Clinical Trial Summary

End-stage renal disease (ESRD) is a significant clinical problem for which dialysis or transplantation is required. The current need for kidneys for transplantation vastly exceeds the supply available from live donors, necessitating the use of kidneys from deceased donors. However, kidneys from deceased donors are associated with reduced viability, as lack of blood supply upon cardiac death increases tissue damage. In addition, the standard protocol for cold preservation of donor kidneys between procurement and transplantation increases the risk of delayed donor kidney function by 23% for every 6-hours of storage. Moreover, compared to other organs, the kidney is particularly prone to transplantation-induced injury due to its high metabolic activities and oxygen consumption. Hence, any minor disturbances in blood supply can easily lead to kidney injury. Therefore, it is not surprising that deceased donor kidneys have a low tolerance for damage associated with lack of blood supply. The focus of the investigators research has been to pioneer the development and supplementation of existing kidney preservation solutions with novel hydrogen sulfide (H2S) donor molecules to improve kidney viability for clinical transplantation. Specifically, the investigators demonstrated that supplementation of standard kidney preservation solutions with non-clinically viable H2S donor molecules significantly increased donor kidney protection and prolonged transplant recipient survival in murine and porcine models of kidney transplantation. Having shown the same salutary effect using sodium thiosulfate (STS; a clinically viable H2S donor drug) in rat kidney transplantation, the investigators aim to repeat this work using STS in porcine and clinical kidney transplantation. This single-blind study will enroll participants receiving a kidney transplant. Through randomization, half of the participants will receive STS through administration into the pump the kidney is placed on after procurement from the donor and before transplant to the recipient. Participants will be followed for 1-year post transplant where blood and urine will be collected to determine graft function.
