Brief Summary:
A Phase II Randomized, Double-blind, Placebo-controlled, Multi-center, Dose-effect Relationship Study of Hepalatide for Injection Combined with Pegylated Interferon in Subjects with HBeAg-positive Chronic Hepatitis B

Condition or disease Intervention/treatment Phase
Hepatitis B, Chronic Drug: Hepalatide 2.1mg Drug: Hepalatide 4.2mg Drug: Hepalatide 6.3mg Drug: placebo 2.1mg Drug: placebo 4.2mg Drug: placebo 6.3mg Drug: Pegylated Interferon Phase 2

Detailed Description:
The study is a 4-arm parallel design, randomized, double-blind, placebo-controlled, multicenter, dose-effect relationship, phase II clinical trial. The study is designed to assess efficacy and safety of 3 Doses of hepalatide in Combination with Pegylated Interferon Compared to Pegylated Interferon Alone in patients with Chronic Hepatitis B .Subjects will be randomly assigned to the 2.1mg, 4.2mg, and 6.3mg dose groups , 32 subjects in each group . The subjects in each dose group will be randomly and double-blindly administered the corresponding dose of trial drug or placebo in a ratio of 3:1. The subjects in each dose group who received placebo treatment combine as the placebo group. All subjects will receive Pegylated Interferon treatment for 28 weeks as the basic treatment,trial drug or placebo treatment for 24 weeks continuously , followed by a safety follow-up for 4 weeks.
