About this trial

In this study the investigators will quantitate hepatic mitochondrial fluxes in T2D patients with NAFL and NASH before and after 16-weeks treatment with the insulin sensitizer pioglitazone

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Confirmed T2D based on OGTT (2 h glucose ≥200 mg/dl).

Treated with diet, metformin, and/or sulfonylurea and in good general health determined by medical history, physical exam, and routine blood chemistries;

age = 18-80 years;

BMI = 25-40 kg/m2;

Disqualifiers

Alcohol consumption >14 units/week for women and >21 units/week for men.

Liver cirrhosis (fibrosis stage 4).

Evidence of other forms of chronic liver disease, including alcoholic liver disease, hepatitis B and C, primary biliary cholangitis, suspected/proven liver cancer and any other liver disease other than NAFLD.

Type 1 diabetes and/or GAD positive subjects.

Trial design

Design model

  • Placebo

    Other intervention

    Placebo for pioglitazone
