Studies using animal models to evaluate the carcinogenic potential of pharmaceuticals, although expensive and time-consuming, are a required element of the overall safety assessment of many new drug candidates.
Conventional carcinogenicity studies are 2-year rodent studies, where the animals are followed over a significant portion of their lifespan for the development of neoplastic lesions during or after exposure to the test article. However, there is growing acceptance of newer, 6-month mouse models that use fewer animals and are less costly.
IITRI offers both conventional 2-year and the more economical 6-month study options. Rodent species commonly used for the 2-year studies are Sprague Dawley and Fischer 344 rats and CD-1 mice, and the 6-month studies are typically done in transgenic rasH2 or p53+/- knockout mice.
