CTOAD (Cardiothoracic Transplant Outcome Assessment Using dd-cfDNA)

Cardiothoracic Transplant Outcome Assessment Using dd-cfDNA

  • Hospital – Speciality: Cardiothoracic Transplant team, Wythenshawe Hospital and Transplantation Laboratory, MRI 
  • Study type: Human Tissue samples
  • Funder: NHS England

Summary

Monitoring the rejection and injury status of the heart is an important part of post-transplant therapy. Heart transplant recipients have 14 endomyocardial biopsies (EMB) in the first 2 years post-transplant. EMB is the gold standard method of monitoring the heart post-transplant, but it is an expensive and invasive procedure that only identifies rejection in 5-20% of tests. There is evidence to show that donor-derived cell-free DNA (dd-cfDNA), a non-invasive test of heart transplant injury, correlates with EMB results.

This is a feasibility study that will assess the clinical utility of using dd-cfDNA as a marker of heart transplant injury. The study will measure the amount of dd-cfDNA in the plasma of heart transplant recipients at this centre. The results will be compared to the results of EMB and donor specific antibody screening to determine if dd-cfDNA is a reliable marker of heart transplant injury. This study aims to prove that dd-cfDNA can identify heart transplant injury so that patients can have a dd-cfDNA test to reduce the number of unnecessary EMB.
