Abstract AIMS/HYPOTHESIS: Glucagon-like peptide (GLP)-1-based therapies have been suggested to improve hepatic steatosis. We assessed the effects of the GLP-1 receptor agonist liraglutide and the dipeptidyl peptidase (DPP)-4 inhibitor sitagliptin on hepatic steatosis and fibrosis in patients with type 2 diabetes. METHODS: In this 12 week, parallel, randomised, placebo-controlled trial, performed at the VU University Medical Center between July 2013 and August 2015, 52 overweight patients with type 2 diabetes treated with metformin and/or sulphonylurea agent ([mean ± SD] age 62.7 ± 6.9 years, HbA1c 7.3 ± 0.7\% or 56 ± 1 mmol/mol) were allocated to once daily liraglutide 1.8 mg (n = 17), sitagliptin 100 mg (n = 18) or matching placebos (n = 17) by computer generated numbers. Both participants and researchers were blinded to group assignment. Hepatic fat content was measured using proton magnetic resonance spectroscopy (1H-MRS). Hepatic fibrosis was estimated using three validated formulae. RESULTS: One patient dropped out in the sitagliptin group owing to dizziness, but no serious adverse events occurred. At week 12, no between-group differences in hepatic steatosis were found. Liraglutide reduced steatosis by 10\% (20.9 ± 3.4\% to 18.8 ± 3.3\%), sitagliptin reduced steatosis by 12.1\% (23.9 ± 3.0\% to 21.0 ± 2.7\%) and placebo lessened it by 9.5\% (18.7 ± 2.7\% to 16.9 ± 2.7\%). Neither drug affected hepatic fibrosis scores compared with placebo. CONCLUSIONS/INTERPRETATION: Twelve-week liraglutide or sitagliptin treatment does not reduce hepatic steatosis or fibrosis in type 2 diabetes. TRIAL REGISTRATION: ClinicalTrials.gov NCT01744236 FUNDING : Funded by the European Community's Seventh Framework Programme (FP7/2007-2013) under grant agreement no. 282521 - the SAFEGUARD project.
