Recently, WHO, EU, Japan and Canada have published guidelines on biosimilar/follow-on biologics. While there seems to be no significant difference in the general concept in these guidelines, the data to be submitted for product approval are partially different. Differences have been noted in the requirements for comparability studies on stability, prerequisites for reference product, or for the need of comparability exercise for determination of process-related impurities. In Japan, there have been many discussions about the amount and extent of data for approval of follow-on biologics. We try to clarify the scientific background and rational for regulatory pathway of biosimilar/follow-on biologics in Japan in comparison with the guidelines available from WHO, EU and Canada. In this article, we address and discuss the scientific background underlying these differences to facilitate the harmonization of follow-on biologic principles in the guidelines in future.
