HBRN: Immune Regulation and Costimulation in Natural History and Therapeutic Outcome of Chronic Hepatitis B
Trial status: Open for Enrollment
Why is this study being done?
Aim 1. Therapeutic HBV suppression will enhance antiviral immune effector responses and reduce immune inhibitory factors in participants with chronic hepatitis B. This study will also examine if antiviral therapy has a durable effect in host immune phenotype and define the immunological effect of interferon-alpha (IFNα) therapy in chronic HBV participants.
Aim 2. Antiviral immune effector and regulatory responses before, during and/or after therapy can predict long term therapeutic response.
