A Randomized, Within-subject, Double-blind, Placebo-controlled Study Evaluating the Efficacy and Safety of AGB101 (Low-dose Levetiracetam, 220 mg, Extended Release Tablet) for the Treatment of Hippocampal Overactivity in the Elderly
Johns Hopkins University
Summary
This randomized, crossover, placebo controlled clinical study will assess the efficacy and safety of a slow release form of levetiracetam (AGB101) in the treatment of cognitively normal adults by measuring change in several imaging measures over the course of a two week treatment period.
Description
In clinical studies, the magnitude of hippocampal over-activity longitudinally predicts subsequent cognitive decline/conversion to dementia, and hippocampal over-activity in subjects with mild cognitive impairment (MCI) due to Alzheimer's disease (AD) is significantly correlated with the extent of neuronal injury affecting AD-specific regions of the brain. A previous study reported a significant correlation between greater hippocampal activation (fMRI) and more pronounced medial temporal lobe (MTL) atrophy (cortical thinning) indicative of AD-related neurodegeneration in subjects with MCI due…
