Brief summary

The purpose is to evaluate efficacy and safety of therapeutic 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

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) 1. 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 at week 80,83,86,89,92,95,98,101,104,108,112,116,120,124,128. 2. 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 as below: 1. Virological response: HBV DNA\<2.93×10∧3IU/ml at 76 weeks; 2. Serological response: serological conversion of HBeAg at 76 weeks.
