Transplanted gene-edited pig kidney functions for record 285 days in patient
A woman has lived without dialysis for over nine months following an experimental xenotransplant.
The short version
- A patient at Massachusetts General Hospital has lived without dialysis for over nine months with a gene-edited pig kidney, reaching 285 days of organ function.[Wired]
- The milestone surpasses the previous xenotransplantation record of 271 days and marks the fifth recipient of an eGenesis pig kidney under the FDA's expanded access pathway.[Wired]
- The FDA has cleared eGenesis to launch a formal clinical trial of up to 33 kidney failure patients beginning in 2027.[Wired]
Key facts
- A patient at Massachusetts General Hospital has lived without dialysis for more than nine months with a gene-edited pig kidney.[Wired]
- The pig kidney functioned for 285 days, breaking the prior record of 271 days set by Tim Andrews.[Wired]
- The patient is the fifth individual to receive a genetically modified pig kidney from eGenesis via the FDA's expanded access pathway.[Wired]
- Previous recipient Tim Andrews' pig kidney eventually failed due to tiny blood clots before he received a human transplant.[Wired]
- The FDA approved eGenesis to conduct a formal trial in up to 33 patients aged 50 to 70 starting in 2027.[Wired]
What remains uncertain
- The long-term durability of the transplanted pig kidney remains unknown, as organ rejection or clotting can occur at any time.[Wired]
