Effective presentation of immunogenicity risk assessments and related data in regulatory dossiers.

The purpose of this article is to provide practical advice about how to present immunogenicity-related information in regulatory dossiers, with a particular focus on a model for an Integrated Summary of Immunogenicity to be submitted in the marketing authorization application for novel biopharmaceutical products in ICH regions (EU, USA and Japan). A format that links the analysis of potential risk factors to a justification of the methodology applied for risk evaluation and conclusions for risk mitigation is presented as a model that can be adapted according to the weight of evidence to be submitted in support of the assessment of impact on overall clinical benefit versus risk for the particular situation.
