Clinical Trial Summary

Non-alcoholic fatty liver disease (NAFLD) is commonly associated with obesity, metabolic syndrome and type 2 diabetes. NAFLD, in patients with type 2 diabetes, has been shown to be associated with lipid abnormalities (such as hypertriglyceridemia and decreased HDL-cholesterol) and increased cardiovascular risk. Such lipid abnormalities (hypertriglyceridemia and decreased HDL-cholesterol) are very frequent in patients with type 2 diabetes. Moreover, NAFLD is a risk for further development of cirrhosis (estimated between 3 and 5%).

Animal studies have shown that liraglutide is able to decrease liver fat content, but the effect of liraglutide on liver fat content in patients with diabetes remains unknown.

In addition, human studies with liraglutide have shown significant modification of plasma lipids, such as reduction of plasma triglycerides and LDL-cholesterol. However, the mechanisms responsible for these liraglutide induced lipid modifications are not yet known.

Because increased in liver fat content and hypertriglyceridemia are associated in patients with type 2 diabetes, it seems interesting to study the effect of liraglutide on both liver fat content and lipid metabolism using gold-standard methods (proton-spectroscopy for liver fat content assessment and kinetic study with stable isotope to study lipoprotein metabolism).

This is a monocentric study. Fatty liver content will be performed by proton-spectroscopy in patients with type 2 diabetes (n=120) before and after a 6 month period of liraglutide therapy (1.2 mg/day).

Moreover, an in vivo kinetic study will be performed with stable isotopes (13C leucine) in 10 patients among the 120 patients with type 2 diabetes (n=10) before and after a 6-month period of liraglutide (1.2 mg/day) therapy. Each kinetic study will be performed during a 2-day hospitalization

For the main study, 3 visits will be performed:

• a first visit at T0, before starting the treatment with liraglutide, including clinical and biological measurements and liver fat content assessment by proton-spectroscopy

• a visit at 3 months including clinical and biological measurements

• and a visit at 6 months including clinical and biological measurements and liver fat content assessment by proton-spectroscopy

For the kinetic substudy, performed in 10 patients, a kinetic study with stable isotope will been performs during a 48h-hospitalization before starting the treatment with liraglutide and after 6 month-treatment with liraglutide
