A Study of 18F-AV-45 in Alzheimer's Disease (AD) and Healthy Volunteers

May 8, 2012 updated by: Avid Radiopharmaceuticals

Test-retest Reproducibility of 18F-AV-45 for Brain Imaging of Amyloid in Healthy Volunteers and Alzheimer's Disease Patients

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).

Description

Inclusion Criteria (AD group):

  • Greater than 50 years of age
  • Probable AD according to the National Institute of Neurological and Communication Disorders and Stroke-Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria
  • Mild/moderate dementia as evidenced by a Mini-Mental State Examination (MMSE) score ranging from 10 to 24, boundaries included, at screening
  • History of cognitive decline gradual in onset and progressive over a period of at least 6 months

Inclusion Criteria (healthy volunteer group):

  • 35 to 55 years of age, inclusive
  • MMSE of 29 or greater

Exclusion Criteria (both groups):

  • Neurodegenerative disorders other than AD, including, but not limited to Parkinson's disease, Pick's disease, fronto-temporal dementia, Huntington's chorea, Down syndrome, Creutzfeldt-Jacob disease, normal pressure hydrocephalus, and progressive supranuclear palsy
  • 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

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: AD Subjects
Two bolus IV injections followed by brain PET scan up to 4 weeks apart
Drug: florbetapir F 18
IV injection, 370MBq (10mCi)
Other Names:
  • Amyvid
  • 18F-AV-45
  • florbetapir
Experimental: AD Subjects: Slow vs. Fast Bolus

Two bolus IV injections followed by a brain PET scan up to 4 weeks apart.

Drug: florbetapir F 18
IV injection, 370MBq (10mCi)
Other Names:
  • Amyvid
  • 18F-AV-45
  • florbetapir
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:
  • Amyvid
  • 18F-AV-45
  • florbetapir

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
50-70 min after injection
