Brief summary

This is a Phase Ib/II, multicenter, randomized, dose-escalation study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of LW231 in participants with chronic hepatitis B virus (HBV) infection. The trial will include multiple-dose regimens of LW231 and assess LW231 in combination with NUCs.

Primary

Change from baseline in HBV DNA Viral Load Assay4 weeks

Secondary

MeasureTime frameDescription
Number of Participants With Adverse Events (AEs)up to 28 weeksAn adverse event (AE) was defined as any untoward medical occurrence in a participant who was administered a pharmaceutical product (including investigational drug) during the course of a clinical investigation. An AE could therefore be any unfavorable and unintended sign (including abnormal laboratory findings), symptom, or disease that was temporally associated with the use of the investigational product, regardless of whether it was considered to be related to the investigational product or not.
Change from baseline in HBsAgUp to 28 weeks
Maximum Plasma Concentration (Cmax) of LW231Up to 28 Weeks
Area Under the Curve From Time 0 to the Last Measurable Concentration (AUClast) of LW231Up to 28 weeks
