Study summary

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 researchers measure

Primary outcomes

  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

    Time frame: 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).

    Time frame: Over 12 months

Secondary outcomes

  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.

    Time frame: Baseline, 3, 6, 9 and 12 months
