Description

Dr. David Fajgenbaum, MD, MBA, MSc, is a pioneering physician-scientist, tenured professor at the Perelman School of Medicine at the University of Pennsylvania, and bestselling author who transformed his personal battle with the rare, deadly Castleman disease into a global mission to accelerate cures for humanity's 12,000 known diseases.

A Georgetown University graduate with advanced degrees from Oxford and Wharton, he co-founded the Castleman Disease Collaborative Network (CDCN) and Every Cure, leveraging AI and drug repurposing to unlock hidden treatments, earning spots on TIME's 2025 TIME100 Health list and major media recognition for his "cure thyself" story. Through his book Chasing My Cure and speaking engagements, Fajgenbaum inspires hope, advocates for patient-driven research and policy changes to speed up cures for rare diseases affecting millions worldwide. #vigilanceelite #shawnryanshow Dr. David Fajgenbaum Links: Website - https://davidfajgenbaum.com X - https://x.com/DavidFajgenbaum IG - https://www.instagram.com/dfajgenbaum LI - https://www.linkedin.com/in/davidfajgenbaum/ Every Cure - https://everycure.org Castleman Disease Collaborative Network - https://cdcn.org TED talk - go.ted.com/davidfajgenbaum TED YT - https://youtu.be/sb34MfJjurc Chasing My Cure (Amazon) - https://www.amazon.com/Chasing-My-Cure-Doctors-Action/dp/1524799637 Shawn Ryan Show Sponsors: https://bunkr.life – USE CODE SRS Go to https://bunkr.life/SRS and use code “SRS” to get 25% off your family plan. https://americanfinancing.net/srs NMLS 182334, nmlsconsumeraccess.org.

Great interview, I am a person going through cancer currently and this gives me hope. I currently have stage 4 cancer and receiving palliative care. So they are telling me a cure is pretty much out of the question. I have realized that I need to keep up the fight and when god wants me I am ready. I can leave this world with a clean conscience as I have always tried to think of others besides myself, 30 year retired military veteran. God bless you for taking the time to do tis interview. Very Respectfully Lance

I lost my dad to Castlemans disease in 2001. Within 9 months he was gone. He was 61. I watched him die a slow and horrible death. This disease is extremely rare and seeing someone living with it…I have no words.

Just after the 47 minute mark of this, David mentions Kaila, a Sophomore in college to be a nurse. That is my stepdaughter. She has an amazing story just like his! David was a pivotal person in her surviving this disease, as she remains in remission. David, we can not say THANK YOU enough for saving Kaila! You are doing amazing work!

+1 on the concierge model. I've never had a doctor sit and talk to me for almost an hour about how I'm doing. It made an incredible difference in my outlook and wellbeing.
