   required by local law

   2. 18 to 75 years old (inclusive)

   3. Male or female with a diagnosis of PBC, by at least two of the following criteria:

      - History of AP above ULN for at least six months

      - Positive anti-mitochondrial antibody (AMA) titers (>1/40 on immunofluorescence or
      M2 positive by enzyme linked immunosorbent assay [ELISA]) or positive
      PBC-specific antinuclear antibodies

      - Documented liver biopsy result consistent with PBC

   4. On a stable and recommended dose of UDCA for the past twelve months OR intolerant to
   UDCA (last dose of UDCA > 3 months prior to Screening)

   5. AP ≥ 1.67 × ULN

   6. Females of reproductive potential must use at least one barrier contraceptive and a
   second effective birth control method during the study and for at least 90 days after
   the last dose. Male subjects who are sexually active with female partners of
   reproductive potential must use barrier contraception and their female partners must
   use a second effective birth control method during the study and for at least 90 days
   after the last dose

Exclusion Criteria:

   1. Previous exposure to seladelpar (MBX-8025)

   full participation in the study or confound its results (e.g., cancer)

   3. AST above 3 × ULN

   4. ALT above 3 × ULN

   5. Total bilirubin above 2.0 × ULN

   6. Advanced PBC as defined by the Rotterdam criteria (albumin below LLN AND total
   bilirubin above 1 × ULN)

   7. Creatine kinase (CK) above 1.0 × ULN

   8. eGFR below 60 mL/min/1.73 m2 (calculated by MDRD formula)

   9. International normalized ratio (INR) above 1.0 × ULN

10. Platelet count below 100 × 103/µL

11. Presence of clinically significant hepatic decompensation, including:

      - History of liver transplantation, current placement on liver transplantation
      list, or current MELD score ≥ 15

      - Complications of portal hypertension, including known esophageal varices, history
      of variceal bleeds or related interventions (e.g., transjugular intrahepatic
      portosystemic shunt placement), relevant ascites, hepatic encephalopathy

      - Cirrhosis with complications, including history or presence of spontaneous
      bacterial peritonitis

12. Other chronic liver diseases:

      - Current features of auto-immune hepatitis as determined by the investigator based
      on immunoserology, liver biochemistry and histology

      - Primary sclerosing cholangitis determined by presence of diagnostic
      cholangiographic findings

      - History or clinical evidence of alcoholic liver disease

      - History or clinical evidence of alpha-1-antitrypsin deficiency

      - Biopsy confirmed nonalcoholic steatohepatitis

      - History or evidence of Gilbert' Syndrome with elevated total bilirubin

      - History or evidence of hemochromatosis

      - Hepatitis B defined as presence of hepatitis B surface antigen (HBsAg)

      - Hepatitis C defined as presence of HCV RNA

13. Known history of HIV

14. Evidence of significant alcohol consumption

15. Evidence of drug abuse

16. Subjects with inadequate response to obeticholic acid (OCA) or intolerance to OCA: OCA
   must be discontinued 30 days prior to Screening

17. Use of colchicine, methotrexate, azathioprine, or long-term systemic corticosteroids
   (> 2 weeks) within two months prior to Screening

18. Use of fibrates within 30 days prior to Screening

19. Use of simvastatin within 7 days prior to Screening

20. Use of an experimental or unapproved treatment for PBC within 30 days prior to
   Screening

21. Use of experimental or unapproved immunosuppressant within 30 days prior to Screening

22. Treatment with any other investigational therapy or device within 30 days or within
   five half-lives, whatever is longer, prior to Screening

23. For females, pregnancy or breast-feeding

24. Any other condition(s) that would compromise the safety of the subject or compromise
   the quality of the clinical study, as judged by the investigator
