Pharmacodynamics

Following PK screening, discovery research typically warrants the investigation of repeatable pharmacodynamic (PD) biomarkers in multiple species. Charles River routinely conducts in vivo screening studies that generate both PK and PD endpoints.

Whether your program needs the background of genetically altered rodent models, a diet-induced phenotype or tissue-specific target engagement, we can provide the customized study designs you require.
