简要总结

The purpose is to evaluate efficacy and safety of therapeutic Hepatitis B Virus(HBV) vaccine (mimogen-based) treatment in chronic hepatitis B patients and to explore the most effective dosage and provide the rational for optimal dosing schedule.

详细描述

First stage(0-76 weeks):

Eligible subjects are enrolled and assigned to 3 groups randomly in a 1:1:1 ratio:

  1. εPA-44 600μg group:Subcutaneous inject εPA-44 600μg at week 0, 4, 8, 12, 20, 28;Polyene Phosphatidylcholine Capsules will be taken orally beginning in week 28.
  2. εPA-44 900μg group:Subcutaneous inject εPA-44 900μg at week 0, 4, 8, 12, 20, 28;Polyene Phosphatidylcholine Capsules will be taken orally beginning in week 28.
  3. Placebo control group:Subcutaneous inject empty liposome at week 0, 4, 8, 12, 20, 28;Polyene Phosphatidylcholine Capsules will be taken orally beginning in week 28.

The study cycle consists of screening and enrollment period (week -6-0), treatment period (week 0-28) and follow-up period (week 28-76).

Second stage(76-144 weeks):
