Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of the clinical trial is to evaluate the effect of time on levels of Ubiquitin C-terminal Hydrolase-L1 (UCH-L1) and Glial Fibrillary Acidic Protein (GFAP) biomarker levels in a population of head injured subjects over the age of 18 presenting acutely with a Glasgow Coma Scale score 13-15 as well as in a group of uninjured control subjects.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cohort A

CT negative for acute intracranial lesion with initial blood draw within 4 hours of head injury

Blood draw

Intervention Type OTHER

Initial draw followed by additional blood draws every 4 hours thereafter, up to 24 hours from the initial blood draw (not to exceed 7 blood draws). Follow up blood draw at Day 7. Control group only undergoes 2 blood draws 4 hours apart on Day 1.

Cohort B

CT negative for acute intracranial lesion with initial blood draw within 4-6 hours of head injury

Blood draw

Intervention Type OTHER

Initial draw followed by additional blood draws every 4 hours thereafter, up to 24 hours from the initial blood draw (not to exceed 7 blood draws). Follow up blood draw at Day 7. Control group only undergoes 2 blood draws 4 hours apart on Day 1.

Cohort C

CT positive for acute intracranial lesion with initial blood draw within 4 hours of head injury

Blood draw

Intervention Type OTHER

Initial draw followed by additional blood draws every 4 hours thereafter, up to 24 hours from the initial blood draw (not to exceed 7 blood draws). Follow up blood draw at Day 7. Control group only undergoes 2 blood draws 4 hours apart on Day 1.

Cohort D

CT positive for acute intracranial lesion with initial blood draw within 4-6 hours of head injury

Blood draw

Intervention Type OTHER

Initial draw followed by additional blood draws every 4 hours thereafter, up to 24 hours from the initial blood draw (not to exceed 7 blood draws). Follow up blood draw at Day 7. Control group only undergoes 2 blood draws 4 hours apart on Day 1.

Cohort E

Uninjured control group

Blood draw

Intervention Type OTHER

Initial draw followed by additional blood draws every 4 hours thereafter, up to 24 hours from the initial blood draw (not to exceed 7 blood draws). Follow up blood draw at Day 7. Control group only undergoes 2 blood draws 4 hours apart on Day 1.

* Able to participate for up to 5 hours following the first study blood draw.
* Willing to undergo the Informed Consent process prior to enrollment into this study.
* Subject is able to be enrolled into a control cohort that has not yet been closed to enrollment

Exclusion Criteria

* Participating in an interventional, therapeutic clinical study that may affect the results of this study (an observational study would be acceptable).
* Time of injury cannot be determined.
