It鈥檚 the latest step in the quest for . A second U.S. company, eGenesis, is preparing to begin its own pig kidney clinical trial in the coming months. These are the first known clinical trials of what is called xenotransplantation in the world.

To protect the study participant鈥檚 identity, researchers aren鈥檛 releasing information about when the NYU surgery was performed or further patient information.

NYU's Dr. Robert Montgomery, who led the transplant team, told The Associated Press his hospital has a list of other patients interested in joining the small trial, which will initially include six people. If all goes well, it could be expanded to up to 50 as additional transplant centers join.

The Food and Drug Administration is allowing the rigorous studies after , with mixed results. The first two gene-edited pig kidney transplants were short-lived.

Then doctors began working with patients who badly needed a kidney but weren't as sick as prior recipients. At NYU, an Alabama woman鈥檚 before she had to return to dialysis. The , was set by a New Hampshire man transplanted at Massachusetts General Hospital; he also is back on dialysis after the pig organ began declining and was removed last month. Others known to be living with a pig kidney are another Mass General patient and a woman in China.

鈥淭his thing is moving in the right direction" as doctors learn from each patient's experience, NYU's Montgomery said. He noted the ability to resume dialysis also gives a safety net.

More than 100,000 people, most needing kidneys, are on the U.S. transplant list, and thousands die waiting. As a potential alternative, scientists are , less likely to be immediately attacked and destroyed by people鈥檚 immune system.

United Therapeutics' trial is testing pig kidneys with 10 gene edits, 鈥渒nocking out鈥� pig genes that trigger early rejection and excessive organ grown and adding some human genes to improve compatibility.
