5. HBeAg negative and anti-HBeAg positive.
6. HBV DNA ≥ 104 copies/mL.
7. All women of childbearing potential must have a negative urine pregnancy test prior to enrolment.

Exclusion Criteria:

1. Decompensated liver disease (Child-Pugh-Score >6).
2. Any sign of liver cirrhosis (histological, ultra sound, biochemical).
3. Co-infected with hepatitis C virus (HCV), hepatitis D virus (HDV), or HIV.
4. ALT > 6 ULN.
5. Creatinine clearance < 60 mL/min.
6. Total bilirubin > 2 mg/dL.
7. Pre-treatment with nucleoside-analogues (lamivudine, telbivudine, entecavir) less than 6 months prior to the first dosing of the investigational medicinal products. Pre-treatment with nucleotide-analogues and interferons is allowed.
8. History of hepatocellular carcinoma (HCC) or findings suggestive of possible HCC, such as suspicious foci on imaging studies or elevated serum alpha-fetoprotein (AFP) levels. In patients with such findings, HCC will be ruled-out prior to screening for the present study.
9. One or more additional known primary or secondary causes of liver disease, other than hepatitis B (e.g., alcoholism, autoimmune hepatitis, malignancy with hepatic involvement, hemochromatosis, alpha-1 antitrypsin deficiency, Wilson's Disease, other congenital or metabolic conditions affecting the liver, e.g. congestive heart failure or other severe cardiopulmonary disease). Patients with Gilbert's syndrome and Dubin-Johnson syndrome, two benign disorders associated with low-grade hyperbilirubinemia can be enrolled into the trial.
