Social trust and regional variation in the adoption of biosimilars in Italy and Germany

Introduction/Study Objectives: Adoption of biosimilars has fallen below projections, despite the vigorous implementation of economic incentives, thereby highlighting the importance of behavioural factors such as social trust. This paper analyses biosimilar adoption across provinces in Italy and Germany, which evince strong variation in social trust, and across nations in Europe. Methods: Data for 2020 biosimilar…

Structural characterization methods for biosimilars: fit-for-purpose, qualified or validated

Abstract: Detailed and accurate structural characterization of biopharmaceuticals is of paramount importance for product definition, assessment of impurities and achieving in-depth understanding of manufacturing processes. But how can we have confidence in the data obtained from characterization studies? The expectation from regulatory authorities when assessing methods for product characterization is that there will be some…

Biosimilarity is not a transitive property: implication for interchangeability, naming and pharmacovigilance

Abstract: Current regulations do not require a given biosimilar to remain similar to its reference biological over time. However, two products that were initially deemed biosimilar or interchangeable could each undergo unique patterns of drift and evolution in their manufacturing processes (divergence), ultimately resulting in two products that would be no longer biosimilar. In cases…
