About this study
Official title: Prospective, Interventional Study Evaluating the Feasibility and Safety of the Esophageal Cooling Device in 15 Patients Suffering From Traumatic Brain Injury and Treated With Targeted Temperature Management
The aim of this prospective, interventional study is to assess the feasibility and safety of the Esophageal Cooling Device in patients from suffering from traumatic brain injury who the treating physician is treating with targeted temperature management. Comparison of outcomes will be made to historical controls. The primary outcome is the feasibility of inducing, maintaining, and rewarming patients from targeted temperature management using the Esophageal Cooling Device (cooling rate, rewarming rate, and the percent of time within goal temperature during the goal-temperature maintenance period). Evaluation of adverse events (including cardiac arrhythmias, severe bradycardia, myocardial infarction/re-infarction, dysphagia, odynophagia, aspiration pneumonia, non-aspiration pneumonia, reflux, esophageal injury, and esophagitis) will be closely monitored during the whole period of targeted temperature management (secondary endpoint).
Read the detailed description
Controlling patient's body temperature, and in particular, reducing body temperature in a treatment referred to as targeted temperature management, has been shown to improve outcomes for many conditions, including neonatal hypoxic ischemic encephalopathy, cardiac arrest, and traumatic brain injury. However, available modalities for inducing targeted temperature management have a number of technical, logistical, and financial barriers. The Esophageal Cooling Device is a multi-chambered silicone tube placed in the esophagus that provides a highly efficient heat transfer to or from a patient.
Traumatic brain injury (TBI) is a major cause of death and severe disability throughout the world. Current methods of traumatic brain injury treatment include reduction of brain swelling and edema, both by surgical means, as well as by reduction of temperature and avoidance of fever. Methods used to reduce temperature and control fever include surface devices, such as ice packs and water circulating blankets, and intravascular catheters, which are placed into a blood vessel.
The esophagus is in close proximity to blood flow from the heart and great vessels, and the Esophageal Cooling Device (ECD) is designed to take advantage of this heat exchange environment. The ECD's ability to decompress the stomach and avoid distention of the esophagus away from the device ensures good contact with the esophageal mucosa, and thus maximizes heat transfer from the patient. The ECD replaces the standard gastric tube which is placed in the target patient population as a routine standard of care, is made of standard medical-grade silicone, and is generally similar in size and shape to the gastric tubes currently used. Initial mathematical, animal, and human data have shown strong support for the efficacy and safety of the ECD.
The aim of this prospective, interventional study is to assess the feasibility and safety of the Esophageal Cooling Device in patients from suffering from traumatic brain injury who the treating physician is treating with targeted temperature management. Comparison of outcomes will be made to historical controls. The primary outcome is the feasibility of inducing, maintaining, and rewarming patients from targeted temperature management using the Esophageal Cooling Device (cooling rate, rewarming rate, and the percent of time within goal temperature during the goal-temperature maintenance period). Evaluation of adverse events (including cardiac arrhythmias, severe bradycardia, myocardial infarction/re-infarction, dysphagia, odynophagia, aspiration pneumonia, non-aspiration pneumonia, reflux, esophageal injury, and esophagitis) will be closely monitored during the whole period of targeted temperature management (secondary endpoint).

What is being measured
The primary outcome is the main question the study is designed to answer.
Time to Initiation of Temperature Management
Time to initiation of targeted temperature management, as measured from the time a decision is made to begin targeted temperature management, to the time the esophageal cooling device is in place.
Measured: 30 days
Secondary outcomes (2)
Composite of Performance Outcomes
Secondary performance outcomes include the feasibility of inducing, maintaining, and rewarming patients from targeted temperature management using the Esophageal Cooling Device. Specifically, cooling rate, rewarming rate, and the percent of time during the goal- temperature maintenance period within 1°C of goal temperature (typically 33°C, but with some centers using anywhere from 32°C to 36°C) will be measured.
Measured: 36 hours
Composite of Safety Outcomes
Secondary safety outcomes include evaluation of adverse events including the following: cardiac arrhythmias, severe bradycardia, myocardial infarction/re-infarction, dysphagia, odynophagia, aspiration pneumonia, non-aspiration pneumonia, reflux, esophageal injury, and esophagitis.
Measured: Assessed over 36 hours of treatment and up to 30 days of follow-up.

Questions about this trial
What is this clinical trial studying?
A study testing Esophageal Cooling Device (ECD), manufactured by Advanced Cooling Therapy, Inc. in people with Traumatic Brain Injury, run by Advanced Cooling Therapy, Inc., d/b/a Attune Medical at 1 site in Ukraine.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Ukraine. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 2 Sep 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Time to Initiation of Temperature Management (time frame: 30 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02420639, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2021.
