Summary

This trial is testing a device that stimulates a nerve in the neck, along with usual medical care, to help patients with mild-to-moderate brain injuries. The goal is to prevent serious complications like severe inflammation and breathing problems.

Who is the study for?
This trial is for hospitalized patients aged 18-80 with mild-to-moderate traumatic brain injury (TBI) not on mechanical ventilation. They must have a Glasgow Coma Scale score of at least 12 and a Lung Injury Prediction Score of at least 2, indicating potential respiratory issues. Exclusions include severe lung or heart conditions, pregnancy, burns over a large body area, participation in another trial, and certain critical health statuses.
What is being tested?
The study tests non-invasive vagus nerve stimulation (nVNS) using the gammaCore Sapphire S device plus standard care against standard care alone to prevent worsening of TBI-induced respiratory distress. The goal is to avoid progression towards severe inflammation and the need for invasive breathing support within the first month after injury.
What are the potential side effects?
While specific side effects are not listed here, nVNS devices can typically cause discomfort at the site of application, headache, dizziness or changes in blood pressure. Standard care side effects depend on treatments used but may include medication reactions or complications from hospital interventions.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Receiving Standard of CareExperimental Treatment1 Intervention
Patients will be managed according to the institutional best practices and SOC for TBI.
Group II: Receiving Non-invasive vagus neurostimulationExperimental Treatment2 Interventions
nVNS treatment will be applied three times daily. One treatment is defined as 2 consecutive stimulations: one, 2-minute stimulation on the side of the neck followed by a second, 2-minute stimulation on the same side of the neck. The treatment will be done 3 times per day (morning, mid-day and 1 hour before bed at night), every day, until patient is discharged from the hospital or requires mechanical ventilation. Patient will record the time they administered these treatments. If the patient is unable to do this, a research staff member who has been trained on the device can assist. Will also receive SOC for TBI.

Other Research
Non-invasive vagus nerve stimulation (nVNS) works by delivering electrical impulses to the vagus nerve, which can modulate neural activity and reduce inflammation. This is particularly important for TBI patients as it may help prevent the progression of systemic inflammatory response syndrome (SIRS) and other complications such as severe respiratory distress. By targeting the vagus nerve, nVNS can potentially stabilize autonomic functions and improve overall outcomes in TBI patients. Other common treatments for TBI include pharmacologic interventions to manage symptoms and prevent secondary injury, as well as physical and cognitive rehabilitation to support recovery.
Evaluation of current post-concussion protocols.
