OBJECTIVE Sodium–glucose cotransporter 2 (SGLT-2) inhibitors have been shown to reduce liver fat in rodent models. Data regarding the effect of SGLT-2 inhibitors on human liver fat are scarce. This study examined the effect of empagliflozin (an SGLT-2 inhibitor) on liver fat in patients with type 2 diabetes and nonalcoholic fatty liver disease (NAFLD) by using MRI-derived proton density fat fraction (MRI-PDFF). RESEARCH DESIGN AND METHODS Fifty patients with type 2 diabetes and NAFLD were randomly assigned to either the empagliflozin group (standard treatment for type 2 diabetes plus empagliflozin 10 mg daily) or the control group (standard treatment without empagliflozin) for 20 weeks. Change in liver fat was measured by MRI-PDFF. Secondary outcome measures were change in alanine transaminase (ALT), aspartate transaminase (AST), and γ-glutamyl transferase (GGT) levels. RESULTS When included in the standard treatment for type 2 diabetes, empagliflozin was significantly better at reducing liver fat (mean MRI-PDFF difference between the empagliflozin and control groups −4.0%; P < 0.0001). Compared with baseline, significant reduction was found in the end-of-treatment MRI-PDFF for the empagliflozin group (16.2% to 11.3%; P < 0.0001) and a nonsignificant change was found in the control group (16.4% to 15.5%; P = 0.057). The two groups showed a significant difference for change in serum ALT level (P = 0.005) and nonsignificant differences for AST (P = 0.212) and GGT (P = 0.057) le...
