Outcome

Type Measure Description Time frame Safety issue
Primary Safety The primary endpoint for this study is safety. The following safety endpoints will be assessed:
Type, incidence, severity, timing, seriousness, and relatedness of adverse events.
Lower extremity deep vein ultrasound will be performed to identify and localize deep or superficial venous thrombosis.
Vital signs
Laboratory assessments. Particular attention will be paid to serial hemoglobin and hematocrit measurements.
DVT, PE, thromboembolism, MI and stroke.
6 months Yes
Secondary Efficacy The following secondary endpoints will also be assessed in order to measure various aspects of neurological status:
GOSE at hospital discharge, 3, and 6 months post-TBI
Neurobehavioral Rating Score at hospital discharge, 3, and 6 months post TBI
Disability Rating Score at hospital discharge, 3, and 6 months post TBI
6 months No
