An international team led by University of British Columbia researcher Dr. Josef Penninger has found a trial drug that effectively blocks the cellular door SARS-CoV-2 uses to infect its hosts.
The findings, published today in Cell, hold promise as a treatment capable of stopping early infection of the novel coronavirus that, as of April 2, has affected more than 981,000 people and claimed the lives of 50,000 people worldwide.
The study provides new insights into key aspects of SARS-CoV-2, the virus that causes COVID-19, and its interactions on a cellular level, as well as how the virus can infect blood vessels and kidneys.
“We are hopeful our results have implications for the development of a novel drug for the treatment of this unprecedented pandemic,” says Penninger, professor in UBC’s faculty of medicine, director of the Life Sciences Institute and the Canada 150 Research Chair in Functional Genetics at UBC.
“This work stems from an amazing collaboration among academic researchers and companies, including Dr. Ryan Conder’s gastrointestinal group at STEMCELL Technologies in Vancouver, Nuria Montserrat in Spain, Drs. Haibo Zhang and Art Slutsky from Toronto and especially Ali Mirazimi’s infectious biology team in Sweden, who have been working tirelessly day and night for weeks to better understand the pathology of this disease and to provide breakthrough therapeutic options.”
