ClinConnect Summary

This clinical trial is studying a new way to diagnose a condition called antibody-mediated rejection (AMR) in people who have received a lung transplant. AMR can be hard to identify and often goes undetected until it is too late. Researchers believe that checking for specific antibodies in the lung tissue (called intragraft donor specific antibodies or gDSAs) could help diagnose AMR earlier and improve patient outcomes. The goal is to see if finding these antibodies can help doctors understand how well the lung transplant is working and guide better treatment options.

To participate in this study, you must be at least 18 years old and have received a lung transplant. You also need to have developed certain antibodies against the transplant within the last month. If you join the study, you will undergo tests to check for these antibodies and possibly have a procedure to take a small sample of lung tissue. This research could help improve care for future lung transplant patients, so your involvement may contribute to important advancements in this area.
