GlaxoSmithKline
  Purpose
To evaluate the persistence of anti-hepatitis A virus (anti-HAV) and anti-hepatitis B surface antigen (anti-HBs) antibodies up to 6, 7, 8, 9 and 10 years after administration of the first dose of the study vaccine.

Official Title: Evaluate Persistence of Immune Response of GSK Biologicals' TWINRIX™ Vaccine Administered According to 0,6 Month Schedule Versus TWINRIX™ JUNIOR Administered According to 0,1,6 Month Schedule, in Subjects Aged 12-15 Years at Time of First Vaccine Dose

Primary Outcome Measures:
  • Number of Subjects With Anti-hepatitis A Virus (HAV) Antibody Concentrations Above the Cut-off Value [ Time Frame: Year 6, 7, 8, 9 and 10 after the first vaccine dose of a two-dose or three-dose primary vaccination ]
    Anti-HAV antibody concentration cut-off value assessed was ≥ 15 milli-International Units per milliliter (mIU/mL).

  • Number of Subjects With Anti-Hepatitis B Surface Antigen (HBs) Antibody Concentrations Above the Cut-Off Value [ Time Frame: Year 6, 7, 8, 9 and 10 after the first vaccine dose of a two-dose or three-dose primary vaccination ]
    Anti-HBs antibody concentration cut-off value assessed was ≥ 3.3 mIU/mL.

  • Serious Adverse Events (SAE) Causally Related to Primary Vaccination or Related to Hepatitis A or B Infection or Related to Study Participation (Blood Sampling) [ Time Frame: From Year 6 through to Year 10 ]

    An SAE is any untoward medical occurrence that:

    results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/ incapacity, is a congenital anomaly/birth defect in the offspring of a study subject, or may evolve into one of the outcomes listed above.

Arms Assigned Interventions
Active Comparator: Group Twinrix Adult
Subjects received Twinrix™ Adult (720/20) in a 0, 6 month schedule in the primary study.
Biological: Twinrix™ Adult
Intramuscular administration in the deltoid region (2 doses).
Active Comparator: Group Twinrix Junior
Subjects received Twinrix™ Junior (360/10) in a 0, 1, 6 month schedule in the primary study.
Biological: Twinrix™ Junior
Intramuscular administration in the deltoid region (3 doses).

Detailed Description:

Open, randomized, long-term antibody persistence studies. Immune persistence was compared between subjects who received one of the two formulations of GlaxoSmithKline Biologicals' combined hepatitis A and hepatitis B vaccine according to a two-dose or three-dose schedule. These long-term follow-up studies involved taking blood samples at approximately 6, 7, 8, 9 and 10 years after the primary vaccination of combined hepatitis A and B vaccine, to assess antibody persistence and a retrospective safety follow-up.

The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
