Active clinical trials for "Hepatitis B, Chronic"

To investigate the influence of hepatic steatosis on the anti-viral effect of entecavir in chronic hepatitis B patients.

Adefovir add-on therapy is superior to switching to adefovir monotherapy or entecavir 1mg monotherapy for chronic hepatitis B (CHB) patients with lamivudine resistance (LAM-R) Long-term adefovir add-on therapy was effective for viral suppression. However, the economic burden for such dual antiviral therapy is heavy because of infinite treatment. Tenofovir disoproxil fumarate (TDF) is a potent antiviral agent. TDF demonstrated potent antiviral efficacy in a subset of lamivudine experienced HBeAg-positive patients. TDF is also superior to ADV in HBeAg-negative and HBeAg-positive treatment-naive patients. Theoretically, TDF can replace LAM/ADV when viral suppression has been achieved by LAM/ADV combination treatment in LAM-R CHB patients.

The purpose of the study is to evaluate the effects and safety of Adefovir Dipivoxil plus polyene phosphatidylcholine compared to Adefovir Dipivoxil alone in patients with chronic hepatitis B.

The purpose of this study is to verify the effectiveness and safety of medical ozone therapy system in treatment of chronic hepatitis B.

This study is designed to evaluate the safety of biological active dose of a new experimental drug, IL-7, in combination with anti viral therapy and vaccine in patients with Hepatitis B chronic infection.

Open-label, prospective, two part study evaluating IFN-γ 1b at a dose of 200μg by subcutaneous injection every day either alone or in combination with Adefovir dipivoxil or Adefovir dipivoxil alone at a dose of 10mg QD in patients with chronic Hepatitis B.

The purpose of this study is to evaluate the efficacy and safety of Telbivudine in pregnancy for the prevention of HBV perinatal transmission in highly viraemic mothers.

The investigators' pilot study indicates that hepatitis C virus (HCV)- and hepatitis B virus (HBV)-coinfected patients with predominantly active hepatitis C and those with predominantly active hepatitis B may need different anti-viral regimens. Since in the majority of these coinfected patients the hepatitis activity is more likely due to HCV than to HBV, the optimal therapeutic regimen for HCV- and HBV-coinfected patients with predominantly active hepatitis C will first be investigated. The combination therapy using pegylated interferons (IFNs) such as PEG-IFN alfa-2a has been shown to have a superior efficacy than that using conventional IFN in the treatment of monoinfected chronic hepatitis C. This new combination therapy might also further enhance the treatment efficacy in HCV- and HBV- coinfected patients. The investigators therefore propose to initiate a trial comparing the efficacy of pegylated IFN plus ribavirin (RBV) in dual chronic hepatitis B and C versus that in chronic hepatitis C only, for both HCV genotype 1 and 2/3 patients. The efficacy using a 24-week combination therapy in the sustained clearance of serum HCV RNA is equivalent to that using a 48-week combination therapy in patients with HCV genotype non-1 [Hadziyannis et al, EASL 2002]. A 48-week course of pegylated IFN and RBV combination therapy, in contrast, has been shown to yield a better efficacy in the sustained clearance of serum HCV RNA in patients with HCV genotype 1 than a 24-week combination therapy in western countries [Hadziyannis et al, EASL 2002; Poynard et al, 1998]. The primary objective of the current proposal is to investigate and compare the efficacy of combination therapy using pegylated IFN plus RBV on the clearance of serum HCV RNA in both dually infected patients with a dominant HCV infection and HCV monoinfected patients. Therefore, in this proposal, the treatment duration will be 24 weeks for HCV genotype 2/3 in patients with dual chronic hepatitis C and B and in patients with monoinfected HCV, and will be 48 weeks for HCV genotype 1 in patients with dual chronic hepatitis C and B and in patients with monoinfected HCV.
