The purpose of the conference is to discuss, debate, and share views among stakeholders in academia, patient groups, regulatory bodies, and the health care and pharmaceutical industries on how best to measure, evaluate, and act upon liver injury and dysfunction caused by drugs used during clinical trials.


This public conference will be held on March 23, 2016, from 8 a.m. to 6 p.m., and on March 24, 2016, from 8 a.m. to 4 p.m.

I. Background

In July 2009, FDA announced the availability of a guidance for industry entitled “Drug-Induced Liver Injury: Premarketing Clinical Evaluation” (74 FR 38035, July 30, 2009,​fdsys/​pkg/​FR-2009-07-30/​pdf/​E9-18135.pdf). First, this guidance explains that drug-induced liver injury (DILI) has been the most frequent cause Start Printed Page 2223of safety-related drug marketing withdrawals over the past 50 years and that hepatotoxicity has both limited the use of many drugs that have been approved and prevented the approval of others. Second, this guidance discusses methods of detecting DILI by periodic tests of serum enzyme activities and of bilirubin concentration and how changes in the results of these laboratory tests over time, along with symptoms and physical findings, may be used to estimate the severity of the injury. Third, this guidance suggests some “stopping rules” for interrupting drug treatment and mentions the need to obtain sufficient clinical information to assess causation. FDA published a draft of this guidance in 2006, and comments on that draft were taken into consideration when issuing the final guidance in July 2009.

II. Conference Information

The purpose of the 2016 conference is to invite participants to present their data and views and to hold an open discussion. The meetings in recent years have been attended by members of industry, regulatory bodies, and academic consultants, and the topics discussed have included several unresolved issues on which consensus was sought.

Registration: A registration fee ($650 for industry registrants and $325 for Federal government and academic registrants) will be charged to help defray the cost of renting the meeting space, providing meals and snacks, and covering the travel fees incurred by invited academic (but not government or industry) speakers, as well as any other expenses. The registration process will be handled by C-Path, an independent, nonprofit organization established in 2005 with public and private philanthropic support from the southern Arizona community, Science Foundation Arizona, and FDA.
