About this study

Official title: Prognostic Potential of Prehospital S100B, Glial Fibrillary Acidic Protein (GFAP) and Neuron Specific Annuals (NSE) Levels in Patients Suffering Severe Traumatic Brain Injury (TBI)

The PreTBI III study aims to investigate the prognostic potential of prehospital and repeated in-hospital S100B, NSE and GFAP measurements as predictors of neurological outcome in patients suffering severe TBI. Knowledge on prehospital S100B, GFAP and NSE levels as predictors of neurological outcome and mortality may underline the potential of a point-of-care analysis. Possibly, the early biomarker levels may contributed to accurate monitoring of biomarker dynamics and hereby support neurosurgeons and anaesthetists in the clinical decision-making regarding treatment and level of care offered to the patient.

Hypotheses:

  1. Prehospital S100B level is a significant predictor of unfavourable neurological outcome (dichotomized disability rating scale (DRS) and glasgow outcome scale extended (GOS-E) measures) in severe TBI patients.
  2. Prehospital GFAP level is a significant predictor of unfavourable neurological outcome (dichotomized DRS and GOSE measures) in severe TBI patients.
  3. Prehospital NSE level is a significant predictor of unfavourable neurological outcome (dichotomized DRS and GOSE measures) in severe TBI patients.
  4. combined panel of prehospital S100B, GFAP and NSE levels is a significant predictor of unfavourable neurological outcome (dichotomized DRS and GOSE measures) in severe TBI patients.
  5. Unfavourable neurological outcome (dichotomized DRS and GOSE measures) in severe TBI patients can be predicted by dynamics in repeated measurements of S100B, GFAP and NSE.

What is being measured

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

  1. Sensitivity of se-S100B in relation to a binary outcome measured by by a yes/no question of "favorable neurological outcome" pick favorable/unfavorable

    Neurological outcome will be evaluated by a dichotomized glasgow outcome score extended (GOSE) as "Favorable (GOSE 5-8)/Unfavorable (GOSE 1-4)

    Measured: in relation to event within 1 year

  3. Positive predictive value of se-S100B in relation to a binary outcome measured by by a yes/no question of "favorable neurological outcome" pick favorable/unfavorable

    Measured: in relation to event within 1 year

  4. Negative predictive value of se-S100B in relation to a binary outcome measured by by a yes/no question of "favorable neurological outcome" pick favorable/unfavorable

Questions about this trial

What is this clinical trial studying?

An observational study of Traumatic Brain INjury, run by University of Aarhus at 1 site in Denmark.

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 24 Apr 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 Denmark. 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 se-S100B in relation to a binary outcome measured by by a yes/no question of "favorable neurological outcome" pick favorable/unfavorable (time frame: in relation to event within 1 year). The study lists 4 primary outcomes in all. 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 24 Apr 2019.
