This guidance provides recommendations to facilitate industry’s development and validation of immune assays for assessment of the immunogenicity of therapeutic protein products during clinical trials. Specifically, this document includes guidance regarding the development and validation of screening assays, confirmatory assays, titering assays, and neutralization assays. For the purposes of this guidance, immunogenicity is defined as the propensity of the therapeutic protein product to generate immune responses to itself and to related proteins or to induce immunologically related adverse clinical events. The recommendations for assay development and validation provided in this document apply to assays for detection of anti-drug antibody(ies) (ADA).4 This guidance may also apply to some combination products on a case-by-case basis.
