New study collects data and samples to unlock mysteries of Drug-Induced liver damage
NCT ID NCT00360646
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to create a nationwide registry of 400 people who have experienced drug-induced liver injury (DILI). Researchers will collect medical information and biological samples like blood and DNA to build a resource for future studies. The goal is to better understand why some drugs cause severe liver damage in certain people. Participants must have had DILI since 1994 and be alive to join.

Inclusion Criteria: Screening Criteria To be included in the ILIAD registry, the following criteria must be satisfied: * The treating gastroenterologist / hepatologist or health care professional must believe that the subject suffered drug-induced liver injury; * The subject must be alive and the date of onset of the qualifying DILI episode must have occurred on or after January 1, 1994; * Evidence of injury that is known or suspected to be related to consumption of a drug or HDS/CAM product * The subject is taking only one of these drugs or HDS agent(s) in the period leading up to the onset of the qualifying DILI episode; * Have clinically important DILI defined in terms of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (Alk Phos). * Sufficient documentation of the event for the Causality Committee to make a determination. Exclusion Criteria: Subjects will be excluded according to the following criteria: * are not willing to have medical information and blood samples taken; * are unable to adequately give informed consent to participate in the study including the blood draw for the genetic component; * age \< 2 years old at the time of study enrollment (due to blood volume requirements). * Have a competing cause of liver injury such as hepatic ischemia that the investigator felt to be the primary reason for the observed liver injury. Known, pre-existing autoimmune hepatitis; primary biliary cirrhosis, primary sclerosing cholangitis, or other chronic biliary tract disease. Subjects are excluded due to acetaminophen hepatoxicity or liver transplant or allogeneic bone marrow transplant prior to development of drug-CAM induced liver injury.
