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).
