Brief summary

This study aims to evaluate the therapeutic efficacy of Lecanemab in patients with Alzheimer's disease. The researchers will use a novel detection method based on mesoporous gold electrode surface-enhanced electrochemiluminescence (ECL) to monitor specific biomarkers in the patients' plasma. By tracking changes in these biomarkers, the study seeks to determine how effectively Lecanemab treats the disease and to validate this new ECL-based monitoring system as a useful tool for clinical assessment.

Detailed description

Background: Lecanemab is an antibody used for the treatment of Alzheimer's disease (AD). Monitoring its therapeutic efficacy accurately is crucial for patient management. Traditional methods can be complex or less sensitive. This study introduces a highly sensitive electrochemiluminescence (ECL) assay using mesoporous gold electrodes to detect AD-related plasma biomarkers. Study Design: This is an observational/clinical study involving patients diagnosed with Alzheimer's disease who are receiving Lecanemab treatment. Methodology: Blood samples will be collected from participants at scheduled visits. The levels of specific AD biomarkers in the plasma will be measured using the developed mesoporous gold electrode ECL system. These measurements will be correlated with clinical outcomes to assess the drug's efficacy. The study also aims to establish the reliability and sensitivity of this specific ECL technique for routine clinical monitoring.

Interventions

Participants will receive Lecanemab (10 mg/kg) via intravenous infusion every two weeks for a total of 18 months. The dosage and frequency follow the standard prescribing information for Alzheimer's disease treatment.

Design outcomes

Primary

MeasureTime frameDescription
Change in Plasma Alzheimer's BiomarkersBaseline and every 4 weeks during the 18-month treatment periodThe concentration of specific biomarkers (e.g., Aβ42, p-Tau181) in plasma will be measured using the mesoporous gold electrode ECL system. The change from baseline to the end of treatment will be calculated to evaluate therapeutic efficacy.

Secondary

MeasureTime frameDescription
Change in CDR-SB ScoreBaseline, Month 6, Month 12, and Month 18Cognitive function will be assessed using the Clinical Dementia Rating-Sum of Boxes (CDR-SB). Scores range from 0 to 18, with higher scores indicating greater impairment. Change from baseline will be analyzed.
