Active clinical trials for "Hepatitis B"

The purpose of the study is to investigate the long-term safety and the antiviral activity of the optimal doses of LB80380 for additional 48 weeks in treatment-naive patients with chronic hepatitis B infection compared to entecavir 0.5 mg.

The outcome of treatment of chronic hepatitis B is determined by viral and host interaction, thus the combination therapy of immunomodulator (PEG-IFN) and potent antiviral drug (entecavir) should improve the response rate. In addition, the simultaneous assessment of viral and host genetic factors associated with SVR may help to identify predictors of treatment outcomes, which will in turn significant reduce the cost/effect of therapy

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.

Antiviral treatment on Chronic Hepatitis B (CHB) patients with liver cirrhosis is compulsory and effective. Telbivudine, which is superior to lamivudine in the treatment of CHB,is considered to be appropriate for the antiviral treatment on CHB patients with liver cirrhosis.

The purpose of this study is to elucidate the influence of anti-hepatitis B virus therapy on safety and survival of HCC patient after transcatheter arterial chemoembolization.

Most hepatocellular carcinomas are associated with hepatitis B virus, it is hypothesized that anti-viral treatment may be helpful in treating HBV-related hepatocellular carcinoma.

Compared to nucleoside/nucleotide analogues, peginterferon alfa 2a/2b may has more therapeutic efficacy in hepatitis B surface antigen or e antigen seroconversion and anti-tumor occurrence in chronic hepatitis b patients. We design this study to investigate treatment of peginterferon alfa 2a/2b in anti-virus treatment experienced patients with HBV related liver fibrosis.

A research study to observe the safety, efficacy and tolerability of switching from Tenofovir Disoproxil Fumarate to Besifovir dipivoxil maleate in patients with chronic hepatitis B

This is an open label, randomized, multi-center, comparative study. Subjects will be screened prior to study entry to establish eligibility. 60 Subjects who meet all the selection criteria will be randomly assigned to (A) QL007 200mg BID+ Tenofovir dipirofurate fumarate （TDF）300 mg QD, (B) QL007 200 mg BID+ Entecavir 0.5 mg QD, (C)TDF 300 mg QD, (D) Entecavir 0.5 mg QD. The purpose of this study was to evaluate the efficacy and safety of QL-007 tables in combination with TDF or Entecavir in patients with chronic hepatitis b who have received nucleoside (acid) therapy, and to recommend a reasonable regimen for phase III study.

Chronic HBV infection is major problem in Asian countries. Years after chronic infection, in some cases serum HBsAg level declines to unmeasurable level. Some of patients develop anti-HBsAb but there is no standard treatment to accelerate HBsAg seroconversion. There is a study to determine efficacy and safety of HBV vaccine in who is Chronic HBV infection and lost their HBsAg without seroconversion to anti-HBsAb.
