New drug could help 'Incompatible' kidney transplants succeed
NCT ID NCT07379957
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests imlifidase, a drug that temporarily disables the immune system's antibodies, allowing highly sensitized patients to receive a kidney from a deceased donor they would otherwise reject. The trial will follow 450 patients in France to see how many get transplanted and how well the kidneys survive long-term. Early results suggest it can convert a positive crossmatch to negative in most patients, but antibody rejection and graft loss are still concerns.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Imlifidase (a drug that temporarily disables antibodies)
- What this could lead to
- If successful, this could help more highly sensitized patients get a kidney transplant and improve long-term graft survival.
- What could go wrong
- This is based on two small studies; antibody rejection and graft loss remain possible. Long-term data are still being collected.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
When a kidney transplant candidate eligible to imlifidase is identified in a transplant center in France, HLA antibodies are delisted by the HLA laboratory, according to the French guidelines. Following this delisting, the patients can be transplanted with or without imlifidase or stay on dialysis. Bordeaux University Hospital will establish agreements with the 20 other university hospitals who have patients eligible to imlifidase. An implementation visit will be carried out at each CHU to: 1. identify patients already eligible for imlifidase, 2. set up a system to inform the Bordeaux CHU, as the coordinating center, when new incident patients eligible for imlifidase are identified, 3. offer all identified patients' inclusion in the ISKIA study
