A Transporter-Based Predictive ADME Platform
DESCRIPTION (provided by applicant): Desirable drug ADME (Absorption, Disposition, Metabolism and Elimination) properties are key determinants of a drug's to safety and efficacy. Unfortunately, poor ADME and Toxicity attributes have caused more drug failur
es than any other factors. There is a pressing need for better in vitro predictive ADME tools to augment the decade-old animal studies which do not always predict clinical results in the human. The overall goal of this project is to ascertain whether in vi
vo drug ADME properties could be explained and predicted based on drugs' in vitro interactions with transporter proteins, which have been demonstrated to play significant roles in every aspect of drug ADME, along with metabolic enzyme interaction and other
drug physicochemical properties. The initial Phase I work will start with examining the roles of major liver transporters on hepatic disposition of drugs, through testing a panel of drugs against these transporters; novel in vitro models will be created f
or studying the effects of transporters-CYP interplay on hepatic drug metabolism; finally, correlations between in vitro data and clinical disposition and metabolism information will be established. Future study would extend the scope to other major tissue
s/organs with aims to explain and predict drug ADME properties and drug-drug interactions (DDI) based on in vitro transporter studies and other drug physicochemical properties. PUBLIC HEALTH RELEVANCE: Success of this project will benefit public hea
lth by facilitating discovery and development of drugs for treating various formidable diseases, particularly CNS diseases and cancer, through enhancing drug efficacy by increasing targeted drug delivery to diseased tissues, and through improving drug safe
ty by reducing adverse drug effects due to unwanted tissue distribution and drug-drug interactions.
