Using warm perfusion to improve kidney transplantation outcomes

Multicenter, Prospective and Open-label Clinical Trial to Evaluate the Viability, Performance and Safety of ex Vivo Normothermic Perfusion in Kidney Transplantation From DCD and DBD Donors.

Not applicable Interventional Ebers Medical Technology, S.L. · NCT05175885

This study is testing a new device that keeps kidneys warm and healthy before transplanting them to see if it helps improve the success of kidney transplants from deceased donors.

What this trial studies

This clinical investigation evaluates the viability, performance, and safety of a device called Ark Kidney, which utilizes ex vivo normothermic perfusion to preserve kidneys from deceased donors before transplantation. The device continuously circulates a warm, oxygenated perfusate through the kidney, allowing for better organ resuscitation and monitoring during the perfusion process. The study focuses on kidneys from both controlled donation after circulatory death (DCD) and donation after brain death (DBD) donors, aiming to enhance transplant success rates.

Who should consider this trial

Good fit: Ideal candidates include patients aged 18 and older on dialysis awaiting their first or second kidney transplant from specific donor types.

Not a fit: Patients with two or more previous kidney transplantations or those receiving dual kidney transplants may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve kidney transplant outcomes and increase the availability of viable organs.

How similar studies have performed: While the concept of ex vivo normothermic perfusion is gaining interest, this specific application in kidney transplantation is relatively novel and has not been extensively tested in prior studies.

Eligibility criteria

Inclusion Criteria:

1. Patients aged 18 years and older
2. Patients undergoing renal replacement therapy by means of dialysis and included in the waiting list for renal transplantation in their respective site.
3. Candidates to receive a first or second renal transplant from (i) a Maastricht type III (Maastricht classification) controlled DCD donor or (ii) a DBD donor aged 70 years or older.
4. Patients that have given informed consent in written form before their inclusion in the study. In case of compromised mental capacity, the approval and signature of a legal guardian will be required.
5. Patients compliant with the requirements of the study and without impediments to follow the instructions throughout the 1-year duration of the study.
6. Patients that meet the acceptance criteria for kidney transplant recipients established in the clinical site in agreement with usual clinical practice.

Exclusion Criteria:

1. Two or more previous kidney transplantations
2. Dual kidney transplantation or multivisceral transplantation (e.g. a pancreas-kidney transplantation)
3. Recipients of an organ with any of the following characteristics:

   1. Expected cold ischemia time before EVNP \> 20 hours
   2. Organ from hepatitis B surface antigen-positive or hepatitis C viremic donor

7. Diagnosis of antiphospholipid syndrome at the moment of inclusion
8. Panel-reactive antibodies (PRA) score \> 50%
9. Known allergies to any of the components of the perfusate
10. Preexisting vascular disease that represents an extraordinary technical difficulty for the transplantation in the opinion of the investigator
11. Presence of clinically relevant donor-specific anti-HLA antibodies
12. ABO incompatibility
13. History of alcohol or drug abuse in the last two years
14. Use of normothermic regional perfusion during the organ harvesting process
15. Participation of the patient in another study or clinical trial.
