Pilot study: fenofibrate for patients with primary biliary cirrhosis and an incomplete response to ursodeoxycholic acid

Aliment Pharmacol Ther 2011; 33: 235–242 Summary Background Newer therapies are needed for patients with primary biliary cirrhosis and incomplete response to ursodeoxycholic acid (UDCA). Fenofibrate is a fibric acid postulated to regulate immune response and cell proliferation. Aim To evaluate the efficacy and safety of fenofibrate in patients with primary biliary cirrhosis and incomplete response to UDCA. Methods We undertook a pilot study involving 20 patients with primary biliary cirrhosis and serum alkaline phosphatase (ALP) ≥ 2× ULN. Nonparametric statistical tests and Spearman correlation test were used as appropriate. Results Twenty patients received fenofibrate (160 mg/day) in addition to UDCA for 48 weeks. Median serum ALP decreased significantly at 48 weeks compared with baseline values [351 (214–779) U/L at baseline vs. 177 (60–384) U/L at 48 weeks, P
