flag Oral semaglutide failed to slow cognitive decline in early Alzheimer’s patients despite biomarker improvements.

flag Novo Nordisk announced that oral semaglutide, the active ingredient in Ozempic and Wegovy, did not slow cognitive decline in two Phase 3 trials involving over 3,800 adults with early Alzheimer’s disease, despite improvements in biomarkers. flag The drug was safe and well-tolerated but failed to meet its primary endpoint of delaying disease progression compared to placebo. flag The trials, which included patients with mild cognitive impairment or mild dementia and confirmed amyloid positivity, will not be extended. flag Experts suggest the lack of clinical benefit may stem from late-stage treatment or limited brain penetration, while researchers continue to explore the drug’s biological effects. flag Full results are set for presentation at upcoming conferences.
