We are doing this study to learn more about how effective, safe and tolerable an experimental drug called balcinrenone is when used in combination with dapagliflozin for treating patients with heart failure and impaired kidney function and also to better understand the studied disease and associated health problems. Combining balcinrenone with Dapagliflozin is experimental, which means it is not approved by any health authority such as the United States Food and Drug Administration (FDA). Dapagliflozin is an approved drug to treat patients with heart failure, chronic kidney disease and type 2 diabetes mellitus.
