Phase I Trial Assessing the Safety of the Repeated Ultrasound-induced Opening of the Blood-brain Barrier in Pediatric Patients With Refractory Supra-tentorial Malignant Brain Tumors Before Chemotherapy Administration

Purpose : the aim of this study is to assess the feasibility and safety of
ultrasound-induced opening of the blood-brain barrier (BBB) with the SonoCloud-9
implantable ultrasound device in pediatric patients treated for a recurrent malignant
supra-tentorial brain tumor treated with carboplatin.
Study hypothesis : the blood-brain barrier can be transiently and safely opened with
pulsed low intensity ultrasound immediately prior to intravenously delivered
chemotherapy. The opening of the BBB with the SonoCloud-9 system will increase the tumor
exposure to carboplatin and increase progression-free and overall survival in pediatric
patients treated for a recurrent malignant supra-tentorial brain tumor.
