A 66-year-old patient, Tim Andrews, survived for 271 days after receiving a genetically modified pig kidney transplant in January 2025.
The transplant allowed the patient to forgo dialysis until October 23, 2025, when the organ was removed due to declining function.
Researchers published the case study in The Lancet on September 3, 2026, highlighting the potential of xenotransplantation to bridge the organ shortage gap.
