A Korean Post-marketing Surveillance Study on Erbitux® in Patients With Metastatic Colorectal Cancer Refractory to Irinotecan-containing Treatment

2014-07-24 14:06:57 | BioPortfolio


This is a post marketing surveillance (PMS), prospective study to collect safety information from more than 600 subjects with epidermal growth factor receptor (EGFR)-expressing, V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) wild-type metastatic colorectal cancer (mCRC) treated with Erbitux as final evaluable cases. This PMS is requested by the Korean Regulatory Authorities because after removal of an orphan drug in Korea, there is a requirement to investigate more than 600 patients during six years, to continue monitoring and provide further information about safety and toxicity in clinical practice.


This PMS study is planned to be conducted within 6 years from the removal date of orphan drug in approximately 50 institutions in Korea.


The objective of the study is to analyse the safety and efficacy information on the use of Erbitux in the market and factors affecting its safety and efficacy.

Primary objective:

- To obtain safety information on the use of Erbitux in subjects with mCRC in terms of frequency and severity of adverse events (AEs)

Secondary objective:

- To gather clinical efficacy information of the treatment

During the PMS period, each subject's background, medical history (surgery, radiotherapy), Erbitux treatment status, concurrent medication, response evaluation, status and reason of discontinuation, all AEs (regardless of the causal relationship to Erbitux), and abnormal results of laboratory tests will be collected from the start of treatment with Erbitux until progressive disease, Erbitux-related intolerable toxicities, death, or withdrawal of Erbitux treatment (whichever occurs first). The primary endpoint, the safety evaluation will be based on all cases treated with Erbitux having received at least one dose. However, for efficacy evaluation, 12 weeks of treatment have to be applied to each subject.

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 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 10 mg/min, equivalent to 5 ml/min of Erbitux 2 mg/ml.

Medical and Biotech [MESH] Definitions

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.

A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.

Hereditary nonpolyposis colorectal neoplasms associated with other malignancies, more commonly of ovarian or uterine origin. When also associated with SEBACEOUS GLAND NEOPLASMS, it is called MUIR-TORRE SYNDROME.

A form of LYNCH SYNDROME II associated with cutaneous SEBACEOUS GLAND NEOPLASMS. Muir-Torre syndrome is also associated with other visceral malignant diseases include colorectal, endometrial, urological, and upper gastrointestinal neoplasms.

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.
