Transporters in Drug Development: 2018 ITC Recommendations for Transporters of Emerging Clinical Importance

Clin Pharmacol Ther. 2018 Nov;104(5):890-899. doi: 10.1002/cpt.1112. Epub 2018 Aug 8.


This white paper provides updated International Transporter Consortium (ITC) recommendations on transporters that are important in drug development following the 3rd ITC workshop. New additions include prospective evaluation of organic cation transporter 1 (OCT1) and retrospective evaluation of organic anion transporting polypeptide (OATP)2B1 because of their important roles in drug absorption, disposition, and effects. For the first time, the ITC underscores the importance of transporters involved in drug-induced vitamin deficiency (THTR2) and those involved in the disposition of biomarkers of organ function (OAT2 and bile acid transporters).
