Health Condition(s) or Problem(s) studied
|
Primary biliary cholangitis (PBC, formerly known as primary biliary cirrhosis) is a serious and potentially life threatening autoimmune disease of the liver characterized by impaired bile flow (cholestasis) and accumulation of toxic bile acids (BA).

Product Name: Seladelpar Product Code: MBX-8025 Pharmaceutical Form: Capsule INN or Proposed INN: SELADELPAR CAS Number: 928821-40-3 Concentration unit: mg milligram(s) Concentration type: equal Concentration number: 10- Pharmaceutical form of the placebo: Capsule Route of administration of the placebo: Oral use
|
Primary Outcome(s)
|
Primary end point(s): 1 - Response on the composite endpoint of AP and total bilirubin at 12 months: o AP < 1.67 × ULN, o = 15% decrease in AP, and o Total bilirubin = ULN 2 - Assessment of treatment-emergent AEs (TEAEs) (National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events [CTCAE] Version 4.0), biochemistry and hematology
|
Secondary Objective: Evaluate the effect of seladelpar on normalization of alkaline phosphate (AP) levels and to evaluate the effect of seladelpar on pruritus. Evaluate the effect of seladelpar on quality of life (QoL), to evaluate the effect of seladelpar on other measures of cholestasis, metabolic outcomes, PBC prognosis criteria, and the effect of seladelpar on PBC clinical outcomes.
|
Main Objective: Evaluate the safety and effect on cholestasis of two seladelpar regimens (5 mg/day titrated to 10 mg/day and 10 mg/day) over 52 weeks of treatment compared to placebo.
|
Timepoint(s) of evaluation of this end point: 1- 12 months 2 - Throughout the study
