Dr. David Fajgenbaum has a rare disease called Castleman's Disease which put him on his death bed 5 times as he was in medical school and earning his MBA. He repurposed a drug to treat himself and is now the world's leading researcher in Castleman's Disease. He is now helping other rare disease groups by training them to use his collaborative approach to research. He also just published a book called Chasing My Cure.
