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 e antigen (HBeAg)-positive chronic hepatitis B virus (HBV) infection in children and adolescents with normal alanine aminotransferase (ALT) levels constitutes a substantial population in China, yet the optimal timing for antiviral therapy remains unclear. This prospective, real-world study, conducted as the primary centre of the Sprout Project, evaluated the hepatitis B surface antigen (HBsAg) loss rate and viral-immune dynamics of pegylated interferon α (PEG-IFN-α) treatment in 85 chronic HBV patients aged 3-18 years over a 24-month period. A total of 27 HBeAg-positive, ALT-normal patients were selected for analysis. Patients were treated with a combination of PEG-IFN-α and entecavir. After 24 months, the overall HBsAg loss rate was 48.15%, with 47.37% in the immune-tolerant phase and 50% in the grey zone phase. Among those who cleared HBsAg, 84.62% had ALT elevation prior to anti-HBsAg antibody (HBsAb) seroconversion, which occurred 28-400 days before HBsAg loss. While HBsAg and HBV DNA were cleared by 24 months in the HBsAg loss group, 23.08% of children remained HBeAg-positive. Notably, 61.54% developed detectable HBsAb prior to HBsAg loss. Children aged 3-7 years had significantly higher clearance rates than those aged 8-18 years. These findings support the effectiveness of PEG-IFN-α combined with nucleos(t)ide analogs in achieving high HBsAg loss rates in young, HBeAg-positive, ALT-normal chronic HBV children and adolescents, with immune activation potentially preceding ALT elevation, and offers valuable insights into the viral-immune dynamics during treatment, highlighting the potential of antiviral therapy in this population.

The remodeling of B-cell subsets was correlated with the clearance of hepatitis B antigen during pegylated IFN α-2a therapy in CHB patients

Article

Author: Wu, Zeqian ; Tan, Lei ; Mo, Zhishuo ; Zhu, Jianyun ; Gao, Zhiliang ; Gan, Weiqiang

BACKGROUND:

B-cell may participate in the cellular immune process of hepatitis B antigen clearance. However, the function and specific mechanism of B-cell during interferon-pegylated interferon α-2a (Peg-IFN-α) treatment in chronic hepatitis B (CHB) patients have not yet been described.

METHODS:

A total of 150 CHB patients enrolled in this study, who received 48 weeks of Peg-IFN α treatment. The differentiation clusters CD19, CD24, CD27, CD38, CD40, and CD80 of B cell surface markers in CHB patients were detected by flow cytometry. Spearman correlation and Logistic regression analysis were performed for the analysis.

RESULTS:

The clearance rate of HBsAg increased significantly with the duration of Peg-IFN-α treatment, reaching 32.2% by 48 weeks. During the Peg-IFN-α therapy, the frequency of B-cell and its subsets increased significantly. However, we did not observe any significant difference in the frequency of the B-cell and its subsets in patients with or without HBsAg clearance after 48 weeks Peg-IFN-α treatment. The change in HBsAg value was negatively related to the change in plasmablasts (CD19⁺CD38⁺) level before and after 48 weeks treatment (r = -0.326, p = 0.006). Moreover, the results showed that HBsAg <288.70 IU/mL at baseline and HBsAg <58.05 IU/mL at 12 weeks were strong predictors of HBsAg clearance in patients with 48 weeks Peg-IFN-α treatment.

CONCLUSION:

The remodeling of B cell subsets, especially plasmablasts (CD19⁺CD38⁺), during Peg-IFN-α treatment was closed associated with the clearance of hepatitis B antigen.

