Official title

Antithrombin to Improve Thromboprophylaxis and Reduce the Incidence of Trauma-Related Venous Thromboembolism (TRAIT)

Overview

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.

Interventions

  • Drug Thrombate infusion
    Bolus intravenous infusion of Thrombate will be given to achieve antithrombin (AT) activity levels at 150% before the 3rd dose of Enoxaparin. The dose will be based on patient weight.
  • Drug Placebo
    Normal Saline will be given as one time IV before the 3rd dose of Enoxaparin. The dose will be based on patient weight.

Primary outcome measures

  • Number of participants with incidences of venous thromboembolism (VTE ) [Time frame: 14 days post hospital admission]
  • Number of participants with incidence of antifactor Xa (anti-FXa) of ≥0.2 IU/mL [Time frame: 14 days post hospital admission]
Secondary outcome measures (12)
  • Time taken to achieve anti-FXa of ≥0.2 IU/mL [Time frame: 14 days post hospital admission]
  • Number of enoxaparin dose escalations [Time frame: from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]
  • Number of incidences of participants with other thrombotic complications (arterial thrombosis, myocardial infarction, stroke) [Time frame: from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]
  • Number of incidences of participants with bleeding events (interoperative bleeding, abdominal bleeding) [Time frame: from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]
  • Number of hospital free days [Time frame: from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]
  • Number of Ventilator free days [Time frame: from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]
  • Number of ICU free days [Time frame: from the time of hospital admission to the time of hospital discharge or 30 days (whichever occurs first)]
  • Level of Anti-FXa [Time frame: from the time of hospital admission up to hospital day 7]
  • Antithrombin (AT) activity level [Time frame: from the time of hospital admission up to hospital day 7]
  • Change in level of the endothelial marker syndecan-1 as assessed by a blood test [Time frame: time of hospital admission, day1, day2, day 3, day 4, day 5, day6, day 7]
  • Change in level of the endothelial marker thrombomodulin as assessed by a blood test [Time frame: From the time of hospital admission to day 7]
  • Change in level of Inflammatory marker Tumor necrosis factor alpha (TNFα) as assessed by a blood test [Time frame: From time of hospital admission to day 7]
