Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The proportion subjects with HBsAg ≤ 20,000 IU/mL at 12 week treatment of PEG-IFN in HBeAg-positive Chronic Hepatitis B | 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 | 12 week from baseline |
Secondary
| Measure | Time frame |
|---|---|
| The change of HBV DNA at Week 12 from baseline | 12 week from baseline |
| The change of HBsAg at Week 4, 8, 12 from baseline | 4, 8, 12 week from baseline |
| The change of ALT at week 4, 8, 12 from baseline | 4, 8, 12 week from baseline |
| The proportion of HBV DNA undetectable level (< 60 IU/mL, approximately 300 copies/mL) at week 12 | 12 week from baseline |
