Brief Summary
This is a study to collect information to assess if transporting hard-to-place (HTP) donor kidneys to a central preservation and assessment facility with dedicated organ assessment capabilities increases allocation success to transplant hospitals.

Study Arms (1)
Hard-to-Place (HTP) Donor Kidneys
The study will be open to all eligible HTP kidneys from male and female donors at all participating Organ Procurement Organization (OPO) study sites. Consent for both organ donation for transplant and medical research will be obtained from the legally authorized party (LAP) by the OPO Coordinator using industry standard consent procedures and documents.
Interventions
Human kidneys from HTP deceased donors will be transported to the Sponsor's central preservation and assessment facility and placed onto a machine perfusion system in a sterile operating room for a brief period of Sub-Normothermic Machine Perfusion (SNMP). Basic parameters including internal renal resistance, oxygen, and electrolyte levels will be recorded using standard point-of-care hospital analyzers. Accepted kidneys will be transported to a participating transplant center using a portable oxygenated LifePort Hypothermic Machine Preservation (HMP) device.
Eligibility Criteria
The study population includes hard-to-place (HTP) deceased donor kidneys retrieved from donation after brain death (DBD) and donation after circulatory death (DCD) donors aged 16- 75.
You may qualify if:
- Be considered HTP, by receiving refusals from every transplant center within the 250 nm allocation radius or similar definition by the local OPO.
- From a Male or female deceased donor, aged 16- 75 years old.
- Kidney initially procured, preserved, and packaged with intent to transplant.
- LAP provides informed consent for organ donation for transplant and research purposes.
- The HTP donor kidney must be allocated to a participating transplant center by a participating OPO, and the transplant center makes the decision to send kidney to Sponsor's central preservation and assessment facility for SNMP assessment and preservation prior to determining suitability for allocation.
You may not qualify if:
- From a Donor with pre-admission diagnosis of end stage renal failure.
- Obvious surgical damage to artery(s), vein(s), or ureter(s) preventing machine perfusion.
- From a donor with confirmed HIV (+), HBVSAg (+) and/or HCV NAT (+) serology results.
- No LAP consent for both transplant and research purposes.
- Cannot arrive to Sponsor's central preservation and assessment facility before reaching 24 hours of cold ischemic time (CIT).

Biospecimen
Sponsor will collect kidney perfusate and urine samples at 90- and 120-minutes during SNMP to store in a -80C specimen freezer for future analysis or quality assurance. Sponsor will collect a 4mm core punch biopsy at the superior pole of the kidney for research use. Research testing of samples may include cytokine, ATP, metabolomics, transcriptomics, proteomics, genomics, dynamic contrast imagery (DCI) and/or hematoxylin and eosin (H\&E) histologic staining. All donor kidneys enrolled in this study will have legally authorized consent for organ donation for transplant and research purposes.

Standard data will be obtained from the Organ Procurement and Transplantation Network (OPTN), which is readily available to the public via request to the Health Resources Service Administration (HRSA), in de-identified form to protect privacy. These standard data include information about the organ donor, preservation procedure, the recipient's kidney transplant, and post-operative follow-up.
