Special Category:
CTSU trial Objectives Primary - Compare the survival rate of patients with previously untreated metastatic adenocarcinoma of the colon or rectum treated with fluorouracil and leucovorin calcium with oxaliplatin or irinotecan and with or without cetuximab.
Secondary - Determine the level of epidermal growth factor receptor (EGFR) expression in patients treated with these regimens.
- Determine whether expression of EGFR activity, markers of EGFR activity, and serum levels of insulin-like growth factor-1, C-peptide, and insulin-like growth factor binding protein 3 are independent predictors of response rate, time to tumor progression, and survival of patients treated with these regimens.
- Correlate specific germline polymorphisms related to chemotherapy metabolism and resistance with treatment-related toxicity, tumor response, time to tumor progression, and survival of patients treated with these regimens.
- Correlate expression of putative prognostic markers in the tumor with tumor response, time to tumor progression, and survival of patients treated with these regimens.
- Correlate diet, obesity, physical activity, and other lifestyle habits with treatment-related toxicity, progression-free survival, and overall survival of patients treated with these regimens.

[Note: *In patients without a colostomy or ileostomy; patients with a colostomy or ileostomy are eligible at the discretion of the investigator] Expected Enrollment Approximately 2,200 patients (550 per treatment arm) will be accrued for this study within 4.6 years. Outline This is a randomized, open-label, multicenter study. Patients are stratified according to prior adjuvant therapy (yes vs no) and prior pelvic radiotherapy (yes vs no). Patients are randomized to 1 of 4 treatment arms. - Arm I (FOLFIRI): Patients receive irinotecan IV over 90 minutes and leucovorin calcium IV over 2 hours on days 1, 15, 29, and 43 and fluorouracil IV continuously over 46-48 hours beginning on days 1, 15, 29, and 43.
- Arm II (FOLFIRI and cetuximab): Patients receive FOLFIRI as in arm I and cetuximab IV over 1-2 hours on days 1, 8, 15, 22, 29, 36, 43, and 50.
- Arm III (FOLFOX): Patients receive oxaliplatin IV over 2 hours and leucovorin calcium IV over 2 hours on days 1, 15, 29, and 43 and fluorouracil IV continuously over 46-48 hours beginning on days 1, 15, 29, and 43.
- Arm IV (FOLFOX and cetuximab): Patients receive FOLFOX as in arm III and cetuximab IV over 1-2 hours on days 1, 8, 15, 22, 29, 36, 43, and 50.
In all arms, courses repeat every 8 weeks in the absence of disease progression or unacceptable toxicity. Patients are followed every 2 months for 2 years and then every 3 months for 3 years.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. Back to Top |
