NCT ID: NCT00962442 Completed - Alcoholic Hepatitis Clinical Trials

N-Acetylcysteine in Severe Acute Alcoholic Hepatitis

Start date: September 2000
Phase: Phase 3
Study type: Interventional

Acute alcoholic hepatitis (AAH) is the most severe form of alcoholic liver disease (ALD) and is associated with a high risk of dying in the short term. Corticosteroids are generally recommended in patients with severe AAH, but its use is still controverted and contraindicated in case of active infection or gastrointestinal bleeding. Therefore, alternative therapeutic options are needed.Ethanol consumption results in the depletion of endogenous antioxidant capabilities and patients with ALD have evidence of antioxidant deficiencies.Due to its effects on glutathion stores restoration and as such the limitation of the oxidative stress and its good tolerance and safety profile, N-acetylcysteine (NAC) is an attractive agent for the treatment of AAH.In this context, we hypothesized that NAC might be beneficial in severe AAH.

NCT ID: NCT00959699 Completed - HIV Infections Clinical Trials

A Phase 2b, Safety and Efficacy Study of Boceprevir in Patients Coinfected With HIV and Hepatitis C (P05411 AM4)

Start date: November 2009
Phase: Phase 2
Study type: Interventional

The primary objective of this trial is to compare the efficacy of boceprevir (SCH 503034) 800 mg three times a day (TID) orally (PO) in combination with peginterferon alfa-2b (PegIFN-2b) 1.5 µg/kg weekly (QW) subcutaneously (SC) plus weight-based dosing (WBD) of ribavirin (RBV) (600 mg/day to 1400 mg/day) PO to therapy with PegIFN-2b + RBV alone in adult participants coinfected with human immunodeficiency virus (HIV) and previously untreated chronic hepatitis C virus (HCV) genotype 1. Boceprevir is a potent, orally administered, novel serine protease inhibitor, specifically designed to inhibit the HCV nonstructural protein 3 (NS3) protease and, thereby, inhibit viral replication in HCV-infected host cells. The mechanism of inhibition represents a new mechanism of action compared to both interferon alfa and ribavirin. Based on previous experience with PegIFN-2b and RBV in combination with boceprevir in the HCV-monoinfected population, this combination treatment is expected to provide significant benefit to the HIV/HCV coinfected population. Given the high unmet medical need of these participants and the benefit of the addition of boceprevir to PegIFN-2b/RBV, it is important to demonstrate the safety and efficacy of boceprevir in combination with PegIFN-2b/RBV in participants coinfected with HIV/HCV. This is a randomized, multi-center trial, double-blinded for boceprevir or placebo in combination with open-label PegIFN-2b/RBV in participants coinfected with HIV and previously untreated chronic HCV (genotype 1), to be conducted in conformance with Good Clinical Practice (GCP). This trial consists of two arms, one control arm (Arm 1) and one experimental arm (Arm 2). Participants in the control arm (Arm 1) may receive boceprevir/PegIFN-2b/RBV via a crossover arm.

NCT ID: NCT00959166 Completed - HIV Infections Clinical Trials

To Assess Neuroinflammation and Neurocognitive Function in Patients With Acute Hepatitis C and Chronic HIV Co-Infection

Start date: June 2009
Phase: N/A
Study type: Interventional

This study plans to evaluate what happens to the brain in patients with HIV and early hepatitis C. The investigators will be comparing 3 groups of individuals: - Group 1: Individuals with HIV infection and acute (early) hepatitis C infection - Group 2: Individuals with HIV infection - Group 3: Healthy volunteers

NCT ID: NCT00948220 Completed - Clinical trials for Hepatitis C, Chronic

Influence of Antiviral Therapy on Bone Mineral Density and Metabolism in Patients With Chronic Hepatitis C

Start date: July 2003
Phase: Phase 4
Study type: Interventional

One single study has suggested that bone mineral density (BMD) is reduced in patients with non-cirrhotic chronic viral hepatitis C. Antiviral combination therapy with standard interferon and ribavirin may further decrease BMD. The aim of this study is to systematically investigate the effect of chronic hepatitis C genotype 1 infection alone and current standard therapy with peginterferon alfa-2a/ribavirin on BMD and bone metabolism.

