Summary

This early-phase trial tests whether a genetically modified pig kidney combined with thymus tissue can work as a transplant in 4 adults with end-stage kidney disease. The goal is to see if the organ can keep them off dialysis safely for at least 6 months. Participants must be on dialysis, eligible for a human kidney transplant, and have a low chance of getting one within a year.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
genetically modified pig kidney-thymus transplant
What this could lead to
If successful, this could provide a new source of transplantable organs for people with kidney failure, reducing the need for dialysis and human donor kidneys.
What could go wrong
This is a very early, small trial (4 people). The pig organ may be rejected, cause serious infections, or fail to work long-term. Lifelong immune-suppressing drugs are needed.
