  • Parent(s) who are English or Spanish literate (with assistance of interpreter)
  • Neonates that are born > 37 weeks and <44 weeks postmenstrual age at enrollment
  • Consultation by the pediatric neurology inpatient service due neonatal paroxysmal events, with normal neurologic examination and ultimate diagnosis of non-epileptic spells on continuous video-EEG (ordered for clinical purposes, not for research) OR consultation for hypoxic ischemic encephalopathy in neonates undergoing therapeutic hypothermia, with early exit from therapy owing to normal neurologic examination, normal continuous video-EEG and uncertain diagnosis of encephalopathy.

About this study

Official title: Neonatal Seizure Registry: The Role of Inflammation After Neonatal Seizures and Later Development of Epilepsy

The purpose of this study evaluate the relationship between inflammation and epilepsy in neonates with seizures after birth.

Read the detailed description

Seizures are a common symptom of neurologic dysfunction in the neonatal period, affecting more than 16,000 newborns in the United States per year. Over 25% of neonates with acute symptomatic seizures develop post- neonatal epilepsy (PNE), which is often resistant to medical therapies. There is a critical need to identify those patients most at risk for PNE and understand the mechanisms by which early seizures increase the propensity for recurrent seizures, in hopes of identifying novel therapeutic targets in this population. There is increasing evidence for the role of neuro-inflammation in the development of epilepsy. Levels of cytokines and micro-RNA (miRNA) may serve as markers of disease severity and have been implicated in epileptogenesis in animal models. The purpose of this study is to evaluate plasma cytokine and miRNA levels after neonatal-onset acute symptomatic seizures and determine their association with acute seizure severity and PNE.

Study groups in NCT04259125
Study groupRoleWhat they receive
Acute symptomatic seizuresThis is a cohort of 72 participants who will be enrolled into this study from the neonatal intensive care unit (NICU) after being diagnosed with seizures. They will be asked to contribute a blood specimen obtained ideally 48-96 hours (though blood collection allowed 24-120 hours) after seizures are diagnosed, to participate in an optional blood draw at 2-4 months of age, and to complete surveys at 12 \& 24 months of age.
Receives: Diagnostic Test: Blood draw; Other: Survey
ControlThis is a cohort of 15 participants who will be enrolled into this study from the neonatal intensive care unit (NICU) after having an EEG for possible seizures, but found to have a normal EEG. They will be asked to contribute a blood specimen obtained ideally 48-96 hours (though blood collection allowed 24-120 hours) after birth.
Receives: Diagnostic Test: Blood draw

What is being measured

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

  1. Seizure burden

    Investigators will evaluate the seizure burden from the initial diagnostic electroencephalogram (EEG) after birth by determining the average number of seizures per hour.

    Measured: At study entry

  2. Percentage of participants diagnosed with epilepsy

    The investigators will determine the proportion of participants who develop clinical and or electrographic seizures.

    Measured: 24 months of age

Secondary outcomes (5)
  1. Percentage of participants diagnosed with epilepsy

    The investigators will determine the proportion of participants who develop clinical and or electrographic seizures.

    Measured: 12 months of age

  2. Epilepsy Severity

    The investigators will administer an investigator-developed questionnaire designed to define the frequency of seizures (monthly, weekly, daily, or greater than daily).

    Measured: 12 months of age

  3. Epilepsy Severity

    The investigators will administer an investigator-developed questionnaire designed to define the frequency of seizures (monthly, weekly, daily, or greater than daily).

    Measured: 24 months of age

  4. Warner Initial Developmental Evaluation of Adaptive and Functional Skills (WIDEA-FS)

    The Warner Initial Developmental Evaluation of Adaptive and Functional Skills (WIDEA-FS) will be assessed at 12 months of age. The score ranges from 50 to 200 with higher scores associated with normal development.

    Measured: Assessment takes up to 15 minutes and will be conducted at 12 months of age

  5. Warner Initial Developmental Evaluation of Adaptive and Functional Skills (WIDEA-FS)

    The Warner Initial Developmental Evaluation of Adaptive and Functional Skills (WIDEA-FS) will be assessed at 24 months of age. The score ranges from 50 to 200 with higher scores associated with normal development.

    Measured: Assessment takes up to 15 minutes and will be conducted at 24 months of age

Questions about this trial

What is this clinical trial studying?

An observational study of Neonatal Seizure and Epilepsy, run by University of California, San Francisco at 4 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 6 inclusion and 6 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 26 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 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?

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?

Seizure burden (time frame: At study entry). The study lists 2 primary outcomes in all. 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 NCT04259125, 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 26 Jan 2026.
