Brief Summary

The mismatch between organ supply and demand results in the deaths of thousands of Americans each year. Our research group aims to solve this unmitigated health care crisis by translating advances in xenotransplantation to humans and expanding organ supply in a sustainable fashion using genetically modified pigs as a source of organs. We propose here a phase I clinical trial of porcine kidney xenotransplantation into 20 people with end-stage kidney disease. Source donor animals are pigs with 10 gene edits (10-GE) which attenuate immunologic harm to the kidney xenograft. 10-GE pigs are housed in a designated pathogen-free facility within 30 minutes of the transplantation center. Xenotransplantation procedures follow conventional practices currently employed in allotransplantation and comply with multiple regulatory standards to ensure ethical treatment of research subjects and source animals. Recruitment and xenotransplantation will occur over 5 years with study follow-up extending 1 year after xenotransplantation. Primary outcome variables surround patient safety, such as patient survival and the rate of zoonotic disease transmission. Secondary outcome variables include commonly used metrics of graft survival and function.

  • Development of anti-human leukocyte antigen (HLA) antibody/alloantibody sensitization after transplant with a porcine kidney

    It is currently unknown whether porcine kidney xenografts will ever function sufficiently to become a destination therapy for patients with ESKD. However, if porcine kidney xenografts have modest longevity, there may be benefit to temporary rescue from dialysis. Porcine kidney xenografts may then act as a bridge to human allotransplantation. Thus, there is the need to determine whether porcine kidney xenografts provoke the development of anti-HLA antibody and sensitize recipients against human allografts. Such sensitization may prevent xenograft recipients from ever receiving a human allotransplant, and the frequency of this event must be determined in order to counsel patients effectively about the risks of participating in additional trials of xenotransplantation.

Study Arms (1)

Porcine Kidney (UKidney) transplant

EXPERIMENTAL

In this phase I single arm study patients with acute renal failure will be transplanted with a porcine xenograft versus a human allograft-after transplantation the best practice standard of care will be followed for monitoring and immunosuppression with the exception of additional monitoring for potential porcine transmitted infections

Device: UKidney

Interventions

UKidneyDEVICE

The intended clinical product is a kidney derived from a domestic pig that contains an intentional genomic alteration (IGA) to protect it after transplantation from the human immune response via inactivation of endogenous porcine genes responsible for expression of pig epitopes and inclusion of human transgenes to inhibit host immunogenic response.

Also known as: Porcine Kidney, Xenotransplant
