About
This is a randomized, double-blind, sham-controlled pivotal study of sensory stimulation in subjects with mild to moderate AD. Up to approximately 670 subjects will be treated with either Active or Sham investigational device, Spectris™ AD, for 60 minutes daily for approximately 12 months. Efficacy will be measured using the Integrated Alzheimer's Disease Mini-Mental State Exam (MMSE) Activities of Daily Living (ADCS-ADL) Rating Scale (iADMARS).
Full description
This is a multicenter, randomized, double-blind, sham-controlled pivotal study.
The objective of this study is to assess the safety and efficacy of gamma sensory stimulation (visual and audio) via Spectris ™ AD in slowing cognitive-functional symptom worsening versus the Sham device for subjects with mild to moderate AD as measured by changes in function and cognition.
Up to approximately six hundred and seventy (670) subjects with Mild to Moderate AD (MMSE 15-28) will be recruited at up to 70 clinical sites in the United States and randomized in a 1:1 ratio (Active : Sham). In the Active Group, subjects will be treated with the Active Spectris™ AD for 60 minutes daily. In the Sham Group, subjects are treated with a Sham Spectris™ AD for 60 minutes daily. Daily treatment is planned for approximately 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).
Some clinical sites will be included in a substudy evaluating additional fluid biomarkers. Select subjects enrolled at these sites will undergo a lumbar puncture to collect cerebrospinal fluid (CSF) at Baseline, 3 Months, and 12 Months.
