An interventional study of ExAblate 4000 System in Benign Centrally-Located Intracranial Tumors, sponsored by InSightec. Recruiting at 3 sites in United States. Open to participants aged 5 Years to 22 Years. Per ClinicalTrials.gov, last updated 2026-06-29.
Sponsored by InSightec · Not applicable, Interventional, and Treatment
The goal of this prospective, non-randomized, single-arm, feasibility study is to develop data to evaluate the safety and feasibility of ExAblate 4000 treatment of benign intracranial tumors which require clinical intervention in pediatric and young adult subjects.
Indication of Use: Ablation of benign intracranial tumors in children and young adults which are ExAblate accessible.

Indication of Use: Ablation of benign intracranial tumors in children and young adults which are ExAblate accessible.
This is a feasibility study intended to collect data for use in the development of future studies. As such, no formal statistical hypothesis or hypothesis testing is proposed. The purpose of this study is to evaluate the safety and feasibility of managing benign brain tumor size using ExAblate 4000 treatment of progressing benign intracranial tumors which require clinical intervention in pediatric and young adult subjects.
InSightec is the lead sponsor of 84 studies on the registry; 9 are open to participants now.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Measurement of Tumor Volume
ExAblate procedure will demonstrate feasibility along with measurement of tumor volumes at follow-up as compared to the baseline MRI.

Changes in the General Physical Exam
Any changes in physical examination performed by a physician.
Time frame: Baseline through 12 Month Follow Up
Changes in the Neurological Exam
Any changes in neurological examination performed by the neurologist/neurosurgeon.
Time frame: Baseline through 12 Month Follow Up
Confrontational Visual Field Testing
Changes in confrontational visual field testing performed by a physician
Time frame: Baseline through 3 Month Follow Up
