About this study
Official title: Clinical Utility of Serum Biomarkers for the Management of Neonatal Hypoxic Ischemic Encephalopathy (HIE) Control Levels
Hypoxic-ischemic encephalopathy (HIE) is a serious birth complication due to systemic asphyxia which occurs in about 20 of 1,000 full-term infants and nearly 60% of premature newborns. Between 10-60% of babies who exhibit HIE die during the newborn period and up to 25% of the HIE survivors have permanent neurodevelopmental handicaps in the form of cerebral palsy, mental retardation, learning disabilities, or epilepsy. HIE also has a significant financial impact on the health care system. In the state of Florida, the total cost for initial hospitalization is $161,000 per HIE patient admitted, but those costs don't take into account the life-long costs.
Current monitoring and evaluation of HIE, outcome prediction, and efficacy of hypothermia treatment rely on a combination of a neurological exam, ultrasound, magnetic resonance imaging (MRI) and electroencephalography (EEG). However, these methods do a poor job in identifying non-responders to hypothermia. MRI requires transport of the neonate with a requisite 40-45 min scan, which is not appropriate for unstable neonates. Moreover, the amplitude integrated EEG (aEEG), a common bedside monitoring technique currently used in these patients to assess candidates and predict outcomes prior to hypothermia, can be adversely affected by hypothermia itself and the patient may not appear to improve until re-warming. Consequently, the development of a simple, inexpensive, non-invasive, rapid biochemical test is essential to identify candidates for therapeutic hypothermia, to distinguish responders from non-responders and to assess outcome. This research is the first step needed to treat neonates with HIE employing a personalized medical approach using serum proteins GFAP and UCH-L1 as biomarkers and by monitoring neonates responses to therapeutic hypothermia. These biomarkers will aid in the direct care by providing a rapid test to predict outcomes and select candidates who are likely to benefit from therapeutic hypothermia and gauge a response to the neuroprotective intervention.
Read the detailed description
Control Neonates will be easily obtained from a single center, Shands UF. The control samples will be derived from two groups: (1) "Healthy Controls" will be healthy neonates with Apgar scores ≥ 7 at 1 minute and ≥ 8 at 5 minutes and no other medical problems associated with neurologic injury such as hyperbilirubinemia or hypoglycemia. This group will establish a negative control and will have 500-800µL of blood collected at the time of standard blood metabolic screens (at 24 and 48 hours of life). (2) "Clinical Controls" will be healthy neonates evaluated for jaundice, with multiple blood samples drawn between birth and 48 hours of life to monitor serum bilirubin concentrations. They will have an additional 0.8-1 mL of blood drawn at the time of any clinical sample (venous or heel stick) is performed. In addition, neonates will be excluded if they show signs of sepsis or hypoglycemia (< 40). The neonates' bilirubin will be plotted using the American Academy of Pediatrics risk-based stratification method, the Bhutani monogram (which is a based on the serum bilirubin concentration and the hours of life). Clinical control neonates must have low-risk or low-intermediate bilirubin concentrations, with virtually no risk of brain injury.

What participants receive

blood sampleProcedure or surgery
Blood will be collected to test for concentrations of UCH-L1 and GFAP.
| Study group | Role | What they receive |
|---|---|---|
| Healthy Control | The healthy control group will have 500-800uL (less than 1 mL) of blood collected. This sample will be obtained at the same time that the neonate is already having a standard blood screenings drawn at 24 and 48 hours of life. Receives: Procedure: blood sample | |
| Clinical Control | The clinical control group will be healthy neonates that are being evaluated for jaundice, with multiple blood samples drawn between birth and 48 hours of life to monitor serum bilirubin. With these already scheduled lab draws, we will draw an additional 0.8-1 mL of blood. Receives: Procedure: blood sample |
What is being measured
The primary outcome is the main question the study is designed to answer.
Levels of UCH-L1 in blood
Determining if UCH-L1 concentrations measured in neonates with HIE are significantly elevated as compared to controls. Evaluate serum biomarker concentrations from a cohort of neonatal HIE patients who are candidates for hypothermia. These samples will be compared to samples collected from the two cohorts of neonatal "control" subjects.
Measured: 72 hours
Secondary outcomes (1)
Levels of GFAP in blood
Determining if GFAP concentrations measured in neonates with HIE are significantly elevated as compared to controls. Evaluate serum biomarker concentrations from a cohort of neonatal HIE patients who are candidates for hypothermia. These samples will be compared to samples collected from the two cohorts of neonatal "control" subjects.
Measured: 72 hours

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?
Levels of UCH-L1 in blood (time frame: 72 hours). It is what the study was designed to measure, not a finding.

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 21 Jun 2018.
