Pig kidneys could offer a solution to the critical organ shortage, with kidney patients expressing eagerness for xenotransplantation clinical trials to commence, according to a new report by the National Kidney Foundation (NKF). The 'Voice of the Patient' report, stemming from an Externally-Led Patient-Focused Drug Development (EL-PFDD) meeting, underscores the urgent need to explore alternative solutions, as an average of 14 Americans die daily while awaiting life-saving organ transplants.
Addressing the Organ Shortage Crisis
Xenotransplantation, which involves using non-human cells, tissues, or organs like those from pigs, holds promise in addressing the severe shortage of transplantable organs. Currently, kidney xenotransplantation remains in its early stages and is approved only under rare, emergent circumstances, with no clinical trials yet permitted by the FDA. Future trials are crucial to evaluate the safety and efficacy of this approach.
"Xenotransplantation represents a transformative opportunity to address the organ shortage crisis, but it must be guided by the lived experiences of the most important stake holders in this process - patients and their care partners," said Dr. Vineeta Kumar, Professor of Medicine at the University of Alabama and EL-PFDD co-chair. "The insights shared by stake holders during this meeting underscore the urgency of advancing research responsibly while ensuring that patient safety, concerns, and hopes remain central to every step of the process."
Patient Perspectives and the Burden of Dialysis
Participants at the EL-PFDD meeting voiced their frustrations with the lengthy wait times for clinical trials and expressed a strong desire for accelerated progress. Many patients described the debilitating effects of dialysis, including exhaustion, isolation, and an inability to lead normal lives, as key motivators for their willingness to participate in trials, despite the associated risks. The report highlights that patients view xenotransplantation as a potential means to bypass the misery of dialysis and the uncertainty of waiting for a transplant.
The 'Voice of the Patient' report captures both the hopes and concerns surrounding this emerging field, with direct quotes and testimonies from patients and care partners affected by kidney disease. For many, dialysis was described as "dehumanizing" and a significant barrier to living a full life. One participant shared how their daughter's life was "tethered to being on a machine every night for 10 hours," illustrating the profound restrictions imposed by dialysis.
Call to Action
Polling data from the meeting underscored the urgency of the situation, with a majority of participants advocating for faster progress in clinical trials. Patients and their families believe that the risks of inaction, including preventable deaths and prolonged suffering, outweigh the uncertainties associated with xenotransplantation. Their collective voice sends a powerful message: advancing clinical trials is not just a scientific imperative but a vital step toward alleviating the immense burden on patients and their families.
"This is a watershed moment for the future of transplantation," said Kevin Longino, CEO of NKF and a transplant recipient. "NKF is committed to ensuring that patient voices shape the development of xenotransplantation to maximize its life-saving potential."
The NKF is urging researchers, regulators, and policymakers to act on these patient insights by prioritizing the development of clinical trial frameworks for kidney xenotransplantation. The 'Voice of the Patient' report will serve as a cornerstone of this advocacy, ensuring that patient perspectives remain central to the process.

Kidney Disease Statistics
In the United States, over 35 million adults are estimated to have chronic kidney disease (CKD), with approximately 90% unaware of their condition. About 1 in 3 adults in the U.S. are at risk for kidney disease, with risk factors including diabetes, high blood pressure, heart disease, obesity, and family history. Certain populations, such as Black or African American, Hispanic or Latino, American Indian or Alaska Native, Asian American, or Native Hawaiian or Other Pacific Islander individuals, face an increased risk of developing the disease.
