Genetic Toxicology Studies
Genetic toxicology studies are required for any new drug in early development to identify compounds that can potentially cause mutations or chromosal damage in humans. Evaluation of genetic toxicology is also required for the registration of new chemicals for the European Union REACH (Registration, Evaluation, Authorization and Restriction of Chemical Substances) regulation.
IITRI offers the standard battery of in vitro and in vivo genetic toxicology tests required for new pharmaceuticals or for the testing of new chemicals. We have over 40 years of experience performing these studies, and our protocols meet ICH and OECD guidelines to support US EPA and FDA regulatory submissions. Each study includes dose analysis performed by our on-site bioanalytical laboratory. We also offer biodistribution studies which are critical for determining vector distribution and persistence in both target and non-target tissues.
