The International Transporter Consortium (ITC) encourages dialogue in all sectors of transporter research to solidify our present understanding, challenge our current thinking, and position ourselves to better address the complex and critical issues related to transporters in drug development.

ITC’s goals are as follows:

Consortium History

October 2008: First workshop held; sponsored by U.S. Food and Drug Administration and Critical Path Initiative
March 2012: Second workshop focused on the status of transporters with emphasis on the role of multiple transporters in pharmaceutical research and development with a specific focus on potential clinical impact 


ITC published its recommendations from the second workshop in the November 2012 issue of Clinical Pharmacology & Therapeutics. This manuscript provides the updated ITC transporter figure, a high-level summary of ITC2 recommendations, and a description of the upcoming series of white papers.
