Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This open-label, randomized, parallel-arm study will assess the early immunologic response in treatment-naïve Asian male patients with chronic hepatitis B after initiation of treatment with Pegasys or tenofovir or Pegasys plus tenofovir. Patients will be randomized to one of 4 cohorts to receive either Pegasys (360mcg subcutaneously weekly) or tenofovir (300mg orally daily) or both or no treatment for 2 weeks. After 2 weeks on study treatment, patients may opt to receive standard of care treatment with Pegasys. Target sample size is \<50.

This report describes the early effects of IFNα treatment on immune and viral biomarkers in HBeAg+ CHB patients. The results show that PegIFNα-induced innate immune activation directly benefits from the suppression of HBV replication.
