The new world of biosimilars: what diabetologists need to know about biosimilar insulins

subject

description

Biosimilar pharmaceuticals are emerging as patent protection on the original biopharmaceutical products expires. However, biopharmaceuticals are particularly complex molecules, and biosimilar insulins present special challenges. In part this reflects their structure and chemical modification after synthesis to attain a biologically active form. Their therapeutic window is narrow and the accuracy of their dosing is highly dependent on the formulation and quality of the administration device. For these reasons, the European Medicines Agency has issued stringent guidelines that must be fulfilled in order to receive approval as a biosimilar soluble insulin. Prescribers should therefore consider issues of manufacture, protein quality, formulation, reliability of supply, and other factors that might affect efficacy, safety and tolerability when making choices regarding the selection of biosimilar products.
