New York City-based Intercept Pharmaceuticals, Inc. has been informed by the National Institute of Diabetes and Digestive and Kidney Diseases that patient enrollment has started in a new clinical trial in patients with nonalcoholic steatohepatitis (NASH). The trial will evaluate Intercept’s drug candidate obeticholic acid (OCA) as a novel therapy for the disease.
NASH is a more serious form of nonalcoholic fatty liver disease and occurs in patients who drink little or no alcohol. The disease is believed to be caused by abnormal metabolism of fats and, although it is often associated with obesity and insulin resistance, it also occurs in lean individuals. NASH is associated with fibrosis (scarring) in the liver that may lead to cirrhosis, liver cancer, and death, and the disease also carries an additional mortality risk due to heart disease. NASH is now the most common liver disease in the developed world, affecting at least 3% to 5% of the U.S. population and up to 50% of patients with morbid obesity. There is currently no approved treatment for the disease.
Obeticholic acid is a potent, first-in-class farnesoid X receptor (FXR) agonist derived from the primary human bile acid, chenodeoxycholic acid, a natural endogenous FXR agonist. The FXR Ligand NASH Treatment (FLINT) trial is a double blind, placebo controlled, multi-center clinical study that will evaluate the effects of OCA compared with placebo in adult NASH patients. FLINT will enroll 280 patients at the eight U.S. centers comprising the NIDDK-sponsored NASH Clinical Research Network. The primary endpoint in the 72-week study will be determined by liver biopsy and is defined as an improvement in the NAFLD activity score with no worsening of liver fibrosis. NIDDK is providing the majority of funding for the study and is partnering with Intercept under a cooperative research and development agreement.
