Study summary

Head injuries are a major public health issue, with an estimated annual incidence in Europe of 262 per 100,000 population. Light head injury (SCI), defined by a Glasgow score between 13 and 15, constitutes the majority (71% to 98%) of head injury cases. Despite a generally good prognosis, patients with TCL have a low but real risk of brain damage, whose prevalence is estimated at 5%. Cerebral computed tomography (CT) because of its high sensitivity for the detection of posttraumatic intracranial lesions (LIC), is currently considered the gold standard for the diagnosis of these lesions in patients considered at risk after clinical evaluation. The number of cTCTs performed is high with no lesion in more than 90% of cases. The S100B protein, a marker of brain tissue damage, is reported to reliably exclude the presence of brain lesions in adults as well as antiaggregants. These numerous studies show that its serum assay in combination with the clinical decision algorithms allows, thanks to a sensitivity close to 100% for brain lesions, to reduce the number of CTMc currently prescribed by approximately 30%, and therefore to decrease unnecessary exposure to radiation. Although there is no study on the subject, a gain on the duration of care in emergencies can be expected as well as a reduction on the cost of care by a dosage price three times less higher than the TDMc. Expert opinion for the use of this assay in the management of moderate-risk TCL at threshold ≤ 0.10 μg / L in 3h post-TC to ensure sensitivity of 100%, was published in 2014 in the Annales Françaises de Médecine d'Urgence.

The use of anticoagulants has continued to increase in recent years. In 2013, it is estimated that 3.12 million patients received at least one anticoagulant in France. Currently, the international and French recommendations indicate the achievement of cTCT in anticoagulated TCL because it is an independent risk factor for cerebral injury and is therefore considered to be a high risk TCL. LIC. The hypothesis of this study is that the S100B protein assay could also exclude the presence of brain lesion after TCL under anticoagulation in adults

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Mar 2018; primary completion for Mar 2020, 24 months later.

Of 43 non-industry observational studies under Craniocerebral Trauma, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 49. This study's planned 24 months is below that.

Counting every sponsor, half of 43 studies reached it within 32 months; a quarter within 15 and three quarters within 49.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 17, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
