Clinical Trial Summary

To protect kidney function during the transplantation process by inducing mild hypothermia in the deceased organ donor before organs are recovered


Clinical Trial Description

The number of kidneys available for transplantation in the U.S. (~15,000/yr) does not meet demand (~80,000/yr). This discrepancy will likely worsen given the increasing U.S. prevalence of chronic kidney disease and is compounded by sizable organ attrition once organs have entered the donation process (25-30% attrition in Region 5). Furthermore, worsening renal function in donation after neurologic determination of death (DNDD) organ donors (an increasingly important source of allografts) is one of the strongest predictors of delayed graft function (DGF) and slow graft function (SGF) in the recipient. Both DGF and SGF are associated with decreased long-term organ survival and are of major concern to the transplant community.

To alleviate the aforementioned supply-demand imbalance, there are two major unmet needs that must be urgently addressed. First, active medical interventions that are tested prospectively to protect the organ during the donation process hold sizable potential, but remain exceedingly rare. Second, compliance with pre-defined donor management protocols to restore and stabilize deceased organ donor physiologic functions remains low across different donation service areas, despite evidence that these protocols may improve organ yield.

The goal of this proposal, therefore, is to demonstrate that (1) therapeutic hypothermia as an active medical intervention for the DNDD donor and (2) compliance with donor management protocols can substantially improve allograft function and survival.

The investigators will accomplish this goal by extending an existing research infrastructure (HRSA, R380T10586) across several donor service areas. As such, the investigators will bring together a research network and use the power of this network to properly test a simple medical intervention, therapeutic hypothermia for renal protection, in a prospective randomized single blinded trial. Therapeutic hypothermia is an established cytoprotective intervention that has been demonstrated to be highly protective of organs in select critically ill patients. By combining two of the largest donation service areas in the nation (CTDN, Northern California and OneLegacy, Southern California), the investigators will have access to approximately 10% of all organ donors in the nation. This proposal aims to randomize 500 DNDD organ donors, the biggest cohort enrolled in a prospective randomized trial.

The investigators will further leverage this network to track trial specific donor management protocols variables goals and drive tighter compliance with already established donor management protocols across all donor service areas in Region 5. This will allow the investigators to compile a large historical control cohort that will facilitate answering additional research questions with great detail. All organ procurement areas in Region 5 have confirmed their willingness to participate in this effort and contribute relevant organ donor data via a shared web-portal. Through this active participation, a secondary gain will be improved reporting of donor data and compliance with already accepted donor management goals.

Test of feasibility will be improvement in various kidney function metrics that are commonly used to evaluate organ health during the donation process. Ultimately, the investigators believe this multi-pronged approach may lead to 800 to 1000 additional kidneys that are successfully transplanted nationwide each year. ;
