Evidence on biosimilar efficacy and safety leads to ASAS/EULAR recommendation
A study of biological disease-modifying anti-rheumatic drugs (DMARDs) in patients with axial spondyloarthritis (axSpA) found no reason for physicians not to prescribe infliximab biosimilars [1].
Improving efficacy of biologicals without increasing cost
Biologicals targeting antitumour necrosis factor-α, such as Remicade (infliximab) and Humira (adalimumab), have been used for the treatment of chronic inflammatory diseases for many years. The advent of biological therapies raised significant pharmacoeconomic concerns, because the cost of biological treatment is much higher than the cost for conventional treatments, typically Euros 10.000‒20.000 per patient per year. This is an issue discussed by Professor Ann Gils from the Department of Pharmaceutical Sciences, KU Leuven, Belgium [1].
Savings to be made by using etanercept biosimilar in UK
A study of patients taking etanercept to treat rheumatoid arthritis or psoriasis in the UK has shown that there are substantial savings to be made by using the biosimilar [1].
Positive results for infliximab biosimilar in Crohn’s disease
Results of a phase III study of Celltrion’s infliximab biosimilar (Remsima; CT-P13) ‘indicate that the safety and efficacy of CT-P13 in patients with moderate-to-severe Crohn’s disease is comparable to those treated with reference infliximab’.
Candidate trastuzumab biosimilar meets equivalence requirements
Mylan and Biocon reported that their jointly developed, candidate trastuzumab biosimilar (MYL-1401O), had met equivalence requirements. The results of the study were published in the Journal of the American Medical Association (JAMA) in January 2017 [1].
Safe for IBD patients to switch to biosimilar infliximab
A UK study has shown that inflammatory bowel disease (IBD) patients can be safely switched from originator infliximab, Johnson & Johnson’s and Merck’s Remicade, to biosimilar infliximab using a managed-switching programme [1].
Regional management of biosimilars in Germany
Biosimilars offer alternative treatment options and reduce the financial burden on healthcare systems often brought about by more expensive originator drugs. Approved biosimilars of tumour necrosis factor-alpha (TNF-α) inhibitors, such as infliximab or etanercept, are managed differently across Europe. A recent study by Dr Mathias Flume assesses the prescription structure and regional uptake of these biosimilars across Germany, with focus on the Westphalia-Lippe region [1].
Positive results for Pfizer’s adalimumab biosimilar
US pharma giant, Pfizer, reported positive top-line results from a comparative study of their candidate adalimumab biosimilar (PF-06410293). The originator biological, AbbVie’s Humira (adalimumab) had sales of just over US$14 billion in 2015 [1], up 11.7% on the previous year, and retaining its place as the top grossing pharmaceutical product globally.
Positive phase III results for adalimumab biosimilar from Coherus
A phase III study of an adalimumab biosimilar (CHS‑1420) from Coherus has reported that the biosimilar is ‘similar’ to AbbVie’s Humira (adalimumab), according to the company.
Improvement in uptake of biosimilars in Spain
Author Ainhoa Aranguren Oyarzábal and colleagues from the Madrid Health Service (MHS), Spain found that there has been an increase in the uptake of biosimilars in Spain since indicators were introduced [1].
