Could this Stem-Cell infusion end insulin shots for diabetics with kidney transplants?
NCT ID NCT06832410
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 3 study tests VX-880, a stem-cell therapy infused into the liver, in 10 people with type 1 diabetes who have already received a kidney transplant. The main goal is to see if participants can stop using insulin entirely. The therapy is given alongside standard transplant drugs to prevent rejection.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- VX-880 (Zimislecel), a stem-cell derived therapy infused into the liver's portal vein
- What this could lead to
- If successful, this could allow people with type 1 diabetes and a kidney transplant to stop taking insulin, while continuing their transplant-related immunosuppression.
- What could go wrong
- This is a very small early-phase 3 trial (only 10 participants). The therapy requires lifelong immunosuppression for the kidney transplant, and it may not achieve lasting insulin independence or could cause side effects.
