HBRN: Immune Regulation and Costimulation in Natural History and Therapeutic Outcome of Chronic Hepatitis B
This trial is active, not recruiting.
|Sponsor||University of Pittsburgh|
|Collaborator||National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)|
|Start date||March 2013|
|End date||March 2016|
|Trial size||40 participants|
|Trial identifier||NCT01796457, DK082864 Immunology Treatment, U01DK082864|
This is an ancillary to the NIDDK-sponsored treatment trials titled: Combination Therapy of Pegylated Interferon Alfa-2a and Tenofovir Versus Tenofovir Monotherapy in Chronic Hepatitis B (NCT01369212) and Combination Entecavir and Peginterferon Therapy in HBeAg-Positive Immune-Tolerant Adults With Chronic Hepatitis B (NCT01369199).
This study will examine the balance between immune regulatory and effector responses in hepatitis B-infected participants enrolled in the HBRN's clinical trials (NCT01369212 and NCT01369199) to define natural history and treatment outcome.

|Principal investigator||Kyong-Mi Chang, MD|
|Description||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.|
