Renal Ex Vivo Warm Advanced Resuscitation Through Machine Perfusion (REWARM)
March 22, 2023 updated by: University Medical Center Groningen
Renal Ex Vivo Warm Advanced Resuscitation Through Machine Perfusion - The REWARM Study
The REWARM study is an open label, randomized controlled clinical efficacy study, with primary outcome renal function 6 months after transplantation of kidneys recovered from deceased donors aged 50 years or older.
Prior to transplantation, kidney grafts in the intervention group will receive 4-6 hours of NMP, following standard HMP and kidneys in the control group will only receive standard treatment, being HMP.
It is a multi-center trial.
Given the total annual 50+ deceased donor kidney transplantation volume of the three participating transplant centers combined, inclusions in the study are expected to last 2.5-3 years, aiming for a total of 140 patients in each of the two arms (280 patients total).

Design Details
- Primary Purpose: Treatment
- Allocation: Randomized
- Interventional Model: Parallel Assignment
- Masking: None (Open Label)
Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Hypothermic machine perfusion
|
|
Active Comparator: Normothermic machine perfusion
|
To determine whether a 4-6 hour period of normothermic machine perfusion, following standard hypothermic machine perfusion, results in better graft function after transplantation, compared to hypothermic machine perfusion preservation alone of kidneys recovered from deceased donors aged 50 years or older
