The purpose of this study is to assess the feasibility and safety of mild-to-moderate hypothermia as an in-vivo organ preservation strategy compared to normothermia in 60 brain-dead organ donors.

Condition Intervention Phase
Organ Transplantation From Brain-dead Donors Other: Cold isotonic fluid and central venous hypothermia catheter Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Feasibility of Mild-to-moderate Therapeutic Hypothermia as an In-vivo Organ Preservation Strategy in Brain-dead Donors

Further study details as provided by University of Pittsburgh:

Primary Outcome Measures:
  • Feasibility and safety [ Time Frame: From enrollment to organ procurement (average of 24 hours) ]
    Brain-dead organ donors will be followed from study enrollment up to organ procurement for an average of 24 hours

Secondary Outcome Measures:
  • Six-month hospital free survival in recipients [ Time Frame: 6 months ]
    Data on recipient survival and allograft function will be collected up to 6 months following transplantation

  • Interleukin-6 [ Time Frame: Baseline, 6 hours, and at organ procurement (15-24 hrs) ]
  • Actual no. of organs transplanted [ Time Frame: At the time of organ procurement ]
  • Malondialdehyde [ Time Frame: Baseline, 6 hours, and at organ procurement (15-24 hrs) ]
  • Death receptor-5 [ Time Frame: Baseline, 6 hours, and at organ procurement (15-24 hrs) ]
  • lactate [ Time Frame: Baseline, 6 hours, and at organ procurement (15-24 hrs) ]
  • Urinary isoprostanes [ Time Frame: Baseline, 6 hours, and at organ procurement (15-24 hrs) ]

Enrollment: 4
Study Start Date: March 2012
Study Completion Date: March 2014
Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Hypothermia (32-33 degree C)
Following randomization, hypothermia will be induced by a combination of cold isotonic fluid and sustained until organ procurement by a central venous catheter
Other: Cold isotonic fluid and central venous hypothermia catheter
20-30ml/kg of isotonic crystalloid resuscitation fluid will be used for induction. Hypothermia (32-33 degrees C) will be sustained until organ procurement using an FDA approved central venous catheter connected to an external temperature regulating system
No Intervention: Normothermia (36.5 - 37.5 degree C)
Normothermia will be maintained until organ procurement as per current standard of care
