Study Summary

Chronic hepatitis B virus (HBV) infection is a significant worldwide medical problem. GSK3228836 demonstrated target engagement in CHB participants who were not on treatment and in CHB participants on stable nucleos(t)ide therapy. This study is intended to evaluate if treatment with GSK3228836 can achieve sustained virologic response (SVR), that is hepatitis B virus surface antigen (HBsAg) less than (\<) lower limit of quantitation (LLOQ) and HBV deoxyribonucleic acid (DNA) \<LLOQ sustained for 24 weeks post-GSK3228836 treatment end. In addition, the study will also evaluate the safety, tolerability, pharmacokinetic and pharmacodynamic properties of GSK3228836 in the 4 dosing regimens. This study will assess the efficacy and safety of treatment with GSK3228836 in two populations of participants with CHB; participants on stable nucleos(t)ide treatment (Cohort 1) and participants who are not currently on nucleos(t)ide therapy (Cohort 2). For each population, participants will be randomized into one of the 4 different parallel arms to receive treatment. The study will consist of a screening, treatment, and post-treatment follow-up phase. Approximately, 440 participants will be enrolled in the study.

Primary Outcome

The SVR was a composite endpoint defined as Hepatitis B surface antigen (HBsAg) and Hepatitis B virus (HBV) Deoxyribonucleic acid (DNA) levels were less than (\<) Lower limit of quantitation (LLOQ) at the planned end of GSK3228836 treatment which is sustained for 24 weeks post-GSK3228836 treatment in the absence of rescue medication.
