Further study details as provided by Yonsei University:

Primary Outcome Measures:
  • The proportion subjects with HBsAg ≤ 20,000 IU/mL at 12 week treatment of PEG-IFN in HBeAg-positive Chronic Hepatitis B [ Time Frame: 12 week from baseline ]
  • The proportion subjects with any decline of HBsAg and/or HBV DNA decline more than 2 log copies/ml at 12 week treatment of PEG-IFN in HBeAg-negative CHB [ Time Frame: 12 week from baseline ]

Secondary Outcome Measures:
  • The change of HBV DNA at Week 12 from baseline [ Time Frame: 12 week from baseline ]
  • The change of HBsAg at Week 4, 8, 12 from baseline [ Time Frame: 4, 8, 12 week from baseline ]
  • The change of ALT at week 4, 8, 12 from baseline [ Time Frame: 4, 8, 12 week from baseline ]
  • The proportion of HBV DNA undetectable level (< 60 IU/mL, approximately 300 copies/mL) at week 12 [ Time Frame: 12 week from baseline ]
