Further study details as provided by GlaxoSmithKline:

Primary Outcome Measures:
  • Number of Participants With Anti-hepatitis B Surface Antigen (HBs) Antibody Concentrations Above the Cut-off Value [ Time Frame: One month after the challenge dose of HBV vaccine ] [ Designated as safety issue: No ]
    Anti-HBs antibody cut-off value assessed was 100 milli-international unit per milliliter (mIU/mL)

Secondary Outcome Measures:
  • Number of Participants With Anti-HBs Antibody Concentrations Above the Cut-off Value [ Time Frame: Before challenge dose of HBV vaccine ] [ Designated as safety issue: No ]
    Anti-HBs antibody cut-off values assessed include 3.3, 10 and 100 mIU/mL

  • Number of Participants Reporting Solicited Local Symptoms [ Time Frame: During the 4-day follow-up period after the challenge dose of HBV vaccine. ] [ Designated as safety issue: No ]
    Solicited local symptoms assessed include pain, redness and swelling

  • Number of Participants Reporting Solicited General Symptoms [ Time Frame: During the 4-day follow-up period after the challenge dose of HBV vaccine. ] [ Designated as safety issue: No ]
    Solicited general symptoms assessed include fatigue, fever, gastrointestinal symptoms, and headache

  • Number of Participants Reporting Unsolicited Adverse Events [ Time Frame: During the 31-day follow-up period after the challenge dose of HBV vaccine. ] [ Designated as safety issue: No ]
    An Adverse Event is any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

  • Number of Participants Reporting Serious Adverse Events (SAE) [ Time Frame: After the challenge dose of HBV vaccine. ] [ Designated as safety issue: No ]

    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.
