Fortunately, the PBC treatment landscape has evolved, and new treatments with novel mechanisms of action are available for patients with inadequate response to UDCA, but questions remain. Different treatment strategies have emerged in recent years from major societies across the globe regarding treatment targets, timing of treatment response assessment, management of hepatic and extrahepatic manifestations, and choice of second-line therapies.

Nine international PBC experts, representing the United States, Canada, Europe, Asia, Africa, and Central/South America, collaborated to formulate opinions about the unanswered questions related to treatment targets in PBC.
