New Record Set with Nine Months Dialysis Independence. Mr. Tim Andrews · 271 days with transplant

On January 25, 2025, Tim Andrews, 66, became the second patient to receive an EGEN-2784 genetically edited porcine kidney under the FDA-authorized Multi-Patient Expanded Access Study at Massachusetts General Hospital. 

Before his transplant, Tim had spent more than two years on dialysis, grappling with severe fatigue, declining health, and a heart attack in 2023. His O‑group blood type meant he faced a 5 – 10 year wait for a human kidney. Statistically, he had only a 9% chance of receiving a donor kidney within five years and a 49% likelihood of removal from the waitlist due to illness or death. 

Tim’s transplant transformed his daily life. He was discharged on February 1 and described waking after surgery as ​“a miracle,” saying that ​“the cloud of dialysis lifted the moment I opened my eyes.” For the first time in more than two years, he was living dialysis-free.

In October 2025, the porcine kidney was removed after functioning for nearly nine months, setting a new world record. During his recovery, Tim even threw the first pitch at a Boston Red Sox game, a symbolic moment of strength and celebration.

Tim’s experience provides pivotal validation of the EGEN-2784 program.

“This isn’t about me,” Tim said. ​“It’s about giving hope to the 500,000 people on dialysis. That’s why I did this.”
