Americans will have access to additional drug against Covid-19. And it’s not just any: it had been used to heal no less than President Donald Trump. The American Medicines Agency (FDA) thus granted emergency authorization on Saturday for treatment with synthetic antibodies from the company Regeneron.

This change comes after administration of REGEN-COV2, a combination of two laboratory-made antibodies, has been shown to reduce coronavirus-related hospitalizations or emergency room visits in patients with secondary illnesses or ‘comorbidities’. . “Allowing these monoclonal antibody therapies could allow patients to avoid hospitalization and ease the burden on our health care system,” said FDA official Stephen Hahn.

Effective mainly in the initial phase

Regeneron President Leonard Schleifer assured that this decision was “an important step in the fight against Covid-19, because high-risk patients in the United States will have access to promising therapy at the start of their infection.” These antibodies mimic what the immune system does after infection, blocking the tip of the virus that allows it to attach to and enter human cells. It is considered to be most effective during the initial phase of infection, when the antibodies still have a chance to control the invader, and not during the second phase of Covid-19.

The Regeneron treatment is the second synthetic antibody treatment to receive “emergency use clearance” from the FDA. A similar therapy developed by the American company Eli Lilly had already obtained this status on November 9. In addition, Regeneron has received more than $ 450 million from the US government for its efforts to develop drugs against Covid-19.
