3. For at least 90 days after study drug administration, non-vasectomized males must not donate sperm, be willing to use contraception with childbearing potential partners and any male subject with a pregnant partner must use a condom.
4. Willing to abstain from consuming grapefruit, pomelo, star fruit, or Seville orange containing products from 7 days prior to dose of study medication through day of discharge.
5. Confirmed diagnosis of PBC with evidence of cirrhosis and Child-Pugh classification of CP-A, CP-A + PHT, CP-B or CP-C
6. Screening laboratory parameters:
   • ALP, ALT and AST < 10 × ULN
   • Total bilirubin ≤ 5 × ULN
7. Ursodeoxycholic acid (UDCA) for a minimum of 12 weeks of treatment prior to Day 1
8. At screening confirmed diagnosis of PBC
9. MELD-Na scores of 6 to 24

1. Clinically significant or history of acute or chronic liver disease of an etiology other than PBC
2. Patients with a diagnosis of overlapping PBC and autoimmune hepatitis
3. History, evidence, or high suspicion of hepatobiliary malignancy based on imaging, screening laboratory values, and/or clinical symptoms.
4. Presumptive or diagnosed infection that requires systemic therapy within 12 weeks of Screening and through Day 1
5. Female subjects who are pregnant or nursing
6. Screening ECG that demonstrates a QT interval ≥ 500 msec, or any other significant ECG finding with clinically significant abnormalities as determined by the Investigator
7. Positive for HBsAg, HCV RNA, or anti HIV antibody
8. Any non-hepatic acute or chronic condition that, in the opinion of the Investigator, would limit the patient's ability to complete and/or participate in the study or compromise the integrity of the data

9. Has experienced an illness that is considered by the Investigator to be clinically significant within 2 weeks before administration of investigational product

   10. Clinically relevant drug or alcohol abuse within 6 months of Screening. A positive

   drug screen will exclude subjects unless it can be explained by a prescribed medication

   11. Use of obeticholic acid (OCA), any drug of the same class, or fibrates (e.g.,

   bezafibrate, fenofibrate, elafibranor, lanifibranor, pemafibrate, saroglitizar) within 30 days of Baseline

   12. Use of an experimental or unapproved treatment for PBC within 30 days of Baseline 13. Clinically evident complication(s) of cirrhosis and portal hypertension that required

   either emergency room visit, hospital admission or both during the 12 week period prior to investigational product administration
