Assessing blood tests for lung transplant rejection
Official title: Trifecta-Lung cfDNA-MMDx Study: Comparing the Dd-cfDNA Test to MMDx Microarray Test and Central HLA Antibody Test
Run by University of Alberta · NCT05837663 · Data updated 2026-11-12
This study is testing if new blood tests can help doctors better detect lung transplant rejection by comparing them to traditional biopsy methods.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adult lung transplant recipients who can provide informed consent.
✕Probably not a fit
Patients who are unable to give informed consent, those with multiple organ transplants, cancer patients, and pregnant women may not benefit from this study.

What this trial studies
This observational study aims to explore the relationship between donor-derived cell-free DNA (dd-cfDNA) levels and HLA antibodies in lung transplant recipients. It seeks to evaluate the effectiveness of the Molecular Microscope® Diagnostic System (MMDx) in analyzing biopsy samples and blood tests to improve the accuracy of rejection assessments. By comparing traditional biopsy methods with new blood tests, the study hopes to enhance patient safety and diagnostic precision in lung transplantation. The research will involve multiple institutions to gather comprehensive data on lung transplant outcomes.
Why it matters
Potential benefit: If successful, this study could lead to more accurate and less invasive methods for monitoring lung transplant rejection.
How similar studies have gone: Previous studies using similar approaches in kidney transplantation have shown promising results, indicating potential for success in lung transplantation as well.
