Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to assess \[18F\]MNI-777 PET imaging as a tool to detect tau pathology in the brain of individuals who carry a clinical diagnosis of a tauopathy, including: Alzheimer's Disease (AD),Parkinson's disease (PD) Progressive Supranuclear Palsy (PSP), chronic traumatic encephalopathy (CTE) and Frontal Temporal Dementia (FTD) and age- and gender-matched healthy subjects.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

[18F]T807 ([18F]MNI-777)

At the \[18F\]MNI-777 PET imaging visit, subjects will be injected with no more than 10 mCi (370 MBq) of \[18F\]MNI-777).

Group Type EXPERIMENTAL

[18F]T807 ([18F]MNI-777)

Intervention Type DRUG

All enrolled subjects will undergo an \[18F\]MNI-777 PET imaging visit. For individuals with AD or CTE, \[18F\]florbetapir imaging may also be performed to serve as a means of correlating disease severity by evaluating the relationship of β-amyloid uptake (measured by \[18F\]florbetapir imaging) and tau protein uptake (measured by \[18F\]MNI-777 PET imaging). For individuals with Parkinsonian symptoms, \[123I\]β-CIT SPECT imaging may be performed to evaluate for a reduction in dopamine transporter uptake.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

For all subjects:

* Written informed consent or assent is obtained.
* Willing and able to cooperate with study procedures.
* For females, non-child bearing potential or negative urine pregnancy test on day of \[18F\]MNI-777 injection.

Alzheimer Disease subjects:

* The participant is 50 years or older.
* Participants have a clinical diagnosis of Alzheimer's disease based on National Institute of Neurological and Communicative Disorders and Stroke/Alzheimer's Disease and Related Disorders Association (NINCDS/ADRDA) criteria (McKann, 1984)
* Modified Hachinski Ischemia Scale score of ≤ 4.

Parkinson's Disease subjects:

* The participant is 30 years or older.
* Participants have a clinical diagnosis of PD based on the UK Brain Bank Criteria (Hughes, et al., 1982).
* The duration of diagnosis of PD is \<20 years prior to the imaging visit
* PD subjects must be on stable doses of medications for a period of at least 30 days prior to the imaging visit.
* Treatment with dopamine replacement therapies or other symptomatic therapies for PD is permitted; however, subjects must be on a stable dose of medications 30 days prior to the imaging visit.

Progressive Supranuclear Palsy subjects:

* The participant is 30 years or older.
* Participants have a clinical diagnosis of PSP based on National Institute of Neurological Disorders and Stroke/ (NINDS) and the Society for PSP (SPSP) criteria (Litvan, et al. 1996).

Chronic Traumatic Encephalopathy subjects:

* The participant is 18 years or older.
* Subjects with a diagnosis of probable CTE based on a prior history of repetitive brain trauma and at least one concussion, and a current mood disorder (depression, apathy, irritability, suicidal ideation), cognitive symptoms (memory loss, impaired executive function) or behavioral symptoms (disinhibition, aggression and increased violence) (Jordan, 2013).

Frontal Temporal Dementia/Pick's disease subjects:

* The participant is 50 years or older.
* Participants have a clinical diagnosis of FTD based on consensus for clinical diagnosis of frontotemporal dementia (Neary, et al., 1998)

Healthy Control subjects:

* The participant is 18 - 85 years old.
* Negative history of neurological or psychiatric illness based on evaluation by a research physician.
* MMSE score must be 29 or above.

Exclusion Criteria

All subjects will be excluded from participation for the following reasons:

* The subject has a clinically significant abnormal laboratory value and/or clinically significant unstable medical or psychiatric illness.
* The subject has any disorder that may interfere with drug absorption distribution, metabolism, or excretion (including gastrointestinal surgery).
* The subject has evidence of a structural lesion on MRI that may interfere with interpretation of PET imaging.
* The subject has evidence of clinically significant gastrointestinal, cardiovascular, hepatic, renal, hematological, neoplastic, endocrine, neurological, immunodeficiency, pulmonary, or other disorder or disease.
* The subject has participated in another clinical study within the previous 30 days.
* Pregnancy or women who are nursing or breastfeeding
