Biosimilars/Research
Improving stakeholder understanding about biosimilars
The arrival of biosimilars provides benefits for healthcare systems and patients by lowering treatment costs and improving patient access to biologicals. Despite these benefits and demonstrated comparability with the reference biological, the use of biosimilars varies across regions and remains limited in some cases. This may be partially due to a lack of knowledge and understanding among healthcare professionals and patients about biosimilars, limiting their willingness to use them.
Interchangeability, naming and pharmacovigilance of biosimilars
Results of a survey was carried out by the World Health Organization (WHO) revealed that challenges still remain when it comes to the regulatory evaluation of biosimilars [1].
Improving the understanding of biosimilars through education
The process of introducing biosimilars into clinical practice is complex and involves many stakeholders. There are different strategies that healthcare systems have adopted to incorporate biosimilars into patient care. Regulators, payers, pharmacists, and physicians need adequate knowledge in order to be effective components of this process. Previous research in the region has shown a high prevalence of lack of understanding and major safety concerns on the use of biosimilars [1].
Understanding and minimizing injection-site pain for biologicals
Biologicals have revolutionized treatment across a range of immune and inflammatory-related diseases and have had considerable impact on the health economy. Switching to a biosimilar has proven to be an effective, safe and pharmacoeconomically advantageous strategy for health systems.
Clinical evidence for interchangeability of biosimilars in the US
In the United States, the Food and Drug Administration (FDA) approval of a biosimilar is based on the ‘totality of the evidence’ from comparative analytical and functional assessments and comparative clinical (pharmacology, immunogenicity, safety and efficacy) assessments that support a conclusion of biosimilarity [1]. An approved biosimilar can also be designated as ‘interchangeable’ if it can be concluded that the biosimilar is expected to produce the ‘same clinical result as the reference product in any given patient’ and there is no increased risk in terms of safety or diminished efficacy associated with switching or alternating between the biosimilar and reference product (RP) [2]. With such designation, an interchangeable biosimilar could be substituted for its RP at the pharmacy level where state law allows [2].
How organizations worldwide are producing HTA reports for biosimilars
The vital contribution of Health Technology Assessment (HTA) is well recognized and consolidated in scientific and technological practice; however, there is still no generally accepted position on its utilization in relation to biosimilars.
Influence of local policy measures and practices on biosimilar/originator market dynamics in Germany
In Europe, the individual Member States are responsible for designing policies that regulate the market entry and use of pharmaceuticals. This decentralized approach has been found to contribute to variations in biosimilar uptake across countries, and even within countries, as was investigated for tumour necrosis factor-alfa (TNF-α) inhibitor biosimilars in Sweden [1, 2]. In Germany, biosimilar market shares are also known to vary at the regional level. This was studied by Blankart et al. for erythropoiesis-stimulating substances, filgrastim and somatropin, and variations in biosimilar market shares were partly attributed to the presence of explicit regional cost-control measures, such as quota regulations [3]. Differences in the uptake of biosimilars have also been described in Germany for the class of TNF-α inhibitors, although reasons behind this variable uptake have not been examined in detail [4].
Positive phase III results for sintilimab plus copy biological Byvasda
Chinese biopharmaceutical firm Innovent Biologics (Innovent) announced on 23 November 2020 positive results for its copy bevacizumab biological Byvasda (IBI-305) in combination with sintilimab.
More national guidance needed on biosimilars in Europe
A poster presented at the Virtual ISPOR (International Society for Pharmacoeconomics and Outcomes Research) 2020 conference outlines the importance of regulatory guidance on biosimilar medicines in Europe.
Phase I study comparing SB8 with reference bevacizumab
SB8, developed by Samsung Bioepis, was approved as a biosimilar of the reference product Avastin (bevacizumab) by the European Commission in August 2020 with the brand name of Aybintio [1]. The objective of this phase I study was to compare the pharmacokinetics, safety, tolerability and immunogenicity between SB8 and the European Union (EU) and United States (US) reference products (bevacizumab-EU and bevacizumab-US).
