Active clinical trials for "Hepatitis A"

This study will evaluate the efficacy and safety of 4 regimens of PEGASYS plus Copegus, in patients with chronic hepatitis C (CHC) genotype 1 who have failed to respond to previous treatment with standard doses of PEGASYS plus ribavirin. Patients will be randomized to one of 4 groups, to receive a)PEGASYS 360 micrograms/week plus Copegus 1000-1200mg/day, b)PEGASYS 180 micrograms twice weekly plus Copegus 1000-1200mg/day, c)PEGASYS 360micrograms/week plus Copegus 1200-1600mg/day, or d)PEGASYS 180 micrograms twice weekly plus Copegus 1200-1600mg/day. Following 48 weeks treatment, there will be a 24 week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

This exploratory study is designed to determine the early viral kinetic profile during treatment with telbivudine or entecavir at multiple time points over 12 weeks.

The purpose of this study is to evaluate the effectiveness of entecavir plus adefovir combination therapy versus entecavir monotherapy or therapy with adefovir plus lamivudine

A Phase 2, randomized, double-blind, parallel design trial of two doses of mitoquinone mesylate (MitoQ) and of placebo in patients with chronic Hepatitis C. MitoQ is a mitochondria-targeted antioxidant that rapidly permeates the lipid bilayer and accumulates within mitochondria in organs such as liver, brain, heart, skeletal muscle. There is strong evidence for increased oxidative stress and mitochondrial damage leading to apoptosis via caspase activation. Several studies have shown that MitoQ protects cells from apoptosis by acting as a caspase inhibitor and may be effective in reducing cell damage in liver disease. It is hypothesised that administration of MitoQ will lower raised ALT seen in patients with chronic Hepatitis C compared with placebo. Approximately 36 patients who have been unresponsive or not suitable for interferon-based therapy will be enrolled at one centre. Treatment duration will be 28 days with 28 days post-treatment follow-up.

This study represents the first administration of GSK625433 in humans. The study is designed to evaluate initial safety and tolerability in healthy adults as well as anti-viral activity in Hepatitis C(HVC) infected adults. The way the human body processes GSK625433 will also be investigated.

We hypothesize that atorvastatin will decrease HCV viral load in patients taking the medication. Cholesterol is needed for HCV virion production. Cell culture studies have shown that atorvastatin (an HMG-CoA reductase inhibitor) decreases HCV viral replication. As atorvastatin has been proven to decrease heart attack and stroke in patients with high cholesterol, this medication is indicated for the treatment of elevated cholesterol in at risk individuals. Therefore we propose to study the effect atorvastatin has on the viral load of patients initiated on atorvastatin therapy for their elevated cholesterol.

Since a proportion of patients with Acute Viral Hepatitis-B develop severe hepatitis and fulminant hepatic failure, it is logical to believe that a rapid reduction in the HBV DNA levels by using antiviral agents could result in a less intense host response against the hepatitis B virus. However, the experience with lamivudine treatment of immunocompetent patients with AVH-B is limited.The aim of the present study was to evaluate the efficacy, utility and safety of lamivudine in treating immunocompetent patients with AVH-B.

Compare the effectiveness of telaprevir (VX-950) in combination with Pegylated Interferon Alfa 2a (Peg-IFN-alfa-2a) with and without Ribavirin (RBV) in reducing plasma hepatitis C virus (HCV) ribonucleic acid (RNA) levels

The purpose of this trial is to determine the safety, tolerability and effectiveness of KRN7000 for chronic hepatitis B infection.

This is a phase 2, randomized, open-label study comparing the safety, antiviral activity, and pharmacokinetics of HCV-796 administered in combination with peginterferon alfa 2B (Peg-Intron) plus concomitant Rebetol vs. Peg-Intron plus Rebetol in Hepatitis C Virus (HCV) genotype 1-infected subjects who are either naive to treatment or who have previously failed treatment (non-responders).
