Brief Summary

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

The overall goal of this imaging trial is to evaluate \[18F\]MNI-952 (also known as \[18F\]UCB-K), a tau targeted PET radioligand.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The overall goal of this imaging trial is to evaluate \[18F\]MNI-952 (also known as \[18F\]UCB-K), a tau targeted PET radioligand.

* To characterize \[18F\]MNI-952, a PET radioligand for imaging tau.
* To visually and quantitatively assess brain uptake and pharmacokinetics of \[18F\]MNI-952, a PET imaging marker for tau pathology in individuals with Progressive Supranuclear Palsy (PSP) or Alzheimer's disease (AD) and compare with healthy volunteers (HV).
* To evaluate the safety of a single injection of \[18F\]MNI-952.
* To compare the distribution of tau (using \[18F\]MNI-952) and Aâ (using florbetapir) in AD subjects.

Eligibility Criteria

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

Inclusion Criteria

* Written informed consent must be obtained before any assessment is performed.
* Female subjects must be documented by medical records or physician's note to be either surgically sterile (by means of hysterectomy, bilateral oophorectomy, or tubal ligation) or post-menopausal for at least 1 year or, if they are of child-bearing potential, must commit to use a barrier contraception method for the duration of the study.
* Male subjects and their partners of childbearing potential must commit to the use of two methods of contraception, one of which is a barrier method for male subjects for the study duration.
* Male subjects must not donate sperm for study duration and for 90 days following participation.
* Willing and able to cooperate with study procedures


* Males and females aged \<55 years. Healthy with no clinically relevant finding on physical examination at screening and upon reporting for the \[18F\]MNI-952 imaging visit.
* No neurologic impairment as judged by the investigator
* No family history of Alzheimer's disease or neurological disease associated with dementia
* Have a CDR score=0


* Males and females aged between 50 and 90 years.
* Have probable Alzheimer's disease, based on the NINCDS/ADRDA and DSM-IV criteria.
* Have a CDR score of 0.5 or greater at screening.
* Have an MMSE score ≤ 28.
* Have a screening \[18F\]florbetapir PET imaging demonstrating amyloid binding based on qualitative (visual read)

* Males and females aged 50 to 90 years.
* Has a clinical diagnosis of PSP based on the NINDS and Society for PSP criteria (Litvan, et al 1996).
* Have screening DaTSCAN SPECT imaging demonstrating evidence of dopamine transporter deficit based on qualitative (visual) read.

Exclusion Criteria

* Medications taken for symptomatic treatment of AD must be maintained on a stable dosage regimen for at least 30 days before the screening visit
* The subject has an appropriate caregiver capable of accompanying subject, if necessary.
* Signed and dated written informed consent obtained from the subject and/or the subject's legally authorized representative or caregiver (if applicable).

* Medications taken for symptomatic treatment of PSP must be maintained on a stable dosage regimen for at least 30 days before screening visit.
* The subject has an appropriate caregiver capable of accompanying subject, if necessary.
* Signed and dated written informed consent obtained from the subject and the subject's legally authorized representative or caregiver (if applicable).


* Current or prior history of any alcohol or drug abuse.
* Laboratory tests with clinically significant abnormalities and/or clinically significant unstable medical illness.
* Subject has received an investigational drug or device within 30 days of screening
* Prior participation in other research protocols or clinical care in the last year such that radiation exposure exceeds the effective dose of 50 mSv, which would be above the acceptable annual limit established by the US Federal Guidelines.
* Pregnancy, lactating or breastfeeding.
* Evidence of clinically significant gastrointestinal, cardiovascular, hepatic, renal, hematological, neoplastic, endocrine, alternative neurological, immunodeficiency, pulmonary, or other disorder or disease.
* Unsuitable veins for repeated venipuncture.
* Implants such as implanted cardiac pacemakers or defibrillators, insulin pumps, cochlear implants, metallic ocular foreign body, implanted neural stimulators, CNS aneurysm clips and other medical implants that have not been certified for MRI, or history of claustrophobia in MRI.
