Clinical Trial Summary

This study will evaluate if traumatic intracranial hemorrhage can be safely ruled out by using a microwave scanner (MD100) in conjunction with a combination of different brain biomarkers analyzed in serum.


Description:

This is a prospective, open, multicentre trial that will enrol patients presenting to the Emergency Department (ED) because of isolated head trauma or head trauma as part of a multi trauma. Microwave scanning characteristics and biomarkers in patients with traumatic intracranial haemorrhage (TICH) (Group A) will be compared to patients with head trauma that do not have TICH (Group B). All adult patients with trauma to the head will be eligible for inclusion if a medical professional has evaluated the risk of spine injury. After additional physical examination, control of inclusion- and exclusion criteria and after informed consent has been acquired, the microwave measurement and blood sampling will be performed. Before enrolment in the study, and in the acute phase, one of the investigators or a member of the investigator staff must explain verbally the implications of study participation to the patient, and the patient is asked to give a verbal consent. As soon as is practically possible after the acute phase of the disease, the patient will sign and personally date the informed consent form. In cases where the patient is not capable to read and/or sign the informed consent, due to disability, an independent witness shall be present throughout the process of reading the written informed consent and any other information aloud and explained to the prospective patient. As an independent witness, healthcare professionals who are not responsible or in any way involved in the patient's care or treatment are accepted. The independent witness can sign on the behalf of the patient in the presence of the patient and the Investigator. More details of the informed consent procedure are described in this Clinical Investigation Plan, section 6.3. The microwave measurement will take less than five minutes (the duration of the actual measurement is about 1,5 min and will not interfere with the patient's standard of care). The Research Nurse or the Investigator documents all patient clinical trial information in the eCRF. Safety and usability will be evaluated throughout the trial, and a safety follow-up will be performed by the Research Nurse or Investigator approximately 24 hours after the measurement procedure. During the data processing phase of study, the result of the microwave measurement will be compared to the result of the biomarkers, CT examination and the patient's final diagnosis. As a control group, approximately 50 demographically matched healthy volunteers (Group C) will be asked to participate in the trial. The trial will provide knowledge of the predictive value of microwave measurement and biomarkers for the diagnosis of intracranial haemorrhages in the acute TBI phase.
