| MedDRA Classification |
| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To demonstrate the superiority of HB-AS02V vaccine compared to Fendrix® vaccine in terms of anti-HBs seroprotection rates (percentage of subjects with anti-HBs antibody concentrations above or equal to 10 mIU/ml) at Month 2. |
|
| E.2.2 | Secondary objectives of the trial |
To explore the superiority of HB-AS02V vaccine (at Month 2) compared to Fendrix® vaccine (at Month 3) in terms of anti-HBs seroprotection rates and in terms of anti-HBs geometric mean concentrations (GMC).
To explore the superiority of HB-AS02V compared to Fendrix® vaccine in terms of anti-HBs seroprotection rates at Months 1, 3, 6 and 7 and in terms of anti-HBs GMC achieved.
To describe the immunogenicity of HB-AS02V and Fendrix® vaccines in terms of anti-HBs seropositivity rate, seroprotection rates, the percentage of subjects with anti-HBs antibody concentrations above or equal to 100 mIU/ml and GMCs at Months 1, 2, 3, 6 and 7.
To evaluate the quality of the immune response elicited one month after a full course of primary vaccination in a subset of subjects using a competitive RF1 ELISA.
To evaluate the safety and reactogenicity of the HB-AS02V vaccine and of Fendrix® vaccine after each dose and per subject. |
