Clinical Trial Summary

The proposed pilot study will provide safety and efficacy preliminary data regarding singular and combined effects of two therapeutic approaches, intranasal insulin and treatment with the sodium-glucose cotransporter type 2 inhibitor (SGLT2i) empagliflozin, to correct bioenergetic and vascular dysfunction in adults with preclinical Alzheimer's disease (AD) and amnestic mild cognitive impairment (aMCI) or early AD.


Clinical Trial Description

The study will consist of a single site, randomized, double-blind trial comparing the effects of 4 weeks of intranasal insulin(40 International Units four times daily), empagliflozin (10 mg daily) and combined intranasal insulin (INI) and empagliflozin (empa) compared with placebo on cerebrospinal fluid (CSF) biomarkers and cognition. At study entry, participants will be randomized to one of 4 conditions: INI, empa, INI+empa or placebo. Participants who are cognitively normal but have abnormal elevations of brain amyloid or who have mild cognitive impairment (MCI) or early Alzheimer's disease (AD) will be enrolled. The primary outcome measure will consist of safety (treatment-related serious adverse events). Secondary outcome measures will consist of cerebrospinal fluid (CSF) biomarkers, cognition, and cerebral blood flow. ;
