Over the past 40 years IITRI has established itself as a top-quality, full-service preclinical contract research organization (CRO) that provides the complete preclinical safety and toxicology testing programs of a large CRO, with the personalized attention of a smaller organization.

IITRI specializes in GLP toxicology and safety studies, IND-enabling programs, infectious disease vaccine and therapeutic preclinical development, and inhalation toxicology programs for the biotech, pharmaceutical, and government sponsors.

We strive to establish a true partnership with our sponsors for the planning and execution of each study.

We offer accomplished study teams, including PhD and DABT study directors and degreed technicians that are highly accessible, providing information on study progress and early results throughout the program.
