• Evidence of current, chronic liver diseases at the time of baseline:

a. Primary biliary cholangitis b. Primary sclerosing cholangitis c. Chronic hepatitis B or D d. Hepatitis C, as defined by the presence of hepatitis C virus antibody (anti-HCV) with detected circulating ribonucleic acid (RNA) within two years prior to Screening, or during Screening Period.

e. HCV eradication by antiviral treatment less than three years prior to Screening.

f. History or evidence of current active autoimmune hepatitis g. History or evidence of Wilson's disease h. History or evidence of alpha-1-antitrypsin deficiency i. Evidence of genetic hemochromatosis (hereditary, primary) j. Evidence of drug-induced liver disease k. Known bile duct obstruction. l.

• Evidence of hepatic impairment or decompensation within 3 months prior to baseline, as defined by any of the following parameters:

a. History of ascites, or hepatic encephalopathy b. History of variceal bleeding c. Serum albumin < 3.5 g/dL, except as explained by non-hepatic causes. d. International Normalized Ratio (INR) ≥ 1.3, except for participants under anticoagulant treatment.

o NOTE: INR may be repeated once to reassess eligibility e. Total bilirubin (TBL) ≥ 1.5 ULN

o NOTE: Patients with Gilbert's Syndrome are eligible with a total bilirubin above 1.5 × ULN if reticulocyte count is within normal limits (typically 0.5% to 2.5%), hemoglobin is within normal limits (typically 13.5 to 17.5 g/dL for men or 12.0 to 15.5 g/dL for women), and direct bilirubin is <20% of total bilirubin f. Platelet count < 110,000/mm3

• Prior history of medium or large varices
• Bariatric surgery of any kind within 2 years prior to the baseline visit Medical History and Concurrent Disease Exclusions Cardiovascular diseases
• Any of the following diseases or procedures within 24 weeks prior to baseline:

• Myocardial infarction (MI)
• Cardiac revascularization surgery (coronary artery bypass graft / percutaneous transluminal coronary angioplasty (CABG / PTCA))
• Unstable angina
• Transient ischemic attack, stroke or cerebrovascular disease Hematological and oncological diseases
• Active malignancy with a complete remission date within 2 years prior to the baseline visit (except for treated basal cell carcinoma or treated squamous cell carcinoma of the skin or resected carcinoma of the cervix) Other exclusion conditions
• Immunocompromised participants such as participants that underwent organ transplantation or are diagnosed with human immunodeficiency virus (HIV) or participants with ongoing chemotherapy for stable malignant disease (such as a PD-1 inhibitor)
• Any other known serious disease (such as major infection, clinically significant gastrointestinal disorder, major autoimmune disease) or other disease which in the Investigator's opinion would exclude the participant from the study.
• Mental handicap, limited capacity of recognition, inability to follow the study procedures as evaluated by the Investigator, or any history of clinically important emotional and/or psychiatric illness.
• Use of non-permitted concomitant medication within 8 weeks prior to the initial baseline visit (A transient intake < 4 weeks may be allowed after approval of the Medical Monitor)

• Vitamin E >400 units per day. Participants on stable vitamin E therapy (same doses) for the last 12 weeks prior to baseline are eligible but the therapy should be maintained at stable dose throughout the study
• Pioglitazone >15 mg per day. Participants on stable pioglitazone therapy (same doses) for the last 12 weeks prior to baseline are eligible but the therapy should be maintained at stable dose throughout the study
• GLP1-RA, SGLT2-I unless on stable doses for the last 12 weeks prior to baseline
• Amiodarone within 12 months of enrollment
• Methotrexate within 12 months of enrollment
• Chronic use (> 2 consecutive weeks) of corticosteroids with a systemic effect at doses ≥ 5 mg/day of oral prednisone (or equivalent)
• Tamoxifen within 12 months of enrollment
• Estrogens at doses greater than those used for hormone replacement or contraception
• Anabolic steroids except testosterone replacement
• Valproic acid
• Any other medications known to affect liver function/steatosis at the Investigator's discretion (including vitamins, herbal and dietary supplements)
• Contraindications to MRI, including:

• Participants with incompatible pacemakers, metallic cardiac valves, magnetic material such as surgical clips, implanted electronic infusion pumps or other conditions that would preclude proximity to a strong magnetic field
• History of extreme claustrophobia
• The participant cannot fit inside the magnetic resonance scanner cavity
