Biomarkers in NASH Drug Development: Using Cytokeratin 18 as a Secondary Endpoint in Clinical Trials

Non-alcoholic fatty liver disease (NAFLD) is a medical condition characterized by the build-up of fat in the liver. NAFLD has a spectrum that ranges from steatosis and non-alcoholic steatohepatitis (NASH) to fibrotic NASH and cirrhosis. The prevalence of NAFLD worldwide is reported to be 20-35%, and it is strongly connected to the global epidemic of obesity and type 2 diabetes. In the United States NAFLD is the most common form of chronic liver disease and a leading indication for liver transplantation. There are currently no approved drug therapies for NAFLD or NASH, and many clinical trials are underway to address this unmet need for pharmacologic treatment options.

Liver biopsy is still considered the “gold standard” for diagnosis of NASH, and histological endpoints are currently required by the FDA for approval of NASH drugs. However, liver biopsy has many drawbacks, including sampling error, cost, risk of complications, and patient acceptability. Because of these limitations and concerns regarding liver biopsy, non-invasive biomarkers are urgently needed not just to identify subjects with NASH, but also to determine their response to novel therapeutic agents.

Markers of hepatic injury or cell death such as cytokeratin 18 (CK18 or K18) and its caspase-cleaved fragment, cCK18, have been suggested as endpoints for early clinical drug trials where histological assessments are not feasible. The M30 Apoptosense® ELISA is a specific and reliable tool to measure the concentration of cCK18 fragments. Biomarker assays used for drug development should be validated and run in a bioanalytical lab based on the context of use of the biomarker. Celerion has validated the M30 Apoptosense® ELISA for use as a secondary endpoint in NASH clinical trials.

Speakers

Naim Alkhouri, MD, Associate Professor of Medicine, Division of Gastroenterology, Adult & Pediatric Hepatologist, Liver Transplant Program, Texas Liver Institute

Dr. Alkhouri was most recently Assistant Professor of Medicine at the Cleveland Clinic Digestive Disease and Surgery Institute and Director of the Metabolic Liver Disease Clinic. He completed his medical degree at the University of Damascus in Syria before completing his internal medicine and pediatric residency at Albert Einstein Medical Center in Philadelphia. Dr. Alkhouri completed his pediatric gastroenterology, hepatology and nutrition fellowship at Cleveland Clinic and an adult transplant hepatology fellowship at the Digestive Disease and Surgery Institute, Cleveland Clinic. Dr. Alkhouri received the American College of Gastroenterology Junior Faculty Development Award to study the analysis of breath volatile organic compounds to diagnose nonalcoholic fatty liver disease. He also received the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition Fellow Research Award for his prospective evaluation of the pediatric NAFLD fibrosis index and ELF markers in children with fatty liver disease. Dr. Alkhouri has over 100 publications and presents his work at both national and international medical conferences. Dr. Alkhouri is a member of several professional organizations, including the American Association for the Study of Liver Disease, the European Association for the Study of the Liver, American College of Gastroenterology, and North American Society for Pediatric Gastroenterology, Hepatology and Nutrition. His specialty interests include nonalcoholic fatty liver disease, viral hepatitis, autoimmune hepatitis, alpha 1 antitrypsin deficiency, and liver transplantation.
