Licensing of biosimilars in Europe

Home/Guidelines | Posted 02/07/2010 post-comment0 Post your comment

How is licensing of biosimilars actually being applied in Europe? This was the question broached in a paper by Dr Christian Schneider – Chairman of both the Committee for Advanced Therapies and Biosimilar Medicinal Products Working Party and Co-opted member of the Committee for Medicinal Products for Human Use (CHMP).

Licensing of biosimilar products has been possible in Europe since a regulatory framework for similar biological medicinal products was established and there was a positive opinion by the EMA’s CHMP for the first biosimilar products (human growth hormones Omnitrope and Valtropin; brand names for somatropin).

Dr Schneider and Dr Kalinke put forward that the limited experience gained so far from biosimilar approvals has proved the following:

  • Implementation of guidelines for the development of biosimilars is possible. This was disputed earlier, particularly by innovator companies.
  • The ‘comparability exercise’ requires consideration of a wide range of aspects, including analytical and physicochemical characterisation by several methods, comparative biological assays, and comparative immunogenicity assessment, among others.
  • The use of different host cells for the biosimilar and the comparator is possible, as was shown in the case of the human growth hormone biosimilar, Valtropin (somatropin).
  • The comparator product must be approved in the EU and should not be changed during development.
  • The clinical programme for a biosimilar should establish ‘similarity’ and may therefore be reduced compared to the full clinical development required for a new drug.

The authors concluded that European guidelines introduce the general concept of biosimilars. The guidelines mention ‘any biological product’, and include complex biotech-derived medicinal products, such as immunologicals (vaccines), blood products and monoclonal antibodies (mAbs), thus opening the door for a whole new generation of biosimilars.
