Vir Biotechnology Announces New Research Demonstrating Novel Mechanisms by Which SARS-CoV-2 Enters Host Cells
– Growing body of evidence suggests monoclonal antibodies that target a conserved epitope have the potential to be highly effective against SARS-CoV-2 and associated known mutations – – Newly identified cell surface proteins play a role in SARS-CoV-2 infection and determine how certain classes of antibodies work – SAN FRANCISCO, April 08, 2021 (GLOBE NEWSWIRE) -- Vir Biotechnology, Inc. (Nasdaq: VIR) today announced the publication of new preclinical research highlighting novel mechanisms by which SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus-2) enters host cells and identifying how auxiliary receptors may impact the clinical efficacy of monoclonal antibodies (mAbs). The research highlights the distinct mechanism of action of non-receptor-binding motif (RBM)-targeting antibodies, such as VIR-7831 and VIR-7832, the Company’s investigational SARS-CoV-2 mAbs that target a conserved non-RBM site within the receptor binding domain (RBD). While prior literature has shown that SARS-CoV-2 infection is mediated by the virus binding to the ACE-2 entry receptor, findings from this research, posted on BioRxiv, highlight the importance of three additional auxiliary receptors that enhance infection mediated by the ACE-2 receptor. This new study addresses the role of DC-SIGN and L-SIGN lectins in infection and further identifies the SIGLEC1 lectin as a new participant in infection. SIGLEC1 is of particular importance because it is highly expressed and associated with SARS-CoV-2 in macrophages – an inflammatory cell type that is prominent in the lungs of patients with severe COVID-19. These cells can bind to infectious SARS-CoV-2 and present the virus to another cell to establish infection in that second cell. These auxiliary receptors also play an important role in modulating the neutralizing activity of different classes of spike-specific antibodies and may contribute to viral dissemination in the most severe COVID-19 cases. This study addresses another important aspect related to the influence of the experimental methods used in measuring the neutralizing activity of different classes of spike-specific antibodies. Cells that overexpress ACE-2 at levels in excess of normal cells are widely used in neutralization assays because they can be infected with high efficiency. While these cell lines effectively measure the neutralizing activity of antibodies that target the RBM of the SARS-CoV-2 spike protein, they inadequately measure the neutralizing activity of non-RBM antibodies, as well as antibodies that target the N-terminal domain (NTD) of the spike. The NTD is a major target of human immunity to SARS-CoV-2. This observation indicates the significant limitations of the use of cells overexpressing ACE-2 for studies of mAbs and measuring serum neutralizing antibodies elicited by vaccination or infection. When tested in more physiologic conditions, with cells expressing low levels of ACE-2 together with lectin receptors, non-RBM antibodies showed an enhanced ability to block viral infection. S309 (the precursor to VIR-7831 and VIR-7832), which targets a conserved non-RBM site within the RBD, showed enhanced neutralizing activity, reaching 100% neutralization. In contrast, antibodies that target the RBM were less effective in preventing infection. Additionally, a subset of the RBM-targeting antibodies analyzed in the study, including three clinical-stage antibodies, were shown to promote cell-cell fusion driven by the SARS-CoV-2 spike protein, potentially promoting cell-to-cell spread of the infection. “As we continue to advance research that elucidates the mechanisms of SARS-CoV-2 infection, including the development of the disease and immunity to infection, one consistent finding of this study appears to be that certain classes of mAbs have potential advantages at blocking auxiliary receptor-enhanced infection,” said Herbert “Skip” Virgin, M.D., Ph.D., chief scientific officer of Vir. “These data, together with recent studies showing an 85% reduction in hospitalization and death in high-risk outpatients receiving VIR-7831 compared to placebo and promising performance against SARS-CoV-2 variants in the lab, add to the growing body of evidence suggesting that antibodies that bind to a conserved non-RBM site of the virus are well suited to help treat and/or prevent COVID-19 infection and have the potential to address both current and future mutations.” VIR-7831 and VIR-7832 are investigational compounds, not approved by the U.S. Food and Drug Administration or any other regulatory authority. About VIR-7831VIR-7831 is an investigational dual-action SARS-CoV-2 monoclonal antibody. Preclinical data suggest it has the potential to both block viral entry into healthy cells and clear infected cells. The antibody binds to an epitope on SARS-CoV-2 that is shared with SARS-CoV-1 (the virus that causes SARS), indicating that the epitope is highly conserved, which may make it more difficult for resistance to develop. VIR-7831, which incorporates Xencor’s Xtend™ technology, 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. About VIR-7832 VIR-7832 is an investigational dual-action SARS-CoV-2 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 that causes SARS), indicating that the epitope is highly conserved, which may make it more difficult for resistance to develop. VIR-7832, which incorporates Xencor’s Xtend and other Fc technologies, 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 also has been engineered to potentially enhance virus-specific T cell function, which could help treat and/or prevent COVID-19 infection.

Vir Biotech's VIR-7831 Maintains Activity Against California Variant Of COVID-19 Infection
Vir Biotechnology Inc (NASDAQ: VIR) has announced new preclinical data of VIR-7831, the company's investigational monoclonal antibody (mAb) against SARS-CoV-2. The new data showed that the antibody maintains its neutralizing activity against a mutation in the receptor-binding domain (RBD) of SARS-CoV-2, called L452R, found in the California variant (B.1.427/B.1.429). Data from 43 vaccinated donors and nine convalescent donors demonstrated that the S13I, W152C, and L452R mutations reduced the neutralization potency of plasma three to sixfold. Besides, the L452R mutation reduced the neutralization activity of 14 out of 35 RBD-specific mAbs, including three clinical-stage antibodies. Complete loss of neutralization by all 10 N-terminal domain-specific mAbs mediated by an unconventional escape mechanism was observed. VIR-7831, which targets a non-receptor binding motif (RBM) epitope, was unaffected by the L452R mutation. VIR-7831 is an investigational dual-action SARS-CoV-2 monoclonal antibody. Recently, VIR-7831 co-administered with GlaxoSmithKline plc's (NYSE: GSK) bamlanivimab, demonstrated a 70% relative reduction in persistently high viral load at day seven compared to placebo in low-risk COVID-19 patients. Price Action: VIR shares are up 0.04% at $51.29 in premarket on the last check Monday.
