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.

Oncodesign Services, a CRO dedicated to immunogenicity testing services
Oncodesign Services is a leading CRO specializing in drug discovery and preclinical services. With over 25 years of experience, we offer bioanalytical sample analysis and immunogenicity services including platforms for method development, method transfert, method validation and sample analysis.
Our immunogenicity department offers solutions and services in immunogenicity included:
-
Production, purification and characterization of ADA positive control
..
-
ADA method development (bridging ECLA on Mesoscale Discovery® technology, ELISA)
- Screening assay / confirmation assay
- Characterization assays :
- Titration assay
- NAb assay (Cell-based assay (CBA), competitive ligand binding assay (CLBA))
- Preparation of specific reagents: Labeled drug (Biotin, ECL-Sulfo-Tag, enzyme, carrier)
- Determination of optimal experimental conditions
- Sample pre-treatment step : dissociation of complexes “drug/ADA” and/or drug extraction to improve drug tolerance of the method
-
ADA method validation
It follows current international guidelines (FDA1, EMA2) and white papers from industry (EBF3, EIP4, AAPS5), and according to IRA of the drug, and of the stage of the drug development (preclinic, clinic)
Critical parameters to be determined:
- Minimum Required Dilution (MRD)
- Sensitivity
- Drug tolerance
-
ADA sample assay from preclinical studies (GLP) and clinical trials
