A biosimilar is highly similar to a licensed biological product and has no clinically meaningful differences between the biological product and the reference (originator) product in terms of safety, purity, and potency and is approved under specific regulatory approval processes. Because both the originator and the potential biosimilar are large and structurally complex proteins, biosimilars ar...

• The European Medical Agency (EMA) has issued regulatory guidelines for the development of biosimilar insulins that emphasize pharmacokinetic/pharmacodynamic studies rather than efficacy evaluations. In the United States, biosimilar insulins are currently covered by the Food and Drug Administration’s (FDA) 505(b)(2) pathway permitting evaluation of the reference product. Current and Future Per...

Regulatory approval of the first biosimilar insulin in Europe, LY2963016 insulin glargine (Abasaglar® ), in 2014 expanded the treatment options available to people with diabetes. As biosimilar insulin products come to market, it is important to recognize that insulin products are biologicals manufactured through complex biotechnology processes, and thus biosimilar insulins cannot be considered ...

In 2006, the European Medicines Agency (EMA) approved Omnitrope® as a biosimilar recombinant human growth hormone (rhGH), on the basis of comparable quality, safety, and efficacy to the reference medicine (Genotropin®, Pfizer). Data continue to be collected on the long-term efficacy of biosimilar rhGH from several on-going postapproval studies. Particular topics of interest include efficacy in ...

The similarity between a proposed biosimilar product and the reference product can be affected by many factors. This study is designed to examine whether any subtle difference in the distribution of the charge variants of an Avastin biosimilar can affect its in vitro potency and in vivo PK. Here, the acidic, basic and main peak fractions of a biosimilar product were isolated using high-performa...

Introduction: Introducing biosimilar infliximab for the treatment in rheumatology (rheumatoid arthritis and ankylosing spondylitis) and inflammatory bowel disease (Crohn's disease and ulcerative colitis) may reduce treatment costs associated with biologics. This study aimed to investigate the budget impact of adopting biosimilar infliximab in five European countries, considering that the budget...

PURPOSE To evaluate the efficacy and safety of the biosimilar infliximab in adult patients with inflammatory arthritis switched from reference product in our center. PATIENTS AND METHODS In April 2014, patients attending our rheumatology service for infliximab infusions were switched from reference product to the biosimilar infliximab following consent and hospital approval. RESULTS Around ...

Biosimilar agents are approximate copies of branded biologic therapies. Since the first biosimilar was authorized in the European Union in 2006, fifteen additional agents have been approved by the European Medicines Agency, including two biosimilar monoclonal antibodies (mAbs). Biosimilar mAbs represent a distinct class given their large molecular size, complex protein structure, and post-trans...

INTRODUCTION Febrile neutropenia (FN) is a serious and frequent complication of cytotoxic chemotherapy. Biosimilar filgrastim (Nivestim™, Hospira Inc, A Pfizer Company, Lake Forest, IL, USA) is a granulocyte-colony stimulating factor licensed for the treatment of neutropenia and FN induced by myelosuppressive chemotherapy. The primary goal of this VENICE study (ClinicalTrials.gov identifier, NC...

Biosimilar insulins are likely to enter clinical practice in Europe in the near future. It is important that clinicians are familiar with and understand the concept of biosimilarity and how a biosimilar drug may differ from its reference product. The present article provides an overview of biosimilars, the European regulatory requirements for biosimilars and safety issues. It also summarizes th...
