An experimental drug aimed at treating a common liver disease showed promising results and potential problems in a multicenter clinical trial funded by the National Institutes of Health. The FLINT study found that people with nonalcoholic steatohepatitis (NASH) who took obeticholic acid (OCA) had improved liver health during that period, including decreased inflammation and fat in the liver and decreased body weight versus people receiving a placebo. OCA was also associated with increases in itching and total cholesterol.
