What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 11 participants in total. It began in 2024-01-31 with a primary completion date of 2026-12.

Brief Summary

Patients diagnosed with glioblastoma (GBM) are faced with limited treatment options. This pilot study will evaluate the safety and feasibility of combining an investigational drug called 5-ALA with neuronavigation-guided low-intensity focused ultrasound (LIFU) for patients who have recurrent GBM. Focused ultrasound (FUS) can be used to non-invasively destroy tumor tissue while preserving normal tissue. When FUS is combined with 5-ALA, this combinatorial approach is called sonodynamic therapy (SDT), and this investigational therapy is being tested for its ability to cause damage to GBM cells. SDT will take place prior to surgery for recurrent GBM.

Eligibility Criteria

Inclusion Criteria: 1. Disease status and Disease Parameters: * Suspected recurrent glioblastoma that is clearly measurable based on the modified Response Assessment in Neuro-Oncology (RANO) criteria * The tumor lesion needs to comprise at least 1 contrast-enhancing lesion with a volume of ≥ 2 cm3 and ≤ 20 cm3 of targeted treatment area * Tumor tissue to be treated is in a surgically accessible brain region for resection * The brain tumor to be treated must be in the treatment envelope of the NaviFUS system (30 mm to 90 mm from the inner skull table) * Recurrence will be assessed by imaging and confirmed by consensus at tumor board 2. Men or women between the ages of 18-80 years of age at the time of consent 3. No contraindication to repeat brain surgery 4. Karnofsky Performance Score of 70-100 5. Able to undergo an MRI with contrast 6. Able to swallow oral medications 7. Willingness and ability to comply with scheduled visits, treatment plans, lifestyle considerations, laboratory tests, and other procedures. 8. Ability to understand and the willingness to sign a written informed consent document (personally or by the legally authorized representative, if applicable). 9. Participants who received prior chemotherapy, radiation therapy, immunotherapy, and/or another investigational therapy must have recovered (Common Terminology Criteria for Adverse Events \[CTCAE\] Grade ≤1 or baseline) from the acute effects of the therapy or therapies) except for residual alopecia or Grade 2 peripheral neuropathy prior to registration. 10. Has adequate bone marrow and organ function as defined by the following laboratory values (as assessed by the local laboratory for eligibility): Hematological * Absolute neutrophil count (ANC) ≥1000/mm3 * Platelets ≥ 100,000/mm3 * Hemoglobin ≥ 11 g/dL for women and ≥ 12 g/dL for men Participants may receive erythrocyte transfusions to achieve this hemoglobin level at the discretion of the investigator. * INR ≤ 1.4 Renal \& Hepatic * Creatinine clearance CrCl ≥ 60 mL/min/1.73 m2 as estimated by the Cockcroft-Gault (C-G) equation. If estimated CrCl is abnormal, accurate measurement should be obtained by 24- hour CrCl. * Bilirubin ≤ 1.5 x ULN (except in patients with Gilbert's disease, where bilirubin to 2.0x ULN is allowed). * AST and ALT ≤ 3 x ULN * Alkaline phosphatase ≤ 3 x ULN * Estimated glomerular filtration rate ≥30mL/min/1.73m2 Exclusion Criteria: 1. Known sensitivity or allergy to 5-ALA 2. Simultaneous use of other potentially phototoxic substances (e.g. tetracyclines, sulfonamides, fluoroquinolones, hypericin extracts) 3. Diagnosis of porphyria 4. Hypersensitivity against porphyrins 5. Pregnancy 6. Significant cardiac disease or coagulopathy 7. Herniation / intractable seizure / other clinical indications requiring urgent resection 8. Known active systemic bacterial infection (requiring intravenous \[IV\] antibiotics at time of initiating study treatment), fungal infection, or detectable viral infection (such as known human immunodeficiency virus positivity or with known active hepatitis B or C (for example, hepatitis B surface antigen positive) 9. Have had a recent (≤3 months prior to registration) transient ischemic attack or stroke 10. Significant vascular disease (e.g. aortic aneurysm) 11. Evidence of bleeding diathesis or coagulopathy 12. Need for systemic anticoagulation which cannot be held for 7 days prior to SDT 13.

Serious and inadequately controlled cardiac arrhythmia 17. Acute exacerbation of chronic obstructive pulmonary disease 18. Has serious and/or uncontrolled preexisting medical condition(s) that, in the judgment of the investigator, would preclude participation in this study 19. Treatment with another investigational drug or investigational procedure within 30 days prior to registration or within 5 half-lives of the investigational product, whichever is longer 20. Brain edema and/or mass effect that causes midline shift of more than 15 mm 21. Evidence of recent (within 30 days prior to registration) intracranial hemorrhage 22. Calcifications or metallic implanted objects in the focused ultrasound sonication path 23. Scalp atrophy or scars at the expected location of transducer 24. Cerebral or systemic vasculopathy 25.
