Urine CXCL10 Monitoring for Kidney Transplant Rejection
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new method to detect kidney transplant rejection early by identifying a marker in urine called CXCL10. The goal is to determine if treating this early sign of rejection can improve the long-term health of the transplanted kidney. Participants with a kidney transplant and high CXCL10 levels might undergo a biopsy (a small tissue test) to check for rejection. Those with high urine CXCL10 levels and no urinary tract infection are suitable candidates for this trial. As a Phase 2, Phase 3 trial, the research measures the treatment's effectiveness in an initial, smaller group and represents the final step before FDA approval. Participants have the opportunity to contribute to potentially groundbreaking advancements in kidney transplant care.
Do I need to stop my current medications to join the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, it mentions that participants should intend to use a maintenance immunosuppression regimen with specific drugs, so you may need to adjust your medications accordingly.
What prior data suggests that this protocol is safe for kidney transplant patients?
Research has shown that kidney transplant biopsies, like those used in this trial to check for rejection, are generally safe. A biopsy involves taking a small piece of kidney tissue to look for signs of rejection.
Studies have found that most patients handle these biopsies well. While some risks exist, such as bleeding or infection, serious problems are rare. Doctors use imaging tools, like ultrasound, to guide the needle and reduce risks.
For those considering joining a trial that includes a kidney biopsy, it's important to know that these procedures have been safely used in many other studies and medical settings. Discuss any concerns with a healthcare provider to ensure all necessary information is available.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores using urine CXCL10 levels to potentially identify kidney transplant rejection earlier and more accurately than current methods, like regular blood tests and biopsies. Current options often involve detecting rejection after damage has occurred, but this approach aims to catch signs of trouble earlier, potentially before symptoms appear. By identifying rejection sooner, doctors might be able to intervene more effectively, improving outcomes for transplant patients.
What evidence suggests that this trial's treatments could be effective for kidney transplant rejection?
Research has shown that urinary CXCL10 could be useful for monitoring kidney transplant health. This marker might help detect early problems, such as rejection, when the body attacks the new kidney. In this trial, participants with high urine CXCL10 levels will be randomized into different arms. Those in the Intervention Arm will undergo a kidney transplant biopsy to check for rejection, with biopsy-proven subclinical rejection treated per study protocol. Meanwhile, participants in the Control Arm will continue routine post-transplant surveillance without biopsy intervention. Previous studies have not demonstrated that monitoring CXCL10 alone improves one-year outcomes. However, early detection using this method might still help maintain kidney health over time. The current focus is on whether early detection can lead to better results for kidney transplant patients.678910

Are You a Good Fit for This Trial?
Adults over 18 who've recently had a kidney transplant can join this trial. They must understand the study, agree to follow its rules, and be available for its duration. Participants need an elevated urine CXCL10 level without infection or significant bleeding in their urine. Those with certain immune mismatches, other organ transplants, conditions affecting safe participation or data quality, incompatible blood types, high antibody levels against the donor kidney, or not following standard anti-rejection drugs cannot join.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Post-transplant Surveillance
Routine urine CXCL10 screening from 2 weeks to 9 months post-transplant to monitor for elevated levels indicating risk of rejection
Intervention
Participants with high urine CXCL10 undergo randomization; intervention arm receives kidney biopsy and treatment for subclinical rejection, control arm continues routine surveillance
Follow-up
Participants are monitored for safety and effectiveness after treatment, including assessment of long-term outcomes
What Are the Treatments Tested in This Trial?
Interventions
- Kidney transplant biopsy
Trial Overview
The trial is testing if treating kidney transplant rejection early based on urinary CXCL10 levels improves long-term outcomes of the new kidney. It's a controlled study where some patients will receive treatment based on these biomarker levels while others may follow standard care protocols.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Active Control
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.
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.
