Description:
The ongoing COVID-19 pandemic, caused by severe respiratory syndrome coronavirus 2 (SARS-CoV-2), has created an immense public health, social, and economic burden. Variants of concern continue to emerge that have increased transmissibility, pathogenicity, or both and that reduce the effectiveness of current therapeutics and vaccines. Thus, there is a great need for broadly protective therapeutics.
This technology relates to two monoclonal antibodies targeting the spike protein of SARS-CoV-2 that between the two have picomolar activity against wild-type SARS-CoV-2 and the Alpha, Beta, Delta, and Omicron variants of concern. Additionally, one of the antibodies recognizes a highly-conserved epitope of the spike protein. Treatment with either monoclonal antibody before or after challenge with SARS-CoV-2 reduced symptoms and viral load in nasal turbinate and lung tissue in the golden Syrian hamster model. This monoclonal antibody technology has great potential to treat SARS-CoV-2 infections and may provide protection against future variants of concern.
This technology is available for licensing for commercial development in accordance with 35 U.S.C. 209 and 37 CFR part 404.
