A Research Study to Test Safety, Tolerability, and Immunogenicity of a Recombinant Hepatitis B Vaccine Manufactured With an Upgrade to the Production Process (V232-054)

Phase 3
Completed
Conditions
Hepatitis B Infection
Interventions
Biological: V232 Current Process Hepatitis B Vaccine
Registration Number
NCT00489099
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

A study to evaluate the safety, tolerability, and immunogenicity of a recombinant hepatitis B vaccine manufactured using an upgrade to the production process. The primary hypotheses tested at 1 month after the third dose of vaccine are the following: 1) the 3 lots of the process upgrade vaccine induce similar seroprotection rates to hepatitis B surface antigen (HBsAg), 2) the combined lots of the process upgrade vaccine induce adequate seroprotection to HBsAg, and 3) the process upgrade vaccine will induce geometric mean antibody titers to HBsAg that are non-inferior or superior to those induced by the current process vaccine.
