VIR-7831 Description

VIR-7831 (GSK4182136) is a fully human anti-SARS-CoV-2 monoclonal antibody that was selected based on its potential to neutralize the virus in vitro, kill infected cells, provide a high barrier to resistance, and achieve high concentrations in the lungs (one of the major sites of infection).

The antibody binds to an epitope on SARS-CoV-2 that is shared with SARS-CoV-1 (also known as SARS), indicating that the epitope is highly conserved, which may make it more difficult for escape mutants to develop.

VIR-7832 has been engineered with the potential to enhance lung bioavailability, have an extended half-life, and function as a therapeutic and/or prophylactic T cell vaccine.

VIR Bio a clinical-stage immunology company focused on combining immunologic insights with cutting-edge technologies to treat and prevent serious infectious diseases.

VIR-7831 Indication

VIR-7831 is being evaluated for the early treatment of COVID-19, a disease caused by the SARS-CoV-2 virus in patients who are at high risk of hospitalization.
