|ClinicalTrials.gov Identifier: NCT00749450|
Recruitment Status : Completed
First Posted : September 9, 2008
Last Update Posted : July 27, 2018
RATIONALE: Drugs used in chemotherapy, such as oxaliplatin, fluorouracil, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known which combination chemotherapy regimen is more effective in treating patients who have undergone surgery for high-risk colorectal cancer.
PURPOSE: This randomized phase III trial is studying chemotherapy given after surgery in treating patients with high-risk stage II or stage III colorectal cancer.
|Condition or disease||Intervention/treatment||Phase|
|Colorectal Cancer||Drug: capecitabine Drug: fluorouracil Drug: oxaliplatin||Phase 3|
- To assess the efficacy and compare the associated toxicity of adjuvant chemotherapy lasting 12 weeks vs 24 weeks in patients with fully resected high-risk stage II or III colorectal cancer.
- To conduct an economic analysis of the cost effectiveness of these regimens.
- To compare the randomization methodologies used in this study.
OUTLINE: This is a multicenter study. Patients are stratified according to participating center's recruitment potential. Patients are randomized (within 10 weeks after surgery and before or after receiving 12 weeks of chemotherapy) to 1 of 2 treatment arms. The treatment regimen that a patient receives (Oxaliplatin Modified DeGramont [OxMdG] or XELOX) is determined by the participating center.
- Arm I: Patients receive 12 courses of OxMdG (described below) or XELOX (described below)combination chemotherapy (6 additional courses if patient already received 6 courses) for treatment lasting a total of 24 weeks.
- Arm II: Patients receive 6 courses of OxMdG or XELOX combination chemotherapy (no additional courses if patient already received 6 courses) for treatment lasting a total of 12 weeks.
The two adjuvant combination chemotherapy regimens are administered as follows:
- OxMdG: Patients receive oxaliplatin IV over 2 hours and fluorouracil IV continuously over 46 hours on day 1. Treatment repeats every 14 days for 6 courses in the absence of disease progression or unacceptable toxicity.
- XELOX: Patients receive oxaliplatin IV over 2 hours on day 1 and oral capecitabine twice daily on days 1-14. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity.
Patients complete quality-of-life assessments periodically using the EORTC QLQ-C30, EORTC QLQ-CR29, EQ-5D, and GOG Ntx4 questionnaires.
After completion of study treatment, patients are followed periodically for up to 7 years.
