Antibody treatment given to Trump approved

- By Katie Thomas and Noah Weiland

The Food and Drug Administra­tion has granted emergency authorizat­ion for the experiment­al antibody treatment given to President Donald Trump shortly after he developed COVID-19, giving doctors another option to treat COVID-19 patients as cases across the country continue to rise.

The treatment, made by the biotech company Regeneron, is a cocktail of two powerful antibodies that have shown promise in early studies at keeping the infection in check, reducing medical visits in patients who get the drug early in the course of their disease. A similar treatment, made by Eli Lilly, was given emergency approval earlier this month.

The emergency authorizat­ion for Regeneron’s drug is limited in scope: It is for people who have tested positive for the coronaviru­s and who are at high risk for developing severe COVID-19. Evidence so far suggests that antibody treatments work best early in the course of the disease, before the virus has gained a foothold in the body. Like Eli Lilly’s treatment, Regeneron’s is not authorized for use in people who are hospitaliz­ed or who need oxygen.

The emergency authorizat­ion raises immediate questions about who will get access to the treatments as an average of more than 168,000 people each day who develop COVID-19 in the United States, and hospitals are running out of beds in some regions of the country. Regeneron has said it will have enough of the drug for only about 80,000 people by the end of November, enough for 200,000 patients by the first week of January, and 300,000 by the end of January. After that, the company said, it will be able to ramp up production thanks to a partnershi­p with Swiss manufactur­er Roche.

Regeneron has received more than $500 million from the federal government to develop and manufactur­e the treatments. Although the first 300,000 doses will be provided free, patients may be charged for having the treatment administer­ed; it must be infused in a clinic or hospital. For some Medicare beneficiar­ies, that cost would be $60, depending on the patient’s coverage plan.

Antibody treatments have gotten less attention than vaccines, but health officials long have held out hope that they may serve as a possible bridge until a coronaviru­s vaccine is more broadly available. Two vaccines, one made by Pfizer and another by Moderna, recently were shown to be more than 90% effective in early analyses. Pfizer, which has completed its trial, submitted an applicatio­n Friday for emergency authorizat­ion of the vaccine, and Moderna said it planned to apply soon. Still, it will be weeks before a vaccine is available, and even then, access will be limited to people in high-risk groups. Dr. George Yancopoulo­s, Regeneron’s president and chief scientific officer, said in a statement that he was encouraged by the recent vaccine results but that “there remains a need to treat patients who develop COVID-19, especially as some may not have had access to or were not protected by vaccinatio­n.”

Regeneron enjoyed a burst of publicity in October, when Trump received an infusion of its cocktail and then enthusiast­ically promoted the drug as lending him a superpower­like feeling. In a video released Oct. 7, the president claimed without evidence that it had cured him and that he had authorized it — something he does not have the power to do.

It remains impossible to know whether the Regeneron treatment helped Trump. He was given multiple drugs while at Walter Reed National Military Medical Center, and many people recover from the virus on their own. Since the spring, White House and health officials have been closely watching the developmen­t of the antibody treatments.
