Active clinical trials for "Hepatitis B, Chronic"

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

To provide open-label entecavir to subjects who have completed previous blinded entecavir trials in Japan and are assessed by the investigator as likely to benefit from additional anti-hepatitis B therapy

The objectives are to demonstrate that entecavir has antiviral activity undetectable HBV DNA measured, the Roche AmplicorTM PCR at Week 48, and to assess the safety and the pharmacokinetic of entecavir in Japanese patients with hepatitis B who have an incomplete response to current lamivudine therapy

The purpose of this study is to determine whether Adefovir Dipivoxil is effective and safe in treatment of Chinese Patients with HBeAg positive Chronic Hepatitis B for 5 years.

The objective of this study is to determine the effectiveness of peginterferon alfa-2b 1.5 mcg/kg/week administered for 52 weeks (wk) in previously untreated participants coinfected with hepatitis virus B and D. After 52-week treatment and 52-week follow-up, the virologic, biochemical, and histological response will be evaluated.

This 3 arm study will assess the efficacy and safety of PEGASYS + entecavir combination therapy in treatment-naive patients with HBeAg positive chronic hepatitis B. Patients will be randomized to receive 1)PEGASYS 180 micrograms s.c./week for 48 weeks, 2)PEGASYS 180 micrograms s.c./week for 48 weeks + entecavir 0.5mg p.o. once daily from week 13 to week 36 or 3) entecavir 0.5mg p.o. once daily for 24 weeks + PEGASYS 180 micrograms s.c./week from week 21 to 68. Treatment will be followed by 24 weeks treatment-free follow up. The anticipated time on study treatment is 3-12 months for groups 1 and 2, and 1-2 years for group 3, and the target sample size is 100-500 individuals.

Compare the safety of four oral doses of pradefovir after 48 weeks of treatment Select the dose of pradefovir for Phase 3 studies

This study was designed to evaluate and compare the safety and tolerability of tenofovir disoproxil fumarate (TDF), emtricitabine (FTC)/TDF, and entecavir (ETV) in the treatment of hepatitis B patients with decompensated liver disease. Safety was assessed by evaluating adverse events (AEs) and laboratory abnormalities. Efficacy was assessed by evaluating reductions in Child-Pugh-Turcotte (CPT) and Model for End Stage Liver Disease (MELD) scores, reductions in hepatitis B virus (HBV) deoxyribonucleic acid (DNA), changes in liver enzymes, development of drug-resistant mutations, and generation of antibody to virus. A maximum randomized treatment duration of 168 weeks was planned. Since subjects with decompensated liver disease were enrolled into this study, it was necessary to provide early intervention strategies if profound viral suppression was not expeditiously achieved. For this reason, subjects with a decrease in plasma HBV DNA from baseline of < 2 log_10 copies/mL and plasma HBV DNA > 10,000 copies/mL (or plasma HBV DNA > 1,000 copies/mL for subjects who entered the study with HBV DNA < 10,000 copies/mL) at Week 8 had the option to start open-label FTC/TDF and continue in the study. Subjects with a virologic breakthrough or who had plasma HBV DNA levels remaining > 400 copies/mL (confirmed) at or after 24 weeks of treatment could have been unblinded at the investigator's discretion for selection of alternative anti-HBV therapy that may have included open-label FTC/TDF. If study drug was permanently discontinued, immediate initiation of another anti-HBV regimen was strongly recommended.

Entecavir, 0.5 mg daily, will have clinical efficacy (assessed as an undetectable hepatitis B DNA, <300 copies/mL, by Roche Comprehensive Bio-Analytical System Amplicor polymerase chain reaction assay) that is comparable (noninferior) and potentially superior to lamivudine, 100 mg once daily, in adults with hepatitis B e antigen-negative chronic hepatitis B virus infection.

This is a phase IV, 2-year, multi-center, single arm and open-label study, evaluating the efficacy and safety with using local manufactured adefovir dipivoxil in Chinese subjects with HBeAg negative chronic hepatitis B
