NCT ID NCT07599293
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study uses healthcare claims data from nearly 40,000 people to see if the results of a major clinical trial (EMPEROR-Preserved) can be reproduced in a real-world setting. Researchers are comparing two diabetes drugs, empagliflozin and sitagliptin, in patients with heart failure with preserved ejection fraction and type 2 diabetes. The goal is to learn when real-world data can be trusted to answer clinical questions.
