To Evaluate the Effect of Nesinaact on Non-alcoholic Steatohepatitis Through MRI and Liver Fibroscan in Patients With Type 2 Diabetes

This study was designed to evaluate the effect of Nesinaact on non-alcoholic steatohepatitis through magnetic resonance imaging (MRI)-based proton density-fat fraction (MRI-PDFF) and liver fibroscan in patients with type 2 diabetes. This is a prospective, open-label, single-arm, single-center clinical Study. After 24 weeks of Nesinaact 25/15 (Alogliptin benzoate 25mg, pioglitazone hydrochloride 15mg) treatment, the improvement of parameters estimated by MRI and liver fibroscan will be estimated.
