ALP ≥ 1.67 x ULN at both Visits 1 and 2 and \< 30% variance between the levels from Visit 1 to Visit 2 5. Total bilirubin \< 2 x ULN at screening (Visit 1) 6. Must provide written informed consent and agree to comply with the trial protocol. Exclusion Criteria: 1. Consumption of 2 standard alcohol drinks per day if male and 1 standard alcohol drink per day if female for at least 3 consecutive months (12 consecutive weeks) within 5 year before screening (Note: 1 unit = 12 ounces of beer, 4 ounces of wine or 1 ounce of spirits/hard liquor). 2. History or presence of other concomitant liver diseases at screening: 1. Chronic hepatitis B or C virus (HBV, HCV) infection. (Note: However, If the subject has been treated for the HCV infection and has been cured for a duration of more than 2 years from screening, such subjects can be enrolled in the study) 2. Primary sclerosing cholangitis (PSC). 3. Alcoholic liver disease. 4. Autoimmune hepatitis (AIH) indicative of PBC with overlap syndrome. Note: The Paris criteria are commonly used to define the presence of PBC with features of AIH and have been endorsed by EASL and AASLD. According to these criteria, a diagnosis can be made in a patient with PBC as follows: At least two of the following: I. ALP \> 2 x ULN or GGT \> 5 x ULN. II. AMA positive III. Florid bile duct lesion on histology. AND At least two of the following three features: I. ALT \> 5 x ULN. II. Immunoglobulin G serum levels \> 2 x ULN or smooth muscle autoantibody positive. III. Moderate to severe interface hepatitis on histology. e. Hemochromatosis. f. Non-alcoholic steatohepatitis (NASH) on historical biopsy. 3.Cirrhosis with complications, including history or presence of: spontaneous bacterial peritonitis, hepatocellular carcinoma, ascites requiring treatment, encephalopathy, known large esophageal varices or history of variceal bleeding within one year prior to screening or history of hepatorenal syndrome. 5.Medical conditions that may cause non-hepatic increases in ALP (e.g., Paget's disease) or which may diminish life expectancy to \< 2 years, including known cancers. 6.Use of thiazolidinediones or fibrates (within 12 weeks prior to screening). 7.Use of obeticholic acid (OCA), azathioprine, cyclosporine, methotrexate, mycophenolate, pentoxifylline, budesonide and other systemic corticosteroids (Note: Prednisone dose should not be more than 10 mg per day); potentially hepatotoxic drugs (including α-methyl-dopa, sodium valproic acid, isoniazid, or nitrofurantoin) (within 12 weeks prior to screening). 9.History of bowel surgery (gastrointestinal \[bariatric\] surgery in the preceding 1 year or undergoing evaluation for gastrointestinal surgery (bariatric surgery for obesity, extensive small-bowel resection) or orthotopic liver transplant (OLT) or listed for OLT. 10.Type 1 diabetes mellitus. 11.Unstable cardiovascular disease, including: a. Unstable angina, (i.e., new or worsening symptoms of coronary heart disease in the 12 weeks before screening and throughout the Screening Period), acute coronary syndrome in the 24 weeks before screening and throughout the Screening Period, acute myocardial infarction in the 12 weeks before screening and throughout the Screening Period or heart failure of New York Heart Association class (III - IV) or worsening congestive heart failure, or coronary artery intervention, in the 24 weeks before screening and throughout the Screening Period. b. History/current unstable cardiac dysrhythmias. c. Uncontrolled hypertension at screening. d. Stroke or transient ischemic attack in the 24 weeks before screening. 12.History of intracranial hemorrhage, arteriovenous malformation, bleeding disorder, coagulation disorders, or screening blood tests that, in the opinion of the Investigator, indicate altered coagulability (e.g., PT, INR, aPTT) at screening. 13.An uncontrolled thyroid disorder 1. Uncontrolled hyperthyroidism: defined as any history of hyperthyroidism that has either not been treated with either radioactive iodine and/or surgery or that has been treated with radioactive iodine and/or surgery, but has required ongoing continuous or intermittent use of thyroid hormone synthesis inhibitors (i.e., methimazole or propylthiouracil) in the 24 weeks before screening. 2. Uncontrolled hypothyroidism: defined as initiation of thyroid hormone replacement therapy or dose adjustment of replacement therapy in the 12 weeks before screening. 14.History of myopathies or evidence of active muscle disease demonstrated by CPK ≥ 5 x ULN at screening. 15.Subjects whose ALT, AST, or ALP exceeds by more than 50% on Visit 2 reading compared to Visit 1. Note: If the ALT, AST, or ALP values on Visit 2 exceed by more than 50% from Visit 1, then a third value will be measured (within 1- 2 weeks) to assess for the trend. If the third value shows continued increase ≥ 10%, then subject is considered ineligible for randomization. 16.Any of the following laboratory values at screening: a. Platelets \< 50 × 109/L b. Albumin \< 2.8 g/dL c. eGFR \< 45 mL/min/1.73 m2 d. ALP \> 10 x ULN e.
