To explore the antiviral effect of nucleoside analogue in late pregnancy and the safety of the antiviral drug to fetus.To establish the best therapy strategy to pregnant women with high level of HBV DNA.

NCT ID: NCT01787279 Completed - Clinical trials for Hepatitis B, Chronic

An Expanded Access Study of Pegasys (Peginterferon Alfa-2a) in Patients With HBeAg-Negative Chronic Hepatitis B

Start date: January 2006
Phase: Phase 4
Study type: Interventional

This is an expanded access programme to make Pegasys (peginterferon alfa-2a) available to patients with HBeAg-negative chronic hepatitis B in Morocco. Patients will receive Pegasys 180 mcg subcutaneously weekly for 48 weeks and efficacy and safety will be recorded during treatment and for 24 weeks of follow-up.

NCT ID: NCT01782794 Completed - Hepatitis B Clinical Trials

Acceptability of Hepatitis B Vaccination in General Population

PopCorn
Start date: May 2009
Phase: N/A
Study type: Observational

The present study is conducted in order to assess the acceptability of Hepatitis B vaccination in French general population before and after reimbursement of the paediatric vaccine InfanrixHexa. Four measurements are planned, first before reimbursement and the others at year 1, 2 and 3 after reimbursement.

NCT ID: NCT01777295 Completed - Hepatitis B Clinical Trials

Development of Read-outs in Healthy, Hepatitis B Virus Naive Adults Vaccinated With the Hepatitis B Surface Antigen (HBsAg) in Combination With a GlaxoSmithKline (GSK) Biologicals' Adjuvant System

Start date: February 25, 2013
Phase: Phase 2
Study type: Interventional

This study aims to develop innovative immunological read-outs and new technologies in order to further characterise the early immune response and its kinetics as well as the adaptive immune responses to adjuvanted vaccines. This study will also evaluate the reactogenicity in healthy, hepatitis B virus naive adults vaccinated with the hepatitis B surface antigen in combination with a GSK Biologicals' Adjuvant System.

NCT ID: NCT01777074 Completed - Hepatitis B Clinical Trials

Acceptability of Hepatitis B Vaccination in General Practitioners and Paediatricians

PRALINE
Start date: November 2009
Phase: N/A
Study type: Observational

The present study is conducted in order to assess the acceptability of Hepatitis B vaccination in French general practitioners and peadiatricians before and after reimbursement of the paediatric vaccine InfanrixHexa. Two data measurement time points are planned, first before reimbursement and after reimbursement.

NCT ID: NCT01772121 Completed - Hepatitis C Clinical Trials

Observational Study on Prevalence of Host and Viral Genotypes in Chronic Hepatitis B and Hepatitis C Patients in India

Start date: May 2012
Phase: N/A
Study type: Observational

This study will define the substantial disease burden associated with viral hepatitis in India, and provide a foundation to understand the host and viral determinants of disease pathogenesis that may ultimately impact treatment decisions and outcome

NCT ID: NCT01767597 Completed - Hepatitis B Clinical Trials

Application of HBV Rapid Tests as a Tool for Wide-Use Screening

OPTISCREEN-B
Start date: February 2012
Phase: N/A
Study type: Interventional

With over 280 000 chronic carriers, 2,500 new annual cases and 1,300 deaths each year, hepatitis B is currently a frequent and potentially severe disease in France, despite efforts towards prevention and effective care. In terms of prevention, France has very low immunization coverage (27.7%) and a high percentage of people ignoring HBV status (55%), leading to a delay in care. This is partly explained by poor knowledge of hepatitis B infection in the general population and an underestimation of the health impact of hepatitis B by doctors and health officials. Until recently, there have been no national guidelines governing its implementation (which is variable depending on the structures where screening is performed) and an insufficient evaluation of screening practices. Thus, data on the severity of liver disease, indications for treatment of HBV-infected patients and data on the use of vaccination for nonimmunized people are scarce. Furthermore, while HIV rapid tests are beginning to be used more widely, particularly to address the issue of people who do not come back and collect their results and to better adapt "counselling", their usefulness to detect of hepatitis B virus has not been evaluated to date. The main objective of the Optiscreen B Study is to determine the benefit, if any, of using rapid tests as a screening tool to improve diagnosis, care and prevention of hepatitis B. Individuals risk of HBV-infection will be randomized into 2 groups, one group for which screening will be performed by usual serological test and a second group for which screening will be based on rapid tests. Centers will be selected to represent a diverse range of health centers whose aims include screening, prevention and/or vaccination.

NCT ID: NCT01760122 Completed - Chronic Hepatitis B Clinical Trials

Efficacy and Safety of Peginterferon Alfa-2b in HBeAg Positive Chronic Hepatitis B

Start date: March 2013
Phase: Phase 3
Study type: Interventional

This study is aimed to assess the efficacy and safety of Peginterferon alfa-2b (40kD, Y-shape), in a dose of 180μg/week, in chronic hepatitis B patients, and collects sufficient evidences for the listed of the studied drug.

NCT ID: NCT01745822 Completed - Pregnancy Clinical Trials

Maternal Antiviral Prophylaxis to Prevent Perinatal Transmission of Hepatitis B Virus in Thailand

iTAP
Start date: January 2013
Phase: Phase 3
Study type: Interventional

Chronic hepatitis B (CHB) infection is complicated by cirrhosis and liver cancer. In Thailand, 7% of adults are chronically infected by Hepatitis B virus (HBV). The risk of perinatal transmission of HBV is about 12% when a mother has a high HBV load in her plasma, even if her infant receive specific immunoglobulin and vaccine. The hypothesis of this study is that a potent antiviral, tenofovir, can decrease HBV load in HBV infected pregnant women and therefore reduce the risk of perinatal transmission/ Pregnant women participating in this study will receive tenofovir or placebo during the last trimester of pregnancy and two months postpartum. The risk of perinatal transmission will be compared between the two groups. The results of the study will help define policy to manage HBV infected pregnant women to prevent perinatal transmission.

NCT ID: NCT01743079 Completed - Chronic Hepatitis B Clinical Trials

Study of Telbivudine and Lamivudine to Prevent Vertical Transmission of Hepatitis B

Start date: January 2009
Phase: Phase 4
Study type: Interventional

The purpose of this study is to evaluate the efficacy and safety of telbivudine and lamivudine use during late pregnancy for the prevention of HBV perinatal transmission in highly viraemic mothers.
