FDA approves Ocaliva for rare, chronic liver disease
On Friday, May 27, the U.S. Food and Drug Administration granted accelerated approval for Ocaliva (obeticholic acid) for the treatment of primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults with an inadequate response to UDCA, or as a single therapy in adults unable to tolerate UDCA.
PBC is a chronic, or long lasting, disease that causes the small bile ducts in the liver to become inflamed, damaged and ultimately destroyed. This causes bile to remain in the liver, which damages the liver cells over time, and results in cirrhosis, or scarring of the liver. As cirrhosis progresses, and the amount of scar tissue in the liver increases, the liver loses its ability to function.
Ocaliva, given orally, binds to the farnesoid X receptor (FXR), a receptor found in the nucleus of cells in the liver and intestine. FXR is a key regulator of bile acid metabolic pathways. Ocaliva increases bile flow from the liver and suppresses bile acid production in the liver, thus reducing the exposure of the liver to toxic levels of bile acids.
