Study Finds Dual-Antibody Drugs Effective Against COVID-19, says an article on Reuters.
- two types of antibodies effective against a wide range of variants of the coronavirus
- three of the four variants that have been designated “variants of concern” by WHO
Antibodies effective against Covid-19
COVID-19 therapies made from a cocktail of two types of antibodies were effective against a wide range of variants of the coronavirus in mice and hamster study, the Washington University School of Medicine in St. Louis reported on Monday.
Antibodies are used to treat cases of COVID-19, often early in the process. Former U.S. President Donald Trump was treated by an antibody cocktail by Regeneron Pharmaceuticals (REGN.O) in October after he tested positive for COVID-19.
Variants of concern
The latest study included three of the four variants that have been designated “variants of concern” by the World Health Organization, including Alpha, first identified in the UK, Beta, first found in South Africa and Gamma found in Brazil, as well as an emerging variant from India similar to the Delta variant of concern.
The U.S. Food and Drug Administration in April revoked the emergency use authorization of Eli Lilly’s (LLY.N) single antibody therapy, bamlanivimab, saying there was an increased circulation of variants resistant to the therapy when used alone.
