146: Overviewing Donanemab’s New Dosing Regimen: Lowering ARIA Risk in Alzheimer Care

Welcome to the NeurologyLive® Mind Moments® podcast. Tune in to hear leaders in neurology sound off on topics that impact your clinical practice.In this episode, "Donanemab’s New Dosing Regimen: Lowering ARIA Risk in Alzheimer’s Care" John Sims, MD, head of medical development for donanemab at Eli Lilly and Company, joins NeurologyLive to discuss the recently updated label for donanemab (Kisulna), an anti-amyloid Alzheimer disease (AD) therapy. Sims breaks down the key safety data from the TRAILBLAZER-ALZ-6 study (NCT05738486) that led to a newly approved titration-based dosing regimen aimed at minimizing ARIA risk. He outlines considerations for clinicians treating patients with early-stage AD, including genotype-based stratification, ARIA severity patterns, and implications for prescribing and patient counseling. Furthermore, Sims also shares takeaways about donanemab’s clinical impact and how the results may shape the future of anti-amyloid therapy development and AD care.Looking for more dementia and Alzheimer disease discussion?
