NCT ID NCT06642272
First seen Sep 18, 2026 · Last updated Sep 18, 2026
Summary
Researchers compare empagliflozin and dapagliflozin, two similar diabetes drugs, to see which works better at preventing death, heart problems, and kidney damage in adults with type 2 diabetes, heart failure, or chronic kidney disease. The trial uses electronic health records to randomly assign patients to one drug or the other based on the time of day they receive care. About 17,200 patients will take part. The goal is to learn which drug offers better protection for the heart and kidneys.