Arbutus Announces Four Abstracts Accepted for Presentation at AASLD - The Liver Meeting® 2025

Multiple abstracts accepted featuring imdusiran clinical data – highlighting progress toward a potential functional cure for chronic hepatitis B virus AB-101 clinical data abstract recognized as a Poster of Distinction WARMINSTER, Pa., Oct. 07, 2025 (GLOBE NEWSWIRE) -- Arbutus Biopharma Corporation (Nasdaq: ABUS) (“Arbutus” or the “Company”), a clinical-stage biopharmaceutical company focused on infectious disease, today announced that three abstracts featuring imdusiran data and one abstract featuring AB-101 data, have been accepted for poster presentations at the American Association for the Study of Liver Diseases (“AASLD”) – The Liver Meeting 2025, taking place November 7–11 in Washington, DC. Notably, the AB-101 abstract has been selected as a Poster of Distinction. Regular Abstracts Accepted as Poster Presentations: Publication Number: 1160Presentation Title: Imdusiran (AB-729) is safe and well-tolerated after repeat dosing in chronic hepatitis B patients: An integrated safety analysis of Phase 1 and 2 imdusiran clinical trialsPresenter: Tilly Varughese, MD, Medical Director, Clinical Development, Arbutus BiopharmaDate and Time: November 7, 2025, 8:00 am - 5:00 pm ETKey Findings: Imdusiran therapy in patients with chronic hepatitis B virus (“cHBV”) was safe and well tolerated when administered at both 60 mg and 90 mg dose levels every 8 weeks for 4 – 6 doses (24 – 48 weeks) and through up to 48 weeks of follow up after imdusiran dosing. Publication Number: 1244Presentation Title: IM-PROVE I: Hepatitis B virus (“HBV”) genotype responsiveness to pegylated interferon alfa-2a may be enhanced with imdusiran combination treatmentPresenter: Emily Thi, Senior Director, Immunobiology and Biomarkers Research, Arbutus BiopharmaDate and Time: November 7, 2025, 8:00 am - 5:00 pm ETKey Findings: In this limited dataset, the majority of subjects who achieved HBsAg response during pegylated interferon alfa-2a (“IFN”) treatment with or following imdusiran dosing were genotype B or C. These findings contrast with historical data from IFN therapy and suggest that imdusiran may enhance IFN responsiveness in cHBV patients with specific HBV genotypes. Further studies in larger cohorts are warranted to confirm these observations. Publication Number: 1184Presentation Title: Elevated soluble immune biomarkers in subjects with HBsAg loss after treatment with imdusiran and immunotherapeutic agents in the IM-PROVE I and IM-PROVE II studies Presenter: Emily Thi, Senior Director, Immunobiology and Biomarkers Research, Arbutus BiopharmaDate and Time: November 7, 2025, 8:00 am - 5:00 pm ETKey Findings: Imdusiran treatment is associated with increases in soluble immune biomarkers in both IM-PROVE I and IM-PROVE II studies. In subjects who lost HBsAg and had anti-HBs antibodies, a greater breadth and magnitude of immune biomarker increases were observed in IM-PROVE I subjects compared to IM-PROVE II. In both studies, subjects who showed increases in soluble immune biomarkers on-treatment met nucleos(t)ide analogue (“NA”) therapy discontinuation criteria and had baseline HBsAg ≤1000 IU/mL. Poster of DistinctionPublication Number: 1123Presentation Title: Safety, tolerability, pharmacokinetics and pharmacodynamics of multiple doses of AB-101, a small-molecule PD-L1 inhibitor, in chronic hepatitis B patientsPresenter: Tilly Varughese, MD, Medical Director, Clinical