Immunogenicity testing is an essential step in therapeutic protein drug development process. Anti-Drug antibodies (ADA) may lead to many clinical problems including allergic reactions, altered pharmacokinetic, reduced efficacy, etc. Thus, immunogenicity testing to evaluate the ADA level induced by therapeu...
Therapeutic drug monitoring (TDM) of anti-TNF therapy is integral to the optimisation of biologics for inflammatory bowel disease (IBD).1 Following initial efficacy, secondary loss of response with sub-therapeutic drug levels is often a result of immunogenicity.2 Interpreting low drug levels in ...

Anti-drug antibodies may also increase the risk of hypersensitivity reactions by the formation of immune complexes. Furthermore, by cross-reacting with the endogenous homolog of the drug, the anti-drug antibodies might impair important physiological functions even after treatment cessation. As a ...
Positive evaluated samples can be further characterized for the presence of neutralizing antibodies against the drug. Assay formats are cell based techniques with carefully selected biological readouts (See NAb test). Please feel free to contact us if you are interested in or have any questions for...
Case Study of PK Assay Development Bispecific drugs have two different specific antigen-binding sites that can bind to two antigens or two epitopes simultaneously. Sino Biological has successfully produced competitive and non-competitive anti-idiotype antibodies against two targets of a bispecific drug....
Evolving immunogenicity assay performance expectations and a lack of harmonized anti-drug antibody validation testing and reporting tools have resulted in
Anti-BCMA antibodies work in the following ways: They belong to a class known as “antibody-drug conjugates” and work by killing the cancer cells. Belantamab mafodotin is an afucosylated monoclonal antibody that targets BCMA conjugated to the microtubule MMAF. ...
Anti-drug antibodies Incidence of ADAs Subjects were divided into four TE-ADA analysis populations depending on their maximum TE-ADA titer reached during 60 weeks of treatment. Titer subgroups included TE-ADA negative, TE-ADA low (maximum titer < 1:160), TE-ADA moderate (maximum titer ≥ 1:...
