In combining two synthetic antibodies , this drug manages to reduce the amount of virus present in the back of the nose and throat of patients who test positive for Covid-19.

The European medicines regulator claims to have concluded that REGN-COV2 can be used as a treatment in patients "who do not require supplemental oxygen and who do not present a high risk of progressing to a severe form of Covid-19 . "

REGN-COV2 is a combination of casirivimab and imdevimab, two monoclonal antibodies given to patients by infusion, the EMA said.

Manufactured in the laboratory, these synthetic antibodies mimic the action of antibodies naturally produced by the immune system in the event of infection.

Casirivimab and imdevimab, were designed to attack the S protein, which forms the tiny spikes on the surface of the virus, the EMA said. The antibody clings to these spikes, preventing it from attaching itself to the human cell to infect it.
