Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Hepatitis B Hepatitis A Biological: Twinrix™ Adult Biological: Twinrix™ Junior Phase 3

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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 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).

  2. 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.

  3. 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.
