The ethics of biosimilars

Biosimilars/Research | Posted 22/02/2013

Biosimilars in the EU have to undergo a strictly regulated comparability exercise against the reference medicinal product on the physicochemical, analytical, functional, non-clinical and clinical level. Only if a biosimilar is a close copy of the reference medicine will it be approved as a biosimilar [1]. Despite this fact, however, ethical issues have been raised on the use of granulocyte colony-stimulating factor (G-CSF, filgrastim) in healthy volunteers by the European Group for Blood and Marrow Transplantation (EBMT) and the World Marrow Donor Association (WMDA).

Assessment of biosimilarity under the BPCI Act

The Biologics Price Competition and Innovation (BPCI) Act defines a biosimilar as a product that is highly similar to the reference product notwithstanding minor differences in clinically inactive components and without clinically meaningful differences in terms of safety, purity, and potency. Although draft guidances issued by FDA do begin to clarify the issue, little or no discussion regarding how similar is considered highly similar is given in the BPCI Act and no criteria for assessing biosimilarity were mentioned [1].

The World Marrow Donor Association (WMDA) has expressed its position on the use of granulocyte colony-stimulating factor (G-CSF) biosimilars in healthy donors in an article published in the journal Haematologica [1].

Biosimilarity and interchangeability under the BPCI Act

Biosimilars/Research | Posted 24/01/2013

In the US, the Biologics Price Competition and Innovation (BPCI) Act was signed into law on 23 March 2010, giving FDA the authority to approve biosimilars. FDA then issued guidelines for biosimilar applications in February 2012 in the form of three draft guidance documents [1]. Despite this, there remain scientific issues regarding the assessment biosimilars and the criteria for establishing biosimilarity and interchangeability of biosimilars [2].

Biosimilar terminology confusion

Imprecise usage of the term biosimilar in the literature is an issue that has already been highlighted by EMA [1].

Pharmaceutical price regulation in Saudi Arabia: a countdown to affordable biosimilars

Biosimilars/Research | Posted 26/08/2016

The pricing of pharmaceuticals and biosimilars is generally subject to national regulatory control. Regulation is in place to ensure pharmaceutical affordability, yet enable profitability for pharmaceutical companies and facilitate innovation. A recent paper on pharmaceutical price regulation in Saudi Arabia by Alhomaidan et al. [1], charts the regulatory procedures in place, and outlines how their evolution has led to today’s regulated pricing of biosimilars.
