A Phase IIa Study to Evaluate the Safety and Efficacy of Blood-Brain Barrier (BBB) Opening Using Transcranial MR-Guided Focused Ultrasound in Patients With 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 open the blood-brain barrier (BBB) in patients with probable Alzheimer's Disease (AD).
This study is a prospective, open label, single-arm, non-randomized, phase IIa trial to evaluate the feasibility, safety and efficacy of repeated, BBB opening using the ExAblate® Model 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 a single center in Canada and will enroll up to 30 patients.
