NCT00922207

Brief Summary

This 3 arm study will assess the efficacy and safety of PEGASYS alone, or in combination with Adefovir or Entecavir in patients with HBeAg positive chronic hepatitis B. Patients will be randomized to receive 1)PEGASYS 180 micrograms sc weekly for 48 weeks + placebo from weeks -4 to 2;2)PEGASYS 180 micrograms sc weekly for 48 weeks + Adefovir from weeks -4 to 2; or 3)PEGASYS 180 micrograms sc weekly for 48 weeks + Entecavir from weeks -4 to 2. Treatment will be followed by 24 weeks of treatment-free follow-up.The anticipated time on study treatment is 1 year, and the target sample size is 100-500 individuals.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants With Hepatitis B e-Antigen (HBeAg) Seroconversion at 100 Weeks After Start of Treatment

    HBeAg seroconversion was defined as the absence of HBeAg (a negative result for HBeAg) and the presence of hepatitis B e-antibody (anti-HBe/HBeAb) (a positive result for anti-HBe).

    Week 100

Secondary Outcomes (6)

  • Change From Baseline in Hepatitis B Virus Deoxyribonucleic Acid (HBV DNA) Levels at Weeks 4, 8, 16, 28, 40, 52, 64, 76, 88, and 100

    Baseline, Weeks 4, 8, 16, 28, 40, 52, 64, 76, 88, and 100

  • Percentage of Participants Who Were HBeAg Negative

    Baseline, Weeks 4, 8, 16, 28, 40, 52, 64, 76, 88, and 100

  • Percentage of Participant Who Were Both Hepatitis B Surface Antigen (HBsAg) Negative and Hepatitis B Surface Antibody (Anti-HBs/HBsAb) Positive

    Baseline, Weeks 4, 8, 16, 28, 40, 52, 64, 76, 88, and 100

  • Percentage of Participant With Normal Alanine Aminotransferase (ALT) Levels
