Active clinical trials for "Hepatitis B, Chronic"

The purpose is to evaluate efficacy and safety of therapeutic hepatitis B virus (HBV) vaccine (mimogen-based)) Joint entecavir treatment in chronic hepatitis B patients.

The purpose of this study is to evaluate the efficacy and safety following the Roadmap Concept strategy with an initial monotherapy using either telbivudine or tenofovir in HBeAg negative CHB patients. The data from the study should allow for the validation of the Roadmap concept in a prospective manner, for both telbivudine and tenofovir treated HBeAg negative CHB patients. As part of a post-approval commitment to the European Health Authorities, the data will also be used to provide an optimized clinical treatment strategy for better clinical use of telbivudine in European HBeAg negative patients. Furthermore, the data from the study will contribute to a better scientific understanding, disease management and treatment of HBeAg negative CHB patients.

The purpose of this study is to evaluate the effect of serum hepatitis B virus (HBV) DNA level on intrahepatic recurrence in locally treatable hepatocellular carcinomas (HCCs) related with HBV.

The purpose of the study is to investigate the safety and the antiviral activity of ascending multiple oral doses of LB80380 for 12 weeks in adults with lamivudine-refractory chronic hepatitis B infection.

The aim is to investigate whether Lamivudine 100mg daily is effective in the long term treatment of HBeAg negative chronic HBV infected patients with active liver disease in Asia

This study is to investigate the HBV DNA suppression (and HBeAg seroconversion among HBeAg positive patients) pegylated interferon treatment at 24 weeks after end of treatment among patients who have failed anti-viral treatment in the past.

This study explores the efficacy, safety and tolerability of tenofovir DF (TDF) 300 mg once daily monotherapy versus the combination of emtricitabine 200 mg plus tenofovir DF 300 mg (FTC/TDF) once daily in subjects currently being treated with adefovir dipivoxil (Hepsera) for chronic hepatitis B who have persistent viral replication (detectable hepatitis B virus deoxyribonucleic acid [HBV DNA]). Subjects with confirmed (within 4 weeks) plasma HBV DNA ≥ 400 copies/mL during double blind treatment at Week 24 or any time thereafter have the option of receiving 12 weeks of open-label FTC/TDF which may be continued through the end of the 168-week treatment period if there is a virologic response (HBV DNA < 400 copies/mL). Alternatively, subjects with confirmed HBV DNA < 400 copies/mL at or any time after Week 24 of double-blind treatment may continue blinded therapy up to Week 168 at the discretion of the investigator. If, in the investigator's opinion, it is felt that continued blinded treatment beyond 24 weeks in subjects with confirmed HBV DNA ≥ 400 copies/mL is not beneficial, the subject may discontinue the study and begin commercially available HBV therapy rather than initiate open-label FTC/TDF.

This trial is being conducted as an open-label, extended-term study for patients with chronic hepatitis B who have previously completed an Idenix-sponsored trial with telbivudine.

This primary objectives of this study are to compare the efficacy, safety, and tolerability of tenofovir disoproxil fumarate (TDF) versus adefovir dipivoxil (ADV) for the treatment of pre-core mutant chronic hepatitis B. Participants will receive TDF or ADV for 48 weeks (double-blind). After 48 weeks, eligible participants switched to open-label TDF for up to 480 weeks.

Hepatitis B virus (HBV) infection is a worldwide health problem. It has been proved that the persistence of HBV is associated with the failure to stimulate an efficient HBV-specific immune response. T101, the Chinese counterpart of TG1050, is a replication-defective adenovirus serotype 5 (Ad5) expressing multiple HBV-specific antigens (core, polymerase and envelope) and is used as therapeutic vaccine for chronic hepatitis B patients. The application of T101 aims at inducing a broad HBV-specific cellular immune response and ultimately eliminating HBV infection.
