Active clinical trials for "Hepatitis A"

To evaluate the persistence of immune response 5 years and 6 years after the first vaccine dose.

To evaluate the immunogenicity, reactogenicity and safety of Hepatyrix when compared to the concomitant administration of Typherix and Havrix, and when compared to the administration of monovalent vaccines, Havrix or Typhim Vi. Furthermore, the study will evaluate the persistence of anti-Vi and anti-HAV antibodies up to 36 months after administration of the first dose of the study vaccine.

This study is to assess the safety and immunogenicity of three consecutive lots of JE-CV in toddlers aged 12-18 months. Primary objective: To demonstrate the bio-equivalence of three lots of JE-CV vaccine manufactured by sanofi pasteur. Secondary objective: To describe the safety of vaccination in all subjects

To evaluate the response to an additional dose (challenge dose) of hepatitis B vaccine, when given to subjects who had received primary vaccination of Engerix™-B vaccine approximately 72-78 months ago. This protocol posting deals with objectives & outcome measures of the challenge phase. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Hepatitis C virus infection is the most common blood-borne infection in the United States and is a leading cause of chronic liver disease affecting 130 million people around the world. It is estimated that 1.6% of the US population may be affected by Hepatitis C infection. The only recommended treatment that has been approved for your condition is the use of interferon and ribavirin. In patients with chronic Hepatitis C, there tends to be an accumulation of fat in the liver. Fatty liver has been associated with failure of treatment. The accumulation of fat in the liver has been blamed on a particular type of fat called triglycerides. Fish oil, by reducing a type of fat called VLDL, can lower the triglyceride concentration by as much as 50 percent or more. This study seeks to determine if the administration of fish oil along with standard treatment to patients with Hepatitis C will increase the treatment response rates.

The purpose of this study is to evaluate the safety, immunogenicity and reactogenicity of MPL-adjuvanted recombinant hepatitis B vaccine in comparison with those of Engerix™-B in healthy adult volunteers following two different schedules: 0, 2 months and 0, 6 months

This study compares the immunogenicity and safety of the novel adjuvanted HBV vaccine and Engerix™-B administered to subjects who were positively identified as having the HLA-DQ2 genotype

This study seeks to evaluate the safety and efficacy of taking fluvastatin along with peginterferon alfa in previous partial responders with genotype 1 HCV.

The current study will evaluate immunological memory to hepatitis B antigen in subjects who received primary neonatal vaccination of hepatitis B vaccine (Engerix™-B ), 20 years ago in the primary study and who have anti-HBs antibody concentrations < pre-defined cut-off values at the previous long-term time point. All participating subjects will receive a challenge dose of hepatitis B vaccine. Subjects will be aged approximately 20-21 years at the time of this study. No new subjects will be recruited in this long-term follow-up study. Blood sampling will be done one month after the administration of the challenge dose. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

This study will only include infants born to mothers who are tested as seronegative for human immunodeficiency virus (HIV) & hepatitis B surface antigen (HBsAg). The purpose of this study is to demonstrate in infants who received a birth dose of hepatitis B vaccine that Tritanrix™-HepB/Hib-MenAC vaccine is at least as good as Tritanrix™-HepB/Hiberix™ with respect to immunogenicity of the hepatitis B antigen.