Development, Arbutus BiopharmaDate and Time: November 7, 2025, 8:00 am - 5:00 pm ET. The poster will remain available for the full duration of the conference.Key Findings: Oral doses of AB-101 up to 30 mg QD for 28 days were generally well tolerated in NA-suppressed cHBV patients. Preliminary interim pharmacodynamic data indicate dose-related increases in PD-L1 receptor occupancy, with 83% mean maximal receptor occupancy at the 30 mg dose. Cohort 3B is ongoing and all available data, including safety, PK, receptor occupancy and HBV biomarkers, will be presented. The regular accepted abstracts are available to the public on the AASLD website and will be published in the October supplement of HEPATOLOGY. The poster presentations will be available on the AASLD website beginning November 7, 2025 at 8:00 am ET and will also be found on Arbutus’ website in the Publications section at https://www.arbutusbio.com/publications/. About Imdusiran (AB-729) Imdusiran is an RNAi therapeutic specifically designed to reduce all hepatitis B viral proteins and antigens including HBsAg, which is thought to be a key prerequisite to enable reawakening of a patient’s immune system to control the virus. Imdusiran targets hepatocytes using Arbutus’ novel covalently conjugated N-Acetylgalactosamine (“GalNAc”) delivery technology enabling subcutaneous delivery. To date, Arbutus has reported a total of eight patients with cHBV who have achieved a functional cure following treatment with imdusiran and NA therapy in combination with either IFN or low dose nivolumab plus an immunotherapeutic. Clinical data generated thus far has shown imdusiran to be generally safe and well-tolerated, while also providing meaningful reductions in HBsAg and hepatitis B virus DNA. About AB-101 AB-101 is an oral PD-L1 inhibitor candidate that is designed to allow for controlled checkpoint blockade while minimizing the systemic safety issues typically seen with checkpoint antibody therapies. Immune checkpoints such as PD-1/PD-L1 play an important role in the induction and maintenance of immune tolerance and in T-cell activation, for example against HBV. In Arbutus’ ongoing Phase 1a/1b clinical trial, AB-101 has been generally safe and well-tolerated with evidence of high receptor occupancy. About HBV Hepatitis B is a potentially life-threatening liver infection caused by HBV. HBV can cause chronic infection which leads to a higher risk of death from cirrhosis and liver cancer. cHBV infection represents a significant unmet medical need. The World Health Organization estimates that over 250 million people worldwide suffer from cHBV infection, while other estimates indicate that approximately 2 million people in the United States suffer from cHBV infection. Approximately 1.1 million people die every year from complications related to cHBV infection despite the availability of effective vaccines and current treatment options. About Arbutus Arbutus Biopharma Corporation (Nasdaq: ABUS) is a clinical-stage biopharmaceutical company focused on infectious disease. The Company is currently developing imdusiran (AB-729) and an oral PD-L1 inhibitor (AB-101) for the treatment of cHBV infection. The Company is also consulting closely with and supporting its exclusive licensee, Genevant Sciences, to protect and defend its intellectual property, which is the subject of on-going lawsuits against Moderna and Pfizer/BioNTech for use of Arbutus’s patented LNP technology in their COVID-19 vaccines.

