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.

Critères

Tous
Inclusion Criteria:

embryonal tumor including ATRT, ependymoma)

- recurrence or progression of brain tumor after at least a first line of standard
treatment (multifocal tumors and metastatic disease allowed)

- indication of treatment with carboplatin, validated in multidisciplinary meeting

- Karnofsky performance scale index (patients ≥ 16 years old) or Lansky performance
status (patients < 16 years old) > 50% (a patient with a performance status score
altered by a motor deficit due to tumor infiltration will be allowed to be included)

normal

- serum creatinin < 1.5x upper limit of normal for the age or creatinine clairance
>70mL/min/1.73m2 (EDTA method or 24h urine)

- coagulation parameters in the normal limits for age (fibrinogen, prothrombin time
and activated clotting time)

- no grade 2 or more toxicity depending on the NCI-CTCAE v5.0 criteria

- no healed wound on the scalp

- covered by health insurance

- for patients of chilbearing age (15-17 years old) : a negative pregnancy test and an
efficient method of birth control

- written consent signed by the patient (if possible) and his parents or legal
representatives.



- weight <15kg

- antineoplastic treatment other than carboplatin taken at the same time or stopped
since less than:

- 6 weeks for nitrosoureas

- 1 month for bevacizumab

- 5 half-lives for tyrosin kinase inhibitors

- 3 weeks for any other chemotherapy

for the first sonication session

- radiotherapy during the last 6 weeks

- any other cancer treated during the last 5 years

- any other uncontrolled disease or active infection

- any other co-morbidity that could compromise participation to the study (in the
judgement of the clinical investigator)

- any anatomical particularity (skull thickness, thin skin) that could compromise a
safe implantation of the device and/or compromise the quality of the treatment (in
the judgement of the clinical investigator)

- implanted defibrillator/pacemaker, neurostimulator, cochlear implant, intracerebral
ferromagnetic vascular clip

reasons

- pregnant and lactating women

- contemporaneous treatment by anticoagulant or platelet aggregation inhibiting drugs

- contemporaneous treatment possibly toxic for the central nervous system. The
following treatments are excluded if taken less than 5 half-lives before the
ultrasound session (unknown toxicity in case of BBB disruption) :

- anticoagulant

- any contemporaneous treatment that, in the judgement of the clinical investigator,
could induce brain toxicity after BBB disruption
