For the first time ever, doctors have transplanted a genetically edited pig kidney into a human suffering from advanced kidney failure.

Such pig kidneys, altered to lower the risk of rejection and disease, have been successfully placed into monkeys and brain-dead human donor bodies.

1. Doctors have performed the first transplant of a genetically edited pig kidney into a human being

  • Doctors at Massachusetts General Hospital (MGH) in Boston transplanted a genetically edited pig kidney into a human patient suffering from advanced kidney failure, marking the first time this has been done.

2. The kidney had 69 gene edits to lower the risk of rejection

  • The pig kidney, provided by eGenesis, underwent 69 genetic edits to remove harmful pig genes and add beneficial human genes.

  • Retroviruses in the pig donor were also inactivated to eliminate the risk of infection in humans.

3. The patient is recovering well and will soon be discharged

  • The recipient, Rick Slayman, 62, underwent a four-hour surgery and is recovering well, expected to be discharged soon.

  • Slayman had type 2 diabetes and high blood pressure, receiving a human kidney transplant in 2018 that began failing after five years, leading to dialysis and hospitalizations.

4. Details Of The Transplant and Treatment

  • The transplant was performed under a compassionate use waiver from the FDA, and Slayman received two new immunosuppressant drugs to prevent rejection.

  • Slayman, who is Black, agreed to the transplant as a potential breakthrough for ethnic minority patients facing unequal access to kidney transplants due to organ shortages and systemic barriers.

5. How This Impacts The Organ Shortage

  • The genetically altered pig kidneys offer hope for addressing the organ shortage crisis, with over 100,000 people in the US awaiting organ transplants, primarily kidneys.

  • More than 1,400 patients at MGH alone are on the kidney transplant waiting list, highlighting the urgent need for innovative solutions like xenotransplantation (transplanting organs from other species).
