Is this trial a fit for you?

Likely a good fit

Adults aged 50 to 90 with MCI due to AD or mild Alzheimer’s dementia, confirmed amyloid pathology, MMSE 22–30, CDR 0.5–1, and stable concomitant medications.

Probably not a fit

Patients without measurable biomarker changes or with advanced disease beyond the inclusion range may not derive clear benefit.

What this trial studies

This phase 4 study monitors Alzheimer’s patients receiving lecanemab and uses a novel mesoporous gold electrode electrochemiluminescence assay to measure plasma biomarkers. Blood samples are taken at set visits to correlate biomarker changes with clinical outcomes, aiming to validate the ECL method for routine monitoring. The design is observational with an intervention (lecanemab) to assess treatment efficacy alongside the biomarker assay. Eligibility focuses on adults with mild cognitive impairment due to AD or mild Alzheimer’s dementia who have confirmed amyloid pathology and stable comedications. The trial is conducted at a Zhejiang University-affiliated hospital in China, led by The Fourth Affiliated Hospital of Zhejiang University School of Medicine.

Why it matters

Potential benefit: Participants could receive closer monitoring of treatment response through the new blood-based biomarker assay if it proves reliable.

How similar studies have gone: Previous work suggests biomarker-based monitoring can reflect treatment response, but this specific ECL mesoporous gold electrode approach is novel and exploratory.
