Trial summary

Neonatal hypoxic ischemic encephalopathy (HIE) is a serious neurological condition characterised by acute or subacute brain injury arising from perinatal hypoxia. HIE is thought to affect approximately 0.2% of live births, and is associated with a high risk of mortality or long-term neurological disability. Read more about this study

About this study

Official title: Magnetic Resonance Imaging (MRI) and Spectroscopy (MRS) Biomarkers of Neonatal Hypoxic Ischemic Encephalopathy

Neonatal hypoxic ischemic encephalopathy (HIE) is a serious neurological condition characterised by acute or subacute brain injury arising from perinatal hypoxia. HIE is thought to affect approximately 0.2% of live births, and is associated with a high risk of mortality or long-term neurological disability.

Accurate biomarkers for long-term neuro-developmental outcome following HIE are extremely important both for clinical management and the evaluation of therapeutic approaches. According to a recent meta-analysis, the ratio of the cerebral concentrations of lactate and N-acetyl aspartate (NAA), two neuro-metabolites detectable with magnetic resonance spectroscopy (MRS), currently represents the most accurate prognostic indicator of outcome following HIE. However, for various technical reasons standard MRS methods do not offer optimal sensitivity for detecting lactate, which may potentially be improved with a custom lactate editing MRS sequence. In addition, while perfusion has also been suggested as a potential biomarker for neuro-developmental outcome following HIE, due to a paucity of MR perfusion imaging studies in neonates, the prognostic accuracy of perfusion MR measures has not been evaluated in comparison with more established MR biomarkers. The aims of this study are:

  1. to evaluate the relative sensitivity of a custom lactate editing MRS pulse sequence (specialist software) relative to the standard point resolved (PRESS) MRS sequence for detecting lactate in neonates with suspected HIE.
  2. to evaluate the sensitivity and specificity of MR perfusion measures in comparison to MRS measures as predictors of neuro-developmental outcome at 2 years.

What is being measured

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

  1. sensitivity of lactate editing MR spectroscopy sequence (software) relative to that of the standard MR spectroscopy sequence.

    The primary end-point will be reached when lactate and perfusion data have been collected from 30 neonates. The efficacy of the custom-MRS lactate editing sequence will be assessed relative to that of the standard MRS sequence for the detection of lactate (by comparing the lactate concentration (in mM) measured from the lactate edited MR spectra to that measured from the standard MR spectra).

    Measured: 12 months

Secondary outcomes (1)
  1. prognostic accuracy (sensitivity and specificity) of MRI and MRS for predicting motor outcome at age 2

    The secondary end-point will be reached upon completion of a neurological development assessment at the age of 2 years. Patients will be classified as having a good or poor outcome based on their motor skills at age 2, and the prognostic accuracy (eg sensitivity and specificity for predicting neuromotor outcome) of the standard and new MRI and MRS sequences will be assessed.

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

An observational study of Hypoxic Ischemic Encephalopathy, run by University Children's Hospital, Zurich at 1 site in Switzerland.

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 1 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 25 Sep 2019. 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 Switzerland. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

sensitivity of lactate editing MR spectroscopy sequence (software) relative to that of the standard MR spectroscopy sequence. (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 25 Sep 2019.
