5. Study Description

Brief Summary
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.
Detailed Description
First stage(0-76 weeks): Eligible subjects are enrolled and assigned to 3 groups randomly in a 1:1:1 ratio: 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. 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. 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): In this follow-up stage the trial is open designed, and all the subjects completed the first stage study(0-76 weeks): Subjects with no virological response and no serological response in the first stage , and refuse to continue the this follow-up study, will be provided domestic Adefovir Dipivoxil for one year freely; Subjects with virological response but no serological response/with serological response but no virological response/neither virological nor serological response in the first stage, and be willing to continue the this follow-up study, will be treated by εPA-44 900 μg; Subjects with both virological and serological response, will be followed-up to 144 weeks with no Adefovir Dipivoxil or εPA-44 900 μg treatment. The definition of response is defined as below: Virological response: HBV DNA<2.93×10∧3IU/ml at 76 weeks; Serological response: serological conversion of HBeAg at 76 weeks.
