PG - 36 LID - 10.1208/s12248-020-0413-z [doi] AB - Biologics can potentially induce unwanted immune responses, leading to formation of antidrug antibodies (ADA) of various affinity, isotypes, and subclasses. Among them, antigen and drug-specific immunoglobulin E (IgE) antibodies have been reported to have potential correlation with hypersensitivity and anaphylaxis in particular. Recent regulatory guidance on immunogenicity testing has recommended the measurement of antigen-specific IgE antibodies for biologics with a reported high risk of anaphylaxis using assays with sensitivities in the high pg/mL to low ng/mL range. Nevertheless, IgE ADA remains challenging to detect due to their being the least abundant isotype in blood serum samples and the potential for interference in the bioanalytical methods due to high levels of endogenous immunoglobulin G (IgG) and immunoglobulin M (IgM) ADA, not to mention the nonspecific total serum IgE antibodies. Another challenge in developing IgE ADA assays is the need to create a surrogate drug-specific IgE antibody positive control to monitor the performance of the assay for the intended use. In this case study, utilizing a human IgE antidrug antibody positive control and a human IgE receptor as capture, an enzyme-linked immunosorbent assay (ELISA) method was developed for the measurement of IgE ADA, meeting the regulatory expectations, with excellent assay sensitivity, selectivity, specificity, and tolerance towards potential interference in serum samples. This assay format could be readily adapted and implemented to assess drug-specific IgE antibodies in the event of drug-related anaphylaxis in clinical and in nonclinical development programs.
