This study is an open-label, 2-Part (Single Ascending Dose [Part 1] And Dose Expansion) study that will evaluate the safety of EPI-003 administered to patients with chronic infection with HBV (CHB). EPI-003 is a liver-targeted antiviral therapeutic for intravenous (IV) injection that is capable of precise epigenetic modifications of the HBV genome without causing mutations in the gene sequence itself. This study is designed to determine the safety and pharmacokinetic (PK) and pharmacodynamic (PD) profile of EPI-003 in this patient population.
