The purpose of this study is to evaluate the safety and antiviral activity of clevudine 30 mg QD for treatment of longer period (24 weeks) in patients chronically infected with HBV.

Sex: All

Volunteers: No Healthy Volunteers

1)had received no additional therapy since completion of 24-week treatment of clevudine and 2)experienced a >= 1 log10 decrease from baseline in HBV DNA at Week 48

Exclusion criteria

1. Patient with HBeAg seroconverted to anti-HBe at the last 2 consecutive visits (one month apart) in L-FMAU-201 study.
2. Patient who was currently receiving antiviral, immunomodulatory or corticosteroid therapy.

4. Patient who had a history of ascites, variceal hemorrhage or hepatic encephalopathy.
5. Patient who was co-infected with HCV, HDV or HIV.
6. Patient with clinical evidence of cirrhosis or hepatocellular carcinoma (®-Fetoprotein)Evaluation was based on alpha-fetoprotein primarily. If alpha-fetoprotein level was suggestive of cirrhosis or hepatocellular carcinoma, confirmation was made with ultrasonography etc.
7. Patient who was pregnant or breast-feeding.
8. Patient who was unwilling to use an "effective" method of contraception during treatment period and for up to 3 months after cessation of therapy. For males, condoms should be used.

10. Patient who had a significant gastrointestinal, renal, hepatic (decompensated), bronchopulmonary, neurological, cardiovascular, oncologic or allergic disease.
11. Patient who had creatinine clearance less than 60mL/min as estimated by the following formula:

(140-age in years) (body weight [kg])/(72) (serum creatinine [mg/dL]) [Note: multiply estimates by 0.85 for women]
