Who cannot take part

• Patients with known intracranial aneurism, with and/or unremovable coils, clips, shunts, intravascular stents, wafer, non resorbable dura substitute, or reservoirs

• Patients with any following prohibited treatments: • Any investigational medicinal product within 30 days prior to inclusion and during the study • Antibiotics with known neurotoxicity (eg, aminoglycosides, cephalosporin, quinolones), unless substitution is not possible, • Non-absorbable material (dura matter substitute, hemostatic agent…) • Any other drug according investigator to cause cerebral toxicity due to BBB opening • Contra-indications to temozolomide
• Implantation of the SC-9 not possible according to neurosurgeon (Any patient morphological characteristics (e.g. skin thickness >9mm), which, from neurosurgeons’ opinion, prevent implantation of the device or may impair the ability of the patient to receive treatment with SonoCloud, would be excluded); Contra indication Optune: If TTF treatment is initiated (only available in France), the investigator must first ensure that the patient has no contraindications to the Optune device (See page 41)
