Filter by: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.
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
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.
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.
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.
The purpose of this clinical research study is to learn if the study drug entecavir will prevent the recurrence of hepatitis B virus (HBV) in participants who receive an orthotopic liver transplant (OLT) due to HBV infection.
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.
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.
This is an open label, randomized, comparative, multi-center study. Subjects will be screened within 2 weeks prior to study entry to establish eligibility. Subjects who meet all the selection criteria will be randomly assigned 1:1 to (1) once-a-week, subcutaneous Pegylated interferon alfa-2b (PegIntron) (1.5 mcg/kg body weight) or (2) oral adefovir 10 mg daily. The treatment phase will be 24 weeks for PegIntron and 48 weeks for adefovir. All subjects completing the assigned treatment phase will be followed up for an additional 48 weeks for PegIntron and 24 weeks for adefovir as observation phase. The primary objective is to establish the efficacy profile of PegIntron. Secondary objectives are to compare the efficacy profile of PegIntron with that of adefovir, compare efficacy of PegIntron in lamivudine-naïve and lamivudine-experienced subjects, and to establish the safety profile of PegIntron in treating patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B.
The purpose of this clinical research study is to develop observational clinical experience with the use of entecavir in participants who are either of Black/African-American race or of Hispanic ethnicity.
