NCT ID: NCT00781105 Completed - Chronic Hepatitis B Clinical Trials

Efficacy and Safety of Telbivudine 600mg Tablets in Chinese Patients With Chronic Hepatitis B

Chinese PAC
Start date: August 1, 2008
Phase: Phase 4
Study type: Interventional

The "Chinese PAC" study (CLDT600ACN03) will evaluate the efficacy and safety of open label telbivudine in 2,200 compensated Chronic Hepatitis B (CHB) adults. The primary objective of the study is the proportion of patients achieving undetectable HBV DNA at week 52.

NCT ID: NCT00778596 Recruiting - Chronic Hepatitis B Clinical Trials

Prednisolone Priming Study in Patients With Chronic Hepatitis B

Start date: February 2009
Phase: Phase 4
Study type: Interventional

Study purpose: To investigate whether ALT rebound following corticosteroid priming enhances response to telbivudine therapy. Efficacy assessments: The primary endpoint will be the 1-year HBe-Ag seroconversion rate with or without prednisolone priming. Data analysis: A summary table will be presented as frequency tables for categorical variables as number, and percentage, whereas descriptive tables for continuous variables as number, mean ± SD and median (minimum, maximum). All statistical assessments will be two-sided and evaluated at significance level of 0.05. Continuous variables will be analyzed using t-test, or ANOVA, and categorical variables will be analyzed using chi-square or Fisher's exact test. A non-parametric method, Wilcoxon rank-sum or sign-rank tests will be conducted for continuous, and categorical variables if data is far from normal distribution.

NCT ID: NCT00753467 Not yet recruiting - Hepatitis B Clinical Trials

A Phase II Study to Determine the Safety and Efficacy of Interferon-gamma in Patients With Chronic Hepatitis B

Start date: September 2008
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT00736190 Completed - Chronic Hepatitis B Clinical Trials

A Study to Evaluate Tenofovir Disoproxil Fumarate (DF) in Asian-American Adults With Chronic Hepatitis B Infection

Start date: August 2008
Phase: Phase 4
Study type: Interventional

The purpose of this study is to evaluate the antiviral activity and safety of tenofovir disoproxil fumarate (TDF) in Asian-American adults (self-reported Asian descent, living in the United States) with chronic hepatitis B infection. All participants will receive active treatment with TDF for 48 weeks.

NCT ID: NCT00734162 Completed - Clinical trials for Hepatitis B Virus (HBV)

Evaluation of Tenofovir Disoproxil Fumarate in Adolescents With Chronic Hepatitis B Infection

Start date: December 2008
Phase: Phase 3
Study type: Interventional

The primary purpose of the study is to evaluate the effectiveness, safety, and tolerability of tenofovir disoproxil fumarate (TDF) in adolescents (aged 12-17 years) with chronic hepatitis B virus (HBV) infection. The optimal treatment for adolescents with chronic HBV infection is currently unknown. Treatment with interferon alfa, lamivudine, and adefovir dipivoxil in pediatric populations has been shown to be less than optimal. Further, the safety and efficacy of entecavir and telbivudine have not been established in patients < 16 years of age. A study evaluating TDF in adolescents (ages 12-17) was needed to assess the safety and efficacy of this agent in the treatment of chronic hepatitis B in this patient population. In addition, the study will help to further elucidate the pharmacokinetic (PK) and resistance profiles of TDF. Through their participation, study participants will help generate critical new information to help guide the most optimal treatment of chronic HBV infection in adolescents. This is a randomized, double-blind study to evaluate the antiviral efficacy, safety, and tolerability of TDF versus placebo in adolescents with chronic HBV infection. One hundred TDF treatment-naive participants were randomized in a 1:1 ratio to TDF or placebo. After 72 weeks of blinded treatment, all participants were to switch to open-label TDF for an additional 2.5 years of treatment, provided that no safety concerns are identified by the Independent Data Monitoring Committee monitoring the study.

NCT ID: NCT00720668 Recruiting - Clinical trials for Hepatocellular Carcinoma

The Risk of Exacerbation of Chronic Hepatitis B After Percutaneous Radiofrequency Ablation of Hepatocellular Carcinoma

HBV-HCC
Start date: June 2006
Phase: N/A
Study type: Observational

This study aim to find out the risk of exacerbation of chronic hepatitis B after percutaneous radiofrequency ablation (RFA) or hepatectomy for HCC, and it's effect to treatment outcome.

NCT ID: NCT00718887 Completed - Clinical trials for Hepatitis B, Chronic

Suboptimal Responders to Adefovir Switching to Entecavir

Start date: July 2008
Phase: Phase 4
Study type: Interventional

Switching to Entecavir will result in superior antiviral efficacy as compared to continuing with Adefovir in patients with a suboptimal response to Adefovir

NCT ID: NCT00715715 Withdrawn - Chronic Hepatitis B Clinical Trials

Efficacy Study of Prednisone Priming to Treat Asian Chronic Hepatitis B Patients

Start date: April 2008
Phase: N/A
Study type: Interventional

Patients with chronic hepatitis B constantly produce the virus in the body. The disease of chronic hepatitis B is the body responding to the virus. Use of steroids can adjust this response. After taking steroids, viral production usually increases and liver function tests increase. After stopping steroids, viral production usually decreases. Many studies in the past have studied taking a low dose steroid before treating hepatitis B. Those studies have shown that low dose steroids help your body to clear the virus. The goal of this study is to improve the liver function by slowing viral growth.

NCT ID: NCT00710216 Withdrawn - Clinical trials for Hepatitis B, Chronic

Comparison of Telbivudine Versus Lamivudine on the Early Dynamics and Kinetics of Viral Suppression in Chronic Hepatitis B

EVD
Start date: n/a
Phase: Phase 4
Study type: Interventional

This study examines the effect of telbivudine compared to lamivudine on the early viral kinetics in patients with chronic hepatitis B. The virus Kinetics is measured by the viral load (HBV-DNA) reduction in the serum during the first 12 weeks of therapy.

NCT ID: NCT00686790 Completed - Clinical trials for Hepatitis B, Chronic

Efficacy of Peginterferon Alfa-2b in Previously Untreated Subjects With Chronic Hepatitis B and D Co-infection (Study P04603)

Start date: December 2005
Phase: Phase 3
Study type: Interventional

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.
