The goal of this clinical trial is to learn about the action of Imdusiran (AB-729) in the liver of people with chronic hepatitis B. The main questions it aims to answer are: * how well is it working in the liver * how does Imdusiran affect the hepatitis B virus Participants will receive injections of Imdusiran, one injection every 8 weeks, for a total of 4 doses. They will also undergo 2 liver biopsies: one with the first dose of Imdusiran, and the second 8 weeks after the last dose of Imdusiran.
Background: Chronic hepatitis B virus (HBV) infection affects 292 million people worldwide; 887,000 die each year from cirrhosis, liver cancer, and related issues. Treatment options are limited. Objective: To test 2 drugs (VIR-2218 and peginterferon) in people with mild or inactive HBV infection. Eligibility: People aged 18 to 65 years with mild or inactive HBV infection. Design: Participants will be screened. They will have blood tests and an eye exam. They will have imaging scans of the liver to check the health of the liver. Participants will be in the study for over 2 years. VIR-2218 is an injection given under the skin of the stomach, upper arm, or thigh. Participants will come to the clinic to receive this injection once a month for 6 months. Peginterferon is also injected under the skin. Participants will have this shot once a week for 6 months. They may either inject themselves at home or come to the clinic to get the injections. Participants will get just the VIR-2218 for 3 months, then both shots for 3 months, then just the peginterferon for 3 months. Participants will have two 3-day stays in the hospital. Tests will include: Liver biopsy. A sample of tissue will be taken from their liver. After the procedure, participants will lie on their right side for 2 hours and then on their back for 4 hours. Fine needle aspiration. A small needle will be used to collect cells from the liver. After the last injection of peginterferon, follow-up visits will continue in the outpatient clinic every 4 to 12 weeks.

Hepatitis B virus (HBV) infection, especially chronic, is a significant worldwide medical problem. This is an exploratory study of the therapeutic mechanism of GSK3228836 in participants with chronic hepatitis B (CHB) on stable nucleos(t)ide therapy (which is the first line therapy for CHB).

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.

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.

This three-part, Phase 1 protocol will be the first clinical study of ABI-H2158. Parts 1 and 2 will be a Phase 1a, dose-ranging assessment of ABI-H2158 in healthy adult volunteers. If the dose-related safety, tolerability, and pharmacokinetics (PK) of ABI-H2158 in healthy volunteers are deemed satisfactory, then the study will advance to Part 3, a Phase 1b, dose-ranging assessment of ABI-H2158 in non-cirrhotic, CHB patients.
The TARGET-HBV study engages an observational research design to conduct a comprehensive review of outcomes for patients with CHB infection. The initial phase of the study that enrolled patients treated with tenofovir alafenamide (TAF) was successfully completed. The current protocol (Amendment 1) describes the second phase of the study that will engage research activities for patients being managed for CHB in usual clinical practice in the US and Canada. The study addresses important clinical questions regarding the management of CHB by collecting and analyzing data from patients at academic and community medical centers. TARGET-HBV creates a robust database of real-world data regarding the natural history, management, and health outcomes related to antiviral treatments used in clinical practice.
