Researchers are studying adults with confirmed Primary Biliary Cholangitis (PBC) and cirrhosis, a scarring of the liver caused by damage to bile ducts. PBC is a slowly progressing disease that causes bile acid buildup and further liver damage, which can lead to cirrhosis. This study aims to evaluate if elafibranor, a daily medication, can prevent worsening clinical outcomes such as the need for liver transplant or death, compared to a placebo. It also looks at the safety of long-term elafibranor use and its effect on symptoms like itching and tiredness. Participants will take either an 80 mg tablet of elafibranor or a matching placebo once daily for up to 3.5 years in a double-blind setup, meaning neither the participants nor researchers know who receives which treatment. This long-term treatment period is designed to monitor the drug's impact over time. The study includes two groups: one receiving elafibranor and the other receiving placebo, with treatment lasting up to approximately 42 months. During the study, participants will be regularly assessed from the start until 4 weeks after treatment ends, with a maximum involvement of 3.5 years. Researchers will measure event-free survival, tracking if participants avoid clinical events indicating disease worsening. Safety monitoring will include tracking side effects and overall health, while symptom impact will be evaluated. Participants will provide informed consent and follow the study protocol throughout this extended observation period.
