Preliminary Clinical Feasibility Study of a Medical Device Enabling Brain Access Using Microbubble-Enhanced Sonication
France6 participantsStarted 2026-09
Plain-language summary
CAMPSIS is a preliminary feasibility study of the TheraOne medical device (IIb). TheraOne is an active, non-invasive medical device intended to deliver transcranial FUS in combination with intravenous microbubbles in order to transiently and locally induce the BBB permeability.
This study aims to evaluate the safety of cerebral sonication (TheraOne) in the management of patients with recurrent grade 4 glioma (wild-type IDH, technically resectable) or brain metastases originating from an extracranial solid tumor.
Patients enrolled in the study will undergo a single sonication session during a protocol visit and will be monitored for up to 30 days after the sonication through the various scheduled protocol visits.
Blood samples will be collected at the start of the study, during the sonication, and during the post-sonication follow-up visit for all patients enrolled in the study.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
. Patient with an expansive intra-cerebral tumor showing enhancement after gadolinium injection on MRI (T1-weighted images, with and without gadolinium contrast).
. Tumor radiologically classified as:
. In the case of brain metastases, multifocal disease is allowed, provided that additional metastases are smaller to 20 mm, not neurologically threatening, and do not require surgery. Cases of leptomeningeal invasion are not allowed.
. Tumor should not exhibit signs of rapid progression or acute neurological compromise requiring urgent intervention. Rapid progression is defined as a ≥25% increase in contrast-enhancing tumor volume within 4 weeks, associated with mass effect or new edema. Acute neurological compromise includes any newly developed or worsening neurological deficit (e.g., motor weakness, aphasia), seizures refractory to antiepileptics, decreased level of consciousness (Glasgow Coma Scale (GCS) \<13), or signs of intracranial hypertension.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
