NCT ID: NCT00409019 Withdrawn - Chronic Hepatitis B Clinical Trials

Trial of Telbivudine Combination Therapy vs. Continued Adefovir Monotherapy

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

The purpose of this study is to find out if taking a combination of telbivudine and adefovir or tenofovir and telbivudine can lower the amount of Hepatitis B virus in patients that have been taking adefovir alone for at least 5 months and have had less than optimal responses. The safety of taking telbivudine and adefovir together or tenofovir and telbivudine together will also be studied.

NCT ID: NCT00403585 Completed - Chronic Hepatitis B Clinical Trials

Study of Adefovir Dipivoxil for Korean Patients With Chronic Hepatitis B(CHB) Who Have Completed ADF 103814

Start date: July 2006
Phase: Phase 4
Study type: Interventional

This is an open label, single-arm, multi-centre extension study for Korean patients with chronic hepatitis B and compensated liver disease who have completed one-year adefovir dipivoxil treatment in ADF103814. The objective is to assess clinical efficacy and safety of long term (up to 3 years) adefovir dipivoxil 10mg therapy.

NCT ID: NCT00397540 Completed - Chronic Hepatitis B Clinical Trials

The Effect of Viral Load on Intrahepatic Recurrence in Hepatitis B Virus (HBV)-Related Hepatocellular Carcinoma (HCC)

Start date: October 2004
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT00393484 Completed - Chronic Hepatitis B Clinical Trials

A Study in Korea of Entecavir Versus Lamivudine in Adults With Chronic Hepatitis B Infection

Start date: February 2007
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT00388674 Completed - Chronic Hepatitis B Clinical Trials

Study of Entecavir in Patients With Chronic Hepatitis B Virus (HBV) Infection

Start date: December 18, 2006
Phase:
Study type: Observational

The purpose of this study is to prospectively assess the long-term outcomes (benefits and risks) associated with entecavir (ETV) therapy as compared to other antivirals approved for the treatment of chronic HBV infection. For the China substudy, patients randomized to entecavir will have safety and efficacy assessments performed during the first year of the study.

NCT ID: NCT00354653 Completed - CHRONIC HEPATITIS B Clinical Trials

A Trial To Study The Effect Of Lamivudine In Adult Patients Who Suffer From Chronic Hepatitis B Alone

Start date: February 9, 2002
Phase: Phase 4
Study type: Interventional

The efficacy of lamivudine in Hepatitis Be Antigen (HBeAg) positive Asian patients of chronic hepatitis has been well established.The evidence in HBeAg negative patients is limited. Limited sustained response was observed post-treatment following a one year treatment period. Whether these results can be applied to patients in Iran is uncertain. This study is therefore intended to further assess the efficacy profile after two years of open treatment in the adult Iranian population.

NCT ID: NCT00347009 Completed - Cirrhosis Clinical Trials

Adefovir Dipivoxil For The Treatment Of Patients With Chronic Hepatitis B Related Advanced Fibrosis Or Cirrhosis

Start date: May 2005
Phase: Phase 4
Study type: Interventional

This 36-month open-label study of adefovir dipivoxil investigates the clinical benefits of the therapy in chronic hepatitis B patients with advanced fibrosis or cirrhosis confirmed with biopsy. Primary endpoint is histological improvement defined as a decrease of Ishak Fibrosis Score by one point or more from baseline at Month 36 of adefovir dipivoxil treatment. Approximately 150 patients will be recruited in study centres in the Asia Pacific area. The patients are offered 36 months of open label adefovir dipivoxil treatment, with assessments every three months, after which there is a 6-month post study treatment follow-up prior to study completion. After the 36 months of study treatment, it is likely that the patient will benefit from continued treatment with adefovir dipivoxil. If this is the case in the investigators clinical judgement, the investigator should ensure that a routine prescription is available in a timely manner, and that no unnecessary interruption in treatment occurs.

NCT ID: NCT00338780 Completed - Chronic Hepatitis B Clinical Trials

Trial of Lamivudine Treatment in HBeAg Negative Chronic Hepatitis B Patients (in Asia)

Start date: November 2000
Phase: Phase 4
Study type: Interventional

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

NCT ID: NCT00324961 Completed - Chronic Hepatitis B Clinical Trials

Adefovir Dipivoxil Tablets (10mg) In Chinese Subjects With HBe Antigen Negative Chronic Hepatitis B

Start date: January 2006
Phase: Phase 4
Study type: Interventional

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

NCT ID: NCT00316719 Completed - Chronic Hepatitis B Clinical Trials

Adefovir Dipivoxil In Compensated Chronic Hepatitis B Patients

Start date: January 2006
Phase: Phase 3
Study type: Interventional

This study is designed to compare the efficacy and safety of adefovir dipivoxil 10 mg with lamivudine 100 mg in Japanese patients with compensated chronic hepatitis B over 52-week periods.
