IITRI Advantage

As a midsize preclinical CRO, IITRI delivers both high-quality studies and a superior customer experience. We offer all the capabilities of a larger organization with the personalized attention that your study deserves. Our highly experienced team is dedicated to your study, providing direct communication and seamless collaboration to respond to your unique study needs. We can tackle complex problems and take on new challenges as an extension of your research team.


Dedicated to Scientific Excellence

IITRI offers a highly experienced, well-integrated team of toxicologists, analytical chemists, clinical scientists, veterinary pathologists, molecular biologists, microbiologists, Quality Assurance auditors and administrators to support preclinical drug development programs. We have been performing GLP-compliant studies since its inception in 1979, and have remained in good standing with all regulatory agencies. IITRI has a long-standing relationship with the National Cancer Institute (NCI) for preclinical toxicology studies, performing multi-year preclinical toxicology and pharmacology programs for the past 20 years, and cancer research for over 60 years.


Experienced Study Teams

Studies are overseen by experienced study directors, scientists, and technicians, with the median length of IITRI service exceeding 10 years and some senior staff with tenure over 30 years. Approximately one third of the IITRI staff hold advanced degrees (PhD, DVM, and/or MS). Toxicology Study Directors are board-certified (DABT), and support for preclinical development studies is provided by board-certified veterinary pathologists, ophthalmologists, and cardiologists. The majority of our technicians possess at least a Bachelor’s degree in a scientific field.


All Study Functions at One Facility

IITRI operates 100,000 square feet of laboratory and support space in a single location in Chicago, IL. A fully staffed clinical pathology laboratory is available onsite, as are fully equipped and staffed laboratories in analytical and bioanalytical chemistry, microbiology, biochemistry, cell biology, and molecular biology. Cross-functional study teams are formed for each study to collaborate with your team from start to finish.


Fully Accredited Facilities

The IITRI vivarium is a fully accredited facility for housing all standard rodent and non-rodent species. IITRI is a “DOD-secure” facility; both the physical security of IITRI laboratories and our facility security program are regularly reviewed by inspectors from the United States Department of Defense. Our ABSL-2 and ABSL-3+ containment suites are available for studies involving pathogenic agents and medical countermeasures (MCM), and inhalation exposure suites are available for studies in small and large animals.
