Active clinical trials for "Hepatic Insufficiency"

A critical issue of the clinical syndrome in liver failure is the accumulation of toxins not cleared by the failing liver. Based on this hypothesis, albumin dialysis is used to remove those substances. Albumin dialysis with recirculation (MARS) is the most used system but required specific system and expert environment. Alternative system without recirculation (SPAD) is less expensive and can be realised in critical care services trained to extrarenal epuration. The primary objective of this study is to compare biological and clinical efficacy, pulsatility index of middle cerebral artery modification and tolerance of both systems. This is a prospective, open, cross-over comparative study of two albumin dialysis system. Each patient will receive the two systems in an randomly assessed order. Patients are divided up according to bilirubin plasmatic level. (250µmol/L to 400 µmol/L and >400µmol/L).

Fulminant hepatic failure (FHF) in children is a potentially devastating disease. The mortality rate may reach 80-90% in the absence of liver transplantation. Liver injury is considered to be mainly immune mediated with augmentation of cytolytic pathways of infected hepatocytes. For that, it is suggested that corticosteroids modulate the activity of the disease by suppressing the immune system.

The primary objective of this study is to investigate the effect of mild (Child-Pugh A, score 5-6) and moderate (Child-Pugh B, score 7-9) hepatic impairment on the pharmacokinetics, safety and tolerability of nintedanib, in comparison with a control group with normal hepatic function following oral administration of nintedanib as single dose.

The primary objectives were: To determine the effects of steady state TPV co-administered with low dose RTV on steady state PegIFN and RBV in HIV negative subjects with mild hepatic impairment (scheme A) To determine the effects of steady state of pegylated interferon (PegIFN) and RBV on steady state pharmacokinetics of TPV co-administered with low dose RTV in HIV negative subjects with mild hepatic impairment (scheme A) To determine the pharmacokinetics of single dose and steady state TPV/r 500/200 mg in subjects with moderate hepatic insufficiency (scheme B)

Assessment of the effect of moderate liver impairment (Child-Pugh classification B) on the pharmacokinetics and pharmacodynamics of dabigatran after oral administration of dabigatran etexilate. Determination of safety and tolerability of dabigatran upon administration to hepatically impaired patients and healthy subjects (matched pairs)

In patients with cirrhosis and liver failure, pro-inflammatory cytokines (TNF alpha) might be responsible of severe complications and death. Thus, the prevention of cytokine production should prevent complications and mortality. The aim of this study is to study the 2 months survival rate in patients with severe cirrhosis (Child-Pugh C) with pentoxifylline - an inhibitor of cytokine production. The 6 month mortality, the proportion of transplanted patients, the occurrence of complications (bacterial infection, renal failure, hepatic encephalopathy and gastrointestinal bleeding), plasma cytokine levels and fibrotest - a marker of fibrosis - will be also studied. This is a multicenter double blind randomized trial with a placebo. All adult patients with severe cirrhosis might be randomized after written consent. Patients with severe carcinoma, intolerance or contraindication to pentoxifylline will not be included. Patients receive either pentoxifylline or placebo 3 times a day for 6 months. Three hundred and forty two patients are necessary to decrease mortality rate by 50% at 2 months in a beta risk of 10% and an alpha risk of 5%. Patients will be seen every month.

This is a non-randomized, open-label, single-dose study to evaluate the pharmacokinetics (PK) of uprifosbuvir (MK-3682), the M5 and M6 metabolites of uprifosbuvir, and ruzasvir (MK-8408), in participants with moderate hepatic insufficiency (HI), participants with severe HI, and age-matched healthy control participants.

This study will determine whether the plasma concentration-time profile and pharmacokinetics (PK) of suvorexant (MK-4305) in participants with moderate and mild hepatic insufficiency are similar to those observed in healthy participants.

The purpose of this study is to determine if treatment with the ELAD Bioartificial Liver Assist Device is beneficial to patients in Acute Liver Failure either as a bridge to liver transplant or bridge to native liver recovery.

This study is investigate the influence of severe hepatic impairment on the pharmacokinetics of acalabrutinib and its metabolite.
