A Study of PEGASYS (Peginterferon Alfa-2a (40KD)) in Patients With Lamivudine Resistant HBeAg-Negative Chronic Hepatitis B.

June 27, 2008 updated by: Hoffmann-La Roche

An Open Label Study to Evaluate the Effect of PEGASYS on ALT and HBV DNA Levels in Patients With Lamivudine-Resistant HbeAg-Negative Chronic Hepatitis B

This single arm study will evaluate the efficacy and safety of PEGASYS in patients with lamivudine resistant HBeAg negative chronic hepatitis B. Patients will receive PEGASYS 180 micrograms s.c. weekly for 48 weeks; following this, there will be a 48 week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.
