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.

A Novel Combination Therapeutic Strategy Aiming to Functional Cure for Chronic Hepatitis B Virus Infection (A)

Hepatitis B virus (HBV) infection is a major public health threat in China. At present, a functional cure, also known as clinical cure or sustained Hepatitis B surface antigen (HBsAg) loss, is recommended as the ideal endpoint of HBV treatment. However, HBsAg loss can be achieved in less than 10% of chronic hepatitis B (CHB) patients treated with current available antiviral drug interferonα (IFNα) or nucleos(t)ide analogues (NAs) monotherapy. With the support of the national major special funding for infectious diseases from "11th Five-Year Plan" to "13th Five-Year Plan", we have implemented a pioneer clinical study of sequential combination of IFNα therapy on NAs to treat NAs-treated CHB patients (ie. New Switch Study). This is the world's first clinical trial aiming to functional cure, which increased the rate of HBsAg loss to 15% in the overall population in our study, and to 30-50% among those with lower baseline HBsAg levels. How to further improve the HBsAg loss rate is an urgent issue for us. The key point of achieving functional cure is to reverse the HBV-specific T cell exhaustion and establish the long-term immune control against HBV infection. Programmed death-1(PD-1)/programmed death-ligand 1 (PD-L1) axis blockade has been demonstrated to reinvigorate exhausted CD8+ T cells, and would be a potential strategy to treat chronic HBV infection. In this study, a large multicenter prospective study will be performed to explore the safety and efficacy of a novel combination strategy involving immune checkpoint inhibitor (anti-PD-1/anti-PD-L1 antibody) and IFNα in CHB patients, observe the HBsAg loss rate in NA-treated CHB patients receiving this combination strategy, evaluate the potential of breaking immune tolerance by this strategy, and further assess its efficacy to further improve the clinical cure rate on the basis of New Switch Study. Based on New Switch Study, this study further attempts to reverse T cell exhaustion in CHB patients, explore a novel platform of combination therapy development for clinical cure, and ultimately increase the HBsAg loss rate to higher than 50% in overall patients. The implementation of the project is expected to reduce the burden of HBV infection in China and contribute to the goal of global elimination of hepatitis B and C by 2030 (WHO 2030).

Targeting ANKRD11 Reverses HBV-Specific CD8+ T Cell Dysfunction and Tolerance

Achieving a functional cure for chronic hepatitis B (CHB) is largely hindered by the irreversible functional exhaustion and immune tolerance of hepatitis B virus (HBV)-specific CD8 positive T (CD8+ T) cells. In investigators previous studies, an in vivo Clustered Regularly Interspaced Short Palindromic Repeat(CRISPR) screen identified ANKRD11 for the first time as an "epigenetic brake" on CD8+ T-cell effector function. Loss of ANKRD11 markedly enhanced the expansion, effector function, and viral clearance capacity of HBV-specific T cells. Based on these findings, investigators hypothesize that ANKRD11 regulates the epigenetic program of T-cell exhaustion by restricting the activity of AP-1 family transcription factors, and that targeting ANKRD11 can reverse T-cell dysfunction and overcome immune tolerance. This project will: (1) elucidate the epigenetic mechanisms by which ANKRD11 regulates T-cell exhaustion using conditional knockout mouse models and multi-omics approaches; (2) evaluate how ANKRD11 deficiency reshapes the differentiation trajectory and antiviral function of HBV-specific T cells in models of chronic HBV infection; and (3) develop a combinatorial gene-editing strategy integrating "release of the brake" with "stepping on the accelerator" to generate enhanced T Cell Receptor-T cell Therapy(TCR-T) cells and evaluate their efficacy and safety in humanized mouse models. The study is expected to define a novel mechanism by which ANKRD11 regulates T-cell exhaustion, establish an enhanced TCR-T therapeutic strategy, and provide a potential approach toward achieving a functional cure for chronic HBV infection.

Approximately 24 participants will be enrolled in Group 1 and randomized to Cohort 1a or Cohort 1b. Those assigned to Cohort 1a will receive a low dose prime therapeutic vaccination of vector AdC7 on Day 1, followed by a booster vaccination on Day 91 using vector AdC6. Those assigned to Cohort 1b will receive a low dose prime therapeutic vaccination of vector AdC6 on Day 1, and will not receive a booster vaccination. Group 2 will then enroll approximately 24 participants randomized to Cohort 2a or Cohort 2b. Those assigned to Cohort 2a will receive a high dose prime therapeutic vaccination of vector AdC7 on Day 1, followed by a booster vaccination on Day 91 using vector AdC6. Those assigned to Cohort 2b will receive a high dose prime therapeutic vaccination of vector AdC6 on Day 1, and will not receive a booster vaccination. Group 3 will enroll approximately 8 participants randomized into Cohort 3a or Cohort 3b. Cohort 3a will receive the high dose prime VRON-0200 vaccination of vector AdC7 on Day 1, followed by doses of VIR-2218 plus VIR-3434 on Days 28, 56, 84, 112, 140 and 168, and then a booster using a high dose VRON-0200 vaccination of vector AdC6 on Day 196. Cohort 3b will receive the same high dose prime VRON-0200 vaccination of vector AdC7 followed by 6 doses of VIR-2218 plus VIR-3434 at the same timepoints as Cohort 3a, but will not receive the booster dose on Day 196.
