NCT ID: NCT00970216 Completed - Chronic Hepatitis B Clinical Trials

Study of Telbivudine in Chronic Hepatitis B

Start date: February 2009
Phase: N/A
Study type: Observational

The purpose of this study is to evaluate the safety, tolerability and antiviral efficacy of telbivudine by maintained suppression of hepatitis B virus (HBV) DNA (<=300 copies/ml or 60IU/ml, undetectable by current polymerase chain reaction (PCR) - based assays) in HBeAg positive/negative patients at physician's general practice.

NCT ID: NCT00964665 Terminated - Chronic Hepatitis B Clinical Trials

Pharmacokinetic/Pharmacodynamic of Albinterferon Alfa-2b in Chronic Hepatitis B, eAg+, Infection Subjects

Start date: July 2009
Phase: Phase 1/Phase 2
Study type: Interventional

This study will assess the efficacy of ABF656 in chronic hepatitis B characterized by HBeAg positivity. The study is designed to establish a dose response and safety relationship sufficient to allow the subsequent design and conduct of Phase 3 trials. The trial is also designed to generate the PK data in hepatitis B patients to satisfy regulatory requirements in China.

NCT ID: NCT00962975 Completed - Clinical trials for Hepatitis B, Chronic

A Study of Pegasys Monotherapy in Patients With Chronic Hepatitis B Who Have Participated in Previous Studies

Start date: September 2009
Phase: Phase 1
Study type: Interventional

In this open-label multicenter study the long-term effect of Pegasys monotherapy on pharmacodynamic HBV-related markers will be investigated in patients with chronic hepatitis B. Eligible patients will have completed treatment on another donor protocol (e.g. PP22512) and will receive Pegasys at an appropriate dose based on the standard of care (180mcg sc once weekly) for up to 48 weeks. Target sample size is <100.

NCT ID: NCT00962871 Completed - Clinical trials for Hepatitis B, Chronic

A Study of Early Immunologic Response in Asian Patients With Chronic Hepatitis B, Treated With Pegasys (Peginterferon Alfa-2a (40KD)), Nucleoside Analogues, or Both

Start date: August 2009
Phase: Phase 1
Study type: Interventional

This open-label, randomized, parallel-arm study will assess the early immunologic response in treatment-naïve Asian male patients with chronic hepatitis B after initiation of treatment with Pegasys or tenofovir or Pegasys plus tenofovir. Patients will be randomized to one of 4 cohorts to receive either Pegasys (360mcg subcutaneously weekly) or tenofovir (300mg orally daily) or both or no treatment for 2 weeks. After 2 weeks on study treatment, patients may opt to receive standard of care treatment with Pegasys. Target sample size is <50.

NCT ID: NCT00962533 Completed - Clinical trials for Hepatitis B, Chronic

EFFicacy Optimization Research of Telbivudine Therapy

EFFORT
Start date: August 2009
Phase: Phase 4
Study type: Interventional

The purpose of this trial is to prove that the strategy of treatment adjustment at W24 according to virological response based on ROADMAP concept is better than standard of care strategy.

NCT ID: NCT00960518 Recruiting - Clinical trials for Hepatocellular Carcinoma

TACE and Adefovir Compared With Transarterial Chemoembolization (TACE) Alone for Hepatitis B Virus (HBV)-Related Unresectable Hepatocellular Carcinoma (HCC)

TACE
Start date: August 2009
Phase: Phase 2
Study type: Interventional

Hepatocellular carcinoma (HCC) is one of the most prevalent malignancies in China, and approximately 90% of the patients with HCC are also infected with hepatitis B virus (HBV). For patients with unresectable disease, the goal of palliative treatment is to control symptoms and prolong survival. Transarterial chemoembolization (TACE) using iodized oil and chemotherapeutic agents combines the effect of targeted chemotherapy with that of ischemic necrosis induced by arterial embolization. It can be administered repeatedly and can prolong survival in patients with unresectable hypervascular HCC. The long-term prognosis, however, remains guarded because of frequent development of locoregional tumor recurrence, which, together with concomitant hepatic decompensation, is the main cause of death. Adefovir works by blocking reverse transcriptase, an enzyme that is crucial for the hepatitis B virus (HBV) to reproduce in the body. Based on these results, the investigators conducted a randomized controlled trial to test the hypothesis that adefovir treatment would reduce or postpone the recurrence rate and improve the overall survival rate in patients after TACE treatment of HBV-related unresectable HCC.

NCT ID: NCT00946010 Completed - Hepatitis C Clinical Trials

Investigation of Hepatitis B and Hepatitis C in Taiwan

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

The purpose of this study is to investigate the differences of genotypes of hepatitis B and hepatitis C in Taiwan.

NCT ID: NCT00940485 Completed - Clinical trials for Hepatitis B, Chronic

A Study of Combination or Sequential Treatment With PEGASYS (Peginterferon Alfa-2a) and Entecavir in Patients With HBeAg Positive Chronic Hepatitis B

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

This 2 arm study will assess the efficacy and safety of Pegasys in combination or sequential treatment with entecavir in patients with HBeAg positive chronic hepatitis B. Patients who have been pretreated with, and responded to, entecavir for 9 to 36 months were randomized to one of 2 groups, to receive Pegasys 180micrograms/week sc for 48 weeks + entecavir 0.5mg po daily for 8 weeks, or entecavir 0.5mg po daily for 48 weeks. The anticipated time on study treatment is 3-12 months.

NCT ID: NCT00939068 Enrolling by invitation - Clinical trials for Chronic Hepatitis B, Gestation

Efficacy and Safety Study of Telbivudine to Prevent Perinatal Transmission

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

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.
