Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
