This workshop has been organized through the efforts of the  Workshop Organizing Committee  under the leadership of the Workshop Chairs, Christopher Gibson and Lei Zhang, and was jointly sponsored by ISSX and the International Consortium for Innovation and Quality in Pharmaceutical Development (IQ). 

This workshop brings together scientists from academia, industry, and regulatory agencies in an interactive format to discuss contemporary topics in applied small molecule enzyme and transporter research. We are planning sessions covering not only laboratory and analytical challenges associated with studying enzymes and transporters in vitro, but also challenges and potential solutions/best practices in translation of in vitro ADMET data to in vivo drug disposition and clinical drug-drug interactions (DDIs). There are a mixture of presentations, including overview of the challenges in each research area, rapid-fire talks, followed by roundtable discussion sessions.

The workshop includes access to all presentation slides and recordings.

  • Session 1: Biological, Experimental and Methodological Challenges Associated with the Study of Drug Metabolizing Enzymes
