Safety and Feasibility of Exablate Blood-Brain Barrier Disruption for Mild Cognitive Impairment or Mild Alzheimer’s Disease Undergoing Standard of Care Monoclonal Antibody (mAb) Therapy

Description

The primary objectives of this study is to evaluate the safety and feasibility of BBBO (blood-brain barrier opening) using the Exablate Model 4000 Type 2 in the setting of standard aducanumab or lecanemab therapy among patients with mild cognitive impairment (MCI) or mild Alzheimer’s disease (AD) with confirmed β-amyloid, who are eligible for aducanumab or lecanemab infusion therapy, and to also evaluate the safety of the BBO procedure through patient examination (neurological and cognitive/behavioral) and MRI assessments during the treatment and follow-up.

The secondary objectives of this study is to determine the effect of BBBO in patients with MCI or mild AD treated with aducanumab or lecanemab on brain β-amyloid plaque measured by amyloid positron emission tomography (PET), as well as to assess the clinical impact of BBBO with standard aducanumab or lecanemab therapy, if any, as assessed with ADAS Cog 11 and MMSE over time following BBBO.
