Can we predict who can safely lower Anti-Rejection drugs after hand or face transplants?
NCT ID NCT02055521
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looked for immune tolerance markers in 18 hand and face transplant recipients (transplanted at least one year prior). Researchers analyzed blood and skin biopsies to find a 'tolerance signature' that might identify patients who could safely reduce their lifelong anti-rejection medication. The goal is to minimize drug side effects while preventing graft rejection.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors identify which transplant recipients can safely lower their anti-rejection drugs, reducing side effects.
- What could go wrong
- This is a small, observational study (18 people) looking for biological markers, not testing a new treatment. The markers may not reliably predict tolerance in hand or face transplants.
