Study Description
Brief Summary:
Evaluate 18F-AV-45 positron emission tomography (PET) imaging for distinguishing healthy control subjects, from subjects with Alzheimer's disease (AD) or Mild cognitive impairment (MCI).

Condition or disease Intervention/treatment Phase
Alzheimer's Disease Mild Cognitive Impairment Drug: florbetapir F 18 Phase 2

Study Design

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 184 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Diagnostic
Official Title: An Open Label, Parallel Group, Multicenter Study, Evaluating the Safety and Imaging Characteristics of 18F-AV-45 in Healthy Volunteers, Patients With Mild Cognitive Impairment (MCI) and Patients With Alzheimer's Disease (AD)

Outcome Measures

Primary Outcome Measures :
  1. Qualitative Amyloid Image Assessment [ Time Frame: 50-60 min after injection ]
    Three readers blinded to all clinical information classified florbetapir-Positron Emission Tomography (PET) images as either positive for amyloid or negative for amyloid. The majority read was the primary efficacy endpoint for the qualitative evaluation.

  2. 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 whole cerebellum.


Secondary Outcome Measures :
  1. Proportion of Positive Florbetapir-PET Scans [ Time Frame: 50-60 min after injection ]
    Three readers blinded to all clinical information classified florbetapir-PET images as either positive for amyloid or negative for amyloid. The majority read was used to determine the proportion of positive scans across the three groups.
