About this study

Official title: Multi-Center Study of Tolerability, Safety and Efficacy of Sensory Stimulation at Multiple Dose Levels to Improve Brain Function (Etude Study)

The Etude Study is a multi-center, four-arm prospective dose-adjusting study designed to assess the tolerability, safety and efficacy of non-invasive sensory stimulation for patients with cognitive impairment.

Read the detailed description

Subjects will be enrolled in two Cohorts (N=10 each, enrolled sequentially), and each will assess two different dose levels (randomly assigned). Based on initial outcomes in Cohort 1 at Interim Analysis, the doses for Cohort 2 will be escalated or decreased. Subjects will participate in 1 year (48 weeks) of daily therapy dose using the non-invasive, non-significant risk sensory stimulation medical device.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Amyloid Positron Emission Tomography (PET) Scan

    Movement of amyloid, as measured qualitatively and quantitatively in Amyloid PET Imaging at 0, 1.5, 3, 6, 9 and 12 months following assigned regimen of sensory stimulation treatment sessions

    Measured: PET Imaging at Baseline, 6 weeks and every 3 months throughout therapy (0, 1.5, 3, 6, 9 and 12 month)

  2. Adverse Events

    Composite adverse events to be assessed at Interim Analysis (at any point in partial study completion), and final analysis (at 6 and 12 months time points).

    Measured: Over 12 months

Secondary outcomes (1)
  1. Alzheimer's Disease Assessment Scale- Cognitive Subscale (ADAS-Cog)

    A scale used to assess cognition; This scale consists of 14 questions assessed resulting in a score from 0 to 90, where a higher score indicates more cognitive disruption.

    Measured: Baseline, 3, 6, 9 and 12 months

Questions about this trial

What is this clinical trial studying?

A study testing GammaSense Stimulation System (non-invasive, non-significant risk) in people with Alzheimer Disease, Early Onset and Alzheimer Disease, run by Cognito Therapeutics, Inc. at 1 site 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 5 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 24 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

Results are not available in the source record.

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?

Change in Amyloid Positron Emission Tomography (PET) Scan (time frame: PET Imaging at Baseline, 6 weeks and every 3 months throughout therapy (0, 1.5, 3, 6, 9 and 12 month)). The study lists 2 primary outcomes in all. 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 24 Aug 2021.
