Biomarker Qualification for Risk of Mild Cognitive Impairment (MCI) Due to Alzheimer's Disease (AD) and Safety and Efficacy Evaluation of Pioglitazone in Delaying Its Onset

Summary

The purpose of this study is to qualify the biomarker risk algorithm for prognosis of the risk of developing Mild Cognitive Impairment due to Alzheimer's Disease (MCI-AD), and also to evaluate the efficacy of pioglitazone compared with placebo to delay the onset of MCI-AD in cognitively-normal participants who are at high-risk for developing MCI within 5 years.
