NASH: A Disease with No FDA-Approved Treatment

Nonalcoholic steatohepatitis (NASH) is a more advanced form of nonalcoholic fatty liver disease (NAFLD) that can lead to serious complications.

NASH Patient with Liver Fibrosis

NASH is a leading cause of liver related mortality and an increasing burden on healthcare systems globally.

NASH is a leading cause of liver related mortality and an increasing burden on healthcare systems globally.1 Additionally, patients with NASH, especially those with more advanced metabolic risk factors (hypertension, concomitant type 2 diabetes), are at increased risk for adverse cardiovascular events and increased morbidity and mortality.2

Once NASH progresses to significant liver fibrosis (consistent with F2/F3) the risk of adverse liver outcomes increases dramatically:

  • The risk of liver related mortality and other liver related events (e.g. transplant) increases meaningfully in patients with increasing degrees of liver fibrosis. Patients with significant liver fibrosis have an approximately 10-17X increased risk of liver-related mortality versus patients without liver fibrosis.3
  • NASH is rapidly becoming the leading cause of liver transplantation in the U.S.4
  • People with NASH have an increased risk of heart attack, stroke and death.2,5

There are currently no FDA-approved therapies available for the treatment of NASH.

We are conducting a late-stage clinical development program to evaluate the benefit of resmetirom for patients with NASH.

Despite its significant clinical impact, there is no FDA-approved treatment for NASH.
