Filter by:The purpose of this study is to compare PEG-interferon alfa-2b and two different doses of rivavirin for the treatment of chronic hepatitis C in previously untreated adult subjects
There is evidence on the beneficial effects of the administration of angiotensin II type 1 (AT1) receptors antagonists on liver fibrosis in hepatic stellate cells, experimental models of liver fibrosis in rodents and limited information in chronic hepatitis C with mild fibrosis. The purpose of this study is to investigate the effect of long-term administration of oral Losartan, an AT1 receptor antagonist, on liver fibrogenesis in patients with chronic hepatitis C and fibrosis F2-F3 (METAVIR score).
This study was designed to evaluate and compare the safety and tolerability of tenofovir disoproxil fumarate (TDF), emtricitabine (FTC)/TDF, and entecavir (ETV) in the treatment of hepatitis B patients with decompensated liver disease. Safety was assessed by evaluating adverse events (AEs) and laboratory abnormalities. Efficacy was assessed by evaluating reductions in Child-Pugh-Turcotte (CPT) and Model for End Stage Liver Disease (MELD) scores, reductions in hepatitis B virus (HBV) deoxyribonucleic acid (DNA), changes in liver enzymes, development of drug-resistant mutations, and generation of antibody to virus. A maximum randomized treatment duration of 168 weeks was planned. Since subjects with decompensated liver disease were enrolled into this study, it was necessary to provide early intervention strategies if profound viral suppression was not expeditiously achieved. For this reason, subjects with a decrease in plasma HBV DNA from baseline of < 2 log_10 copies/mL and plasma HBV DNA > 10,000 copies/mL (or plasma HBV DNA > 1,000 copies/mL for subjects who entered the study with HBV DNA < 10,000 copies/mL) at Week 8 had the option to start open-label FTC/TDF and continue in the study. Subjects with a virologic breakthrough or who had plasma HBV DNA levels remaining > 400 copies/mL (confirmed) at or after 24 weeks of treatment could have been unblinded at the investigator's discretion for selection of alternative anti-HBV therapy that may have included open-label FTC/TDF. If study drug was permanently discontinued, immediate initiation of another anti-HBV regimen was strongly recommended.
This is an extension study of HCV-05-002. The objective of this study is to evaluate the safety and efficacy of celgosivir plus peginterferon alfa-2b, with or without ribavirin, for an additional 36 weeks in patients with chronic hepatitis C genotype 1 infection.
The immune response of uraemic patients to hepatitis B vaccination is impaired compared to healthy subjects. After vaccination, anti-HBs peak antibody concentrations are reduced. As the persistence of anti-HBs is closely related to the initial anti-HBs peak, a more immunogenic vaccine, allowing higher antibody concentrations, would be a benefit for this population.
Hepatitis B prevention in non-responders uraemic patients is currently based on both HBsAg surveillance and the isolation from HBsAg carriers. A more immunogenic vaccine would be a benefit for this population.
The pre-dialysis, peritoneal dialysis and haemodialysis patients would benefit from an improved hepatitis B vaccine, which will elicit stronger and faster cellular and humoral immune responses after the primary vaccination course.
The aim of this study is to evaluate the persistence of hepatitis A antibodies at 138, 150, 162, 174,186, 198, 210, 222, 234 and 246 months after subjects received their first dose of a 2 dose vaccination schedule of hepatitis A vaccine. This protocol posting deals with objectives & outcome measures of the extension phase at year 11 to 20. No additional subjects will be recruited during this long-term follow-up.
The purpose of this study is to determine the optimal treatment duration of antiviral therapy for chronic hepatitis B.
The purpose of this study is to compare the immune response, safety and reactogenicity of Tritanrix™-HepB/Hib-MenAC vaccine given either with or without a birth dose of hepatitis B vaccine to Tritanrix™-HepB/Hiberix™ when given to healthy infants (born to mothers who do not carry hepatitis B virus) at 6, 10 & 14 weeks of age. This study will also include a small group of infants born to mothers who do carry hepatitis B virus; these infants will receive a birth dose of hepatitis B vaccine and will be vaccinated with Tritanrix™ HepB/Hib-MenAC at 6, 10 & 14 weeks age.
