Brief Summary:
This study will test if two AV-45 PET scans up to 4 weeks apart in AD subjects and healthy volunteers provide the same results. The study will also test two different AV-45 injection methods in a small subgroup of enrolled AD subjects (slow vs. fast bolus group).

Arm Intervention/treatment
Experimental: AD Subjects
Two bolus IV injections followed by brain PET scan up to 4 weeks apart

Experimental: Healthy controls
Healthy male or female subjects; 35-55 years old. Two bolus IV injections followed by brain PET scan up to 4 weeks apart
 Drug: florbetapir F 18
IV injection, 370MBq (10mCi)
Other Names:
  • 18F-AV-45
  • Amyvid
  • florbetapir


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Mean Cortical to Cerebellum SUVR [ Time Frame: 50-70 min after injection ]
    Standardized Uptake Value ratio (SUVR) is the ratio of tracer uptake in predefined cortical regions, relative to uptake in the whole cerebellum.

Criteria

Inclusion Criteria (AD group):

  • Diagnosis of other dementing / neurodegenerative disease
  • Diagnosis of mixed dementia
  • Cognitive impairment resulting from trauma, hypoxic damage, vitamin deficiency, brain infection, brain cancer, endocrine disease, or mental retardation
  • Clinically significant infarct or possible multi-infarct dementia as defined by the NINCDS criteria
  • Evidence on screening MRI or other biomarker that suggests alternate etiology for cognitive deficit (for healthy controls, evidence suggesting the presence of AD pathology)
  • Clinically significant psychiatric disease
  • History of epilepsy or convulsions
  • Clinically significant hepatic, renal, pulmonary, metabolic, or endocrine disturbances
  • Current clinically significant cardiovascular disease
  • Received investigational medication within the last 30 days
