The purpose of this trial is to provide data of absence of inflammation in patient liver histology after long-term telbivudine treatment and thus help investigators to make a comprehensive judgment on treatment discontinuation in selected patients
Compensated Chronic Hepatitis B
||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||A Single-arm, Multicenter, Open-label, 52-week Treatment, Extension Study to CLDT600ACN04 Study to Evaluate the Efficacy (Including Histological Improvement) and Safety in Fourth to Sixth Year of Telbivudine Treatment in Patients With Chronic Hepatitis B
Primary Outcome Measures:
- To assess proportion of patients with absence of inflammation in liver biopsy at study entry and combine the histological assessment with serological evaluations. [ Time Frame: Visit 2 (week 1) ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- To assess the HBV DNA PCR negativity at 4th-6th year treatment with telbivudine (LDT), in selected patients who have completed study CLDT600ACN04 and will continue telbivudine treatment [ Time Frame: weeks 1, 24, 52 and 24 weeks post-treatment ] [ Designated as safety issue: No ]
- To evaluate the percentage of patients with HBeAg loss and/or gain of detectable level of HBeAb in HBeAg positive CHB at baseline of NV-02B-007 or NV-02B-015 studies [ Time Frame: weeks 24 and 52, 24 weeks post-treatment ] [ Designated as safety issue: No ]
- To evaluate percentage of patients with with HBsAg loss and/or HBsAg seroconversion [ Time Frame: weeks 24, 52 and 24 weeks post-treatment ] [ Designated as safety issue: No ]
- To evaluate the changes in Knodell inflammatory and fibrosis scores from biopsy at study entry compared to biopsy at baseline of studies NV-02B-007 and NV-02B-015 [ Time Frame: Visit 2 (week 1) ] [ Designated as safety issue: No ]
