Trial Outcomes & Findings for Traumatic Injury Clinical Trial Evaluating Tranexamic Acid in Children: A Pilot and Feasibility Study (NCT NCT02840097)

NCT ID: NCT02840097

Last Updated: 2021-09-05

Results Overview

Neurocognitive functioning and quality-of-life measures; range from 0 to 100 quality of life units with higher scores representing better outcomes. Measurements occur at 1 week, 1 month, 3 months, and 6 months to generate an area under the curve of quality of life units.

Measure
Tranexamic Acid Dose A
Subjects will receive a 15 mg/kg bolus of tranexamic acid over 10 minutes followed by a 2mg/kg/h over 8 hours. This represents 31mg/kg total dose of TXA. Tranexamic Acid: Active drug is provided to participants as described based on the TXA arm they are randomized to.
Tranexamic Acid Dose B
Subjects will receive a 30 mg/kg bolus of tranexamic acid over 10 minutes followed by a 4 mg/kg/h over 8 hours. This represents 62 mg/kg total dose of TXA. Tranexamic Acid: Active drug is provided to participants as described based on the TXA arm they are randomized to.
Placebo
Subjects in the placebo group will receive a bolus dose of normal saline over 10 minutes followed by a normal saline infusion over 8 hours. Placebo: Normal saline is provided to participants if randomized to this treatment arm.

Population: Brain Injury and Both groups

Intracranial hemorrhage progression on cranial computed tomography (CT) imaging; hemorrhage will be measured using the ABC/2 volume estimation and relative to the total brain volume (calculated by the XYZ/2 volume estimation); more intracranial hemorrhage progression represents a worse outcome. Change is calculated as the difference between the baseline and repeat cranial CT imaging. The repeat CT is conducted 24 hours (±6 hours) after the baseline CT.
