Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Surgery - Kidney transplant biopsy

Experimental: Intervention - Participants with high urine CXCL10 randomized to the Intervention Arm will undergo a kidney transplant biopsy to check for rejection. Biopsy-proven subclinical rejection will be treated per study protocol.

No intervention: Control - Participants with high urine CXCL10 randomized to the Control Arm will continue routine post-transplant surveillance with serum creatinine and proteinuria; serial urine samples will continue to be collected and analyzed (blinded), but not used to direct care.


Treatment: Surgery: Kidney transplant biopsy
Elevated urine CXCL10 will trigger a study biopsy in patients randomized to the intervention arm. Subclinical rejection will be treated per protocol.
