In the European Union (EU) and other highly regulated markets, companies need to prove the similarity of proposed biosimilars to the established reference product for gaining market authorization. European regulators recommend using a stepwise approach whose first steps consist of a demonstration of similarity at the analytical level and via non-clinical studies. In addition, as a later step, clinical studies are an important source of additional evidence.
