- •Clinical history compatible with CHB
- •Detectable serum Hepatitis B Surface Antigen (HBsAg) at the Screening visit and at least 6 months prior
- •HBeAg-positive at the Screening visit
- •Hepatitis B 'e' Antibody (HBeAb)-negative at the Screening visit
- •History of evidence of chronic liver inflammation,
- •Elevated serum Alanine aminotransferase (ALT) level (1.3 - 10 x upper limit of normal (ULN)) at the Screening visit
- •Serum HBV DNA level ≥ 6 log10 copies/mL,
- •Chronic liver inflammation on previous liver biopsy within the previous 24 months.
排除标准
- •Co-infection with Hepatitis C Virus (HCV), Hepatitis D Virus (HDV), or Human Immunodeficiency Virus (HIV).
- •Has any of the following drug therapy:
- •Previously been treated in a trial with telbivudine
- •Received nucleoside or nucleotide therapy whether approved or investigational
- •Received any immunomodulatory treatment in the 12 months before Screening for this study.
- •Has a medical condition that required prolonged or frequent use of systemic acyclovir or famciclovir.
- •Has a medical condition that requires frequent or prolonged use of systemic corticosteroids although inhaled or intra-articular corticosteroids are allowed.
- •Has a medical condition requiring the chronic or prolonged use of potentially hepatotoxic drugs or nephrotoxic drugs.

结局指标
主要结局
Percentage of Participants Who Achieved HBV DNA Non-detectability With Peginterferon Alpha-2a Plus Telbivudine Combination Therapy Versus Peginterferon Alpha-2a Monotherapy
时间窗: At week 52
The original primary efficacy variable was the percentage of patients achieving HBV DNA non-detectability utilizing polymerase chain reaction (PCR) (threshold for detection 300 copies/mL); however, this analysis was not performed due to premature study termination.
Percentage of Participants With HBV DNA Non-detectability and Alanine Aminotransferase (ALT) Normalization at Week 12 and Week 24 in Participants With HBeAg-positive Chronic Hepatitis B (CHB)
时间窗: Weeks 12 and 24
The percentage of participants who achieved HBV DNA non-detectability using the COBAS Amplicor HBV Monitor assay utilizing polymerase chain reaction (PCR) (threshold for detection 300 copies/mL) and Alanine aminotransferase (ALT) normalization defined as ALT within normal limits on two successive visits for a patient with an elevated ALT (\>1.0 x upper limit normal) at baseline summarized at Weeks 12 and 24.
次要结局
- Change From Baseline in HBV DNA Concentration(Weeks 12 and 24)
- Percentage of Participants Who Experienced Virologic Breakthrough at Weeks 48 and 52(Weeks 48 and 52)
- Percentage of Participants With Hepatitis B 'e' Antigen (HBeAg) Loss and HBeAg Seroconversion(Weeks 18, 24, 48, 52 and Treatment completion (TC))
- Percentage of Participants Who Achieved HBV DNA Non-detectability With Telbivudine Monotherapy Versus Peginterferon Alpha-2a Monotherapy(Week 52)
- Percentage of Participants Who Achieved HBV DNA Non-detectability With Peginterferon Alpha-2a Plus Telbivudine Combination Therapy Versus Telbivudine Monotherapy(Week 52)
