Future therapy for hepatitis B virus infection

Abstract

We can now control hepatitis B virus infection by continuously administering nucleoside and nucleotide analogues such as entecavir and tenofovir. These drugs are generally safe and sufficiently effective, but future drugs are needed that can show off-treatment efficacy—in other words, eradication of latent hepatitis B virus DNA (covalently closed circular DNA) in the hepatocytes. This article is an overview of new drugs under development and some novel strategies to inhibit hepatitis B virus proliferation.
