Trial Outcomes & Findings for A Phase II Trial of Florbetapir (18F) Positron Emission Tomography (PET) Imaging in Japan of Healthy Volunteers, Patients With Mild Cognitive Impairment (MCI) and Patients With Alzheimer's Disease (AD) (NCT NCT01662882)

NCT ID: NCT01662882

Last Updated: 2013-09-19

Results Overview

Five 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.
