In June 2023, a multisociety group agreed to change the name of the disease formerly known as nonalcoholic fatty liver disease (NAFLD) to metabolic dysfunction–associated steatotic liver disease (MASLD).
In the week leading up to this, Intercept Pharmaceuticals announced that their program to develop obeticholic acid (OCA) as a first-to-market, long-awaited potential drug therapy for metabolic dysfunction–associated steatohepatitis (MASH), the more pathogenic form of this disease, was being abandoned after the US Food and Drug Administration (FDA) Gastrointestinal Drugs Advisory Committee voted against accelerated approval of the drug. This decision was made in large part owing to data showing modest efficacy coupled with multiple drug-related side effects, including worsening metabolic dysfunction.
The juxtaposition of these two events highlights what could be a fundamental change in perspective when it comes to the management of patients with MASLD and the development of therapies for this disease.
