Study of Seladelpar and Cilofexor in Participants With Primary Biliary Cholangitis
A Phase 2 Proof-of-Concept Study With a Randomized, Double-Blind, Placebo-Controlled Period, Followed by an Active Treatment Extension Period to Assess the Safety and Efficacy of Seladelpar and Cilofexor in Combination for Primary Biliary Cholangitis
The goal of this clinical study is to learn more about the combination of study drugs seladelpar and cilofexor. The study will assess, the safety, tolerability, and effectiveness of the combination drugs versus both seladelpar alone and placebo, in participants with primary biliary cholangitis (PBC).
The primary objective of this study is to determine whether the combination of seladelpar + cilofexor leads to greater alkaline phosphatase (ALP) reduction than seladelpar alone and describe the safety and tolerability of seladelpar + cilofexor.

-
Have a diagnosis of primary biliary cholangitis (PBC) as defined by a history of any 2 of the following criteria:
- ALP above 1.0 × the ULN for at least 6 months
- Positive antimitochondrial antibody titer (> 1:40 on immunofluorescence or M2 positive by enzyme-linked immunosorbent assay) or positive PBC-specific antinuclear antibodies
- Documented liver biopsy results consistent with PBC
-

-
Have an ALP ≥ 1.67 × ULN at screening
-
Have a negative serum pregnancy test at screening
Key Exclusion Criteria:
- Have other causes of liver disease including viral, alcoholic, autoimmune, and metabolic associated steatohepatitis (MASH).
- Cirrhosis with Child-Pugh Score ≥ 7, corresponding to Class B or C. Individuals with compensated cirrhosis (ie, Child-Pugh Class A) are allowed if they meet all other criteria.

- Have previous exposure to seladelpar or cilofexor
- Used obeticholic acid, fenofibrate, bezafibrate, elafibranor, pemafibrate, or saroglitazar within 6 weeks (42 days, inclusive) of screening date
- Require or expect to require treatment with ≥ 5 mg prednisone (or systemic equivalents) for > 2 weeks during the study
- Are on any systemic drug for antipruritic treatment that has required a dose adjustment in the 30 days before screening, or initiated a systemic antipruritic drug in the 30 days before screening
Note: Other protocol defined Inclusion/Exclusion criteria may apply.

실험적: Seladelpar (SEL) 10 mg + Placebo-to-Match (PTM) Cilofexor (CILO) Dose A + CILO Dose B
Participants will receive a dose of SEL 10 mg capsule along with PTM CILO Dose A tablets and CILO Dose B tablets, once daily up to 24 weeks. At completion of Week 24, participants will continue in an Active Treatment Extension (ATE) Period, during which they will receive SEL 10 mg along with either CILO Dose A or Dose B at the original randomized dose in a blinded fashion, up to Week 312. |
