Active clinical trials for "Hepatitis B"

The aim of this clinical trial is to evaluate the efficacy, safety, and tolerability of Niuliva (Hepatitis B virus immune globulin) in the prophylaxis of hepatitis B virus (HBV) reinfection in patients submitted to liver transplantation due to HBV-induced liver disease by reaching and maintaining certain hepatitis B antibody (HBsAg) levels considered as protective during the first six and twelve months post-transplantation.

The goal of this study is to evaluate two sets of interventions to increase acceptance of hepatitis B virus (HBV) vaccination in patients attending sexually transmitted disease (STD) clinics. The 1st set of interventions, with 3 levels, is based on message framing. The 3 levels are: 1. information only; 2. gain-framed message; and 3. loss-framed message. The 2nd set of interventions, with 2 levels, involves how the vaccine is recommended by the health care provider. The 2 levels are: 1. HBV vaccine offered; and 2. HBV vaccine recommended. The outcome of interest is1st dose acceptance.

Confirm the safety of maraviroc when used as a component of combination antiretroviral therapy in HIV and Hepatitis co-infected patients.

Aims: This prospective trial seeks to investigate the efficacy of a financial incentive in increasing the uptake and completion of the HBV vaccine series among people who inject drugs (PWID). Using a randomised controlled trial design, the investigators will offer the 3 dose, accelerated HBV schedule to eligible PWID allocated to either a standard of care or incentive condition. Participants allocated to the incentive condition will receive a small incentive payment after the second and third dose of the vaccine. It is hypothesized that the proportion of participants who complete the vaccine series in the incentive payment arm will be higher compared to the non-incentive payment arm (standard of care).

The purpose of this booster study is to evaluate, in subjects primed in the primary study 106786, the persistence, at the time of the booster vaccination, of antibodies elicited by the different formulation of DTPa-HBV-IPV/ Hib vaccine (Infanrix Hexa TM). The study will also evaluate the immune response of these subjects to a DTPa-HBV-IPV/Hib booster. This protocol posting deals with the objectives and outcome measures of the booster phase. The objectives and outcomes measures of the primary phase are presented in a separate protocol posting (NCT = 00376779).

The purpose of the study is to compare the safety, reactogenicity and immunogenicity of different formulations of adjuvanted recombinant hepatitis B vaccine to that of Engerix™-B when administered at 0, 2 months with a booster at month 12 if necessary

This study will evaluate the immunogenicity and safety of different formulations of the candidate HBV-MPL vaccine administered according to a 2-dose schedule and compare it to that of Engerix™-B administered according to a 3-dose schedule in order to determine the optimal dose of each component of the candidate HBV-MPL vaccine when administered at 0 and 6 months

This trial is designed to evaluate the immunogenicity, reactogenicity and safety of an MPL-adjuvanted recombinant hepatitis B vaccine in comparison with those of Engerix™-B in haemodialysis patients with or without previous vaccination against hepatitis B

The objective of this study is to compare the Safety and Immunogenicity of a mixed sequence of 2 different pentavalent vaccines (Diphtheria-Tetanus- Pertussis, Hepatitis B and Hib combination Vaccines) with single sequence of Shan 5 in infants.

The purpose of this study is to find out if taking a combination of telbivudine and adefovir or tenofovir and telbivudine can lower the amount of Hepatitis B virus in patients that have been taking adefovir alone for at least 5 months and have had less than optimal responses. The safety of taking telbivudine and adefovir together or tenofovir and telbivudine together will also be studied.
