About this study

The purpose of this study is to improve the ability of the investigators to monitor brain health in newborn babies at risk of brain injuries. The researchers will be using an investigational system of devices to non-invasively (that, is, without penetrating the skin), measure the amount of oxygen going to and being used by the brain. They will be taking some bedside research measurements during the babies' stay at the hospital. With these measurements, the intention is to study the role of oxygen in brain injury and test the efficacy of the research device and its potential as a permanent bedside diagnostic device.

Read the detailed description

Neonatal encephalopathy (NE) due to hypoxia-ischemia is a major public health concern as it occurs in 6/1000 live term births and has devastating consequences. Many affected neonates suffer lifelong motor disabilities and epilepsy, but increasingly the high prevalence of cognitive and behavioral disabilities is becoming appreciated. In hypoxia-ischemia there is a decrease in blood and oxygen delivery, followed by reperfusion with transient energy recovery. What follows is a "window of opportunity" where excitotoxicity and associated increased cerebral metabolism eventually lead to secondary energy failure and irreversible cell death. In this window, therapeutic hypothermia (TH) is currently the only treatment available with proven efficacy. TH acts primarily by decreasing cerebral metabolism, thus preserving energy stores.

Although the current gold standard for brain injury detection is magnetic resonance imaging (MRI), MRI is impractical as a screening tool and cannot provide bedside monitoring to optimize individual responses to therapies. Commercially available continuous wave (CW) near infrared spectroscopy (NIRS) systems provide bedside measures of cerebral oxygen saturation (SO2) but SO2 alone cannot assess oxygen metabolism, as oxygen delivery is not taken into account. What is needed is a bedside tool that can monitor cerebral metabolism to detect elevations in metabolism that suggest evolving hypoxic-ischemic injury, and decreases in metabolism that suggest response to therapy. Cerebral oxygen consumption (CMRO2) is a direct measure of cerebral metabolism and therefore the investigators propose to measure an index of CMRO2 at the bedside using the innovative combination of Frequency Domain Near-Infrared Spectroscopy (FDNIRS) and Diffuse Correlation Spectroscopy (DCS). The initial studies from the investigators show that CMRO2 is elevated in neonates with MRI evidence of perinatal brain injury, and confirm that neonates on TH have significantly lower CMRO2 than normal controls. Following these exciting results, they now propose a feasibility study to determine if FDNIRS-DCS can screen for involvement, assess response to treatment, and predict outcomes in one of the largest neonatal populations requiring early screening and immediate intervention: neonatal encephalopathy. To assess early outcomes, the research team proposes an innovative combination of advanced neurobehavioral testing, regional FDNIRS-DCS measures and quantitative MRI analysis using MRIs obtained without sedation. If the hypotheses prove true, it will help in determining if bedside indices of CMRO2 provided by FDNIRS-DCS can optimize TH for individual neonates, thereby improving neurodevelopmental outcomes. Success at this stage will also allow exploration of the potential for FDNIRS-DCS to determine the additional benefits of emerging new treatments for NE and to screen for other treatable neonatal disorders.

What is being measured

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

  1. Compare metrics such as hemoglobin oxygen saturation and cerebral metabolic rate of oxygen consumption as obtained from novel NIRS technology in neonates at risk for brain injury to normal controls.

    The infants undergoing treatment with therapeutic hypothermia (TH) and those who are identified with neonatal brain injury but are not candidates for TH will be compared. Both groups will also be compared to normal controls.

    Measured: early inpatient phase (0-2 months of age)

Secondary outcomes (2)
  1. Perform NIRS, MRI and Neurodevelopmental testing (using Bayley Scales for Infant Development) between 2-12 months.

    Explore correlations between all NIRS and MRI measures, and neurodevelopmental outcome at 2-12 months.

    Measured: up to 12 months of age

  2. Perform Neurodevelopmental testing at 16-24 months using Bayley Scales for Infant Development.

    Explore correlations between all NIRS and MRI measures, and neurodevelopmental outcomes.

    Measured: up to 24 months of age

Questions about this trial

What is this clinical trial studying?

An observational study of Hypoxic Ischemic Brain Injury and Neonatal Encephalopathy, run by Boston Children's Hospital at 3 sites 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 7 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: looking for participants now, as of the sponsor's last update on 10 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Rutvi Vyas, MS (857-218-5445, rutvi.vyas@childrens.harvard.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Compare metrics such as hemoglobin oxygen saturation and cerebral metabolic rate of oxygen consumption as obtained from novel NIRS technology in neonates at risk for brain injury to normal controls. (time frame: early inpatient phase (0-2 months of age)). 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 10 Dec 2025.
