Boxed Warning Ordered for Intercept’s Ocaliva

FDA has ordered a Boxed Warning on Intercept Pharmaceuticals’ liver disease drug Ocaliva (obeticholic acid) after determining that it is being incorrectly dosed daily instead of weekly in patients with moderate to severe primary biliary cholangitis (PBC), a rare chronic liver disease, increasing the risk of serious liver injury. The agency is also requiring a Medication Guide to inform patients prescribed the drug, according to a safety alert. The alert follows an earlier notice 9/2017 (see story).

 

FDA notes that Ocaliva has been shown to improve a certain blood test that measures liver problems in patients with PBC.  It works by increasing bile flow and suppressing bile acid production in the liver, reducing the liver’s exposure to toxic bile levels. Progressive PBC can lead to liver failure or death.
