About this study

The proposed study is designed to evaluate the performance of the COGNISION™ System as a tool to assist physicians in diagnosing Alzheimer's Disease (AD) in real-world clinical settings. The design of this study is guided by two overriding factors: 1) to optimize the performance of the event related potentials (ERP) classifiers, the subjects making up the training sets must be well characterized as to their clinical diagnosis, and 2) all ERP tests must be performed and reproduced in real-world clinical settings.

Read the detailed description

The study will be :

  1. Multi-Center Study: primary goal of this study will be to evaluate the COGNISION™ Platform across multiple study locations. This will demonstrate an ability to perform tests, collect data, and generate classifications irrespective of variations in testing locations and personnel.
  2. 5-8 study sites will be selected with each site being a recognized NIH Center of Excellence for Alzheimer's disease or other nationally recognized Alzheimer's disease research center.
  3. Each site will evaluate up to 60 subjects evenly divided between AD patients and age-matched controls (while the prevalence of AD is approximately 2% in the general population, the ratio of AD to normal among those who visit a clinic for memory or cognitive related issues is between 50-60%).
  4. Each site will follow the same testing protocols.
  5. All test data will be uploaded to the online COGNISION™ database server.

Questions about this trial

What is this clinical trial studying?

An observational study of Memory Disorders and Alzheimer Disease, run by Neuronetrix, Inc. at 7 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Mar 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Electrophysiological markers of cognitive status (time frame: Markers are collected at study visit). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Mar 2014.
