Filter by:This observational, multi-center, open-label study will evaluate the prognostic factors of long-term-response and the safety of Pegasys (peginterferon alfa-2a) in patients with HbeAg-negative chronic hepatitis B. Data will be collected for 96 weeks.
The purpose of this study is to determine the durability of seroprotection of HEPLISAV™ and Engerix-B® and the number of injections of each vaccine needed to maintain seroprotection in a cohort of chronic kidney disease (CKD) patients over time.
This study will evaluate the safety and efficacy of tenofovir disoproxil fumarate (TDF) plus peginterferon α-2a (PEG) combination therapy versus standard of care TDF monotherapy or PEG monotherapy in non-cirrhotic adults with chronic hepatitis B virus (HBV). The study will consist of 2 phases for participants in the TDF+PEG 48 week, TDF 48 week+PEG 16 week, and PEG 48 week groups. Following an initial 48 weeks of treatment, participants in these groups will be monitored for 24 weeks for signs of worsening HBV, and those with new signs and/or symptoms will be eligible to receive TDF monotherapy during a retreatment phase, up to Week 120.
Persistent replication of HBV (47-55%) is frequently found in patients with HCC, which in turn leads to deterioration of liver reserve. Moreover, a large proportion of HCC patients who underwent curative therapy died from progressive liver decompensation rather than recurrence of cancer. It had been proved that anti-viral therapy for hepatitis C virus (HCV)-related HCC patients could reduce the rate of tumor recurrence after surgical resection. This is a prospective study to evaluate the efficacy of ETV therapy in chronic hepatitis B patients after receiving RFA therapy for HCC.
No study has reported on the comparative effect of continuing lamivudine plus adefovir versus switching to telbivudine plus adefovir in HBeAg-positive lamivudine-refractory chronic hepatitis B patients who have suboptimal response to lamivudine plus adefovir. The goal of this study is to compare the efficacy of continuing lamivudine plus adefovir versus switching to telbivudine plus adefovir directly in patients with lamivudine-refractory chronic hepatitis B patients who have suboptimal response to lamivudine plus adefovir for at least 12 months.
This is a open, randomized, parallel study. Subjects will have Clevudine or Entecavir therapy for 48 weeks(Clevudine:Entecavir = 2:1), and subjects who have Complete Response(HBV DNA negative and ALT normal) will have follow-up period for additional 48 weeks.
A study to evaluate the efficacy and safety of clevudine and peg-interferon in sequence compared with clevudine alone in the patients with HBeAg(+) chronic Hepatitis B or clevudine and peg-interferon sequential treatment in patients with chronic Hepatitis B who have HBeAg(+)
This is an open study to evaluate the efficacy, safety of clevudine monotherapy or adefovir and clevudine combination in patients with chronic hepatitis B.
An open study to Evaluate the Efficacy, Safety and Sustained effect of Clevudine monotherapy or Adefovir and Clevudine combination in proportion to Roadmap concept in Patients with chronic hepatitis B.
An Open Study to Evaluate the Sustained Effect in Patients Showing Virological Responses With Muscle-related Symptom of Chronic Hepatitis B Patients Who Received Clevudine.
