Exablate Blood-Brain Barrier Disruption With Carboplatin for the Treatment of rGBM

Assessment of Safety and Feasibility of Exablate Blood-Brain Barrier Disruption (BBBD) With Microbubbles for the Treatment of Recurrent Glioblastoma (rGBM) in Subjects Undergoing Carboplatin Monotherapy

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.

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.
