Capturing the holistic value of biosimilars in Europe - part 1: a historical perspective

Introduction: Approved biosimilars exhibit comparable efficacy, safety, and immunogenicity to reference products. This report provides perspectives on the societal value of biosimilars within Europe and potential factors that have influenced market dynamics. Methods: An independent, self-administered survey or one-on-one in-depth interview was used to collect viewpoints about the impact of biosimilar medicines within European markets. Key insights were also sought from an expert panel of European stakeholders. Results: Survey respondents were clinicians, pharmacists, and payers from Europe (N = 103). Perceived benefits of biosimilars included increased access to innovative medicines (73% of respondents) or biologic treatments (66%). Biosimilar competition was thought to expand access to biologics (similar to 50% of respondents) or drug combinations (similar to 36%) and reduce biologic access time (34%). Key drivers of biologic access after biosimilar competition included increased biologic awareness (51%) and changes to prescribing guidelines (37%) and/or treatment paradigms (28%). The expert panel developed a market maturity framework of biosimilar adoption/opportunities comprising three stages: 'Invest,' 'Expand,' and 'Harvest.' Findings were supported by published literature. Conclusions: In Europe, the perceptions of well-informed survey/interview respondents are that biosimilars have improved patient outcomes via increased access to biologics and innovative biologic products, contributing to earlier and longer treatment of a broader population.
