Safety, Feasibility, and Efficacy of Non-invasive Vagus Nerve Stimulation (nVNS) in the Treatment of Aneurysmal Subarachnoid Hemorrhage
United States25 participantsStarted 2022-10-04
Plain-language summary
This is a single-site, single-arm, open-label pilot study assessing the safety, feasibility, and efficacy of non-invasive vagus nerve stimulation (nVNS), gammaCore, for the acute treatment of aneurysmal subarachnoid hemorrhage (SAH) subjects in a neurocritical care setting. 25 patients will be enrolled, all treated with an active device. The primary efficacy outcomes are reduced aneurysm rupture rate, reduced seizure and seizure-spectrum activity, minimized hemorrhage grades, and increased survival.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Male or female, 18-85 years of age
* Ruptured aneurysmal SAH confirmed by angiography and repaired by neurosurgical clipping or endovascular occlusion (coiling)
* Modified Glasgow Coma Scale (mGCS) score ≥ 10 and Hunt Hess 1-4 within 72 hours of presumed aneurysm rupture
* Enrollment and initiation of nVNS treatment must occur within 72 hours of presumed aneurysm rupture
* Provide a legally obtained informed consent form from the participant or the legally authorized representative (LAR); telephonic consent is acceptable
* Female participants of reproductive age must have a negative pregnancy test result (urine or blood)
Exclusion Criteria:
* Use of any concomitant electrostimulation device, including a pacemaker, defibrillator, or deep brain stimulator
* No plan to secure aneurysm, defined as aneurysm that has not been surgically or endovascularly treated
* Previous neck dissection or radiation
* History of carotid artery disease or carotid surgery/dissection
* History of secondary or tertiary heart blocks, ventricular tachycardia, or supraventricular tachycardia (SVT; including atrial fibrillation)
* Screws, metals, or devices in the neck
* Currently participating in an investigational drug or device clinical trial with potential to confound data collection
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.
