Immunization Strategy as a Potential Approach to Slowing Cognitive Decline in AD: Jean-Cosme Dodart, PhD
The senior vice president of research at Vaxxinity discussed recently published trial findings on a novel vaccine that targets Alzheimer disease and triggers the production of antibodies against toxic amyloid-ß peptides. [WATCH TIME: 9 minutes]

"The paper that was published includes all the methods and data that we collected in a phase 2 clinical trial in early Alzheimer disease. We designed the trial well; it was a very small cohort that led to very encouraging results. We tried 2 different treatment regimens of the same dose of our vaccine and we confirmed that first it was safe and well tolerated."
UB-311 (Vaxxinity), a synthetic, peptide-based active immunotherapy, is designed to combat toxic amyloid-ß oligomers and fibrils, with potential benefits for patients with Alzheimer disease (AD). These benefits encompass reduction in incidence of amyloid-related imaging abnormalities-edema/effusion (ARIA-E), convenience because of less frequent dosing, and simplicity of administration through intramuscular injection. Furthermore, the vaccine therapy aims to elevate both patient access and cost-effectiveness, which can be also beneficial for both patients and healthcare systems.1
