A 66-year-old man, Tim Andrews, survived 271 days with a genetically modified pig kidney at Massachusetts General Hospital before receiving a human donor organ. This case, detailed in The Lancet, demonstrates xenotransplantation as a viable bridge therapy for patients awaiting human kidneys, addressing the critical organ shortage.
A 66-year-old patient at Mass General Brigham survived 271 days on a genetically engineered pig kidney, setting a new record for xenotransplantation. The organ served as a bridge to a human transplant, demonstrating that animal organs can safely sustain patients while they wait for human donors. This success supports the expansion of clinical trials for end-stage kidney disease.
A genetically modified pig kidney kept a 66-year-old man off dialysis for 271 days, marking the longest successful xenotransplant on record. The organ eventually failed, but the patient successfully received a human donor kidney afterward. This case supports the use of animal organs as a 'bridge' to human transplants, with expanded trials planned for 2027.
A 66-year-old man with end-stage kidney disease survived for a record 271 days using a genetically modified pig kidney, successfully bridging the gap to a human donor transplant. Published in The Lancet, the case confirms that xenografts can prevent dialysis-related deterioration without compromising future human organ acceptance. While the pig kidney eventually failed due to vascular damage, the patient received a human kidney in January 2026 with no adverse immune reactions. This milestone supports the expansion of clinical trials, with eGenesis planning to treat 33 patients across the US by 2027.
A 66-year-old US man, Tim Andrews, survived 271 days with a genetically modified pig kidney, setting a new record for xenotransplantation. The organ acted as a bridge, freeing him from dialysis until it failed, after which he received a human donor kidney. This milestone supports the use of pig organs to bridge the gap in the severe US organ shortage.
A 53-year-old brain-dead man received a genetically modified pig liver and two pig kidneys. The organs functioned for about five days; the liver started bile production within 19 hours and kidney function normalized, suggesting feasibility. However, within 36 hours signs of rejection appeared as pig cells were replaced by human cells and inflammatory markers rose, indicating the need for immune-targeted therapies. The pig had six genome edits (three human genes added, three pig genes removed) to reduce rejection, marking a major step toward addressing organ shortages while highlighting ongoing challenges in long-term compatibility.
Tim Andrews, one of the first recipients of a genetically modified pig kidney, has now received a human kidney after the pig organ failed, marking a historic step in xenotransplantation and illustrating its potential to address organ shortages and reduce dialysis. Researchers are refining immunosuppressive regimens and planning additional xenotransplants as trials move forward.
Tim Andrews—one of the first recipients of a genetically modified pig kidney—has now received a human kidney, becoming the first in that small group to cross from animal to human organ. The pig kidney lasted 271 days before rejection, after which he returned to dialysis; days later he underwent a near-perfectly matched human kidney transplant. The case highlights xenotransplantation as a potential bridge to address the organ shortage, with ongoing research to refine immunosuppression and improve graft survival and plans for additional trials.
A leading surgeon, Dr. Robert Montgomery, discusses the potential of pig organ transplants, which have been gene-edited to reduce rejection, as a promising solution to the organ shortage crisis, with initial trials showing positive results and the possibility of future improvements making pig organs potentially superior to human ones.
A 71-year-old man in China received the first successful genetically modified pig liver transplant, marking a significant milestone in xenotransplantation. Although the patient passed away after 171 days due to complications, the procedure demonstrated the potential of animal organs in human medicine, highlighting both progress and ongoing challenges in the field.
Chinese surgeons successfully transplanted a genetically modified pig lung into a brain-dead human, with the lung functioning for nine days without rejection or infection, marking a significant step in xenotransplantation despite ongoing challenges.
Surgeons successfully transplanted a genetically modified pig lung into a brain dead human, functioning for nine days, marking a significant but preliminary step in xenotransplantation to address organ shortages, with ongoing challenges in immune response and long-term viability.
Researchers at Duke and Vanderbilt have developed new, simpler methods to recover hearts from donation after circulatory death (DCD), potentially increasing the number of hearts available for transplant and saving more lives, especially among children and adults in need of urgent transplants.
Researchers at Duke and Vanderbilt are developing new, simpler methods to recover hearts from donation after circulatory death (DCD), potentially increasing the number of hearts available for transplant and saving more lives, especially among children and adults with heart failure.
A 62-year-old man, Richard Slayman, has become the first person to receive a genetically modified pig kidney transplant, marking a significant milestone in xenotransplantation. The successful procedure, conducted at Massachusetts General Hospital, offers hope for addressing the organ shortage crisis. While more research is needed before interspecies organ transplants become widely available, this breakthrough represents a promising solution to the shortage of organs for transplantation.
