Active clinical trials for "Liver Failure"

We have completed patient enrollment in the the double blind, randomized, placebo-controlled trial of intravenous (IV) N-acetylcysteine (NAC) vs. placebo for the treatment of non-acetaminophen ALF. The purpose of this study is to examine the safety and efficacy of intravenous NAC in children with ALF for whom no antidote or other specific treatment is available. Inclusion in the NAC Study required enrollment in the Pediatric Acute Liver Failure (PALF) Study Registry.

OBJECTIVES: I. Determine the safety and efficacy of a short course (72 hours) of intravenous acetylcysteine in patients with acute liver failure for whom no antidote or specific treatment is available.

The primary objective of this trial is the evaluation of safety and tolerability in patients with mild to moderate hepatic impairment [Child-Turcotte-Pugh (CTP) classification A and B] over different dose regimes of BI 685509 compared to placebo. A secondary objective is to investigate pharmacokinetics of different doses of BI 685509 in patients with mild to moderate hepatic impairment (CTP A and CTP B). In addition, another secondary objective is to compare safety, tolerability, and pharmacokinetics in patients with mild to moderate hepatic impairment (CTP A and CTP B) of single BI 685509 dose to individually matched healthy volunteers

To provide proof-of-concept data on the efficacy/safety of transplanting HCV positive donor grafts in HCV sero-negative liver recipients who are currently listed.

Early postoperative extracorporal liver support therapy (ELS) as a tool to manage post hepatectomy liver failure (PLF). Post-operative liver failure (PLF) has been identified as a major risk factor leading to increased morbidity and mortality. The incidence of PLF varies largely between 0-30%, and may be accounted for the main reason of postoperative mortality related to liver surgery (reported figures ranging from 18 to 75 %). Currently, there are only a few treatment options for PLF, mainly restricted to the treatment of complications like bile leakage, infections as well as the prevention of further liver damage caused by e.g. thrombosis or haemorrhage as well as administration of liver toxic drugs. Recently the international study group on liver surgery (ISGLS) published criteria for a new definition of PLF which will greatly facilitate the comparison of results from future studies on a variety of aspects on liver failure. ELS by using the Molecular Adsorbent Recirculating System (MARS) is based on a modified haemodialysis that allows the removal of water-soluble and protein bound toxins over an albumin-coated high flux membrane against recycled exogenous albumin. Thus, MARS can support the compromised detoxification capacity of the liver as well as improve physiological parameters. This would offer the potential for temporary support for the harmed liver after liver resection allowing for a more uneventful recovery. For obvious reasons previous reports contain few patients, present heterogonous treatment groups and all suffer from lack of standardized treatment protocols. Few if any surviving patients, thus providing no evidence to encourage ELS as a possible treatment option for patients suffering of PLF. However, studies with defined patient populations and treatments according to a predefined standardised treatment protocol are warranted. Primary issues to be addressed: Can ELS be applied in an early phase of PLF? Is ELS safe and feasible for the treatment of PLF when practised according to a predefined protocol? Secondary issues to be addressed: The development of predictive laboratory-chemical markers of liver failure Indirect measures of portal flow and portal pressure Indocyanine green clearance (ICG) under ELS treatment Clearance of toxic products as assessed in aliquots taken from the dialysate

All the children with acute liver failure who are candidates for transplant but have constraints for transplant will be randomized either to receive standard medical therapy or high volume plasma exchange along with standard medical therapy with the aim to assess the effect of high volume plasma exchange on transplant free survival.

This study consists of Part I and an optional Part II. The purpose of Part I is to compare the plasma pharmacokinetics of verubecestat (MK-8931) following administration of a single oral dose of 40 mg MK-8931 to participants with moderate hepatic insufficiency (HI) to that of healthy matched controls. An interim safety and pharmacokinetic analysis on the basis of Part I will be performed in order to support the decision to continue with the optional Part II. If a decision to continue with Part II is made, participants with mild HI will be enrolled to receive a single oral dose of 40mg MK-8931. If any healthy participants from Part I do not meet the matching criteria for Part II additional healthy participants will be enrolled.

This study is designed to evaluate the safety and pharmacokinetics of zanubrutinib in subjects with impaired liver function in comparison with healthy subjects

To determine the pharmacokinetics of single-dose and steady-state Tipranavir/Ritonavir (TPV/r) 500/200 mg in subjects with mild to moderate hepatic insufficiency

This open-label, non-randomized study was designed to compare pharmacokinetics of a single 50 milligram (mg) dose of MK-0822 in participants with and without moderate hepatic insufficiency (abnormal liver function) in order to determine to what degree hepatic dysfunction may impact therapeutic blood levels of MK-0822. The primary hypothesis is that plasma AUC0-∞ of odanacatib in participants with moderate hepatic insufficiency is similar to that in matched healthy participants following a single 50 mg oral dose.
