AI-Guided Alzheimer's Trial Design Lessons

This episode explores the challenges of Alzheimer's disease treatment and how artificial intelligence is being used to improve trial design and patient outcomes. The discussion covers recent trials, including donanumab and semaglutide, and the importance of mechanistic precision and biomarker-guided stratification. The role of AI in rescuing failed drugs and optimizing trial logistics is also examined.
