Inclusion criteria

  • Subjects must meet the following criteria to be eligible for study participation:

    1. 18 to 75 years old (inclusive)
    2. Male or female with a diagnosis of PBC based on history
    3. UDCA for the 12 months prior to screening (with stable dose for >3 months prior to screening) OR intolerant to UDCA (last dose of UDCA >3 months prior to screening)
    4. ALP >1×ULN and <1.67×ULN
    5. Females of reproductive potential must use at least 1 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

  • Subjects must not meet any of the following criteria to be eligible for study participation:

    1. Previous exposure to seladelpar (MBX-8025)
    2. A medical condition other than PBC that, in the Investigator's opinion, would preclude full participation in the study (eg, cancer) or confound its results
    3. Advanced PBC as defined by the Rotterdam criteria
    4. Laboratory parameters measured by the Central Laboratory at screening
    5. Clinically important hepatic decompensation
    6. Other chronic liver diseases
    7. Known history of human immunodeficiency virus (HIV) or positive antibody test at screening
    8. Clinically important alcohol consumption, defined as more than 2 drink units per day in women and 3 drink units per day in men, or inability to quantify alcohol intake reliably
    9. History of malignancy diagnosed or treated, active or within 2 years, or ongoing evaluation for malignancy; localized treatment of squamous or noninvasive basal cell skin cancers and cervical carcinoma in situ is allowed if appropriately treated prior to screening
    10. History of drug abuse
    11. Treatment with obeticholic acid or fibrates 6 weeks prior to screening
    12. Treatment with colchicine, methotrexate, azathioprine, or long-term systemic corticosteroids within 2 months prior to screening
    13. Initiation or dose adjustment of anti-pruritic drugs within 1 month prior to screening
    14. Immunosuppressant therapies within 6 months prior to screening
    15. Other medications that affect liver or GI functions, as well as the roux-en-y gastric bypass procedure, may be prohibited and should be discussed with the medical monitor on a case-by-case basis
    16. Treatment with any other investigational therapy or device within 30 days or within 5 half-lives, whichever is longer, prior to screening
    17. Pregnancy or plans to become pregnant, or breastfeeding
    18. 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
