30The 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 with microbubble resonators. 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.
Carboplatin infusion on the day of Exablate BBBD procedure to treat cancerous cells in the brain
BBB opening via Exablate Neuro Type 2 system with microbubble resonators.
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.
