The Assessment of Quality Attributes for Biosimilars: a Statistical Perspective on Current Practice and a Proposal.
AAPS Journal 2018 November 28
Establishing comparability of the originator and its biosimilar at the structural and functional level, by analyzing so-called quality attributes, is an important step in biosimilar development. The statistical assessment of quality attributes is currently in the focus of attention because both the FDA and the EMA are working on regulatory documents for advising companies on the use of statistical approaches for strengthening their comparability claim. In this paper, we first discuss "comparable" and "not comparable" settings and propose a shift away from the usual comparison of the mean values: we argue that two products can be considered comparable if the range of the originator fully covers the range of the biosimilar. We then introduce a novel statistical testing procedure (the "tail-test") and compare the operating characteristics of the proposed approach with approaches currently used in practice. In contrast to the currently used approaches, we note that our proposed methodology is compatible with the proposed understanding of comparability and has, compared to other frequently applied range-based approaches, the advantage of being a formal statistical testing procedure which controls the patient's risk and has reasonable large-sample properties.
