Immunogenicity

Three major concerns are associated with drug immunogenicity:

  • drug allergenicity or anaphylactic shock
  • cross-priming of auto-immune responses
  • the ability of anti-drug immune responses to alter pharmacokinetics, pharmacodynamics or other biological activities of the drug

Immunogenicity testing is recommended for biopharmaceuticals by the EMA and FDA  and by the “International Conference on Harmonization” (ICH Q6B).

Studies on immunogenicity of therapeutic peptides, proteins or antibodies are often needed to determine bioequivalence and for generics to determine biosimilarity or biocomparability.

Using a custom approach we can develop and validate specific sandwich ELISA for measuring total and specific immunoglobulins. We evaluate the assay cut-off point, sensitivity, intra-/inter-assay variability and sample stability.
