Active clinical trials for "Hepatitis B"

The purpose of this study is to evaluate the immunogenicity and reactogenicity of various formulations of recombinant hepatitis B vaccine with different adjuvants in healthy adult volunteers following the 0, 1, 6 months schedule

In this study the safety and immunogenicity of 2 different formulations of the candidate HBV-MPL vaccine administered according to a 0, 6-month schedule were explored and compared to that of Engerix™-B in healthy adolescents aged 11 to 15

This study is undertaken to assess the immune response and safety profile of 4 lots of the novel adjuvanted hepatitis B vaccine that were formulated following different processes, with Engerix™-B as the control vaccine

This study examines the effect of telbivudine compared to lamivudine on the early viral kinetics in patients with chronic hepatitis B. The virus Kinetics is measured by the viral load (HBV-DNA) reduction in the serum during the first 12 weeks of therapy.

Subjects who had not responded to previous hepatitis B vaccination were vaccinated with either the adjuvanted HBV-MPL vaccine or Engerix™-B vaccine according to a three-dose vaccination schedule (0, 1, 2 months) and boosted at Month 12 as per their group allocation. The immunogenicity and safety of the HBV-MPL vaccine were compared with the control vaccine, Engerix™-B.

The purpose of this study is to investigate the efficacy of telbivudine in Blacks/African Americans and Hispanics/Latinos with compensated chronic hepatitis B during 52 weeks of treatment

The objective is to assess the efficacy of Hepatitis B Virus vaccination in a population of IBD patients treated with immunosuppressive medications.

An interventional study will be performed in subjects aged 1-65 years old to evaluate effects of different doses of hepatitis B vaccines in low or non-response population.

This study was conducted in healthy infants and will provide new immunogenicity and safety data for the modified process hepatitis B vaccine. This study was conducted to address the following: to evaluate the immunogenicity and safety data of the 5 microgram dose of the modified process hepatitis B vaccine compared with a 10 microgram dose of the modified process hepatitis B vaccine, to evaluate another dosing schedule of 2, 4, and 6 months, and to provide descriptive immunogenicity data of another marketed vaccine (ENGERIX-B®).

To assess the safety and immunogenicity of a booster dose of hepatitis B vaccine in children who have received a 3-dose primary series of either RECOMBIVAX HB or ENGERIX-B. The primary vaccination series (was given 4 to 8 years prior to study entry and consisted of a licensed hepatitis B vaccine product (either RECOMBIVAX HB or ENGERIX-B). The booster dose given in this study will be either an investigational Merck product (Modified Process Hepatitis B Vaccine) or licensed ENGERIX-B vaccine.
