Brief Summary:

Recurrent glioblastoma (GBM) is a disease with high unmet clinical need. The standard of care for patients with GBM includes surgery, radiotherapy and chemotherapy. Despite this aggressive treatment, the overall median survival of patients with GBM remains at 15-20 months.

In more than 95% of cases, tumor recurrence is observed within 2 cm to 3 cm of the resection cavity within 4-7 months after initial treatments. One of the main causes of recurrence is the inability of chemotherapies to enter the brain from the systemic circulation due to the blood-brain barrier (BBB). The BBB is unique to cerebral blood vessels and blocks most drugs from entering the brain in sufficient concentrations.

The SonoCloud-9 (SC9) System delivers ultrasound to locally and transiently increase the permeability of the BBB to allow the passage of drugs into the cerebral parenchyma. The SC9 is dimensioned to cover the resection area and surrounding tissues in patients with recurrent GBM. The large sonicated volume covered by the SC9 device allows for broad BBB disruption and should allow for carboplatin chemotherapy to penetrate the surrounding tumor infiltrative area. By enhancing drug concentrations, it is hypothesized that further disease progression will be prevented.

Condition or disease Intervention/treatment Phase
Glioblastoma, Adult Device: SonoCloud-9 Drug: Carboplatin Phase 1 Phase 2

Detailed Description:
This will be an open-label, Phase 1/2a, multicenter, single-arm, interventional trial that will first evaluate the dose limiting toxicity (DLT) of escalating numbers of ultrasound beams at constant acoustic pressure using a standard escalation (Phase 1) and then confirm the safety and efficacy of BBB opening (Phase 2a expansion).

Drug Information available for: Carboplatin

Arm Intervention/treatment
Experimental: SonoCloud-9 Ultrasound + Carboplatin
SonoCloud-9 Carboplatin: 6 cycles (every 4 weeks)
Device: SonoCloud-9
Escalating numbers of ultrasound beams at constant acoustic pressure

Drug: Carboplatin
Dose of carboplatin infusion is AUC4-6

Primary Outcome Measures :
  1. Dose limiting toxicity (DLT) of number of activated ultrasound beams [ Time Frame: 15 days after the first sonication treatment ]
    DLT will be evaluated using imaging (MRI) and clinical examination, as CTCAE that occurs within 2 weeks of the first sonication and that does not respond to optimal medical management (including steroids) within 7 days.

  2. Blood-Brain Barrier (BBB) opening [ Time Frame: At the end of the first three sonication treatments (treatment occurs every 4 weeks) ]
    BBB opening will be evaluated by contrast-enhanced T1w magnetic resonance imaging (MRI)
