Main Inclusion Criteria: 1. Male and female subjects between the ages of 18 and 70 years, inclusive, at Screening. 2. Suspected or confirmed diagnosis of noncirrhotic NAFLD/NASH without advanced hepatic fibrosis by one of the following: 1. Histologically with liver biopsy within 2 years prior to Screening (documentation with pathology report); or 2. Radiologically with ≥5% steatosis measured by magnetic resonance imaging-derived proton density fat fraction (MRI-PDFF), or controlled attenuation parameter (CAP) \>238 dB/m via FibroScan assessment, or presence of hepatic steatosis on abdominal ultrasound ; or 3. Clinically with a diagnosis of Metabolic Syndrome (MetS) reflecting the presence of at least 3 of 5 factors/criteria (ie, abdominal obesity, elevated triglycerides, reduced HDL-C, elevated blood pressure, and/or elevated fasting glucose \[IFG or type 2 diabetes mellitus\]) as defined by the National Cholesterol Education Program's Adult Treatment Panel III (NCEP ATP III) \[Grundy 2005\]; and fatty liver on imaging within 1 year prior to Screening. Key Exclusion Criteria: 1. History or presence of cirrhosis as assessed by Investigator following review of diagnostic measures (clinical, imaging, histopathology, or laboratory). 2. Clinical evidence of hepatic decompensation (laboratory or clinical abnormalities- ascites, variceal bleeding, etc.). 3. History or presence of other concomitant liver disease (eg, hepatitis B \& C, alcoholic liver disease, autoimmune liver disease, primary biliary cirrhosis, primary sclerosing cholangitis, hemochromatosis, Wilson's disease, alpha-1 antitrypsin (A1AT) deficiency, bile duct obstruction, liver primary or metastatic cancer, drug-induced liver disease.
