Study Details

Study Description

Brief Summary

A randomized, parallel, multicenter, active-controlled with 48 weeks of treatment period. Patients will be randomized to receive clevudine alone for 48 weeks or clevudine for 24 weeks followed by 24 weeks of clevudine in addition to monthly HBV vaccination.The purpose of this study is to investigate efficacy of combination of clevudine and HBV vaccine over clevudine alone in patients with chronic hepatitis B infection.

Outcome Measures

Primary Outcome Measures

  1. Antiviral Activity: Proportion of patients with HBeAg loss [Screening, Day1(predose), every 4 weeks during treatment period(48weeks)]

  2. Safety Endpoints:Laboratory tests, Adverse Events, Vital signs, ECG [Screening, Day1(predose), every 4 weeks during treatment period(48weeks), ECG: screening, Week48]

Secondary Outcome Measures

  1. Proportion of patients with HBV DNA below LOD, Biochemical improvement, Proportion of patients with seroconversion [Screening, Day1(predose), every 4 weeks during treatment period(48weeks)]

  2. Immunological endpoints: Alterations in immunological parameters before, after therapy, particularly with regards to the proliferative a [Day1(predose), Week 8, 16, 24, 28, 32, 40 and 48]
