To investigate whether [18F]NAV4694 positron emission tomography (PET) scan findings have the
ability to distinguish subjects with mild cognitive impairment (MCI) who progress to
Alzheimer's disease (AD) from those who do not.


Inclusion Criteria:

- Subject has signed informed consent to participate in the study and continues to give
willing consent for participation

- Age ≥ 55 years with a diagnosis of MCI

- Educational level of at least 6 years

- Female subjects will not be of child-bearing potential (> 1 year post-menopausal or
surgically sterile)

- Availability of a "study partner" who can assist in completing rating scales for the
duration of the study

- Cognitive complaints reported by the subject and confirmed by the "study partner"

- Clinical Dementia Rating (CDR) global score = 0.5

- Mini-mental state examination (MMSE) score of 24-30

- Diagnostic and Statistical Manual of Mental Disorders, Version 4, Text Revised
(DSM-IV-TR) criteria of dementia not fulfilled

Exclusion Criteria:

- Has been previously enrolled in this study and received the investigational product

- Has received an investigational product within 30 days prior to screening

- Has received disease-modifying therapy that could have changed amyloid brain
deposition

- Has exceeded yearly radioactive dose of 30 mSv

- Has a known allergy to the study drug or any of its constituents

- Has a history of alcohol abuse or alcohol dependency in the 3 years prior to study
entry, or is an alcoholic or drug addict, as determined by the investigator

- Has ongoing clinically significant (as judged by the investigator), metabolic or any
other disease that could currently cause impaired memory (e.g., untreated thyroid
disease, vitamin or other nutritional deficiencies, chronic kidney, or liver disease)

- Memory impairment that can be attributed to a disease or condition other than an early
phase neurodegenerative syndrome

- Has a parkinsonian movement disorder

- Use of psychoactive medications that would affect the subject's ability to reliably
perform neurocognitive testing or create uncertainty in distinguishing between the
effects of the psychoactive medication and the subject's underlying cognitive
impairment (e.g., benzodiazepines, sedatives, antipsychotics)

- Has received any contrast material (X-ray, MRI) or radiopharmaceutical within 48 hours
prior to, or a therapeutic radiopharmaceutical (e.g., 131I) within 10 days prior to,
or any radiopharmaceutical administration within 10 radioactive half-lives prior to
the administration of the investigational product or for whom administration of such
substances is planned within 7 days after investigational product administration

- History of major recurrent depressive disorder (per DSM-IV-TR) within the last 5 years
prior to screening

- Has a brain tumor or other intracranial lesion, a disturbance of cerebral spinal fluid
circulation (e.g., normal pressure hydrocephalus), and/or a significant history of
head trauma or brain surgery

- Has signs of major cerebrovascular disease, as verified by medical history and/or
brain MRI

- Is scheduled for surgery and/or another invasive procedure within the 7 days following
investigational product administration

- Has any contraindication to MRI examination, e.g., metal implants, phobia, or cannot
undergo an MRI for other reasons such as the inability to lie flat
