Brief Summary:
This study will compare the effects of AXA1125, an orally active mixture of amino acids, compared to placebo, on improving fat and inflammation (steatohepatitis) as well as fibrosis in subjects with non alcoholic steatohepatitis (NASH). as well as the safety and tolerability of AXA1125. Subjects will take one of two different doses of AXA1125 or a placebo twice daily, and a liver biopsy will be done at the beginning and end of the 48-week study.

Primary Outcome Measures :
  1. Improvement in steatohepatitis [ Time Frame: Baseline to Week 48 ]
    2-point improvement from baseline to Week 48 in the non-alcoholic fatty liver disease (NAFLD) Activity Score (NAS) based on a scale from 0-8 with 0 being no NASH and 8 being the highest score

Secondary Outcome Measures :
  1. Resolution of NASH without worsening of fibrosis [ Time Frame: Baseline to week 48 ]
    The proportion of subjects with resolution of NASH with no worsening of fibrosis defined as a post-treatment ballooning score of 0 and an inflammation score of 0 or 1 on liver biopsy.

  2. Improvement of fibrosis by one stage without worsening of NASH [ Time Frame: Baseline to week 48 ]
    The proportion of subjects who have at least a 1-stage improvement in fibrosis and no worsening of NASH based on liver biopsy 0 being no fibrosis and 4 being the worse.

  3. Incidence of study drug emergent adverse events (AEs) and serious adverse events (SAEs) [ Time Frame: Baseline to week 48 ]
  4. Change from baseline in liver stiffness as measured by vibration controlled transient elastography (Fibroscan™) [ Time Frame: Baseline to week 48 ]
  5. Change from baseline in hepatic fat as measured by MRI [ Time Frame: Baseline to week 48 ]
  6. Change from baseline in measures of glucose control as determined by glycated hemoglobin (HbA1c) [ Time Frame: Baseline to week 48 ]
