Filter by: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.
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.
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.
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.
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.
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.
The purpose of this study is to investigate the differences of genotypes of hepatitis B and hepatitis C in Taiwan.
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.
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.
The objective of this study is to provide open label emtricitabine/tenofovir disoproxil fumarate (DF) for an additional 5 years to subjects completing study GS-US-203-0107.
