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, we spoke with Marwan Sabbagh, MD, FAAN, a behavioral neurologist at the Barrow Neurological Institute. He joined the show to discuss the clinical trial results for lecanemab that were presented at the Clinical Trials on Alzheimer’s Disease meeting in San Francisco, the drug’s overall efficacy profile, as well safety information and the rates of ARIA, and more. Lecanemab (Biogen/Eisai), is a humanized monoclonal antibody that eliminates toxic amyloid-ß protofibrils that is set to follow aducanumab as the next approved treatment for patients with early Alzheimer disease. The FDA is set to decide on the treatment's approval by January 6, 2023. In the phase 3 Clarity AD study (NCT01767311), one of the supporting trials for its new drug application, lecanemab showed a statistically significant 27% reduction in the primary end point of Clinical Dementia Rating-Sum of Boxes when compared with placebo over an 18-month treatment period (P = .00005). Investigators reported an ARIA-edema rate of 12.5% for those on lecanemab compared with 1.7% for those on placebo. Symptomatic ARIA-E occurred at a rate of 2.8% in the lecanemab group and 0.0% in the placebo group. Looking for more Alzheimer disease discussion?
