The experimental antibody drug given to US President Donald Trump has been called one of the most promising approaches to preventing serious illness from a Covid-19 infection.

Its maker, Regeneron Pharmaceuticals, said the company agreed to supply a single dose, given through an intravenously, for Mr Trump at the request of his physician under “compassionate use” provisions.

This is when an experimental medicine is provided on a case-by-case emergency basis while studies continue.

The new drug is in late-stage testing and its safety and effectiveness are not yet known, and no treatment has yet proven able to prevent serious illness after a coronavirus infection.

Mr Trump was given the experimental drug at the White House on Friday before he was taken to Walter Reed National Military Medical Centre.

Several doctors who treat Covid-19, including Dr David Boulware at the University of Minnesota, had speculated that doctors might use the antibody drug, given that this approach has worked against other diseases in the past.

“They’re not going to just sit around and watch to see if he gets sick,” he said.

Antibodies are proteins the body makes when an infection occurs and vaccines trick the body into thinking there is an infection so it makes these antibodies.

But it can take weeks for them to form after natural infection or a vaccine.

The drugs aim to give that protection immediately, by supplying concentrated versions of one or two antibodies that worked best against the coronavirus in laboratory and animal tests.

Regeneron’s drug contains two antibodies to enhance chances that it will work and the company previously developed a successful Ebola treatment from an antibody combination.

Earlier this week, Regeneron said partial results from about 275 Covid-19 patients who were not sick enough to need hospital treatment suggested it might be cutting how long symptoms last.

However, the study has not been completed, the results were only announced in a company news release and have not been published or reviewed by other scientists.

Mr Trump’s physician, Dr Sean Conley, said late on Friday the president had also been given the antiviral drug remdesivir at the military hospital.

The Gilead Sciences drug has been shown to help some Covid-19 patients recover faster.

Earlier, Dr Conley said Mr Trump also was taking zinc, vitamin D, an antacid called famotidine, melatonin and aspirin.

None of those have been proven to be effective against Covid-19.

Mr Trump apparently is not receiving hydroxychloroquine, a drug he widely promoted that has been shown in many studies to be ineffective for preventing or treating Covid-19.
