Cell-Based Assays for Immunogenicity and Immunotoxicity
Types of assays that investigate innate immunity include uptake, digestion and presentation of biotherapeutic product by antigen presenting cells (APC) like dendritic cells in conjunction with class II HLA molecule.
This guidance provides recommendations to facilitate industry’s development and validation of assays for assessment of the immunogenicity of therapeutic protein products during clinical trials.
adequate screening and confirmatory assays to measure immune responses against a therapeutic protein is the basis of the evaluation of immunogenicity. The Applicants need to demonstrate that the ADA assays are applicable for the …
Immunogenicity Testing Services | Charles River
Our immunogenicity testing services allows you to establish the immune response to your compounds at the anti-drug antibody (ADA assay) or neutralizing antibody (nAb assay) level.
Immunoassay Methods - Assay Guidance Manual - NCBI Bookshelf
2012年5月1日 · Immunoassays are used to quantify molecules of biological interest based on the specificity and selectivity of antibody reagents generated. In HTS and lead optimization projects, assays are designed to detect molecules that are produced intracellularly or secreted in response to compounds screened.
Assessing the Immunogenicity of Biopharmaceuticals - PMC
Here, we review factors associated with immunogenicity of biopharmaceuticals, potential clinical ramifications, and current regulatory guidance for evaluating immunogenicity, and discuss methods to assess immunogenicity in non-clinical and clinical studies.
• As antibody assays improve in sensitivity we encounter detection of low level endogenous antibodies capable of binding to drug • Important to have assays sensitive to detect earliest indication of an immune response • Must be able to discriminate clinically relevant antibodies
immunogenicity assays for application during clinical testing - • Sensitivity - Sufficiently sensitive assays to detect clinically relevant levels of antibodies
Immunogenicity assessment of biotherapeutic products: An …
2015年9月1日 · Currently, the most technically feasible approach for testing a product's immunogenicity involves measuring antibodies specifically generated against the product. In clinical studies, therefore, detection and characterization of antibodies is important to understand the efficacy and safety of a BTP.
Immunogenicity / Immunotoxicity Assessment
Our Epibase® suite of immunoprofiling services and cellular assays predict and compare the immunogenicity risk potential of the biotherapeutic protein to other lead candidates and over 500 known protein sequences.
