Overview
Brief Summary
The purpose of this study is to evaluate the safety and feasibility of the Exablate Model 4000 Type 2 system when used as a tool to open the blood-brain-barrier (BBB) in subjects with recurrent glioblastoma (rGBM) undergoing carboplatin monotherapy.
Detailed Description
This is a Phase 1/2, open-label, prospective, multi-center, single-arm study to establish the safety and feasibility of blood-brain-barrier disruption (BBBD) combined with intravenous carboplatin for the treatment of rGBM using the Exablate Neuro Model 4000 Type 2 system. Adult glioblastoma subjects that are planned for carboplatin chemotherapy will be considered for study enrollment. Eligible subjects will undergo up to 6 cycles of Exablate BBBD procedures in conjunction with carboplatin chemotherapy.

Arms & Interventions
Exablate BBBD with carboplatin
Carboplatin will be administered via IV infusion about every 4 weeks for up to 6 cycles. The dosage will be calculated based on subject's creatinine level. On the day of planned carboplatin therapy, subjects will undergo Exablate procedure to open the blood-brain-barrier in the targeted cancerous brain areas prior to carboplatin administration.
Intervention: Exablate BBBD

Outcomes
Primary Outcomes
Occurrence of Adverse Events
Time Frame: Through study completion, an average of 12 months
All adverse events and/or Serious Adverse Events will be documented and reported according to CTCAE criteria
Contrast intensity on MR imaging
Time Frame: Immediately after Exablate BBBD procedure
BBBD will be determined by contrast intensity in sonicated areas on T1 weighted gadolinium-based MR imaging
