Study of Tauroursodeoxycholic Acid for Hepatobiliary Disease in Cystic Fibrosis
Recruitment status was Recruiting
OBJECTIVES: I. Determine the optimum dose of tauroursodeoxycholic acid (TUDCA) required to achieve maximal bioavailability for patients with cystic fibrosis-associated liver disease.
II. Compare optimized doses of TUDCA with ursodiol (ursodeoxycholic acid; UDCA) for effects on biliary bile acid composition and metabolism, serum biochemistries, fat absorption, and fat-soluble vitamin status in these patients.
|Study Design:||Endpoint Classification: Efficacy Study
Primary Purpose: Treatment
|Study Start Date:||September 1997|
PROTOCOL OUTLINE: Objective I: This part of the study is a dose-response study to determine the optimal dose of tauroursodeoxycholic acid (TUDCA). Twenty-four patients are randomized to receive one of three different doses of TUDCA for 3 months.
Objective II: This part of the study is a double-blind crossover study to compare optimized doses of TUDCA with optimized doses of ursodiol in 15 patients stratified according to age (less than 10 vs 10-20 vs more than 20 years). Patients are randomized to receive either TUDCA or ursodiol orally for an initial 3 month period, followed by a 3 month washout period in which no drug is administered. Patients then receive the alternate drug for 3 months.
