An anti-drug antibody refers to an antibody binding to the idiotope of another antibody, generally an antibody drug. An idiotope corresponds to a region within the Fv region binding to the paratope of a different antibody.
Anti-idiotypic antibodies against therapeutic antibodies can be generated for various applications such as PK/PD studies or immunogenicity studies. They can be divided into 3 different types and are particularly useful for the quantification of specific antibody drugs:

Anti-drug antibodies are commonly used for detection and quantification of therapeutic antibodies during the drug development process. One of the major challenges encountered in this type of measurement comes from the complex composition of the serum as the human serum is composed of a high excess of human antibodies. Thus, there is a high degree of similarity between the endogenous human antibodies and the humanized or fully human antibody drug. Therefore, highly specific and highly sensitive antibodies are a prerequisite to perform reliable pharmacokinetic and immunogenicity assays.
Pharmacokinetic assays are commonly based on ligand binding assays for the quantification of various forms of monoclonal antibody drugs (free, bound, total). The accuracy of the designed assay is of primary importance for the assessment of the exposure-response relationship in order to determine the optimal dose and safety parameters.
Generation of anti-idiotypic antibodies offers a more accurate quantification in comparison with the use of generic assays based on less specific antibodies such as light-chain antibodies. The latter can be used at the preclinical phase as a first total mAb approximation but could no longer be used on clinical samples.
Several ELISA assays exploiting anti-drug antibodies are commonly used to quantify the different forms of therapeutic antibodies in pharmacokinetic assays. Here are some examples of the design commonly used.
Immunogenicity represents the ability of an antibody drug to generate an immune response. When the immune response is directed against a therapeutic antibody (antibody-drug antibodies, ADA), it can dramatically impact the antibody drug efficacy and safety. Thanks to their ability to bind specifically to an antibody drug, anti-drug antibodies and anti-idiotypic antibodies share a common property. Thus, polyclonal as well as monoclonal anti-idiotypic antibodies can be used as a reference for immunogenicity assays.
