NCT ID NCT07379957

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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
