How About A Covid Pill?

Vaccines are great and all, but molnupiravir, an antiviral drug in late-stage trials, could give doctors another major tool to end the pandemic—if, of course, it proves safe and effective

The story of what might become the next major breakthrough in Covid-19 treatment starts on a hotel hallway floor in January 2020, months before you were worried about the virus, weeks before you likely knew it existed. A scientist and a business executive were at a health-care conference in San Francisco, hatching a plan to get a promising drug out of academia and into research trials for regulatory approval. George Painter, president of the Emory Institute for Drug Development, and Wendy Holman, chief executive officer of Ridgeback Biotherapeutics, had met at the Handlery Union Square Hotel to discuss a compound Painter had started developing with funding from the National Institutes of Health. They got so enthusiastic about the possibilities that their meeting ran long and a group of lawyers kicked them out of their room. So they continued on the hall floor, hours after they’d started.

Painter and Holman weren’t talking about targeting Covid at the time. The disease and the coronavirus that causes it, SARSCoV-2, weren’t major concerns at the J.P. Morgan-run conference, where handshakes and cocktail parties with hundreds of guests were still the norm. Rather, Painter was hoping his drug, molnupiravir, could get more funding to speed up flu studies. Holman was eager to see if it worked on Ebola. That’s the thing about molnupiravir: Many scientists think it could be a broad-spectrum antiviral, effective against a range of threats.
