A Study of Peginterferon Alfa-2a [PEGASYS] in Patients With Chronic Hepatitis B Who Are HBeAg Positive

Phase 4
Completed
Conditions
Hepatitis B, Chronic
Interventions
Drug: peginterferon alfa-2a [PEGASYS]
Registration Number
NCT01086085
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This open-label, multi-center study will evaluate the effect on the quantitative HBsAg reduction of peginterferon alfa-2a \[PEGASYS\] in patients with HBeAg positive chronic hepatitis B. Patients will receive PEGASYS 180 mcg sc once weekly. After 24 weeks of treatment, rapid responders will receive another 24 weeks of treatment. After 24 weeks of treatment, slow responders will be randomized to another 24 or 72 weeks of PEGASYS monotherapy, or to 72 weeks PEGASYS plus 36 weeks adefovir (10 mg, po once daily, starting from week 29 of PEGASYS treatment). The anticipated time on study drug is \>2 years.
