简要总结
The purpose is to evaluate efficacy and safety of therapeutic hepatitis B virus (HBV) vaccine (mimogen-based)) Joint entecavir treatment in chronic hepatitis B patients.
详细描述
Eligible subjects are enrolled and assigned into 2 groups randomly with a 1:1 ratio:
- Therapeutic HBV vaccine Joint Entecavir group:Inject εPA-44 900μg at week 0, 3, 6, 9, 12, 15, 18, 21, 24, 28, 32, 36, 40, 44, 48 + Oral intake entecavir 0.5mg per day ;
- Empty liposome Joint Entecavir group:Inject empty liposome at week 0, 3, 6, 9, 12, 15, 18, 21, 24, 28, 32, 36, 40, 44, 48 + Oral intake entecavir 0.5mg per day.
The study cycle consists of screening and enrollment period (week -4~0), treatment and follow-up period (week 0-96).
