Study summary

The Overture Study is a randomized, controlled, single-blind multi-center clinical trial using the GammaSense Stimulation system to study safety, tolerability, and efficacy in people with mild to moderate cognitive impairment.

Read the detailed description

The Overture Study (CA-0005) is a Phase I/II randomized, controlled, single-blind multi-center clinical trial using the GammaSense Stimulation device to study safety, adherence rates and efficacy in subjects with mild to moderate cognitive impairment (MMSE 14-26) who are age 55 and older.

Subjects who pass screening will be randomized (ratio 2:1 Treatment to Control). Subjects and their caregivers will be blinded to their randomization group, as will key raters at each site. The device will be used for 60 minutes daily during the 6-month therapy phase, followed by a one month safety follow-up visit.

What researchers measure

Primary outcomes

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

    A widely accepted, validated measure of cognitive function in Alzheimer's Disease consisting of 14 questions that result in a score ranging from 0 to 90 with higher scores representing greater cognitive impairment

    Time frame: Quarterly over 6 months

Secondary outcomes

  1. Amyloid PET/CT

    Time frame: Quarterly over 6 months
