Brief summary
This will be a prospective, open-label, single-arm pilot study to investigate the safety and efficacy of Bevacizumab (BEV) in combination with microbubble (MB)-mediated FUS in patients with recurrent GBM. BEV represents the physician's best choice for the standard of care (SoC) in rGBM after previous treatment with surgery (if appropriate), standard radiotherapy with temozolomide chemotherapy, and with adjuvant temozolomide.
Detailed description
The study aims to demonstrate the high safety profile and effectiveness of BEV+FUS-MB targeted therapy for brain tumors. Any patient with a histological diagnosis of GBM who meets all of the specific eligibility criteria may participate in this study by signing informed consent in person or through their legal representative. Eligible patients will undergo a 2-week baseline observation screening period. Up to 10 eligible patients will be enrolled in this study. Eligible patients will follow the standard operating procedures of BEV (10 mg/kg intravenous (IV) infusion over 30-90 minutes). After at least 30 minutes, patients will be administered microbubbles (MB) (Lumason®) at a dose of 0.1 mL/kg, along with optimal ultrasound exposure doses determined by the acoustic emission feedback FUS power control algorithm of the NaviFUS System. The treatment will be administered every 2 weeks up to 34 weeks or until evidence of progression disease (PD), intolerable toxicity precluding further treatment, non-compliance with study follow-up, or withdrawal of consent, whichever occurs first.

Patients must have recovered from the toxic effects of prior therapy at the time of study enrollment as follows: * 4 weeks out from any investigational drug or device * 4 weeks out from chemotherapy * 6 weeks since the completion of a nitrosourea-containing chemotherapy regimen (e.g., Carmustine (BCNU)) * 12 weeks out from completion of radiotherapy 9.

The central of FUS exposure region is located close to the cortex, with a minimum distance of at least 30 mm beneath the skull bone. 13. Females of childbearing potential must have a negative pregnancy test documented within 2 weeks prior to first treatment. Females of childbearing potential and male patients with partners of childbearing potential must agree to adhere to an acceptable method of contraception (as outlined below) from prior to the first study treatment until at least 6 months after the completion of last treatment. Standard acceptable methods of contraception include the use of highly effective methods such as hormonal contraception, diaphragm, cervical cap, vaginal sponge, condom, spermicide, vasectomy, intrauterine device, or abstinence from sexual activity. 14. Patients are able and willing to have peripheral intravenous (IV) line placement of Bevacizumab and are able to have hair shaved (either whole head or in the region where the coupling membrane will touch) prior to FUS treatment. 15. Patients or their legal representatives are able to provide written informed consent for participation in the trial and patients are willing to comply the procedures (i.e., study-related assessments), instructions, and restrictions outlined in this study in the duration of the study.
Exclusion criteria
1. Patients who have radiographic evidence of multifocal enhancing tumors. 2. Patients who have undergone previous treatment with anti-angiogenic therapy, including Bevacizumab, or other VEGF inhibitors or VEGF-receptor signaling inhibitors. 3. Patients who have previously received Carmustine wafers implantation during re-operation. 4. Patients who have previously received or are currently undergoing tumor treating fields (TTF) treatment. 5.
