About

The participants of this study will have confirmed Primary Biliary Cholangitis (PBC) with inadequate response or intolerance to ursodeoxycholic acid (which is a medication used in the management and treatment of cholestatic liver disease).

PBC is a slowly progressive disease characterized by damage of the bile ducts in the liver, leading to a buildup of bile acids which causes further damage. The liver damage in PBC may lead to scarring (cirrhosis).

PBC may also be associated with multiple symptoms. Many patients with PBC may require liver transplant or may die if the disease progresses and a liver transplant is not done.

This study has two main parts; the first part will compare a daily dose of elafibranor (the study drug) to a daily dose of placebo (a dummy treatment), and will last between a minimum of one year and a maximum of two years. In the second part, all participants will receive elafibranor, for a period between 4-5 years.

The main aim of this study is to determine if elafibranor is better than placebo at decreasing the levels of a specific blood test (alkaline phosphatase) that provides information about participant's disease. This study will also study the safety of long-term treatment with elafibranor, as well as the impact on symptoms such as pruritus and fatigue.

Exclusion Criteria:

  • History of alcohol abuse
  • For female patients: known pregnancy or lactating
  • Use of fibrates and glitazones within 2 months prior to screening
  • Use of OCA, azathioprine, cyclosporine, methotrexate, mycophenolate, pentoxifylline, budesonide and other systemic corticosteroids (parenteral and oral chronic administration only); potentially hepatotoxic drugs
  • (including α-methyl-dopa, sodium valproic acid isoniazid, or nitrofurantoin) within 3 months prior to screening

  • For patients with previous exposure to obeticholic acid (OCA), OCA should be discontinued 3 months prior to screening
  • Patients who are currently participating in, plan to participate in, or have participated in an investigational drug study or medical device study containing active substance within 30 days or five half-lives, whichever is longer, prior to screening; for patients with previous exposure to seladelpar, seladelpar should be discontinued 3 months prior to screening
