Preclinical and Clinical Assays

Through our unique position as a leading provider of nonclinical and clinical analytics, our scientists are experts at assay life cycle management. This ensures that assays and testing paradigms applicable in nonclinical research are appropriately transitioned to the clinical phase, eliminating the need for costly and often difficult method transfer between laboratories.

See What Saint Nazaire Can Do for You

Located just outside of Nantes, France, our Saint-Nazaire site can perform small and large molecules and biomarkers bioanalysis to support clinical and nonclinical studies (discovery up to Phase III/IV clinical trials).
See Our Capabilities

From small to large molecules, and at any phase in development, Saint-Nazaire has the tools required to quantify and characterize drugs and metabolites in various animal and human biological matrices (e.g., plasma, whole blood, urine, excreta, bile, tears, CSF, tissues, etc.).

Large Molecules

For large molecules, bioanalysis assays are run by immunoassay or liquid chromatography-mass spectrometry (LC-MS/MS).

By Immunoassay

More than 30 ligand-binding assays using several techniques (ELISA, ECLIA, RIA, etc.) are developed each year to identify peptides, proteins, monoclonal and multifunctional antibodies, biosimilars/biobetters, or antibody-drug conjugates (ADC) in several matrices. Our 12 scientists will make sure they find a fit-for-purpose technique suited for your bioanalysis project(s).

The team at Saint-Nazaire has conducted more than 60 studies annually and analyzed more than 20,000 samples per year, so we have the capacity to take on your project and get the crucial data you need to make more confident go/no-go decisions.


The use of LC-MS/MS allows a fast development of robust and specific assays for the quantification of multiple large molecules such as peptides, proteins, monoclonal antibodies, ADC (for the antibody and the conjugate part), or oligonucleotides. The characterization of modifications, metabolites, peptide mapping is also possible for all biologics.

Our experienced team can prepare fit-for-purpose sample preparations including enzymatic digestion (e.g., trypsin) with or without immuno/affinity capture, as well as measurement in intact mode using LC-MS and HR-MS (High-resolution mass spectrometry).

Small Molecules

For your small molecule development, it is important to run the most sensitive and robust assays available. The following equipment allows us to reach those key points for analysis of active compounds and metabolites in various biological matrices (plasma, urine, tissues…):

  •    Automated and fit-for-purpose sample preparation (Protein crash, LLE, SPE…)
  •    Last generation LC-MS/MS (ABSciex API6500)
  •    High resolution mass spectrometry (HR-MS, Q-ToF)
  •    GC/MS

With more than 50 validations conducted and a capacity of more than 100,000 samples analyzed annually, Saint-Nazaire is ready to take on your bioanalytics testing.

Frequently Asked Questions (FAQs) About St Nazaire Facility on Bioanalysis, Biomarker & Immunogenicity

  • Is Charles River Laboratories Saint-Nazaire certified?

    For non-clinical safety studies, Charles River Laboratories Saint-Nazaire is GLP certified for the bioanalysis of human and veterinary drugs (OECD category 8). There are no certifications applicable to the bioanalytical work performed in support of clinical trials. Any phase conducted in Charles River Saint-Nazaire is consistent with the principles of GCP. The existing GLP quality system is applied and additional due diligence is exercised to ensure the clinical trial subjects' rights are not compromised. This includes conducting clinical bioanalysis in accordance with SOPs based on ICH E6, EU Directive 2001/20/EC and EU Directive 2005/28/EC, the EMA: Reflection paper for laboratories that perform the analysis or evaluation of clinical trial samples, and the Declaration of Helsinki: Ethical Principles for Medical Research Involving Human Subjects.

  • Which types of companies has Saint-Nazaire worked with?

    The site has already worked with different industries of all sizes, including agrochemical, pharmaceutical, biotechnology, clinical CROs, and cosmetics.

  • What quality level do I need for bioanalysis of my molecule?

    We advise and guide our clients on the best approach to be used based on the objectives of the preclinical/ clinical study together with the technical/scientific aspects. We suggest a panel of fit-for-purpose solutions from the non GLP research-grade assay to the GLP fully validated method.

  • Can I use LC-MS/MS or an immunoassay for my large molecule?

    Yes, it is possible and will be determined on a case-by-case basis with your needs and our experts.

  • Is there a lot of adaptation to do the bioanalysis from preclinical to clinical samples?

    Our teams are trained to handle studies from both preclinical and clinical stages. Scientific expertise, instruments, and GLP environment are setup for preclinical studies provide an excellent framework for clinical sample analysis, with some additional specificities: our Site Procedures include requirements about patient safety and confidentiality; we are able to store a large volume of samples at -20°C/-70°C, with appropriate tools to manage them (Watson LIMS, barcode labels…); study follow-up includes in particular sample design reconciliation, data management (data transfer specifications, transfers), management of blinded studies in addition to bioanalytical plan and report deliveries.
