Vir Biotechnology and GSK Announce NHS-Supported AGILE Study to Evaluate VIR-7832 in the Early Treatment of COVID-19
- Second monoclonal antibody from Vir-GSK collaboration to be investigated as a potential COVID-19 treatment
- Preclinical data suggest VIR-7832 has two distinguishing properties: enhanced ability to clear infected cells and potential to enhance virus-specific T cell function, which could help treat and/or prevent COVID-19 infection
- Trial targeted to begin in 1Q:2021 at multiple sites across the
The AGILE trial platform, which will be the first to test VIR-7832 in humans, uses adaptable protocols and statistical models to enable the evaluation of candidate medicines for COVID-19 treatment. The initiative is a collaboration between the
VIR-7832 is set to become the second monoclonal antibody from the Vir-GSK collaboration to be investigated as a potential COVID-19 treatment. The first antibody, VIR-7831, is currently being investigated in two global phase 3 studies; for the early treatment of COVID-19 in patients who are at high risk of hospitalization, and for the treatment of hospitalized patients with COVID-19.
Phase 1b/2a AGILE Study Design
AGILE is a randomized, controlled, multi-center, seamless, adaptive Phase 1b/2a platform for the rapid evaluation of candidates of COVID-19 treatment in hospitalized patients and also in the community with early disease. The AGILE platform will assess VIR-7832 and VIR-7831 in adult outpatients with mild to moderate COVID-19 infection. The dose-escalation Phase 1b part of the study will evaluate the safety and tolerability of a single dose of VIR-7832 given by intravenous (IV) infusion and determine the dose for evaluation in the Phase 2a part of the study. A total of 24 study participants will be randomized 3:1 to VIR-7832 or placebo. The Phase 2 part of the study will include three treatment arms: 50 patients randomized to VIR-7832, 50 patients to VIR-7831, and 25 patients to placebo. The co-primary endpoints are safety and virologic activity of VIR-7832 as assessed by a change in SARS-CoV-2 viral load from baseline to Day 8. The Phase 2 part of the study also will assess the T cell responses to SARS-CoV-2 of VIR-7832 and VIR-7831. The trial is being conducted at up to five sites in the
About VIR-7832 / GSK4182137
VIR-7832 is a dual-action monoclonal antibody. Preclinical data suggest it has the potential to both block viral entry into healthy cells and an enhanced ability to clear infected cells. The antibody binds to an epitope on SARS-CoV-2 that is shared with SARS-CoV-1 (the virus which causes SARS), indicating that the epitope is highly conserved, which may make it more difficult for resistance to develop. VIR-7832 also has been designed to achieve high concentration in the lungs to ensure optimal penetration into airway tissues affected by SARS-CoV-2 and to have an extended half-life. Importantly, VIR-7832 has been engineered to potentially enhance virus-specific T cell function, which could help treat and/or prevent COVID-19 infection.

These forward-looking statements are based on Vir’s expectations and assumptions as of the date of this press release. Forward-looking statements contained in this press release include, but are not limited to, statements regarding the potential benefits of VIR-7832 and VIR-7831 in the treatment of COVID-19, the potential benefits of participating in the AGILE study, and statements around the expected timing of the Phase 1b/2a clinical trial. Many factors may cause differences between current expectations and actual results, including delays or failures in planned patient enrollment or retention, clinical site activation rates or clinical trial enrollment rates that are lower than expected, unexpected safety or efficacy data observed during preclinical or clinical studies, challenges in the treatment of hospitalized patients, difficulties in collaborating with other companies or government agencies, challenges in accessing manufacturing capacity, successful development and/or commercialization of alternative product candidates by our competitors, changes in expected or existing competition, delays in or disruptions to our business or clinical trials due to the COVID-19 pandemic, geopolitical changes or other external factors, and unexpected litigation or other disputes.
GSK Cautionary Statement Regarding Forward-Looking Statements
