Study in Japan of the Safety And Antiviral Activity in Adults With Chronic Hepatitis B Current Lamivudine Therapy

A Phase II Study in Japan of the Safety And Antiviral Activity of Entecavir (BMS-200475) in Adults With Chronic Hepatitis B With Incomplete Response to Current Lamivudine Therapy

The objectives are to demonstrate that entecavir has antiviral activity undetectable HBV DNA measured, the Roche AmplicorTM PCR at Week 48, and to assess the safety and the pharmacokinetic of entecavir in Japanese patients with hepatitis B who have an incomplete response to current lamivudine therapy

  2. Patient who have received lamivudine therapy for 24 weeks or more, or patient who have documented YMDD mutation or other lamivudine-resistant mutation while on lamivudine
  3. Documented HBV Viremia ≥ 10*5: copies/mL

• ALT in the range of 1.3 to 10 x ULN

• Subjects must have well-compensated liver disease a) value
