Biosimilars: implications for oncologists

Biosimilars/Research | Posted 13/07/2018

In 2015, the US Food and Drug Administration (FDA) approved its first biosimilar, filgrastim-sndz, a biosimilar of the granulocyte colony-stimulating factor filgrastim. Since then, FDA has approved four additional biosimilar tumour necrosis factor α inhibitors, and in May 2017, the Oncology Drug Advisory Committee voted in favour of approval of an epoetin alfa biosimilar. Three biosimilar monoclonal antibodies (mAbs) have been approved in the US. Although their indications are for chronic inflammatory diseases, according to authors Robert Rifkin and Susan Peck, oncologists should become familiar with these agents, because they may need to administer these drugs for patients who have concurrent chronic inflammatory conditions [1].

Biosimilars applications under review by EMA – June 2018

Biosimilars/General | Posted 06/07/2018

The European Medicines Agency (EMA) is the body responsible for approval of biosimilars within the European Union (EU). A legal framework for approving biosimilars was established in 2003. Approval of biosimilars is based on an abbreviated registration process, which allows biosimilars manufacturers to provide a reduced package of information compared to originator drugs, provided they can prove ‘similarity’ to the originator or reference drug.

Biosimilarity testing using very low doses of rituximab

Biosimilars/Research | Posted 06/07/2018

Rituximab is a chimeric, monoclonal antibody directed against CD20 expressed on B lymphocytes [1]. Currently approved indications for use are non-Hodgkin lymphomas, chronic lymphatic leukaemia, rheumatoid arthritis, granulomatosis with polyangiitis and microscopic angiitis [2]. However, rituximab is frequently used ‘off label’ for the treatment of numerous antibody-dependent autoimmune diseases [3].

Biosimilars and the role of regulatory authorities

Biosimilars/Research | Posted 22/06/2018

According to authors Hye-Na Kang and Ivana Knezevic, from the World Health Organization (WHO), market access to biosimilars can be restricted by several factors [1]:
(i) manufacturing processes may be expensive and complex
(ii) patents on the manufacturing processes of the original product may not have expired
(iii) biosimilar manufacturers may have limited access to data on the original product
(iv) appropriate regulatory frameworks may not be in place
(v) government policies on switching to biosimilars, pricing and reimbursement may be lacking.

Efficacy, safety and immunogenicity of adalimumab biosimilar BI 695501

Biosimilars/Research | Posted 22/06/2018

Adalimumab is the most commonly prescribed biological and is approved for rheumatoid arthritis as well as psoriasis, psoriatic arthritis, along with Crohn’s and ulcerative colitis. Its patent life terminated in 2016 in the US [1]. However, in the US AbbVie has stated that, although the composition of matter patent covering Humira expired in December 2016, non-composition of matter patents covering Humira expire no earlier than 2022. The company has therefore made settlement agreements with Amgen and Samsung Bioepis, delaying the launch of biosimilars until January 2023 [2, 3].

Spanish associations sign biosimilars collaboration

Biosimilars/General | Posted 22/06/2018

The Spanish Association of Biosimilar Medicines (BioSim) announced on 21 March 2018 that BioSim and the Federation of Spanish Medical Scientific Associations (FACME) have signed a collaboration agreement that includes the creation of a joint working group to share up-to-date information on biosimilars.

Life cycle and regulatory evaluation of biosimilars

Biosimilars/Research | Posted 15/06/2018

The life cycle of a biosimilar, like any biological, starts with research and development, then manufacturing, and is followed by regulatory evaluation of quality, safety and efficacy for both licensing and post-licensing oversight. Once licensed, a biosimilar is an individual product and post-licensing evaluation should be carried out like any other biological. The only difference for a biosimilar is that regulatory approval relies on the safety and efficacy data and knowledge gained during the development and licensing of an originator, or reference product.
