Adjuvant Temozolomide ± 5-Aminolevulinic Acid + Low Intensity Diffuse Ultrasound Sonodynamic Therapy System for Newly Diagnosed Glioblastoma

Who cannot join

• Any component of the tumor in the infratentorial location (cerebellar or brainstem tumors are excluded)
• Bihemispheric disease or tumors that involve the bilateral corpus callosum, or disease burden involving the brain stem or cerebellum based on MRI post-gadolinium enhancement,
• Multi- centric disease (enhancing or non-enhancing) or multi-focal disease (defined as 2 separate areas of contrast enhancement measuring at least 1 cm that are not contiguous and cannot be encompassed in sonication field on either fluid-attenuated inversion recovery (FLAIR) or T2 hyperintensity.
• Leptomeningeal disease
• 6. A diagnosis of glioscarcoma by histopathology Intent to undergo treatment with the tumor treating fields (TTF) at any time during the study, use prior to screening is permitted.
• 7. Corticosteroid use > 4 mg/day of dexamethasone (or equivalent), steroid dose should be stable or decreasing for ≥1 week prior to randomization 8. Inability to undergo MRI or receive gadolinium (Gd)-based contrast agents 9. Hypersensitivity to 5-ALA or porphyrins 10. Patient head size > 16.6 cm in breadth (max width of head, above the ears) and > 21.3 cm in length (front to back) to ensure fit within the helmet transducer array. 11. Skull voids/defects > 10 mm diameter if defect is open, or > 14 mm if defect is covered with titanium burr hole cover, titanium mesh, or similar repair hardware. Note, Longeviti Neuro Solutions or other sonolucent implants should be treated as open defects and therefore may not exceed 10 mm in diameter. 12. Hemorrhagic or ischemic stroke (including transient ischemic attacks) and central nervous system bleeding in the preceding 6 months that are not related to glioma surgery. History of prior intratumoral bleeding prior to screening is not an exclusion criterion; however, patients with a history of prior intratumoral or intracranial bleeding will undergo a non-contrast head CT to exclude acute bleeding. 13. Has any history of glioma, a concurrent malignancy, or malignancy within 3 years of randomization, unless definitive therapy is completed, with the exception of basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the cervix or breast that has completed curative therapy 14. Patients who have clinically significant cerebral edema requiring urgent intervention (e.g., surgery, initiation of steroids, escalating doses of steroids). 15. Patients with rapid clinical deterioration that, in the opinion of the investigator, is likely to worsen during the first cycle of treatment. 16. Any prior treatment for glioma, aside from surgical resection, and chemoradiation with TMZ. TTF is permitted prior to study entry. Agents used for diagnosis, imaging or visualization, even if investigational, are not exclusionary. Exclusionary treatments would include, but are not limited to: A. Stereotactic radiosurgery B. Placement of Gliadel® (carmustine; BCNU) wafers C. Any other intratumoral or intracavity treatment, D. Receipt of other chemotherapies, bevacizumab, immunotherapy (including vaccine) or investigational agents. 17. Acute or chronic types of porphyria. 18. Gastrointestinal disorder that negatively affects absorption. 19. Known active hepatitis B or C (Note: testing is not required). 20. Known human immunodeficiency virus (HIV) infection (Note: testing is not required). 21. Participation in another interventional clinical trial for GBM. (Observational studies are allowable) 22. Unable to avoid phototoxic drugs (e.g., St. John's wort, griseofulvin, thiazide diuretics, sulfonylureas, phenothiazines, sulfonamides, quinolones, and tetracyclines) for 24 hours prior to and following 5- ALA administration. 23. Any other concurrent severe or uncontrolled concomitant medical condition that could compromise participation in the study (e.g., clinically significant pulmonary disease, cardiac disease, clinically significant psychiatric or neurological disorder, active or uncontrolled infection). 24. Women who are pregnant or breastfeeding 25. Patients with a condition the Investigator believes would interfere with the ability to provide informed consent or comply with study instructions, or that might confound the interpretation of the study results or put the patient at undue risk.
