Digoxin In NASH (CODIN)

Summary

Nonalcoholic steatohepatitis (NASH) is a severe subtype of nonalcoholic fatty liver disease (NAFLD) which affects 1 in 3 Americans. The mainstay of treatment for NASH, which was recently renamed metabolic associated steatohepatitis (MASH), involves lifestyle interventions to promote weight loss and to treat comorbidities such as hypertension, hyperlipidemia, and diabetes mellitus. There is thus, a substantial unmet need for pharmacological therapies that are effective for treatment of NASH, especially in those with fibrosis which is the main predictor of disease progression and mortality among NASH patients. The repurposing of presently available drugs would help expedite the search for agents effective in treating NASH. The cardiac glycoside digoxin is currently used in the management of heart failure and supraventricular tachyarrhythmias. The investigators and other groups have demonstrated that digoxin protects the liver from various forms of acute and chronic liver injury. The investigators preliminary data in healthy human subject indicate an immunomodulatory effect of low dose oral digoxin with no adverse side effects. This study proposes to demonstrate the clinical benefits of digoxin on NASH and on liver fibrosis, thus supporting the repurposing of digoxin as treatment for NASH.
