Exenatide Compared With Insulin Glargine to Change Liver Fat Content in Type 2 Diabetes
Exenatide Compared With Insulin Glargine to Change Liver Fat Content in Type 2 Diabetes
The purpose of this study is to evaluate whether exenatide is superior to insulin glargine
 (after 24 weeks) in reducing liver fat content (by MRS) in patients with newly diagnosed type
 2 diabetes mellitus and concomitant non-alcoholic fatty-liver disease(NAFLD).
This is a randomized, open-label, parallel-group, active controlled, multi-center clinical
 trial to investigate whether exenatide is superior to insulin glargine in reducing liver fat
 content in patients with newly diagnosed type 2 diabetes mellitus and concomitant
 NAFLD.Patients with type 2 diabetes and concomitant NAFLD from 18-70 years of age, with
 inadequate glycaemic control defined as 7% ≤ HbA1c ≤ 10% and BMI≥24kg/ m2 at the time of
 screening. Patients should be on diet and exercise but drug treatment naive, no use of any
 glucagon-like peptide-1(GLP-1) analogues or insulin within 3 months before enrolment.Patients
 will have an screening period 2 weeks, and a 24-week open label treatment period.

 All demographic data variables collected by descriptive analysis tests are used. Qualitative
 variables use absolute frequency and percentage, and numeric variables use average, mean,
 median, standard deviation, maximum, minimum, quartiles, etc. Unless specifically stated,
 statistical significance will be defined as P<0.05 in the whole analysis procedure.For the
 primary endpoint of this study, superiority test will be applied to the quantitative data of
 these two groups. For secondary and exploratory efficacy variables, difference test will be
 used to analyse repeated measurement data from two groups. For essential Safety parameters,
 difference test will be used to analyse the differences between two groups.The analysis of
 all primary and secondary endpoints of efficacy and safety must be based on the Full Analysis
 Set (FAS). As supporting evidence, the analysis of primary endpoint variables must also
 comply with the Pre-protocol (PPS) Analysis.
