Biosimilars
Answers to questions about anti-TNF biosimilars
While the potential pharmacoeconomic benefits of cost-effective biosimilars seem clear, several issues have been raised regarding, for example, the definition of biosimilarity and the validity of indication extrapolation, as well as the ‘switchability’ and relative immunogenicity of biosimilars and their reference drugs. In a review by Isaacs and co-authors, these questions with reference to CT-P13 (Remsima, Inflectra), a biosimilar of the anti-tumour necrosis factor (TNF) monoclonal antibody infliximab (Remicade) were discussed [1].
FDA accepts application for etanercept biosimilar
Sandoz, the generics division of Novartis, announced on 2 October 2015 that the US Food and Drug Administration (FDA) had accepted its application for its etanercept biosimilar (GP2015).
Another infliximab switching trial started
In The Netherlands another study has been initiated into the effects of switching patients from originator infliximab to biosimilar infliximab.
Biosimilar epoetin-α as effective as originator in anaemia treatment
A study by researchers in Italy has concluded that biosimilar epoetin‑α appears to be comparable to originator epoetin‑α plus liposomal iron (Sideral), vitamin B12 and folates in terms of efficacy and safety for the treatment of refractory anaemia [1].
Biosimilar etanercept safe and effective
In a study funded by Samsung Bioepis (a Biogen and Samsung joint venture), their candidate etanercept biosimilar (SB4) has been found to be safe and well tolerated and to be equivalent in terms of efficacy compared to Enbrel (etanercept) in patients with rheumatoid arthritis (RA) [1].
Positive phase III results for bevacizumab biosimilar
Results of a phase III trial have demonstrated the similarity of partners Amgen and Allergan’s biosimilar bevacizumab candidate (ABP 215) to Avastin in patients with advanced non-small cell lung cancer (NSCLC).
Biosimilar production in Malaysia
Malaysian biotech firm Inno Bio Ventures has announced the signing of a memorandum of understanding (MoU) with Iranian firm Aryogen Biopharma. The agreement will lead to the production of the first Malaysian-made biosimilars for the local and regional market.
Dutch medicines agency aims to clarify biosimilars confusion
The Dutch Medicines Evaluation Board (MEB) has further clarified its position on biosimilars since its last update in March 2015. The MEB had previously raised concerns among patient groups and professional organizations with the announcement that biosimilars had no relevant differences to originators.
Biosimilar insulin launched in the UK
Eli Lilly and Boehringer Ingelheim announced on 26 August 2015 the UK launch of their biosimilar insulin glargine, Abasaglar.
Pharmacoeconomic modelling of biosimilars in the US
There are many challenges and uncertainties associated with the introduction of biosimilars to the US. To try and address these, authors from the Partnership for Health Analytic Research developed a conceptual framework to provide guidance in modelling biosimilars in the US setting [1].
