• History of stomach or intestinal surgery or resection within the six months prior to screening that would potentially alter absorption and/or excretion of orally administered drugs as judged by the investigator.
• Unstable cardiovascular disease, including:
  • unstable angina, (i.e., new or worsening symptoms of coronary heart disease) in the 90 days before screening and throughout the screening period; acute coronary syndrome in the 24 weeks before screening and throughout the screening period;

  • stroke or transient ischemic attack in the 24 weeks before screening
• Receiving an elemental diet or parenteral nutrition.

Other illness

• History of liver transplant
• Type 1 diabetes mellitus
• History of benign or malignant bladder tumors, and/or hematuria or has current hematuria except due to a urinary tract infection.
• History of malignancy in the past 5 years and/or active neoplasm with the exception of resolved superficial nonmelanoma skin cancer.
• Known allergy, sensitivity or intolerance to the study drug, comparator or formulation ingredients.
• History or other evidence of severe illness or any other conditions that would make the subject, in the opinion of the investigator, unsuitable for the study (such as poorly controlled psychiatric disease, HIV, coronary artery disease or active gastrointestinal conditions that might interfere with drug absorption)
• Chronic pancreatitis or pancreatic insufficiency.

Lab values

• Evidence of portal hypertension (low platelet count, esophageal varices, ascites, history of hepatic encephalopathy, splenomegaly) at screening.
• Treatment with glucagon-like peptide-1 receptor agonists (GLP-1RAs), sodium glucose cotransporter- 2 (SGLT-2) inhibitors, and dipeptidyl peptidase 4 inhibitors (gliptins) unless stable for 120 days prior to screening or, if a historical biopsy is used, from 120 days prior to baseline liver biopsy until randomization.
• History of myopathies or evidence of active muscle disease demonstrated by CPK ≥ 5 times ULN at screening.
• For subjects with elevated baseline ALT, AST, or ALP; ALT, AST, or ALP exceeding by more than 50% at Visit 2 reading compared to Visit 1 Note: If the ALT, AST or ALP values at Visit 2 exceed by more than 50% from Visit 1, then a third value will be measured to assess for the trend. If the third value shows continued increase ≥ 10%, then subject is considered ineligible for randomization.
• Any of the following laboratory values at screening:
  • Hemoglobin \<9 g/dL
  • WBC count \<2.5 × 103/µL
  • Neutrophil count \<1.5 × 103/µL
  • Platelets \<140 × 103/µL \[if low platelet count is due to reasons other than liver disease as assessed by a hematologist, participants may be eligible if the platelet count is \> 75 x 103/µL\] as per investigator's discretion\]
  • INR ≥ 1.3 (in the absence of anticoagulants)
  • Total bilirubin \> ULN except in Gilbert's syndrome. In subjects with known Gilbert's syndrome, direct bilirubin \> 2 x ULN
