Gene-edited pig kidneys enable patients to go months without dialysis before receiving human transplants

Doctors at eGenesis reported that two patients who received genetically engineered pig kidneys were later able to receive human donor kidneys after a period on dialysis. The transition was not seamless; each patient had the xenograft removed and returned to dialysis for several months before a human organ became available.

The ability to spend a substantial time off dialysis demonstrates a milestone for xenograft research, confirming earlier primate studies that suggested the pig kidneys would not provoke problematic antibodies.

The cases mark the first successful handoff from a pig kidney to a human kidney in clinical settings, highlighting progress in interspecies transplant technology.

eGenesis is among a small group of biotech firms pursuing xenografts, and the outcomes may influence future development of pig organ transplants for patients with kidney failure.
