5. Study Description
Brief Summary
The purpose of this study is to investigate the response rate of cetuximab plus irinotecan every 2 weeks in patients harboring wild-type KRAS with and without detectable EGFR-expressing metastatic CRC after failure to irinotecan in an exploratory manner.
Detailed Description
Twenty patients with positive-EGFR results and 20 patients with negative-EGFR results will be accrued in this study. All patients should have wild-type KRAS.
