Chronic Hepatitis B
Conditions
Brief summary
This is a prospective, randomized, multicenter, open-label study. After more than 24 weeks NA treatment, HBeAg positive CHB patients who achieved HBV DNA\<1000copies/ml but HBeAb negative, will be randomized (1:1) into 2 study arms as follows: Arm A: Peginterferon alfa-2a 180μg /wk plus NA 1 piece qd for 48 weeks Arm B: Entecavir 0.5mg qd for 48 weeks

Eligibility
Inclusion criteria
1. Male and female patients with age ≥18 and ≤65 years; 2. There should be evidences that HBsAg and HBeAg have been positive for more than 6 months with HBsAb and HBeAb negative before treated with Entecavir; 3. Treated with NA for more than 24 weeks and achieve HBV DNA\<1000copies/ml with HBeAb negative; 4. Women without ongoing pregnancy or breast feeding and willing to take an effective contraceptive measure during the treatment 5. Agree to participate in the study and sign the patient informed consent.
Exclusion criteria

Evidence of decompensated liver disease (Child-Pugh scores \>5). Child-Pugh \>5 means that, if one of the following 6 conditions is met, the patient has to be excluded: 1. Serum albumin \<35 g/L; 2. Prothrombine time prolonged≥ 4 seconds or PTA \< 60%; 3. Serum bilirubin \> 34 µmol/L; 4. History of encephalopathy; 5. Ascites 4.

Pregnant or breast-feeding Women 6. ANC\<1.5x 10\^9/L or PLT\<90x 10\^9/L 7. Consuming alcohol in excess of 20g/day for women and 30g/day for men within 6 months prior to enrollment 8. History of severe psychiatric disease, especially depression. Severe psychiatric disease is defined as major depression or psychosis that treated with antidepressant medication or a major tranquilizer at therapeutic doses respectively at any time prior to 3 months or any history of the following: a suicidal attempt hospitalization for psychiatric disease, or a period of disability due to a psychiatric disease 9. History of immunologically mediated disease, (e.g., inflammatory bowel disease, idiopathic thrombocytopenic purpura, lupus erythematosus, autoimmune hemolytic anemia, scleroderma, rheumatoid arthritis etc.) 10. History of esophageal varices bleeding or other evidence of esophageal varices bleeding or other symptoms consistent with decompensated liver disease 11. History of chronic pulmonary disease associated with functional limitation 12. History of severe cardiac disease (e.g., NYHA Functional Class III or IV, myocardial infarction within 6 months, ventricular tachyarrhythmias requiring ongoing treatment, unstable angina or other significant cardiovascular diseases) 13. Hemodialysis patients or patients with renal insufficiency 14. History of a severe seizure disorder or current anticonvulsant use 15. Major organ transplantation or other evidence of severe illness, malignancy, or any other conditions, which would make the patient, in the opinion of the investigator, unsuitable for the study 16. History of thyroid disease poorly controlled on prescribed medications 17. Evidence of severe retinopathy or clinically relevant ophthalmologic disorder 18. History of other severe disease or evidence of other severe disease or any other illness or conditions that the investigator believe that patients are not suitable to join in the study 19.
