Filter by:Currently, peginterferon alfa-2a or oral nucleos(t)ides are approved for the treatment with HBeAg positive CHB, with the overall HBeAg seroconversion far from satisfactory. Therefore, efforts on the various combinations with the currently available drugs are needed to improve the overall response rates. The simultaneous combination therapy with oral nucleoside and peginterferon alfa-2a from large-scaled randomized trials did not show a superior response rate over peginterferon alfa-2a monotherapy. Recently, sequential monotherapy with lamivudine for the first 4 weeks, followed by weekly peginterferon alfa-2a has shown favorable HBeAg seroconversion rate over peginterferon alfa-2a monotherapy, based on the assumption that early viral suppression by lamivudine can restore the immune function to facilitate the later immunomodulatory response by peginterferon alfa-2a. With the recent introduction of entecavir, the more potent oral nucleoside with few drug resistance, sequential monotherapy with entecavir can potently suppress HBV DNA with 4 weeks of treatment, which may facilitate the response of peginterferon alfa-2a to achieve HBeAg seroconversion. Therefore, we aimed to conduct a placebo controlled randomized control trial to evaluate of adding entecavir early in the course of therapy can improve the treatment response.

Furthermore, prior studies using 24 months of standard interferon alfa showed better ALT normalization and HBV suppression rates to 12 months of therapy. With the recent introduction of entecavir, the more potent oral nucleoside with few drug resistance, sequential monotherapy with entecavir can potently suppress HBV DNA with 4 weeks of treatment, which may facilitate the response of peginterferon alfa-2a to achieve HBV viral suppression. Therefore, we aimed to conduct a placebo controlled randomized control trial to evaluate if adding entecavir early in the course of therapy or extending the treatment duration of peginterferon alfa-2a can improve the treatment response.
This is a Phase I, open-label, single-dose study to evaluate the pharmacokinetics and safety of LDT600 in pediatric and adolescent patients with chronic hepatitis B infection.
The purpose of this study is to determine if treatment with intramuscular hepatitis B virus immune globulin Grifols, a new specific hepatitis B immune globulin, is effective and safe for the prevention of hepatitis B virus recurrence after orthotopic liver transplantation.
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.
Treatment with a nucleoside analogue and subsequent viral decline has shown to partially restore immune hyporesponsiveness in chronic hepatitis B patients. Recent pilot studies investigating whether the effect of lowering viral load with nucleoside analogue therapy prior to the initiation of peginterferon results in higher sustained off-treatment responses showed contradictory findings. The aim of this study is to investigate sustained off-treatment response to peginterferon alfa-2b in chronic HBeAg-positive hepatitis B patients who are pretreated with nucleos(t)ide analogues, thereby lowering viral load
The purpose of this study is to investigate whether it is possible to augment the response of patients with HBeAg-positive chronic hepatitis B to entecavir by using a temporary peginterferon alpha-2a add-on strategy
The purpose of this trial is to provide data of absence of inflammation in patient liver histology after long-term telbivudine treatment and thus help investigators to make a comprehensive judgment on treatment discontinuation in selected patients
The purpose is to evaluate efficacy and safety of therapeutic Hepatitis B Virus（HBV） vaccine (mimogen-based) treatment in chronic hepatitis B patients and to explore the most effective dosage and provide the rational for optimal dosing schedule.
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
