Cell surface vimentin is thought to be a potential target for the treatment of coronavirus infections.

Novacyt Group, of Paris, is collaborating with Astrazeneca plc, of Cambridge, U.K., and the University of Cambridge to support the U.K. government’s plan to increase testing for COVID-19. A new laboratory will be set up by Astrazeneca and London-based Glaxosmithkline plc and the university’s Anne McLaren laboratory to be used for high-throughput screening for COVID-19 testing and to explore the use of alternative chemical reagents for test kits in order to help overcome current supply shortages.

Ossianix Inc., of Philadelphia, said it is developing therapeutic single-domain VNAR antibodies to the COVID-19 spike protein. According to the company, single-domain VNAR antibodies have large CDR3 binding domains that preferentially bind cavities and buried epitopes in proteins, which are often the sites of protein-protein interactions, making it likely that screening of multi-isoform VNAR libraries built on a non-immunogenic scaffold will identify hits that will be different from those isolated from human B cells or other immunization approaches. Once identified, VNAR single domain antibodies that block the viral entry can then be developed using the well-established pathway for conventional antibodies, Ossianix said. In addition, the company said it has identified and patented VNAR antibodies that bind to the human transferrin receptor and have the capability to specifically target the lung in rodents and nonhuman primates. Those VNARs can be fused to antibodies or other therapeutics creating bispecific biologics for targeted delivery to the lung, which is a major site of infectivity.

Oxford Biomedica plc, of Oxford, U.K., said it joined a consortium led by the Jenner Institute, Oxford University, to rapidly develop, scale up and manufacture a potential vaccine candidate for COVID-19, called ChAdOx1 nCov-19.
