Evaluating the Relationship Between Tau PET Imaging and CSF Biomarkers of AD in Humans
The purpose of this research study is to evaluate a new radioactive compound used in positron
emission tomography (PET) scans in identifying tau tangles (a certain protein that might be
associated with Alzheimer's disease) in the brain, and if the amount of tau tangles in the
brain has a relationship to cerebrospinal fluid (CSF) biomarkers and cognitive status.
This study involves a PET scans using the radioactive compound, F 18 T807 for measurement of
tau deposition. This radioactive compound is not approved by the United States Food and Drug
Administration (FDA). An MRI will be conducted if one has not been completed completed within
the past 12 months under a related research study. Participants will be asked about their
medical history, family history, surgical history, and current medications. We will evaluate
history of traumatic brain injury (TBI) using the Ohio State University Traumatic Brain
Injury Identification (OSU TBI-ID) Method. This will take approximately 10 minutes.
Participants will be asked to undergo a Mini Mental State Examination (MMSE), which will last
approximately 5-10 minutes.
Additionally, participants may be invited to undergo optional brain PET imaging with
2-deoxy-2-[18F]fluoro-D-glucose fludeoxyglucose (18F-FDG), for measurement of the cerebral
metabolic rate of glucose consumption. At the time of the initial T807-PET study,
participants will be asked if they are willing to undergo repeat T807-PET imaging at least 2
years after the initial study. This follow up study is optional, and participation in the
study and initial T807-PET imaging will not be contingent on agreeing to the 2-year follow up
study.

Inclusion Criteria:
1. Male or female participants, at least 65 years of age.
2. Participant is willing to undergo a lumbar puncture (LP) or has previously undergone
LP. LP will be conducted under IRB ID 201109100 (PI: Anne Fagan).
3. Participant is able and willing to undergo positron emission tomography (PET) and
magnetic resonance imaging (MRI) of the brain.
4. Pre-menopausal women must have a negative urine pregnancy test within 24 hours
preceding T807 drug administration.
Exclusion Criteria:
1. Has any condition that, in the Investigator's opinion, could increase risk to the
participant, limit the participant's ability to tolerate the experimental procedures,
or interfere with the collection/analysis of the data (for example, participants with
severe chronic back pain might not be able to lie still during the scanning
procedures).
2. Is deemed likely unable to perform the imaging procedures for any reason.
3. Has a history of Torsades de Pointes or is taking medications known to prolong or may
prolong QT interval (refer to study's list of restricted medications).
4. Has known hypersensitivity to T807 or any of its excipients.
5. Contraindications to PET, PET-CT or MR (e.g. electronic medical devices, inability to
lie still for long periods) that make it unsafe for the individual to participate.
6. Severe claustrophobia.
7. Currently pregnant or breast-feeding. -
