COVID-19 Antibodies: Regenron Pharmaceuticals And Researchers From University Of Maryland Identify New Potent Antibody Cocktail

COVID-19 Antibodies: Medical researchers from the University of Maryland School of Medicine (UMSOM) in collaboration with scientists from Regeneron Pharmaceutcials have evaluated several human antibodies to determine the most potent combination to be mixed in a cocktail and used as a promising anti-viral therapy against the virus that causes COVID-19.


 
The research demonstrates the rapid process of isolating, testing and mass-producing antibody therapies against any infectious disease by using both genetically engineered mice and plasma from recovered COVID-19 patients.
 
The research findings were published in the journal Science. https://science.sciencemag.org/content/early/2020/06/15/science.abd0827
 
The identified antibody cocktail evaluated by UMSOM researchers will be used to treat COVID-19 patients in a clinical trial that was launched last week. The study was funded by Regeneron, a biotechnology company based in Tarrytown, New York.
 
Typically antibodies are proteins the immune system naturally makes in response to foreign invaders like viruses and bacteria. Antibody therapies were first tried in the late 19th century when researchers used a serum derived from the blood of infected animals to treat diphtheria.
 
In order to produce the so-called monoclonal antibodies for an antibody cocktail to fight COVID-19, the researchers first needed to identify which antibodies fight the novel coronavirus most effectively.
 
The process involved determining which antibodies could bind most effectively to the spike protein found on the surface of SARS-CoV-2, the virus that causes COVID-19.
 
The study team from Regeneron evaluated thousands of human antibodies from plasma donations from recovered COVID-19 patients. They also generated antibodies from mice genetically engineered to produce human antibodies when infected with the virus.
 
Research co-author Dr Matthew Frieman, Ph.D., Associate Professor of Microbiology and Immunology at the University of Maryland School of Medicine told Thailand Medical News, "The ability of the research team to rapidly derive antibodies using these two methods enabled us screen their selected antibodies against live virus to determine which had the strongest anti-viral effects."
 
Dr Frieman has been studying coronaviruses for the past 16 years and has been carefully studying SARS-CoV-2 in his secure laboratory since February.
 
He and his UMSOM colleagues evaluated four of the most potent antibodies for to determine the potential of each one to neutralize the SARS-CoV-2 virus. They identified the two that would form the most powerful mix when used in combination.
 
Co-author Dr Stuart Weston, Ph.D., a post-doctoral research fellow in the Department of Microbiology and Immunology added, "An important goal of this research was to evaluate the most potent antibodies that bind to different molecules in the spike protein so they could be mixed together as a treatment.”
 
The new cocktail containing the two antibodies is now being tested in a new c linical trial sponsored by Regeneron that will investigate whether the therapy can improve the outcomes of COVID-19 patients (both those who are hospitalized and those who are not). It will also be tested as a preventive therapy in those who are healthy but at high risk of getting sick because they work in a healthcare setting or have been exposed to an infected person.
 
Dr Dean E. Albert Reece, MD, Ph.D., MBA, who is also Executive Vice President for Medical Affairs, UM Baltimore, and the John Z. and Akiko K. Bowers Distinguished Professor, University of Maryland School of Medicine further added, "Our School of Medicine researchers continue to provide vital advances on all fronts to help fight the COVID-19 pandemic and ultimately save lives. This particular research not only contributes to a potential new therapy against COVID-19 but could have broader implications in terms of the development of monoclonal antibody therapies for other diseases."
 
The clinical trial involving the new antibody cocktail is currently underway and Thailand Medical News will provide progress updates of that trial.
