Inclusion Criteria

Signed written informed consent 1) Freely given informed consent must be obtained from subjects prior to clinical trial participation, including informed consent for any screening procedures conducted to establish subject eligibility for the study; 2) Patients with chronic HBV infection (detectable HBsAg at screening and for at least 24 weeks prior to screening, or detectable HBsAg for < 24 weeks and negative for IgM core antibody), HBeAg positive or negative; 3) ALT > ULN and ≤ 10 x ULN and HBVDNA >/= 2000 IU/ml at screening and at least once ≥ 12 weeks prior to screening; 4) Fibrosis stage at liver histology >/= 2 by METAVIR scoring in a biopsy performed no more than 6 months before study entry; 5) Subjects must have compensated liver function and must meet all of the following criteria: International Normalization Ratio (INR) ≤ 1.5 Serum albumin ≥ 3 g/dL (≥ 30 g/L) Serum total bilirubin ≤ 2.5 mg/dL (≤ 42.75 μmol/L) 6) Nucleoside- and Nucleotide-naive subjects (previous recombinant interferon or pegylated interferon based therapy is admitted if it was withdrawn 6 months before study entry; 7) Males and females ≥ 18 years of age Women of childbearing potential (WOCBP) must be using an adequate method of contraception to avoid pregnancy throughout the study (and for up to 6 weeks after the last dose of investigational product) in such a manner that the risk of pregnancy is minimized. WOCBP include any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation or bilateral oophorectomy) or is not postmenopausal. WOCBP must have a negative serum or urine pregnancy test within 72 hours prior to the start of investigational product.

Exclusion Criteria

1) WOCBP who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period and for up to 6 weeks after the last dose of investigational product; 2) WOCBP using a prohibited contraceptive method. At this time there are no known contraindicated contraceptives to entecavir; 3) Women who are pregnant or breastfeeding; 4) Women with a positive pregnancy test on enrollment or prior to investigational product administration; Target Disease Exceptions 5) Evidence of clinical condition correlated to liver disease for which, in the Investigator s opinion, NAs are mandatory; 6) Evidence of decompensated cirrhosis including but not limited to: variceal bleeding; hepatic encephalopathy or ascites requiring management with diuretics or paracentesis; 7) Coinfection with HIV, hepatitis C virus (coinfection is defined as HCV Ab positive with detectable HCV RNA by PCR) or hepatitis D virus; Medical History and Concurrent Diseases 8) Recent history of pancreatitis (within 24 weeks prior to the first dose of study medication); 9) Currently abusing illegal drugs or alcohol sufficient, in the Investigator s opinion, to prevent adequate compliance with study therapy or to increase the risk of hepatotoxicity or pancreatitis; 10) Other serious medical conditions that might preclude completion of this study or that require chronic administration of prohibited medications (see Exclusion Criterion 19); Physical and Laboratory Test Findings 11) Serum alpha fetoprotein (AFP) level > 100 ng/mL; If the AFP level is between 21 and 100 ng/mL, it must be repeated prior to randomization. If the repeat AFP level is between 21 and 100 ng/mL, and if ultrasonography or computerized tomography (CT) of the liver performed prior to the first dose of study medication does not demonstrate a focal lesion suggestive of carcinoma, the subject may be dosed in the study; Allergies and Adverse Drug Reactions 12) Known history of allergy to NAs;
