Active clinical trials for "Cholestasis"

The purpose of this study is to determine whether ursodiol is effective in the treatment of parenteral nutrition associated cholestasis in neonates.

Double blind, randomized, placebo controlled, Phase 3 study to investigate the efficacy and safety of low doses and high doses of A4250 compared to placebo in children with progressive familial intrahepatic cholestasis (PFIC) types 1 and 2.

The primary objectives of the study are to evaluate the safety, tolerability and pharmacokinetics of A4250 after single or multiple oral doses in healthy subjects. In addition, will evaluate A4250 in combination with cholestyramine.

Biliary anastomotic strictures (post liver transplantation) occur in 15-20 % of the cases. Biliary stenting using plastic prosthesis during a period of 1 year is the treatment of choice. Problematic in this approach is the regular change, necessary to overcome occlusion of the stent, resulting in cholestasis and/or infection. This change needs to be performed every 3 months or more frequently in patients with symptoms of stent occlusion. The Kaffes stent (RMS) is a metallic removable stent, especially constructed for the treatment of biliary anastomotic strictures post liver transplantation. The advantage could be that this stent is less prone to occlusion with a lower change frequency (e.g. every 6 months). No randomized, controlled trial (RCT) or data exist comparing plastic stenting versus Kaffes stenting.

The purpose of this study is to determine whether Omegaven is effective in the treatment of parenteral nutrition associated liver disease (PNALD).

The purpose of this study is to investigate the feasibility and safety of endoscopic ultrasound-guided biliary drainage with a newly designed hybrid metallic stent.

The purpose of this study is to determine whether the omega-3 fatty acid emulsion (Omegaven®), when used in place of the conventional soy-based fat emulsion (Intralipid), is effective in treating parenteral nutrition associated liver disease (PNALD) in children. The study hypothesis is that Omegaven® can be safely provided to children who are dependent on parenteral nutrition and have PNALD, and can reverse or prevent progression of PNALD until the child can take adequate nutrition by mouth.

Though ursodeoxycholate acid (UDCA) is the well known effective therapy for PBC,clinical effectiveness of UDCA may be limited by its poor absorption and extensive biotransformation.The more hydrophillic bile acid tauroursodeoxycholate (TUDCA) is the active ingredients of UDCA,and has been approved by state food and drug administration in China for treatment of cholesterol stones.So it is necessary to verify the efficacy and safety of TUDCA in the treatment of adult primary biliary cirrhosis. In this randomized, double-blinded, double -dummy, parallel-controlled and multicenter clinical trial, we detect the proportion of patients who had AKP decline more than 25% as the primary outcome;decline of ALP,total bilirubin, GGT,ALT and AST as secondary outcomes after patients were treated with TUDCA or UDCA for 24 weeks.

This will be a randomized, double-blind, placebo-controlled study to assess safety and tolerability of GSK2330672 administration in subjects with primary biliary cirrhosis (PBC) and symptoms of pruritus. It is a double-blind, crossover study with subjects receiving placebo or GSK23306772 in random order during two 14-day treatment periods. Additionally, the study will determine GSK2330672 exposure and interactions with ursodeoxycholic acid (UDCA). The total duration of subject participation will be 14 weeks for screening (45 days) and the treatment period. Subjects who are eligible for enrolment will participate in a 2-week placebo run-in period. Subjects will be randomized in a crossover fashion (Sequence 1 / Sequence 2) to receive placebo or GSK2330672 treatment during two consecutive 2-week study periods. Subjects will then participate in a 2-week placebo dosing follow-up period ending in final follow-up assessments. Study results will be utilized to form a benefit: risk profile for GSK2330672 in PBC that will determine plans for progression to exploratory efficacy trials

Cannulation of (placement of a small catheter into) the bile duct is critical to remove bile duct stones, divert bile leaks, and decompress biliary obstruction due to cancer. Given the small size of the bile duct orifice and its close proximity to the pancreatic duct, selective biliary cannulation is the most difficult part of the endoscopic retrograde cholangiography (ERCP). New small diameter sphincteromes and "short wire" systems (which allow physicians to control guidewires) offer potential, though untested advantages. At most hosptial both the long and short wire systems as well as small versus standard are routinely used for clinical care. Our hypothesis is that small diameter, physician controlled wires favor biliary cannulation Our objective will be to assess whether small diameter sphincterotomes and "short wire" physician controlled guidewire cannulation favors successful bile duct cannulation and minimize complications.
