|
| 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 |

|
| E.2.2 | Secondary objectives of the trial |
To describe the immunogenicity of HB-AS02V and HBVAXPRO® in terms anti-HBs seropositivity rate (defined as percentage of subjects with anti-HBs antibody concentrations above or equal to 3.3 mIU/ml), seroprotection rate (defined as percentage of subjects with anti-HBs antibody concentrations above or equal to 10 mIU/ml) and percentage of subjects with anti-HBs antibody concentrations above or equal to 100 mIU/ml, at Month 1.
To evaluate the safety and reactogenicity of the HB-AS02V vaccine and of HBVAXPRO® after one injection.

| E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
| E.3 | Principal inclusion criteria |
A male or female subject ³above or equal to 15 years of age at the time of the study entry.
Pre-dialysis patients, peritoneal dialysis patients and patients on haemodialysis. Pre-dialysis patients is defined as a subject with a documented creatinine clearance of less than or equal to 30 ml/min (as estimated by the Cockroft-Gault formula).
Seronegative for anti-HBc antibodies and for HBsAg at screening.

Documented response to previous hepatitis B vaccination (anti-HBs ³ 10 mIU/ml after one full course of four injections of licensed vaccine, without subsequent boosters) but for whom there is a documented loss of anti-HBs antibody concentrations below 10 mIU/ml.

Use of any investigational or non-registered drug or vaccine within 30 days preceding the study vaccine administration, or planned use during the study period.
Use of any registered vaccine within 7 days preceding the study vaccine administration.
History of hepatitis B infection or known exposure to hepatitis B virus within six months.
Use of immunoglobulins within six months preceding the first study vaccination.
Immunosuppression caused by the administration of parenteral steroids or chemotherapy (oral steroids are allowed).
Any confirmed or suspected human immunodeficiency virus (HIV) infection.
A family history of congenital or hereditary immunodeficiency.
History of allergic disease or reactions likely to be exacerbated by any component of the vaccines.
Pregnant or lactating female
