View clinical trials related to Hepatitis B.
Filter by:Chronic hepatitis B (CHB) is a serious liver disease worldwide, and the leading cause of cirrhosis and hepatocellular carcinoma (HCC). HBeAg seroconversion is considered to be the satisfied endpoint of antiviral therapy in HBeAg-positive chronic hepatitis B patients. However, HBV reaction, even reverse back to HBeAg positive and clinical relapse could occur in some patients who achieved HBeAg seronconversion by interferon treatment. In this study, the long-term efficacy of interferon therapy in HBeAg positive patients achieved HBeAg seronconversion after interferon treatment and the factors associated with viral and clinical relapse will be observed.
Asses the efficacy and safety of the Anti hepatitis B placenta transfer factor injection in the treatment of HBeAg positive chronic hepatitis B.
This protocol is being conducted to comply with the direct request from the Taiwan Food and Drug Administration (TFDA) for a 60-month intensive pharmacovigilance protocol of patients with known hepatitis B (HBV) or hepatitis C (HCV) infection, regardless of control on antiviral therapy in Taiwan and who are treated with ipilimumab for advanced (unresectable, recurrent or metastatic) Melanoma.
This Phase 1b trial will assess the dose-related safety and PK profile of different doses of NVR 3-778 in patients with chronic hepatitis B. Additionally,changes in patients' serum HBV DNA levels and other virologic efficacy parameters will be assessed.
This is an epidemiologic study on effect of hepatic steatosis on prognosis and outcomes of patients with chronic hepatitis B.
This randomized, multicenter, partially double-blind, placebo-controlled study is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and antiviral effects of treatment with RO6864018 in virologically suppressed participants with chronic HBV infection.
The most important method to slow down and stop the liver disease progression in patients with chronic hepatitis B is antiviral therapy, by which to achieve maintaining viral response during treatment or obtain sustained viral response after treatment. The aim of the therapy with interferon is make patients obtain immune control to HBV defined as sustained viral response after treatment, however, most patients can't get this target after 48 weeks of interferon treatment, and some patients need extended treatment in clinical practice to enhance the rate of sustained viral response or HBsAg loss occurred during treatment. In this cohort study, the efficacy of extended therapy of interferon in HBeAg negative chronic hepatitis B patients will be evaluated.
The most important method to slow down and stop the liver disease progression in patients with chronic hepatitis B is antiviral therapy, by which to achieve maintaining viral response during treatment or obtain sustained viral response after treatment. The aim of the therapy with interferon is make patients obtain immune control to HBV, in clinical practice, it was expressed as HBeAg seroconversion, HBsAg loss and sustained viral response in HBeAg positive patients. However, those targets can't be get in most patients by 48 weeks of interferon treatment, and some patients need extended treatment to enhance the rate of HBeAg seroconversion and HBsAg loss. In this cohort study, the efficacies of extended therapy of interferon in HBeAg positive chronic hepatitis B patients will be evaluated.
The aim of interferon therapy in HBeAg positive chronic hepatitis B was to make patients obtain immune control to hepatitis B virus defined as occurred HBeAg seroconversion and HBsAg loss with sustained viral response after treatment. However this target could not be get if patients keep HBV DNA positive during interferon treatment and offend relapse after withdraw of treatment. In this trail, Nucleoside(acid) analogues(NA) will add on patients with HBV DNA load ≥1000copies/ml after 6 months of interferon treatment, and the efficacies of the combine therapy were evaluated by the rates of HBeAg seroconversion and HBsAg loss after 48 weeks of combined therapy, compared with control group.
The prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) in the United States (US) is relatively low. However, immigrant populations in the US from Asia and sub-Saharan Africa have substantially higher prevalence than the general population and are consequently at a significant risk for hepatocellular carcinoma (HCC). Indeed, the age-adjusted incidence rates for HCC in the US have tripled from 1975 to 2005. As the population demographics have changed, the 2000 US census estimated the number of Somalis in Minnesota at 25,000 but current estimates put the number at around 50,000 due to primary refugee arrivals as well as secondary immigration from other states. There is no available data for Somali immigrants in the US on HBV and HCV prevalence, HBV and HCV genotypes/subgenotypes, and genetic and immunologic risk factors predisposing Somalis to HBV and HCV and the subsequent development of HCC. Therefore. this study will fill these gaps in the Somali population to understand the relative importance of HBV and HCV infections in causation of HCC. Besides Somalis, Minnesota is also home to large other African immigrant communities. According to the Minnesota Department of Health (MDH), in 2013, the highest rates of chronic HBV cases where reported among Asian or Pacific Islanders (3,638 cases per 100,000 persons) followed by Black or African Americans (2,078 cases per 100,000 persons). Additionally, Minnesota receives a large number of new refugee's resettlement. It is important to improve the identification of chronic HBV and HCV infections among Somali refugees and immigrants in Minnesota through well-designed community-wide screening efforts. Since we know that African immigration to Minnesota is the third highest in the US, this unique population might be a contributing factor to the increased burden of hepatitis and liver cancer complications in the state of Minnesota. Findings from HBV and HCV screening among Somalis suggest that other immigrant African populations from high viral hepatitis endemic regions, such Ethiopia, Liberia, and Kenya, are also at substantial risk of HBV, HCV and HCC. Unfortunately, very little research has been conducted in the US on the burden of hepatitis and liver cancer in African Immigrants from areas of high endemicity of hepatitis B and hepatitis C. Therefore, the goal of is to identify HBV and HCV and the role viral genetics and immune response among African immigrant communities from Kenya, Liberia, and Ethiopia.
