Active clinical trials for "Hepatitis A"

Hepatitis A vaccine will be given either alone or together with measles, mumps, rubella, and varicella vaccine and pneumococcal 7-valent conjugate vaccine at the first dose and together with measles, mumps, rubella, and varicella [Oka/Merck] virus vaccine at the second dose. Immunogenicity and safety data will be collected after each dose of vaccine.

This is an exploratory study to evaluate the impact of eliminating steroid administration upon viral HCV load at 12 months measured by quantitative serum HCV-RNA determination in patients transplanted for HCV cirrhosis.

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.

Objective: Determine if maximum doses of rosuvastatin are safe in patients infected with hepatitis C and if the so called pleiotropic effects of rosuvastatin cause a decrease in the HCV viral load. Primary study parameters: 1. to which extend causes rosuvastatin serious side effects like rhabdomyolysis and hepatotoxicity in patients chronically infected with hepatitis C? 2. does treatment with rosuvastatin in HCV infected patients lead to lower HCV-RNA viral load? 3. Is a decrease in LDL correlated to a decrease in HCV-RNA load?

To evaluate the persistence of antibodies against hepatitis B at 30, 42, 54 and 66 months after the first dose of the hepatitis B primary vaccination course. Subjects were aged 11 to 15 years at the time of the primary vaccination course. At the time of enrollment in the present long-term follow-up study subjects were aged 13 to 18 years. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Persistence of anti-HBs antibodies at Month 24, 30 and 36 in subjects who had completed primary vaccination was evaluated. The anamnestic response to a booster dose was evaluated in subjects with anti-HBs antibody titres < 10 mIU/ml at previous timepoint. The study also evaluated the effect of a booster dose of the vaccine (Month 42) after primary vaccination.

Hepatitis B is a contagious virus that can damage a person's liver. It can be prevented by vaccination, but for many HIV-positive people, the vaccines do not help them achieve adequate protection against this virus. In an attempt to improve response to vaccination and achieve protection from hepatitis B, this trial will compare the immune system response to 3 hepatitis B vaccine regimens in HIV-positive adolescents 12 through 24 years of age.

The purpose of the study is to evaluate the immunogenicity, safety and reactogenicity of a booster dose of DTPw-HBV/Hib-MenAC compared to DTPw-HBV/Hib given to healthy subjects at 15 to 24 months of age primed with 3 doses of Tritanrix-HepB/Hib-MenAC in study 100480. Antibody persistence will be evaluated at 24 to 30 months. Immunogenicity, safety and reactogenicity of a dose of Mencevax ACWY given at 24 to 30 months will also be evaluated when given to subjects not boosted with a MenA conjugate and/or MenC containing vaccine.

This trial is an experimental, randomized, double blind, prospective intervention study Approximately 100 subjects will be enrolled in this trial, divided into 2 arms, as follow: For adult (18-40 years old)

This is a preliminary trial of a Hepatitis B vaccine (Heplisav-B) in medically immunosuppressed patients. The purpose of this study is to test the ability of Heplisav-B to produce high levels of antibody that neutralize the virus and prevent hepatitis B from coming back. Another important purpose is to test the safety of this vaccine in patients taking immune suppressive medicines.
