Study Overview
Brief Summary
Does the novel drug decrease liver fat in subjects with NASH or NAFLD as compared to placebo
Detailed Description
We propose to evaluate hepatic fat and hepatic fibrosis using magnetic resonance elastography (MRE) liver (pre vs. post). We will also establish glucose tolerance status by our established labeled oral glucose tolerance test (OGTT) (6,6 ²H2 glucose). Following baseline evaluation subjects with biopsy/MRE proven NASH will be randomized to one of two groups and treated either with active drug (AZ compound) or placebo for 12 weeks (plus or minus 1 week). Subjects with history suggestive of non-alcoholic fatty liver disease (NAFLD) or NASH will be invited to participate. If they meet criteria following initial screening they will be included in the study. OGTT, liver MRE will be repeated. Liver enzymes [aspartate aminotransferase (AST), alanine aminotransferase (ALT),alkaline phosphatase (ALP)] as well as other safety tests [creatine phosphokinase (CPK), thyroid stimulating hormone (TSH), international normalized ratio (INR),total bilirubin] will be measured before, monthly during therapy and at one month following therapy. Furthermore, we will also do the subgroup analysis in NASH/NAFLD subjects with and without diabetes to see the effect of the drug.

Arms & Interventions
Active drug AZ compound
AZ compound 800 mg/day for 12 weeks (plus or minus 1 week) in two divided doses morning (400 mg) and evening (400 mg).
Intervention: AZ compound (Drug)
Placebo
Placebo 800 mg/day for 12 weeks (plus or minus 1 week) in two divided doses morning (400 mg) and evening (400 mg).
Intervention: Placebo (Other)
Outcomes
Primary Outcomes
Percentage Change in Hepatic Fat
Time Frame: baseline, approximately 12 weeks
Percentage Hepatic fat measured using Magnetic Resonance Imaging (Proton Density Fat Fraction). A cut-off of \<5% is used to distinguish between normal and fatty liver.
Number of Participants With no Conversion of [13C] Cortisone to [13C] Cortisol
Time Frame: baseline, approximately 12 weeks
Hepatic conversion of \[13C\] cortisone to \[13C\] cortisol was assessed before and after the treatment in both groups using the triple tracer cortisol test.
Secondary Outcomes
- Liver Fibrosis Measured With MRE in kPa(baseline, approximately 12 weeks)
- Total Insulin Sensitivity (Si) and Hepatic Insulin Sensitivity (Si Liver)(baseline, approximately 12 weeks)
