Brief Summary:
Nonalcoholic fatty liver disease (NAFLD) represents a spectrum of diseases ranging from simple steatosis to nonalcoholic steatohepatitis (NASH), the progressive form of liver disease that can lead to cirrhosis and liver-related mortality in persons who drink little or no alcohol. NAFLD is defined as the presence of hepatic steatosis with no evidence of hepatocellular injury in the form of ballooning of the hepatocytes. NASH is defined as the presence of hepatic steatosis and inflammation with hepatocyte injury (ballooning) with or without fibrosis. NASH is benign in many affected individuals but can cause progressive liver injury and, indeed, may be the major cause of cryptogenic cirrhosis1. Currently, there is no FDA approved treatment for NAFLD. Weight loss and exercise are the recommended but often difficult maintain these lifestyle changes in the long term and therefore therapeutic agents have been investigated. In this study, we propose to treat 50 patients with NAFLD and diabetes with either sitagliptin or placebo for 24 weeks. After an initial evaluation for insulin sensitivity and MRI liver fat distribution, patients will receive either 100 mg/day of sitagliptin or placebo. Patients will be monitored at regular intervals for symptoms of liver disease, side effects of sitagliptin and serum biochemical and metabolic indices. At the end of 24-weeks, patients will have a repeat medical evaluation, liver MRI and an optional liver biopsy. Pre and post treatment MRI-derived liver fat content and insulin sensitivity will be compared. The primary end point of successful therapy will be improvement in hepatic steatosis measured by MRI. Secondary end points will be improvement in insulin sensitivity and liver biochemistry.

Condition or disease Intervention/treatment Phase

Detailed Description:

Primary objectives:

1. To examine the efficacy of sitagliptin 100 mg orally daily versus placebo in improving hepatic steatosis assessed by magnetic resonance imaging in patients with NAFLD.

Secondary objectives:

  1. To examine the efficacy of sitagliptin in improving serum AST in patients with NAFLD.
  2. To examine the efficacy of sitagliptin in improving serum ALT in patients with NAFLD.
  3. To examine the efficacy of sitagliptin in improving serum LDL in patients with NAFLD.
  4. To examine the efficacy of sitagliptin in the improvement of insulin sensitivity in patients with NAFLD.

Ages Eligible for Study:   18 Years to 99 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

44 patients with NAFLD will be randomized to either sitagliptin or placebo for 24-weeks. Enrollment of 50 patients is needed to allow for exclusion of some patients after initial evaluation and a dropout of a small number of patients because of intolerance to sitagliptin.

Inclusion criteria:

  1. Age at entry at least 18 years.
  2. Serum alanine (ALT) or aspartate (AST) aminotransferase activities that are above the upper limits of normal. 19 or more in women and 30 or more in men.
  3. Evidence of hepatic steatosis or liver fat (≥5%) by MRI.
  4. Prediabetic patients and controlled diabetic patients as defined by the ADA position statement on diabetes mellitus. Prediabetics have a HbA1c of 5.7 to 6.4 and controlled diabetic patients have an HbA1c between 6.4 and 8.0.
  5. Written informed consent.

Exclusion criteria:

  1. Uncontrolled diabetes defined as a Hb A1c ≥ 8.0.
  2. Evidence of another form of liver disease.

    • Hepatitis B as defined as presence of hepatitis B surface antigen (HBsAg).
    • Hepatitis C as defined by presence of hepatitis C virus (HCV) RNA in serum.
    • Autoimmune hepatitis as defined by anti-nuclear antibody (ANA) of 1:160 or greater and liver histology consistent with autoimmune hepatitis or previous response to immunosuppressive therapy.
    • Autoimmune cholestatic liver disorders as defined by elevation of alkaline phosphatase and anti-mitochondrial antibody of greater than 1:80 or liver histology consistent with primary biliary cirrhosis or elevation of alkaline phosphatase and liver histology consistent with sclerosing cholangitis.
    • Wilson disease as defined by ceruloplasmin below the limits of normal and liver histology consistent with Wilson disease.
    • Alpha-1-antitrypsin deficiency as defined by alpha-1-antitrypsin level less than normal and liver histology consistent with alpha-1-antitrypsin deficiency.
