Eye scan could spot Alzheimer's without brain scans
NCT ID NCT06514001
First seen Jun 27, 2026 · Last updated Sep 01, 2026 · Updated 2 times
Summary
This study tests a single injection of AMDX-2011P, a dye that may stick to Alzheimer's-related plaques in the retina. Researchers want to see if it is safe and can detect these plaques using eye imaging. 25 adults with confirmed Alzheimer's will participate. If successful, this could lead to a simpler, less expensive way to diagnose Alzheimer's.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Confirmed diagnosis of Alzheimer's Disease (AD) with documented positive amyloid beta signal via positron emission tomography (PET) brain scan 2. Must be willing to consent to genotyping for apolipoprotein E (APOE) 3. Ability to fixate and undergo retinal imaging of both eyes Exclusion Criteria: 1. Presence of any underlying physical or psychological medical condition that, in the opinion of the investigator, would make it unlikely that the participant will complete the study per protocol 2. Diagnosis of glaucoma, or suspect of having glaucoma in either eye as determined by an ophthalmologist as a clinical investigator, based on results from the eye examination, visual field, and/or optical coherence tomography (OCT) results 3. Diagnosis of intermediate dry, wet/neovascular, or geographic atrophy forms of age-related macular degeneration (AMD) in either eye, OR as determined by an ophthalmologist as a clinical investigator, based on results from the eye examination and/or optical coherence tomography (OCT) results 4. Clinically significant laboratory abnormalities as assessed by the investigator 5. Prolonged QTcF (corrected QT interval by Fridericia method) (\>450 ms for males and \>470 ms for females), cardiac arrhythmia, or any clinically significant abnormality in the resting electrocardiogram (ECG), as judged by the investigator.
