The experimental antibody drug given to 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 Inc., said the company agreed to supply a single dose, given through an IV, for Trump at the request of his physician under “compassionate use” provisions, when an experimental medicine is provided on a case-by-case emergency basis, while studies of it continue.
The new drug is in late-stage testing and its safety and effectiveness are not yet known. No treatment has yet proved able to prevent serious illness after a coronavirus infection.
Trump was given the experimental drug at the White House on Friday before he was taken to Walter Reed National Military Medical Center, where he’ll be monitored, officials said. So far, Trump has had only mild symptoms, including fatigue.
