Participants in both Part 1 and 2 will receive a finite course of PBGENE-HBV.EXPERIMENTALAll participants will receive a finite course of multiple IV dose administrations of PBGENE-HBV. In Part 1, this will be done in a dose escalation manner which may be evaluated further in a Part 2 expansion cohort.

Interventions

NameTypeDescription
PBGENE-HBVBIOLOGICALPBGENE-HBV is an in vivo gene editing intervention based on a novel proprietary ARCUS® platform designed to potentially cure chronic hepatitis B virus (HBV) by eliminating cccDNA, the key source of replicating hepatitis B virus, while also inactivating integrated HBV DNA in hepatocytes.
