NCT ID: NCT00436163 Completed - Clinical trials for Hepatitis B, Chronic

A Study of PEGASYS (Peginterferon Alfa-2a (40KD)) in Patients With HBeAg-Positive Chronic Hepatitis B (CHB).

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

This single arm study will evaluate the efficacy and safety of PEGASYS in treatment-naive Baltic patients with HBeAg-positive chronic HBV. All patients will receive PEGASYS 180 micrograms s.c. once weekly. Following 48 weeks of treatment, there will be a 24 week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.

NCT ID: NCT00435825 Completed - Clinical trials for Hepatitis B, Chronic

A Study of PEGASYS (Peginterferon Alfa-2a (40KD)) in Patients With Hepatitis Be Antigen (HBeAg) Positive Chronic Hepatitis B (CHB).

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

This 4 arm study will compare the efficacy and safety of PEGASYS given for 24 or 48 weeks, and at doses of 90 or 180 micrograms weekly, in the treatment of HBeAg positive patients with chronic hepatitis B. Patients will be randomized to one of 4 treatment groups: a)PEGASYS 90 micrograms subcutaneous (sc) weekly for 24 weeks, b)PEGASYS 180 micrograms sc weekly for 24 weeks, c)PEGASYS 90 micrograms sc weekly for 48 weeks or d)PEGASYS 180 micrograms sc weekly for 48 weeks. Following treatment there will be a 24 week period of treatment-free follow-up in all treatment groups for the primary endpoint. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.

NCT ID: NCT00423891 Completed - Clinical trials for Hepatitis B, Chronic

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

Start date: June 30, 2007
Phase: Phase 1/Phase 2
Study type: Interventional

The purpose of this clinical study is to determine the appropriate doses of entecavir to use in children and adolescents. Safety, tolerability and efficacy will also be studied

NCT ID: NCT00412750 Terminated - Hepatitis B Clinical Trials

Efficacy and Safety of Telbivudine in Treatment naïve Patients With Hepatitis B e Antigen (HBeAg)-Positive Chronic Hepatitis B (CHB)

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

To evaluate the combination of telbivudine 600 mg orally (PO) once daily and peginterferon alpha-2a 180 ug subcutaneous (sq) injection weekly for antiviral efficacy in comparison to peginterferon alpha-2a monotherapy.

NCT ID: NCT00412529 Completed - Hepatitis B Clinical Trials

Viral Kinetics Study of Telbivudine and Entecavir in Adults With Chronic Hepatitis B

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

This exploratory study is designed to determine the early viral kinetic profile during treatment with telbivudine or entecavir at multiple time points over 12 weeks.

NCT ID: NCT00410202 Completed - Clinical trials for Hepatitis B, Chronic

Entecavir Plus Adefovir Combination Therapy Versus Entecavir Monotherapy vs Therapy With Adefovir Plus Lamivudine for Chronic Hepatitis B Infected Subjects With Lamivudine-resistant Virus

DEFINE
Start date: March 2008
Phase: Phase 3
Study type: Interventional

The purpose of this study is to evaluate the effectiveness of entecavir plus adefovir combination therapy versus entecavir monotherapy or therapy with adefovir plus lamivudine

NCT ID: NCT00410072 Completed - Clinical trials for Hepatitis B, Chronic

Entecavir Plus Tenofovir Combination Therapy Versus Entecavir Monotherapy in Naive Subjects With Chronic Hepatitis B

Start date: April 2007
Phase: Phase 3
Study type: Interventional

The purpose of this study is to compare the effectiveness of entecavir plus tenofovir combination therapy with that of entecavir monotherapy. Safety will also be studied.

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
