BACKGROUND The approval of the first biosimilar in the United States has placed increased pressure on the FDA to provide guidance on the naming convention that will be assigned to current and future biosimilars. The release of the FDA draft guidance on nonproprietary naming of biosimilars in August 2015 established a naming convention for all biologic products, including biosimilars. However, t...

BACKGROUND During clinical trials, researchers rarely question nominal doses specified on labels of investigational products, overlooking the potential for inaccuracies that may result when calculating pharmacokinetic and pharmacodynamic parameters. This study evaluated the disparity between nominal doses and the doses actually administered in two Phase I trials of a biosimilar drug. METHODS ...

Biosimilars are follow-up versions of innovative medicines with proved high similarity to the reference product. There may be some minor differences in clinically inactive components of a molecule which can be clinically significant, but they do not substantially affect the high resemblance to the original drug in their safety and potency. Introduction of the biosimilars brings hope to reduce t...

Etanercept is a recombinant fusion protein approved for the treatment of TNF-α mediated diseases such as rheumatoid arthritis (RA), psoriasis, psoriatic arthritis, and ankylosing spondylitis. Herein, we present an evaluation of the physicochemical and biological properties of a biosimilar etanercept and its reference product followed by a clinical study in patients diagnosed with RA intended to...

Biologic therapy, such as those that target tumor necrosis factor (TNF) signaling, has proven to be an efficacious method of treatment for patients with inflammatory bowel disease (IBD) with regards to symptom management and mucosal healing. However, the rising prevalence of IBD worldwide and the ever-increasing burden of biologic pharmaceuticals in the health care industry is alarming for insu...

A biosimilar drug is defined in the US Food and Drug Administration (FDA) guidance document as a biopharmaceutical that is highly similar to an already licensed biologic product (referred to as the reference product) notwithstanding minor differences in clinically inactive components and for which there are no clinically meaningful differences in purity, potency, and safety between the two prod...

T he U.S. Food and Drug Administration (FDA) is expected to release final regulations outlining lower-cost approval pathway requirements for so-called biosimilar drugs. The introduction of biosimilars is expected to reduce prices, albeit

Limited access for high-quality biologics due to cost of treatment constitutes an unmet medical need in the United States (US) and other regions of the world. The term "biosimilar" is used to designate a follow-on biologic that meets extremely high standards for comparability or similarity to the originator biologic drug that is approved for use in the same indications. Use of biosimilar produc...

624 mAbs Volume 5 Issue 5 Dear Dr Reichert, The emerging area of biosimilars to large complex protein molecules such as antibodies brings with it many challenges, both for biotechnology manufacturers as well as regulatory authorities. We read with interest your recent article by Tan et al. that, for us, highlighted these challenges previously referred to as a knowledge gap between the innovator...

Biosimilar insulins are approved copies of insulins outside patent protection. Advantages may include greater market competition and potential cost reduction, but clinicians and users lack a clear perspective on 'biosimilarity' for insulins. The manufacturing processes for biosimilar insulins are manufacturer-specific and, although these are reviewed by regulators there are few public data avai...
