The second person ever has received a transplant with a genetically modified pig kidney.

The recipient was Tim Andrews, a 66-year-old New Hampshire resident who had end-stage kidney disease and was on dialysis for more than two years.

The first recipient of a gene-edited pig kidney died from cardiac causes 52 days after xenotransplantation. The world's first recipient of a gene-edited pig kidney died from cardiac causes within 2 months, but there was no evidence of xenograft rejection, a brief report detailed.
