You may be eligible if
1. A definite or probable diagnosis of PBC (consistent with American Association for the Study of Liver Diseases \[AASLD\] and European Association for the Study of the Liver \[EASL\] Practice Guidelines, defined as having ≥2 of the following 3 diagnostic factors:
* History of elevated alkaline phosphatase (ALP) levels for at least 6 months
* Positive antimitochondrial antibody (AMA) titer or if AMA negative or low titer (≤1:80), PBC specific antibodies (anti-glycoprotein 210 \[GP210\] and/or anti-SP100) and/or antibodies against the major M2 components (E2 component of mitochondrial pyruvate dehydrogenase complex \[PDC-E2\], 2-oxo-glutaric acid dehydrogenase complex)
* Liver biopsy consistent with PBC (collected at any time prior to Screening)
2. Evidence of cirrhosis including at least one of the following:
* Biopsy results consistent with PBC Stage 4
* Liver stiffness as assessed by Transient Elastography (TE) Median Value ≥16.9 kilopascals (kPa)
* Clinical evidence in the absence of acute liver failure consistent with cirrhosis including: gastroesophageal varices, ascites, radiological evidence of cirrhosis (nodular liver or enlargement of portal vein and splenomegaly)
* Combined low platelet count (\<140,000/cubic millimeter \[mm\^3\]) with
* persistent decrease in serum albumin, or
* elevation in prothrombin time/international normalized ratio (INR) (not due to antithrombotic agent use), or
* elevated bilirubin (2\*upper limit of normal \[ULN\])
3. Satisfy the criteria of the modified Child-Pugh (CP) classification for hepatic impairment during Screening:
* Moderate: CP-B (Scores 7 to 9) or
* Severe: CP-C (Scores 10 to 12)
4. Model of end-stage liver disease (MELD) score of 6 to 24 at Screening
5. Taking ursodeoxycholic acid (UDCA) for at least 12 months (stable dose for ≥3 months) prior to Day 1, or unable to tolerate or unresponsive to UDCA (no UDCA for ≥3 months)
You may not be if
1. Non-cirrhotic or cirrhotic CP-A (Mild; Score 5 to 6)
2. History of liver transplant or organ transplant
3. History of alcohol or drug abuse within 12 months prior to Screening
4. Hepatic encephalopathy (as defined by a West Haven score of ≥2
5. History or presence of other concomitant liver diseases including:
* Hepatitis C virus infection and ribonucleic acid (RNA) positive
* Active hepatitis B infection; however, participants who have seroconverted (hepatitis B surface antigen and hepatitis B e antigen negative) may be included in this study after consultation with the medical monitor
* Primary sclerosing cholangitis
* Alcoholic liver disease
* Definite autoimmune liver disease or overlap hepatitis
* Gilbert's Syndrome
6. In the opinion of the Investigator, fluctuating or rapidly deteriorating hepatic function prior to randomization
