2017-002971-24 (EudraCT Number)

Details and patient eligibility


The primary aim of the study is to investigate the effect of empagliflozin on kidney disease progression or cardiovascular death versus placebo on top of standard of care in patients with pre-existing chronic kidney disease. After completion of the interventional part of the study (primary study completion) a subset of participants will be followed up in a post-trial observational (non-interventional) manner for cardio-renal outcomes (estimated study completion date).
