Primary Outcome Measures
NameTimeMethod
Relative Change in the Percentage of Liver Fat Mass (Assessed by MRI-PDFF) From Baseline to Week 12/End of Treatment (Unstratified Wilcoxon Sensitivity Analysis)Baseline to Week 12

MRI acquisitions were performed at pre-qualified local MRI facilities using qualified and standardized instruments at high field strength (3 T or 1.5T) without oral or intravenous contrast. All acquisitions images were transferred to a central reader vendor for central calculation and measurement of MRI-PDFF using the method of Zhong et al. to estimate water and fat components. A 3 cm2 ROI was placed in each Couinaud segment. Central reading was masked to treatment group, clinical data, study site of origin and timepoint.

Relative Change in the Percentage of Liver Fat Mass (Assessed by Magnetic Resonance Imaging - Proton Density Fat Fraction [MRI-PDFF]) From Baseline to Week 12/End of Treatment (EOT)Baseline to Week 12

MRI acquisitions were performed at pre-qualified local MRI facilities using qualified and standardized instruments at high field strength (3 T or 1.5T) without oral or intravenous contrast. All acquisitions images were transferred to a central reader vendor for central calculation and measurement of MRI-PDFF using the method of Zhong et al. to estimate water and fat components. A 3 cm2 region of interest (ROI) was placed in each Couinaud segment. Central reading was masked to treatment group, clinical data, study site of origin and timepoint.

Relative Change in the Percentage of Liver Fat Mass (Assessed by MRI-PDFF) From Baseline to Week 12/End of Treatment (Per Protocol Sensitivity Analysis)Baseline to Week 12

MRI acquisitions were performed at pre-qualified local MRI facilities using qualified and standardized instruments at high field strength (3 T or 1.5T) without oral or intravenous contrast. All acquisitions images were transferred to a central reader vendor for central calculation and measurement of MRI-PDFF using the method of Zhong et al. to estimate water and fat components. A 3 cm2 ROI was placed in each Couinaud segment. Central reading was masked to treatment group, clinical data, study site of origin and timepoint.

Relative Change in the Percentage of Liver Fat Mass (Assessed by MRI-PDFF) From Baseline to Week 12/End of Treatment (Subgroup Analysis - Type 2 Diabetes Mellitus [T2DM])Baseline to Week 12

MRI acquisitions were performed at pre-qualified local MRI facilities using qualified and standardized instruments at high field strength (3 T or 1.5T) without oral or intravenous contrast. All acquisitions images were transferred to a central reader vendor for central calculation and measurement of MRI-PDFF using the method of Zhong et al. to estimate water and fat components. A 3 cm2 ROI was placed in each Couinaud segment. Central reading was masked to treatment group, clinical data, study site of origin and timepoint.

Secondary Outcome Measures
NameTimeMethod
Change in High Density Lipoprotein-Cholesterol (HDL-C) From Baseline to Week12/End of TreatmentBaseline to Week 12

Blood samples were collected, handled and stored according to the instructions described in the laboratory manual and all measurements were performed at a central laboratory.

Change in Low Density Lipoprotein-Cholesterol (LDL-C) From Baseline to Week12/End of TreatmentBaseline to Week 12

Blood samples were collected, handled and stored according to the instructions described in the laboratory manual and all measurements were performed at a central laboratory.

Change in Triglycerides From Baseline to Week12/End of TreatmentBaseline to Week 12

Blood samples were collected, handled and stored according to the instructions described in the laboratory manual and all measurements were performed at a central laboratory.

Percentage of Responders (Relative Reduction of at Least 30% in Liver Fat Mass) at Week 12/End of TreatmentBaseline to Week 12

Responders were defined as patients who achieved a clinically meaningful relative reduction of at least 30% in liver fat mass From baseline to Week 12/EOT as assessed by MRI-PDFF

Change in Alanine Amino Transferase (ALT) From Baseline to Week 12/End of TreatmentBaseline to Week 12

Blood samples were collected, handled and stored according to the instructions described in the laboratory manual and all measurements were performed at a central laboratory.

Change in Body Weight From Baseline to Week 12/End of TreatmentBaseline to Week 12

Body weight was measured using a scale with appropriate resolution, placed on a stable, flat surface. Shoes, bulky layers of clothing, and jackets had to be removed so that only light clothing remained.

Change in Aspartate Amino Transferase (AST) From Baseline to Week 12/End of TreatmentBaseline to Week 12

Blood samples were collected, handled and stored according to the instructions described in the laboratory manual and all measurements were performed at a central laboratory.

Absolute Change in the Percentage of Liver Fat Mass (Assessed by MRI-PDFF) From Baseline to Week 12/End of TreatmentBaseline to Week 12

MRI acquisitions were performed at pre-qualified local MRI facilities using qualified and standardized instruments at high field strength (3 T or 1.5T) without oral or intravenous contrast. All acquisitions images were transferred to a central reader vendor for central calculation and measurement of MRI-PDFF using the method of Zhong et al. to estimate water and fat components. A 3 cm2 ROI was placed in each Couinaud segment. Central reading was masked to treatment group, clinical data, study site of origin and timepoint.

Change in Fibrosis-4 (Fib-4) Score From Baseline to Week 12/End of TreatmentBaseline to Week 12

Fib-4 score is a non invasive method based on clinical determinations that indicates the level of fibrosis/ scarring of the liver. The set cutoffs for this scoring are: Fib-4 \< 1.45: absence of cirrhosis; Fib-4 between 1.45 - 3.25: inconclusive and Fib-4 \> 3.25: cirrhosis.

Fib-4 score was calculated as (Age \[years\] × AST \[U/L\]) / (platelet \[10\^9/L\] × √\[ALT \[U/L\]\]). Blood samples used for AST, ALT and platelet counts were collected, handled and stored according to the instructions described in the laboratory manual and all measurements were performed at a central laboratory.

Change in Fasting Plasma Glucose (FPG) From Baseline to Week12/End of TreatmentBaseline to Week 12

Blood samples were collected, handled and stored according to the instructions described in the laboratory manual and all measurements were performed at a central laboratory.

Change in Glycated Hemoglobin (HbA1c) From Baseline to Week12/End of TreatmentBaseline to Week 12

Blood samples were collected, handled and stored according to the instructions described in the laboratory manual and all measurements were performed at a central laboratory.

Change in Total Cholesterol From Baseline to Week12/End of TreatmentBaseline to Week 12

Blood samples were collected, handled and stored according to the instructions described in the laboratory manual and all measurements were performed at a central laboratory.
