Study Summary
This trial is testing whether it's safe to break down the blood-brain barrier in people with glioblastoma who have had surgery and standard chemotherapy.
Who is the study for?
Adults aged 18-80 with a confirmed diagnosis of Grade IV glioblastoma, who have completed initial surgery and chemo-radiation without complications. Participants must be ready for maintenance chemotherapy, have a life expectancy of at least 3 months, good functional status (Karnofsky rating 70-100), stable health (ASA score 1-3), and able to communicate during the procedure.Check my eligibility
What is being tested?
The trial is testing the safety of using Focused Ultrasound to disrupt the blood-brain barrier in patients with glioblastoma post-surgery and standard treatment. The goal is to see if this can safely be done before they start maintenance chemotherapy.See study design
What are the potential side effects?
Potential side effects may include discomfort from lying still during the procedure, reactions to MRI contrast agents like gadolinium-DTPA or DEFINITY ultrasound contrast agent, and risks associated with disruption of the blood-brain barrier which could lead to brain swelling or other neurological issues.
