Webinar Recording - March 31 and April 6
Use of Extended Clearance Concept and PBPK Modeling in New Drug Discovery and Development: Predicting Target Tissue Exposure from In Vitro to In Vivo
Presented by Yuichi Sugiyama, PhD, RIKEN Baton Zone Program
Presented by Yuichi Sugiyama, PhD, RIKEN Baton Zone Program
Professor Sugiyama will describe the “extended clearance concept” and inform participants on how to establish a physiologically-based pharmacokinetic (PBPK) model that includes the transporter-mediated membrane transport and enzyme-mediated metabolism processes. In addition, changes in transporter (influx, efflux) function and metabolizing enzyme function affects the pharmacokinetics of drugs in the blood and the liver and, ultimately, the pharmacological and/or toxicological effects will be discussed.
Related to the above-described objectives, the webinar will also cover recent studies on the following three topics:
1. Necessity of incorporating albumin-mediated hepatic uptake mechanism to obtain better in vitro/in vivo extrapolation of hepatic clearance.
2. Substrate-dependent and/or pre-incubation time dependent Ki values of OATP1B inhibitors.
3. Use of endogenous biomarkers to facilitate subject phenotyping and DDI Prediction.
