Biosimilars
Overview of research on analytical techniques in the manufacturing of biosimilars in 2012
Period: January to August 2012
Biologicals are large, complex and heterogeneous proteins with variable molecular weights, typically ranging from 18,000 to 45,000 Da. The active substance of a biological is a collection of large protein isoforms and not a single molecular entity. This fact makes manufacturing of biosimilars much more of a challenge than when producing traditional small molecule generics. It also makes it highly unlikely that the active substances between two products are identical and makes it extremely difficult to establish biopharmaceutical equivalence using analytical techniques.
Teva asks FDA to delay approval of Biogen’s MS drug
Teva Pharmaceutical Industries (Teva) has petitioned FDA not to approve Biogen Idec’s (Biogen’s) investigational pill for treatment of multiple sclerosis, BG-12 (dimethyl fumarate), citing safety concerns.
Biosimilar trastuzumab made in tobacco plants
Canada-based PlantForm have altered tobacco plants to create a biosimilar version of Roche’s breast cancer drug Herceptin (trastuzumab).
Finox submits r-FSH biosimilar application to EMA
Finox Biotech announced on 20 December 2012 that it had submitted a Marketing Authorisation Application (MAA) for its biosimilar recombinant follicle stimulating hormone (r-FSH) to EMA on 30 October 2012.
Biosimilar monoclonal antibodies on the horizon in Europe
European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use adopted the final guideline on biosimilar monoclonal antibody (mAb) and it came into effect in December 2012. The agency is also currently reviewing two marketing authorization applications (MAAs) for the biosimilar mAb infliximab.
Significance of locally produced biosimilars in Iran
Biopharmaceuticals, drugs produced by live cell culture, have a fast growing market for the treatment of a range of conditions. Despite their clinical importance, however, their cost could impose an increasing burden on either national healthcare systems or patients’ out-of-pocket expenses. The potential for reducing the costs of biopharmaceuticals is therefore attracting the attention of policymakers in the health sector.
Biosimilars applications under review by EMA – 2012 Q4
Last update: 23 August 2013
European Medicines Agency (EMA) is the body responsible for approval of biosimilars within the 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’.
CCM and Biocon make biosimilar insulin deal
Malaysia-based Chemical Company of Malaysia Berhad (CCM), announced on 14 December 2012 an agreement between its subsidiary, CCM Pharmaceuticals Sdn Bhd (CCMP), and India-based Biocon, giving CCMP exclusive licence and distribution rights to market, sell and distribute a range of insulin products in Malaysia and Brunei.
History of biosimilar monoclonal antibodies regulation in EU
Monoclonal antibodies (mAbs) are high molecular weight proteins (~150 kDa), with highly complex secondary and tertiary structures, subject to post-translational modifications, such as glycosylation.
Overview of research on manufacturing statistics and innovations of biosimilars in 2012
Period: January to August 2012
Manufacturing of biosimilars is much more challenging than producing traditional small molecule generics. Reasons for this include, in the first place, the huge costs associated with manufacturing of biosimilars, along with the fact that the risk of failure for biosimilars is significantly higher than that for small molecule generics. Secondly, biosimilars are larger and more complex molecules to manufacture. Finally, minor changes in the manufacturing process can cause significant changes in efficacy or immunogenicity.
