A Study of Combination or Sequential Treatment With PEGASYS (Peginterferon Alfa-2a) and Entecavir in Patients With HBeAg Positive Chronic Hepatitis B

Summary

This 2 arm study will assess the efficacy and safety of Pegasys in combination or sequential treatment with entecavir in patients with HBeAg positive chronic hepatitis B. Patients who have been pretreated with, and responded to, entecavir for 9 to 36 months were randomized to one of 2 groups, to receive Pegasys 180micrograms/week sc for 48 weeks + entecavir 0.5mg po daily for 8 weeks, or entecavir 0.5mg po daily for 48 weeks.
