  Purpose

This phase 4 study is designed for the collection of blood biomarker samples fro m patients who have completed chronic hepatitis B treatment with at least 25 wee ks of a Pegasys (peginterferon alfa 2a) containing regimen and at least 24 weeks post-treatment follow-up. Patients may be enrolled from historical studies supp orted or sponsored by Roche, ongoing studies supported or sponsored by Roche or from general medical practice. The follow-up of patients who choose to participa te in this study will be in accordance with the ongoing studies or with the gene ral medical practice of the physician. Data from whole blood DNA samples collect ed in the GV28555 study or available from previously collected Roche Clinical Re pository (RCR) samples will be used for combined analysis with data from other a pplicable studies. Procedures will include blood sample collection (not applicab le for patients who previously have consented and donated RCR DNA samples) and m edical record capture.

Primary Outcome Measures:
  • Change in HBV DNA (quantitative PCR Test in iU/ml) [ Time Frame: from baseline to end of follow-up ] [ Designated as safety issue: No ]
  • Change in HBsAg/anti-HBs [ Time Frame: from baseline to end of follow-up ] [ Designated as safety issue: No ]
  • Change in HBeAg/anti-HBe [ Time Frame: from baseline to end of follow-up ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
