简要总结
Does the novel drug decrease liver fat in subjects with NASH or NAFLD as compared to placebo
详细描述
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.

结局指标
主要结局
Percentage Change in Hepatic Fat
时间窗: 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
时间窗: 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.
次要结局
- 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)
