SMALL MOLECULE

Our NDA-enabling portfolio of preclinical drug discovery and drug development services includes rigorous and definitive assays in all areas of ADMET, often triggered by specific requests from a regulatory agency. We have an extensive history of performing late-stage studies to support successful NDA submissions, mainly related to toxicology or drug-drug interactions. Our philosophy of utilizing the same validated in vitro test systems across the board, with different levels of rigor, ensures that results will be consistent from screening through NDA.
