Active clinical trials for "Hepatitis B"

DTaP-HB-PRP~T combined vaccine is being developed in order to comply with expanding programs for immunization in infancy, while offering the benefit of a reduced number of injections, and potentially of an increased acceptance. Primary Objectives: To describe the antibody persistence at 12 to 18 months following a three-dose primary series vaccination of either DTaP-HB-PRP~T or Tritanrix-Hep B/Hib™ given at 6, 10 and 14 weeks of age, and one dose of Hepatitis B (Hep B) vaccine given at birth. To describe the effect of a booster dose of DTaP-HB-PRP~T on immunogenicity at 12 to 18 months following a three-dose primary series vaccination of either DTaP-HB-PRP~T or Tritanrix HepB/Hib™ given at 6, 10 and 14 weeks of age, and one dose of Hep B vaccine given at birth. Secondary Objective: To describe the safety profile of the booster dose of the DTaP-HB-PRP~T vaccine when administered concomitantly with Oral Polio Vaccine (OPV).

The purpose of this study is to further evaluate the safety and seroprotective immune response of a new investigational hepatitis B virus (HBV) vaccine, HEPLISAV™, in subjects 11-55 years old. The primary hypothesis is that HEPLISAV™ is well tolerated.

This study was done to evaluate the effect of various adjuvants in combination with HBsAg as a model antigen on the induction of immune responses, mainly cytotoxic T lymphocytes (CTL) in healthy volunteers. The study was also done to evaluate the safety and reactogenicity of the various adjuvanted vaccines.

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.

Patients with chronic hepatitis B constantly produce the virus in the body. The disease of chronic hepatitis B is the body responding to the virus. Use of steroids can adjust this response. After taking steroids, viral production usually increases and liver function tests increase. After stopping steroids, viral production usually decreases. Many studies in the past have studied taking a low dose steroid before treating hepatitis B. Those studies have shown that low dose steroids help your body to clear the virus. The goal of this study is to improve the liver function by slowing viral growth.

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

The purpose of the study is to assess the pharmacokinetics, safety and efficacy of HepaGam B in combination with antiviral therapy for the prevention of hepatitis B virus (HBV) recurrence following HBV-related orthotopic liver transplant.
