New study tracks how common heart drug affects kidneys in transplant candidates
NCT ID NCT06868797
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study follows 103 advanced heart failure patients on a transplant waiting list to see how dapagliflozin affects the link between heart and kidney health. Researchers will measure a protein called suPAR in the blood over 6 months to track kidney damage. The goal is to better understand how heart failure and kidney function interact in these patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dapagliflozin
- What this could lead to
- If successful, this could help doctors better understand and manage heart-kidney interactions in advanced heart failure patients.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't prove dapagliflozin's effectiveness. Results may not apply to all heart failure patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age ≥ 18 years and ≤ 85 years 2. NYHA class ≥3 3. LVEF ≤ 35% 4. On GDMT (including dapagliflozin) based on current heart failure practice guidelines at maximal tolerated dose 5. On waiting list (or on the registration pathway) for heart transplantation after multidisciplinary Heart Team decision, with anticipated access to heart transplant ≥ 6 months or in a pre-transplant pathway. 6. Person affiliated to a social security scheme or beneficiary of such a scheme. 7. A person who has received full information about the organization of the clinical research and has signed an informed consent form. Exclusion Criteria: 1. Priority patient on waiting list for heart transplantation. 2. Etiology of heart failure due to or associated with uncorrected thyroid disease, obstructive cardiomyopathy, pericardial disease, amyloidosis or restrictive cardiomyopathy. 3. Inotrope dependent, existence of ongoing mechanical circulatory support 4. Current acute decompensated HF or hospitalization due to decompensated HF \<30 days prior to the enrolment. 5. History of any organ transplant or prior implantation of a ventricular assistance device (VAD) or similar device, or implantation expected after inclusion. 6. Any recent interventional procedure likely to improve symptoms and heart failure status (coronary revascularization, percutaneous mitral valve intervention, cardiac resynchronization therapy) \< 60 days. 7. Glomerular filtration rate \<25 ml/min/1.73 m2, according to CKD-EPI formula 8. Unstable or rapidly progressing renal disease (autosomal dominant or autosomal recessive polycystic kidney disease, lupus nephritis or ANCA-associated vasculitis). 9. Type 1 diabetes mellitus. 10. Participation in another clinical interventional trial. 11. Any condition other than heart failure that could limit survival to less than 12 months. 12. Pregnant women or breastfeeding mothers 13. vulnerable persons (guardianship, curatorship, safeguard of justice)
