Safety Assessment Services

With 130 animal rooms and occupying 18,000 m² of laboratory space, Charles River’s AAALAC accredited facility in Lyon, France, conducts in vivo safety assessment by both routine and non-standard routes of administration. Our Lyon site is home to both Research, Models & Services (RMS) and Safety Assessment (SA), offering a unique advantage in the CRO industry in animal supplying for DART and juvenile studies.

For your drug development, the scientific advisory services group (SAS) will help with specific questions on your study design and drug development project. An innovation group is available to listen to your needs and anticipate developments in our industry. In addition, the Lyon site is preparing to launch BSL2 capabilities specific to rodent safety assessment studies.

General Toxicology Acute to Chronic Toxicology

Offering the full range of standard rodent and nonrodent models, the expert toxicologists at our Lyon facility design and conduct both standalone studies and expertise as well as full development programs. Standard study designs, such as single dose, sub chronic, chronic, and carcinogenicity (including TgRasH2) are available.

Our Lyon site uses the following non-standard routes:

    •     Continuous/intermittent intravenous infusion, using ambulatory pumps
    •     Subcutaneous infusion
    •     Intravitreal
    •     Intrathecal/intracerebral
    •     Intraarticular
    •     Intranasal
    •     Intravesical
    •     Intradermal and dermal, including wound healing


The staff at our Lyon site has specific and extensive experience in:

Intravenous Infusion

Charles River offers both intermittent and continuous infusion models for both rodent and nonrodent species. Our vast infusion experience and cutting-edge infusion technology ensure high quality to your most complex and challenging study designs. Our experts in surgery continuously improve their techniques to meet your requirements. Thanks to our experience, we can conduct continuous and intermittent intravenous infusion from rat, in reproductive toxicology studies, in pre- and post-juvenile studies.

Safety Pharmacology

Safety pharmacology programs can help advance drug development by investigating the potential undesirable effects of a compound on physiological functions in relation to exposure in the therapeutic range and above. As every compound is unique, it takes specialized knowledge of regulatory guidance to develop the most appropriate drug safety program.

The scientists at our facility in Lyon can customize your in vivo safety pharmacology study to address both your program and compound-specific needs or include our core safety parameters in toxicology studies as an efficient means of meeting regulatory expectations.

Studies can be conducted with most routes of administration for:

    •     Central nervous system
    •     Respiratory system
    •     Cardiovascular system
    •     Renal / urinary system
    •     Gastro-intestinal system

Anatomic Pathology

Lyon’s pathology lab can perform perfusion fixation of whole animals, genomic-specific procedures at necropsy, automated embedding using our CRL harmonized organ blocking, frozen sampling/cryostat, routine H&E staining, histochemistry, and immunohistochemistry. Our pathologists are ACVP or ECVP board certified and can provide standalone expertise with oligonucleotides, BiTEs, infusion studies, vaccines, wound healing, and medical devices.

Our digital pathology platform provides whole slide scanning via AT2 and GT450 scanners with remote access through e-Slide Manager software and Deciphex (Patholytix)-enabled digital peer review of GLP studies.
Learn More

Our laboratory experts can support your toxicology study by partnering with you to develop the best translational path for your therapeutic, provide detailed regulatory expectations, and offer technical expertise in required assay formats.



Our team can provide scientific expertise on immune system function, an up-to-date knowledge of regulatory expectations, and established immunology testing. Navigate the challenges of selecting the most appropriate immune-related endpoints by leveraging our knowledge and experience. Interested in learning more about our immunology expertise?

Large Molecule Bioanalysis and Immunogenicity

The expert scientists at our Lyon site routinely develop or transfer, optimize, validate, and apply quantitative bioanalytical methods to measure drug and metabolite concentrations for samples in most biological fluid including plasma, serum, cerebrospinal fluid (CSF), urine, tissue, and unconventional matrices like ocular, muscle, and bile.
Learn More



Our comprehensive portfolio of biomarker services covers key toxicological indications and a range of therapeutic areas including oncology, inflammation, immunology, infectious disease, ocular disease, metabolism, and disease of the cardiovascular, renal, respiratory, and central nervous systems. From early discovery through clinical support, our biomarker services can help you identify novel biomarkers or select, validate, qualify, and apply known biomarkers to validate a target, prove a mechanism of action, predict therapeutic efficacy, or identify potential toxicity.
Learn More


Toxicokinetic Evaluation

The expert scientists perform PK parameter calculations and interpretation in preclinical studies (general toxicology, DART, and safety pharmacology), from bioanalytical data measured in plasma, serum or other biological fluids or tissues. Their expertise area includes small and large molecules (oligonucleotides, mAb with ADA assessment).
