Clinical Trial Summary

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