What is hindering the uptake of biosimilars? The biggest differences between the development of a biosimilar and a generic medicine lie primarily in the preclinical and clinical stages. Unlike with classical generics, manufacturers must submit animal data and data on efficacy in patients in order to obtain marketing authorisation for a biosimilar — the exact requirements depend on the the European Medicines Slow uptake Agency (EMA) have not Although the key set any specifications selling point of a concerning the differences biosimilar is its low that are acceptable price, this may not be between the biosimilar deemed sufficiently and the original product. lower than the Differences will always originator to stimulate Huub Schell ekens Utrecht Univ be found, for instance its use. Additionally, ersity in the glycosylation in general, clinicians between two epoetin products, prefer not to switch patients from but if the clinical data show that one biologic to another.

Further, to make the biosimilar treatment traceable, substitution without the consent of the treating physician is discouraged and even made illegal in some European countries.

Another important part of the biosimilar submission process is the similarity exercise, where the biosimilar must prove to be sufficiently similar to the original product in terms of quality, safety and efficacy.
