SAN FRANCISCO, Oct. 15, 2021 (GLOBE NEWSWIRE) -- Vir Biotechnology, Inc. (Nasdaq: VIR) today announced that three abstracts highlighting data from its hepatitis B clinical program and one health outcomes research abstract have been accepted for oral and poster presentation at the American Association for the Study of Liver Diseases (AASLD) The Liver Meeting®, taking place virtually from November 12-15, 2021.
Among the accepted abstracts is an oral presentation of new data from a Phase 2 study evaluating VIR-2218, an investigational small interfering ribonucleic acid (siRNA) that mediates RNA interference (RNAi), alone and in combination with pegylated interferon alfa-2a (PEG-IFNα), an approved immunomodulator for the treatment of chronic hepatitis B virus (HBV), for the potential functional cure of chronic HBV infection.
Additionally, two poster presentations will highlight pre-clinical and clinical data for VIR-3434, an investigational HBV-neutralizing monoclonal antibody designed to inhibit HBV entry into cells, reduce the number of virion and subvirion particles in the blood, and potentially function as a therapeutic T cell vaccine. A third poster presentation will focus on the impact of chronic HBV and its treatments on patients’ lives, as well as the perceived value of a functional cure.
Presentation details are as follows:

About VIR-2218
VIR-2218 is an investigational subcutaneously administered HBV-targeting siRNA that has the potential to stimulate an effective immune response and have direct antiviral activity against HBV. It is the first siRNA in the clinic to include Enhanced Stabilization Chemistry Plus (ESC+) technology to enhance stability and minimize off-target activity, which potentially can result in an increased therapeutic index. VIR-2218 is the first asset in the company’s collaboration with Alnylam Pharmaceuticals, Inc. to enter clinical trial.
About VIR-3434
VIR-3434 is an investigational subcutaneously administered HBV-neutralizing monoclonal antibody designed to block entry of all 10 genotypes of HBV into hepatocytes and reduce the level of virions and subviral particles in the blood. VIR-3434, which has been Fc engineered to potentially function as a T cell vaccine against HBV in infected patients, also incorporates Xencor’s Xtend™ in order to have an extended half-life.
About Vir Biotechnology
