Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
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.
