Clinical trial for Alzheimer Disease
Official title Longitudinal Imaging of Microglial Activation in Different Clinical Variants of Alzheimer's Disease
ClinicalTrials.gov ID: NCT04576793
What this study is testing
What is 11C-ER176?
An investigational radioactive tracer being studied for measuring brain inflammation in Alzheimer’s disease.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study wants to learn how brain inflammation is linked to other brain changes and early symptoms in Alzheimer’s disease.
- Who it's for
- It looks for people with mild cognitive impairment, posterior cortical atrophy, logopenic variant primary progressive aphasia, amnestic Alzheimer’s disease, and older adults with normal memory, vision, and language.
- What's involved
- Participants will have brain scans that measure microglial activation and may do other tests to track brain changes.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
Who can take part
Ages 50 and older. Healthy volunteers may be eligible.
You may be able to join if
- Age 50 and over at time of screening.
- At screening, must have no cognitive impairment, or meet criteria for amnestic Alzheimer's disease, posterior cortical atrophy, or logopenic variant...
- Patients must have Clinical Dementia Rating scale score of 0.5 or 1 at enrollment.
- people unable to provide informed consent must have a surrogate decision maker.
- Written and oral fluency in English or Spanish.
You likely can't join if
- Past or present history of a brain disorder other than Alzheimer's disease (including presence of cortical infarct on MRI even in absence of clinical...
- Serious medical conditions, which make study procedures of the current study unsafe.
- Contraindication to MRI scanning.
- Conditions precluding entry into the scanners (e.g. morbid obesity, claustrophobia, etc.).
- Exposure to research related radiation in the past year that, when combined with this study, would place people above the allowable limits.
- Exact medication exclusions are up to the discretion of the PI in consultation with the MD liaison.

- Age 50 and over at time of screening.
- At screening, must have no cognitive impairment, or meet criteria for amnestic Alzheimer's disease, posterior cortical atrophy, or logopenic variant primary progressive aphasia.
- Patients must have Clinical Dementia Rating scale score of 0.5 or 1 at enrollment. Controls must have Clinical Dementia Rating scale score of 0 at enrollment.
- people unable to provide informed consent must have a surrogate decision maker.
- Written and oral fluency in English or Spanish.
- Able to participate in all scheduled evaluations and to complete all required tests and procedures.
- In the opinion of the PI, the subject must be considered likely to comply with the study protocol and to have a high probability of completing the study.
- Past or present history of a brain disorder other than Alzheimer's disease (including presence of cortical infarct on MRI even in absence of clinical stroke).
- Serious medical conditions, which make study procedures of the current study unsafe. Such serious medical conditions include uncontrolled epilepsy and multiple serious injuries.
- Contraindication to MRI scanning.
- Conditions precluding entry into the scanners (e.g. morbid obesity, claustrophobia, etc.).
- Exposure to research related radiation in the past year that, when combined with this study, would place people above the allowable limits.
- Exact medication exclusions are up to the discretion of the PI in consultation with the MD liaison.
