A Preliminary Study of 18F-AV-45 in Alzheimer's Disease and Healthy Elderly Volunteers - Full Text View

Purpose

A preliminary study to test how florbetapir F 18 (18F-AV-45) acts in the brains and bodies of healthy elderly people and patients with Alzheimer's Disease (AD) by using a positron emission tomography (PET) scanner.

Primary Outcome Measures:

Mean Cortical to Cerebellum SUVR [ Time Frame: 50-60 min after injection ]
Standardized Uptake Value ratio (SUVR) is the ratio of tracer uptake in predefined cortical regions, relative to uptake in the cerebellum gray matter. Total scan length was 200 min.

Secondary Outcome Measures:

Precuneus to Cerebellum SUVR [ Time Frame: 50-60 min after injection ]
Ratio of uptake in the precuneus to uptake in the cerebellum.


Enrollment:	32

Primary Completion Date:	January 2008 (Final data collection date for primary outcome measure)

Accepts Healthy Volunteers:	Yes

Criteria

Inclusion Criteria (AD group):

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 exam (MMSE) score ranging from 10 to 24, boundaries included, at screening
History of cognitive decline had been gradual in onset and progressive over a period of at least 6 months

Inclusion Criteria (healthy volunteer group):

No evidence of significant cognitive impairment by history and psychometric testing
MMSE of 29 or higher

Exclusion Criteria (both groups):

Neurodegenerative disorders other than AD
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
