Biosimilar development starts with a detailed characterization of the quality profile of the chosen reference product, to establish targets for cell line and process development, according to author Vandekerckhove and colleagues [1]. This characterization requires a careful determination of the range of variability for all relevant product quality attributes of the reference product, as well as an understanding of their relative importance, to ensure appropriate focus on the most important attributes. Following process development, similarity of the biosimilar candidate with the reference product must be demonstrated in comprehensive analytical studies. This first step in the demonstration of biosimilarity provides the most sensitive measurement of differences; and is instrumental in deciding the direction of further product development. Meticulous design of the analytical similarity programme is therefore critical to the success of biosimilar development.
