Filter by:The West African Treatment Cohort for Hepatitis B (WATCH) study is a component of the European Commission Funded FP7 project PROLIFICA. It aims to evaluate a number of steps required to successfully treat patients with chronic hepatitis B virus infection to prevent cirrhosis and liver cancer. The first step is to determine whether screening for hepatitis B using a point of care test is feasible and effective. The second is to monitor linkage from screening into care. The third is to evaluate cheap non-invasive assessments to determine the need for treatment. The fourth is to determine what proportion of patients meet treatment eligibility criteria. The fifth step is to establish a treatment cohort which can be used to measure adherence to therapy and avoidance of HBV related complications. A parallel untreated cohort will be established to determine whether treatment criteria are relevant in this West African setting by monitoring for complications of HBV infection.
This study aims to determine the prevalence of HBV infection in patients with IBD and rheumatologic disease, and to assess the impact of immunosuppressive therapy on viral load and clinical course of IBD patients.
An exploratory clinical trial to evaluate the pharmacokinetic characteristics of I.V. Hepabig injection used for prevention of hepatitis B relapse after liver transplantation.
This Phase 1 trial will assess the dose-related safety and PK profile of different doses of NVR 3-778, first in healthy volunteer subjects (part I) and subsequently in patients with chronic hepatitis B (part II). Additionally, in Part II, changes in patients' serum HBV DNA levels and other virologic efficacy parameters will be assessed.
A randomized, Open label, Single center, Prospective study to compare efficacy and safety of Therapeutic Vaccination with Intensified schedule plus Pegylated Interferon dual Therapy on Seroclearance of Hepatitis B virus Surface Antigen in Patients with Complete Virological Response Induced by Entecavir
To evaluate the effectiveness and safety of tenofovir for different treatment duration in preventing HBV relapse in patients with malignancies after receiving chemotherapy and off-treatment of chemotherapy.
It is estimated that 350-400 million people have chronic infection with hepatitis B virus (HBV) all over the world. In china, 93 million individuals suffer from this chronic condition. Currently, seven medications are approved for the treatment of hepatitis B: two formulations of interferon and four nucleos(t)ide analogues. The Chinese population has one of the longer average life spans, and the size of the aged population has been increasing rapidly. As a result, the prevalence of elderly patients with HBV has increased, and the potential for development of cirrhosis or hepatocellular carcinoma in such patients is real. Hence, treatment of elderly patients with HBV is an important issue. However, ADV or ETV has become first choice due to the more side effect of INF and the resistant of LAM and LdT. But treatment outcomes with ADV and ETV in elderly are not known yet. In this study, we will evaluate and compare the efficacy and tolerability of ADV and ETV between younger and older patients with HBV. The aims of the present study are (1)to assess the benefits of ADV or ETV therapy for elderly patients with chronic hepatitis B, and (2)to determine differences in the emergence rate of side effect.
This will be a multi-center study in Hong Kong. This is a retrospective-prospective study in HBeAg-negative chronic hepatitis B patients. HBeAg-negative patients on entecavir followed up in the liver clinics will be identified from the existing database. All patients had HBV DNA testing every 6 months as a clinic routine. Serum HBsAg levels will be tested in the residual serum samples at the pre-treatment and last follow-up visits. Eligible patients will be discussed on the plan of stopping entecavir therapy. All patients will have written informed consent before recruited into this study. All patients will be followed up for 12 months after stopping entecavir treatment. As entecavir is most commonly used antiviral drug in Hong Kong and in the Western countries, the investigators aim to investigate and validate the use of serum HBsAg quantification to guide the timing of stopping entecavir in HBeAg-negative patients. The results of this study will provide scientific evidence on the use of this new serum marker to predict sustained remission after stopping entecavir. In the long-run, it can improve patient compliance, reduce the need of long-term antiviral and reduce the drug cost in the management of HBeAg-negative chronic hepatitis B. All patients will stop entecavir according to the Asian Pacific guideline with written informed consent and close subsequent monitoring. In the protocol, there is a safety net for re-treatment. There will not be any invasive procedure. There is no major ethical issue.
This is a multi-center, single-arm, open-label study on the virological response of chronic HBV infection to pegyinterferon-alfa-2a among patients who achieved HBeAg seroconversion on nucleos(t)ide analogue (NA) treatment. The primary endpoint of this study is to investigate the sustained response (HBeAg seroconversion with HBV DNA <2000 IU/ml) to peginterferon at 24 weeks after the end of treatment.
The purpose of this study is to determine whether ARC-520 in combination with entecavir is effective in the treatment of patients with chronic HBV Infection.
