Outcome Measures

Primary Outcomes (2)

  • Efficacy: incident rate of the HBV DNA negativity (i.e. <300 copies/ml) by PCR

  • Safety: Laboratory tests, Adverse Events, Physical examination

Secondary Outcomes (5)

  • Efficacy:

  • Viral kinetics of HBV DNA suppression

  • Viral dynamic study over the first 12 weeks to define the nature of the anti-viral effect of Clevudine compared to Lamivudine.

  • Evaluation of the changes of ALT normalization rate and HBV serology over 48 weeks of treatment period

  • Evaluation of the proportion of patients with HBV DNA <300 copies/ml, median HBV DNA change from baseline(log10 copies/ml), the proportion of patients with normal ALT, and HBV serology over an additional 48 weeks of open label treatment

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Patient is between 18 and 60, inclusive.
  • Patient is HBV DNA positive with DNA levels at screening \>= 3 x 1,000,000 copies/mL.
  • Patient is documented to be HBsAg positive for \> 6 months and HBeAg positive.
  • Patient has AST and ALT levels which are \>= 1 times and \<= 10 times the upper limit of normal (x ULN).
  • Patient has bilirubin levels \<= 1.5 x ULN or bilirubin levels \> 1.5 x ULN with diagnosis of Gilbert's disease and conjugated bilirubin within normal limits.
  • Women of childbearing age must have a negative urine (b-HCG) pregnancy test before start of trial treatment.
  • Patient is able to give written informed consent prior to study start and to comply with the study requirements.

You may not qualify if:

  • Patient is currently receiving antiviral, immunomodulatory or corticosteroid therapy.
  • Patients previously treated with lamivudine, lobucavir, adefovir, famciclovir, or any other investigational nucleoside for HBV infection.
  • Previous treatment with interferon must have ended at least 6 months prior to the screening visit.
  • Patient has a history of ascites, variceal hemorrhage or hepatic encephalopathy.
  • Patient is co-infected with HCV or HIV.
  • Patient has evidence of decompensated cirrhosis or hepatocellular carcinoma (alpha fetoprotein).
  • Patient is pregnant or breast-feeding.
  • Patient is unwilling to use an "effective" method of contraception during the study and for up to 3 months after the use of study drug ceases. For males, condoms should be used. Females must be surgically sterile (via hysterectomy or bilateral tubal ligation), post-menopausal, or using at least a medically acceptable barrier method of contraception (i.e., IUD, barrier methods with spermicide or abstinence).
  • Patient has a clinically relevant history of abuse of alcohol or drugs.
  • Patient has a significant gastrointestinal, renal, hepatic (decompensated), bronchopulmonary, neurological, cardiovascular, oncologic or allergic disease.
  • Subjects who are currently participating in another investigational study or has been taking any investigational drug within the last 4 weeks prior to Screening Visit.
  • Subjects who are taking any traditional Chinese medication, or has been taking any traditional Chinese medication within the last 2 weeks prior to Screening Visit.
  • Any criteria, which, in the opinion of the investigator, suggests that the subject would not be compliant with the study protocol.
