|Phase II||Treatment||Closed||18 and over||NCI||ECOG-E4203|
Special Category: NCI Web site featured trial, NCI - CMS pilot project trial
- Compare the response rate (complete and partial), progression-free survival, and overall survival of patients with previously untreated metastatic or locally recurrent colorectal adenocarcinoma with high vs low thymidylate synthase (TS) expression treated with fluorouracil, leucovorin calcium, oxaliplatin, and bevacizumab or irinotecan, oxaliplatin, and bevacizumab.
- Compare the toxicity of these regimens in these patients.
- Correlate gene expression with response rates in patients treated with these regimens.
- Correlate gene expression with toxicity of these regimens in these patients.
- Correlate dihydropyrimidine dehydrogenase, thymidine phosphorylase, and mammalian excision repair cross complementary protein expression with antitumor response in patients treated with these regimens.

A total of 117-246 patients (40-72 in arm I, 40-72 in arm II, 37-102 in arm III) will be accrued for this study within 14-23 months.
Response rate (complete response [CR] and partial response [PR]) as measured by RECIST
Progression-free survival as measured by time to event at 1 year after closure to accrual
Overall survival as measured by time to event at 1 year after closure to accrual
Toxicity as measured by NCI CTCAE v4.0 at 1 year after closure to accrual
This is a randomized, multicenter study. Patients are stratified according to thymidylate synthase (TS) expression levels (high vs low or indeterminate). Patients with high TS expression are randomized to 1 of 2 treatment arms (arms I or II). Patients with low or indeterminate TS expression are assigned to arm III.
- Arm I: Patients receive bevacizumab IV over 30-90 minutes followed by oxaliplatin IV over 2 hours and irinotecan IV over 90 minutes on days 1 and 15.
- Arm II: Patients receive bevacizumab and oxaliplatin as in arm I, leucovorin calcium IV over 2 hours, and fluorouracil IV over 5 minutes and then continuously over 46 hours on days 1 and 15.
- Arm III: Patients receive bevacizumab, oxaliplatin, leucovorin calcium, and fluorouracil as in arm II.
In all arms, courses repeat every 28 days in the absence of unacceptable toxicity or disease progression.
Patients are followed up every 3 months for 2 years and then every 6 months for 2 years from the date of study registration.

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.
