Treating Hyperexcitability in AD With Levetiracetam

Status Recruiting

Clinical Trial Summary

The aim of this study is to explore the relationship between cortical hyperexcitability, abnormalities of brain network function, and cognitive dysfunction in human patients with AD and whether administration of the antiepileptic medication levetiracetam (LEV) normalizes these measures and improves cognition.

Clinical Trial Description

This is a randomized, placebo-controlled crossover study. Participants with early Alzheimer's Disease (AD) will be tested in a double-blind crossover design with placebo, low-dose levetiracetam (LEV) 125 mg twice daily or high-dose LEV 500mg twice daily. These results will be contrasted with results from a demographically similar control group who will undergo baseline testing only, without any intervention, to establish a comparison norm for the AD group. Each subject will undergo four screening and baseline visits consisting of a baseline neurological, medical, and cognitive evaluation. If amyloid status is unknown in AD patients, the participant will have an amyloid PET scan. Additional baseline measures include: a high density electroencephalogram (EEG); a 24 hour ambulatory EEG; functional magnetic resonance imaging (fMRI); neuropsychological testing; and transcranial magnetic stimulation with electromyogram (EMG) and EEG measures to assess cortical excitability. AD participants will be randomized to one of six possible groups that consists of a varying order of 3 treatment periods (LEV 125 mg, LEV 500 mg and placebo). The group assignments will be counterbalanced across subjects. Each treatment period will last for 4 weeks with a 4 week washout between treatments. All participants will be assessed prior to initiation of a treatment period (with the initial assessment occurring as part of the baseline assessment) and at the end of each treatment period. The following measures will be repeated as done at baseline at these time points: fMRI; neuropsychological testing; and TMS-EMG-EEG. AD participants will be enrolled for approximately 5 months. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
