Cetuximab Wikipedia. Cetuximab is an epidermal growth factor receptor EGFR inhibitor used for the treatment of metastatic colorectal cancer, metastatic non small cell lung cancer and head and neck cancer. Cetuximab is a chimeric mousehuman monoclonal antibody given by intravenous infusion that is distributed under the trade name Erbitux in the U. S. and Canada by the drug company Bristol Myers Squibb and outside the U. S. and Canada by the drug company Merck KGa.

A, Bristol Myers Squibb and Eli Lilly have a co distribution. In July 2. 00. 9, the FDA approved cetuximab Erbitux for treatment of colon cancer with wild type KRAS, since it had little or no effect in colorectal tumors harboring a KRAS mutation this also applied to the EGFR antibody panitumumab. This was the first genetic test to guide treatment of cancer. In July 2. FDA approved a real time PCRcompanion diagnostic test for KRAS, the therascreen KRAS test.

Dx can be used to detect EGFR expression in the tumor material. Approximately 7. 5 of patients with metastatic colorectal cancer have an EGFR expressing tumor and are therefore considered eligible for treatment with cetuximab or panitumumab, according to FDA guidelines. Unfortunately, there is evidence that immunohistochemical EGFR receptor testing does not predict response to either cetuximab or panitumumab, so that this has been called a misleading biomarker that has nevertheless caused insurers and even health systems to deny payment for EGFR antibody treatment for patients who lack a positive tumor EGFR histochemical test. Head and neck cancereditCetuximab was approved by the FDA in March 2. SCCHN or as a single agent in patients who have had prior platinum based therapy. One of the more serious side effects of cetuximab therapy is the incidence of acne like rash. This rash rarely leads to dose reductions or termination of therapy. It is generally reversible. Further severe infusion reactions include but are not limited to fevers, chills, rigors, urticaria, itchiness, rash, hypotension, nausea, vomiting, headache, shortness of breath, wheezing, angioedema, dizziness, anaphylaxis, and cardiac arrest. Therefore, pretreatment with diphenhydramine 3.

Alpha gal allergyeditCertain geographic regions have a high rate of anaphylactic reactions to cetuximab upon the first exposure to the medication. This is unusual because exposure to the allergen must occur before the development of an allergy. Fewer than 1 of people in the northeast United States reacted, while greater than 2. The alpha gal allergy is believed to result from tick bites. Lone star ticks are native to the regions of the US where reactions occurred and were found to be the vector. Cetuximab is produced in the mouse myeloma cell line SP20 and thus contains the alpha gal oligosaccharide, as do all mammals other than primates. Mechanism of actioneditCetuximab is a chimeric mousehuman monoclonal antibody which binds to and inhibits EGFR. KRAS TestingeditThe KRAS gene encodes a small G protein on the EGFR pathway. Cetuximab and other EGFR inhibitors only work on tumors in which KRAS is not mutated. KRAS mutational analysis is commercially available from a number of laboratories. In July 2. 00. 9, the US Food and Drug Administration FDA updated the labels of two anti EGFR monoclonal antibody drugs panitumumab Vectibix and cetuximab Erbitux indicated for treatment of metastatic colorectal cancer to include information about KRAS mutations. Studies have indicated that detection of KRAS gene mutations helps physicians identify patients that are unlikely to respond to treatment with targeted EGFR inhibitors, including cetuximab and panitumumab. Accordingly, genetic testing to confirm the absence of KRAS mutations and so the presence of the KRAS wild type gene, is now clinically routine before the start of treatment with EGFR inhibitors. CRC patients with wild type KRAS tumors have been shown to benefit from a response rate of over 6. Erbitux as 1st line therapy. Around 6. CRC patients have the KRAS wild type gene.

Society and cultureeditManufactureeditEli Lilly and Company is responsible for the manufacture and supply of Erbitux in bulk form active pharmaceutical ingredient API for clinical and commercial use in the U. Neck masses in children usually fall into one of three categories developmental, inflammatoryreactive, or neoplastic. Common congenital developmental masses in the. S. and Canada, and Bristol Myers Squibb purchases the API for commercial use from Eli Lilly. Merck KGa. A manufactures Erbitux for supply in its territory outside the U. S. and Canada as well as for Japan. DistributioneditErbitux is marketed in the U. S. and Canada by Bristol Myers Squibb. Eli Lilly has the option to co promote Erbitux in the U. S. and Canada. Eli Lilly receives royalties from Bristol Myers Squibb. Outside the U. S. Canada, Erbitux is commercialized by Merck KGa. A. Eli Lilly receives royalties from Merck KGa. A.
