Synopsis:
What happens when a world-class scientist and a philanthropic legacy collide with one of medicine’s greatest challenges? Dr. Howard Fillit and Mark Roithmayr of the Alzheimer’s Drug Discovery Foundation (ADDF) join host Alok Tayi for an inspiring conversation on bold science, visionary funding models, and the future of Alzheimer’s research. From treating Estée Lauder in the 1990s to building a $100M venture philanthropy engine, they trace ADDF’s evolution into a global leader in high-risk, high-reward drug development. The discussion covers the rise of biomarkers and digital diagnostics, the foundation’s partnerships with visionaries like Bill Gates and Jeff Bezos, and how ADDF’s venture philanthropy approach bridges the “valley of death” in biotech. They also dive into global regulatory challenges, the economic urgency of Alzheimer’s, and why the future lies in prevention, precision medicine, and a patient-first mindset. This episode is a masterclass in scientific grit, ecosystem thinking, and turning urgency into progress.
