description: "Eisai Co., Ltd. and Biogen Inc. presented findings on lecanemab, an anti-amyloid beta antibody for early Alzheimer's disease, at the CTAD Conference. Long-term studies showed that continued treatment with lecanemab resulted in significant cognitive improvements and reduced disease progression risk. A new method for measuring protofibrils in cerebrospinal fluid was developed, revealing a strong correlation with neurodegenerative biomarkers. The data suggest that early initiation of lecanemab treatment may positively impact disease progression in early Alzheimer's patients, with no new safety concerns reported over three years of treatment."
