The Food and Drug Administration on Saturday, Nov. 21, 2020 authorized the use of the Regeneron Pharmaceuticals Inc. drug to try to prevent patients with mild-to-moderate disease from worsening and needing hospitalization. It's given as a one-time treatment through an IV and is still going through more testing to establish its safety and effectiveness. Antibodies are proteins the body makes to target and help eliminate viruses, but it can take weeks for the best ones to form after an infection occurs.
U.S. health officials Saturday agreed to allow emergency use of a second antibody drug to help the immune system fight COVID-19, an experimental medicine that President Donald Trump was given when he was sickened last month. There’s no way to know whether the Regeneron drug helped Trump recover; he received a host of treatments and most COVID-19 patients recover on their own.
The drug is given as a one-time treatment through an IV. The FDA allowed its use in adults and children 12 and over who weigh at least 88 pounds (40 kilograms) and who are at high risk of severe illness from COVID-19 because of age or certain other medical conditions.
Regeneron said that initial doses will be made available to roughly 300,000 patients through a federal government allocation program. Those patients will not be charged for the drug but may have to pay part of the cost of giving the IV. source
