Union-FAST: An Intelligent-Agent Intervention to Increase Antiviral Treatment Uptake in Diagnosed-but-Untreated Hepatitis B Patients

The World Health Organization (WHO) has set a target to eliminate viral hepatitis by 2030, aiming for a 90% diagnosis rate and an 80% treatment rate for chronic hepatitis B (CHB). However, as of 2024, only 26.1% of CHB infections globally have been diagnosed, and only 14.6% have received treatment, with treatment coverage falling far short of the target. A large number of patients are in a "Diagnosed-but-Untreated (DBU)" state, with major barriers including: low disease awareness, concerns about medication side effects, fragmented healthcare pathways, and poor physician-patient communication. Traditional hospital-based follow-up models are constrained by human resources and the capacity for health information system integration, making them difficult to scale widely in primary care settings. Supported by the National Key R\&D Program of China, our team has successfully developed the world's first infectious disease agent (Union-Agent) after more than two years of research. This study aims to conduct a multicenter, prospective, two-cohort observational and interventional investigation to identify the reasons why DBU patients fail to initiate treatment and to explore whether an intervention using the Union-Agent can significantly increase the rate of antiviral treatment initiation within six months among DBU patients who meet the antiviral indications according to the 2022 Chinese guidelines for the prevention and treatment of chronic hepatitis B. The study hypothesizes that, compared to baseline, the Union-Agent can enable 50%-60% of treatment-eligible DBU patients to initiate antiviral therapy within six months.

Hospital-Based Management of Patients With Chronic Hepatitis B Virus Infection

Since 2022, the Third Affiliated Hospital of Sun Yat-sen University has initiated the "Hot Wave Project", a comprehensive hepatitis B infection prevention and management system encompassing patient education, screening, referral, treatment, and follow-up. In 2024, this system was expanded to the Sixth Affiliated Hospital and the Fifth Affiliated Hospital of Sun Yat-sen University, transitioning into a multicenter, hospital-based cohort study on hepatitis B management.The primary objective of this study is to increase the referral rate of HBsAg-positive patients in non-hepatology/non-infectious disease departments to 50%. The secondary objective is to improve the treatment rate of hepatitis B infected patients in non-hepatology/non-infectious disease departments, particularly focusing on the diagnosed but untreated (DBU) population. Furthermore, this study aims to analyze the cost-effectiveness and clinical benefits of in-hospital hepatitis B screening and management strategies.In 2025, a Patient-Reported Outcomes (PRO) sub-study was added to the project to evaluate the impact of antiviral therapy on the Health-Related Quality of Life among a cohort of treatment-naïve patients with chronic hepatitis B.

VIR-2218 and Peginterferon Alfa-2a for Chronic Hepatitis B

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.

Strengthening Hepatitis B Screening, Linkage to Care and Long-Term Monitoring in Phichit Province, Thailand: A Birth Bohort Approach

This study in Phichit province, Thailand, aims to find and support adults born before 1992 who are at high risk for hepatitis B infection. Many people in this group were born before the universal hepatitis B vaccine was available and may not know they are infected. The study will invite nearly 240,000 eligible adults for free hepatitis B screening. Those who test positive will be linked to care at one of 12 district hospitals. Doctors will use simplified 2024 World Health Organization (WHO) guidelines to decide who needs treatment. Eligible individuals will receive a safe, effective daily medicine (tenofovir alafenamide). The study will use community health volunteers and phone reminders to help patients stay in care and take their medication regularly. Over three years, the study will track improvements in liver health and virus levels, aiming to prevent liver cirrhosis and cancer.
