Brief Summary:
This is a randomized, double-blind, sham-controlled, adaptive-design pivotal study of sensory stimulation in subjects with mild to moderate Alzheimer's disease. Approximately 345 subjects will be randomized to 12 months of daily treatment with either Active or Sham Sensory Stimulation Systems. Efficacy will be measured using the Alzheimer's Disease Cooperative Study- Activities of Daily Living (ADCS-ADL) assessment and a combined statistical test (CST) of the ADCS-ADL and the Mini-Mental State Exam (MMSE).

Detailed Description:

This is a multicenter, randomized, double-blind, sham-controlled, adaptive design pivotal study.

The objective of the study will be to assess efficacy of gamma sensory stimulation (visual and audio) in slowing disease progression versus Sham for subjects with mild to moderate AD as measured functionally by the Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL) assessment and a combined statistical test (CST) for ADCS-ADL and the Mini-Mental State Exam (MMSE). Secondary objectives will include measures of cognition and neuroanatomical change.

Three hundred and forty-five (345) Mild to Moderate Alzheimer's disease subjects (MMSE 15-26) will be recruited at up to 55 clinical sites in the United States and randomized in a 1:1 ratio (Treatment: Control). In the Treatment Group, subjects will be treated with the Active Sensory Stimulation System once daily. In the Control Group, subjects are treated with a Sham Sensory Stimulation System once daily. Daily treatment is planned for up to 12 months.

Subjects will attend study visits for informed consent, screening and baseline, then at 3-Months, 6-Months, 9-Months (by phone), 12-Months and 13-Months (for safety follow-up).

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 345 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Randomized, Double-blind, Sham-controlled, Adaptive-Design Pivotal Study of Sensory Stimulation in Subjects with Alzheimer's Disease
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description: This is a double-blind study; the investigator, the subject and study partner, and all other study personnel involved with subject assessments will remain blinded to the actual treatment assignment of the subjects. The Sponsor and their delegates involved in the study will be blinded to actual treatment assignment with the exception of technicians who are necessarily unblinded to assign and maintain the Investigational Devices and data analysis personnel as indicated in the Statistical Analysis Plan (SAP). Technicians and customer service agents who interact with subjects, their study partners and clinical sites will be specially trained to not reveal the study assignment (Active or Sham).
Primary Purpose: Treatment
