C1 esterase inhibitor injected into deceased-donor kidneys before transplant

Intra-graft C1 esterase inhibitor therapy for deceased kidney transplantation

NIH-funded research Cedars-Sinai Medical Center · NIH-11180440

This trial tests whether injecting a medicine called C1 esterase inhibitor into donated deceased kidneys before transplant helps adult recipients recover better and have stronger kidney function.

What this research studies

If I were getting a kidney from a deceased donor, this trial would randomly assign the donated organ to receive an injection of C1 esterase inhibitor into the renal artery before it is implanted or to receive standard care. Doctors will then follow my recovery, early injury after reperfusion, and kidney function over time, including one-year outcomes. The approach builds on earlier single-center pilot trials and preclinical work showing that blocking complement activation may limit ischemia-reperfusion injury. The study is conducted at Cedars-Sinai and focuses on adult transplant recipients of deceased-donor kidneys.

Who could benefit from this research

Good fit: Adults (21+) who are receiving a kidney from a deceased donor and are eligible for standard kidney transplantation would be the ideal candidates.

Not a fit: People receiving living-donor kidneys, pediatric patients, or those who are not undergoing kidney transplantation would not be eligible and would not benefit directly from this trial.

Why it matters

Potential benefit: If successful, the treatment could lower early transplant injury and improve one-year graft function, reducing the risk of delayed graft function and graft loss.

How similar studies have performed: Two single-center randomized pilot trials provided supportive signals that pre-implantation C1 esterase inhibitor may improve outcomes, and this larger randomized trial builds on those findings.
