Free doesn’t mean access when supplies are limited

Having a COVID-19 therapy approved through an emergency use authorization (EUA) is not the same as having access to it, even if it’s free. With one-third of the COVID-19 cases confirmed globally as of today and 28.5% of the deaths, the U.S. is getting 40% of the 1.5 million doses of remdesivir Gilead Sciences Inc. is donating worldwide. The federal government last week began doling out the 607,000 doses to the states, which are then charged with distributing them to the hospitals with the greatest need. But given the supply and manufacturing timeline for the first drug granted an EUA to treat severe COVID-19 cases, more than 300,000 eligible U.S. patients likely will not have access to the drug through the end of July, said Brian Abrahams, a senior analyst with RBC Capital Markets LLC.
