Fluselenamyl Tracer for Amyloid PET Imaging of Alzheimer's Disease

Start: Nov. 18, 2022
End: March 2024
Enrollment: 60

What Is This Study About?

Amyloid is a protein that forms plaques and is one of the hallmarks of Alzheimer's disease. During an amyloid PET brain scan, small amounts of a radioactive tracer are used to visualize amyloid in the brain. This study will test the safety and effectiveness of the radioactive tracer 18F-Fluselenamyl in people with normal cognition or early Alzheimer's. In the first stage of the study, participants with normal cognition will receive whole body PET-CT scans using different amounts of the 18F-Fluselenamyl tracer to determine dosage. In stage 2, all participants will complete cognitive tests and undergo PET imaging of the head and neck with the 18F-Fluselenamyl tracer. For comparison, an MRI scan and PET scan with another tracer, 11C-PIB, will also be collected. After 18 months, the imaging tests in stage 2 will be repeated in all participants. Throughout the study, all participants will be monitored for side effects.

Do I Qualify To Participate in This Study?

Minimum Age: 18 Years

Maximum Age: N/A

Must have:

  • Normal cognition, mild cognitive impairment, or Alzheimer's disease

Must NOT have:

  • Allergy to 18F-Fluselenamyl, 11C-PIB, or any of their components
  • Unwilling or unable to undergo PET scan tracer injections
  • Unwilling or unable to undergo MRI brain scan, including any condition that may make having an MRI brain scan unsafe (e.g., metal shrapnel, heart pacemaker, severe claustrophobia, epilepsy
  • Current or past participation within the last year in another research study involving radioactive agents such that, combined with this study, would exceed safe radiation limits
  • Women must not be pregnant or breastfeeding
  • Any medical condition (e.g., renal or liver failure, advanced cancer) that could:
    • Increase study risk for the participant
    • Limit the participant's ability to tolerate the study procedures, or
    • Interfere with the collection or analysis of the study data
