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

2014-08-27 03:15:42 | BioPortfolio


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).


Colorectal cancer is the fourth commonest form of cancer worldwide and remains a leading malignancy both in incidence and mortality. Erbitux is an immunoglobulin G1 monoclonal antibody that specifically blocks ligand binding to the EGFR with high affinity, thereby preventing downstream signal transduction and cellular responses. Erbitux enhances the effects of some common chemotherapy agents and radiotherapy and demonstrates minimal overlapping toxicities with these approaches. Erbitux in combination with other treatment modalities, has also shown efficacy in the treatment of a number of solid tumors, including mCRC, squamous cell carcinoma of the head and neck, and non-small cell lung cancer. Based on several studies conducted in the past, Erbitux has been approved for the treatment of subjects with EGFR-expressing, KRAS wild-type mCRC, as a single agent in subjects who have failed oxaliplatin-and irinotecan-based therapy and who are intolerant to irinotecan or in combination with chemotherapy. The most common Erbitux-related adverse events (AEs) are related to skin, infusion, and hypersensitivity reactions. Other side effects with Erbitux monotherapy include asthenia, dyspnoea, mucositis, nausea, pain, fever and headache.


Primary objective:

- To obtain safety information on the use of Erbitux in subjects with EGFR-expressing, KRAS wild-type mCRC in terms of frequency and severity of AEs

Secondary objective:

- To gather clinical efficacy information of the treatment

The study will primarily collect safety data related to Erbitux treatment along with the clinical efficacy information from the start of treatment with Erbitux until progressive disease, Erbitux related intolerable toxicities, death, or withdrawal of Erbitux treatment whichever occurs first. All subjects will be enrolled in the order to visit the physician after making contract and each subject will be observed for a period of 4 months in average. Erbitux will be prescribed to mCRC subjects according to the approved national label as in routine clinical practice under the supervision of an investigator experienced in the use of antineoplastic medicinal products. Prior to the first infusion, subjects will receive pre-medication with an antihistamine and a corticosteroid. The initial dose of Erbitux is 400 mg/m2 body surface area and the subsequent weekly doses are 250 mg/m2 each administered intravenously (i.v.) via in-line filtration with an infusion pump, gravity drip, or a syringe pump. The recommended infusion period for the initial dose is 120 minutes and for the subsequent weekly doses is 60 minutes with the maximum infusion rate not exceeding 5 ml/min. The observational period of this study is defined as from the first infusion of Erbitux until 28 days after the last infusion of Erbitux in each subject, regardless the reason of discontinuation of Erbitux treatment.

Medical and Biotech [MESH] Definitions

Clusters of colonic crypts that appear different from the surrounding mucosa when visualized after staining. They are of interest as putative precursors to colorectal adenomas and potential biomarkers for colorectal carcinoma.

Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause.

Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.

Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).

Tumor suppressor genes located in the 18q21-qter region of human chromosome 18. The absence of these genes is associated with the formation of colorectal cancer (DCC stands for deleted in colorectal cancer). The products of these genes show significant homology to neural cell adhesion molecules and other related cell surface glycoproteins.
