Immunogenicity Testing: Immune Responses Affecting Drug Safety & Efficacy

Immunogenicity testing plays a crucial role in measuring the immune response elicited by large molecule drugs during biotherapeutics R&D. Given its defense mechanism, the human immune system marks large molecules as foreign invaders and mounts a subsequent reaction. Typically, this happens through the production of antibodies to remove or destroy the external elements. During the immune response, the large molecules can create even larger macromolecules that further change the immunogenicity profile of the underlying drug. In other words, the immune response triggered by the therapeutic compound or its delivery vehicle can impact the efficacy and safety of the drug. Thus, immunogenicity testing is an essential step in biopharmaceutical development.

Immunogenicity assays are complicated because of multiple interactions that occur between the drug, target, and sample matrices. Thus, careful selection of the assay format is critical for further optimization and validation. NorthEast Biolab has extensive experience in designing, validating, and optimizing immunogenicity assays according to regulatory and safety guidelines by the FDA. Our scientists systematically develop your methods for high quality and reproducible immunogenicity assays. Usually, we support clients in developing a screening assay to measure immunogenicity. This is followed by titer and confirmation assays. We also help in developing custom immunogenicity assays by checking the risk or safety profile of the antibody and the intended purpose of the drug.

Immunogenicity ADA Assays by NorthEast BioLab

Immunogenicity ADA Assays by NorthEast BioLab

Immunogenicity assays are critical in measuring an immune response against the therapeutic proteins. These tests also measure the various anti-drug antibodies (ADA) and soluble protein biomarkers. The findings from these measurements impact dose selection and the safety profile of the drug. The soluble protein biomarkers quantified during ADA assay can reveal target engagement, provide a mechanism of action, and predict the immune response related to the drug.

Samples for immunogenicity assay contain complex matrices that can create considerable interference and cause inaccuracies. Hence, scientists formulate strategies to reduce interference in immunogenicity testing and accurately support the development of therapeutic antibodies and other drug candidates.

NorthEast Biolab has 15+ years of experience in designing, optimizing, and validating ADA assays for biotech and pharma companies. We implement GLP and GCP evaluation of a new biologics in preclinical and clinical stages, respectively. Our veteran scientists have worked on a variety of immunogenicity testing assay to provide highly sensitive and selective methods.

The Basics of Bioanalysis

Bioanalysis is an essential tool in drug discovery and development for determining the concentration of drugs and their metabolites as well as various pharmacodynamics biomarkers in biological fluids. In these analyses, scientists use developed an….

Sensitive, Interefence-Free Immunogenicity Assay to Evaluate Your Therapeutics against any Anti-Drug Antibodies (ADA)

At NorthEast BioLab, we follow EMA and FDA guidelines to understand the immunogenicity exhibited by protein therapeutics. Our scientists design each ADA assay to minimize interference and have adequate sensitivity. Developing an immunogenicity assay using the above guidelines help us establish the therapeutic profile of your medication and collect predictive data for its immune response. Furthermore, this allows us to de-risk drug development and deliver a safer biotherapeutic.
