Active clinical trials for "Hepatitis B"

In HIV infected patients, individuals exposed to the virus of Hepatitis B are more susceptible to develop a chronic and severe liver disease with a major risk of cirrhosis and liver cancer. However, the existing protocol of vaccination against Hepatitis B is less efficient in HIV-infected patients than in non HIV-infected-patients, and, in case of response, its longevity has to be followed up carefully. This study compares the efficacy of the standard protocol vaccination with GenHevac-B and 2 other protocols, a double-dose of GenHevac-B and a set of intradermal injections of Genhevac-B, in HIV-infected patients with lymphocytes T CD4 level above 200 permm3.

This study will evaluate the safety and immunogenicity of GSK Biologicals' GSK2202083 vaccine co-administered with Prevenar 13® at 2, 4 and 12 months of age and with Rotarix™ at 2 and 4 months of age.

This study will evaluate the persistence of the immune response to HAV (hepatitis A virus) antigens and HBs (hepatitis B surface) antigens in healthy adults previously vaccinated with Twinrix Adult in the primary study, HAB-032 (208127/022). The subjects will be invited for blood sampling 16, 17, 18, 19 and 20 years after the primary vaccination to evaluate the antibody persistence. For subjects in whom low circulating antibodies are detected, the presence of immune memory against hepatitis A & B antigens will be investigated by the administration of a challenge dose of the appropriate vaccine (Havrix and/or Engerix-B) at the next planned visit. No new subjects will be recruited during this study.

The purpose of this study is to evaluate the immune response and reactogenicity of GSK Biologicals' DTPa-HBV-IPV combined pentavalent vaccine and Hib tetanus conjugate vaccine, administered concomitantly as a three-dose primary vaccination course.

A phase 3, multicenter, open label study to assess the safety and efficacy of Nabi-HB, administered subcutaneously in patients with Hepatitis B Virus Associated Liver Disease who underwent liver transplantation.

This is a follow-up of Study A3L11 (NCT00404651). Immunogenicity To describe the antibody persistence following a primary series vaccination of either DTaP-IPV-Hep B-PRP~T or Infanrix hexa™. To describe the immunogenicity of a booster dose of DTaP-IPV-HepB-PRP~T in a subset of subjects. Safety - To describe the safety profile after a booster dose of DTacP-IPV-HepB-PRP~T.

Only subjects who participated in the primary study will be invited to participate in the extension phase and the challenge dose phase of this study.

This study was conducted to evaluate the lot-to-lot consistency of three lots of HBV-MPL vaccine and to compare their safety and immunogenicity with that of Engerix™-B.

The purpose of this study is to enroll pre-liver transplant patients who will be vaccinated with either the novel adjuvanted HBV vaccine or double doses of Engerix™-B. The immunogenicity and safety of the novel adjuvanted vaccine will be compared to Engerix™-B as the control vaccine

The purpose of the present trial is to evaluate 6 vaccine formulations of recombinant hepatitis B vaccine for their reactogenicity and immunogenicity when administered at 0-2 months with a booster at month 12
