Immunogenicity CRO services to assess drug safety and efficacy in preclinical studies


Immunogenicity is a major item in the Drug Development process. The study of immunogenicity generates data on the efficacy and the safety of the drug candidate behavior, enabling the translation of findings from the laboratory to the clinic.

CRO services can conduct comprehensive immunogenicity testing to accelerate your research programs.

Why are immunogenicity data important? 

Immunogenicity risk assessment (IRA) needs to be controlled all along the development of the drug, from target identification to clinical phase.

Immunogenicity refers to the ability of novel therapeutics to stimulate an immune response in the human or animal body, specifically, the development of antidrug antibodies (ADAs).  The neutralizing fraction of ADA (NAb) may affect the efficacy of product and potentially threaten patient safety.

Measuring immunogenicity is, however, a complex process…

The measurement of adverse immune reactions is complex as it depends on many drug, target, patient and disease specific aspects. Anti-drug antibodies (ADA) are detected with qualitative methods based on a tier based approach (i.e. screening / confirmation / characterization of ADA) in samples from preclinical studies (GLP)and clinical trials.

For that, it is necessary to design:

  • Administration protocols
  • Collect protocols (ADA, PK/TK)
  • Interpretation of results
