About Vir Biotechnology

Vir Biotechnology, Inc. is a clinical-stage biopharmaceutical company focused on discovering and developing medicines for serious infectious diseases and cancer by harnessing the immune system. Its most advanced program targets chronic hepatitis delta (CHD), the most severe form of chronic viral hepatitis, using a combination regimen of elebsiran (an HBV-targeting siRNA licensed from Alnylam) and tobevibart (a broadly neutralizing monoclonal antibody targeting HBsAg). The company's ECLIPSE registrational program comprises three Phase 3 trials designed to support global regulatory filings. In oncology, Vir is developing a pipeline of PRO-XTEN dual-masked T-cell engagers (TCEs) designed to remain inactive until reaching the tumor microenvironment, including VIR-5500 (PSMA-targeted, for prostate cancer, partnered with Astellas), VIR-5818 (HER2-targeted), and VIR-5525 (EGFR-targeted). The company also maintains a preclinical portfolio of masked TCEs directed at clinically validated solid tumor targets and programs across infectious diseases. Updated
