Mass spectrometry comparison of Remicade and Remsima

Biosimilars/Research | Posted 26/10/2018

The US entered the era of biosimilars in 2015 with its very first US Food and Drug Administration (FDA) approved filgrastim biosimilar Zarxio (filgrastim-sndz) [1]. Since then, FDA has approved 11 more biosimilars [2]. Nevertheless, one concern with respect to the manufacturing of biosimilars is that every company has its own proprietary manufacturing process, which could potentially lead to differences in drug properties. Consequently, the debate on how ‘similar’ the biosimilar is to the originator still remains controversial. Thus, a comprehensive but rapid characterization platform that can validate any clinically meaningful differences is required. In this regard, Pisupati et al. [3] carried out a study comparing the reference product Remicade (infliximab) with the first US monoclonal antibody (mAb) biosimilar Remsima (Europe)/Inflectra (US) by incorporating state-of-the-art mass spectrometry-based multiple-attribute monitoring (MAM).

Recommendations for biosimilars in rheumatology in the Middle East

Biosimilars/Research | Posted 28/09/2018

The increasing availability of biosimilars in Middle Eastern regions may provide an opportunity to increase the number of rheumatology patients who have access to traditionally more expensive biologicals. However, as well as a lack of real-world data on the use of biosimilars in practice, the availability of ‘intended copies*’ in the region may undermine physician confidence in prescribing legitimate biosimilars. There is a need for regional recommendations for healthcare professionals to ensure that biosimilars can be used safely.

Selection of quality attributes and test methods in biosimilarity assessment

Biosimilars/Research | Posted 21/09/2018

Biosimilar development starts with a detailed characterization of the quality profile of the chosen reference product, to establish targets for cell line and process development, according to author Vandekerckhove and colleagues [1]. This characterization requires a careful determination of the range of variability for all relevant product quality attributes of the reference product, as well as an understanding of their relative importance, to ensure appropriate focus on the most important attributes. Following process development, similarity of the biosimilar candidate with the reference product must be demonstrated in comprehensive analytical studies. This first step in the demonstration of biosimilarity provides the most sensitive measurement of differences; and is instrumental in deciding the direction of further product development. Meticulous design of the analytical similarity programme is therefore critical to the success of biosimilar development.

Biosimilars and the role of regulatory authorities

Biosimilars/Research | Posted 22/06/2018

According to authors Hye-Na Kang and Ivana Knezevic, from the World Health Organization (WHO), market access to biosimilars can be restricted by several factors [1]: 
(i)   manufacturing processes may be expensive and complex
(ii)  patents on the manufacturing processes of the original product may not have expired
(iii) biosimilar manufacturers may have limited access to data on the original product
(iv)  appropriate regulatory frameworks may not be in place
(v)   government policies on switching to biosimilars, pricing and reimbursement may be lacking.

Life cycle and regulatory evaluation of biosimilars

Biosimilars/Research | Posted 15/06/2018

The life cycle of a biosimilar, like any biological, starts with research and development, then manufacturing, and is followed by regulatory evaluation of quality, safety and efficacy for both licensing and post-licensing oversight. Once licensed, a biosimilar is an individual product and post-licensing evaluation should be carried out like any other biological. The only difference for a biosimilar is that regulatory approval relies on the safety and efficacy data and knowledge gained during the development and licensing of an originator, or reference product.

Regulating biosimilars throughout their life cycle

Biosimilars/Research | Posted 08/06/2018

A resolution to increase access to life-saving biologicals was passed in May 2014 at the Sixty-seventh World Health Assembly of the World Health Organization (WHO) [1]. However, there still exist barriers to market access for biosimilars. Authors Drs Hye-Na Kang and Ivana Knezevic, from WHO, discuss the factors that give rise to these barriers and explain the importance of regulatory oversight throughout the product life-cycle of biosimilars [2].

Trastuzumab, a recombinant humanized monoclonal antibody, acts against the tyrosine kinase human epidermal growth factor receptor 2 (HER2), which is overexpressed in up to 30% of breast cancers and gastric cancers and has been linked to poor prognosis. In the age of targeted anticancer therapy, trastuzumab is a key treatment for patients with HER2-positive (HER2+) tumours and is recommended by a number of clinical guidelines. However, the use of ‘originator’ (or reference) biologicals, such as trastuzumab, is associated with high treatment costs; an issue set to be exacerbated by an ageing population. The improved cost-effectiveness potentially provided by a biosimilar may increase patient access to treatment.

Afucosylated biosimilars: the path to matching interrelated critical quality attributes

Biosimilars/Research | Posted 20/04/2018

Advances in analytical characterization and increased understanding of drug mechanisms of action have resulted in the ability to raise the quality and safety of biosimilars by introducing critical quality attributes (CQA), which must be preserved during the manufacturing process. However, to realize these benefits, biosimilars manufacturers must develop the means to ensure these CQAs are met. For afucosylated IgG1s that rely on afucosylation content for efficacy, this has been challenging, since precisely matching both afucosylation content and biological activity has proven to be extremely difficult. In a recent paper, Chung and Zhan [1] elaborate on the underlying basis of these difficulties and highlight the work of several groups that has opened a path to directly addressing this problem.

Strategies for development and validation of neutralizing antibody assays supporting biosimilars

Biosimilars/Research | Posted 13/04/2018

A biosimilar is a biological product with equivalent safety, purity and potency as an originator reference therapeutic. As such, US Food and Drug Administration (FDA) and European Medicines Agency (EMA) guidelines have stepwise recommendations to demonstrate biosimilarity, which include immunogenicity assessment.

Biosimilar policies in Europe

Biosimilars/Research | Posted 06/04/2018

Across European countries, differences exist in biosimilar policies, e.g. pricing and reimbursement procedures, levels of education, characteristics of covered population and incentivization of stakeholders, leading to variations in uptake of biosimilars and divergences in savings from biosimilars use. Experiences from different European countries with biosimilar policies may offer useful insights into current and future uptake of biosimilars.
