An Efficacy Trial of Low Dose All-trans Retinoic Acid (ATRA) in Patients With Primary Sclerosing Cholangitis
The purpose of this research study is to determine whether a low dose of ATRA will improve
laboratory tests of liver and bile duct inflammation in patients with PSC. The investigators
will also look for changes to other blood tests which are related to inflammation, scarring,
and the immune system.
