Alternate Title

Rofecoxib After Surgery in Treating Patients With Stage II or Stage III Colorectal Cancer

Basic Trial Information

Phase	Type	Status	Age	Sponsor	Protocol IDs
Phase III	Treatment	Closed	18 and over	Other	CRC-TU-VICTOR EU-20054, CRC-TU-COX2, ISRCTN98278138, NCCTG-N004B, NCT00031863

Objectives

1. Compare the overall survival of patients with previously resected stage II or III colorectal cancer treated with rofecoxib vs placebo administered for at least 2 years vs 5 years.
2. Compare the relapse-free survival of patients treated with these regimens.

Entry Criteria

Disease Characteristics:

• Histologically confirmed colorectal carcinoma
  • Stage II (T3-4, N0, M0) or stage III (any T, N1-2, M0) disease
• Completely resected primary tumor without gross or microscopic evidence of residual disease
• Must have received potentially curative therapy within the past 12 weeks, including any of the following:
  • Surgery alone
  • Surgery plus radiotherapy and/or chemotherapy

Prior/Concurrent Therapy:

Biologic therapy:

• Not specified

Chemotherapy:

• See Disease Characteristics

Endocrine therapy:

• Not specified

Radiotherapy:

• See Disease Characteristics

Surgery:

• See Disease Characteristics

Other:

• No concurrent long-term NSAIDs except low-dose aspirin (no more than 80 mg/day) for cardio-prophylaxis

Patient Characteristics:

Age:

• 18 and over

Performance status:

• WHO 0-1

Life expectancy:

• Not specified

Hematopoietic:

• Absolute neutrophil count at least 1,500/mm³
• Platelet count at least 100,000/mm³

Hepatic:

• Bilirubin no greater than 1.5 times upper limit of normal (ULN)
• AST/ALT no greater than 1.5 times ULN

Renal:

• Creatinine clearance greater than 30 mL/min

Cardiovascular:

• No severe congestive heart failure

Other:

• Not pregnant or nursing
• Fertile patients must use effective contraception
• No active peptic ulcer or gastrointestinal bleeding within the past year
• No inflammatory bowel disease
• No known sensitivity to rofecoxib
• No prior adverse reaction to non-steroidal anti-inflammatory drugs (NSAIDs) (e.g., asthma, acute rhinitis, nasal polyps, angioneurotic edema, or urticaria)
• No other malignancy within the past 10 years except adequately treated carcinoma in situ of the cervix or basal cell or squamous cell skin cancer

Expected Enrollment

A total of 7,000 patients (1,750 per treatment arm) will be accrued for this study within 5 years.

Outline

This is a randomized, placebo-controlled, double-blind, multicenter study. Patients are stratified according to participating center, site of disease (colon vs rectum), disease stage (II vs III), age, adjuvant chemotherapy (yes vs no), and type of chemotherapy regimen (1 vs 2 vs 3 vs 4 vs 5). Within 3 months of surgical resection alone or completion of adjuvant radiotherapy and/or chemotherapy after surgical resection, patients are randomized to one of four treatment arms.

• Arm I: Patients receive oral rofecoxib once daily for 2 years.
• Arm II: Patients receive oral rofecoxib once daily for 5 years.
• Arm III: Patients receive oral placebo once daily for 2 years.
• Arm IV: Patients receive oral placebo once daily for 5 years.

Treatment continues in all arms in the absence of disease recurrence or unacceptable toxicity.
