Meet the Experts Transporter Conference Webinar - Endogenous Biomarkers to Detect Transporter Drug-drug Interactions: the Recent Updates

Meet the Experts Transporter Webinar - Endogenous Biomarkers to Detect Transporter Drug-drug Interactions: the Recent Updates


Like much of the world, we are limiting our travel and putting face-to-face meetings on hold as a result of the COVID-19 pandemic. The pace of scientific progress continues however, and with it the need for discourse and debate. Since taking the difficult decision to postpone our Meet the Experts Transporter Conference at the start of the year, we have received a significant level of interest from our colleagues in the transporter field for an alternative venue in which to showcase the latest in transporter research. We are therefore delighted to announce the start of the SOLVO Biotechnology Meet the Experts Transporter Webinar Series!

He is the associate editor/editorial board member of top ranking DMPK journals including DMD, BDD, JPS and Frontier Pharmacology etc. He is a patent inventor and the author of a book, book chapters and over 160 original publications.


Endogenous Biomarkers to Detect Transporter Drug-drug Interactions: the Recent Updates

Current regulatory guidances use in vitro transporter inhibition data to determine if clinical DDI trials are necessary. In order to reduce the number of false negatives, the approaches are conservative, which result in an increased number of clinical DDI trials. The endogenous transporter DDI biomarkers are increasingly used to resolve the limitations in using in vitro data to trigger clinical DDI trials. Since coproporphyrin-I and III were discovered as endogenous biomarkers for OATP1B inhibition, the specificity, sensitivity and analytical perspectives of the biomarkers have been well-characterized. Additionally, several endogenous metabolites are recently identified to potentially serve as DDI markers for renal transporters. The current presentation will review the emerging transporter DDI biomarkers and propose how these endogenous biomarkers can be used to assess the DDI liability for investigational drugs.
