The US Food and Drug Administration (FDA) has granted emergency authorization to the experimental antibody drug made by Regeneron Pharmaceuticals to treat Covid-19.
US President Donald Trump had been administered the particular antibody-drug after he tested positive for the novel coronavirus in October.
The drug reportedly imitates the body's natural defenses instead of waiting for the body to develop its antibodies.
Regeneron's drug is a combination of two monoclonal antibodies, called casirivimab and imdevimab.
Patients with co-morbid conditions, who were administered the drug showed reduced signs of developing severe complications together with reduced Covid-19 related hospitalizations and emergency medical visits.
