7. Female patients and male patients with female partners of child bearing potential must use adequate contraception or have a sterilized partner for the duration of the study. Adequate contraception is defined as: systemic hormonal contraceptives; intrauterine device or barrier method of contraception in conjunction with spermicide; or agree to sexual abstinence, defined as a patient refraining from heterosexual intercourse during the entire period of risk associated with the study treatments and in line with their preferred and usual lifestyle. Hormonal contraceptives must be on a stable dose for at least one month before baseline.

Placebo	Placebo capsules	2 x placebo 500 mg capsules orally administered twice a day (4 capsules daily) for 16 weeks

Primary Outcome Measures

Name	Time	Method
Change in Serum ALT (Alanine Aminotransferase) From Baseline to Week 16	16 Weeks	Change in serum ALT from baseline to Week 16 using ANCOVA.
Change in Liver Stiffness Measurements by Transient Elastography From Baseline to Week 16	16 Weeks	To evaluate change in liver stiffness measurements using Transient Elastography from baseline to Week 16 using FibroScan® 502 Touch model or equivalent.
Number of Treatment Emergent Adverse Events (TEAEs) in Each Treatment Group Leading to Treatment Discontinuation	20 Weeks	Subjects with at least 1 TEAE leading to treatment discontinuation

Secondary Outcome Measures

Name	Time	Method
Change in Serum ALT (Alanine Aminotransferase) From Baseline to Weeks 2, 4, 8 and 12	12 Weeks	Change in serum ALT from baseline to weeks 2, 4, 8 and 12.
Change in AST (Aspartate Aminotransferase) From Baseline to Weeks 2, 4, 8, 12 and 16	16 Weeks	Change in serum AST from baseline to weeks 2, 4, 8, 12 and 16.
Change in AST:ALT Ratio From Baseline to Weeks 2, 4, 8, 12 and 16	16 Weeks	Change in AST: ALT ratio from baseline to weeks 2, 4, 8, 12 and 16.
Change in FIB-4 Index From Baseline to Week 16	16 Weeks	Change in FIB-4 Index from baseline to week 16. This index is based on age, platelet count, ALT level, and AST level and will be assessed at Baseline (Visit 2) and week 16 (Visit 10). FIB-4 was calculated using the following formula: FIB4 = (Age (years) x AST (U/L))/(Platelet count (10\^9/L) x √ALT (U/L)). A decrease in FIB-4 represents a positive outcome. A FIB-4 Index of \<1.45 indicates none to moderate fibrosis and an Index of \>3.25 indicates advanced fibrosis.
Change in Non-Alcoholic Fatty Liver Disease (NAFLD) Fibrosis Score (NFS) From Baseline to Week 16	16 Weeks	Change in NAFLD fibrosis score (NFS) from baseline to week 16. The NFS is based on age, hyperglycemia, BMI, platelet count, albumin level, and AST/ALT ratio. NFS was calculated using the following formula: NAFLD fibrosis score = -1.675 + 0.037 × age (years) + 0.094 × BMI (kg/m\^2) + 1.13 × IFG/diabetes (yes = 1, no = 0) + 0.99 × AST/ALT ratio - 0.013 × platelet (×10\^9/l) - 0.66 × albumin (g/dl). A decrease in NFS score represents a positive outcome. An NFS score of \<-1.455 indicates no advanced fibrosis and a score of \>0.676 indicates liver fibrosis.
Change in ELF (Enhanced Liver Fibrosis Score) From Baseline to Week 16	16 Weeks	Change in ELF from baseline to week 16. Enhanced Liver Fibrosis score is an extracellular matrix marker set consisting of tissue inhibitor of metalloproteinases 1 (TIMP-1), amino-terminal propeptide of type III procollagen (PIIINP) and hyaluronic acid (HA). A decrease in ELF score represents a positive outcome. The ELF score was calculated for the instrument based on the following equation: ELF score = 2.494 + 0.846 In (CHA) + 0.735 In (CPIIINP) + 0.391 In (CTIMP-1). An ELF score of less than 7.7 indicates no fibrosis. An ELF score greater than or equal to 9.8 indicates severe fibrosis. An ELF score of 11.3 or greater indicates cirrhosis.
Change in HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) From Baseline to Weeks 2, 4, 8, 12 and 16	16 Weeks	Change in HOMA-IR from baseline to weeks 2,4,8,12,16. Homeostatic model assessment for insulin resistance (HOMA-IR) was assessed as a measure of insulin resistance. HOMA-IR is calculated by multiplying fasting plasma insulin by fasting plasma glucose, then dividing by the constant 405. A decrease in HOMA-IR indicates a positive outcome. HOMA-IR values of greater than 1.9 indicates early insulin resistance and levels above 2.9 indicate significant insulin resistance.
Change in Adipo-IR (Adipose Tissue Insulin Resistance) From Baseline to Weeks 2, 4, 8, 12 and 16.	16 Weeks	Change in Adipo-IR from baseline to weeks 2, 4, 8, 12 and 16. Adipose tissue insulin resistance (Adipo-IR) was assessed as a measure of insulin resistance. Adipo- IR is calculated by multiplying fasting non-esterified fatty acids by fasting insulin. A decrease in Adipo-IR indicates a positive outcome.
Change in Hepatic Fat Measured by CAP (Controlled Attenuation Parameter) From Baseline to Week 16.	16 Weeks	Change in hepatic fat measured by CAP (controlled attenuation parameter) from baseline to week 16 using FibroScan® 502 Touch model or equivalent. CAP score is measured in decibels per meter (dB/m). A reduction in hepatic fat measured non-invasively by CAP indicates an improvement in hepatic steatosis. CAP scores range from 100 to 400dB/m. 0 to 237 dB/M indicates no hepatic steatosis, 238 to 260 dB/m indicates mild hepatic steatosis, 260 to 290 dB/m indicates moderate steatosis and a CAP score greater than 290 dB/m indicates severe steatosis.
