Study Details

Study Description

Brief Summary

The purpose of this study is to determine if additional interventions will assist with decreasing the risk and/or severity of thromboembolism (clotting complications) in patients who have experienced a major traumatic event.

Condition or Disease Intervention/Treatment Phase

Arms and Interventions

Arm Intervention/Treatment
Experimental: Thrombate infusion

Drug: Thrombate infusion
Bolus intravenous infusion of Thrombate will be given to achieve antithrombin (AT) activity levels at 150% after the 3rd dose of Enoxaparin. The dose will be based on patient weight.

Placebo Comparator: Placebo

Drug: Placebo
Normal Saline will be given as one time IV after the 3rd dose of Enoxaparin. The dose will be based on patient weight.

Outcome Measures

Primary Outcome Measures

  1. Number of participants with incidences of venous thromboembolism (VTE ) [14 days post hospital admission]

  2. Number of participants with incidence of antifactor Xa (anti-FXa) of ≥0.2 IU/mL [14 days post hospital admission]

Secondary Outcome Measures

  1. Time taken to achieve anti-FXa of ≥0.2 IU/mL [14 days post hospital admission]

  2. Number of enoxaparin dose escalations [from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]

  3. Number of incidences of participants with other thrombotic complications (arterial thrombosis, myocardial infarction, stroke) [from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]

  4. Number of incidences of participants with bleeding events (interoperative bleeding, abdominal bleeding) [from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]

  5. Number of hospital free days [from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]

  6. Number of Ventilator free days [from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]

  7. Number of ICU free days [from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]

  8. Level of Anti-FXa [from the time of hospital admission up to hospital day 7]

  9. Antithrombin (AT) activity level [from the time of hospital admission up to hospital day 7]

  10. Change in level of the endothelial marker syndecan-1 as assessed by a blood test [time of hospital admission, day1, day2, day 3, day 4, day 5, day6, day 7]

  11. Change in level of the endothelial marker thrombomodulin as assessed by a blood test [From the time of hospital admission to day 7]

  12. Change in level of Inflammatory marker Tumor necrosis factor alpha (TNFα) as assessed by a blood test [From time of hospital admission to day 7]

  13. Change in level of Inflammatory marker Interleukin-8 (IL-8) as assessed by a blood test [From time of hospital admission to day 7]

  14. Change in level of Inflammatory marker Interleukin-6(IL-6) as assessed by a blood test [time of hospital admission, day1, day2, day 3, day 4, day 5, day6, day 7]

  15. Change in level of Inflammatory marker Interleukin-1 beta (IL1b) as assessed by a blood test [From time of hospital admission to day 7]

  16. Change in level of Inflammatory marker Interleukin-1 alpha (IL1a) as assessed by a blood test [From time of hospital admission to day 7]

  17. Change in level of Inflammatory marker Interferon -gamma (INFg) as assessed by a blood test [From time of hospital admission to day 7]

  18. Number of participants with In-hospital mortality [from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]
