Clinical Trial Summary

The aim of the study is to evaluate the feasibility of this bubble and surface oxygenation and to determine the optimal timing of surface oxygenation (continuous versus intermittent) as alternative for membrane-oxygenated kidneys, originating from DCD donors, during HMP on early graft function in clinical practice.


Description:

Kidneys originating from deceased donors after circulatory death (DCD), category 3 and 5 (controlled) will be preserved from procurement until transplantation on hypothermic machine perfusion conditions and prospectively randomized into 2 study groups: 1) intermittent surface oxygenation during HMP (surface oxygenation interrupted during organ transport (2-4h)(I-HMPO2 group), and 2) continuous surface oxygenation during HMP (surface oxygenation during the whole machine preservation period included organ transport)(C-HMPO2 group).

Outcome

Type Measure Description Time frame Safety issue
Primary Functional delayed graft function defined as the absence of a decrease in the serum creatinine level of at least 10% per day for at least 3 consecutive days in the first 7 days after transplantation (not including patients in whom acute rejection of calcineurin inhibitor toxicity is proven on biopsy) first 7 days after transplantation
Secondary Need for dialysis after transplantation Number of dialysis sessions after transplantation 0-30 days after transplantation
Secondary Delayed graft function defined as the need for dialysis in the first 7 days after transplantation and preceding the return of kidney function first 7 days after transplantation
Secondary Serum creatinine reduction ratio alternative definition of DGF= CRR2 < or = 30% Day 1-2 after transplantation
Secondary Graft survival Functional kidney graft at 7 days, 3, 6, and 12 months From 1-365 days after transplantation
Secondary Patient survival (censored and uncensored for death) Patient survival at 7 days, 3, 6, and 12 months From 1-365 days after transplantation
Secondary Glomerular filtration rate at 1 year after transplantation 24-hour creatinine clearance At 1 year after transplantation (window 30 days)
Secondary Estimated glomerular filtration rate eGFR defined by the CKD-EPI equation (Chronic Kidney Disease Epidemiology Collaboration) at 3, 6 and 12 months after transplantation At 3, 6, and 12 months after transplantation with window of 10 days
Secondary Primary non-function defined as the continued need for dialysis at 3 months after transplantation Until 3 months after transplantation
Secondary Biopsy-proven acute rejection Biopsy-proven acute rejection during the 1 year after transplantation Until 1 year after transplantation with window of 10 days
Secondary Metabolic analysis on kidney preservation tissue Metabolic analysis by 1D proton NMR (e.g., succinate, lactate, acetate, formate, hypoxanthine) on a tissue sample taken before (= baseline) and at the end of the preservation period before transplantation of the kidney Baseline and pre-surgery
Secondary Metabolic analysis on kidney preservation tissue Metabolic analysis by liquid chromatography coupled to electrospray ionization mass spectrometry (LC-ESI-MS) (succinate, glutamate, lactate, ATP, ADP, AMP, NADH, NAD+) on a tissue sample taken before (= baseline) and at the end of the preservation period before transplantation of the kidney Baseline and pre-surgery
Secondary Metabolic analysis on preservation fluid Metabolic analysis by 1D proton NMR and fluorescence on a perfusion fluid sample taken before (= baseline) and at the end of the preservation period before transplantation of the kidney Baseline and pre-surgery
