This Phase 4 study is designed for the collection of blood biomarker samples from participants who have completed CHB treatment with at least 24 weeks of a pegylated interferon alfa-2a (Peg-IFN alfa-2a) containing regimen and at least 24 weeks post-treatment follow-up. Participants may be enrolled from historical studies supported or sponsored by Roche, ongoing studies supported or sponsored by Roche, or from general medical practice.

Procedures will include blood sample collection (not applicable for participants who previously have consented and donated RCR DNA samples) and medical record capture.
