Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Kidneys from donation after circulatory death donors (DCD) deemed suitable for clinical transplantation will be considered for this pilot trial. if the adult recipients provide consent, Kidneys will be perfused using a TGA approved "Kidney Assist," normothermic machine perfusion device. A minimum of one hour perfusion time will be employed directly prior to transplantation. 4 hours will be the maximum perfusion time. Blood, heparinised and oxygenated is the perfusate and requires to be removed using standard cold preservation solution, at the end of the perfusion period, prior to implantation. This normothermic machine perfusion intervention will be performed in the operating theatre by the principal investigator and transplant team, all of whom have completed training in the use of the Kidney assist device. In addition the PI has supervised a PhD student who has utilised this technology with discarded human kidneys, prior to this clinical trial.

Treatment: Devices
Comparator / control treatment
Although this is primarily a feasibility study using 10-20 DCD kidneys, graft outcomes will be also be compred to two separate control groups:
(i) The contralateral (2nd) kidney from the same donor, which will not be machine perfused, and
(ii) Historical data sourced from ANZDATA for the preceding 5 years (01/01/2015-31/12/2020).

Outcomes
Primary outcome [1] 322029 0
Feasibility/implementation of normothermic machine perfusion of deceased donor kidneys prior to transplantation within the Australian setting.
Timepoint [1] 322029 0
Up to 6 months post-transplant.
Secondary outcome [1] 377077 0
Delayed graft function defined as the need for dialysis within the first 7 days. This is assessed on clinical and biochemical grounds ie serum potassium, urea and creatinine levels, as well as clinical fluid overload.
Timepoint [1] 377077 0
Need for dialysis within the first 7 post operative days
Secondary outcome [2] 378902 0
eGFR is assessed using CKD-EPI calculation based on gender, age and creatinine. Based on age, sex and serum biochemistry
Timepoint [2] 378902 0
1 month, 6 months and 1 year post transplant
Secondary outcome [3] 378903 0
Graft survival
Timepoint [3] 378903 0
1, 6, and 12 months post-transplant
Secondary outcome [4] 378904 0
Patient survival
Timepoint [4] 378904 0
1, 6, and 12 months post-transplant

Eligibility
Key inclusion criteria
Consenting adult recipients aged over 18 years who have been allocated a DCD kidney for Transplantation at Westmead Hospital NSW.

They must be able to understand the intervention which is being performed on the kidney, prior to it being transplanted into themselves and the potential complications and be able to give consent freely.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
No paediatric recipient will be included in this trial. Patients who have either mental health or communication issues, such that they cannot consent or understand the trial will also be excluded. However both of these are usually a contraindication to transplantation, if they are unable to comply with standard post transplant care. Furthermore, patients undergoing their 3rd or more transplant or multi-organ transplantation will also be excluded.

Other design features
The other kidney from the deceased donor, not perfused acts as the control, with outcome data being available through ANZDATA. Furthermore, historical data obtained from ANZDATA (2015-2020) will also be used as a second control.
Currently DCD kidneys have approximately 50% incidence of DGF within Australia.

Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
This is primarily a feasibility study to ensure safety with this technology, not previously used within Australia. Provided the small series shows no added complications to the recipients, a larger prospective RCT will be required to confirm statistical benefits in terms of incidence of DGF, allograft survival and eGFR at 1 year.
However trial data from this pilot study will be used and outcomes compared with the non perfused kidney from each deceased organ donor. Outcomes that will be compared will include DGF rate, and eGFR, graft, and patient survivals at 1, 6, and 12 months post-transplantation.

Summary
Brief summary
This is a feasibility study of normothermic machine perfusion technology in human DCD kidneys deemed suitable for transplantation. If preliminary results are encouraging a larger prospective RCT will be required to confirm whether this technology improves Kidney transplant outcomes in the clinical setting. Experimental data and early non randomised clinical studies from Europe appear to show a significant benefit, by reducing the need for post transplant dialysis.
