About this trial
This is a pilot study to determine the safety and efficacy of a novel adjuvanted hepatitis B virus (HBV) vaccine formulated as a potential therapeutic vaccine against chronic HBV infection. An ongoing human clinical trial of this HBV vaccine in a prophylactic setting has confirmed this vaccine to be more effective at inducing seroconversion as measured by development of Hepatitis B surface antibody (HBsAb) in poor responder subjects than the standard alum-adjuvanted HBV vaccine, providing promise that this new vaccine may also be able to induce HBV viral control and/or seroconversion in chronically infected subjects
