To be eligible for this study, patients must have the following documented:
1.Age > 18 years
2.Positive HBsAg for more than 6 months, positive HBeAg, detectable HBV DNA (patients must have >100,000 iu/ml (>500,000 copies/ml) as measured by PCR)
3.Elevated serum ALT > 1.1 x ULN but < 10X ULN
4.A liver biopsy obtained within the past 18 months (and more than 6 months after the end of any previous therapy for hepatitis B) demonstrating liver disease consistent with pre-cirrhotic chronic hepatitis B.
5.Negative urine pregnancy test (for women of childbearing potential) documented within the 48-hour period prior to the first dose of test drug. Additionally, all fertile males with partners of childbearing age and females must be using reliable contraception during the study and for 3 months after treatment completion.
