Trial ID or NCT#
A 52-week, placebo-controlled, randomized, Phase 3 study to evaluate the safety and efficacy of seladelpar in subjects with primary biliary cholangitis (PBC) and an inadequate response to or intolerance to ursodeoxycholic acid (UDCA) The participants might enter the ongoing open-label safety study (NCT03301506) following this double-blind study.
A 52-week, Placebo-controlled, Randomized, Phase 3 Study to Evaluate the Safety and Efficacy of Seladelpar in Subjects With Primary Biliary Cholangitis (PBC) and an Inadequate Response to or an Intolerance to Ursodeoxycholic Acid (UDCA)

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
- 1. Previous exposure to seladelpar (MBX-8025) 2.

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.

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.

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
