Trial summary

Hundreds of babies in the world are being treated with brain cooling to prevent brain injury after they lose oxygen at birth. This study will use the newly developed information from the magnet resonance image to determine the actual temperature of the brain. Read more about this study

About this study

Official title: MRI Thermal Imaging of Infants Undergoing Cooling for HIE

Hundreds of babies in the world are being treated with brain cooling to prevent brain injury after they lose oxygen at birth. This study will use the newly developed information from the magnet resonance image to determine the actual temperature of the brain. This will enable us to determine if the brain is being uniformly cooled and if techniques that provide cooling need to be changed to improve the injury prevention from cooling.

Read the detailed description

We propose to develop a non-invasive measurement of brain tissue temperature and to apply this measurement of infants under-going cooling for HIE

  1. We propose to do this by refining the use of the MRI evaluation of the NAA-H20 frequency shift. This molecular relationship is quite accurate (based on preliminary studies of an NAA-H20 phantom subject to controlled temperature variations) for measuring relative temperature changes.
  2. The next step will be to perform further phantom imaging with continuous temperature measurements and to expand the phantom model. This work needs funding support to be completed.
  3. At the same time we will be applying the MRI thermal imaging protocol to infants whom have experienced HIE and who are being treated with hypothermia to ameliorate the HIE. We have IRB approval to approach families and to obtain the required data during clinically indicated MRI scans, this data accumulation will add an additional 3-5 minutes to the MRI. We will then perform a second MRI after the infant is rewarmed. We will compare the pairs of readings at two different core temperatures from at least five regions of the brain.
  4. We will evaluate results of regional temperature measurements to determine if cooling of the human infant brain is uniform.
  5. We will compare the two modalities of cooling to determine if selective head cooling and total body cooling provide similar distribution of cooling.
  6. The final goal will be to compare MRI identified injury patterns to the temperature distribution in order to determine if distribution of cooling is related to outcome.

What is being measured

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

  1. Brain temperature

    MRI data will be used to estimate regional brain temperature

    Measured: Day three of cooling

Secondary outcomes (1)
  1. Brain temperature upon rewarming

    Estimate of brain temperature when rewarmed

    Measured: 2 hours after initial MRI

Questions about this trial

What is this clinical trial studying?

An observational study of Hypoxic Ischemic Encephalopathy, run by Vanderbilt University at 1 site in United States.

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 2 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: withdrawn, as of the sponsor's last update on 3 Jun 2015. 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 States. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Brain temperature (time frame: Day three of cooling). 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 NCT01128673, which also lists 1 linked publication.

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 3 Jun 2015.
