Filter by:Patients with HBeAg negative chronic HBV and evidence of hepatic disease (elevated liver enzymes or evidence of cirrhosis) who have significant viremia are treated with anti HBV therapy. Currently the key goals of anti HBV therapy are profound and prolonged viral suppression and treatment efficacy is assessed by monitoring viral load and liver enzymes. However these do not always reflect the degree of liver impairment or the degree of improvement in response to therapy. Sebivo has been accepted in Israel as a first line therapy for HBeAg negative and HBeAg positive chronic HBV with evidence of liver damage. Viral load should decrease by 1 log every 3 months, otherwise patients should be offered add-on or alternative therapy. As the majority of patients in Israel are HBeAg negative chronic HBV and in order to have homogenous population we will select for our study only patients with HBeAg negative chronic HBV. The 13C Methacetin breath test, assess liver function and specifically the function of the microsomal CYP4501A2. It has been shown to correlate with the degree of liver impairment and with clinical outcomes in both acute and chronic liver disease. The aim of this study is to determine the utility of the 13C Methacetin Breath Test to follow up patients with HBeAg negative chronic HBV receiving anti viral therapy.
This randomized, 2 x 2 factorial, parrallel group study will compare the efficacy and safety of 48 versus 96 weeks of peginterferon alfa-2a [Pegasys], with or without entecavir, in patients with HbeAg negative chronic hepatitis B. Patients will be randomly allocated to receive Pegasys (180mcg subcutaneously weekly) for 48 weeks plus placebo (group A) or entecavir (0,5mg orally daily, group B) during weeks 12-36, or Pegasys (180mcg subcutaneously weekly) for 96 weeks plus placebo (group C) or entecavir (group D) during weeks 12-36. Anticipated time on study treatment is 48 or 96 weeks, with a follow-up of 48 weeks. Target sample size is <500 patients.
Based on 12-week on-treatment data, at least 1 dose of BMS-824393 can be identified which is safe, well tolerated, and has sufficient antiviral activity to progress to late stage clinical trials when combined with pegIFNα/RBV for treatment of chronically infected hepatitis C virus genotype 1 treatment-naive subjects.
In order to persist in the liver, HCV has numerous nonspecific and specific strategies to overcome the immunity of the host. The crucial step in the establishment of viral persistence and chronic hepatitis is the avoidance of specific antiviral cellular immune response in the liver. Treatment with pegylated interferon alpha (IFNα) in combination with ribavirin (RBV) is the standard therapy for chronic hepatitis C is. The response to IFNα / RBV therapy depends on the effective cellular antiviral immune response in the liver. The understanding of the interaction between HCV and cellular immune response is important for the effective use of existing diagnostic techniques, the Individual control and adjustment of the current therapeutic approaches and the development of future therapeutic and immunization strategies. In this study, the investigators want to investigate cellular Immune responses in the liver of HCV infected patients and characterize the influence of these immune responses to the response to IFNα / RBV therapy.
This is an exploratory trial of Bovine Colostrum powder to decrease translocation of gut-derived microbial products and immune activation in HCV infection. The study is designed as a single-arm, open-label, before-and after exploratory trial of 10 weeks of Bovine Colostrum Powder (BCP) to reduce translocation of intestinal microbial products and immune activation in patients suffering from chronic hepatitis C virus (HCV) infection. The study population will include HCV-infected (genotype 1) men and women, ≥ 18 years of age, not receiving anti-viral therapy at the time of enrollment and for at least the previous 3 months. Having failed previous anti-viral therapy (non responders), HCV recurrence after 72 weeks of therapy, developed side effects which mandated stopping anti viral therapy, or not considered eligible for initiation of such treatment, with a plasma HCV RNA level ≥ 1000 I.U.
Hepatitis C is the most common reason for liver transplantation in the United States and affects nearly 4 million Americans. Treatments for hepatitis C are available but are poorly tolerated and are not always effective. Morbidity and mortality from hepatitis C are related to the development and progression of hepatic fibrosis to cirrhosis and end stage liver disease. Efforts to block progression of liver disease would thus result in prevention of morbidity and mortality as well as costs incurred by the health system in the care of these conditions. Scar tissue in the liver is secreted by a type of cell, called the stellate cell, in an activated state. This cell carries a receptor for angiotensin, a hormone, when activated. If this receptor is blocked, the cell becomes inactive and does not participate in scar tissue formation. Thus, we hypothesize that using a drug such as candesartan, which blocks angiotensin receptors, should result in less scar tissue formation in the livers of patients with hepatitis C.
The objective of this pilot project is to investigate the prognostic criteria for sensitivity of Chronic Hepatitis C (CHC) Genotype 1, patients to IFNa treatment. Signal transduction in peripheral blood mononuclear cell (PBMC) of control groups will be compared with that of CHC patients. For this study, 20 patients with Hepatitis C virus (HCV) infection who are to undergo standard antiviral therapy and 10 healthy donors (significant others of the HCV subject) will be enrolled. Signal transduction will be studied in peripheral blood of CHC subjects before the treatment, after 1 and 3 months of treatment, and 4-6 months following the completion of treatment.
The purpose of this study is to investigate the efficacy of telbivudine in Blacks/African Americans and Hispanics/Latinos with compensated chronic hepatitis B during 52 weeks of treatment
Patients with chronic hepatitis B constantly produce the virus in the body. The disease of chronic hepatitis B is the body responding to the virus. Use of steroids can adjust this response. After taking steroids, viral production usually increases and liver function tests increase. After stopping steroids, viral production usually decreases. Many studies in the past have studied taking a low dose steroid before treating hepatitis B. Those studies have shown that low dose steroids help your body to clear the virus. The goal of this study is to improve the liver function by slowing viral growth.
This study examines the effect of telbivudine compared to lamivudine on the early viral kinetics in patients with chronic hepatitis B. The virus Kinetics is measured by the viral load (HBV-DNA) reduction in the serum during the first 12 weeks of therapy.
