Resumen
Fecha de inicio: 8 de noviembre de 2024
Fecha en la que se inscribió al primer participante.Este ensayo clínico está diseñado para investigar un nuevo enfoque de tratamiento para pacientes con glioblastoma multiforme recurrente (rGBM), un tipo de cáncer cerebral que ha reaparecido después del tratamiento inicial con radioterapia y quimioterapia con temozolomida. El estudio tiene como objetivo determinar si la combinación de un fármaco llamado Bevacizumab con una tecnología conocida como el Sistema NaviFUS es más efectiva que el uso de Bevacizumab solo. El glioblastoma es un cáncer difícil de tratar, y encontrar terapias más efectivas podría mejorar significativamente los resultados para los pacientes. Los participantes en este estudio serán divididos aleatoriamente en dos grupos. Un grupo recibirá el tratamiento estándar de Bevacizumab a través de una infusión intravenosa. El otro grupo recibirá el mismo tratamiento con Bevacizumab, pero con la adición del tratamiento con FUS mediado por microburbujas utilizando el Sistema NaviFUS. Esto implica un procedimiento basado en ultrasonido diseñado para mejorar la entrega del fármaco al tumor cerebral. El tratamiento continuará cada dos semanas hasta un máximo de 34 semanas, a menos que la enfermedad progrese, ocurran efectos secundarios inaceptables o el participante elija retirarse. El estudio monitoreará la seguridad y eficacia de los tratamientos observando de cerca las respuestas y efectos secundarios de los pacientes.

Criterios
Inclusion Criteria: 1. Male or female patients ≥ 18 years of age at the time of study enrollment. 2. Body mass index (BMI) ≥ 17 kg/m2. 3. Patients diagnosed with glioblastoma must have unequivocal evidence of recurrence, as determined by contrast-enhanced magnetic resonance imaging (CE-MRI), following prior radiotherapy and temozolomide chemotherapy. 4. Patients may have undergone surgery for recurrence. The patients should have completed surgery and adequately recovered prior to the time of study enrollment. 5. Patients must have radiographic evidence of either at least an 80% resection of enhancing tumor following recurrence or a maximal measurable residual tumor ≤ 20 cm3. 6. If patients are receiving corticosteroids, they must have been on a stable or decreasing dose of corticosteroids for at least 1 week prior to the planned first treatment. 7. At the time of study enrollment, the minimum interval since the last event: * 4 weeks out from invasive procedures (e.g., open biopsy, surgical resection, significant traumatic injury, or any other major surgery involving entry into a body cavity) and the patient must have recovered from the effects of surgery * 1 week out from minor surgical procedures or core biopsies 8. 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. Patients should have a life expectancy ≥ 12 weeks. 10. Patients must have Karnofsky Performance Status (KPS) ≥ 70. 11. Adequate hematopoietic, renal, hepatic, and coagulation function, defined as: * Hemoglobin ≥ 10 g/dL * Platelets ≥ 100,000/mm3 * Neutrophils ≥ 1,500/mm3 * Serum creatinine ≤ 1.5 × upper limit of normal (ULN) * Urine protein creatinine ratio (UPCR) \< 1 or urine dipstick for proteinuria ≤ 2+ * Alanine aminotransferase (ALT) \< 3 × ULN * Aspartate aminotransferase (AST) \< 3 × ULN * Total bilirubin (TBL) \< 2 × ULN * Prothrombin time ≤ 1.5 x ULN * International Normalized Ratio (INR) \< 1.5 These tests must be conducted within 2 weeks prior to the planned first treatment. 12. The central of FUS exposure region is located 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 if assigned to treatment group. 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. Informed consent should also be given for biological materials and diagnostic imaging to be stored and used for future research on brain tumors. 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. Uncontrolled or significant cardiovascular disease, including any of the following: * New York Heart Association (NYHA) Grade II or above congestive heart failure (CHF) within 12 months prior to study enrollment * Unstable angina pectoris * Medical history of myocardial infarction within 6 months prior to study enrollment * Cardiac shunt 6. Stroke (except for transient ischemic attack; TIA) within 6 months prior to study enrollment. 7. Patients with implanted electronic device, for example, implanted cardioverter-defibrillator (ICD), cardiac pacemaker, permanent medication pumps, cochlear implants, responsive neurostimulator (RNS), deep brain stimulation (DBS), or other electronic devices implanted in the brain. Patients with contraindications for MRI as judged by Investigator, including non-MRI compatible metallic implant(s). 8. Patients with inadequately controlled hypertension, defined as systolic blood pressure \> 150 mmHg and/or diastolic blood pressure \> 100 mmHg while on medication, within 2 weeks prior to first treatment. 9. Patients with evidence of any thrombotic or hemorrhagic events, including but not limited to: * Inherited bleeding diathesis or significant coagulopathy with the risk of bleeding (i.e., in the absence of therapeutic anticoagulation). * History of pulmonary haemorrhage/haemoptysis ≥ grade 2 according to the CTCAE version 5.0 criteria within 1 month prior to study enrollment * Arterial or venous thrombosis (e.g., pulmonary embolism) within 3 months prior to study enrollment 10. Patients with unstable pulmonary disease or chronic obstructive pulmonary disease (COPD) exacerbation or other respiratory illness requiring hospitalization or precluding study therapy at the time of study enrollment. 11. Patients who have psychiatric illness/social situations that would limit compliance with study requirements. 12. Known HIV-positive patient, however, that HIV testing is not required for entry into this study. 13.

Known sensitivity/allergy to Magnetic Resonance Imaging (MRI) contrast agents, Computer Tomography (CT) contrast agents, SonoVue®, Bevacizumab, or any of their components. 17.