Virion Therapeutics Provides Update on its VRON-0200 Clinical Development Program for HBV Functional Cure on World Hepatitis Day 2025

This “Spark and Fan” treatment strategy could potentially offer a simple and well tolerated solution for a wide range of future HBV functional cure regimens for patients worldwide.” — Dr. Sue Currie, COO, Virion PHILADELPHIA, PA, UNITED STATES, July 28, 2025 / EINPresswire.com / -- Virion Therapeutics, LLC, a clinical-stage biotechnology company, developing novel T cell-based immunotherapies that utilize first-in-class checkpoint modifiers, today, on World Hepatitis Day, provided a corporate update highlighting continued progress across its functional cure program for chronic hepatitis B virus (CHB). KEY PROGRAM HIGHLIGHTS o VRON-0200’s Phase 1b program is fully enrolled, with 34 CHB patients now treated with VRON-0200, including a combination cohort with investigational antivirals; longer term clinical data from the full cohort is expected in Q4 2025 o VRON-0200 clinical data, presented earlier this year at APASL and EASL demonstrated: - VRON-0200 was safe and well tolerated, with no serious treatment-related adverse events (SAEs), treatment discontinuations, or treatment-related clinical laboratory abnormalities reported - HBsAg declines were observed in patients treated with an intramuscular (IM) injection of VRON-0200 even though VRON-0200 does NOT directly target S-antigen, suggesting a possible broadening, and restoration of anti-HBV immune responses - After a single VRON-0200 prime dose, rapid and profound HBsAg declines were observed in all evaluable patients 7 days after the first combination dose. These types of responses have not been previously reported, even with PEG-IFN containing regimens - These data suggest VRON-0200 could be the key backbone agent in future HBV functional cure regimens o The Phase 1b study is ongoing – these data, from all Cohorts, as well as the long-term followup and exploratory analyses, will further inform future treatment strategies to maximize functional cure rates and potentially expand patient populations o A global Phase 2b study (“SPARK-B”) for HBV Functional Cure is in development; in parallel, additional manufacturing activities to support late-stage development are ongoing o Virion is in partnership discussions to further accelerate development and maximize access to a potential functional cure for persons living with CHB worldwide “Despite a preventative HBV vaccine, CHB remains a widespread global problem affecting 254 million persons and contributing to 1.1 million deaths/year from liver related complications. On this World Hepatitis Day, Virion, along with its partners, are committed to finding a cure for CHB,” said Dr. Andrew D. Luber, CEO of Virion. Luber added, “It is exciting to see the VRON-0200 Phase 1b data support our “Spark and Fan” treatment model, with VRON-0200 “sparking” a new HBV-specific immune response, and then the “fanning” of this response with the addition of antivirals, which remove the virus and it’s immunosuppressive effects.” Dr. Sue Currie, Virion’s COO commented, “This “Spark and Fan” treatment strategy could potentially offer a simple and well tolerated solution for a wide range of future HBV functional cure regimens for patients worldwide. We are excited to continue our current VRON-0200 clinical development program, including the planning of our future SPARK-B Phase 2b clinical trial. On this World Hepatitis Day, we are aware of the burden of CHB, and the urgent unmet medical need to achieve a functional cure that is safe, convenient, effective, and accessible for persons worldwide. What makes VRON-0200 so promising, besides being the first new immune modulator to restore broad anti-HBV immunity since pegylated-interferon, is its ease of dosing (a single i.m. injection), and favorable safety and tolerability profile, all critical factors to future functional cure treatments for persons with CHB.” ABOUT CHRONIC HEPATITIS B Despite a preventative vaccine, cases of chronic hepatitis B (HBV) continue to rise, with an estimated 254 million persons infected worldwide and 1.1 million deaths per year from HBV-related liver complications. Chronic HBV remains a global health issue with a high unmet medical need since there is no cure available. The current standard of care requires lifelong antiviral therapy to maintain control of the virus. To learn more about hepatitis and World Hepatitis Day, visit: www.worldhepatitis.org ABOUT VRON-0200 VRON-0200 is a therapeutic immunotherapy, administered by intramuscular injection, designed with the goal of providing a functional cure for chronic HBV infection. While the virus itself stimulates HBV-specific CD8+ T cells, for those patients that can’t clear the initial infection, their T cells soon become exhausted, placing limits on their ability to proliferate and control the virus. An ongoing Phase 1b trial has shown VRON-0200 to be safe, well tolerated, immunogenic, and has anti-HBV activity in chronically HBV-infected patients on nucleos(t)ide therapy. More details of the study can be found at ClinicalTrials.gov (Identifier: NCT06070051). ABOUT VIRION THERAPEUTICS (VIRION) Virion Therapeutics, LLC is a clinical-stage company developing novel T cell-based immunotherapies to cure cancer and chronic infectious diseases that utilize proprietary genetically encoded checkpoint modifiers to enhance and broaden CD8+ T cell responses to a tumor or chronic infection. Virion has since developed a robust pipeline, including its lead VRON-0200 clinical program, and several additional IND-enabling programs, such as its VRON-0300 oncology program for advanced solid tumors, leveraging its proprietary platform technologies.
