Résumé succinct
As the population increases and aging intensifies, cognitive disorders represented by Alzheimer's disease (AD) not only pose a severe threat to public health but also bring significant social and economic burdens. Previously, treatment options for Alzheimer's disease were very limited, mainly providing symptomatic relief with few available medications. Lecanemab, an FDA-approved clinical treatment drug in 2023, targe...Afficher plus

Treated Group This is an observational study. The investigators included early AD patients treated with Lecanemab, and evaluated them by plasma, magnetic resonance imaging (MRI) examination and clinical scale. The investigators observed the changes in MRI characteristics and clinical symptoms of patients after Lecanemab administration, evaluated the improvement effect of Lecanemab on cognitive function, and monitored the risk fact...Afficher plus | Lecanemab 10 mg/kg Lecanemab was administered 10mg/kg every two weeks. |
Critère principal d'évaluation
Critère secondaire d'évaluation
| Critères d'évaluation | Description de la mesure | Période |
|---|---|---|
CDR-SB Score | All study subjects underwent Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) assessment by a specialist before the 1st dose (V1) and at 3, 6, 12, and 18 months after treatment (V7, V14, V25, V39). CDR-SB, with total scores ranging from 0 to 18, can be used to measure cognitive changes in the early stages of Alzheimer's disease, with higher scores indicating more severe symptoms. | CDR-SB scales by baseline before the 1st dose(V1) and at 3, 6, 12, and 18 months after treatment (V7, V14, V25, V39) |
MMSE | All study subjects underwent Mini Mental State Examination (MMSE) assessment by a specialist before the 1st dose (V1) and at 3, 6, 12, and 18 months after treatment (V7, V14, V25, V39). MMSE, with total scores ranging from 0 to 30, can be used to measure cognitive changes in the early stages of Alzheimer's disease, with lower scores indicating more severe symptoms. | MMSE scales by baseline before the 1st dose(V1) and at 3, 6, 12, and 18 months after treatment (V7, V14, V25, V39) |
ADCs-ADL | All study subjects underwent Alzheimer's Disease Cooperative Study-Activity of Daily Life (ADCs-ADL) assessment by a specialist before the 1st dose (V1) and at 3, 6, 12, and 18 months after treatment (V7, V14, V25, V39). CDR-SB, with total scores ranging from 0 to 78, can be used to measure activity of daily life changes in the early stages of Alzheimer's disease, with lower scores indicating more severe symptoms. | ADCs-ADL scales by baseline before the 1st dose(V1) and at 3, 6, 12, and 18 months after treatment (V7, V14, V25, V39) |
NPI | All study subjects underwent Neuropsychiatric Inventory (NPI) assessment by a specialist before the 1st dose (V1) and at 3, 6, 12, and 18 months after treatment (V7, V14, V25, V39). CDR-SB, with total scores ranging from 0 to 18, can be used to measure cognitive changes in the early stages of Alzheimer's disease, with higher scores indicating more severe symptoms. | NPI scales by baseline before the 1st dose(V1) and at 3, 6, 12, and 18 months after treatment (V7, V14, V25, V39) |

Aβ-PET Burden | All study subjects underwent Aβ positron emission tomography (PET) before the 1st dose (V1) ,at 12 and 18 months after treatment (V26,V39). The investigators quantified participants' Aβ burden using the average cortical standard uptake value ratio (SUVR), that is, tracer uptake in medial orbital frontal, lateral temporal, parietal, anterior cingulate, posterior cingulate, and precuneus regions divided by uptake in the cerebellar reference region. | Aβ-PET tested by baseline before the 1st dose(V1) , at 12 and 18 months after treatment (V25,V39) |
MRI | All study subjects underwent magnetic resonance imaging (MRI) before the 1st dose (V1) ,at 2, 3, 6,12 and 18 months after treatment. The scan includes T1, T2 fluid attenuated inversion recovery (FLAIR, 5 mm slice thickness), susceptibility weighted imaging (SWI, 1 mm slice thickness) and diffusion weighted imaging (DWI). The MRI scan can be used to meature the study subjects' hippocampus atrophy and white matter hyperintensities and to detect whether adverse events such as amyloid-related imaging abnormalities happen. | Time Frame: MRI tested by baseline before the 1st dose(V1) , at 2, 3, 6, 12 and 18 months after treatment (V5, V7, V14, V25, V39) |
Biospecimen | All study subjects underwent blood collection before the 1st dose (V1) and at 3, 6, 12, and 18 months after treatment (V7, V14, V25, V39) for routine blood tests, liver and kidney function, plasma biomarkers, and other indicators. Among them, the APOE genotype of subjects will be tested before the 1st dose. | Blood tested by baseline before the 1st dose(V1) , at 3, 6,12 and 18 months after treatment(V7, V14, V25, V39) |
