Genetically modified pig kidney keeps man alive for record nine months
Source: Guardian Health ↗
A genetically modified kidney from a Yucatan miniature pig named Wilma sustained 66‑year‑old Tim Andrews of New Hampshire for a record nine months, serving as a temporary “bridge” until he could receive a human donor organ. Andrews, who suffered end‑stage kidney disease due to type‑2 diabetes and faced a mere 9 % chance of obtaining a human kidney within five years, underwent the xenotransplant in January 2025 at Mass General Brigham in Massachusetts. The pig kidney, edited with 69 genomic modifications to evade viral threats and reduce immune rejection, kept him off dialysis for 271 days before it began to fail, after which a deceased‑donor human kidney was transplanted successfully.
The breakthrough, detailed in a Lancet publication, highlights the acute shortage of human kidneys and positions xenotransplantation as a potential stop‑gap solution. Dr Leonardo Riella of the Center for Transplantation Sciences emphasized that while transplantation remains the optimal therapy for renal failure, the supply‑demand gap forces many patients onto dialysis with high mortality risk. By using a pig kidney as a bridge, patients like Andrews can avoid the debilitating effects of long‑term dialysis, improve quality of life, and await a human organ without the immediate threat of death. The procedure also demonstrated safety: no new antibodies against human tissue were detected, and extensive testing found no pig‑derived viruses or pathogens throughout the transplant course.
Although Andrews’ case represents a single, carefully selected patient under intensive specialist care, the outcome opens the door for broader clinical trials aimed at validating pig kidneys as a bridge therapy. Follow‑up after the human transplant showed stable function for six months, suggesting the xenograft did not sensitize the recipient to future human organs. The research team cautioned that results may not be replicable in all settings and that further studies are required to assess long‑term durability and broader applicability. Nonetheless, the success underscores the willingness of patients to pioneer early‑stage studies and signals a possible shift in addressing the global organ shortage, with xenotransplantation moving from experimental concept toward a viable clinical option.
