Primary Outcome Measures:
  • Sustained virological response after stopping anti-viral treatment [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    The proportion of patients with sustained virological response after stopping anti-viral treatment


Biospecimen Retention:   Samples Without DNA

Initially, 30ml of heparinized peripheral blood will be obtained from each subjects. After then, 10ml of heparinized peripheral blood will be additionaly obtained at every 3 months follow-up visit.


Estimated Enrollment: 100
Study Start Date: February 2012
Estimated Study Completion Date: March 2016
Estimated Primary Completion Date: March 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts
Chronic hepatitis B

Detailed Description:

In the recommendation by the Asian PAcific Association for the Study of the Liver(APASL), antiviral drug is recommended to stop when HBeAg seroconversion has developed for more than 6 months among HBeAg-positive patietns. For HBeAg-negative patients, the APASL consensus recommended stopping anti-viral treatment when HBV DNA remained undetectable for three separates occasion 6 months apart. Nontheless, approximately 25% to 50% of the patients still develop hepatitis relapse after stopping anti-viral therapy even if these recommendations are followed. In this study, the investigators aimed to investigated the off-treatment sustained response in chronic hepatitis B parients following the stopping anti-viral treatment guideline in Korea.
