The purpose of this clinical research trial is to look at the effectiveness, safety, and tolerance of combining the investigational trial drug called BI 690517 with empagliflozin (empa) in participants diagnosed with heart failure (HF). Empagliflozin is approved by the FDA for the treatment of heart failure.
In this trial, the investigational new treatment option BI 690517 is compared with a treatment with empa and placebo. You have a 50% chance (much like flipping a coin) of getting BI 690517 with empa, or empa and placebo. Please be aware that you may receive placebo that looks like the trial drug (BI 690517) but does not contain any medicine.
