ExAblate Blood-Brain Barrier (BBB) Disruption for the Treatment of Alzheimer's Disease
March 4, 2024 updated by: InSightec
Assessment of Safety and Efficacy of ExAblate Blood-Brain Barrier Disruption for the Treatment of Patients With Probable Alzheimer's Disease
The purpose of this study is to evaluate the safety and efficacy of the ExAblate Model 4000 Type 2.0 System as a tool to disrupt the blood-brain barrier (BBB) in patients with probable Alzheimer's Disease (AD).

Detailed Description
This is a prospective, multi-center, single-arm study to evaluate the safety and efficacy of BBB disruption using the ExAblate Model 4000 Type 2.0 (220 kHz) system.
Patients with diagnosis of Probable Alzheimer's Disease may qualify for a clinical trial to have three serial ExAblate BBB disruption procedures in specific areas in the brain.
This study will be conducted at up to 8 sites in the United States and will enroll up to 30 patients.
