Brief Summary

The overall objective of this study is to evaluate the overall pattern of [18F]APN-1607 uptake in subjects with AD dementia

Detailed Description

• To expand the safety and tolerability profile for the administration of [18F]APN-1607 and PET scanning.
• To assess regional patterns of [18F]APN-1607 uptake.
• To evaluate the relationship between regional measures of [18F]APN-1607 uptake and measurements of AD disease severity, such as National Institute on Aging and Alzheimer's Association (NIA-AA) diagnosis, Mini-mental Status Exam (MMSE) score, and Alzheimer's Disease Assessment Scale-cognitive subscale (ADAScog).

Conditions

Alzheimer Disease

Study Design

Study Groups

[18F]APN-1607

For the injection, subjects will receive a target dose of 0.1\~0.15mCi/Kg \[18F\]APN-1607 as a bolus injection.

Group Type: EXPERIMENTAL

[18F]APN-1607

Intervention Type: DRUG

Subjects will receive one injection of \[18F\]APN-1607 (0.1\~0.15mCi/Kg), a PET radiopharmaceutical selective for fibrillar tau. \[18F\]APN-1607 injection will be followed by a 10 ml saline flush.

Eligibility Criteria

Inclusion Criteria

• Male or female aged 45 to 80 years, inclusive.
• Has a diagnosis of AD dementia according to NIA-AA criteria, including significant impairment of activities of daily living.
• Has a CDR score ≥ 0.5 at screening.
• Has a MMSE score ≤ 25.
• Brain MRI supports the diagnosis of AD and there is no evidence of other nervous system diseases.
• Medications taken for symptomatic treatment of AD must have been stable for 30 days prior to screening and through completion of the neuropsychological battery.
• If necessary, the subject can be accompanied by nursing staff.
• 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 (ie, 12 consecutive months with no menses without an alternative medical cause) or, if they are of childbearing potential, must commit to use a barrier contraception method or to abstinence for the duration of the study and must have negative serum and urine pregnancy tests.
• 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 (ie, condom), or to abstinence for the study duration.
• Male subjects must not donate sperm for the study duration.
• Willing and able to participate in all study procedures.

Exclusion Criteria

• Evidence of clinically significant gastrointestinal, cardiovascular, hepatic, renal, hematological, neoplastic, endocrine, alternative neurological, immunodeficiency, pulmonary, or other disorder or disease.
• 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.
• Intolerance to MRI noise or hermetic phobia.
• Prior participation in other research protocols or clinical care in the last year in addition to the radiation exposure expected from participation in this clinical study, such that radiation exposure exceeds local guidelines, eg, above an effective dose of 50 mSv.
• Current or prior history (within the last 10 years) of alcohol or drug abuse.
• Pregnant, lactating or breastfeeding.
• Unsuitable veins for repeated venipuncture
• Has received any investigational drug or device for any purpose within 30 days of screening (or 5 half-lives of the drug, whichever is longer).
• Known hypersensitivity to [18F]APN-1607 or its excipients
• Has received a non-vaccine investigational treatment for Aβ within the last 3 months.
• Has received a non-vaccine investigational treatment for tau within the last 3 months.
• Any situation that the presiding officer of this study believes may cause harm or potential harm to any link related to this test.

• Minimum Eligible Age: 45 Years
• Maximum Eligible Age: 80 Years
