New antiviral drugs are startlingly effective against the coronavirus--if they're taken in time. By Dhruv Khullar November 21, 2021 * * * * * Save this story for later.

In March, 2020, researchers at Emory University published a paper about a molecule called NHC/EIDD-2801. At the time, there were no treatments available for the coronavirus. But NHC/EIDD-2801, the researchers wrote, possessed "potency against multiple coronaviruses," and could become "an effective antiviral against SARS-CoV-2." A few days later, Emory licensed the molecule to Ridgeback Biotherapeutics, a Miami-based biotechnology company which had previously developed a monoclonal antibody for Ebola. Ridgeback partnered with the pharmaceutical giant Merck to accelerate its development. The Emory researchers named their drug molnupiravir, after Mjolnir--the hammer of Thor. It turns out that this was not hyperbole. Last month, Merck and Ridgeback announced that molnupiravir could reduce by half the chances that a person infected by the coronavirus would need to be hospitalized. The drug was so overwhelmingly effective that an independent committee asked the researchers to stop their Phase III trial early--it would have been unethical to continue giving participants placebos. None of the nearly four hundred patients who received molnupiravir in the trial went on to die, and the drug had no major side effects. On November 4th, the U.K. became the first country to approve molnupiravir; many observers expect that an emergency-use authorization will come from the U.S. Food and Drug Administration in December.
