2. Participated in a PBC study with seladelpar
3. 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: Exclusion criteria are only applicable for subjects with a seladelpar interruption greater than 4 weeks prior to Day 1 of this study and for subjects who participated in CB8025-21838 irrespective of seladelpar interruption.
1. Treatment-related adverse event (AE) leading to seladelpar discontinuation in a previous PBC study with seladelpar (MBX-8025)
2. A medical condition, other than PBC, that in the investigator's opinion would preclude full participation in the study or confound its results (e.g., cancer)
3. AST or ALT above 3 × the upper limit of normal (ULN)
4. Total bilirubin above 2 × ULN
5. MELD score ≥
12. For subjects on anticoagulation medication, evaluation of the baseline INR, in concert with any current dose adjustments in anti-coagulant medications, will be taken into account when calculating this score. This will be done in consultation with the medical monitor.
6. Evidence of advanced PBC as defined by the Rotterdam criteria: albumin below 1× the lower limit of normal (LLN) AND total bilirubin above 1 × ULN)
7. eGFR ≤45 mL/min/1.73 m2 (calculated by MDRD formula)
8. Auto-immune hepatitis
9. Primary sclerosing cholangitis
10. Known history of alpha-1-antitrypsin deficiency
11. Known history of chronic viral hepatitis
12. For females, pregnancy or breast-feeding
13. Use of colchicine, methotrexate, azathioprine, or long-term use of systemic steroids (e.g. prednisone, prednisolone, budesonide) (>2 weeks) within 2 months prior to Screening
14. Current use of fibrates or use of fibrates within 3 months prior to Screening

16. Use of an experimental or unapproved treatment for PBC within 3 months prior to Screening
17. History of malignancy diagnosed or treated, actively or within 2 years, or active evaluation for malignancy; localized treatment of squamous or non-invasive basal cell skin cancers and cervical carcinoma in-situ is allowed if appropriately treated prior to Screening
18. Treatment with any other investigational therapy or medical device within 30 days or within 5 half-lives, whatever is longer, prior to Screening
19. 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
20. Immunosuppressant therapies (e.g., cyclosporine, tacrolimus, anti-TNF or other immunosuppressive biologics)
21. Other medications that effect liver or GI functions such as absorption of medications or the roux-en-y gastric bypass procedure may be prohibited and should be discussed with the medical monitor on a case-by-case basis
22. Positive for:
1. Hepatitis B, defined as the presence of hepatitis B surface antigen
2. Hepatitis C, defined as the presence of hepatitis C virus ribonucleic acid (RNA)
3. Human immunodeficiency virus (HIV) antibody
