Should anti-drug antibodies be measured in animal studies?
Measurement of anti-drug antibodies in animal studies may be needed as part of repeated dose toxicity studies, in order to aid in the interpretation of these studies (as discussed in “ICH S6 (R1) Harmonized Tripartite Guideline on preclinical safety evaluation of biotechnology-derived pharmaceuticals.”).
Should anti-drug antibody response be compared to a reference product?
In the development of similar biological medicinal products (biosimilars), the comparison of the anti-drug antibody response to the biosimilar and the reference product in an animal model is not recommended as part of the biosimilar comparability exercise, due to the low predictivity for the immunogenicity potential in humans.
How do anti-drug antibodies affect pharmacokinetic properties?
The resulting anti-drug antibodies modify the pharmacoki-netic and pharmacodynamic properties of the drug and, byblocking the drug-target interac-tion, reduce the effects of the treatment. Anti-drug antibodies may also increase the risk of hypersensitivity reactions by the formation of immune complexes.
What are the different types of antidrug antibodies (ADA) detection immunoassay formats?
Anti‐drug antibodies (ADA) detection immunoassay formats. (a,b) Direct immunoassay methods. Drug ‘D’ is (a) coated on the assay plate directly or (b) captured on a streptavidin‐coated plate via a biotin linker (orange triangle). Test sample is added and ADA (Y‐shaped red symbol) are captured by platebound drug.
