Study Endpoints
Primary Endpoints
Percent Change From Baseline in Whole Liver Proton Density Fat Fraction (PDFF) at Day 42
Baseline, Day 42

Magnetic resonance imaging proton density fat fraction (MRI-PDFF) technique is an established method that enables quantification of fat content in the liver. It measures the fraction of mobile protons in the liver attributable to fat content and provides whole liver coverage so that fat content can be assessed across 8 Couinaud liver segments. Whole liver PDFF = PDFFs for (Segment I + Segment II + Segment III + Segment IVa + Segment IVb + Segment V + Segment VI + Segment VII + Segment VIII) divided by total number of segments assessed.

Secondary Endpoints
Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
Baseline up to 35 days from last dose of study drug or early termination: (maximum up to Day 77)
Number of Participants With Laboratory Abnormalities
Baseline up to 35 days last from dose of study drug or early termination (maximum up to Day 77)
Maximum Change (Increase or Decrease) From Baseline to Post-last Dose of Study Drug in Vital Signs: Blood Pressure
Baseline, Post-last dose of study drug (up to Day 42)
