First genetically-modified pig kidney recipient dies nearly 2 months after transplant

The first person to receive a genetically-modified pig kidney transplant died nearly two months after the surgery, according to his family and the hospital that performed the groundbreaking procedure.

Richard "Rick" Slayman received the transplant in late March at Massachusetts General Hospital, and his passing was announced Saturday.

Slayman, who was 62 years old at the time of his groundbreaking procedure, had received a human kidney transplant in 2018. After that kidney began to fail last year, he agreed to undergo a transplant with a pig kidney.

"After his transplant, Rick said that one of the reasons he underwent this procedure was to provide hope for the thousands of people who need a transplant to survive. Rick accomplished that goal and his hope and optimism will endure forever," Slayman's family said after his passing. "His legacy will be one that inspires patients, researchers, and health care professionals everywhere. Our family asks for respectful privacy as we remember the beautiful soul of our beloved Rick."

The hospital that performed his pig kidney transplant said there is no indication that Slayman's death was the result of his March procedure.

"Mr. Slayman will forever be seen as a beacon of hope to countless transplant patients worldwide and we are deeply grateful for his trust and willingness to advance the field of xenotransplantation," the hospital also said.
