An Observational Study of Erbitux in Patients With Metastatic Colorectal Cancer (mCRC) Refractory to Irinotecan-containing Treatment

This is an observational, non-interventional, uncontrolled, multicentric safety study in subjects with epidermal growth factor receptor (EGFR)-expressing, V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) wild-type mCRC. The study aims to collect safety data related to Erbitux treatment from a total of at least 400 mCRC subjects from about 35 institutions from the start of treatment with Erbitux until progressive disease, Erbitux-related intolerable toxicities, death, or withdrawal of Erbitux treatment (whichever occurs first).
