David Fajgenbaum is on a mission to repurpose drugs for the 9,000 diseases with no approved treatments. Fajgenbaum's journey started as a patient with idiopathic multicentric Castleman disease, an illness that he nearly succumbed to five times and for which he found a treatment. In September 2022, Fajgenbaum cofounded the Every Cure Foundation, a nonprofit organization that identifies and tests generic medicines for novel indications.
