Andrews successfully lived with the genetically edited pig kidney for 271 days without needing dialysis before receiving a human kidney from a donor. [^1]

Tim Andrews, a 66-year-old patient with end-stage kidney disease, received a genetically edited pig kidney in January 2025 and subsequently received a human kidney in January 2026. [^2]

Tim Andrews, a patient at Mass General Brigham hospital in the US, received a kidney transplant from a pig that functioned for 271 days, which the medical team states is the longest duration on record. [^3]

Lead author Leonardo Riella, M.D., Ph.D., of Mass General Brigham stated that xenotransplantation could help address the organ shortage gap by initially serving as a bridge to get patients off dialysis while they wait for a human donor kidney. [^4]

This case represents the longest dialysis-free survival following porcine kidney xenotransplantation in a living human and the first transition to human kidney transplantation. [^5]

In the US, approximately 100,000 people are waiting for a kidney transplant while only 25,000 transplants occur each year. [^6]

The medical team at Mass General Brigham says their work demonstrates that pig organs can serve as a bridge until a human transplant becomes available. [^7]

The patient had required dialysis for two years prior to the intervention due to failed kidneys. [^8]