NCT ID: NCT00946010 Completed - Hepatitis C Clinical Trials

Investigation of Hepatitis B and Hepatitis C in Taiwan

Start date: April 2008
Phase: N/A
Study type: Observational

The purpose of this study is to investigate the differences of genotypes of hepatitis B and hepatitis C in Taiwan.

NCT ID: NCT00945880 Completed - Hepatitis C Clinical Trials

Safety and Tolerability Study of Clemizole Hydrochloride to Treat Hepatitis C in Subjects Who Are Treatment-Naive

CLEAN-1
Start date: July 2009
Phase: Phase 1
Study type: Interventional

The purpose of this study is to test the hypothesis that clemizole hydrochloride is safe and well tolerated when administered to subjects who are infected with hepatitis C virus and have not yet received treatment. This study will also examine how the virus and body respond to clemizole hydrochloride.

NCT ID: NCT00944684 Completed - Chronic Hepatitis C Clinical Trials

High Dose Ribavirin in the Treatment of Chronic Hepatitis C

Start date: November 2007
Phase: Phase 2
Study type: Interventional

Treatment of patients with chronic hepatitis C infected with genotype 1 hepatitis C virus (HCV) consists of combined peginterferon/ribavirin for 48 weeks. Approximately 50% of patients experience sustained virological response which equals cure. All other patients either do not respond or experience recurrence of HCV virus and chronic hepatitis. Important predictors of successful treatment are sustained dosing of both peginterferon and ribavirin. With regard to the latter, clinical evidence indicates that higher ribavirin doses may in fact even improve treatment outcome. However, high ribavirin doses cause hemolytic anemia which require dose reductions. Recent clinical experience show that erythropoetic growth factors, including erythropoetin, can counteract hemolytic anemia caused by antiviral treatment in chronic hepatitis C patients. Therefore, the current trial aims to test whether higher ribavirin doses adapted to a target plasma concentrations instead of a weight-based dosing result in better healing rates, and whether ribavirin-associated hemolytic anemia can be compensated by concommitant erythropoetin treatment. Using a randomized, controlled, open-label design, the investigators hypothesize that patients with high ribavirin doses adapted to plasma levels experience better viral clearance than patients treated with standard weight-based ribavirin doses. In addition, the investigators hypothesize that erythropoetin treatment will counteract hemolytic anemia induced by ribavirin thereby allowing maintenance of target plasma concentrations without ribavirin dose reductions.

NCT ID: NCT00943761 Completed - Clinical trials for Hepatitis C, Chronic

A Study of Vaniprevir (MK-7009) in Participants With Chronic Hepatitis C Infection After Participation in Other Vaniprevir Studies (MK-7009-028)

Study type: Interventional

This study will provide vaniprevir 600 mg or 300 mg twice daily in combination with pegylated interferon (peg-IFN) and ribavirin (RBV) to participants with chronic hepatitis C virus (HCV) infection who did not achieve viral eradication while participating in a prior vaniprevir clinical trial (MK-7009-004, NCT00518622; MK-7009-007, NCT00704405; MK-7009-009, NCT00704184; and MK-7009-029, NCT00954993).

NCT ID: NCT00940420 Completed - Clinical trials for Hepatitis C, Chronic

A Study of Combination Treatment With Pegasys (Peginterferon Alfa) and Copegus (Ribavirin)in Patients With Chronic Hepatitis C

Start date: October 2002
Phase: Phase 4
Study type: Interventional

This 2 arm open-label study will assess the safety and tolerability of combination treatment with Peginterferon alfa (Pegasys) and Ribavirin (Copegus) in patients with chronic hepatitis C. Patients will be assigned to receive Peginterferon alfa (Pegasys) 180 mcg sc once a week and Ribavirin (Copegus) 800 - 1200 mg po daily for either 24 or 48 weeks. Allocation to the treatment arms is to the discretion of the investigator (mainly according to genotype). Adverse events will be monitored throughout the study and hematologic parameters every 2 weeks and twice during the 24-week follow-up.
