About this study

Official title: Serial Multiomics Profiling Using Serum and Cerebrospinal Fluid Samples Following Out-of-hospital Cardiac Arrest: a Prospective Observational Study

The goal of this observational study is to identify further pathophysiologic mechanism of secondary brain injury following cardiac arrest by using serial multiomics profiling of serum and cerebrospinal fluid (CSF) samples. The main question it aims to answer is:

  1. The main question it aims to answer is: What are the dynamic molecular changes in serum and CSF that reflect the pathophysiological mechanisms of secondary brain injury after cardiac arrest? B. What are the differences in serum and CSF multiomic signatures between varying severities of cardiac arrest, and how are these differences associated with the underlying pathophysiological mechanisms of secondary brain injury?

Serum and CSF samples that have already been prospectively collected from participants and stored in the BioBank will be used for this analysis.

What is being measured

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

  1. Neurological outcome

    Neurological outcome is evaluated using the Cerebral Performance Category (CPC) scale. The CPC score ranges from 1 to 5, where 1 indicates good cerebral performance (normal/mild disability), 2 indicates moderate cerebral disability, 3 indicates severe cerebral disability, 4 indicates coma or vegetative state, and 5 indicates brain death. Higher scores represent a worse neurological outcome.

    Measured: after 6 months from return of spontaneous circulation

Secondary outcomes (1)
  1. Illness severity score of cardiac arrest (rCAST)

    llness severity is assessed using the revised Post-Cardiac Arrest Syndrome for Therapeutic hypothermia (rCAST) score, which incorporates initial rhythm, blood pH, lactate levels, motor response, and arrest duration. The total score ranges from 0 to 15, with higher scores indicating greater illness severity and worse prognosis. Based on the total score, patients are categorized into three severity risk groups: low severity (0-5 points), moderate severity (6-8 points), and high severity (9-15 points), where the high-severity group reflects the worst clinical prognosis and highest risk of poor outcome.

    Measured: immediately after return of spontaneous circulation

Questions about this trial

What is this clinical trial studying?

An observational study of Cardiac Arrest (CA) and Hypoxic-Ischemic Brain Injury, run by Chungnam National University Hospital at 1 site in South Korea.

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 4 inclusion and 3 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: under way, not looking for participants, as of the sponsor's last update on 10 Sep 2026. 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 South Korea. 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?

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?

Neurological outcome (time frame: after 6 months from return of spontaneous circulation). 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 NCT07090577, which also lists 3 linked publications.

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 Sep 2026; AzTrials last refreshed its copy on 7 Nov 2026.
