Description of intervention(s) / exposure
Treatment: Drugs - Peg-IFN alfa-2a

Adult CHB Participants Treated With Peg-IFN Alfa-2a - Adult participants with CHB infection, and who have completed at least 24 weeks of Peg-IFN alfa-2a with/without nucleoside analogue therapy and at least 24 weeks of follow-up, will be included. Participants will be recruited from Roche clinical trials or general practice; no treatment will be administered in this non-interventional study.


Treatment: Drugs: Peg-IFN alfa-2a
Participants received Peg-IFN alfa-2a prior to enrollment for at least 24 weeks. Dosing was chosen according to standard of care or at the discretion of the treating physician.

Summary
Brief summary
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. The
follow-up of individuals 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 deoxyribonucleic acid (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 participants who previously have consented and donated RCR DNA
samples) and medical record capture.
