Active clinical trials for "Hepatitis"

Chronic hepatitis C virus (HCV) is a major cause of morbidity and mortality worldwide with an estimated number of 180 million infected patients. Until 2012 the current standard of care (SOC) treatment of patients with chronic hepatitis C was a 24 to 72 weeks therapy with pegylated interferon- and ribavirin (PR). In 2012, the protease-inhibitors (PI's) telaprevir and boceprevir as first directly acting HCV drugs have been approved by the local Swiss authority for hepatitis C mono-infected and HCV-HIV-co-infected individuals. However, therapy success is strongly limited in null-responders (NR) to previous PR. Treatment of HCV-HIV co-infected individuals with the new PI's is accompanied by additional challenges (e.g. drug-drug interactions, toxicity, high pill burden). Patients with advanced fibrosis are at highest risk for decompensated liver disease and hepatocellular carcinoma (HCC) and prompt initiation of treatment is strongly recommended. Recently, data in mono-infected patients showed, that in prior non responders a 12 week course of a triple therapy (TT) with telaprevir and PR followed by another 24 weeks of PR resulted in an sustained virologic response (SVR) of only 29%. In HCV-HIV co-infected non-responders with unfavourable preconditions (e.g. HCV-genotype 1, interleukin 28 B non-CC genotype, advanced liver fibrosis, high baseline HCV viral load) SVR after TT is even expected to be lower. These patients urgently need additional therapeutic options with the goal to eradicate HCV in order to prevent further fibrosis progression and to reduce morbidity and mortality. A promising substance in the field of drugs targeting the HCV replication is silibinin. Silibinin is the main component of silymarin, an extract of the milk thistle Silybum marianum. Intravenous silibinin (iSIL) targets multiple steps in the virus life cycle and exhibits anti-oxidant, anti-inflammatory, anti-viral and immunomodulatory properties. iSIL inhibits the HCV NS5B polymerase activity directly or by interfering with the binding of RNA to this enzyme. In addition, iSIL appears to block virus entry, virus transmission and virus secretion.In 2008 Ferenci et al. for the first time reported the substantial clinical antiviral-effect of intravenous silibinin (iSIL) against HCV in PR non-responders. The administration of 20mg/kg iSIL in 20 patients led to a highly significant decrease in viral load. We intend to investigate the effect and tolerability of iSIL in HIV-HCV co-infected individuals with advanced liver fibrosis and previous non- or partial response to SOC. All included study-subjects will receive a lead-in therapy with iSIL in a dosage of 20mg/kg/day (expressed as silibinin concentration) once a day for 14 days. At the end of the THISTLE study, i.e. after the day of completion of the 14-day iSIL administration (day 15), the patients will be considered for eligibility to receive standard of care. We assume that the decline in HCV viral load would substantially improve the chances of SVR as the reduction of viral load should both increase the efficacy of PR and reduce the odds of drug resistance to HCV-specific protease inhibitor. Trial with medicinal product

This is a Phase 1 Open-Label, Parallel-Group, Single-Dose Study to evaluate the Pharmacokinetics of GS-5816 in subjects with normal hepatic function and moderate or severe hepatic impairment.

Hypothesis: the Telaprevir(TVR) plasma levels (750 mg q8h or 1125 mg/12h )will not be affected when co-administered with un-boosted Atazanavir (ATV) 200 mg q12h plus two analogues (NRTIs) in HCV/HIV-co-infected patients.

Background: - Present treatment for hepatitis C includes the use of a weekly injection and two different pills. This treatment is associated with serious side effects. Drugs that can be taken by mouth and cure HCV infection without serious side effects would be a great help to the large number of people infected with HCV. GS-7977 and GS-5885 are new medications being developed to treat the hepatitis C virus (HCV) infection. They are still being researched and are not approved by the Food and Drug Administration. They are being developed as treatment for hepatitis C as a single pill taken once a day. Objectives: - To determine whether a combination of the two study drugs can safely and effectively treat HCV infection in people with HIV infection and who do not have cirrhosis of the liver. Eligibility: - Individuals who have HIV infection and have liver disease caused by infection with HCV. Design: Participants will be screened with a physical exam and medical history. Blood samples will be collected. Urine samples will be collected from participants who might become pregnant. If a participant has not had a liver biopsy in the past 3 years, one will be required. Participants will take one pill daily for 12 weeks. This pill will be a combination of the two study drugs. Treatment will be monitored with frequent clinic visits and blood tests over a total of 60 weeks.

GSK2878175 is a site IV NS5B non-nucleoside inhibitor (NNI) being developed for the treatment of chronic HCV infection. This study represents the first administration of GSK2878175 in humans to define safety, tolerability, and pharmacokinetics (PK) following single and repeat doses of GSK2878175 in healthy subjects. This is a Phase 1, randomized, single-blind, placebo-controlled, dose escalation study to determine the safety, tolerability, and PK profile of GSK2878175 in single (Part 1) and repeat doses (Part 2) in healthy subjects. In addition the study will explore the effect of a moderate (30%) fat meal on single dose PK endpoints in healthy subjects.

Patients with spontaneous decline of HBV DNA were non-randomly assigned to accept peginterferon alfa-2a or entecavir therapy, or didn't accept any antiviral regiment.

Background: - Some people who have chronic hepatitis C do not respond to the usual treatment with peginterferon and ribavirin. New chronic hepatitis treatments are being developed that may work better for different people. The treatments will look at how specific genes interact with the drugs. Researchers want to see how well these new drugs work in people whose chronic hepatitis C has not responded or only partly responded to the usual treatment drugs. Objectives: - To compare new treatments for people with chronic hepatitis C. Eligibility: - Individuals at least 18 years of age who have chronic hepatitis C that has not responded to standard treatments. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Liver scans and a biopsy will be taken before the start of treatment. Participants will be separated into two groups. One group will have the new treatment drugs (assunaprevir and daclatasvir). The second group will have these two drugs as well as peginterferon and ribavirin. All participants will have an initial 4-day hospital stay with regular blood tests to see how the start of the treatment works. The first group will take the new study drug tablets daily for 24 weeks. Those who do not respond to this treatment will also start to take peginterferon and ribavirin, and the treatment will continue for 24 weeks after starting the additional drugs. The second group will take all four drugs according to the standard dosing schedule for 24 weeks. Treatment will be monitored with frequent blood tests. Liver scans, biopsies, and other tests will be performed as directed by the study doctors. Participants will have 24 weeks of regular followup visits.

The purpose of this study is to investigate the efficacy and safety of medical ozone in treatment of chronic hepatitis B patients.

The primary objective of this study is to evaluate the antiviral efficacy of treatment with ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) therapy at the time of liver transplantation and through 4 weeks posttransplant in adults with genotype 1 or 4 hepatitis C virus (HCV) infection who are undergoing primary liver transplantation.

This study is a randomized, placebo controlled, double-blinded clinical trial, which included 50 children with hepatitis A. They were of both sexes and their age ranged from 2 to 18 years. The patients were randomly assigned into one of two groups; each consisted of 25 children. Each patient in the intervention group (group 1) took oral honey in a dose of 5 ml/kg/day (with a maximum dose of 150 ml/day) for four weeks, whereas patients of the placebo group (group 2) took placebo in the form of molasses. The main outcome measure was the recovery time defined as the number of days from the start of the intervention to subsidence of symptoms and signs of hepatitis and return of liver transaminases to their normal levels.
