LIRAINS: Study of Liraglutide Versus Insulin on Liver Fat Fraction in Patients With Type 2 Diabetes
Study Details
Study Description
Brief Summary
This study is conducted to test the hypothesis that in type 2 diabetic adults with fatty liver who are resistant to metformin, treatment with liraglutide in combination with metformin will cause an absolute reduction in liver fat superior to insulin-metformin treatment within a 3-month period, as measured by magnetic resonance imaging (MRI).

Detailed Description
Background: Non-alcoholic fatty liver disease (NAFLD) can now be identified in 70% of patients with type 2 diabetes. Insulin can be introduced at any point in the treatment of diabetes, but is potentially lipogenic. Preliminary studies have shown conflicting results on the impact of insulin on fatty liver.
Objectives: This study is conducted to test the hypothesis that in type 2 diabetic adults with NAFLD who are resistant to metformin, treatment with liraglutide in combination with metformin will cause an absolute reduction in liver fat superior to insulin-metformin treatment within a 3-month period, as measured by in vivo MRI and MRS.
Design: This will be a prospective, open label, randomized parallel trial to evaluate whether 12 weeks of treatment with a) liraglutide-metformin will improve steatosis in type 2 diabetic adults with NAFLD compared to treatment with b) insulin-metformin. Before and post-treatment MRI and MRS will be read blindly for quantification of steatosis. The primary outcome measure is defined as an improvement in steatosis of 5% before and after treatment between the 2 treatment groups.
Methods: Thirty-six patients will be randomized to either study group. After baseline metabolic measurements by blood sampling, transient ultrasound elastography, MRI and MRS, all subjects will be given metformin with a starting dose of 500 mg in one tablet twice daily. In addition, patients will be randomized to receive either liraglutide (0.6 - 1.8 mg subcutaneous per day ) or insulin glargine with an initial bedtime starting dose of 10 IU for a duration of 3 months.
Expected results: The results of this study will provide preliminary data for a large scale study comparing the 2 therapeutic regimen and establish the utility of MRI and MRS to monitor medical treatment in diabetic patients with fatty liver disease.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Liraglutide-Metformin Liraglutide (Victoza, Novo Nordisk) at a dose of 0.6 - 1.8 mg subcutaneous per day until the end of the study. All subjects will be given metformin with a starting dose of 500 mg in one tablet twice daily given before or during meals for the duration of the study. |
Drug: Liraglutide-metformin vs insulin-metformin
Liraglutide (Victoza, Novo Nordisk) at a dose of 0.6 - 1.8 mg subcutaneous per day.
Insulin glargine (Lantus, Sanofi-Aventis) with an initial bedtime starting dose of 10 IU.

Experimental: Insulin-Metformin Insulin glargine (Lantus, Sanofi-Aventis) with an initial bedtime starting dose of 10 IU. The patients will be taught to increase their insulin dose by 1 unit each day until achieving an FPG ≤ 7.0 mmol/L. All subjects will be given metformin with a starting dose of 500 mg in one tablet twice daily given before or during meals for the duration of the study. |
Drug: Liraglutide-metformin vs insulin-metformin
Liraglutide (Victoza, Novo Nordisk) at a dose of 0.6 - 1.8 mg subcutaneous per day.
Insulin glargine (Lantus, Sanofi-Aventis) with an initial bedtime starting dose of 10 IU.
