Eve Bio's open repurposing platform

GLP-1 drugs like Ozempic and Mounjaro have transformed the treatment of obesity as well as diabetes, can help treat heart disease, kidney disease, sleep apnea, and maybe even Alzheimer’s. But they are far from the only medicine with more than one use. Aspirin, colchicine, minoxidil, and Viagra were all found to treat more conditions than expected, and about a third of drugs end up with a second approved use.

In this episode, Jacob and Saloni explore the idea of drug repurposing: taking a medicine made for one disease and finding it works against others. They trace how GLP-1 drugs emerged from an adorable Gila monster, why some drugs have multiple uses, why so many of those uses go untested, and how patents, competition, prizes, and platform trials shape whether we ever find them.

Hard Drugs is a podcast from Works in Progress about medical innovation presented by Saloni Dattani and Jacob Trefethen.
