Second chance: repeat islet transplants tested for type 1 diabetes

NCT ID NCT07666789

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at whether a second islet transplant can safely improve blood sugar control in adults with type 1 diabetes whose first transplant stopped working. Researchers will follow 20 patients for up to 5 years, checking graft function, insulin use, and severe low blood sugar events. The goal is to understand if re-transplantation is worth the risks, including possible immune reactions.

What this could mean

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

Active substance

islet cells (from donor pancreas)

What this could lead to

If successful, this could show that a second islet transplant helps people with type 1 diabetes regain blood sugar control after the first transplant stops working.

What could go wrong

This is a small, retrospective study (20 people) that looks back at past data, not a controlled trial. Repeated transplants may increase immune reactions that could harm the new graft.
