An Open-label, Observation Study to Evaluate the Durability of Antiviral Activity in Chronic Hepatitis B Patients Who Showed Complete Response in L-FMAU-301,L-FMAU-302 or L-FMAU-303 Trial


Inclusion Criteria:



1. The patients who have completed L-FMAU-301, L-FMAU-302 or L-FMAU-303.

2. Patients who have showed complete response (ALT normalization and HBV DNA <4,700
copies/mL in L-FMAU-301 or L-FMAU-302, in addition, HBeAg seroconverted to anti-HBe
at the last two visits in L-FMAU-301) after completion of L-FMAU-301 or L-FMAU-302
and treated with the clevudine.

3. Patients who have showed complete response (ALT normalization and HBV DNA <4,700
copies/mL, in addition HBeAg seroconverted to anti-HBe at the last two visits who
showed HBeAg positiv at baseline) after completion of L-FMAU-303

4. Patients who were able to give written informed consent prior to study start and to
comply with the study requirements.

5. Patients with bilirubin levels less than 2.0 mg/dL, prothrombin time of less than 1.7
(INR), and a serum albumin level of at least 3.5 g/dL at the last visit in
L-FMAU-301, L-FMAU-302 or L-FMAU-303.

Exclusion Criteria:

1. Patients who have showed complete response but previously treated with placebo in the
L-FMAU-301, L-FMAU-302.

2. Patients who were currently receiving antiviral, immunomodulatory or corticosteroid
therapy.

3. Patients previously treated with interferon, lamivudine, lobucavir, famciclovir,
adefovir or any other investigational nucleoside for HBV infection.

4. Patients with a history of ascites, variceal hemorrhage or hepatic encephalopathy.

5. Patients co-infected with HCV, HDV or HIV.

6. Patients with a liver mass (hemangioma, nodule), biliary diseases except asymptomatic
GB stone during the L-FMAU-301, L-FMAU-302 or L-FMAU-303.

7. Patients who were pregnant or breast-feeding.

8. Patients with a significant gastrointestinal, renal, hepatic (decompensated), biliary
diseases except asymptomatic GB stone, bronchopulmonary, neurological,
cardiovascular, oncologic or allergic disease. The patients with a benign tumor were
excluded if judged by an investigator that the continuation of study would be
interfered by benign tumor.

9. Patients who were not suitable to the study if judged by an investigator.
