Trump treated with experimental drug for COVID-19

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. 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. Its maker, Regeneron Pharmaceuticals Inc., said the company agreed to supply a single dose, 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.
