Clinical data requirements for biosimilars in the EU: efficacy comparability

Biosimilars/Research | Posted 08/11/2019

The European Medicines Agency (EMA) uses a totality of evidence approach in its regulatory review process for biosimilar approval. As part of this, the biosimilar should demonstrate that it does not have clinically meaningful differences from the originator biological, based on comparative clinical studies.

Switching from originator to biosimilar epoetins appears to be effective and safe

Biosimilars/Research | Posted 04/10/2019

Switching between biological drugs during pharmacological treatment leads prescribers and patients to ask themselves the question: ‘Will it be safe?’. In particular, when switching from an originator to a biosimilar, the belief that this choice is shaped by economic reasons feeds suspicions and controversies.

Switching from originator infliximab to CT-P13: real-world data with 24 months of follow up

Biosimilars/Research | Posted 27/09/2019

A prospective observational study with moderate-to-severe Crohn’s disease (CD) and ulcerative colitis (UC) patients switched from infliximab to CT-P13 treatment was carried out at Hospital Universitario Virgen Macarena, Seville, Spain, and reviewed up to 24 months. The primary endpoint was to analyse the loss of response to infliximab after switching. A loss of response was considered as the Harvey–Bradshaw (HB) index >4 for CD, partial Mayo score (PMS) >2 for UC, steroid use or surgery related to the activity of the disease and/or infliximab dose increase during the follow up.

Screening protein surface biosimilarity of rituximab using aptamers

Biosimilars/Research | Posted 20/09/2019

Among the many features needed to prove sufficient biosimilarity to a licensed drug produced in living organisms, is coherency of the three-dimensional structure. The integrity thereof is vital for the efficacy and safety of a biopharmaceutical, and even small and local structural changes may result in loss of function or cause undesired side effects for the patients. Reliable assessment of the detailed three-dimensional structure, however, requires laborious analytical methods like Nuclear Magnetic Resonance (NMR) or X-ray crystallography. Another option, epitope characterization using antibodies specific for the target biologicals, is restricted by the availability of appropriate, well-characterized antibody panels and typically involves animal experiments.

Extensive characterization of biosimilars: a pegylated filgrastim study

Biosimilars/Research | Posted 16/08/2019

Pegfilgrastim, is a 38 kDa, pegylated form of filgrastim, with a 20 kDa monomethoxypolyethylene glycol (mPEG) molecule covalently bound to the N-terminal methionyl residue of filgrastim developed by Amgen. Attachment of the mPEG-moiety enables a longer half-life, that enables only once-per-cycle administration for the management of chemotherapy-induced neutropenia. This results in a much simpler treatment regime for patients. The biosimilar version of pegfilgrastim developed by Intas Pharmaceuticals, and marketed by Accord Healthcare under the brand name Pelgraz, is one of the first pegfilgrastim biosimilars to be approved for market authorization in the European Union (EU) [1].

How local policy measures and practices influence originator biological and biosimilar market dynamics in Sweden

Biosimilars/Research | Posted 21/06/2019

The licensing of biologicals, including biosimilars, in Europe is centralized via the European Medicines Agency (EMA). Subsequently, individual European Member States are responsible for pricing, reimbursement and policies on market entry and use of medicines. This decentralized responsibility results in diverging approaches towards market entry and uptake of biosimilars and contributes to variation in the use of biosimilars across European countries, and even within countries differences in biosimilar uptake levels exist. The latter is the case for the 21 counties of Sweden, implying that decisions taken by their county councils play a role in market access of biosimilars, alongside policy measures and incentives provided at the national level.
