UK investigation suggests Merck broke competition law
A provisional statement from the UK Competitions and Markets Authority (CMA) says that Merck Sharp & Dohme (MSD) ran an anticompetitive discount scheme for anti-inflammatory drug Remicade (infliximab).
Biosimilar infliximab safe and effective in IBD
A systematic review and meta-analysis of Celltrion/Hospira’s infliximab biosimilar, Remsima/Inflectra found it to be safe and effective in the treatment of inflammatory bowel diseases (IBD) [1].
Recommendations to enhance transparency of biosimilar labels
On 6 June 2017, the European Association for Bioindustries (EuropaBio) announced that it had ‘developed recommendations for changes to the Summary of Product Characteristics (SmPC) of biosimilars that would result in an enhanced level of transparency in the label’.
FDA advisors recommend approval of Pfizer’s epoetin alfa biosimilar
US Food and Drug Administration’s (FDA) advisers have voted to recommend the approval of Pfizer’s biosimilar version of Amgen/Johnson & Johnson’s Epogen/Eprex/Procrit (epoetin alfa).
Celltrion making progress with biosimilars in China and Japan
South Korean biotechnology company Celltrion has announced advances in its biosimilar rituximab and trastuzumab programmes in China and Japan.
FDA advisory committee to review bevacizumab and trastuzumab biosimilars
The US Food and Drug Administration’s (FDA) Oncologic Drugs Advisory Committee (ODAC) announced in a Federal Register Notice on 7 June 2017 that it would be reviewing bevacizumab and trastuzumab biosimilars at its next meeting.
Infliximab biosimilar coming closer to interchangeability
Three studies presented at the Digestive Disease Week (DDW) 2017 have shown no significant differences in efficacy or safety endpoint. Two of the studies also specifically tested outcomes in patients switching from the originator infliximab product, Remicade, to the biosimilar version.
Predictive modelling of CIN prophylaxis with biosimilar filgrastim
Granulocyte colony-stimulating factors (G-CSF) stimulate white blood cell production and as such are indicated in the prophylaxis of chemotherapy-induced neutropenia (CIN) and febrile neutropenia (FN). Risk models of CIN/FN to date focus on predictors measured at the start of chemotherapy. Aapro and colleagues used a dynamic approach of CIN/FN risk modelling at the start of each cycle.
EMA accepts application for adalimumab biosimilar from Fujifilm Kyowa Kirin Biologics
Japan-based biosimilars developer Fujifilm Kyowa Kirin Biologics announced on 22 May 2017 that its application for approval for its proposed adalimumab biosimilar (FKB327) had been accepted by the European Medicines Agency (EMA).
How the FDA regulates biosimilars
The advent of recombinant DNA-technology ushered in the development of novel therapeutic protein products that have become mainstays of treatment regimens against cancer, inflammatory disorders and other serious diseases and conditions. Recombinant therapeutic proteins are typically large, complex molecules that are produced in cultured cells and manufactured using complex, multistep purification processes. Despite some of these products being ‘off-patent’ for years, they remain among the most expensive pharmaceuticals in the US and the world. One approach that governments across the globe have taken to reduce healthcare costs is to give regulatory authorities the ability to approve biologicals using an abbreviated licensing pathway that includes achieving the rigorous standard of demonstrating ‘biosimilarity’ with an already approved biological product.
