With several drugs in use that inhibit the hepatitis B virus polymerases (nucleos(t)ide analogues (or NUCs)), some argue that new direct-acting antiviral drugs, and new NUCs in particular, are not necessary. Here, we make the counter-argument that additional direct-acting antiviral drugs that can potently suppress hepatitis B virus replication, ideally via distinct mechanisms, are still needed and can provide additional therapeutic benefits.
