• The UK's medicines regulator (MHRA) has approved lecanemab for Alzheimer's disease, but NICE has deemed it not cost-effective for NHS use in England and Wales, limiting access to private patients willing to pay approximately £20,000 annually.
• Lecanemab, sold as Leqembi, works with the immune system to reduce amyloid protein buildup and has shown to slow cognitive decline by 27% and quality of life decline by up to 56% in early-stage Alzheimer's patients during clinical trials.
• Alzheimer Scotland has criticized NICE's decision as "short-sighted" and urged the Scottish Medicines Consortium to approve the drug, arguing it represents a crucial first step in disease-modifying treatment despite being suitable only for patients in early disease stages.
