This week, we’re joined by Huseyin Naci to discuss the recent press release from Eisai and Biogen announcing the Phase III trial results for lecanemab for use in Alzheimer’s disease, and the FDA’s decision to accept the drug onto its accelerated approval pathway. We talk about the pros and cons of using surrogate endpoints to predict clinical outcomes. How can we strike a better balance in clinical trials between generating high-quality and trustworthy evidence, and the urgent needs of patients with life-limiting conditions and very few available treatment options? Our guest: Huseyin Naci is an associate professor of Health Policy at the London School of Economics and Political Science (LSE). He is also an advisor to the Analysis section of The BMJ.
