Primary Outcome Measures
NameTimeMethod
Primary end point(s): Determination of the response rate by the same imaging technique (CT/MRI) that is used consistently for each subject. Classification by modified WHO criteria. The primary analysis variable is the tumor response rate based on response assessments made by an independent radiological review committee.;Main Objective: To determine the response rate of matuzumab in combination with irinotecan background chemotherapy for EGFR-expressing metastatic colorectal cancer which developed PD while on therapy or within 4 weeks after termination of therapy with an irinotecan-based regimen.<br>;Secondary Objective: Progression free survival<br>Duration of response<br>Overall survival time<br>Safety evaluation<br>Determination of HAHA<br>Pharmacokinetics of matuzumab.
