Core Tip
Core Tip: Despite preventive vaccination and effective antiviral drugs, approximately 300 million people worldwide are at risk of liver-related morbidity and mortality from hepatitis B virus (HBV) infection. In the search for more effective strategies, research has focused on two broad categories of therapeutic intervention. First, direct-acting antivirals that interrupt various stages of the HBV life cycle are yielding promising results in clinical trials that show suppression of the HBV antigen load. Second, the need to address depleted immune responses and revive the tolerogenic liver microenvironment has brought immunotherapies to the forefront. It is likely that an upcoming treatment that combines agents from both classes will achieve HBV elimination.
