Evaluating the Efficacy and Safety of Lecanemab in Alzheimer's Disease Through Multi-omics Approachs

May 17, 2026 updated by: First Affiliated Hospital of Wenzhou Medical University

Multicenter, Randomized, Controlled Study Evaluating the Efficacy and Safety of Lecanemab in Alzheimer's Disease Through Multi-omics Approachs

This research proposal outlines a multi-center, randomized, trial. Patients diagnosed with early-to-moderate Alzheimer's Disease will be recruited. Participants will be randomly assigned to receive either Lecanemab. The study will run over a period of 24 months, with evaluations conducted at baseline, 6 months, and 12 months, 18 months and 24 months. Data from multiple omics layers will be integrated to assess both the efficacy and safety of the treatment.

The primary aim of this study is to assess the efficacy and safety of Lecanemab in patients with Alzheimer's Disease, leveraging multi-omics approaches. Specifically, the study will integrate data from OCT/OCTA imaging of the eye and MRI imaging of the brain, as well as cognitive measures such as ADAS-Cog, MoCA and CDR scores. Furthermore, the presence of ARIA-a significant safety concern in amyloid-targeting therapies-will be closely monitored. The study seeks to provide a more robust understanding of Lecanemab's impact on disease progression, cognition, and potential adverse effects, contributing to a more informed clinical application of this treatment in Alzheimer's care.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
