Evaluation System for Lecanemab Efficacy Using Gold Electrode ECL to Monitor Alzheimer's Biomarkers (ECL-Lecanemab)
Construction of a Lecanemab Therapeutic Efficacy Evaluation System Based on Mesoporous Gold Electrode Surface-enhanced Electrochemiluminescence for Monitoring Dynamic Changes of Alzheimer's Disease Plasma Biomarkers
Studieoversikt
Detaljert beskrivelse
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.

Eksperimentell: Experimental: Lecanemab Treatment Group
Participants in this arm will receive Lecanemab treatment according to the standard clinical protocol for Alzheimer's disease.
Their plasma biomarkers will be monitored using the mesoporous gold electrode ECL system to evaluate therapeutic efficacy.
|
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.

Change in Plasma Alzheimer's Biomarkers
Tidsramme: Baseline and every 4 weeks during the 18-month treatment period
|
The 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.
