April 15, 2026 updated by: InSightec

Assessment of Safety and Feasibility of Exablate Blood-Brain Barrier Disruption for the Treatment of High-Grade Glioma in Patients Undergoing Standard Chemotherapy

The purpose of this study is to evaluate the safety of the Exablate Model 4000 Type 2.0 used as a tool to disrupt the BBB in patients with high grade glioma undergoing standard of care therapy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The primary objective is to evaluate the safety and feasibility of BBB disruption using the Exablate Type 2.0 system in adult patients with glioblastoma (GBM) undergoing adjuvant TMZ chemotherapy, which occurs following maximal safe surgical resection and completion of the initial concurrent radiation-chemotherapy in accordance with the current standard of care

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Focused Ultrasound (FUS) BBB Disruption
The Exablate Model 4000 Type 2.0 system is intended for use as a tool to induce localized and temporary blood-brain barrier disruption in patients with glioblastoma undergoing standard of care chemotherapy.
Device: Magnetic Resonance guided Focused ultrasound (MRgFUS)
FUS involves the application of acoustic energy at low frequencies from over 1000 individual transducers into distinct body targets.
Other Names:
  • Exablate Neuro

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Device and procedure related adverse events
Time Frame: Throughout the study, approximately 12 months.
The number and severity of device and BBB disruption procedure related adverse events will be evaluated and classified according to the CTCAE
Throughout the study, approximately 12 months.
Feasibility of repeated BBB disruption will be evaluated through assessment of post-procedure contrast-enhanced magnetic resonance (MR) imaging
Time Frame: At the time of each ExAblate MRgFUS procedure]
The repeatability of BBB disruption will be evaluated at each of the 6 procedures and will be evaluated through assessment of post-procedure contrast-enhanced MR imaging.
At the time of each ExAblate MRgFUS procedure]

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
