What is seladelpar?

Seladelpar (Brand name Livdelzi) is an oral prescription medicine that may be used to treat primary biliary cholangitis (PBC) in adults. Seladelpar 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 seladelpar will improve your chance of survival or prevent liver decompensation.

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

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