Official title
A Clinicopathological Study to Evaluate the Concordance Between [18F]-APN-1607 Injection PET Imaging and Post-mortem Brain Tau Protein Pathological Changes in Cognitively Normal (HV) Subjects and Patients With AD-derived Mild Cognitive Impairment (MCI) or Alzheimer's Disease (AD) Dementia.
Overview
1. To evaluate the diagnostic performance of \[18F\]-APN-1607 injection PET imaging in detecting uptake patterns consistent with AD neuropathological changes as defined by the National Institute on Aging-Alzheimer's Association (NIA-AA) criteria. 2. To assess the association between \[18F\]-APN-1607 injection and Alzheimer's disease (AD)-related tau neurofibrillary pathology (as determined by post-mortem brain tissue histopathology), and detect the uptake pattern corresponding to neurofibrillary tangle (NFT) scores. 3. To evaluate the safety of \[18F\]-APN-1607 injection.
Interventions
- Drug [18F]-APN-1607
Participants will receive a single intravenous injection of 5-7 mCi of \[18F\]-APN-1607, and a whole-body PET/CT scan will begin immediately after administration
Primary outcome measures
- Evaluate the consistency between the visual interpretation results of [18F]-APN-1607 injection PET imaging and the authenticity standards. [Time frame: 8 months]
Secondary outcome measures (2)
- Correlation between the results of semi-quantitative PET imaging analysis (SUVR) and brain tissue pathological NFT scores. [Time frame: 8 months]
- Evaluation of the safety of [18F]-APN-1607 injection. [Time frame: 8 months]
