Trial summary

Cooling the whole body to 32-34 degrees Centigrade from the normal of around 37 degrees Centigrade for 24 hours has been shown to be an effective way of reducing damage to brain function after return of spontaneous circulation when someone has been resuscitated from cardiac arrest.

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 35 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Human volunteers aged over 18. The upper age limit, as is standard for risk mitigation in such studies, is 35. The volunteer must have capacity to understand the trial and give informed consent to participate. If the volunteer's first language is not English we will make use of Sussex Interpreting Services, a professional interpreting service.

Who cannot join

  • Pregnancy. Any disclosed medical condition. Any medical condition detected on examination. Core temperature outside stated parameters.
  • We will ask the volunteer to confirm that they are otherwise healthy, taking no regular medication (except the oral contraceptive pill), are not using recreational drugs and have no significant past medical history, in particular cardiovascular disease of any sort, thyroid disease, diabetes mellitus or other metabolic disease.

About this study

Cooling the whole body to 32-34 degrees Centigrade from the normal of around 37 degrees Centigrade for 24 hours has been shown to be an effective way of reducing damage to brain function after return of spontaneous circulation when someone has been resuscitated from cardiac arrest. Cardiac arrest is a form of heart attack where the heart stops pumping.

The device is a prototype cooling vest. The investigators anticipate that this will be useful in ambulances, helicopters and emergency departments where there is a need for a portable, safe, easy-to-use, inexpensive, external, effective, readily-controlled and single-patient use device able to reduce body temperature by at least 1 degree Centigrade an hour to initiate cooling. What the investigators are doing in these trials is to demonstrate that the investigators can cool people and to get the best design possible for patient use. That means some of the initial prototypes will not resemble what we expect the eventual device to look like. The investigators will be undertaking the initial trials on 30 normal volunteers.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Reduction in core body temperature by 1 degree Centigrade.

    The cooling properties of the vest are under investigation, and this reduction is the primary outcome measure.

    Measured: 1 hour.

Secondary outcomes (4)
  1. Skin condition.

    As the cooling is performed by a cold vest applied directly to the skin we need to ensure that no skin damage is caused.

    Measured: 3 days.

  2. ECG abnormalities.

    ECG abnormalities: ECG abnormalities are common after cardiac arrest, and have been noted in cooled patients after cardiac arrest. We will monitor the ECG for any abnormalities. The following will be noted but will not terminate the study:

    Bradycardia of less than 15 beats per minute below baseline. Unifocal ventricular ectopics. Unifocal atrial ectopics. Any other cardiac abnormality will cause immediate termination of the study and intervention to treat as necessary. A defibrillator will be available in the study room.

    Measured: 3 hours.

  3. Sepsis.

    Sepsis: Increased rates of sepsis have been seen in intensive care units in patients who have received therapeutic hypothermia. We will enquire about sepsis symptoms in our follow-up contact.

    Measured: 3 days.

  4. Skin condition.

    Our aim is not to cause any skin damage to patients or volunteers. We will therefore inspect the skin after removing the vest or at any time before that if the volunteer expresses concern. We expect pallor of the skin during cooling and reddening during rewarming with some numbness and some discomfort, both during cooling and rewarming. We will regard any evidence of frostbite as a serious untoward injury (SUI) and this will result in suspension of the study and an investigation into the specific vest used and the general vest design and formulation. We regard this as a serious risk but highly unlikely in practice.

    Measured: 3 days.

Questions about this trial

What is this clinical trial studying?

A study testing Cooling in people with Hypothermia., run by Bodychillz Ltd at 1 site in United Kingdom.

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 2 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: status not confirmed, as of the sponsor's last update on 4 Mar 2014. 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 United Kingdom. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Rowland L Cottingham, FRCS FCEM (+44 1273 696955, rowley.cottingham@bodychillz.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Reduction in core body temperature by 1 degree Centigrade. (time frame: 1 hour.). 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 NCT02030236, which also lists 2 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 4 Mar 2014.
