randomized phase III trial to study the effectiveness of celecoxib in preventing the development of polyps in patients who have undergone surgery for stage I colon cancer.

Clinical Details

Official title: Celecoxib Polyp Prevention Trial in Participants With Resected Stage I Colon Cancer

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Prevention

Primary outcome: To determine whether celecoxib 400 mg bid for 3 years will decrease the incidence of adenomatous polyps of the colon and rectum in participants with Stage I adenocarcinoma of the colon.

Secondary outcome:

To access whether celecoxib will increase disease-free survival.

To access whether celecoxib therapy affects self-reported symptoms and health-related quality of life.

To describe the quality of life in early stage colon cancer patients.

To evaluate if the benefits from celecoxib are more pronounced in a cohort of participants whose primary colon tumors and polyps express COX-2.

To examine the expression of signaling targets such as serine/threonine kinase (AKT) extracellular signal-regulated kinase (ERK2), and endoplasmic reticulum Ca2+-ATPases in the index tumor and polyps.

To monitor the toxicity and safety of celecoxib in this population.

Detailed description: OBJECTIVES: Primary

- Compare celecoxib vs placebo, in terms of decreasing the incidence of adenomatous

polyps of the colon and rectum, in patients with resected stage I adenocarcinoma of the colon. Secondary

- Compare disease-free survival of patients treated with these regimens.

- Compare the effect of these regimens on self-reported symptoms and health-related

quality of life of these patients.

- Compare the quality of life of patients treated with these regimens.

- Compare the benefits of celecoxib in patients with primary tumors or polyps that

express cyclo-oxygenase-2 (COX-2) with those that do not express COX-2.

- Compare the expression of signaling targets such as serine/threonine AKT, extracellular

signal-regulated kinase 2 (ERK2), and endoplasmic reticulum Ca+2- ATPases in the index tumor and polyps.

- Determine the toxicity and safety of celecoxib in these patients.

OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to gender, tumor stage (T1 vs T2), age (≤ 49 vs 50 to 59 vs ≥ 60 years), and current aspirin use (yes vs no). Patients are randomized to 1 of 2 treatment arms.

- Arm I: Patients receive oral celecoxib twice daily for 3 years.

- Arm II: Patients receive oral placebo twice daily for 3 years. In both arms, treatment

continues in the absence of unacceptable toxicity or the diagnosis of invasive colon cancer, carcinoma in situ of the colon or rectum, or a non-colon primary cancer. Quality of life is assessed at baseline and then at 6, 12, 24, 36, and 42 months. Patients are followed at 6 months and at 2 years. PROJECTED ACCRUAL: A total of 1,200 patients (600 per treatment arm) will be accrued for this study within 2. 5 years.
