Pioneer of pig kidneys talks about their first clinical trial at Orlando conference, next steps

Biotechnology Companies Egenesis and United Therapeutics Corporation report that the FDA introduced a green clinical trial of genetically modified PIG kidney transplant last month.

It's an effort to deal with sad reality. Approximately 90,000 people await kidneys in the United States, 11 on the list die every day, and the United Network for organ sharing estimates have died.

There are many potential solutions, but Robert Montgomery, who led the Nyu Langone Transplant Institute and saved his life with a heart transplant, claimed that the current organ donation system is a “broken paradigm.” If these tests lead to widely available pig organs, that would be the answer, he said on Feb. 27 at the Lake Non-Impact Forum in Orlando, Florida.

“I really focused on trying to improve my career progressively. [organ transplant] The system, but the system cannot provide sufficient organs. And this is the future. This is my hope,” Montgomery said.

Science

Egenesis designed donor pigs with 69 genetic edits, including 59 fine tunings to remove viruses. The New York Times reported February 3rd.

According to a press release on February 7, the company is currently conducting trials of three participants that took place through the FDA's extended access route. Compassionate routes of useHow to Test Hale Mary for People with Severe Illness.

Egenesis announced in this release the success of kidney transplants for the first trial patient. This is the sixth patient who undergoes genetically modified pig organ transplantation.

“This procedure is more than a scientific milestone and represents a new frontier in medicine,” said Michael Curtis, CEO of Egenesis, in a release. “We stand at the beginning of a future in which organ shortages no longer direct patient outcomes.”

There is a lot of excitement about Egenesis' brave gambit. The company raised $191 million Series D finance last September for the exam, led by Lux Capital.

If the biotechnology company's name sounds familiar, it could also be because Azecesis made its first successful kidney xenograft, an animal-to-human transplant that passed away in 2024.

United Therapeutics takes a slightly different approach in the source pig kidneys of 10 gene editing sources. According to a press release on February 3, the trial, scheduled to kick off in mid-2025, will start with six people and expand to up to 50 if things go well.

The trial is open to people aged 55-70 who have been diagnosed with renal failure and have been dialyzed for at least six months and are not eligible for a traditional transplant or on the waitlist for medical reasons, but are not expected to have been transplanted within five years per release.

“Our clearance [Investigational New Drug application] This first clinical trial of Xenokidney represents an important step in its relentless mission to expand the availability of transplantable organs,” said Leigh Peterson, product development and xenograft EVP at United Therapeutics.

Skeptic's cry

However, there are critics of this procedure.

According to The New York Times, there are some concerns about the low risk that the procedure can “spill” pig pathogens into the population. And medical ethicists say that there are so many unknown risks that patients may not fully agree.

Andy Howard, co-chair of the nonprofit advocacy group The Kidney Transplant Collaborative, told Healthcare Brew that the exam is a “exciting progress,” but other routes (such as donating live kidneys) are more realistic ways to solve this problem.

“While this innovation has promise, clinical use is likely at least 10 years away, and waitlist patients don't have that time,” he said.

Towana Rooney, the recipient of the longest living life of genetically designed pig kidneys, is proud of her decision, she said at the Nona Impact Forum.

My 53-year-old grandmother became the fifth person to receive a pig heart or kidney transplant on November 25th. The first four patients He died within months of the transplant, and her family feared that she could meet the same fate.

However, she had no other options. She had been on dialysis for almost nine years, so it was unlikely that she would qualify for a traditional kidney transplant due to air-high levels of antibodies that could reject most donor kidneys in Montgomery, who led the Rooney transplant at NYU Langone Health, was NYU Langone's Health, which led the Rooney Transplant, which was unlikely to qualify for a traditional kidney transplant.

“If you have a family member who is on dialysis or has kidney disease, tell them to go out to faith… don't be afraid,” Rooney said.
