Primary Outcome Measures:
  • Immunogenicity: HBV specific T-cell response by ELISPOT [ Time Frame: Change from Baseline in HBV specificic T-cell response at 16 weeks ]
    sample for immunologic assay will be collected at each visit; VS(~4week), VT1(0week), VT2(8week), VF(16week. T-cell response will be measured by ex-vivo & cultured ELISPOT.


Secondary Outcome Measures:
  • HBsAg titer [ Time Frame: Change from baseline in HBsAg titer at 16 weeks ]
    sample for HBsAg will be collected at each visit; VS(~4week), VT1(0week), VT2(8week), VF(16week. Change from baseline in HBsAg titer will be measured at VF.


Enrollment: 6

Study Completion Date: July 2013
Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
HBsAg vaccine with Entecavir Drug: HBsAg vaccine with Entecavir
