Comparison of adjuvanted hepatitis B vaccine to double dose of Engerix™-B in pre- /haemodialysis patients aged ≥15 years
International studies have repeatedly documented a substantial prevalence of sexual risk behaviors and high rates of human immunodeficiency virus (HIV) and other sexually transmitted infections (STI) ranging from 5%-56% amongst long-distance truck drivers ("truckers") living in diverse international settings including India, Bangladesh, South Africa, China, Laos and Thailand. The prevalence of sexual risk factors and STI/HIV in US drivers is unknown. This proposal will provide both qualitative and quantitative data on HIV risk behaviors by interviewing and testing truckers working for established long-distance trucking firms, the sector which accounts for most of the jobs in the trucking and warehousing industry in the United States. The data obtained from this study will be used to inform the development of an HIV prevention intervention for long-haul truck drivers.
Since a proportion of patients with Acute Viral Hepatitis-B develop severe hepatitis and fulminant hepatic failure, it is logical to believe that a rapid reduction in the HBV DNA levels by using antiviral agents could result in a less intense host response against the hepatitis B virus. However, the experience with lamivudine treatment of immunocompetent patients with AVH-B is limited.The aim of the present study was to evaluate the efficacy, utility and safety of lamivudine in treating immunocompetent patients with AVH-B.
The purpose of this study is to show that the immunogenicity of newly formulated DTPa-HBV-IPV/Hib vaccine is as good as the immunogenicity of the currently licensed formulation of the vaccine. The vaccine will be administered as a primary vaccination course to healthy infants at 2, 3 and 4 months of age and its safety and reactogenicity will also be assessed.
This is an open label, randomized, comparative, multi-center study. Subjects will be screened within 2 weeks prior to study entry to establish eligibility. Subjects who meet all the selection criteria will be randomly assigned 1:1 to (1) once-a-week, subcutaneous Pegylated interferon alfa-2b (PegIntron) (1.5 mcg/kg body weight) or (2) oral adefovir 10 mg daily. The treatment phase will be 24 weeks for PegIntron and 48 weeks for adefovir. All subjects completing the assigned treatment phase will be followed up for an additional 48 weeks for PegIntron and 24 weeks for adefovir as observation phase. The primary objective is to establish the efficacy profile of PegIntron. Secondary objectives are to compare the efficacy profile of PegIntron with that of adefovir, compare efficacy of PegIntron in lamivudine-naïve and lamivudine-experienced subjects, and to establish the safety profile of PegIntron in treating patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B.
The purpose of this clinical research study is to develop observational clinical experience with the use of entecavir in participants who are either of Black/African-American race or of Hispanic ethnicity.
This study assessed the immunogenicity and safety of two vaccination regimens that employed either GSK Biologicals' combined DTPa-HBV-IPV/Hib vaccine or DTPa-IPV/Hib vaccine. In the two groups, infants received the DTPa-IPV/Hib vaccine at 3 and 4 months of age, as the first 2 doses of the primary vaccination course. At 5 months of age, they received either the DTPa-IPV/Hib vaccine co-administered with the HBV vaccine or a dose of the DTPa-HBV-IPV/Hib vaccine as a 3rd dose. Infants in the two groups had previously received 2 doses of HBV vaccine at birth and at 1 month of age.
The purpose of this trial is to determine the safety, tolerability and effectiveness of KRN7000 for chronic hepatitis B infection.
The purpose of this study is to evaluate the durability of antiviral activity in chronic hepatitis B patients who showed complete response in L-FMAU-301,L-FMAU-302 or L-FMAU-303 trial.
