Phase 2
Completed
- Conditions
- Hepatitis B
- Interventions
- Biological: HBV-MPL vaccineBiological: Engerix™-B
- Registration Number
- NCT00698906

- Brief Summary
This study will evaluate the immunogenicity and safety of different formulations of the HBV-MPL vaccine administered according to a 2-dose schedule and compare it to that of Engerix™-B administered according to a 3-dose schedule in order to determine the optimal dose of each component of the candidate HBV-MPL vaccine when administered at 0 and 6 months
- Detailed Description
At the time of conduct of this study, the sponsor GlaxoSmithKline was known by its former name SmithKline Beecham
