Primary Sclerosing Cholangitis clinical trials at UC Davis

This study will evaluate the effects of elafibranor (the study drug) in participants with Primary Sclerosing Cholangitis (PSC) during the double-blind period, an initial 96 week open-label extension (OLE) period, and an optional open-label extension long-term (OLE-LT) period beyond OLE Week 96. PSC is a rare disease of the liver that leads to injury and destruction of bile ducts. Damage to bile ducts leads to buildup of bile in the liver, which then causes further damage, and leads to disease progression. This study will compare elafibranor to a placebo, a dummy treatment. The main objective of the trial will be to study the safety and side effects of the study drug, including long-term safety during the open-label extension periods. The trial will also study the study drug's effects on blood tests and other tests related to PSC disease activity.

The purpose of this study is to find out how well and safely elafibranor works compared to placebo in adult participants with Primary sclerosing cholangitis (PSC). PSC is a rare disease that causes inflammation and scarring of the bile ducts in the liver. Over time, this can lead to liver damage and serious health problems, including the need for a liver transplant and death. In this study, about 350 participants with large duct PSC will take part. Participants will be randomized to receive either elafibranor 120 mg once daily or a placebo (a tablet with no active medicine). The study includes a screening period, an treatment period, and a post-treatment safety follow-up. During the study, participants will undergo routine clinical assessments, laboratory testing, imaging evaluations, and complete patient-reassessments to evaluate liver disease progression, symptoms, quality of life and safety. Following the end of treatment, participants will complete a safety follow-up period at approximately four weeks. Participants may withdraw from the study at any time. Each participant may be in the study for several years, as the treatment period will continue until the study reaches enough health events among participants, which is expected to take about 5 years.

The study is designed to assess the safety and efficacy of LB-P8 in patients with primary sclerosing cholangitis.
