What is Livdelzi?

Livdelzi (seladelpar) is an oral prescription medicine that may be used to treat primary biliary cholangitis (PBC) in adults. Livdelzi is:

• Taken in combination with ursodeoxycholic acid (UDCA) in adults who have not responded well to UDCA
• Used alone in patients unable to tolerate UDCA.

It is not known if taking Livdelzi will improve your chance of survival or prevent liver decompensation.

Livdelzi helps manage PBC by activating specific receptors that control key metabolic and liver disease pathways involved in bile acid synthesis, inflammation, and fibrosis; as well as lipid metabolism, storage, and transport. Livdelzi is beneficial for PBC patients because it reduces bile acid production and helps counteract the liver damage caused by the buildup of bile acids.

Livdelzi gained FDA approval on August 14, 2024, under the accelerated approval designation. Continued approval may be contingent on a continued benefit in clinical trials.
