Active clinical trials for "Hepatitis A"

Different Doses of rosuvastatin and atorvastatin will be used to see if HCV viral load changes and liver tests change.

This is an exploratory study and is a Phase 3, single-arm, multi-center, open-label study of pegylated interferon alfa-2b, PEG-IFN alpha-2b (PEG-Intron) and ribavirin (RBV) to determine the sustained virologic response (SVR) at 24-week follow-up to 48 week in subjects after orthotopic liver transplantation (OLT) with chronic hepatitis C (HCV) recurrence.

This study is designed to test the hypothesis that African-Americans respond less well to combination pegylated interferon and ribavirin therapy than Caucasian-Americans who have chronic hepatitis C genotype 1 and who were not previously treated with either interferon or ribavirin. Reasons for differences in response, regardless of race, will be studied.

This is a prospective, controlled, open-label, pharmacokinetic study. This study aims at studying the PK of ledipasvir, sofosbuvir, and GS-331007 metabolite in HCV infected children with hematological malignancy. In this study, patients in both treatment groups will receive 12 weeks of treatment with a fixed-dose combination tablet containing 45 mg of ledipasvir and 200 mg of sofosbuvir (LDV/SOF) orally, once daily with food.

A total of 2000 chronic hepatitis B (CHB) patients with liver biopsy performed at least 1 year after antiviral therapy are enrolled. All the patients will receive original antiviral treatment for the following 10 years. Patients will be assessed at baseline and at every six months for blood count, liver function test, alpha fetoprotein (AFP), prothrombin time, liver ultrasonography, liver stiffness measurement (LSM), Hepatitis B virus (HBV) DNA and HBV serological markers. HBV-related endpoint events, including cirrhosis decompensations (ascites, esophageal variceal bleeding and hepatic encephalopathy), hepatocellular carcinoma (HCC), liver transplantation and liver-related death, will be collected during follow-up.

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).

The purpose of this trial is to prove that the strategy of treatment adjustment at W24 according to virological response based on ROADMAP concept is better than standard of care strategy.

Hepatitis C is the leading cause of chronic liver disease in industrialized countries, and is the most common indication for liver transplantation. In the Western world, the absolute majority of cases of Hepatitis C Virus (HCV) infection are related to the use of injectable narcotic drugs. Most injecting drug users contract HCV infection within the first years after starting injecting drug use. The aim of this study is to study hepatitis C in a cohort of patients registered in clinics providing maintenance therapy for opiate dependence in three metropolitan areas of Sweden. The cohort is defined as all patients registered in these three clinics at the date of study initiation. The study contains four parts: Part I: the first part of the study aims to evaluate the prevalence of HCV exposure in the cohort and the proportion of anti-HCV positive participants with chronic infection. Part II: Patients with chronic HCV infection will be offered further investigation of chronic liver disease, including liver biopsy, for selection of candidates for antiviral therapy and identification of risk factors for development of severe liver disease. Part III: Based on the results of these investigations, patients will be considered for antiviral therapy. Indications for such therapy will mainly be clinical and/or histological signs of chronic liver disease with fibrosis. All patients will receive weight-based doses of pegylated interferon-alfa-2b and ribavirin. Part IV: Study of pharmacokinetic interactions between ribavirin and opiate substitution molecule (methadone or buprenorphine) in patients receiving antiviral therapy according to part III.

The purpose of this study is to determine whether lozenges of interferon-alpha that are dissolved in the mouth can prevent relapse in patients with hepatitis C virus infection who had a complete virologic response after receiving a combination of injected interferon-alpha and oral ribavirin.

The purpose of the study is to evaluate whether Viusid, a nutritional supplement, reduce the mortality and the complications (ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, hepatic encephalopathy, gastrointestinal bleeding, sepsis and hepatocellular carcinoma) of patients with cirrhosis of the liver secondary to HCV infection in comparison with placebo, during 96 weeks of treatment.
