The need to strengthen the post-approval regulation of biological products stems from their increasing role in the treatment of serious human diseases. Until recently, there were open questions on the classification of changes and supporting data necessary to confirm the comparability of a biological medicinal product before and after any changes, as well as on the procedures and deadlines for the submission and approval of variations. In October 2017 the WHO Expert Committee on Biological Standardisation developed and published the «Guidelines on procedures and data requirements for changes to approved biotherapeutic products». The WHO recommendations are primarily aimed at resolving the complexities and current problems in the global life cycle management of biotherapeutic products. Guidelines suggest approaches that ensure continued quality, efficacy, and safety of this group of products, as well as continuity in supply and access. The purpose of this paper was to analyse the WHO recommendations on post-approval changes to biotherapeutic products in order to develop harmonised approaches to the assessment of post-approval changes to biological medicinal products in the Russian Federation. The categories of quality changes, supporting data, conditions to be fulfilled, procedures and deadlines set forth in this paper can serve as a basis for further improvement of the national regulatory and methodological framework.
