Antidiabetic Drugs for Steatotic Liver Disease

To investigate the synergic therapeutic effect of thiazolidinediones and SGLT2 inhibitor on metabolic dysfunction-associated steatotic liver disease, the effect of empagliflozin 10mg, pioglitazone 15mg monotherapy and combination therapy in patients with type 2 diabetes and steatotic liver disease will be compared and analyzed.

This study was designed to include a total of 60 patients (20 per subgroup) for randomized controlled trials with prospective, open label, randomized, single-institution clinical trials.

The drug will be maintained for a total of 24 weeks. The primary endpoint is the difference of liver fat change measured by MRI-PDFF in the largest possible polygonal region of interest encompassing both lobes of the liver between three groups.
