Abstract

Clinical evaluation of comparative immunogenicity represents an important component of the European Union regulatory review process for candidate biosimilar products. The clinical evaluation is part of a multidisciplinary review that cross-refers to product quality attributes as well as preclinical and ongoing risk management considerations. Results from the monitoring of anti-drug antibody formation in relevant populations treated for an adequate period of time are interpreted in relation to clinically relevant endpoints, including pharmacokinetics, pharmacodynamics, efficacy, and safety parameters. The experience gained during the 10-year period following the implementation of the European Union biosimilars pathway indicates that a suitably cautious approach was applied, insofar as no immunogenicity-related issues have emerged for the approved applications of the different biosimilar products.
