Clinical Trial Summary

The primary purpose of this study is to evaluate the clinical response and safety of CMAB009 plus irinotecan versus irinotecan-only as second-line treatment after fluoropyrimidine and oxaliplatin failure in KRAS wild-type metastatic colorectal cancer patients


Clinical Trial Description

CMAB009 is a recombinant, human/mouse chimeric monoclonal antibody (mAb) that binds specifically to the extracellular domain of EGFR. It is composed of the Fv regions of a murine anti-EGFR antibody with human IgG1 heavy and k light chain constant regions and it is expressed by Chinese hamster ovary cells. It has the same amino acid sequence as cetuximab (C225, Erbitux®) , but it has slightly different abilities for glycosylation and other post-translational modifications, and it is developed by Shanghai Zhangjiang Biotechnology Limited Company and produced by Biomabs. Phase I study results suggest that CMAB009 showed well-tolerated safety profile and primary efficacy. This multicenter, open-label study was to determine whether adding CMAB009 to irinotecan increased the response rate and prolongs survival in patients with KRAS wild-type metastatic colorectal cancer (mCRC) previously treated with fluoropyrimidine and oxaliplatin. ;
