In the race to find effective COVID-19 treatments, scientists are setting up clinical trials that test multiple drugs simultaneously, in the hopes of quickly determining which ones work best.

One, sponsored by the University of Oxford, tested multiple treatments, including the antimalarial hydroxychloroquine, HIV protease inhibitors lopinavir and ritonavir, and steroid dexamethasone. The conclusion? Hydroxychloroquine and the protease inhibitors don’t work—but dexamethasone significantly reduces mortality among hospitalized patients. Many people credit this steroid for President Trump’s speedy recovery.
