Brief summary: Glioblastoma (GBM) is an aggressive cancer with a progression-free survival (PFS) of 7 months and an overall survival (OS) of 15 months. Many therapeutic approaches have failed to improve the prognosis of patients to date. One of the main reasons is the presence of blood brain barrier (BBB) which limits therapeutic agents uptake in the brain. GBM is also considered to have a "cold" (unresponsive) immunological microenvironment due to factors released by the tumor and the presence of BBB limiting the transit of immune cells from the systemic circulation. Therefore, by-passing the BBB appears as a promising strategy.

The objective of the Phase II clinical trial, SonoFIRST, is to evaluate if the use of therapeutic ultrasound device, sonoCloud-9 (SC9) could improve the progression free survival of newly diagnosed GBM patients, treated by concurrent temoradiation and adjuvant temozolomide. The transient opening of the BBB by ultrasound with the SonoCloud-9 (SC9) device, predicts the increase in the penetration of temozolomide (TMZ) into the brain and the stimulation of cerebral immunity with the prospect of improving the survival of 160,000 new brain tumor patients each year in Europe and the United States.

Detailed description: This will be an open-label, Phase 2, multicenter, double arm, randomized, interventional trial that will evaluate primarily the clinical efficacy of the device and will be to compare Progression Free Survival (PFS) between the standard of care treatment with concomitant ultrasound BBB opening versus standard of care alone. Glioblastoma (GBM) is the most common and aggressive primary brain cancer. Currently, prognosis is very poor, with a survival of about 15 months with current therapies. Although intensive treatments combining surgery, radiotherapy and chemotherapy, the prognosis of GBM patients remains poor. New treatment strategies are urgently needed.

In the brain, the presence of the blood-brain barrier (BBB) limits the uptake of therapeutic agents. To encounter this BBB issue, Professor Alexandre Carpentier and his team developed an ultrasound medical device (SonoCloud), implanted in the skull during surgery. This highly innovative technique temporarily permeates the BBB, increasing drug delivery to the brain by five times. The SonoCloud, a low-intensity pulsed ultrasound device developed by CarThera, is one of the major innovations in this field, as shown by the encouraging results obtained in studies in recurrent GBM.

The expected benefits of using the SonoCloud-9 experimental device prior to TMZ chemotherapy are the stabilization or reduction of GBM tumor volume on the one hand, and stabilization or improvement of the patient's neurological status on the other hand.

Participation in the clinical trial will contribute to a better understanding of the safety and efficacy of opening the BBB. It will be possible to determine whether the BBB opening using low-intensity pulsed ultrasound can be effective in treating GBM, in addition to the standard of care protocol.
