Toxicology

 

IITRI is a high-quality provider of preclinical toxicology and drug safety evaluation services in accordance with GLP standards, with over 40 years of experience partnering with pharmaceutical and biotechnology sponsors. We offer a full range of in vivo toxicology testing services to support submissions to the FDA and other regulatory agencies, including complete IND-enabling programs, and chemical toxicity assessment for pesticide or REACH registration.

Our toxicology team is one of the most experienced in the industry, with PhD/DABT study directors and study team technicians possessing greater than 10 years of tenure in preclinical toxicology. We provide personalized attention to your study, including ensuring your study design and execution meets regulatory and timeline requirements.

 

Acute and Chronic Toxicity Studies

IITRI offers customized acute or chronic toxicology study designs for the unique requirements of your non-GLP or GLP-compliant study goals. We also offer non-clinical toxicology studies of longer duration may be required for regulatory approval of new drugs (NDA-enabling).

  • Maximum-tolerated dose (MTD)
  • Dose-range finding study (DRF)
  • Acute, subchronic and chronic toxicity studies
  • Repeated dose toxicity studies
  • Reproductive toxicology
  • Carcinogenicity studies including 2-year and 6-month transgenic

 

Onsite Bioanalytical, Histopathology, and Clinical Pathology

As a full-service CRO, all aspects of a toxicology study are completed at IITRI’s single Chicago-based site. Our onsite support laboratories ensure seamless transfer of samples and data between study teams, and effective communication between groups for troubleshooting and coordination of activities.
