“LEQEMBI®” (Lecanemab) Approved for Slowing the Progression of Early Alzheimer’s Disease in Singapore
Singapore, May 28, 2025 – Eisai (Singapore) Pte Ltd (Managing Director: Celine Ting) announced that Health Sciences Authority (HSA) of Singapore has approved LEQEMBI® (lecanemab)1, a globally recognized innovation for slowing the progression of Alzheimer’s disease (AD) in patients with mild cognitive impairment (MCI) or mild dementia stage of disease.
Lecanemab is the first approved Aβ monoclonal antibody that preferentially binds and clears toxic protofibrils (soluble Aβ aggregates), in addition to targeting and reducing Aβ plaques (insoluble Aβ aggregates).2-6 Protofibrils are a key toxic form of Aβ that accumulate in the brain and cause neuronal injury.3-9
The approval of LEQEMBI® is based on the large global Phase 3 Clarity AD study. In the Clarity AD study, LEQEMBI® met its primary endpoint and all key secondary endpoints with statistically significant results.2,10
Approximately 92,000 people in Singapore are estimated to suffer from dementia, with that number projected to rise to approximately 152,000 by 2030.11 AD accounts for 60-70% of all dementia diagnoses worldwide.12
Eisai serves as the lead for lecanemab’s development and regulatory submissions globally with both Eisai and Biogen co-commercializing and co-promoting the product and Eisai having final decision-making authority. In Singapore, Eisai will promote the medicine as it is the Product Registrant holder.
